Description

Title of the invention: Method and device for controlling a motorized tailgate opening system of a vehicle. Technical field

[0001] The invention relates to methods and devices for controlling a motorized tailgate opening system of a vehicle, in particular but not exclusively a motor vehicle. The invention relates in particular to a method and a device for controlling the display of a trigger button for a motorized tailgate opening system of the vehicle. Technological background

[0002] Modern vehicles are equipped with a power tailgate opening system configured to open the vehicle's tailgate via a control button. The system generally operates using electric actuators comprising electric motors, which actuate the opening and closing of the tailgate.

[0003] The control of the motorized tailgate opening system is done by manually operating a motorized tailgate opening control device generally located on the vehicle's center console, in the form of a physical button to trigger the motorized tailgate opening system, or in the form of a physical button to trigger the motorized tailgate opening system on a wireless remote control, or in the form of a touch button on a touch screen of the vehicle.

[0004] In certain situations, for example dropping off passengers at an airport terminal or near a railway station, the driver has only a limited time to park on site and allow luggage to be unloaded.

[0005] The control of the power tailgate opening system via a physical button is generally located on a row of physical buttons of similar size and shape, leading to confusion when trying to find the desired button. The driver, who must pay closer attention to their surroundings and the reduced duration of their parking, may have difficulty quickly pressing the physical button to trigger the power tailgate opening.

[0006] Similar difficulties are encountered in the case of a touch-sensitive trigger button present on a vehicle's touchscreen HMI (Human-Machine Interface). This button is generally located in a submenu and requires several successive clicks on the screen to activate it. If the button is present on the HMI's home screen, it is generally situated among other touch buttons. of similar size and shape, requiring increased precision to click the button, and a certain delay to find and press the desired button Summary of the present invention

[0011] Vehicle stop detection allows for the rapid identification of the driver's potential need to open the power tailgate. Displaying a large power tailgate opening system control button on the touchscreen allows for quick and intuitive operation compared to a small physical or touch button, without the driver needing to take their attention away from their surroundings or waste time searching for the button, thus enabling rapid operation of the power tailgate.

[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 one variant, the first threshold is equal to 50%.

[0015] According to another variant, the first threshold is configurable via an HMI (Human-Machine Interface) of the vehicle.

[0016] According to yet another variant, the method further includes a display control step of the control button of the motorized tailgate opening system 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.

[0017] 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.

[0018] According to a second aspect, the present invention relates to a control device for a motorized tailgate opening system of a vehicle, the device comprising a memory associated with a processor configured for the implementation of the steps of the process according to the first aspect of the present invention.

[0019] 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.

[0020] 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.

[0021] Such a computer program may use any programming language, and be in the form of source code, object code, or an intermediate code between source code and object code, such as in a partially compiled form, or in any other desirable form.

[0022] 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.

[0034] A method and a control device for a motorized tailgate opening system 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.

[0035] 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.

[0036] According to a particular and non-limiting example of an embodiment of the present invention, the control of a motorized vehicle tailgate opening system is implemented by one or more vehicle computers, in particular by one or more processors of this or these computers. The vehicle also includes a display system comprising a touchscreen interface, known as a touchscreen, controlled by a computer, for example the computer of the vehicle's infotainment system, known as the IVI computer (from the English "In-Vehicle Infotainment" or in French "Infodivertissement parmi").

[0037] Initial data representing the detection of a vehicle stop is received. This initial data corresponds, for example, to data indicating a zero vehicle speed. Following the receipt of this initial data, the control unit adjusts the display of the power tailgate opening system control button according to a first graphical representation. The size of the control button in this first graphical representation is greater than a predetermined threshold to make the control button more easily visible and accessible to a vehicle user. Second data representing a double touch of the control button is received from the touchscreen interface, for example, when a user performs a double touch on the touchscreen at the display location of the control button. The double touch corresponds, for example, to two successive presses of the button within a limited time interval.In response to this second data, third data representing an activation command for the power tailgate opening system is transmitted to a controller of the power tailgate opening system, for example to trigger the opening of the power tailgate.

