Description

Title of the invention: Method and device for controlling a vehicle display system comprising a blind spot monitoring system and a digital rearview system technical field

[0001] The invention relates to methods and devices for controlling a display system of a vehicle, in particular but not exclusively a motor vehicle. The invention relates in particular to a method and device for controlling the display of graphic content related to a blind spot monitoring system (BSM) and / or graphic content related to a digital rear-view system (RNE) of a vehicle. The invention also relates to a method and device for assisting the driver in a vehicle. Technological background

[0002] Contemporary vehicles include, for some of them, several screens to display information useful to the driver for driving the vehicle as well as comfort information, such as, for example, information to interact with the infotainment system, also called IVI system (from the English "In-Vehicle Infotainment" or in French "Infodivertissement étoilé"), of the vehicle.

[0003] Among these screens, it is known to include one or more LCD type screens (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").

[0004] Some vehicles equipped with a digital rear-view system, known as the RNE system, include, for example, a multitude of display screens integrated into the dashboard and / or the trim of the front doors of the vehicle to display both the images received from the external side cameras of the RNE system and all the information and content of the HMI (Human-Machine Interface) necessary for the control of the vehicle.

[0005] The proliferation of embedded systems in the vehicle and the proliferation of means of commanding or controlling these systems lead to a complexification of the 1THM (Thermal Device Management) by which a user interacts with the embedded systems in order to control them, notably with a proliferation of icons, displayed messages or command shortcuts whose control and management are consequently complicated. for a user. The user experience may be degraded and the driver's attention may be reduced when different messages are displayed on the onboard screen(s).

[0006] In addition, the multiplication of display screens embedded in a vehicle as well as the variety of means of command and control of the vehicle's embedded systems increases the price of the vehicle. 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] Another object of the present invention is, for example, to improve the user experience with respect to a blind spot monitoring system and / or a digital rear-view system of a vehicle.

[0009] According to a first aspect, the present invention relates to a method for controlling a display system of a vehicle, the vehicle having a blind spot monitoring system, referred to as the BSM system, and a digital rear-view system, referred to as the RNE system, the display system comprising a touch screen, the method being implemented by at least one processor, the method comprising the following steps: - reception of initial data representative of a command to display a signal indicator representative of the BSM system; - control of the display of the signal indicator in a determined content of a human-machine interface, known as HMI, displayed in a first area of ​​the touch screen following the reception of the first data; - reception of second data representative of a type of first touch press on the signal indicator; - control of display of a first graphic content or a second graphic content in at least a second area of ​​the touch screen different from the first area depending on the second data, the first graphic content being representative of an activation state of the BSM system and the second graphic content being representative of at least one image obtained from at least one camera of the RNE system.

[0010] Direct use of the indicator light representing the BSM system to request the display of either initial graphic content associated with the BSM system or a second graphic content associated with the RNE system allows the driver to obtain additional information or content on demand, simply by touching the indicator light. Both the display of the first graphic content and the display of the second graphic content are controlled via the indicator light, thus reducing the control means required to manage these two systems. Furthermore, all content is displayed on a single screen, which facilitates access to information and minimizes the time spent searching for it. This improves driver vigilance, as well as the safety of the vehicle and its passengers.

[0011] Centralizing controls on a single screen also eliminates the need for physical buttons to control the BSM and RNE systems, thus reducing vehicle design and manufacturing costs.

[0012] According to one variant, the first graphic content is displayed when the second data represents a first short touch press of a duration less than a threshold, and The second graphic content is displayed when the second data represents a first long touch press lasting longer than the threshold.

[0013] According to another variant, when the activation state of the BSM system corresponds to an active state, the first data are representative of the active state of the BSM system, and when the activation state of the BSM system corresponds to an inactive state, the first data are representative of a turn signal activation command on one side of the vehicle.

[0014] According to yet another variant, the first graphic content comprises: - a first graphic object indicating a current activation state of the BSM system; - a second graphical object configured to control a change in the current activation state of the BSM system by touch pressing the second graphical object; and - a third graphical object configured to control a set of BSM system parameters by touch pressing on the third graphical object.

