    The invention relates to a method for managing the quality of air in a motor vehicle. The invention also relates to an air quality management system for the implementation of such a method, as well as to a motor vehicle comprising such an air quality management system.
    Air pollution is increasingly problematic on a global scale and such pollution is particularly noted by motorists during their journeys.
    To give just a few examples, motorists may be confronted with the inconveniences caused by burning fumes, unpleasant odors in tunnels, or fumes in the vicinity of industrial sites or pig farms, but also more harmful pollutants such as unburned motor hydrocarbons or carcinogenic derivatives formed, such as benzene products, carbon dioxide and carbon monoxide.
    Drivers also experience more general local environmental elements such as the presence of excessive concentrations of ozone, nitrogen oxides, sulfur dioxide or other compounds in the atmosphere and related to climatic and urban conditions. . The presence of pollen, dust and various allergenic elements can also cause inconvenience to many people.
    When a vehicle crosses a polluted zone, it is desirable to have the level of air pollution in this zone, in order to adapt accordingly the operation of the equipment of the vehicle which acts on the quality of the air entering the zone. cabin, such as air purification devices, air blowers or the air intake flap of the vehicle.
    In existing embodiments, a pollution sensor is used to adapt the operation of a vehicle equipment. It is known, in particular to adapt the position of a vehicle air intake flap which controls the outside air inlet and the recirculated air intake of an inlet housing. air to send into the cockpit either an outside air flow, a recirculated air flow or a mixture of outside and recirculated air, depending on the aerothermal comfort and / or the required air quality in the cockpit. It is also known to immediately close any opening of the vehicle which would be in the open position when passing through the polluted area.
    However, when an unacceptable level of external pollution is detected, it is usually too late for switching the position of the air intake flap from the "outside air" position to the "recirculated air" position. Or closing the cabin vis-à-vis the outside atmosphere effectively protects the passengers of the vehicle. Outside pollution may already be trapped inside the vehicle when an action to prevent contamination of the vehicle cabin air is undertaken. The invention therefore aims to at least partially overcome this disadvantage of the prior art by providing an air quality management method for reliably protecting the occupants of a vehicle against external pollution, when this vehicle crosses a polluted area. To this end, the present invention relates to a method for managing the quality of air in a motor vehicle, comprising the following steps: acquisition of at least one piece of data representative of the quality of the air in a perimeter selected around said vehicle, for example up to 300m, said at least one data representative of the air quality comprising at least one location information, identification of the presence of at least one pollutant, detection of a higher outdoor pollution level to a predefined associated threshold.

The invention relates to the management of the air quality, within one or more vehicles V2, taking into account information collected by one or more vehicles VI upstream and / or by a server 100, as shown in FIG. schematic in Figures la to 2. In the present, "upstream" and "downstream" are defined with respect to the direction of circulation of the vehicle V2 in which the air quality management process is at least partially implemented , in other words, in the vehicle V2 concerned with the management of the quality of the air.
    In order to distinguish the vehicle V2 in which the air quality management method is at least partially implemented from the other vehicles discussed herein, this vehicle V2 is subsequently designated by reference vehicle V2. The invention relates more particularly to an air quality management method shown diagrammatically in FIG. 3, which can be implemented by an air quality management system represented in a simplified manner in FIG. 4.
    With reference to FIGS. 1a-2, the air quality management system 1 can be loaded onto the reference vehicle V2 in which the air quality management method is at least partially implemented. For example, the air quality management method is implemented when the on-board air quality management system 1 is activated.
    Alternatively, the air quality management system 1 can be connected to this reference vehicle V2. For example, a telecommunications device A such as a smartphone or smartphone phone in English, or a tablet or a computer, connected to the reference vehicle V2 may include the air quality management system 1 or the least certain means of processing this system 1. This telecommunication apparatus A may be located inside the reference vehicle V2.
    The air quality management method is for example implemented when a dedicated application is launched on the apparatus A.
