Description

Title of the invention: Method and device for adjusting comfort and / or safety functions of a vehicle

[0001] The field of the invention is that of the human-machine interface of a vehicle and more particularly the adjustment of comfort and / or safety functions.

[0002] It is known to equip a motor vehicle with one or more digital rearview mirrors comprising a screen displaying images of the external environment captured by cameras. These devices are beginning to replace traditional rearview mirrors with reflective mirrors arranged on either side of the front, left and right doors.

[0003] Document EP 2 822 814 describes a vehicle comprising a digital rearview mirror, in particular an exterior and / or side rearview mirror, which comprises at least one touch screen displaying images captured by a camera arranged outside the vehicle. A representation parameter of the display device, in particular the brightness and / or the contrast and / or a color parameter, is adjustable on the touch screen.

[0004] These new dedicated function settings for digital rearview mirrors are added to the other existing vehicle function settings. This also results in an additional interface for interaction with users. This multiplicity of interfaces contributes to the increase in vehicle manufacturing costs by the addition of numerous components (buttons, wiring, etc.). This multiplicity also contributes to complexity of use for users.

[0005] An object of the present invention is to propose a solution for simplifying access to the vehicle function settings while reducing the manufacturing cost of the vehicle.

[0006] More specifically, it proposes for this purpose a method for adjusting vehicle functions, said vehicle comprising a driver's side and a passenger's side, said vehicle comprising a digital rearview mirror system.

[0007] The digital rearview mirror system comprises at least one camera 102, 103 capturing images of the exterior of the vehicle, a first touch screen 104, arranged on the driver's side, dedicated to displaying the exterior environment on the driver's side, a second touch screen 105, arranged on the passenger's side, dedicated to displaying the exterior environment on the passenger's side, a computer 106 processing images captured by said camera 102, 103 and displaying them on said screens 104, 105.

[0008] The method is implemented by said computer 106, said method comprising a step 202 of displaying, on one of the touch screens 104, 105, a function setting of the digital rearview mirror system in response to the detection 201 of a first command. The method is characterized in that it further comprises a step 204 of displaying the setting of comfort and / or safety functions of the vehicle in response to the detection 203 of a second command.

[0009] Thus, the digital rearview mirror system is enhanced with additional settings, in particular settings for comfort and / or safety functions. This makes it possible, for example, to at least partially eliminate adjustment buttons; which has the effect of reducing the cost of these comfort and / or safety functions. The invention also allows, in particular, the passenger to access function settings more easily.

[0010] Advantageously, the method further comprises a step of determining a life phase of the vehicle from vehicle data, the display of adjustment of comfort and / or safety functions of the vehicle depending on the determined life phase.

[0011] Thus, in certain vehicle life situations, access to settings for certain comfort and / or safety functions is not possible, allowing priority to be given to the display of the external environment.

[0012] Advantageously, the vehicle data includes the vehicle speed, if the determined life phase is associated with a vehicle speed greater than a threshold then the display of the settings of the comfort and / or safety functions is inhibited at least in part.

[0013] Thus, during the driving phase, for example, the setting corresponding to the opening of the trunk or a door is not displayed, which improves safety.

[0014] Advantageously, the method is characterized in that the display on the second touch screen 105 for adjusting comfort and / or safety functions of the vehicle is different from the display on the first touch screen 104.

[0015] Thus, for example, on the passenger side, only the comfort and / or safety functions relating to the passenger side are offered. This has the effect of improving ergonomics. This makes it possible to display only the useful or necessary settings on each screen.

[0016] Advantageously, the method further comprises a step 205 of detecting a third command selecting an order for adjusting comfort and / or safety functions, and a step 206 of transferring the selected adjustment to equipment implementing the comfort and / or safety function.

[0017] Thus, the driver and / or passenger can interact and adjust actions of comfort and / or safety functions of the vehicle from a touch screen of the digital rearview mirror system to the driver and / or passenger.

[0018] Advantageously, the method further comprises authentication of the driver and / or the passenger.

[0019] Thus, access to settings of comfort and / or safety functions is only authorized for certain people. For example, deactivation of the passenger airbag is only done by an authenticated adult.

[0020] Advantageously, the method is characterized in that the display for adjusting comfort and / or safety functions of the vehicle is superimposed on the display of the external environment.

[0021] Thus, the driver can continue to see what is happening outside the vehicle.

[0022] The invention also relates to a digital rearview mirror device comprising at least one camera 102, 103 capturing images of the exterior of the vehicle, a first touch screen 104, arranged on the driver's side, dedicated to displaying the exterior environment on the driver's side, a second touch screen 105, arranged on the passenger's side, dedicated to displaying the exterior environment on the passenger's side, a computer 106 processing images captured by said camera 102, 103 and displaying them on said screens, and implementing the method for adjusting vehicle functions according to the invention.

[0023] The invention also relates to a vehicle characterized in that it comprises a device according to the invention.

[0024] The invention also relates to a computer program comprising instructions adapted for executing the steps of the function adjustment method according to the invention when said program is executed by at least one processor.

