    The invention relates to a thermal management system for a motor vehicle. The invention also relates to a thermal management method implemented by such a thermal management system.
    The thermal comfort in a passenger compartment, such as a passenger compartment, is traditionally obtained by acting on the flow, temperature, humidity and orientation of the air blown into the passenger compartment through different aerators.
    The provision of aerators in vehicles, especially at the front, or near the rear passengers, whether at the side posts between doors, or at the center console or sometimes the flag, and the management of flow and air temperatures are intended both to provide pleasant local conditions for each passenger, but also to control the average temperature of the passenger compartment around 20 ° C generally. Other elements of the passenger compartment, such as windows, the dashboard, the steering wheel or the seats also participate by contact or radiation to the feeling of comfort or thermal discomfort of the driver or a passenger of the vehicle .
    We have seen appearing additional devices to improve and / or customize the thermal comfort by contact, such as heated or refreshing seats, or the heated steering wheel.
    Moreover, in winter and in summer the windows are at a temperature close to the temperature of the outside and their infrared radiation to the passengers contributes significantly to the sensation of comfort or thermal discomfort. Glazing treatment has reduced solar radiation entering the cabin. More recently, the treatment of glazing on the internal face with low emissivity coatings makes it possible to reduce the infrared radiation of the glazings towards the passengers.
    The feeling of thermal comfort in a passenger compartment therefore results from the combination of different heat inputs, especially by convection with air, radiation glazings and internal walls, and contact with the seat.
    In known solutions, airflow and temperature management is the main variable for adjusting thermal comfort.
    The laws of thermal comfort are mainly based on flow and air temperature curves depending on the ambient temperature, to be respected according to a goal of comfort to reach.
    Thus, it is known to use automated control systems for an air conditioning installation, that is to say including including heating, ventilation and / or air conditioning, within a vehicle. Such control systems automatically manage the thermal comfort from at least one selected aerothermal parameter (such as the temperature of the airflow, the flow rate of the airflow and / or the distribution of the air flow towards the passenger compartment through one or more aerators) and external data such as the difference in indoor / outdoor temperature, the solar flux received by the occupant or occupants of the passenger compartment, etc.
    There are known control systems comprising an infrared sensor for measuring the skin temperature of the head of a passenger and which use the temperature detected to adjust / modify the aerothermal parameters in the passenger compartment whose temperature, flow, distribution of 'air.
    In particular, patent FR 2 917 855 discloses a control system provided with at least one sensor including physiological data, such as an infrared sensor capable of measuring a plurality of thermal quantities each related to a body area of a passenger or of the driver of the motor vehicle. The measurements made by this sensor are used within the control system to determine a thermal comfort data of the passenger and this thermal comfort data is used for the adjustment of the air temperature, the air flow and the distribution. air. In particular, it is known from this document to measure the interior temperature of the passenger compartment and the body temperature of the occupant (s) of the vehicle at different levels, in particular on various particular points of the face such as the nose, the cheeks and the forehead, to determine a thermal comfort data of the latter. This thermal comfort data is determined according to a mathematical formula based on the thermal sensation of a representative panel of the population whose body temperature has been measured under different conditions.
    In the previously described solutions, the management of thermal comfort is based on management of the average temperature of the passenger compartment, including the control of one or more instructions on the air in the passenger compartment. A sunshine sensor is also sometimes used to correct the laws of comfort according to the direct solar flux received by the occupants of the vehicle.
    However, the thermal power used to ensure the thermal comfort of the vehicle occupant (s) is often disproportionate to the actual needs. In particular, for an electric vehicle when one wants to heat the cabin for example, energy losses can not be used as is the case for a vehicle with a heat engine, and this leads to additional power consumption.
    The power used is all the more important in transient situations, typically when entering a vehicle in summer or winter, to achieve thermal comfort as quickly as possible and reduce the discomfort of the occupants during these phases. transient conditioning of the passenger compartment.
    In addition, the thermo-physiological needs to compensate for a hot or cold environment in the body of a person are of the order of a few hundred Watts while the powers implemented for the thermal regulation in a passenger compartment are order of a few kilo-Watts. This follows from the fact that the known solutions do not merely satisfy a thermal comfort temperature condition for the occupant or occupants of the vehicle, but establish a temperature of thermal comfort throughout the passenger compartment.
    A global management logic on the air is not enough. In particular, thermal inputs should be managed more locally in order to better adapt to the needs of the occupants of the vehicle.
    Moreover, the vehicles tend to be more and more autonomous which can lead to changing the position of the occupants in the passenger compartment so that the arrangement of aerators for example would no longer be relevant. The thermal comfort management strategy must be redesigned so that it can adapt to the possible changes in position in the passenger compartment. The invention therefore aims to at least partially overcome these disadvantages of the prior art by providing a thermal management system for regulating the thermal state of an occupant, while reducing the thermal power implemented. For this purpose, the present invention proposes a thermal management system for a motor vehicle, said vehicle comprising at least two equipment, said thermal management system comprising: at least one sensor capable of measuring at least one variable that can be used for the determination of at least one thermal comfort datum representative of the thermal state of at least one occupant of said vehicle; a predefined number of actuators respectively configured for adjusting at least one parameter of an associated equipment capable of regulating the thermal state of the occupant, and - an actuator control device capable of: • depending on the measurements of said at least one sensor, determining at least one thermal comfort data, and able to • use said at least one comfort data item to determine if thermal regulation is necessary and for control of the actuators.
