Description

Title of the invention: Method and device for controlling a vehicle's exterior rearview mirror tilting system. Technical field

[0001] The invention relates to methods and devices for controlling an exterior rearview mirror tilting system of a vehicle, particularly, but not exclusively, a motor vehicle. The invention specifically relates to a method and device for displaying a control button for activating an exterior rearview mirror tilting system of the vehicle. Technological background

[0002] Modern vehicles are equipped with exterior mirrors that allow the driver to see what is happening behind the vehicle. These vehicles have systems for adjusting the tilt of these exterior mirrors, so that the driver can adjust their angle for optimal visibility. These adjustment systems allow for manual or electric adjustment of the exterior mirrors' tilt.

[0003] During a reversing parking maneuver, such as parking alongside a curb, which requires precisely aligning the wheels with the curb, the driver may want to check the alignment of the wheels with the curb. Some systems in modern vehicles therefore offer a function that allows the exterior mirrors to tilt vertically downwards at a predetermined angle, enabling the driver to see the underside of the vehicle. The system memorizes the initial position of the mirrors, and the mirrors are automatically returned to their original position at the end of the parking maneuver.

[0004] In some cases, the vertical tilt function is activated manually by pressing a physical button on the mirror adjustment device, which is located in the vehicle door. This button is small, making it difficult to operate, as the driver must simultaneously remain vigilant of their surroundings during parking maneuvers.

[0005] In the latest vehicles, this function is activated automatically when a parking maneuver is detected. However, in certain situations, the driver may not want to activate this function and prefer to keep the standard mirror positioning. Deactivating such a function requires accessing the vehicle settings via a touchscreen HMI (Human-Machine Interface) and pressing an activation button. deactivation of the automatic tilting function of the mirrors during a parking maneuver.

[0006] This button is usually located in a submenu and requires navigating through several settings and making successive clicks on the touchscreen to activate it. This operation is incompatible with a parking maneuver that must be performed quickly, and it distracts the driver in a situation that requires vigilance and precision in the parking maneuver. Summary of the present invention

[0007] One object of the present invention is to solve at least one of the problems of the technological background described above.

[0008] An object of the present invention is, for example, to facilitate the control or command of a tilting system of at least one exterior rearview mirror of a vehicle.

[0009] Another object of the present invention is, for example, to minimize the loss of driver attention and to improve vehicle safety.

[0010] According to a first aspect, the present invention relates to a method for controlling a tilting system of at least one exterior rearview mirror of a vehicle, the vehicle having a display system including a touch screen, the method being implemented by a processor and comprising the following steps: - receipt of initial data indicative of the detection of a vehicle parking maneuver, - display control of a tilt control button for at least one exterior rearview mirror on a main display area of ​​the touchscreen according to a first graphical representation based on initial data, the size of the control button according to the first graphical representation being greater than a first determined threshold, - reception of second data points representing a first touch press on the control button, - transmission of third data representing a tilt command of at least one exterior mirror to a controller of the tilt system of at least one exterior mirror, the transmission being triggered by the reception of the second data.

[0011] Detecting a vehicle parking maneuver allows for significant responsiveness depending on driving conditions, increasing the speed of execution of the parking maneuver. Displaying a tilt system control button on the touchscreen with a large size, i.e., greater than a predetermined threshold, allows for quick and intuitive pressing compared to a button physical or tactile of reduced size, without the driver needing to take their attention away from the road to look for the button, allowing to improve the driver's attention during the parking maneuver, and thus improve the safety of the vehicle and other road users.

[0012] According to one variant, the first threshold represents a ratio between the size of the control button and a total size of a main display area of ​​the touch screen.

[0013] According to one variant, the first threshold is equal to 90%.

[0014] According to another variant, the first threshold is configurable via an HMI (Human-Machine Interface) Man-Machine) of the vehicle.

[0015] According to yet another variant, the parking maneuver is a maneuver of engaging the reverse gear of the vehicle.

[0016] According to yet another variant, the method further includes a step of receiving third data representing a second touch press on the control button, and a step of transmitting fourth data representing a command to return at least one exterior mirror to an initial position to the controller, the transmission being triggered by the reception of the third data.