    With reference to FIGS. 1a to 3, the air quality management method comprises a first acquisition step E1 of at least one datum or set of data representative of the quality of the air in a perimeter chosen around the reference vehicle V2. As a non-limitative example, the perimeter can be chosen up to 300m. For this purpose, the or each data representative of the air quality advantageously comprises at least one location information, for example geolocation coordinates commonly designated by the acronym GPS in English.
    For example, the data or data set relates to the concentration of one or more pollutants p.
    With reference to FIGS. 1a to 4, the data or data representative of the quality of the air come from a monitoring device 3 external to the reference vehicle V2 in which the air quality management method is at least partially implemented. The term "external" means that the monitoring device 3 whose measurements are used to implement the method within the reference vehicle V2 does not belong to the reference vehicle V2, this monitoring device is outside the reference vehicle V2 that is to say, it is neither inside the reference vehicle V2 nor on the outside of the vehicle V2.
    According to an exemplary embodiment, the data d representative of the quality of the air comes from a monitoring device 3 provided on a motor vehicle VI upstream with respect to the direction of circulation of the reference vehicle V2 and located in the chosen perimeter.
    In order to allow the implementation of the air quality management method, the air quality management system 1 of the reference vehicle V2 comprises at least one means of communication with at least one other motor vehicle VI upstream located in the perimeter chosen and comprising a monitoring device 3 of the air quality. It may be inter-vehicle communication means provided on the vehicles VI, V2, as a non-limiting example for communication over Wi-Fi or Bluetooth or any other means or appropriate communication protocol.
    Figures la and lb show schematically two vehicles VI, V2 able to communicate with each other. For this purpose, the monitoring device 3 of the upstream vehicle VI comprises at least one measuring means such as a pollution sensor capable of detecting the presence of one or more pollutants p in the air. The sensor or sensors may be located outside the cabin of the upstream vehicle VI to detect the level of outdoor pollution.

Pollutant is also understood to mean any material that is toxic to humans but also generates olfactory nuisances or allergies.
    The monitoring device 3 of the upstream vehicle VI further comprises at least one processing means for determining or delivering at least one data representative of the quality of the air, from the measurements of the or each pollution sensor. In particular, the pollution sensor may be able to deliver itself one or more data representative of the quality of the air.
    The monitoring device 3 of the upstream vehicle VI further comprises at least one means for transmitting one or more data, including at least one datum representative of the quality of the air. The upstream vehicle VI can in particular transmit a plurality of data d representative of the air quality at predefined time intervals, in particular at regular time intervals.
    As a variant or in addition, the data or d representative of the air quality come from an associated server 100 as schematized in Figures 1a and 1d. This may be a server 100 collecting real-time information concerning the quality of air transmitted by air quality monitoring bodies and / or transmitted by a plurality of vehicles for example using a service. and / or an application relating in particular to the control and monitoring of air quality.
    This server 100 includes at least one database collecting data representative of the quality of the air.
    Advantageously, the server 100 can send the relevant data concerning the quality of the air to all the vehicles VI, V2, V3 which are in a predefined zone with respect to the location of the external pollution based on the information of location such as geolocation coordinates associated with data representative of air quality and geolocation coordinates of vehicles to which data must be transmitted or not d.
    In this case, in order to allow the implementation of the air quality management method, the air quality management system 1 of the reference vehicle V2 comprises at least one means of communication with the server 100 .
    According to yet another exemplary embodiment, the data representative of the quality of the air can come from at least one apparatus A 'situated in the chosen perimeter of the reference vehicle V2, for example located in a vehicle V3 neighboring the reference vehicle V2 as shown schematically in Figure 2. The device A 'may be a telecommunications device such as a smartphone said phone or "smartphone" in English, or a tablet or computer. In order to enable the implementation of the air quality management method, this apparatus A 'comprises means of communication with one or more upstream vehicles VI as defined above and / or with the server 100 described above, and means of communication with the reference vehicle V2 in which the air quality management method can be implemented. In this case, the apparatus A 'situated in the vicinity of the reference vehicle V2 is capable of acquiring one or more data d representing the quality of the air in the chosen perimeter and is able to transmit these data to the management system. of the air quality 1 of the vehicle V2.