    According to the invention, the control device comprises at least one treatment means for depending on said at least one thermal comfort data: identifying at least one first device making it possible to act on a first part of the occupant's body; and a second device making it possible to act on a second part of the body of the occupant, for example different from the first part, and to control at least a first actuator configured for adjusting at least one parameter of the first identified equipment and controlling a second actuator configured to adjust at least one parameter of the second identified equipment to act on said occupant body parts, for example to act differentially on different parts of the body of the occupant. occupant.
    Thus, the invention allows to act differentially on one or more parts of the body, such as the head, neck, shoulders, hands, feet and ankles, arms, legs, torso, back , by local application of heat flows for example of different natures. The thermal management system makes it possible to act on the occupant directly and not only on the environment of the occupant.
    In particular, the invention makes it possible to combine several equipment forming thermal sources to act at different points of the body of the occupant of the vehicle. The term "heat source" means an element or equipment that can deliver hot and / or cold in the form of a heat flow, for example a hot air flow and / or a cold air flow, or a flow by thermal radiation.
    This differentiated action on the body is particularly interesting for applying positive stimuli in transient situations, such as reception phases. In fact, until the body reaches a thermo-neutrality localized thermal stimuli, provide the occupant with a generally positive feeling.
    The combination of thermal sources available in the vehicle on different parts or body areas of the occupant provides individualized comfort at the lowest energy cost. Indeed, by acting closer to the user, it reduces the energy consumption necessary to bring the occupant in a thermal comfort zone compared to the solutions of the prior art which focus solely on the thermal environment of the occupant.
    More particularly, the thermal management system according to the invention is adapted so that the first part of the body of the occupant and the second part of the body of the occupant are different, the thermal management system being able to act differentially on the different parts of the occupant's body.
    According to a preferred embodiment, the thermal management system comprises a means of acquiring at least one temporal information of a usage scenario of said vehicle, said at least one temporal information being usable for the identification of said equipment to control to locally regulate the thermal state of the occupant on different parts of his body.
    "Vehicle Use Scenario" is a scenario that defines how to use the vehicle and the interaction of the occupant (s) with the vehicle. In particular, the use scenario of the vehicle may include a sequencing in the time of the use of the vehicle, for example if the occupant has just entered the vehicle, or if he has been sitting for a long time in the vehicle, or the length of time the vehicle has been driven, and whether the vehicle is in manual or automatic driving mode.
    According to one embodiment, said at least one sensor comprises at least one thermal state sensor capable of measuring at least one thermal value relative to the thermal state of at least one occupant of said vehicle, such as an infrared sensor. In particular, infrared mapping of the face (nose, cheeks, forehead) is a rich and robust data and allows a measure of comfort on thermophysiological quantities directly representative of the feeling of comfort.
    The at least one thermal state sensor may include at least one wavelength sensitive camera located in the mid-infrared spectrum.
    Alternatively or additionally, said at least one thermal state sensor may comprise at least one camera sensitive to wavelengths located in the visible spectrum and / or in the near infrared spectrum.
    According to an exemplary embodiment, said at least one sensor comprises a predetermined number of sensors of the thermal environment in the passenger compartment of said vehicle. The control device is able to use the measurements of the sensors of the thermal environment for the determination of at least one thermal comfort data of the occupant.
    For example, the sensors of the thermal environment in the passenger compartment are able to measure at least one parameter chosen from aerothermal parameters, the temperature of the surface of a device in the vehicle, such as at least one seat or the steering wheel or at least one window, a difference in temperature between the interior and exterior of the passenger compartment, the average interior temperature in the passenger compartment, the solar flux. The sensors of the thermal environment in the passenger compartment can also detect the operation of equipment for regulating the thermal state.
    According to a preferred embodiment, the control device comprises at least one processing means for determining said at least one thermal comfort data of the occupant using an algorithm operating on the basis of a comfort model selected comprising at least one thermo-physiological model based on the thermal sensation of a representative panel of the population whose body temperature has been measured under different conditions.
    In particular, the passenger thermal comfort management system is able to use and combine the measurements relating to the thermal state of the occupant, for example the measurements of the infrared emission of the passengers, combined with the exploitation of the model. chosen thermal comfort, to quantify and predict the feeling of comfort of one or more occupants of the vehicle.
    According to one aspect of the invention, the first and second equipment allow thermal exchanges of different nature, for example by convection, or by radiation, or by conduction. The activation of at least two equipment of the vehicle for heat exchange of different nature - convective, radiative or contact - allows to bring locally heat flows necessary for the implementation of thermal comfort.
    According to an exemplary embodiment, at least one actuator is configured for adjusting at least one aerothermal parameter of an equipment of a heating, ventilation and / or air-conditioning installation of said vehicle, such as the temperature, the flow rate and the temperature. distribution of an air flow to the passenger compartment.
    According to an exemplary embodiment, at least one actuator is configured for adjusting at least one thermal parameter of a device provided in the passenger compartment of said vehicle, such as a window, the steering wheel, a seat, so as to regulate the thermal state of the occupant at a given part of the body.