[0017] According to another variant, the method includes a step of display control of the tilt system control button of at least one exterior rearview mirror on the touch screen according to a second graphic representation, a size of the control button according to the second graphic representation being less than a second threshold, the second threshold being less than the first threshold.

[0018] According to another variant, the display of the control button according to the second graphic representation is carried out on a secondary display area of ​​the touch screen.

[0019] According to a second aspect, the present invention relates to a control device for a tilting system of at least one exterior rearview mirror of a vehicle, the device comprising a memory associated with a processor configured for the implementation of the steps of the method according to the first aspect of the present invention.

[0020] According to a third aspect, the present invention relates to a vehicle, for example of the automobile type, comprising a device as described above according to the second aspect of the present invention.

[0021] According to a fourth aspect, the present invention relates to a computer program which includes instructions adapted for carrying out the steps of the process according to the first aspect of the present invention, in particular when the computer program is executed by at least one processor.

[0022] Such a computer program can use any programming language, and be in the form of source code, object code, or a intermediate code between source code and object code, such as in a partially compiled form, or in any other desirable form.

[0023] According to a fifth aspect, the present invention relates to a computer-readable recording medium on which is recorded a computer program comprising instructions for carrying out the steps of the process according to the first aspect of the present invention.

[0024] On the one hand, the recording medium can be any entity or device capable of storing the program. For example, the medium can include a storage means, such as a ROM, a CD-ROM or a microelectronic circuit-type ROM, or a magnetic recording means or a hard disk drive.

[0025] On the other hand, this recording medium can also be a transmissible medium such as an electrical or optical signal, such a signal being able to be transmitted via an electrical or optical cable, by conventional or radio frequency, by self-directing laser beam, or by other means. The computer program according to the present invention can, in particular, be downloaded from an Internet-type network.

[0026] Alternatively, the recording medium may be an integrated circuit in which the computer program is incorporated, the integrated circuit being adapted to execute or to be used in the execution of the process in question. Brief description of the figures

[0035] A method and a device for controlling a tilting system of at least one exterior rearview mirror of a vehicle will now be described in what follows with joint reference to Figures 1 to 7. The same elements are identified with the same reference signs throughout the following description.

[0036] The terms "first," "second" (or "firsts," "seconds"), etc., are used in this document by arbitrary convention to allow for the identification and distinction of different elements (such as operations, means, etc.) implemented in the embodiments described below. Such elements may be distinct or correspond to a single element, depending on the embodiment.

[0037] According to a particular and non-limiting embodiment of the present invention, the control of a tilting system for at least one exterior rearview mirror of a vehicle is implemented by one or more vehicle control units, in particular by one or more processors of this or these control units. The vehicle also includes a display system comprising a touchscreen interface, referred to as a touchscreen, controlled by a control unit, for example the vehicle's infotainment system control unit, referred to as an IVI (In-Vehicle Infotainment) control unit.

[0038] Initial data representing the detection of a vehicle parking maneuver are received. This initial data corresponds, for example, to the vehicle being put into reverse. Following the receipt of this initial data, the control unit displays the control button for the tilt system of at least one exterior mirror according to an initial graphic representation. The size of the control button in this initial graphic representation is greater than a predetermined threshold to ensure that the control button is more easily visible and accessible to a vehicle user. Secondary data representing a touch press on the control button is received from the touchscreen interface, for example, when a user touches the touchscreen at the location where the control button is displayed.In response to this second data, third data representing a command to activate the tilt system of at least one exterior mirror is transmitted to a controller of the tilt system of at least one exterior mirror, for example to trigger the tilting of at least one mirror downwards in order to view the edges of a curb.

[0039] Fig. 1 schematically illustrates a part of the passenger compartment of vehicle 10, according to a particular and non-limiting embodiment of the present invention.

[0040] Vehicle 10 corresponds, for example, to a vehicle with an internal combustion engine, with electric motor(s), or even a hybrid vehicle with an internal combustion engine and one or more electric motors. Vehicle 10 thus corresponds, for example, to a land vehicle, for example a car, a truck, a bus.

[0041] The vehicle 10 advantageously incorporates a tilting system for at least one exterior mirror configured to tilt vertically or laterally at least one exterior mirror 11 of the vehicle 10.

