    Method and system for automatic adjustment of at least one piece of equipment of a motor vehicle
    Embodiments and embodiments of the invention relate to adjustment systems, and more particularly to automatic adjustment systems intended to equip motor vehicles and making it possible to carry out adaptive automatic adjustments to one or more pieces of equipment of the vehicle in the presence / absence of one or more people in the passenger compartment of a motor vehicle.
    In general, conventional motor vehicles provide a plurality of controllable settings for their interior and exterior equipment, such as the heights of the front seats, the activation / deactivation of airbags associated with the airbag. front passenger, or the interior and / or exterior mirror orientations, so that the drivers and passengers of these motor vehicles can adjust them manually so as to adapt them as best as possible to their particular needs.
    In addition, certain high-end motor vehicles are sometimes configured to provide several predefined settings and to be able to memorize certain settings implemented in particular by drivers.
    However, this still requires manual intervention by drivers and / or passengers to choose the predefined or memorized settings and this generally requires prior learning as to the implementation of these settings within these specific motor vehicles.
    There is thus a need to propose a low complexity technical solution allowing numerous adjustments to certain equipment of a motor vehicle so as to adapt to dynamic changes linked in particular to the presence or absence of one or more people. in the passenger compartment of the motor vehicle, and / or the physical characteristics of the people present.
    In one aspect, there is provided a method of automatically adjusting at least one piece of equipment in a motor vehicle. The method comprises detecting the presence of at least one person on at least one seat of the vehicle or the absence of a person on the front passenger seat of the vehicle, and at least one automatic adjustment of said at least one piece of equipment. depending on the detection result.
    Such a method advantageously makes it possible to dynamically adapt to the physical characteristics of the person or persons present in the vehicle, taking account of the seat or seats occupied, by implementing automatic adjustments adapted to the configuration of current occupancy of the vehicle.
    Thus, manual interventions by people in the vehicle are limited or even eliminated and even first-time users can obtain satisfactory adjustments which are adapted to them, without any prior training.
    According to one embodiment, if the presence of at least one person on at least one seat of the vehicle is detected, said at least one adjustment comprises an automatic adjustment of an audio configuration of a vehicle audio system in function of the seat or seats occupied by the person or persons detected.
    According to one embodiment, the automatic adjustment of the audio configuration comprises an adjustment of a reference listening position of a vehicle audio system, so as to place said reference listening position in the center of an area encompassing the seat or seats occupied by the person or persons detected.
    Thus, advantageously, all the people present in the vehicle can receive the best possible sound according to their positions, here their seats occupied in the vehicle.
    According to another embodiment, if the presence of at least one person on at least one seat of the vehicle is detected, the method comprises a determination of areas of the face and eyes of the person (s) on the seat or seats corresponding occupied, and said at least one adjustment comprises an automatic height adjustment of the corresponding occupied seat or seats and / or of the corresponding seat belts.
    According to this other embodiment, said automatic height adjustment comprises for example a first adjustment of the height of each corresponding occupied seat, then a second adjustment of the height of each corresponding seat belt.
    The first adjustment may for example comprise a first adjustment of the height of each corresponding occupied seat so as to make the height of the center of the eye area of the corresponding person substantially equal to a reference height.
    By "substantially equal" is meant for example "equal to a tolerance, for example less than 2 cm".
    The second adjustment can for example comprise a second adjustment of the height of each corresponding seat belt so as to make the height (HCSC, HC-SPA) of the corresponding seat belt substantially equal to the height of the lower limit of the zone. face of the corresponding person.
    According to yet another mode of implementation, if the absence of a person in the front passenger seat is detected, said at least one automatic adjustment comprises deactivation of the airbag or airbags associated with the front passenger seat.
    Such a method advantageously makes it possible to automatically deactivate the airbags (“Air bag” in English) if there is no person in the front passage seat, which is very practical or even mandatory in the event of installation of 'a rear-facing car seat in the front passenger seat under new European regulations dating from 2006.
    According to yet another embodiment, if the presence of a person on the driver's seat is detected, the method further comprises determining the areas of the face and eyes of the person on the driver's seat so as to determine the current position of the eyes of this person, and said at least one adjustment comprises a third adjustment of the vehicle mirrors as a function of the current position of the eyes.
    As a variant, the method further comprises a facial recognition of the person on the driver's seat, and in the event of recognition being successful, said at least one adjustment comprises the third adjustment with orientations of the vehicle mirrors memorized and associated with said person , and in the event of recognition failure, said at least one adjustment comprises a memorization of current orientations of the vehicle mirrors following the third adjustment.