[0015] According to a further variant, the second graphic content is also a function of third data representing the activation of the vehicle's turn signals on a specific side of the vehicle, at least one image being representative: - a right-side view of the vehicle when the third data points are representative of the activation of turn signals on the right side of the vehicle; and - a left side view of the vehicle when the third data points are representative of the activation of turn signals on the left side of the vehicle.

[0016] According to yet another variant, the process further comprises the following steps: - reception of fourth data points representing a touch press on at least one image; - display control of a third graphic content comprising a set of fourth graphic objects configured to control a set of RNE system parameters by touch pressing on at least one fourth graphic object from the set of fourth graphic objects.

[0017] According to an additional variant, the method further comprises the following steps: - receiving fifth data representing a press on the touch screen outside of a display area of ​​the third graphic content; - control of the end of display of the third graphic content following the reception of the fifth data.

[0018] According to another variant, the process further comprises the following steps: - reception of sixth data points representative of a second long touch press of duration exceeding the threshold on the signal indicator; - control of the end of display of the second graphic content following the reception of the sixth data.

[0019] According to a second aspect, the present invention relates to a control device for a vehicle display system, 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.

[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 or a system as described above according to the third 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 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.

[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, or by laser beam self-directed or by other means. The computer program according to the present invention can in particular be downloaded onto 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

[0037] A method and a device for controlling a vehicle display system will now be described in what follows with joint reference to figures 1 to 9. The same elements are identified with the same reference signs throughout the description that follows.

[0038] 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.

[0039] According to a particular and non-limiting example of an embodiment of the present invention, the control of a display system embedded in a vehicle is for example implemented by one or more computers of the vehicle, for example via one or more processors.

[0040] To this end, the display of a signal indicator representing a BSM system is controlled so that this signal indicator is displayed within a specific area of ​​a human-machine interface (HMI), shown in the first zone of a touchscreen of the vehicle's display system. The signal indicator corresponds, for example, to a symbol or pictogram representing the BSM system. The signal indicator is displayed upon receipt of initial data representing a command or request to display the signal indicator. This initial data represents an activation state of the BSM system corresponding to the active or activated state of the BSM system, or, when the BSM system is inactive, the initial data corresponds to turn signal activation data for one side of the vehicle, the activation of the turn signals being initiated, for example, by the vehicle driver via a dedicated control device.

[0041] Second data points representing the first touch press on the indicator light, and more specifically the type of the first touch press, are received from the touch interface, for example when a user touches the touchscreen at the location where the indicator light is displayed. The first touch press is thus, for example, of the short (or brief) type or of the long type.

[0042] Upon receiving the second data input, the computer controls the display of either a first or a second graphic content, depending on the type of the first touch press. The first graphic content represents an activation state of the BSM system, and the second graphic content represents at least one image obtained from at least one camera of the vehicle's digital rear-view system, known as the RNE system.

[0043] Such a method makes it possible to control, via a voluntary action, the display of a set of graphic contents relating to the BSM system or the RNE system.

[0044] Figure 1 schematically illustrates part of the passenger compartment of a vehicle 10, according to a a particular and non-limiting example of the present invention.

[0045] 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.

[0046] The vehicle 10 advantageously incorporates a display system comprising a touchscreen 13 and a computer configured to control the display of content(s) from a graphic HMI on the touchscreen 13. 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.

[0047] The touch screen 13 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").

[0048] The touchscreen 13 is configured to display content for the driver and passengers of the vehicle 10. The touchscreen 13 is also configured to allow the driver and / or passengers of the vehicle to interact with one or more systems embedded in the vehicle via a human-machine interface (HMI) displayed on the touchscreen 13. For example, the screen 13 is configured to interact with the IVI system and / or a blind spot monitoring system, referred to as the BSM system, and / or a digital rear-view system, referred to as the BSM system.

[0049] The screen 13 is for example arranged in the dashboard 11, in a space provided behind the steering wheel 14 according to the point of view of a driver of the vehicle 10 sitting in the driver's seat 15. Such a screen 13 is also called the instrument cluster or dashboard of the vehicle 10.