[0042] In one embodiment of the present invention, the vehicle 10 includes a manual external mirror adjustment device 13 configured to electrically control the position of the external mirror(s) 11, for example by a plastic rod operated by the driver to adjust the external mirror 11 laterally and / or vertically.

[0043] According to one example, a physical button on the manual exterior mirror adjustment device 13 enables the vertical tilting function of the exterior mirror 11 downwards for visibility of obstacles at ground level. For example, pressing this button positions the exterior mirror(s) 11 in a predefined position, and a second press restores the initial position of the exterior mirror(s) 11.

[0044] The vehicle 10 includes a display system comprising a touch screen interface, referred to as touch screen 12, and a computer configured to control the display of content(s) of a graphical human-machine interface, referred to as HMI, on the touch screen 12. The computer corresponds, for example, to the computer of the infotainment system, referred to as the IVI computer (from the English "In-Vehicle Infotainment" or in French "Infodivertissement étoilé") of the vehicle 10.

[0045] The touch screen 12 corresponds for example to an LCD type screen (from the English "Liquid Crystal Display" or in French "Affichage à cristals liquide"), for example of type TFT (from the English "Thin-Film Transistor" or in French "Transistor en film mince"), or OLED (from the English "Organic Light-Emitting Diode" or in French "Diode électroluminescente organique").

[0046] [Fig.2] schematically illustrates the touch screen 12, according to a particular and non-limiting embodiment of the present invention.

[0047] According to one embodiment, the touchscreen 12 consists of a main display area 21 and a secondary display area 22. For example, the main display area 21 is used to display a set of information for the driver and / or passengers of the vehicle 10, for example, navigation information, or information relating to the operating status of vehicle 10. According to an embodiment illustrated in [Fig.2], the secondary display area 22 is used to display various touch control buttons for vehicle systems 10, for example a tilt system control button for at least one exterior mirror 11 displayed according to a second graphic representation 220.

[0048] According to another embodiment, the touch screen 12 consists of a single main display area 21, occupying the entire available display area of ​​the touch screen 12.

[0049] The touchscreen 12 is configured to display content for the driver and passengers of the vehicle 10. The touchscreen 12 is also configured to allow the driver and / or passengers of the vehicle 10 to interact with one or more systems embedded in the vehicle 10 via a human-machine interface (HMI) displayed on the touchscreen 12. For example, the touchscreen 12 is configured to interact with the IVI system and / or the tilt system of at least one exterior mirror 11 of the vehicle 10.

[0050] The vehicle display system 10 is connected in communication with the tilting system of at least one front exterior mirror 11 of the vehicle 10, for example the computer in charge of the display system (for example the IVI computer) is connected in communication to the computer (also called controller) in charge of the tilting system of at least one exterior mirror 11 via one or more data buses of the vehicle 10's on-board network.

[0051] A problem that arises then concerns the driver of the vehicle 10 pressing a control button for the tilting system of at least one exterior mirror 11, for example, a physical button on the manual exterior mirror adjustment device 13, when a parking maneuver is necessary. This small control button for the tilting system of at least one exterior mirror 11 requires increased precision from the driver of the vehicle 10, while their attention must be focused on the parking maneuver and on perceiving the environment around the vehicle 10.

[0052] Furthermore, in the case of a touch-sensitive activation / deactivation button for the tilting function of the mirrors present on the touch screen 12, this requires navigating through the menus and submenus of a human-machine interface (HMI) displayed on the touch screen 12. Since a parking maneuver generally requires speed of execution, for example to avoid obstructing a traffic lane, this navigation through several menus and submenus slows down the execution of the parking maneuver by the driver of the vehicle 10.

[0053] A process for controlling the tilting system of at least one exterior rearview mirror 11 of the vehicle 10 is advantageously implemented by one or more processors, for example one or more processors of the IVI computer and / or one or more processors of the computer or controller in charge of the tilt system of at least one exterior mirror 11.

[0054] In a first operation of the process, at least one processor of the vehicle 10, for example the IVI computer or a set of computers, receives initial data representative of a parking maneuver detection of the vehicle 10.

