    DEVICE FOR CLEANING A SENSOR OF AN OPTICAL DETECTION SYSTEM FOR A MOTOR VEHICLE
    The field of the present invention is that of optical detection systems, especially used for driving assistance of motor vehicles, which implement optical sensors. In this field, the invention relates more particularly to devices for cleaning the sensors of these optical devices.
    An optical sensing system is any system comprising optical sensors, such as cameras, laser sensors (commonly called LIDARs), or other sensors based on the emission and / or detection of light in the visible or invisible spectrum. 'Man, especially the infrared.
    Such optical detection systems equip an increasing number of motor vehicles to assist the driver of the vehicle in certain driving situations, one of which, well known, is the parking aid. For this aid to be as effective as possible, the data provided by the optical detection system must be of the best possible quality, and it is therefore essential to have clean optics to perform these data acquisitions. To do this, it is known to place, in the vicinity of these optical sensors, a cleaning device capable of projecting a cleaning fluid just before the detection is carried out.
    Such sensors being, most often, concealed from the direct view of the driver of the vehicle, their cleaning is controlled automatically, for example with a predefined periodicity. The problem that arises then is the moment at which this cleaning operation will be carried out, and it may happen that it takes place at a disadvantageous time with regard to a particular driving situation. It is easy to understand, for example, that it is inappropriate for a cleaning operation of the lens of a parking aid camera to be controlled at the moment when the driver is in the process of parking maneuvers or engages a reverse gear.
    If, in the case of a parking aid, the inconvenience may be a simple inconvenience, there are cases in which, depending on the type of sensor considered, the impromptu triggering of a cleaning operation of that it can lead to a potentially accidental driving situation. Moreover, and especially in the case of an automatic trigger cleaning while the vehicle is traveling at high speed, there is a risk that drops of the cleaning liquid is projected into the driver's field of vision and that this represents a dangerous distraction for driving the vehicle.
    The purpose of the present invention is in this context and it proposes a solution in which the cleaning of a sensor of such an optical detection unit can not be started impromptu or in a manner that can lead to a potentially accidental driving situation.
    For this purpose, the subject of the invention is a device for cleaning a sensor of an optical detection system for a motor vehicle, which comprises a fluid distribution assembly on said sensor controlled by operating instructions issued by a module. control. According to the invention, the control module is configured to generate an information message relating to the need for a sensor cleaning operation and to receive a control command from a vehicle occupant authorizing this cleaning operation.
    Thus, the invention proposes that the start of a cleaning operation of such a sensor is subject to prior authorization from the driver of the vehicle.
    According to various features of the invention, taken alone or in combination, provision may be made for: the device comprises means for detecting the presence of foreign bodies on the sensor, which are configured to transmit relative data to the control module; if necessary, a cleaning operation of the optical sensor; - The control module is configured to communicate with signaling means, capable of generating said information message in the passenger compartment of the vehicle; the device comprises means for recognizing the command instruction of a vehicle occupant, configured to communicate with the control module and to transmit to it data relating to the authorization of the cleaning operation; the recognition means are made active by the control module simultaneously with the transmission of said information message; - The recognition means comprise a button adapted to be actuated by an occupant of the vehicle; the recognition means comprise gestural and / or vocal recognition means; the fluid dispensing assembly is configured to move between a rest position and a working position in which the cleaning fluid is dispensed on a surface of the sensor; the device comprises means for monitoring one or more vehicle driving parameters configured to generate data representative of the driving situation of this vehicle and to communicate this data to the control module; - The control module is configured to generate, following a control command of the occupant of the vehicle, several cleaning cycles by the fluid distribution assembly, successively or at predefined time intervals; - The control module is configured to generate, following a control command of the occupant of the vehicle, one or more cleaning cycles until the complete stop of the vehicle.
    In practice, the cleaning device of a sensor of an optical detection system is often coupled to a device for cleaning at least one front and / or rear glazing surface of the vehicle. According to the invention, in this case, the control module may be configured to further control the operation of a cleaning assembly of at least one front and / or rear glazed surface of the vehicle. A common fluid storage tank may be provided with the cleaning assembly of at least one glazed surface and may be provided means for monitoring a fluid level in this tank, configured to communicate with the control module. Furthermore, it can be provided that the control module comprises means for selectively controlling, according to a first predetermined value of fluid level in the storage tank, the cleaning device of the optical sensor and / or the set of cleaning at least one glazed surface.