[0038] 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.

[0039] 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.

[0040] The vehicle 10 advantageously incorporates a motorized tailgate opening system (or electric tailgate) configured to control the automatic opening or closing of the motorized tailgate of the vehicle 10.

[0041] In one embodiment of the present invention, the vehicle 10 includes a central console with a set of physical buttons, configured to control various functions of the vehicle 10, for example, turning the hazard lights on / off, and turning the air conditioning on or off.

[0042] According to one example, a physical button 11 among the set of physical buttons on the center console allows the opening and closing of the motorized tailgate of the vehicle 10.

[0043] The vehicle 10 includes a display system comprising a touch screen 12 and a computer configured to control the display of content(s) of a graphical human-machine interface, known as an HMI, on the touch screen 12. The computer corresponds, for example, to the computer of the infotainment system, known as the IVI computer (from the English "In-Vehicle Infotainment" or in French "Infodivertissement étoilé") of the vehicle 10.

[0044] 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").

[0045] [Fig.2] schematically illustrates the touch screen 12, according to a particular and non-limiting embodiment of the present invention.

[0046] 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 the vehicle 10. According to an embodiment illustrated in [Fig. 2], the secondary display area 22 is used to display various touch buttons for controlling systems of the vehicle 10, for example a control button for the power tailgate opening system shown according to a second graphic representation 220.

[0047] 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, for example in the case where the central console of the vehicle 10 has a set of physical buttons, not requiring the display of such buttons on the touch screen 12.

[0048] 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 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 power tailgate opening system of the vehicle 10.

[0049] The vehicle display system 10 is connected in communication with the vehicle's motorized tailgate opening system 10; for example, the control unit in charge of the display system (for example, the IVI control unit) is connected in communication to the computer (also called controller) in charge of the motorized tailgate opening system via one or more data buses of the vehicle's on-board network 10.

[0050] A problem that arises then concerns the driver of the vehicle 10 pressing a control button for the power tailgate opening system, either, for example, a physical power tailgate opening button 11 or a touch button displayed according to a second graphic representation 220 on the touchscreen 12, when the power tailgate needs to be opened. The physical power tailgate opening system control button 11 is often small and located in a hard-to-reach area of ​​the center console, for example, at the bottom of the center console. The touch button for the power tailgate opening system is often small and located in a hard-to-reach submenu of the IVI system, requiring a delay to find and activate this control button.

[0051] A control process for the motorized tailgate opening system 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 motorized tailgate opening system.

[0052] 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 detection of a stop of the vehicle 10.

[0053] According to one embodiment, this first data is for example received from a speed sensor of the vehicle 10 or from an odometer of the vehicle 10. This speed sensor measures the current speed of the vehicle 10. For example, the first data corresponds to a speed value of zero, indicating that the vehicle 10 is stopped.

[0054] According to one variant, the first data corresponds to a zero speed value of the vehicle 10, supplemented by information on the unbuckling of the driver's seat belt.

[0055] According to yet another variant, the initial data corresponds to a zero speed value, supplemented by information indicating the proximity of an airport terminal, a railway station, or a metro station. For example, the detection of such a situation comes from data from the vehicle 10's navigation system, or from perception sensor data (video camera, radar, LIDAR) of the vehicle 10.

[0056] According to an additional variant, the first data corresponds to a zero speed value, supplemented by arrival detection information entered into the vehicle navigation system 10, for example by a vehicle geolocation system 10.

[0057] In a second operation of the process, illustrated in [Fig. 3], the display of a control button for the power tailgate opening system is controlled in such a way 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.

[0058] 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.

[0059] The first graphic representation 320 represents, for example, a vehicle with a motorized tailgate in the open position.

[0060] 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, to quickly trigger the opening of the motorized tailgate.