    Such a method advantageously makes it possible to automatically apply suitable adjustments associated with a memorized driver once this driver is again detected in the driver's seat, which advantageously avoids manual intervention by the driver.
    The third adjustment may for example include a third adjustment of the orientations of the vehicle mirrors as a function of the angular difference between said current position and a reference position.
    As a result, any driver can obtain a suitable driving position and visibility using such a method. Furthermore, this process can follow in real time the variation in the position of the driver's face and then adjust the orientations of the mirrors, for example interior and exterior, to ensure adequate visibility of the mirrors at all times.
    According to yet another embodiment, the method further comprises a facial recognition of at least one person detected on at least one seat of the vehicle, and in the event of recognition being successful, the first adjustment is made with the or the seat heights stored and associated with said at least one person, the second adjustment is made with the seat belt height (s) stored and associated with said at least one person, and in the event of recognition failure, said at at least one adjustment comprises a memorization following the first adjustment, of the current seat height (s) of each occupied seat of the vehicle and a memorization following the second adjustment, of the current seat height (s) of at least one corresponding seat belt.
    According to another aspect, there is proposed a system for automatic adjustment of at least one piece of equipment of a motor vehicle. This system comprises detection means configured to detect the presence of at least one person on at least one seat of the vehicle or the absence of a person on the front passenger seat of the vehicle, and adjustment means configured to perform at minus an automatic adjustment of said at least one item of equipment as a function of the result of the detection.
    According to one embodiment, the adjustment means comprise a configured audio adjustment stage, if the detection means detect the presence of at least one person on at least one seat of the vehicle, for automatically adjusting an audio configuration of a system vehicle audio according to the seat or seats occupied by the person or persons detected.
    According to one embodiment, the audio adjustment stage is configured to automatically adjust the configuration of the vehicle audio system, by adjusting a reference listening position of the vehicle audio system, so as to place said position d reference listening in the center of an area including the seat or seats occupied by the person or persons detected.
    According to another embodiment, if the detection means detect the presence of at least one person on one of the front seats, the detection means are further configured to determine areas of the face and eyes of said at least one person on the corresponding front seat or seats, and the adjustment means also comprise a seat and seat belt adjustment stage configured to automatically adjust the height or heights of the corresponding front seat or seats and of the corresponding front seat belt or seats.
    According to said other embodiment, the seat and belt adjustment stage is configured to automatically adjust the height or heights of the corresponding front seat or seats and of the corresponding front seat belt or seat belts, by a first adjustment of the height. of each corresponding front seat, then by a second adjustment of the height of each corresponding front seat belt.
    By way of nonlimiting example, the stage for adjusting seats and belts can also be configured to carry out the first adjustment by a first adjustment of the height of each corresponding front seat so as to make the height of the center substantially equal. of the eye area of the corresponding person and a reference height, and carry out the second adjustment by a second adjustment of the height of each corresponding front seat belt so as to make the height of the corresponding front seat belt substantially equal and the height of the lower limit of the face area of the corresponding person.
    According to yet another embodiment, the adjustment means further comprise an airbag adjustment stage configured, if the detection means detect the absence of a person in the front passenger seat, to deactivate one or more airbags associated with the front passenger seat.

    As a variant, the visibility adjustment stage may include a memory configured to store conductive profiles, the detection means may also be configured to perform facial recognition of the person detected on the driver's seat using the memory.
    If the recognition is successful, the visibility adjustment stage can be configured to make the third adjustment with orientations of the vehicle mirrors stored in the memory and associated with said person.
    In the event of recognition failure, the memory can be configured to memorize the current orientations of the vehicle's mirrors following the third adjustment.
    The visibility adjustment stage can for example be configured to perform the third adjustment by a third adjustment of the orientations of the vehicle mirrors as a function of the angular difference between said current position of the eyes and a reference position.
    According to another embodiment, the detection means are further configured to perform facial recognition of at least one person detected on at least one seat of the vehicle using the memory.
    In the event of successful recognition, the seat and belt adjustment stage is configured to carry out the first adjustment with the height or heights of at least one vehicle seat stored in the memory and associated with said at least one person. and the second adjustment with the height or heights of at least one seat belt stored in the memory and associated with said at least one person.

    According to one embodiment, the detection means can comprise, for each seat of the vehicle, a dedicated vision camera and arranged opposite the corresponding seat.
    Advantageously, said at least one vision camera can be of the time-of-flight type.