    In other words, in this case, the cleaning of the sensor of the optical detection system can be controlled alone, in priority with respect to the cleaning of the front and / or rear glazed surface (s) of the vehicle. In this case, according to an advantageous characteristic of the invention, the control module is configured to allow the display, in the cockpit, of a message representative of the fluid level in the storage tank and the operation of cleaning done. The invention also relates to a motor vehicle comprising an optical detection system and an associated cleaning device capable of cleaning the optical sensor of this detection system. It will be possible in particular to provide that the control module is disposed anywhere in the vehicle while the signaling means and the recognition means as previously presented are arranged in the passenger compartment of the vehicle. The invention also relates to a method for cleaning a sensor of an optical detection system for a motor vehicle, in which a fluid distribution assembly is moved between a rest position and a working position in which the fluid can be distributed on a surface of the sensor, during which a detection step is provided on this surface of the sensor, of possible soiling, a step of generating a signal representative of the presence of any soiling on the surface of the optical sensor , a step of displaying, in the cabin of the vehicle, a message representative of the presence of any dirt on the surface of the optical sensor, a step of recognizing a command, by a user located in the passenger compartment of the vehicle, on the basis of the message displayed in the passenger compartment, allowing a cleaning operation of the sensor, and a step of starting the distribution assembly of the vehicle. fluid.
    According to particular features of this method according to the invention, provision may be made for: a step of generating a datum representative of the driving situation of the vehicle, said step of starting up the fluid distribution assembly being conditioned by the value of this data, and / or - a step of monitoring the level of a common reservoir for storing a fluid for cleaning a front and / or rear glazed surface of the vehicle and for cleaning the sensor, and a step of generating a data representative of this fluid level in the storage tank, said step of starting the fluid distribution assembly being conditioned by the value of this data. Other features, details and advantages of the invention will emerge more clearly on reading the description given below as an indication in relation to the appended figures, in which: FIG. 1 is a general schematic view of a cleaning device according to the invention; FIG. 2 is a diagrammatic view, in the form of a flowchart, of a cleaning method according to the invention; and FIG. 3 is a diagrammatic view, in the form of a flowchart, of an alternative cleaning method according to the invention. The invention will be described in the following in its non-exclusive application to an optical detection system comprising an optical sensor 1 equipped with a lens 2. The invention will thus be described here through a device for cleaning the lens 2 of this optical sensor.
    Such a cleaning device comprises a fluid distribution assembly 3, here movable between a rest position and a working position, in a direction schematically represented by the double arrow F visible in FIG. 1. This fluid distribution assembly 3 comprises, in particular, a set of dispensing nozzles 4 by which one or more cleaning and / or drying fluids can be projected. In the working position of the cleaning device according to the invention, more particularly illustrated in FIG. 1, the distribution nozzles 4 are placed in such a way that they project this or these fluids onto the outer surface of the lens 2, allowing and to remove from it any traces and / or dirt that could disturb the detection by the optical sensor 1, and for example the shooting by a camera. The cleaning fluid is projected when the fluid distribution assembly 3 is in its working position, and the projection of the cleaning fluid can be followed by a projection of a drying fluid, in order to eliminate any trace or residue that the cleaning fluid could leave. In the rest position, not shown here, of such a cleaning device, the fluid distribution assembly 3 is set back from the surface of the lens 2, and no fluid is projected by the distribution nozzles 4. Thus, in the case illustrated, it can be considered that the cleaning operation of the lens 2 consists of the succession of a first step of displacement of the fluid distribution assembly 3, between the rest position and the working position. then a second cleaning fluid projection step.
    The optical sensor 1 is equipped with detection means 5 capable of generating a signal representative of the presence, on the surface of the lens 2, of possible foreign bodies such as dust, debris or other types of soiling. These detection means are configured to communicate with a control module 6, in particular so as to be able to transmit to this control module a first datum D1 representative of the presence of possible foreign bodies on the surface of the lens 2.
    The control module 6 is configured to first receive a first data D1 from the detection means associated with the optical sensor to be cleaned, as just mentioned, and secondly to emit a first signal S1 in direction of signaling means 7 capable of delivering, in the cabin of the vehicle, an information message M1 to the occupants of the vehicle which is representative of this first signal.
    Furthermore, the control module 6 is configured to receive a response to this first signal S1 in the form of a second data item D2 coming from recognition means 8 of a command instruction 11 of the driver, so as to control a cleaning operation of the optical sensor, that is to say in this case a displacement of the fluid distribution assembly between rest position and working position and a projection of cleaning liquid on the sensor lens.