[0055] These first data are for example received from a clutch system of the vehicle 10, transmitting information about the engagement of a reverse gear of the vehicle 10. According to another example, the first data represent information about the detection of a stop of the vehicle 10 near a parking space, the proximity information being received from perception sensors of the vehicle 10, of the LIDAR or Radar type.

[0056] In a second operation of the process, illustrated in [Fig.3], the display of a tilt system control button of at least one exterior mirror 11 of the vehicle 10 is controlled in such a way that the button is displayed on the main display area 21 of the touch screen 12 according to a first graphic representation 320, the size of the control button according to the first graphic representation 320 being greater than a first determined threshold.

[0057] The control button is displayed in a determined content of a human-machine interface, called HMI, which content is displayed on the touch screen 12.

[0058] The first graphic representation 320 represents, for example, a rearview mirror with a downward-pointing arrow in its center.

[0059] The fact that the size of the control button according to the first graphic representation 320 is greater than a first determined threshold allows a display easily visible to the driver on the touch screen 12, without diverting his attention.

[0060] A display control of graphic content or any graphic object (text, pictogram, icon, control button, indicator, etc.) includes a rendering of the graphic content or graphic object, such rendering corresponding to a set of operations performed by one or more processors on the pixels of one or more images of the graphic content to be displayed on the touch screen 12. For example, the rendering consists of associating to a set of pixels of an image pixel data (for example color data expressed in an RGB (Red, Green, Blue) type space) associated with each graphic object.

[0061] The display control of the control button according to the first graphical representation thus includes the transmission of control signals to the touch screen 12 to modify the values ​​associated with the pixels of the touch screen 12 at the location intended to display the control button according to the first graphic representation 320 (or any graphic object).

[0062] According to one embodiment, the first threshold represents a ratio between the size of the control button according to the first graphic representation 320 and the total size of the main display area 21 of the touch screen 12. This ratio is expressed as a percentage of the total size of the main display area 21 occupied by the control button according to the first graphic representation 320.

[0063] According to one particular embodiment, the first threshold is equal to 90%. Thus, the control button will be displayed with a size greater than 90% of the size of the main display area 21, as illustrated in [Fig. 3]. A first threshold of 90% makes it easier for the driver to touch the control button without looking at the touchscreen 12, allowing them to remain focused on the maneuver.

[0064] According to another particular embodiment, the first threshold is equal to 50%. Thus, the control button will be displayed with a size greater than 50% of the size of the main display area 21, as illustrated in Figures 4 and 5. For example, a first threshold of 50% makes it easier for the driver to touch the control button, while keeping a display area available on the main display area to show other information useful to the driver for controlling and monitoring the vehicle 10, for example, navigation information, or for example, a video feed from a reversing camera of the vehicle 10.

[0065] According to an embodiment illustrated by [Fig.4], the first graphic representation 420 occupies the left part of the main display area 21 of the screen 12, and the right part of the main display area of ​​the screen 12 is available to display other information.

[0066] According to an embodiment illustrated by [Fig.5], the first graphic representation 520 occupies the upper part of the main display area of ​​the screen 12, and the lower part of the main display area of ​​the screen 12 is available to display other information.

[0067] According to another embodiment, the first threshold represents dimensions in pixels of a height and a width of a minimum rectangular area on which to display the control button.

[0068] According to one embodiment, the first threshold is configurable via a vehicle HMI (Human-Machine Interface) 10. For example, the first threshold is configurable by selecting its value from a menu or page of the HMI. The driver selects the first threshold according to their preferences, for example, a high first threshold if the driver wants to make pressing the control button easier, as shown in the first graphic representation 320, 420, or 520.

[0069] In a third operation of the process, second data representing a touch press on the control button displayed according to the first graphic representation 320, 420 or 520 are received, following a touch press by a user (for example the driver of the vehicle 10) on the control button displayed on the touch screen 12.

[0070] A touch press on the control button displayed according to the first graphic representation 320, 420 or 520 sends information to the IVI computer so that the latter implements one or more functions associated with the command corresponding to the touch press.

[0071] The second data representing the touch press are received for example via one or more data buses linking the touch interface of the screen (or a computer controlling such a touch interface where applicable) and the IVI computer.