    According to another embodiment, the detection means also comprise, for each seat of the vehicle, a seat belt locking sensor and / or an occupancy sensor.
    According to yet another aspect, a motor vehicle is proposed comprising at least one system as defined above.
    Other advantages and characteristics of the invention will appear on examining the detailed description of modes of implementation and embodiments, in no way limiting, and the appended drawings in which:
    - Figures 1 to 12 schematically illustrate modes of implementation and embodiment of the invention.
    FIG. 1 illustrates an example of a motor vehicle 1, here for example a car 1 comprising, in its passenger compartment 2, front seats, rear seats, an interior mirror RI, a left exterior mirror REG and a right exterior mirror RED and an automatic adjustment system 3 of at least one item of equipment of the car 1 according to one embodiment.
    The front seats of the car 1 can for example comprise a driver seat SC of which at least the height is electronically controllable, and a front passenger seat SPA.
    The rear seats of the car 1 can for example comprise a left rear seat SAG, a central rear seat SAC and a right rear seat SAD.
    It should be noted that it is possible to have several rows of rear seats for cars with six or more seats. For the sake of simplification, only examples are shown with cars having five seats.
    Reference is now made to FIG. 2 to schematically illustrate an example of the automatic adjustment system 3 according to one embodiment.
    The automatic adjustment system 3 comprises detection means 4 configured to carry out a detection of the presence or absence of a person on each seat SC, SPA, SAG, SAC, SAD of the car 1 (FIG. 1), and adjustment means 5 configured to perform, as a function of the result of the detection, at least one corresponding automatic adjustment of said at least one item of equipment in car 1.
    To do this, the detection means 4 comprise for example at least one vision camera CV, here for example a vision camera CV of the time of flight type (“Time of Flight”: ToF in English) known to man of the trade and operating on the principle of time of flight and allowing to measure in real time a three-dimensional scene.
    In order to have the largest possible detection space, the CV vision camera can have a wide angle lens. As illustrated in a dotted square in FIG. 1, the CV camera can advantageously be placed in front of the passenger compartment 2 of car 1, here for example by bonding to the windshield of car 1, and oriented towards the rear of the passenger compartment 2 so as to make it possible to detect the faces of all the people potentially present in the car 1.
    Alternatively, to further improve the quality of detection of the presence or absence of a person on each seat Sn (n = C, PA, AG, AC, or AD) of car 1, the detection means 4 (FIG. 2) may comprise, for each seat Sn of the car 1, a dedicated CV-Sn vision camera arranged for example at the top opposite each seat Sn, as illustrated in FIG. 1.
    In this case, if the face and eyes of a person occupying this seat Sn are detected by a vision camera CV-Sn dedicated to the seat Sn occupied and having a detection space focusing particularly on this seat Sn, we consider while the person is actually detected.
    In this regard, one can for example use algorithms cited in the free graphic library called "OpenCV" and known to those skilled in the art to detect the face and eyes of a person by a vision camera, for example both following:
    "Eye tracking method" (https://goo.gl/Fw6S04) "Face detection method using Haar waterfalls" (https://goo.gl/XJNRDk)
    Although this is not essential, the detection means 4 may further comprise (FIG. 1) for each seat Sn of the car 1, a seat belt fastening sensor CB-Sn known per se and intended to monitor the state of closure of the corresponding CS-Sn belt, and a CO-Sn seat occupancy sensor, here for example one or more pressure detectors known per se and arranged in the corresponding Sn seat.
    Therefore, according to the embodiment illustrated in Figure 1, the detection means 4 are configured to determine the presence or absence of a person on a seat of the car 1 by combining the results of the detections of the cameras of dedicated CV-Sn vision, CB-Sn loop sensors and CO-Sn seat presence sensors.
    The presence of a person on any seat Sn of the car 1 can therefore be determined, if for example the detection results of the corresponding vision camera CV-Sn, of the corresponding looping sensor CB-Sn, and of the sensor d 'CO-Sn corresponding seat occupancy are jointly positive.
    For example, in a case where the result of the detection of the CV-SPA vision camera dedicated to the front passenger seat SPA is negative while the results of detection of the corresponding CB-SPA, COSPA sensors are positive, the means 4 are configured to detect the absence of a person in the front passenger seat SPA.
    This case indeed presents a concrete case when a car seat called "rearward facing" is installed on the front passenger seat SPA of car 1.
    The description of the adjustment of the airbags associated with the front passenger seat SPA will be detailed below with reference to FIG. 8.