    It is understood that the control module 6 can extend anywhere in the vehicle and that the signaling means 7 and the recognition means 8 are arranged inside the passenger compartment 9, schematically represented in broken lines. in Figure 1.
    The signaling means 7 are configured to deliver, in the cockpit 9, an information message M1 representative of the presence of possible foreign bodies on the surface of the lens 2.
    These signaling means 7 may comprise a screen, and in particular a screen used moreover by a management and control assembly of the vehicle of the on-board computer type, on which the information message M1 may consist of words signaling the need for clean the optical sensor. It is also possible to provide for the lighting of a warning light on the dashboard of the vehicle or, again, the delivery of an audio message in the cockpit.
    The recognition means 8 may comprise a detection camera for the gestural recognition of a user's movement or they may take the form of voice recognition means of an oral instruction of the user. They may also consist of a button 10 that the driver is invited to maneuver when he wishes to act on the cleaning device of the optical sensor, especially after viewing the information message M1.
    According to features of the invention specific to the operation of the recognition means, and that parasitic instructions do not degrade the performance of the system, it is expected that the recognition means 8 to trigger a command, from the passenger compartment, the performing a cleaning operation of the optical detection system, are active only when the information message M1 representative of the presence of possible foreign bodies on the surface of the optical sensor takes a predefined value. This is particularly useful when the recognition means consist of voice and / or gesture recognition means, in order to prevent them from being constantly lit.
    And it will be possible to envisage a lapse of time after the delivery of the information message M1 in which the command instruction must be formulated by the driver or any other occupant of the vehicle so that it is taken into account by the recognition means. , and by the control module.
    The control module is able to generate a second control command I2 intended for the fluid distribution assembly 3 so that the associated actuator generates the displacement of the fluid distribution nozzles and the projection of liquid towards the optical sensor.
    In other words, and with particular reference to the flowchart of FIG. 2, the optical sensor cleaning method according to the invention starts when foreign bodies are detected by the detection means 5 on the surface of the lens. 2 (step E1), a datum D1 representative of this presence then being transmitted to the control module 6 which analyzes this first datum to generate an information message to be sent to the users in the passenger compartment (step E2). The control module communicates with the signaling means 7 housed in the passenger compartment for the transmission of this information message M1 representative of the data item D1 (step E3), the type of the information message being able to depend on the urgency character information to be communicated and / or preferences set by the user. For example, urgent messages, relating for example to the total fouling of the sensor, can be relayed both by a visual medium and an audio message, while upstream prevention messages, relating for example to a beginning of clogging of the optical sensor, can be delivered in the form of only written messages if the driver does not wish to receive voice messages in his cabin. In response to this information message M1, the driver or any other occupant of the vehicle may or may not decide to perform the cleaning of the optical sensor, in particular according to his appreciation of the driving situation and the potential embarrassment that this cleaning could provide in this situation, and it can, within a suitable time, carry out a command instruction (step E4) recognizable by the recognition means 8 to start, via a control of the control module 6, a cleaning operation of the optical sensor ( step E5).
    According to various embodiments, once the cleaning operation of the lens or, more generally, of the optical sensor 2 controlled from the passenger compartment, this operation can be performed one or more times during a predefined period of time, or with a predetermined periodicity, several cleaning cycles can thus be configured. Thus, according to the embodiment chosen, the recognition means 8 participate in the development of a command, from the passenger compartment, of one or more displacements, successive or repeated at predefined time intervals, of the fluid distribution assembly 3 between the rest position and the working position. This limits the demands of the driver, allowing the driver to focus his attention on driving. In the same vein, namely to limit the demands of the driver, it can be expected to put an end to this repetition of cleaning cycles that the complete stop of the vehicle, so that the control instruction provided by the user is permanent until the vehicle stops.
    Furthermore, as illustrated in FIG. 1, provision can be made for the control module 6 of the device according to the invention to be configured to receive third data D3 from monitoring means 11 of one or more driving parameters. of the vehicle. By way of non-exhaustive examples, it may be a means of monitoring the speed of the vehicle (stopping the vehicle, very slow speed, medium or fast speed, stabilized or not, etc.), or means monitoring of the driving regime (vehicle in neutral, right or wrong trajectory, etc ...). These monitoring means 11 are able to generate one or more third data D3 representative of one or more predefined driving situations, and the control module 6 considers this third data to determine the possibility of a cleaning operation.
    It is advantageous for these monitoring means to be implemented during step E2, when, on the basis of the first data D1 received by the detection means 5, the control module 6 defines the next need for a cleaning operation. of the sensor.