[0050] According to a particular embodiment, the display system includes one or more other screens, for example a screen of a device or system called a head-up display corresponding, for example, to a transparent or semi-transparent blade arranged in such a way that a driver sitting in the seat 15 sees the content displayed or projected onto the transparent blade when the driver is driving the vehicle 10. The display system further includes, for example, a display screen 12 arranged in a central space of the dashboard 11.

[0051] According to a particular embodiment, the vehicle 10 carries one or more embedded systems, each controlled by one or more computers, including a BSM system and an RNE system. These computers, together with the IVI computer, form, for example, a multiplexed architecture for providing different services useful for the proper functioning of the vehicle and to assist the driver and / or passengers of the vehicle in the control of the vehicle 10 via the control of the system(s) on board the vehicle 10. The computers communicate and exchange data with each other via one or more computer buses, for example a communication bus of the type CAN data bus (from the English "Controller Area Network" or in French "Réseau de contrôlers"), CAN FD (from the English "Controller Area Network Flexible Data-Rate" or in French "Réseau de contrôlers à débit de données flexible"), FlexRay (according to the ISO 17458 standard), LIN (from the English "Local Interconnect Network" or in French "Réseau interconnecté local") or Ethernet (according to the ISO / IEC 802-3 standard).

[0052] Vehicle 10 is thus advantageously equipped with a blind spot monitoring system, known as a BSM system. Such a system is also called a blind spot warning system, or BLIS (from the English "Blind Spot Information System"), or blind spot detection system. This system alerts the driver of a vehicle to the presence of another vehicle located in a blind spot, this other vehicle not being visible from the vehicle's exterior mirrors because it is located in the blind spot. The alert generally takes the form of a warning light arranged in the mirror of each exterior mirror, which illuminates when the presence of the other vehicle is detected in the blind spot.The detection of a vehicle in the blind spot on the left or right of vehicle 10 is obtained, for example, from data received from an object detection sensor such as a radar or sonar arranged, for example, on the rear left corner, respectively right, of vehicle 10. According to one variant, each object detection sensor used for detecting a vehicle in a blind spot corresponds to a camera, for example arranged on each external side mirror of vehicle 10, the lens of each camera being directed towards the rear of vehicle 10 according to the direction of travel of vehicle 10. A blind spot of vehicle 10 corresponds to an area masked from the driver's field of vision of vehicle 10 obtained via the mirrors (interior and exterior) of vehicle 10, i.e. an area that the driver cannot see in the exterior and / or interior mirrors of vehicle 10.

[0053] The vehicle 10 also incorporates a digital rear-view system, known as the RNE system. A digital rear-view system is a system in which each conventional exterior side mirror is replaced by a camera connected to a screen configured to display the images acquired by the camera. Each exterior side camera is, for example, arranged outside the vehicle in place of the mirror and is directed towards the rear of the vehicle to obtain a left side view (via the left camera) and a right side view (via the right camera) of vehicle 10.

[0054] According to an alternative embodiment, the digital rearview system complements, without replacing, the exterior mirror-type side mirrors. In this variant, each exterior mirror-type side mirror (i.e., the left and right exterior side mirrors) is equipped with a camera whose lens is directed towards the rear of the vehicle 10. The images acquired by each camera (left and right) are transmitted to a computer controlling one or more vehicle screens for display on that screen or those screens.For example, images from the left camera are displayed on a left-hand screen in a left-hand area of ​​the vehicle's interior 10, and images from the right camera are displayed on a right-hand screen in a right-hand area of ​​the vehicle's interior 10, each screen (left and right) being visible to the driver seated in the driver's seat 15. In one variant, the control unit for displaying images from the RNE system cameras is further configured to control the display of these images on screen 13 (or on any other screen such as screen 12), as explained in more detail below. In this variant, the display of images on screen 13 either complements or replaces the display of images on the left and right screens provided for this purpose, in which case the vehicle's interior 10 does not include such left and right screens.