    FIG. 3 illustrates an IMG image taken by a CV-Sn vision camera of the car 1. As indicated above with the two algorithms mentioned, each CV-Sn vision camera of the detection means 4 is configured to dynamically and precisely determine a face area ZV and areas of the eyes ZY of a person P (FIG. 3) on the corresponding seat Sn of car 1.
    It should be noted that all vision cameras CV-SC, CV-SPA, CV-SAG, CV-SAC, CV-SAD are oriented towards the rear of the passenger compartment 2 and their positions relative to the passenger compartment 2 is also known.
    Thus, the pixels of the IMG image taken by a CV-Sn vision camera represent an EL element detected, here for example the person's left eye, in the passenger compartment 2 by this CV-Sn camera. The coordinates of the EL element in the passenger compartment 2 on the X and Y axes of the IMG image can be calculated.
    Once the face area ZV and the eye areas ZY of the person P are determined, each vision camera CV-Sn is configured to detect the center of gravity of the eyes CGY of the person P.
    The CGY eye center of gravity is located in the middle of the ZY eye areas and its X and Y axis coordinates can be calculated from those of the ZY eye areas.
    Reference is now made to FIG. 4 to schematically illustrate an example of a determination of the Z axis coordinate of an element, here for example the center of gravity of the driver's eyes CGY, for example by the vision camera CV- SC dedicated to the SC driver's seat.
    As an indication, the Z axis is defined parallel to the longitudinal direction of the car 1 and the position of the CV-SC camera forms an angle β relative to the Z axis.
    In addition, the CV-SC camera is configured to detect the distance D between the position of the CV-SC camera and the center of gravity of the CGY eyes.
    In fact, like all other vision cameras, CV-Sn (nAC), the CV-SC vision camera illuminates its detection space, here the passenger compartment 1, and an object to be measured, here the driver C in the car 1, by a light radiation, and calculates the time that this flash takes to make the round trip between the conductor C and the camera CV-SC. The time of flight of this radiation is directly proportional to the distance D between the CV-SC camera and the conductor C.
    The CV-SC camera is thus configured to calculate the coordinate Dz along the Z axis of the center of gravity of the eyes CGY from the distance D and the angle β.
    As a non-limiting indication, this calculation of the Dz coordinate can also be carried out using a distance sensor in addition to a non-ToF camera.
    FIG. 5 also illustrates the distances to be measured on the face V of the driver C by the vision camera CV-SC for automatic adjustments of the mirrors RI, REG, and RED which will be detailed below in the description. Note that Figure 5 illustrates an IMG-SC image taken by the CV-SC vision camera.
    More precisely, the CV-SC camera is configured to measure a first distance DI between the center of gravity of the eyes CGY of the conductor C and the lower limit of the image IMG-SC, a second distance D2 between the center of gravity of the eyes CGY and a lateral limit of the IMG-SC image, and a third distance D3 representing the length of the face of the conductor C.
    Returning now to FIG. 2, the adjustment means 5 here comprise for example an audio adjustment stage 6, a seat and seat belt adjustment stage 7, an airbag adjustment stage 8 and an adjustment stage visibility 9.
    The adjustment means 5 can, for example, be implemented in software form or using specific circuits, for example within a microcontroller.
    Reference is now made to FIGS. 6a to 6f to illustrate an example of the operations of the audio adjustment stage 6.
    The car 1 comprises an audio system 10 comprising, here for example four speakers respectively disposed near each side door of the car 1.
    The audio adjustment stage 6 is coupled to the audio system 10 and configured to control the audio system 10 so as to adjust a reference listening position PER (“Acoustic Sweet Spot” in English) known to those skilled in the art and adapted to the presence of the person (s) in the car 1.
    It should be noted that this audio adjustment is advantageously carried out in real time by the audio adjustment stage 6, taking into account any change in the presence / absence of people in the car 1.
    In a case illustrated in FIG. 6a, if only one person, here the driver, is present in the car 1, this presence is detected by the detection means 4, and the audio adjustment stage 6 is configured to place the position reference sheet PER in the center of a zone Z encompassing the driver's seat SC.
    If the presence of two people is detected by the detection means 4 (FIGS. 6b to 6d), the audio adjustment stage 6 is configured to control the audio system 10 so as to place the reference listening position PER in the center a zone Z encompassing the seats occupied by these detected persons.
    By analogy, if there are three (Figure 6e) or even five people (Figure 6f) detected in the passenger compartment 2 by the detection means 4, the reference listening position PER of the audio system 10 will be adjusted in the center d 'A zone Z encompassing these seats occupied by these three or even five people present in the passenger compartment, as illustrated in Figures 6e and 6f.