    This is for example to change the surface temperature of the given equipment.
    According to another aspect of the invention, one of the different parts of the occupant's body is at least one area of the face, the neck, at least one shoulder, the torso, the back, at least one hand, at least one arm , at least one leg, at least one foot and / or ankle.
    According to another aspect of the invention, the thermal management system comprises at least one locating means capable of locating at least part of the occupant's body in space. The locating means is for example able to use the measurements made by said at least one sensor, in particular said at least one thermal state sensor, for locating at least part of the occupant body in space.
    Advantageously, the locating means is able to determine the position of the body of the occupant. One of the advantages of the invention is to be able to adapt to the evolution of automobile uses, in particular the fact that passengers will be able to adopt different positions in the passenger compartment when the vehicle will have an increasingly independent driving. For example, in the case of autonomous driving, occupants may have their heads turned towards each other to discuss.
    According to one embodiment, said at least one sensor is capable of capturing at least one image or sequence of images advantageously infrared and / or combined with at least one image in the visible range, and the tracking means comprises at least one means image processing device for locating at least a portion of the occupant's body from the image captures (s) and also advantageously determining the position of the occupant. The identification of the position of the occupant's body is advantageously used to control the type and location of the thermal source equipment to be activated or adjusted. The invention thus offers a certain flexibility in the implementation of thermal sources in the autonomous vehicle perspective. The invention also relates to a thermal management method implemented by a thermal management system as defined above, the thermal management method comprising the following steps: - acquisition of measurement (s) of at least one usable quantity for determining at least one thermal comfort data representative of the thermal state of at least one occupant of said vehicle, - determining at least one thermal comfort data as a function of said at least one measured quantity, - in according to said at least one determined thermal comfort data, identification of the need to regulate the thermal state of the occupant, characterized in that when a regulation of the thermal state of the occupant is necessary, said method of thermal management further comprises the following steps: - determining at least a first and a second different part of the body of the occu pant on which to act to regulate the thermal state of the occupant, - for each part of the body determined in step, identification of an associated equipment for acting on this part of the body, - control of at least one first actuator configured for adjusting at least one parameter of a first associated equipment capable of acting on the first part of the occupant's body, and a second actuator configured for adjusting at least one parameter of a second associated equipment able to act on the second part of the body of the occupant in a manner differentiated from the first equipment.
    Thus, the thermal management method makes it possible to regulate the comfort of each occupant from a measure of the feeling of comfort, for example through his infrared "signature" (at the level of his head and / or hands) measured. in real time, locally providing heat flows advantageously of different natures on different parts of the body of the occupant.
    According to one aspect of the invention, said thermal management method further comprises a step of acquiring at least one temporal information relating to the use scenario of said vehicle, and takes into account said at least one temporal information for the determination. parts of the body on which to act to regulate the thermal state of the occupant.
    According to another aspect of the invention, control signals for the control of said actuators are generated.
    The control signals SC advantageously comprise at least one location information of the equipment to be controlled.
    According to one embodiment, the control signals comprise at least one power information of the associated equipment.
    According to one embodiment, the control signals comprise at least one predefined delay datum. It can be a predefined duration for the implementation of a given piece of equipment. Alternatively or additionally, it may be a condition of thermal neutrality reached, that is to say that the occupant has neither hot nor cold, for example it can be provided to implement the equipment until the determined thermal comfort data is representative of a state of thermal neutrality of the occupant.
    In particular, the control signals may comprise a combined information including a predefined duration for the implementation of this equipment to a defined power followed by a lowering of the power of this equipment. Alternatively or in addition, it can be expected to lower the power of the equipment when the thermal comfort data determined is representative of a state of thermal neutrality of the occupant. Other features and advantages of the invention will appear more clearly on reading the following description, given by way of illustrative and non-limiting example, and the appended drawings in which: FIG. 1 shows a schematic representation of a thermal management system according to the invention for a motor vehicle, - Figure 2 schematically shows the body of an occupant of the vehicle and the corresponding actuator of the thermal management system to be controlled according to the body part or body area of the occupant of the vehicle, and - Figure 3 shows a schematic representation of the steps of a thermal management process implemented by the thermal management system.
    The identical elements in the different figures bear the same references.
    The following achievements are examples. Although the description refers to one or more embodiments, this does not necessarily mean that each reference relates to the same embodiment, or that the features apply only to a single embodiment. Simple features of different embodiments may also be combined to provide other embodiments.
    In the description it is possible to index certain elements or parameters, for example first element or second element as well as first parameter and second parameter, or first criterion and second criterion, and so on. In this case, it is a simple indexing to differentiate and name elements or parameters or criteria close but not identical. This indexing does not imply a priority of one element, parameter or criterion with respect to another, and it is easy to interchange such denominations without departing from the scope of the present description. This indexing does not imply either an order in time for example to appreciate this or that criterion. The invention relates to the management of thermal comfort in particular in a passenger compartment of a motor vehicle with the aid of a thermal management system 1 for a motor vehicle shown diagrammatically in FIG.