[0055] A control process for a display system embedded in the vehicle 10 is advantageously implemented by one or more processors of the display system, for example by one or more processors of one or more computers, for example the computer of the IVI system.

[0056] In a first operation of the process, initial data representative of a command or request to display a signal indicator representative of the BSM system are received.

[0057] This initial data corresponds, for example, to: - initial activation data for the blind spot monitoring function, i.e., initial data representing the active or activated state of the BSM system: when the BSM system is controlled to switch to the active state (for example, by default when starting the vehicle 10 or via a driver command through an HMI (human-machine interface) of the vehicle 10 allowing control of the activation and deactivation of the BSM system), the BSM system, via its control unit, transmits the initial data to the control unit in charge of the process, for example the IVI control unit, so that the latter triggers the display of the warning indicator on the screen, for example on screen 12 or screen 13; or - initial data representative of a turn signal activation command on one side of the vehicle 10, the turn signals being activated by a command from the driver to, for example, signal a change of direction or a change of traffic lane: the control unit controlling the turn signals of the vehicle 10 transmits the first data to the control unit in charge of the process, for example the IVI control unit, so that the latter triggers the display of the signal indicator on the screen, for example on screen 12 or screen 13, as well as a pictogram or indicator representing the activation of the turn signals (for example a flashing arrow oriented towards the side corresponding to the side of activation of the turn signals).

[0058] In a second operation of the process, the display of the indicator light representing the BSM system of the vehicle 10 is controlled in such a way that the indicator light is displayed on the touch screen 13 in a determined content of a human-machine interface, called HMI, which content is displayed on the touch screen 13, following the reception of the first data.

[0059] The displayed content includes, for example, a set of information useful to the driver to ensure the control and supervision of the vehicle 10. The set of information includes, for example, the instantaneous speed of the vehicle 10 when it is in a driving or traffic phase, i.e. in motion, driven by the engine of the vehicle 10, a rev counter, for example the remaining range (expressed for example in kms), the distance traveled, a volume or level of fuel remaining in the tank, etc.

[0060] Fig. 2 illustrates a result of the display control of the signal indicator 21 on the touch screen 13, according to a particular and non-limiting embodiment.

[0061] The signal indicator 21 corresponds for example to a pictogram representing a first vehicle emitting a radar signal (corresponding to vehicle 10) on the left side of this first vehicle and detecting a second vehicle located to the left of the first vehicle behind the first vehicle.

[0062] A warning light 22 is also shown on [Fig.2], this warning light 22 illustrating the activation of the left turn signals of the vehicle 10, this warning light 22 being displayed only when the driver has ordered the activation of the left turn signals.

[0063] This indicator 22 is therefore not always displayed, only indicator 21 being displayed for example when the display of indicator 21 is triggered by the active state of the BSM system (unless the driver requires the activation of the indicators to signal a change of direction).

[0064] When the display of indicator 21 is triggered by the active state of the BSM system (blind spot monitoring function activated), the indicator 21 is displayed as long as the BSM system is in the active state.

[0065] When the display of indicator 21 is triggered by the activation of the turn signals, the indicator 21 is displayed for a predetermined duration (the beginning of which (corresponds to the moment the turn signals are activated), for example for 5 or 10 seconds. According to one variant, the indicator light 21 is displayed as long as the indicator light 22, representing the active state of the turn signals, remains displayed on the screen 13.

[0066] A display control of a signal indicator, graphic content or any graphic object (text, pictogram, icon, 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 screen 13. 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.

[0067] The display control of the signal indicator 21 thus includes the transmission of control signals to the touch screen to modify the values ​​associated with the pixels of the touch screen 13 at the location intended to display the signal indicator 21 (or any graphic object).

[0068] The display of the signal indicator 21 is controlled so that this signal indicator 21 is displayed in a first determined area of ​​the touch screen 13. According to the particular example of [Fig.2], the first area corresponds to an area located at the bottom left of the screen 13, according to the point of view of a person looking at the screen 13 from the driver's seat 15 of the vehicle 10 for example.