    FIG. 7 illustrates an example of adjustments made by the seat and belt adjustment stage 7 for the driver SC and front passenger SPA seats of car 1.
    The settings illustrated in Figure 7 can also apply to the rear seats if at least one person is detected in at least one of these rear seats.
    It should be noted that the heights of the driver's seat SC and the front passenger SPA and the corresponding seat belts CS-SC or CSSPA are electronically controllable by the seat and seat adjuster stage 7.
    FIG. 7 illustrates an image taken IMG-SPA by a CV-SPA vision camera dedicated to one of the front seats, here for example the front passenger seat SPA.
    Once the face area ZV, the eye areas ZY and the center of gravity of the eyes CGY are detected, the seat and belt adjustment stage 7 is configured to compare the height HCGY of the center of gravity of the eyes, that is to say the X axis coordinate of the center of gravity of the eyes CGY, with a reference height HR, for example predefined by the manufacturer of the car 1 so as to ensure better visibility towards the front of the car 1.
    If the height HCGY of the center of gravity of the eyes and the reference height HR are different, the adjustment stage 7 is configured to adjust the height of the corresponding seat H-SPA so as to make it substantially equal to the reference height HR . The positions of the ZV face area and the ZY eye areas are accordingly changed.
    It should be noted that the manufacturer of the car 1 can for example predetermine at least one tolerance during the calibration of the car in order to take into account a possible offset between the seats Sn of the car 1 and the corresponding belts.
    Then, the seat and belt adjustment stage 7 is configured to adjust the height of the seat belt of the front passenger seat CS-SPA so as to make the height of the corresponding seat belt HC-SPA and the height HLIZV of the seat substantially equal. lower limit of the ZV face area obtained after adjusting the height of the corresponding SPA seat.
    As a result, the driver or front passenger can obtain the heights of the corresponding seat SC or SPA and of the corresponding belt CS-C or CS-SPA which are adapted to it and better visibility towards the front of the car 1.
    It should be noted that the driver or front passenger can always carry out manual adjustments later and this automatic adjustment of seats and belts can also be deactivated at any time.
    Reference is now made to FIG. 8 to illustrate an example of a method for automatically adjusting airbags carried out by the airbag adjusting stage 8. It should be noted that the CG-SPA airbags from Safety associated with the front passenger SPA seat are all activated by default.
    Following the start of the system 3, the detection means 4 detect in a first step 8-ETP1 whether the seat belt CS-SPA of the front passenger seat is fastened.
    If so, the detection means 4 are then configured to activate the corresponding vision camera CV-SPA so as to detect the presence or absence of a person on the front passenger seat SPA (8-ETP2).
    In the third step 8-ETP3, if the presence of a person is detected, that is to say the face area ZV and the areas of the eyes of this person are detected by the CV-SPA camera, the process proceeds. completes and the airbags for the CG-SPA front passenger seat remain activated.
    Otherwise, the airbag setting stage 8 is configured to deactivate all the airbags associated with the CG-SPA front passenger seat (8-ETP4).
    It is important to note that the driver will preferably always be informed of this deactivation, for example by a message on a display means of the car 1, and he can always cancel this automatic deactivation if he wishes.
    Otherwise, after a period of time, the CG-SPA cushions could be automatically deactivated by the airbag setting stage 8. In a safety aspect, it is preferable to require a response from the driver in order to be sure that the driver is well aware of this deactivation.
    FIGS. 9 and 10 schematically illustrate an example of an automatic mirror adjustment method performed by the visibility adjustment stage 9.
    FIG. 9 shows a reference position PR of the driver, more precisely a reference position PR of the center of gravity of the driver's eyes CGY, defined for example by the manufacturer of the car 1.
    The mirrors RI, REG and RED of car 1 are consequently adjusted in reference orientations so as to provide better interior and exterior visibility towards the rear of car 1. Figure 9 illustrates in this regard three lines of vision of reference LVR for these three mirrors RI, REG and RED.
    It should be noted that the interior mirrors RI and exterior mirrors REG and RED of car 1 are advantageously controllable in orientation, in other words in altitude as well as in azimuth.
    As a general rule, the various adjustments of the mirrors in relation to the reference position PR are carried out in a similar manner. For the sake of simplification, only an adjustment of an azimuth mirror is presented with reference to FIG. 10. It is also assumed that the current position PC of the center of gravity of the eyes CGY and that of the reference PR are at the same height (X axis).