    In known manner, a vehicle comprises several equipment 3, 5, 7, 9 for heat exchange to affect the thermal state of one or more occupants of the vehicle. A passenger or the driver of the vehicle is referred to as the occupant.
    These equipment 3, 5, 7, 9 are also called thermal sources. The term "thermal source" means that these equipment can deliver hot and / or cold in the form of a heat flow.
    These various equipment 3, 5, 7, 9 or thermal sources of the vehicle are generally different in nature, that is to say that they allow heat exchange according to phenomena of different nature involving different thermal flows. By way of example, mention may be made of heat fluxes: convective on the air, radiative, originating from the sun or from radiating surfaces, such as a hot instrument panel or a cold glass, or conductive, coming from surfaces in contact with the occupants of the vehicle, such as a seat or steering wheel. It can thus act closer to the occupant to regulate its thermal state, that is to say if it is hot or cold.
    Thermal management system
    The thermal management system 1 for a motor vehicle comprises: a predefined number of actuators A101, Al02, A103, A104 respectively associated with one or more equipment 3, 5, 7, 9 in the vehicle, a control device 12 actuators A101, A102, A103, A104, and - at least one sensor 13, 113 able to communicate with the control device 12 to allow the control of at least some of the actuators A101, A102, Al03, Al04 according to the measurements of the sensor or sensors 13, 113.
    In the example shown diagrammatically in FIG. 1, four actuators A101 to A104 are represented. Of course more actuators or only two or three actuators can be provided.
    The actuators A101 to A104 respectively act on or control an equipment 3, 5, 7, 9 of the associated vehicle, so as to activate or modify an operating parameter of this equipment 3, 5, 7, 9 to regulate the thermal state of the occupant, specifically a respective associated portion of the occupant's body.
    The actuators A101 to A104 are respectively configured for the adjustment of at least one parameter of an associated equipment 3, 5, 7, 9, this parameter being able to act on the regulation of the thermal state of the occupant. In particular, it is possible to provide at least: a first actuator configured for adjusting at least one parameter of a first associated equipment able to regulate the thermal state of the occupant at a first part of the body of the occupant, and - a second actuator configured for adjusting at least one parameter of a second associated equipment adapted to regulate the thermal state of the occupant at a second part of the body of the different occupant of the first part of the occupant's body.
    At least one or some actuators A104 may allow the adjustment of at least one aerothermal parameter of the air flow in an air conditioning installation, namely heating, ventilation and / or air conditioning of the vehicle (not shown in FIG. the figures). The aerothermal parameters generally used in a ventilation, heating and / or air conditioning installation are the airflow temperature, the humidity rate, the flow rate of the air flow and / or the distribution of the flow of air. air in the cockpit. By way of example, patent FR 2 917 855 describes the thermal management by acting on aerothermal parameters in an air conditioning installation of a motor vehicle.
    In addition, at least one or some actuators A101, Al02, Al03 may allow adjustment of at least one parameter of a device provided in the passenger compartment of said vehicle, such as a window, or a seat 3, or the steering wheel. 5, or a radiant panel 7, so as to regulate the thermal state of the occupant locally at a given part of his body. By way of illustrative and nonlimiting example, with reference to FIGS. 1 and 2: the actuator A101 allows the adjustment of at least one parameter of a seat 3, for example the temperature of the seat 3, which makes it possible to regulate the temperature of the occupant at his back, - the actuator A102 allows the adjustment of at least one parameter of the steering wheel 5, for example the temperature of the steering wheel 5, which regulates the temperature of the occupant at the level of the with one hand or both hands, - the actuator A103 allows the adjustment of at least one parameter of at least one radiant panel 7 or radiator, - the actuator A104 allows the adjustment of at least one aerothermal parameter the heating, ventilation and / or air-conditioning system, for example the outgoing air flow by one or more aerators 9 in a given area or in different places of the passenger compartment.
    The control device 12 is itself able to determine at least one thermal comfort data or thermal sensation TS of the occupant according to the measurements of the sensor or the sensors 13, 113, and able to use the thermal comfort data TS for controlling the actuators A101, A102, A103, A104. More specifically, the control device 12 is able to differentially control at least two actuators among the actuators Al01 to A104, for separately and locally controlling the thermal state at at least two different parts of the occupant's body. .
    The sensor advantageously comprises a thermal state sensor 13 capable of measuring at least one thermal quantity relative to the thermal state of at least one occupant of said vehicle, that is to say a quantity that makes it possible subsequently to define whether the occupant is in a predefined thermal comfort zone, ie in a zone of thermal neutrality for the occupant that is to say that the occupant is neither hot nor cold. The thermal magnitude relates to any magnitude indicative of a thermal sensation, that is to say if the occupant is hot, cold, or is in the thermal comfort zone.
    Advantageously, the thermal state sensor 13 is able to carry out a direct measurement which relates to the occupant himself.
    In particular, the thermal state sensor 13 may measure one or more thermal values related to different body areas or parts of the occupant's body. The various parts of the occupant's body are, for example, the head, or more precisely one or more areas of the face, the nape, at least one shoulder, the torso, the back, at least one hand, at least one arm, the at least one leg, at least one foot and / or one ankle. Thermal values relating to all these body parts or alternatively only to certain body parts can be measured.