[0031] [Fig.l] shows a vehicle 101 having a digital rearview mirror system. The vehicle has a driver's side and a passenger's side. The digital rearview mirror system comprises at least one camera 102, 103 capturing images of the exterior of the vehicle, a first touchscreen 104 arranged on the driver's side, a second touchscreen 105 arranged on the passenger's side, and a computer 106. A communication channel 107, for example a CAN network, connects these components.

[0032] In the embodiment of [Fig.l], the vehicle comprises a first camera, 102, on the driver's side, and a second camera, 103, on the passenger's side.

[0033] In another embodiment not illustrated, the vehicle comprises a single camera advantageously placed on the roof making it possible to capture images of the vehicle's external environment.

[0034] [Fig.3] shows a view of the driver's side touch screen in the absence of a control.

[0035] The computer 106 can also be connected to a second computer 108 using a second communication channel 109. The second computer 108, using a third communication channel 110, can be connected to devices controlling comfort and / or safety functions.

[0036] The adjustment of comfort and / or safety functions allows a user, for example, to open or close

[0037] - an opening (a door or a window 111, 112, 113, 114, a trunk 115, a hood...) - storage (glove box, in the armrest, the doors, etc., on the central console, etc.).

[0038] This also makes it possible to choose whether or not to lock the state of an opening (for example, to prevent a child from opening the door, window, etc.), a storage area, or a function such as starting, the airbag, access to personal data, the car wash tunnel mode, child safety, air conditioning, etc. In addition, this also makes it possible to adjust a function such as the ventilation and temperature of the air conditioning, or the sound environment.

[0039] The computer 106 implements the method of the present invention, a logic diagram of which is shown in [Fig. 2]. Advantageously, this method comprises a first step 201 detecting a first command, resulting from pressing one of the touch screens 104, 105.

[0040] In response to this detection, step 202 displays on one of the touch screens 104, 105 the settings relating to the digital rearview mirror system.

[0041] Following detection of a second command, step 203, step 204 allows the settings relating to the comfort and / or safety functions to be displayed. The detection of the second command can be carried out by pressing the screen. touch by a user.

[0042] According to a first embodiment, this support can be made by a single finger on the screen or on a particular region such as for example on an icon 401 as, for example, illustrated in [Fig.4]. This support can also be multiple. This support can be a diagram or drawing.

[0043] According to a second illustrated embodiment [Fig.5], access to the settings is done using icons 501, 502, 503, 504, 505, 506. Access can also be done using a display of text, menus and sub-menus, a scroll bar, a check box or other.

[0044] Preferably, the exterior view filmed by the camera 102, 103 will not be entirely replaced. The information is displayed in a filagram, in transparency or on the periphery of the screen so as not to interfere with rear vision.

[0045] The detection of a third command, step 205, makes it possible to identify a setting of a comfort and / or safety function. This setting is then transferred by the computer 106 via a communication channel to a second computer 108, thus making it possible to carry out the setting on the comfort and / or safety function.

[0046] Advantageously, the method according to the invention further comprises a step of determining a life phase of the vehicle from vehicle data. The computer 106 can either retrieve data from the vehicle passing over the communication channel 109, or request data by a particular CAN request from the computer 108. The engine speed, the data representative of the dynamics of the vehicle such as the speed of the vehicle, the direction of travel, the selected driving mode, the active AD AS functions, the steering wheel angle, the position of the ignition key (+APC), the presence of a driver or a passenger, the location, the information related to the state of charge and / or health of a battery, the information available in the supervisors such as the battery supervisor BMS) ..., can be data retrieved by the computer 106.

[0047] The computer 106 can then determine a life phase of the vehicle, such as, for example: the vehicle is moving or stopped; the engine is running or stopped; the battery charging phases, the indicator is activated or not; the driver performs a maneuver such as turning the steering wheel; the vehicle is in autonomous mode or not; the vehicle is occupied or not; the openings (doors, windows, trunk, etc.) are open or closed; the vehicle is in diagnostic mode; etc.

[0048] The display of the adjustment of comfort and / or safety functions of the vehicle depends on the determined life phase, in other words, depending on the determined life phase, following step 203, the computer 106 displays a subset of the settings. For example, if the vehicle is stationary and the engine is running, all of the settings can be displayed, such as opening the doors and / or the trunk. Conversely, if the vehicle is rolling, access to opening the doors and / or trunk is no longer displayed or is inhibited.

[0049] Advantageously, the display of the settings of the comfort and / or safety functions is different between the driver's side and the passenger's side. On the driver's side, all the functions can be presented. On the passenger's side, only functions not related to driving or the driver's position are displayed, such as, for example, opening the passenger window.

[0050] Following the display of the comfort and / or safety function settings, the user can make an adjustment to a function such as, for example, opening the window. The window opening command is then transmitted via the available communication channels 107, 109, 110 to the door computer to carry out the action.

[0051] Advantageously, the method according to the invention further comprises a step of authenticating the driver and / or the passenger. Indeed, access to the setting of certain functions may require an authentication step to, for example, identify the owner of the vehicle and / or an authorized occupant. The authentication step can be carried out on the touch screen 104 or 105 by a diagram to be drawn, by entering a code, by repetitive presses on the screen according to a predefined rhythmic sequence, by recognition of the fingerprint, etc. Following authentication, it is possible, for example, to open the glove box, the trunk or a storage compartment, to start the vehicle, etc.