[0069] In a third operation, second data representing a first touch 201 on the signal indicator 21 are received, following a touch 201 by a user (for example the driver of the vehicle 10) on the signal indicator 21.

[0070] A touch press on the signal indicator 21 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] The second data points, for example, are more precisely representative of the type of the first touch press 201, the first touch press being of type: - short or brief, that is, a touch contact where the duration of the contact on indicator 21 is less than a threshold duration (for example, equal to 500 or 1000 ms); or - long, that is to say a touch press where the duration of the press on the indicator 21 is greater than a threshold duration.

[0073] According to one variant, an additional type corresponds to a double click, that is a sequence of two consecutive and closely spaced touch presses (with for example less than 250 or 500 ms between the two consecutive touch presses).

[0074] In a fourth operation of the process, the IVI computer controls the display of graphic content in at least a second area of ​​the touch screen 13 different from the first area including the indicator 21, the control of displaying the graphic content being triggered by the reception of the second data.

[0075] The displayed graphic content corresponds to a first graphic content or a second graphic content depending on the second data, according to the type of the first touch 201 signaled in the second data.

[0076] The first graphic content comprises information representing the activation state of the BSM system, and the second graphic content represents one or more images obtained from at least one camera of the RNE system. Each image contained in the second graphic content represents an external side view of the vehicle 10, i.e., a left side view obtained from the left camera of the RNE system or a right side view obtained from the right camera of the RNE system.

[0077] The fourth operation includes, for example, the transmission of a request by the IVI computer to the computer controlling the BSM system and / or the transmission of a request by the IVI computer to the computer controlling the RNE system, via one or more data buses, to receive the information necessary for the display of the first graphic content or the second graphic content, depending on the type of the first touch press 201.

[0078] Fig. 3 illustrates the result of displaying a first graphic content 30 according to a particular embodiment example, the first graphic content being displayed under the control of the computer in charge of the process when the second data are representative of a first short or brief touch 201 on the signal indicator 21.

[0079] According to a particular example, the first graphic content 30 is displayed in a window occupying part of the display area of ​​the screen 13 and corresponding to the second zone, this window corresponding, for example, to a pop-up window, also called an intrusive or pop-up window. This window is, for example, displayed next to the first zone containing the witness 21, for example centered on the screen (around the center of the screen 13).

[0080] The first graphic content 30 illustrated in [Fig.3] comprises: - a first graphic object 31 indicating a current activation state of the BSM system, i.e., the activation state at the moment of the first touch press 201: the first graphic object includes, for example, text indicating the current activation state (active / activated or inactive / deactivated) of the BSM system and / or an icon or a peak a graph illustrating the current activation state; for example, a first display color is associated with the active state (e.g., blue or green) and a second display color is associated with the inactive state (e.g., red or orange); - a second graphic object 32 configured to control a change in the current activation state of the BSM system by touch press 301 on the second graphic object 32: the second graphic object corresponds for example to a radio button or a check box allowing to command or control the transition of the BSM system to the inactive state when the current state corresponds to the active state, and conversely to command or control the transition of the BSM system to the active state when the current state corresponds to the inactive state; the second graphic object includes for example also associated with the radio button to specify or define the parameter or function (i.e. blind spot monitoring) controlled by the radio button;and - a third graphic object 33 configured to control a set of BSM system parameters by touch 302 on the third graphic object 33: the third graphic object 33 corresponds for example to an icon or pictogram representing a cogwheel. ;

[0081] When the current state of the BSM system is the inactive state, if the driver of the vehicle 10 decides to activate the blind spot monitoring function by switching the BSM system to the active state by touching 301 on the second graphic object 32, switching the BSM system to the active state results, for example, in the permanent display of the indicator 21 (until the BSM system returns to the inactive state) in the first area of ​​the screen 13.

[0082] Thus, the first touch press allows information associated with the BSM system to be displayed whenever the driver requests it by a simple touch press on the indicator 21. The first graphic content 30 also allows simple and quick access to the part of the HMI configured to control the BSM system (activation / deactivation and / or modification of system parameters) without having to navigate through the different menus and different pages of the vehicle HMI 10 associated with the control of the different on-board systems of the vehicle 10.