    The thermal state sensor 13 is for example an infrared sensor. It is advantageously at least one infrared camera or infrared image capture apparatus or infrared imager.
    According to a preferred embodiment, the sensor 13 makes it possible to carry out an infrared mapping of the occupant's face, in particular by identifying and measuring the temperature of remarkable points such as the nose, the cheeks, the forehead.
    As a variant or in addition, the thermal state sensor 13 may make it possible to carry out an infrared mapping of at least one hand of the occupant.
    As a variant or in addition, at least one camera or imager sensitive to wavelengths located in the visible spectrum can be provided.
    The combination of an infrared imager and an imager in the visible range makes it possible to enrich the data processing. Indeed, an infrared image facilitates the recognition of the parts of the body and the positioning of the body in the visible image. In this case, the two images must be read on each other. The information is then richer than what can be done by one or the other of the imagers.
    With reference to FIG. 1, the signals S (TMS) originating from the thermal state sensor 13 correspond to the measurements of the quantities relative to the thermal state of at least one occupant of the motor vehicle. In the case of an infrared camera or an infrared image capture apparatus or infrared imager, the signals S (TMS) are for example in the form of a sequence of images or an infrared image of a area of the passenger compartment in which the occupant is.
    The thermal state sensor 13 is connected to the control device 12 which is able to process the signals S (TMS). The thermal state sensor 13 may be able to supply the signals S (TMS) to the control device 12. To do this, the thermal state sensor 13 may comprise at least one means for transmitting data to the control device 12 .
    In parallel with measurements of magnitudes relating to the thermal state of the occupant or occupants, other measures are advantageously carried out, in particular relating to the environment of the passenger compartment in which the occupant of the vehicle is moving.
    For this, the thermal management system 1 may comprise at least one sensor of the thermal environment 113 in the passenger compartment.
    The sensor of the thermal environment 113 in the passenger compartment is capable of detecting and / or measuring at least one of the following variables: - the operation of equipment enabling thermal regulation, such as the activation of the heating or cooling function of the seat 3, the activation of the heating function of the steering wheel 5, the operation of one or more radiant panels 7, the temperature of the surface of a device in the vehicle, such as at least one seat 3 or the flywheel 5, or at least one window, - aerothermal parameters such as: • the interior temperature in the passenger compartment, • the air flow observed, • the air distribution observed through the aerators 9, • the orientation air flow, for example if the airflow is directed towards the head of the occupant of the vehicle, - the temperature outside the passenger compartment observed, - a difference in temperature between the interior and the outside of the cabin, - the solar flux, - the observed humidity level, - or other data describing the environment.
    Advantageously, the data relating to the environment of the passenger compartment are differentiated according to the area of the cabin concerned, for example left / right and / or front / rear.
    The sensor of the thermal environment 1 f 3 may be an infrared sensor, in particular it may be the same sensor as the thermal state sensor f3. It is advantageously at least one infrared camera or infrared image capture apparatus. It is possible to envisage a plurality of additional sensors of the thermal environment 113 in addition to the infrared imager for example, so as to better apprehend the thermal environment.
    The or each sensor of the thermal environment 113 is capable of supplying the control device 12 with signals S (PMS). The sensor of the thermal environment 113 is therefore connected to the control device 12.
    The control device 12 advantageously comprises one or more processing means 14 for: - receiving or acquiring the signals S (TMS) supplied by the thermal state sensor 13, and / or for receiving or acquiring the signals S (PMS) supplied by the thermal environment sensor 113, - analyzing the signals S (TMS) and / or S (PMS) to determine at least one thermal comfort data TS of the occupant.
    "Thermal comfort data" is understood to mean a datum for estimating the thermal sensation of the occupant, that is to say whether it is hot, cold, or is situated in the predefined thermal comfort zone or zone thermal neutrality.
    The quantities relating to the thermal state of the occupant and advantageously the characteristics of the thermal environment surrounding the occupant of the vehicle, are used to estimate the thermal comfort data or thermal sensation TS perceived by a person, on the basis of the chosen thermal comfort model including the thermo-physiological model and a model of the environment in the chosen vehicle.
    The thermal comfort data TS is determined, in a modeled manner, using an algorithm operating on the basis of a chosen thermal comfort model comprising at least one thermo-physiological model based on the thermal sensation of a panel. representative of the population whose body temperature was measured under different conditions.
    The model of thermal comfort describes in particular the behavior of the body of the individual when certain conditions are applied, in particular boundary conditions, for example if heat is applied to his back or if a jet of fresh air reaches the level of his face, and therefore the correction to be taken into account at the level of the interpretation of the infrared mapping of his face for example to determine a thermal comfort data TS. From this correction information and information of the environment or the thermal environment in the passenger compartment, the control device 12 can calibrate the measurements, here infrared, that is done preferentially at the level of the face, so that these measurements be exploitable. By way of example, patent FR 2 917 855 describes an example of a thermophysiological model. As described in patent FR 2 917 855, it is possible to take into account the category of thermal sensitivity to which the occupant belongs, namely whether this person has a thermal sensitivity corresponding to the average population or is more sensitive to heat. or cold than the average population. The characteristics of the garments can also be used as described in the patent FR 2 917 855. From the data or thermal comfort data TS, the control device 12 is able to detect if the occupant is in the zone of predefined thermal comfort. To do this, the control device 12 may comprise at least one means for comparing the thermal comfort data TS with predefined reference data or target data. If this is not the case, that is to say that the occupant is outside the thermal comfort zone, for example if it is hot or cold, the control device determines that a thermal regulation of the occupant is necessary.