[0072] A touch press corresponds to a short or brief touch press in which the duration of the press on the control button is less than a threshold duration (for example, equal to 500 or 1000 ms). According to one embodiment, a touch press corresponds to a long touch press in which the duration of the press on the control button is greater than the threshold duration (for example, equal to 500 or 1000 ms).

[0073] In a fourth operation of the process, the IVI computer transmits third data representing a command or request to activate the tilting system of at least one exterior mirror 11 to the controller of the tilting system of at least one exterior mirror 11, the transmission of the third data being triggered by the reception of the first data by the IVI computer.

[0074] These third data are for example transmitted via one or more data buses linking the IVI computer and a control computer (called controller) of the tilting system of at least one exterior mirror 11.

[0075] The activation command or request activates the tilting system of at least one exterior mirror 11, triggering the downward tilting of the mirror(s) 11 to facilitate parking. This activation allows the driver to decide whether or not to tilt the exterior mirror(s) 11 downwards, depending on the situation, and to avoid unintentional activation of the tilting function if the driver deems this function unnecessary.

[0076] According to one embodiment, the display time of the control button according to the first graphic representation 320, 420, or 520 on the main display area of ​​the touchscreen 12 is a fixed duration. For example, the display time of the control button according to the first graphic representation 320, 420, or 520 on the main display area 21 of the touchscreen 12 is 10, 15, or 20 seconds. The driver has thus a period of time to make the decision to press the control button, for example in the case where the driver has to assess the situation and the environment of the vehicle 10 before making a decision, and therefore requires a delay between the appearance of the control button according to the first graphic representation 320, 420 or 520 and the possibility for the driver to press it.

[0077] According to one embodiment of the present invention, the control button shown in the first graphic representation 320, 420, or 520 on the main display area 21 of the touchscreen 12 disappears upon receipt of the second data. This second data indicates that a touch has been detected on the control button, and it is therefore no longer necessary to display this control button shown in the first graphic representation 320, 420, or 520. In other words, the reception of the second data also triggers a check to end the display of the control button shown in the first graphic representation 320, 420, or 520, the content displayed on the touchscreen 12 then corresponding to the content displayed before the control button shown in the first graphic representation 320, 420, or 520.

[0078] According to another embodiment, the control button shown in the first graphic representation 320, 420, or 520 on the main display area 21 of the touchscreen 12 remains displayed after the second data input has been received. According to this same embodiment, the process further comprises an operation to receive third data input representing a second touch press on the control button, followed by a transmission operation, triggered by the reception of the third data input, of fourth data input representing a command to return the exterior mirror(s) 11 to their initial position to the controller. Since the control button remains displayed on the touchscreen 12 shown in the first graphic representation 320, 420, or 520, the driver can thus quickly and intuitively trigger the return of the exterior mirror(s) 11 to their initial position, for example, at the end of a parking maneuver.

[0079] According to an additional embodiment, the command to return the exterior mirror(s) 11 to an initial position to the controller is automatically transmitted when the end of a maneuver of the vehicle 10 is detected. For example, the detection of the end of a parking maneuver represents the engagement of a forward gear of the vehicle 10, or the shifting of the vehicle 10 into neutral, or for example the detection of an activation of the parking brake of the vehicle 10.

[0080] According to one embodiment, the process further comprises a display control operation for the control button of the tilt system of the exterior mirror(s) 11 on the touch screen 12 according to a second graphical representation 220, and a button size according to the second graphical representation 220 being less than a second threshold, the second threshold being less than the first threshold. This embodiment makes it possible to retain a reduced-size control button available on the touchscreen 12, for example when the control button according to the first graphic representation 320, 420 or 520 disappears from the touchscreen 12.

[0081] According to one embodiment, the display of the control button according to the second graphic representation 220 is carried out on a secondary display area 22 of the touch screen 12.

[0082] The secondary display area 22 corresponds for example to a lower band of the touch screen 12, representing one or more control buttons commanding the activation of one or more systems of the vehicle 10, one of these control buttons being the control button for the tilting system of at least one exterior mirror 11 according to the second graphic representation 220.