    Of course, the vehicles V2, V3 shown diagrammatically in Figures la to 2 may also include one or more monitoring devices including in particular at least one pollution sensor, but in this case the data recorded by these monitoring devices which are representative of the air quality are advantageously used by vehicles downstream of these vehicles V2, V3 according to the direction of circulation of these vehicles downstream in which the air quality management process can be at least partially implemented.
    Referring again to FIGS. 1a to 4, the air quality management system 1 comprises, for its part, at least one processing means 5 for acquiring the or each data item representative of the quality of the air in a perimeter chosen around the reference vehicle V2 in step E1. This processing means 5 is based, for this purpose, on the location information such as the GPS location coordinates associated with the external pollution information transmitted in the data. representative of the quality of the air.
    A plurality of data representative of the quality of the air can be acquired at predefined time intervals, in particular at regular intervals of time.
    The processing means 5 for acquiring is for example a means for receiving the data or data transmitted by one or more vehicles VI upstream, more precisely by the monitoring device 3 of one or more vehicles VI upstream. As a variant or in addition, it may be a means of communication of the reference vehicle V2 with the server 100 or a device A 'nearby, able to receive or search the data representative of the quality of the air in the perimeter chosen around the reference vehicle V2 among the set of data available at the level of the server 100 or the apparatus A 'nearby.
    The or each relevant data item can be stored in a memory 1 of the air quality management system 1. The storage can be temporary for a predefined time interval in which one or more means of processing the management system. air quality can use the stored data.
    For example, in the case of a plurality of data representative of air quality acquired, the method may comprise a step of crossing the data, such as a step of calculating an average of the concentration of a pollutant. . For this purpose, the air quality management system 1 may comprise at least one processing means for crossing the plurality of data d representative of the quality of the air, such as a calculation means.
    According to another example, the method may comprise a step of weighting all the data d representing the quality of the air, as a function of the distance from the reference vehicle V2 based on the location information such as than geolocation coordinates. For this purpose, the air quality management system 1 may comprise at least one processing means, such as a calculation means, for weighting the data d as a function of distance from the reference vehicle V2 .
    Referring again to FIGS. 3 and 4, during a second step E2, the method makes it possible to identify the presence of at least one pollutant p. For this purpose, the air quality management system 1 advantageously comprises at least one treatment means 9 for detecting the presence of one or more pollutants p from the data or data representative of the quality of the air. the air.
    The method allows in a third step E3, to detect an external pollution level np greater than a predefined associated threshold, that is to say an external pollution level np considered unacceptable.
    According to a preferred embodiment, this step E3 for detecting an unacceptable level of external pollution np is carried out within the reference vehicle V2 in which the air quality management action is intended to be implemented. artwork.
    Advantageously, the air quality management system 1 comprises a memory 72, which may be different or the same as for the storage of the data d, in which one or more predefined thresholds are recorded. Each threshold s is defined according to each pollutant p that can be detected by the monitoring device or devices 3. In other words for each pollutant p, an associated threshold s is predefined.
    The threshold s for the level of external pollution associated with a given pollutant p and to trigger the action of air quality management is advantageously specific to each motor vehicle manufacturer, or even to each range of vehicle.
    This threshold s for the outdoor pollution level may also be specific to each vehicle depending on user settings. Of course, it can be provided that the or each threshold s of outdoor pollution, can be adjusted by the user of the reference vehicle V2, in particular according to its own perception with regard to olfactory and / or skin nuisance. Preferably, the user of the reference vehicle V2 can adjust the threshold 5 by cracking this threshold 5, so as not to degrade the performance specified by the car manufacturer in particular. This is particularly interesting when the user wants to adapt the management of the air quality with respect to allergies that are specific for example.
    For this purpose, it is possible to provide a human machine interface comprising a control member such as an adjustment knob enabling the user to adjust the threshold or s respectively associated with a given pollutant p. It could also be envisaged that the threshold s of the level of external pollution to be considered for a given pollutant p is transmitted by a server, for example the server 100.