    In this case, the control device 12 is able to determine parts of the body on which the thermal management system 1 must act.
    Moreover, the control device 12 advantageously comprises, among the processing means 14, at least one means for locating the position of the occupant in the space able to locate at least a portion of the occupant's body in the room. 'space. The locating means is adapted to use the measurements made by the thermal state sensor 13 to locate at least a portion of the occupant's body in the space.
    When the thermal state sensor 13 is a camera or an imager capable of capturing at least one image or sequence of images, the locating means may comprise at least one image processing means capable of detecting various zones of an image. or several image (s) captured (s) by the thermal state sensor 13, and preferably able to also detect the temperatures associated with these identified areas. The image processing means identifies the occupant's position and locates at least a portion of the occupant's body from the captures of the camera.
    In the case of an infrared camera or imager, the hot elements are marked. The use of an infrared camera or imager can advantageously be combined with the use of a wavelength sensitive camera or imager in the visible spectrum to identify and locate the position of the body.
    In the patent FR 2 917 855, an example is provided of global identification in the space of the face of a passenger or driver and deduction of temperatures on the various areas of the face identified. The identification in the space of the face of a vehicle occupant is therefore not detailed again in the present. According to one embodiment, following the registration in the space of the face, it is possible to determine the position of the body. By way of non-limiting example, such a location makes it possible in particular to detect whether the driver has his hands on the steering wheel or whether the driver or passenger has his face turned and in which direction. This information can be used by the control device 12 to determine parts of the body on which the thermal management system 1 must act and to adjust the control commands of one or more equipment 3, 5, 7, 9.
    The thermal management system 1 can also determine a different thermal comfort data TS according to the right or left side of the occupant, for example due to direct exposure to the sun on one of its sides.
    The control device 12 further comprises at least one processing means for identifying, for each part of the body, a device 3, 5, 7, 9 of the vehicle to be controlled for regulating the thermal state of this part of the body and therefore the actuators A101, A102, A103, A104 to be controlled. The control device 12 can then differentially control at least two of the actuators A101 to A104 for the control of the identified equipment so as to regulate the thermal state of the occupant by acting on different parts of the body.
    For this purpose, the control device 12 advantageously comprises one or more processing means 14 for: from the thermal comfort data or data TS, define or generate at least two control signals SC including at least one first signal of controlling a first actuator and at least a second signal of a second actuator, and - transmitting the control signals SC defined in order to differentially control at least two of the actuators A1 01 to A104, for example on respective outputs of the control device 12.
    In the example illustrated in Figure 1, four control signals SCI, SC2, SC3, SC4 are shown schematically. Of course, there may be fewer or more SC control signals.
    When the thermal management system 1 determines different thermal comfort data TS according to the right or left side of the occupant, this information is taken into account by the control device 12 for the definition of the control signals SC, for example for adjust the air temperature for each side or adjust the airflow direction.
    In addition, the thermal management system 1 may comprise at least one acquisition means for determining or recording one or more temporal information t or of sequencing over time of a usage scenario of the vehicle. An example of time information t, if the occupant has just entered the vehicle, how long has the occupant been sitting in the seat, how long has the vehicle been traveling, how long given equipment for thermal regulation, and possibly its orientation, is started.
    It may be a temporal management module of the thermal management system 1. In particular, it may be a processing means 14 of the control device 12. The set of time data t may be taken in account by the controller 12 to define the control signals SC. The control device 12 can take into account whether the occupant has just entered the vehicle or has been in the vehicle for some time to make the choice to control or not certain equipment, such as for example the activation of the heating function 3. In fact, in order to illustrate this point, it is noted, for example, that in winter it is very pleasant for an individual entering a vehicle whose cabin environment is cold, to activate the heated seat at this time. moment, but a heat production at the back of the individual on a long journey is very unpleasant and is therefore perceived as discomfort by this individual.
    The comfort commands that the control device 12 makes it possible to control via the actuators A101, A102, A103, A104 concern, for example: - the activation of the heating function of the steering wheel 5, - the temperature of the steering wheel 5, - activation of the heating or cooling function of the seat 3 on which the occupant is located, the temperature of the seat 3, the activation of one or more radiant panels 7, the activation of a heating function of one or more windows in the passenger compartment, - the temperature of one or more windows in the passenger compartment, - the adjustment of the opacity / transparency of one or more electrochromic windows in the passenger compartment, - the temperature of the pulsed air towards the passenger compartment, - the moisture content of the air pulsed towards the passenger compartment, - the air flow, - the distribution of pulsed air in the passenger compartment through the various aerators 9, - a percentage of recirculation of the air, in other words the distribution between new outside air and recirculating air coming from the passenger compartment, - distribution of hot air / cold air in the pulsed air to the passenger compartment, - speeds of the various motor-fan units used within the vehicle. the heating, ventilation and / or air conditioning system.