[0083] In additional operations of the process following the display of the first graphic content 30, data representing the touch input 302 on the third graphic object 33 are received. This touch input 302 corresponds, for example, to a short or brief touch.

[0084] Receiving the data representing the touch input triggers the display of a fourth graphic content 40 illustrated in [Fig. 4], the fourth graphic content 40 taking, for example, the place of the first graphic content 30. According to one variant, the fourth graphic content 40 is displayed next to the first graphic content 30. or superimposed, at least partially, on the first graphic content 30.

[0085] This fourth graphic content 40 comprises a set of graphic objects each configured to adjust a parameter of the BSM system.

[0086] The display of this fourth graphic content 40 ends automatically after a predetermined display time without any touch interaction from the driver or any other user with this fourth graphic content 40, for example, after 5, 10, or 15 seconds of display. In one embodiment, the display of the fourth graphic content 40 ends when the driver briefly touches the screen 13 outside the display area of ​​the fourth graphic content 40.

[0087] Similarly, the display of the first graphic content 30 ends automatically after a predetermined display time without any touch interaction from the driver or any other user with this first graphic content 30, for example, after 5, 10, or 15 seconds of display. In one embodiment, the display of the first graphic content 30 ends when the driver briefly touches the screen 13 outside the display area of ​​the first graphic content 30 or when the driver briefly touches the indicator light 21 a second time.

[0088] Figures 5 and 6 each illustrate the result of displaying a second graphic content 50 and 60 according to particular embodiment examples, the second graphic content 50, 60 being displayed under the control of the computer in charge of the process when the second data are representative of a first long touch 201 on the signal indicator 21.

[0089] According to a particular example, the second graphic content 50, 60 is displayed in a window occupying part of the display area of ​​the screen 13 and corresponding to a second area different from the first area, the location of the second area varying according to the second graphic content 50 and 60. This window corresponds for example to a contextual window, also called an intrusive or pop-up window (from the English "pop-up window").

[0090] The display of a second graphic content 50, 60 is controlled according to third data representing the activation of the vehicle's turn signals 10 on a determined side of the vehicle 10. Thus, the content of the images included in the second graphic content 50 and in the second graphic content 60 varies according to the side of activation of the turn signals.

[0091] Thus, each image is representative: - a right-side view of vehicle 10 when the third data points represent the activation of turn signals on the right side of vehicle 10, as illustrated with [Fig. 6] and the second graphic content 60; and - of a left side view of vehicle 10 when the third data are representative of activation of turn signals on the left side of vehicle 10, as illustrated with [Fig.5] and the second graphic content 50.

[0092] According to the example in [Fig.5], the second graphic content 50 is displayed on a left part of the screen 13, for example under the signal indicator 51 for activation of the left turn signals of the vehicle 10.

[0093] This second graphic content 50 is for example displayed in superposition of the graphic content displayed on the screen 13 during the first touch press 201 made on the indicator 21.

[0094] The images displayed in the second graphic content 50 correspond to the images of the left lateral external environment of the vehicle 10 obtained from the left camera of the RNE system, this left camera being arranged and oriented so as to acquire images from the left side of the vehicle 10, towards the rear of the vehicle 10, these images including the blind spot area located to the left of the vehicle 10.

[0095] The display of the second graphic content 50 is triggered by the long touch press 201 on the indicator 21 and by the activation of the left turn signals of the vehicle 10.

[0096] When the display of the signal indicator 21 has been triggered by the active state of the BSM system, the display of the second graphic content 50 requires a command to activate the left turn signals of the vehicle 10 in order to obtain the display of the images of the left view of the vehicle 10.

[0097] When the display of the signal indicator 21 was triggered by the activation command of the left turn signals of the vehicle while the BSM system was in the inactive state, the display of the second graphic content 50 with the display of the images of the left side view of the vehicle 10 is automatic following the long touch press on the indicator 21.