    Moreover, the air quality management system 1 comprises at least one treatment means 9, 11 for: determining the level of external pollution np associated with the pollutant p or with each pollutant p identified in step E2 and to - detect whether the or each level of external pollution np is greater than or not the predefined threshold s associated with it. For this purpose, it is possible to provide at least one comparison means 11 for the or each level of external pollution np at the predefined associated threshold s.
    According to a variant not shown, it can be envisaged that the identification steps E2 of a given pollutant p and detection E3 of an unacceptable level of external pollution np linked to this identified pollutant, are carried out externally to the reference vehicle V2 , for example at the level of the monitoring device 3 of the upstream vehicle (s) V1. This information may be transmitted by the upstream vehicle (s) V1 in the air quality representative data or data to the air quality management system 1 of the reference vehicle V2 downstream, or may be available in the server 100.
    This would be particularly advantageous for vehicles of the same brand for which the different thresholds s predefined associated pollutants p that we can meet are the same.
    When an external pollution level np greater than an associated threshold s predefined is detected, the method further comprises at least one step E4 triggering in said reference vehicle V2 an action of air quality management.
    In particular, if the presence of several pollutants is detected, the air quality management action can be triggered at step E4 when at least one external pollution level np relating to a given pollutant p exceeds predefined associated threshold value s.
    This action of air quality management aims to adapt the operation of one or more equipment acting on the air quality.
    To do this, the air quality management system 1 comprises at least one processing means 13 for triggering in the reference vehicle V2 the air quality management action, when a pollution level external np greater than the predefined associated threshold s is detected. Advantageously at least one processing means 13 is able to define one or more control signals and able to transmit it (s) to at least one control means 15 of one or more equipment of the reference vehicle V2 enabling act on air quality, that is to say, to implement at least part of the air quality management action. Thus, the air quality management system 1 is connected to one or more equipment control means 15 of the reference vehicle V2 so as to automatically engage the air quality management action. when the reference vehicle V2 advances towards a polluted zone and therefore when a level of external pollution np higher than the predefined associated threshold s is detected, so as to minimize the exposure of the user to pollutant pollution. For example, the air quality management action may comprise at least one step of switching the air intake in a mode of recirculation of the flow of air from the passenger compartment, when the air intake was in an intake mode of fresh air from outside or partially recirculated air that is to say a mixture of fresh air and recirculated air . In other words, in a reference vehicle V2 comprising a heating, ventilation and / or air conditioning system with recirculation of the flow of air from the passenger compartment, using a recirculation flap, the action of air quality management includes at least one control of the recirculation flap so as to close the intake of fresh air from outside the vehicle and open the recirculating air intake from the cockpit. In this case, the processing means 13 is able to define at least one switching control signal in recirculation mode and closure of the recirculation flap. The processing means 13 is then able to transmit this control signal to the control means 15 of the recirculation flap provided in the heating, ventilation and / or air conditioning system of the reference vehicle V2.
    Alternatively or in addition, the air quality management action may comprise at least one step of activating an odor neutralization means, for example a diffuser or a perfume injection means or deodorizing agents in the air flow to the passenger compartment or in the air circuit before delivery into the passenger compartment, so as to improve the quality of the air. In this case, the processing means 13 makes it possible to define at least one start control signal of an odor neutralizing means and / or an air purification device and to transmit this signal of command by means of control 15 adapted to control the odor neutralizing means and / or the air purification apparatus of the reference vehicle V2.
    Alternatively or in addition, the air quality management action may comprise at least one step of activating an air purification apparatus, for example an air ionizer, so as to improve the quality of the air. In this case, the processing means 13 makes it possible to define at least one start-up command signal of an air purification apparatus and to transmit this control signal to the control means 15 able to control the apparatus. of air purification of the reference vehicle V2.