    Examples of realization:
    Thus, for a thermal comfort data TS indicating that the occupant is not in the predefined thermal comfort zone, the thermal management system 1 can implement actions intended to regulate the thermal state of the occupying different parts of his body, for example for a predetermined duration and / or until the thermal comfort data TS indicates a neutral state. In other words, the thermal management system 1 provides so-called positive stimuli to different parts of the occupant's body.
    In particular, thermal sources acting on different segments or parts of the body of the occupant may be of different natures: for example convection on his head, radiation on his chest, contact on his hands and back. This has the effect of using other vectors than air to focus the thermal regulation on certain parts of the occupant's body. As an illustrative and nonlimiting example, for a thermal comfort data TS indicating that the occupant is hot, the thermal management system 1 can implement actions to refresh the occupant in different places of his body.
    For example, the thermal management system 1 may control an actuator A104 to engage an air jet to cool the occupant by convection at his head. The thermal management system 1 can also control the actuator A101 to activate the cooling function of the seat 3 on which the occupant sits to cool the occupant by contact at his back. In parallel, the thermal management system 1 can turn on the air conditioning for the cooling of the air intended for the habitable.
    In another example, for thermal comfort data TS indicating that the occupant is cold, the thermal management system 1 can implement actions for the purpose of heating the occupant in different parts of his body. For example, the thermal management system 1 can control the actuator Al03 to engage at least one radiant panel 7, to heat by radiation for example the torso of the occupant. The thermal management system 1 can also control the actuator A101 to activate the heating function of the heating seat 3 on which the occupant sits to heat the occupant by contact at his back. The thermal management system 1 can still control the actuator A102 to activate the heating function of the steering wheel 5 to warm the occupant by contact at his hands. In parallel, the thermal management system 1 can trigger the heating of the air intended for the habitable.
    Alternatively or in addition, if the thermal management system 1 determines a different thermal comfort data TS depending on the side, the control device 12 controls the actuators so as to adjust the thermal comfort between the two sides.
    It is therefore understood that, depending on the value of the thermal comfort data or data TS, data of the cabin environment such as in particular the interior temperature of the passenger compartment and the temperature outside the passenger compartment, and advantageously of temporal data, in particular reflecting a temporal sequencing of a use scenario of the vehicle, if the user has just entered the vehicle for example, the thermal management system 1 can control at least two pieces of equipment to act in a differentiated manner on two or more parts different from the occupant's body. This brings positive stimuli located on several parts of the body of the occupant thus allowing the occupant, especially in a transient situation, to wait until the passenger reaches a temperature of comfort. Indeed, it reduces the feeling of discomfort of the occupant by acting closer to him using different thermal sources, by contact, radiation or convection, and not simply by acting on the air of his environment.
    The thermal management system 1 can thus play on the temperature of the seat, the temperature of the steering wheel, the opacity or the transparency of a glazing, the temperature of a glazing the orientation / the opening / closing of end caps air vents placed on the dashboard or at the rear of the motor vehicle, the opening or closing of shutters of ventilation ducts, the stopping or the ignition of a thruster of air conditioning, on the air flow, on a heating device of the heating, ventilation and / or air-conditioning system or on the proportion of air recycled or coming from the air outside. The thermal management system 1 according to the invention thus makes it possible to combine different technologies to regulate the thermal state of the occupant.
    The thermal management can be done automatically, in particular the choice of the equipment on which it is necessary to act and therefore the choice of the associated actuators without requiring the intervention of the occupant. Of course, the possibility can be provided for the occupant to choose or modify at least one given parameter for example via a human-machine interface. The occupant can in particular adjust a setting according to its thermal sensitivity.
    Finally, the thermal management system 1 may have a so-called degraded operating mode, especially in the case where the thermal management system 1 can not perform at least some of the measurements necessary for the prediction of a thermal comfort data TS of the invention. occupant. This degraded mode of operation can be based on a statistical predictive model which allows a default setting of at least two devices for example according to the external conditions. With this degraded mode, one can also provide the possibility that the occupant chooses or modifies at least one given parameter.
    Thermal management method The invention also relates to a thermal management method implemented by a thermal management system 1 for a motor vehicle as defined above.
    With reference to FIG. 3, the thermal management method comprises various steps E10 to E62 described below.
    The thermal management method comprises in particular a step E10 acquisition measurement (s) of one or more thermal values relating to the occupant, for example respectively related to a part or body area different from an occupant of the motor vehicle. This acquisition step E10 is, according to the embodiment described, carried out by the thermal state sensor 13.
    According to a preferred embodiment, the step E10 is a step of capturing at least one image or sequence of images in the infrared spectrum and / or in the visible spectrum.
    It is possible to provide a signal transmission step S (TMS) corresponding to the measurements of the thermal quantities relating to the thermal state of the occupant made, for example, by the thermal state sensor 13.
    The thermal management method may furthermore comprise a step Eli of acquisition of measurement (s) relative to the thermal environment of the environment of the occupant. This acquisition step Eli can be performed by the same device as for step E10, such as an infrared imager, and / or by one or more other sensor (s) of the thermal environment in the interior 113.