[0061] 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.

[0062] 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% allows the driver to press the control button without looking at the touchscreen 12, in a situation requiring rapid opening of the tailgate, for example, when dropping off a passenger in front of a train station or airport terminal.

[0063] 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 ensuring control and supervision of the vehicle 10, such as a video feed from a reversing camera of the vehicle 10 to monitor the vehicle's surroundings.

[0064] According to an embodiment illustrated by [Fig.4], the first graphic representation 420 occupies the left part of the main display area of ​​the touch screen 12, and the right part of the main display area of ​​the touch screen 12 is available to display other information.

[0065] 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 ​​screen 12 is available to display other information.

[0066] 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.

[0067] 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 a threshold according to their preferences, for example, a high threshold if the driver wants to make pressing the control button easier, as shown in the first graphic representation 320, 420, or 520.

[0068] In a third operation of the process, second data representing a double touch press on the control button displayed according to the first graphic representation 320, 420 or 520 are received.

[0069] A double 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 double touch press.

[0070] The second data representing a double touch press are for example received 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.

[0071] A double touch press corresponds, for example, to two consecutive touch presses on the control button as shown in the first graphic representation 320, 420, or 520 of the power tailgate opening system. The two consecutive touch presses comprise a first press at a first time instant followed by a second press at a second time instant, the time interval between the first and second presses being less than a threshold (for example, 250, 500, or 1000 ms). In other words, the two consecutive presses are performed within a limited time interval that is less than the threshold to be considered as two consecutive presses.

[0072] If two consecutive touch presses are separated by a time interval exceeding the threshold, the power tailgate opening system is not activated by the control button. This double touch press prevents the power tailgate from being accidentally opened.

[0073] In a fourth operation of the process, the IVI computer transmits third data representing a command or request to activate the motorized tailgate opening system to the motorized tailgate opening system controller, the transmission of the third data being triggered by the reception of the second 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 for the motorized tailgate opening system.

[0075] The activation command or request enables the motorized tailgate opening system to be activated, and triggers the motorized tailgate system to automatically open the tailgate to a high position.

[0076] According to one embodiment, the display duration 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 duration of the control button according to the first graphic representation 320, 420, or 520 on the main display area of ​​the touchscreen 12 is 10, 15, or 20 seconds. The driver thus has a period of time to decide whether to press the control button, for example, in the case where the driver of the vehicle 10 needs a reflection period to decide whether to trigger the opening of the power tailgate, and therefore 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 of ​​the touchscreen 12 disappears upon receipt of the second data point. This second data point indicates that a double touch has been detected on the control button, and it is therefore no longer necessary to display this control button in the first graphic representation 320, 420, or 520. In other words, the reception of the second data point 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 was shown in the first graphic representation 320, 420, or 520.

[0078] According to another embodiment, the control button according to the first graphic representation 320, 420, or 520 on the main display area 21 of the touchscreen 12 remains displayed on the screen after the second data point has been received. According to this same embodiment, the process further comprises an operation, following the transmission of the third data point, of receiving fourth data points representing a touch press on the control button according to the first graphic representation 320, 420, or 520, followed by a transmission operation, triggered by the reception of the fourth data point, of fifth data points representing a power tailgate closing command to the power tailgate controller. With the control button remaining displayed on the touchscreen 12 according to the first graphic representation 320, 420, or 520, the driver can thus quickly and intuitively trigger the closing of the power tailgate. for example at the end of the loading / unloading maneuver of the vehicle's trunk 10.

[0079] According to one embodiment, the process further includes a display control operation for the power tailgate opening system control button on the touchscreen 12 according to a second graphical representation 220, the size of the control button 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 maintain a reduced-size control button available on the touchscreen 12, for example, when the control button according to the first graphical representation 320, 420, or 520 disappears from the touchscreen 12.

[0080] 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.

[0081] 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 of the motorized tailgate opening system 10 according to the second graphic representation 220.