    Alternatively or additionally, the air quality management action may comprise at least one step of modifying the air circuit so that the flow of air passes through at least two filtration levels. For this purpose, a second air circuit may be provided, forcing the air to pass through a second level of filtration, in addition to a first level of filtration advantageously provided in the first air circuit in normal operation. The second level of filtration can be provided in the air inlet or alternatively in the heating, ventilation and / or air conditioning system. In this case, the processing means 13 is able to define at least one control signal for bypassing the first air circuit to pass through the second air circuit and capable of transmitting this bypass control signal by means of corresponding order 15.
    According to another variant embodiment, an additional filtration module (not shown in the figures) can be arranged in the passenger compartment of the reference vehicle V2. For example, the additional filtration module (not shown in the figures) can be arranged on the ceiling or on the rear shelf in the passenger compartment of the reference vehicle V2. In this case, the air quality management action may comprise at least one activation step of the additional filtration module. By way of nonlimiting example, the first level of filtration may comprise a particulate filter and / or a combined filter, that is to say a filter which processes both the filtration of particles or microparticle and the filtration of particles. gas and / or odor. Such a combined filter is conventionally called an activated carbon filter. This is in particular a so-called multi-layer filter, that is to say comprising several layers for filtering different particle sizes, in particular from the largest to the finest particles, and comprising for example in an intermediate layer of activated carbon grains that have the property of adsorbing certain gases and / or odors.
    Similarly, by way of non-limiting example, the second level of filtration or the additional filtration module may comprise at least one of the following filters: a fine particle filter, an activated carbon filter, an anti-allergen filter, an antibacterial filter, an antivirus filter.
    Alternatively or in addition, the air quality management action may comprise at least one step of closing at least one opening of the vehicle if the door is in an open position when a level of external pollution. np greater than the associated predefined s threshold is detected. In this case, the processing means 13 is able to define at least one closing control signal of one or more openings of the vehicle, such as a sunroof and / or a window, and to transmit this control signal to the vehicle. control means 15 of each opening concerned able to move the opening motorized between open positions and a closed position.
    When the reference vehicle V2 crosses the polluted zone, the user is then in an environment protected from the outside, more specifically from outside pollution.
    In addition, it is possible to provide an alerting step by means of an indicator light and / or an audible signal for the automatic implementation of the air quality management action when a level of external pollution np which does not is not eligible is detected. The air quality management action can be implemented for a predefined duration. This predefined duration may be dependent on the level of external pollution np detected.
    According to a preferred embodiment, once the pollution zone is crossed, that is to say that the external pollution level np is lower than the predefined associated threshold s, it is possible to stop at step E5 of the action of air quality management when implemented.
    Alternatively, the air quality management method may include a step of controlling the indoor pollution rate with respect to a second predefined threshold, and the air quality management action is stopped when the indoor pollution rate reaches this second predefined threshold. In fact, the internal pollution rate is due to the release of carbon dioxide, CO2, by the occupants of the reference vehicle V2, in particular in a recirculated air intake situation only in the passenger compartment of the reference vehicle V2, by example due to a management action of the air quality of the air intake switching in the recirculation mode. The step of controlling the indoor pollution rate advantageously comprises the following sub-steps: - measurement of the indoor pollution rate, for example using detection means or pollution sensors arranged in the reference vehicle V2, and - comparison the indoor pollution rate recorded at the second predefined threshold.
    Consequently, according to one or the other of these variants, the processing means 13 of the air quality management system 1 are able to define a stop signal and to transmit this signal. stopping the control means (s) 15 to stop the implementation of the equipment triggered in step E4.
    According to one embodiment, it is possible to further provide a step of restoring the conditions in the reference vehicle V2, such as before triggering the air quality management action. This is particularly advantageous when the user having left the polluted area, wishes to find the comfort of use of before. For this purpose, the reference vehicle V2 may comprise a memory (not shown) for storing the settings in the vehicle V2 before switching on the air quality management action in step E4. In this case, the control means 15 is able to control the different devices to find the stored settings when the external pollution level np is again below the associated threshold s predefined.
    The advantages of the method and of the system according to the invention which make it possible for a user of a reference vehicle V 2 to pass comfortably without polluting the polluted areas, by acting automatically on the quality of the air before entering the vehicle, are thus understood. in the polluted area with real-time data upstream on the road.