    It is possible to provide a signal transmission step S (PMS) corresponding to the measurements of the thermal quantities relating to the environment made, for example by the or each sensor of the thermal environment in the passenger compartment 113.
    The thermal management method advantageously also comprises a step E12 of acquiring at least one temporal information l concerning the use scenario of the vehicle, for example without limitation if the occupant has just entered the vehicle or since how long is he in the vehicle. This step E12 of acquiring at least one temporal information t can be performed by a temporal management module of the thermal management system 1, in which case the time information or t can be transmitted to the control device 12. this step E12 of acquiring at least one temporal information t can be carried out by at least one processing means 14 of the control device 12.
    The thermal management method further comprises a step E20 of determining at least one thermal comfort data TS of the occupant according to the measured quantities. These include the quantities relating to the thermal state of the occupant of the vehicle measured by the thermal state sensor 13. In addition, it may also be the quantities relating to the thermal environment measured by the the sensors of the thermal environment 113.
    For this, the determination step E20 comprises at least: a substep of receiving or acquiring the signals S (TMS) and / or S (PMS) for example by the control device 12 of the thermal management system 1, - a substep of processing and analysis of signals S (TMS) and / or S (PMS), in order to determine at least one thermal comfort data TS relative to the occupant.
    According to a preferred embodiment, step E20 comprises a substep of analyzing an image or sequence of images and locating remarkable points for example of the occupant's face to identify the temperature at these levels. remarkable points.
    Advantageously, the step E20 comprises a substep of locating the body of the occupant in the space.
    Advantageously, the step E20 comprises a substep of determination of the position of the occupant in the vehicle, for example the orientation of the face of the occupant or if the driver has one or both hands on the steering wheel.
    During a step E30, the thermal management method makes it possible to identify whether the occupant requires thermal regulation from the thermal comfort data TS or determined in step E20, for example by comparing the or each data item. thermal comfort TS to a reference datum or predefined target.
    When thermal regulation is necessary, the thermal management method determines in step E40 at least two parts of the body of the occupant on which to act.
    For the determination of the parts of the occupant's body on which it is necessary to act locally, the thermal management method advantageously takes into account the position of the occupant in the vehicle.
    The thermal management method also advantageously takes into account all the temporal information t concerning the use scenario of the vehicle. In step E50, the thermal management method identifies, among the equipment in the vehicle, the associated equipment to be controlled to act on each part determined in step E40. In particular, the thermal management method identifies at least a first equipment associated with a first part of the body of the occupant, and at least a second equipment associated with a second part of the body of the occupant. The identified equipment is advantageously thermal sources of different nature.
    Once the equipment to be controlled identified, the thermal management method makes it possible to generate or define control signals SC for the actuators respectively allowing the control of these equipment. These control signals SC are configured for adjusting at least one parameter of at least two pieces of equipment of the vehicle according to the thermal comfort data or data T S of the occupant.
    The control signals SC advantageously comprise at least one location information of the equipment to be controlled.
    The control signals SC may also include at least one power information of the equipment to be controlled.
    For the definition of the control signals SC, the thermal management method advantageously takes into account the position of the occupant in the vehicle, in order to adjust the adjustment of the equipment according to this position of the occupant. By way of nonlimiting example, if the occupant has his head turned in a certain direction, a control signal SC4 is sent to an actuator A104 to control the orientation of the air flow through a given aerator 9.
    Thus, in a step E61, at least a first control signal is defined and sent to a first actuator configured for adjusting at least one parameter of a first associated equipment capable of regulating the thermal state of the occupant at the level of a first part of the occupant's body.
    In a step E62, at least one second control signal is defined and sent to a second actuator configured for adjusting at least one parameter of a second associated equipment capable of regulating the thermal state of the occupant at the level of a second part of the occupant's body different from the first part of the occupant's body.
    This makes it possible to differentially regulate the thermal state of the occupant at different parts of his body.
    According to one embodiment, the control signals SC may comprise at least one predefined delay datum. By way of nonlimiting example, the local action on a given part or body area by activating or adjusting an associated equipment can be implemented for a predefined duration. According to another example, after a predefined period, the power of one or more given equipment is lowered.
    Alternatively or additionally, the timing data may include an achieved thermal neutrality condition, ie local action on a given body part or zone of the occupant by activating or adjusting an associated equipment may last until that the occupant is in the predefined thermal comfort zone. In this case, steps E10 to E20 can be performed in parallel with steps E61, E62.
    In another example, the power of one or more given equipment is lowered when the occupant is in the predefined thermal comfort zone.
    Of course, the order of at least some steps of this thermal management method can be reversed.
    Thus, it is possible to carry out a thermal management method for which one or more measuring means or sensors 13, 113, in particular infrared, may be used, and in which the measurements made by these sensors 13, 113, are used to define the control signals SC sent to the actuators A101,..., Al04, of equipment in the passenger compartment or of the heating, ventilation and / or air-conditioning system, so as to act in a differentiated manner on different segments of the body of the occupant according to the thermal comfort data TS of the occupant determined.
    An advantageous management of comfort is to combine and chain the application of thermal flows in a localized way on different parts or body areas of the occupant and the overall management of the temperature in the cabin, to ensure the best feeling possible comfort in different phases of use of a vehicle.