    The reference M in FIG. 10 represents a mirror M of any rear-view mirror. The origin O of the Z and Y coordinate system represents the azimuth axis of rotation of the mirror M.
    An angle a is formed between the reference position PR and the reference line of sight LVR and an angle Δ is formed between the current position PC and the reference position PR.
    Once the coordinates in Y and Z axes of the positions PR and PC are known, the visibility adjustment stage 9 is configured to calculate the angle Δ by applying for example the well-known theorem of AL-Kashi.
    As the angle a is predefined by the manufacturer of the car 1, the angle formed between the current position and the LVR reference line of sight can be calculated by combining the angles a and Δ.
    The visibility adjustment stage 9 is configured to adjust a new orientation of the mirror M, being perpendicular to the bisecting line of the angle α + Δ.
    As a variant, the visibility adjustment stage 9 also comprises a memory MEM (FIG. 1) configured to store new positions of the mirrors RI, REG, RED of the car 1 for a registered driver profile.
    We now refer to Figure 11 to illustrate an example of a visibility adjustment process before starting the car
    1.
    The method begins with a first step 11-ETP1 comprising a detection of the face area ZV, of the eye areas ZY and of the current position PCCGY of the center of gravity of the driver's eyes and then a second step 11-ETP2 comprising of a recognition facial RF on the detected face area ZV of the conductor using a comparison with PE profiles of conductors recorded in the memory MEM.
    If recognition is successful, the visibility adjustment stage 9 is configured to adjust the orientations of the mirrors RI, REG, RED of car 1 according to the data recorded in the registered profile PE of this driver (11-ETP3) .
    In the event of recognition failure, the visibility adjustment stage 9 is configured to request authorization from the driver in order to adjust the mirrors RI, REG, RED (11ETP4). The driver can, for example, authorize it by simply placing their hands behind the wheel or by voice confirmation via a voice recognition system.
    After the detection of the new orientations of the RI, REG, RED mirrors adapted to the driver, the visibility adjustment stage 9 is also configured (11-ETP5) to request confirmation from the driver so as to validate these new orientations. . In the event of dissatisfaction, the driver can always manually make conventional adjustments to the RI, REG, RED mirrors of car 1.
    If the driver agrees, the memory MEM is configured to create, in the next step 11-ETP6, a new profile NP for this driver and store these new orientations set by the visibility adjustment stage 9 or the settings manuals made by the current driver in the registered profile of the current driver.
    Figure 12 illustrates an example of an automatic adjustment method for RI, REG, RED mirrors when car 1 is in motion.
    In the first step 12-ETP1 of this method, the detection means 4 are configured to detect the coordinate Dz along the axis Z of the center of gravity of the eyes CGY of the driver of the car 1, and the first, second and third distances DI to D3, illustrated in Figures 4 and 5.
    The detection means 4 are then configured to detect (12-ETP2) if there is a change in the settings of the driver's seat SC.
    In the event of no modification, the detection means 4 are further configured to detect (12-ETP3) if the mean values of the coordinate Dz, and of the first, second and third distances DI to D3 are modified and remain stable for at least N seconds, here for example 30 seconds.
    If the results of the 12-ETP2 and 12-ETP3 detections are all negative, the process ends.
    Otherwise, that is to say if the result of at least one of the two detections 12-ETP2 and 12-ETP3 is positive, the visibility adjustment stage 9 is configured to determine new orientations NP of the mirrors RI, REG, RED adapted to the current position PCCGY of the center of gravity of the driver's eyes in the passenger compartment 2 so as to dynamically obtain better visibility towards the rear of the car 1.
    By analogy, facial recognition can for example also be carried out via each CV-Sn camera dedicated to each seat Sn using the memory MEM, when at least one person P is detected on at least one seat Sn of the car 1 and the heights of all seats and all belts are adjustable.
    If the recognition is successful, the seat and seat belt adjustment stage 7 is configured to adjust the seat height with the height or heights of at least one seat Sn of the car 1 stored in the memory MEM and associated with said at least one person P, and the adjustment of the seat belt height with the height or heights of at least one seat belt HC-Sn stored in the memory MEM and associated with said at least one person P.
    In the event of recognition failure, the memory MEM is configured to memorize, after adjusting the seat height, the current seat height (s) (H-Sn) of each occupied seat (Sn) of the vehicle (1 ), and to memorize following the adjustment of the seat belt height, the current belt height (s) (HC-Sn) of each corresponding seat belt (CS-Sn).