    In this case, a parallel step is generated (step E3a, optionally represented in dashed lines in FIG. 2) during which said parameters are monitored in order to deduce a data item D3 that can be used by the control module and which will condition, according to this embodiment of the invention, the taking into account of the user command as it has been recognized (step E4) for the implementation of the cleaning operation (step E5).
    Here is illustrated a practical case where the taking into account of this third data D3 by the control module delays the implementation of the cleaning operation to preferential driving situations, while the user has expressed his wish to carry out this cleaning. It can be provided in a variant that this third data D3 is immediately taken into account by the control module and that the information message M1 is broadcast in the passenger compartment only under certain driving situations, and for example when stopped. of the vehicle, so that the user can safely answer this information message.
    The optical sensor cleaning device according to the invention can be applied with a cleaning assembly of one or more glazed surfaces 12 located at the front and / or rear of the vehicle. According to the invention, provision may be made for the control module 6 to be configured to control the operation of the cleaning assembly 12 in addition to the optical sensor cleaning device. In particular, it can be provided that the automatic release function of the glass cleaning assembly is coupled with an automatic trigger function cleaning a sensor. And it may be provided that the button, or lever, sensor cleaning instruction command is common to that associated with the triggering of the glass cleaning assembly, and in particular the triggering of the wiper blades.
    In such a configuration, the cleaning fluid supply of the sensor cleaning device 2 and the supply of cleaning fluid to the cleaning assembly of the front and / or rear glazing surface (s) 12 are advantageously performed. from a common storage tank 13 of cleaning fluid. In this context, the device according to the invention comprises monitoring means 14 for monitoring the level of fluid in the common storage tank 13. Advantageously, these monitoring means 14 are able to generate a fourth datum D4 representative of this level and transmitting this fourth datum to the control module 6, which is configured to selectively control, according to a predefined value of this fourth datum D4, the operation of the optical sensor cleaning device and the cleaning assembly of the one or more glazed surfaces.
    More specifically, and as illustrated in FIG. 3, the invention provides that if the level of cleaning fluid in the common storage tank 13 passes below a first predetermined threshold value Vs1, the fourth data item D4 transmitted to the control module 6 implies that only the cleaning of the optical sensor 2 can then be performed with the cleaning fluid still available in the common storage tank. Concomitantly, the invention provides that a message representative of this fourth data D4 is generated and displayed in the passenger compartment of the vehicle. Indeed, the cleaning operation of the sensor 2 of the optical detection assembly is then considered as a priority in terms of safety compared to the cleaning of the glass surfaces of the vehicle. Advantageously, the invention also provides that, when the liquid level in the common storage tank 13 passes below a second threshold value Vs2, lower than the first threshold value above, the monitoring means 14 generate and transmit to the control module a fourth data representative of this second value, so that a cleaning operation of the sensor 2 can not then be allowed for lack of cleaning fluid. Concomitantly, the invention provides that a corresponding message M2 is displayed in the passenger compartment.
    In the embodiments which have just been described, in which the cleaning device according to the invention comprises a cleaning assembly of one or more front and / or rear glazed surfaces of the vehicle, the invention comprises a step E6 of controlling the cleaning of this or these glazed surfaces, simultaneously with the control of the cleaning of the sensor 2 of the optical detection assembly. Advantageously, this method also comprises a step E7 for monitoring the level of the cleaning liquid in the common storage tank 13 and, as a function of the value taken by the fourth data D4 generated by the monitoring means 14 of this level, a control conditional step E6 surface cleaning (s) glass (s) or the only step E5 cleaning the optical sensor. The invention thus achieves its object by proposing a device and a method for cleaning a sensor 2 of an optical detection system in which the cleaning operation is subject to prior agreement by the driver or any occupant of the vehicle. , on the basis of information relating to the state of soiling of this sensor and / or to the driving situation of the vehicle transmitted to a control module 6 configured to drive both display means in the passenger compartment of the vehicle. vehicle and the means of cleaning the sensor according to the detection of the agreement of the occupant of the vehicle. The invention thus makes it possible to eliminate the driving situations in which such cleaning could be inconvenient with regard to a particular driving situation, or simply useless with regard to the state of soiling of this sensor. The invention can not, however, be limited to the means and configurations described and illustrated, but it also extends to any equivalent means or configurations and any combination of such means. In particular, it applies to any type of sensor of an optical detection assembly that can be installed on a vehicle.