[0098] According to the example in [Fig.6], the second graphic content 60 is displayed on a right part of the screen 13, for example under the signal indicator 61 for the activation of the right turn signals of the vehicle 10. This area in the right part corresponds for example to the symmetrical area of ​​the area in the left part receiving the second graphic content 50 with respect to the center of the screen 13.

[0099] This second graphic content 60 is for example displayed in superposition of the graphic content displayed on the screen 13 during the first touch press 201 made on the indicator 21.

[0100] The images displayed in the second graphic content 60 correspond to the images of the right lateral external environment of the vehicle 10 obtained from the right camera of the RNE system, this right camera being arranged and oriented so as to acquire images from the right side of the vehicle 10, towards the rear of the vehicle 10, these images include the blind spot area located to the right of vehicle 10.

[0101] The display of the second graphic content 60 is triggered by the long touch press 201 on the indicator 21 and by the activation of the right turn signals of the vehicle 10.

[0102] When the display of the signal indicator 21 has been triggered by the active state of the BSM system, the display of the second graphic content 60 requires a command to activate the right turn signals of the vehicle 10 in order to obtain the display of the images of the right view of the vehicle 10.

[0103] When the display of the signal indicator 21 was triggered by the activation command of the right turn signals of the vehicle while the BSM system was in the inactive state, the display of the second graphic content 60 with the display of the images of the right side view of the vehicle 10 is automatic following the long touch press on the indicator 21.

[0104] The end of the display of the second graphic content 50 or 60 is controlled automatically: the display of the second graphic content 50 or 60 is maintained for example as long as the left or right turn signals, respectively, remain activated, the end of the display of the second graphic content 50 or 60 being commanded or controlled with the end of the activation of the left or right turn signals, respectively.

[0105] According to an alternative embodiment, the end of the display of the second graphic content 50 or 60 is implemented when the driver makes a second long touch press on the signal indicator 21, the end of the display being triggered by the reception of the data (called sixth data) representative of this second long touch press on the indicator 21.

[0106] The digital views displayed in each second graphic content 50, 60 complement the side views accessible in the left and right side exterior mirrors of the vehicle 10, with different and very useful information in certain life situations (very heavy traffic, parking maneuver, driving at night or in heavy rain, etc.), at the request of the driver.

[0107] Displaying these images or digital views on the screen 13 also eliminates the need for specific screens for displaying these images.

[0108] In additional operations of the process following the display of the second graphic content 50 or 60, fourth data points representing a touch input on the second graphic content, for example a third touch input 601 on the display area of ​​the second graphic content 60 as illustrated in [Fig. 6], are received from the computer in charge of the process. This touch input 601 corresponds, for example, to a short or brief touch.

[0109] The reception of the fourth representative of the touch press triggers the display of a third graphic content 70, as illustrated in [Fig.7].

[0110] This third graphic content advantageously comprises a set of Fourth graphical objects are configured to control a set of RNE system parameters via touch presses on these fourth graphical objects. For example, a specific RNE system parameter is associated with each fourth graphical object, and a specific parameter is adjusted (or a function activated) via one or more touch presses on the associated fourth graphical object.

[0111] This third graphic content 70 allows, for example, adjusting or setting: - the viewing angle and / or orientation of each camera in the RNE system; and / or - the overlay of information on the images obtained from the cameras; and / or - the brightness of the images obtained from the cameras; and / or - the size of the images displayed; and / or - the zoom level (optical or digital).

[0112] The third graphic content 70 is for example displayed in an area adjacent to the second area receiving the second graphic content 40 or 60, for example in an area around the center of the screen 13.

[0113] According to a particular embodiment, the process further comprises the following operations: - reception of fifth data representing a press on the touch screen 13 outside the display area of ​​the third graphic content 70; - control of the end of display of the third graphic content 70 following the reception of the fifth data.

[0114] According to a variant of this embodiment, the end of the display of the third graphic content 70 is triggered automatically after a determined display time (equal to, for example, 5, 10 or 15 seconds) in the absence of any touch interaction by a user with this third graphic content 70.
