Description

DESCRIPTION Title: Method and device for controlling a vehicle display system comprising a user profile management system Technical field

[0001] The present invention claims priority from French application 2403456 filed on April 4, 2024, the content of which (text, drawings and claims) is incorporated herein by reference.

[0002] 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 a device for controlling the display of information relating to a user profile management system of a vehicle. The invention also relates to a method and a device for assisting in driving a vehicle. Technological background

[0003] Some contemporary vehicles have several screens to display information useful to the driver for driving the vehicle as well as comfort information, such as information for interacting with the vehicle's infotainment system, also called IVI (In-Vehicle Infotainment) system.

[0004] Among these screens, it is known to embed one or more LCD type screens (from the English "Liquid Crystal Display" or in French "Display à cristals liquide"), for example of the TFT type (from the English "Thin-Film Transistor" or in French "Thin film Transistor"), or OLED type (from the English "Organic Light-Emitting Diode" or in French "Organic electroluminescent diode").

[0005] The integration of such screens makes it possible, for example, to control, via a graphical Human-Machine Interface (HMI) displayed on such screens, the operating status of the systems embedded in the vehicle, for example ADAS systems (from the English "Advanced Driver-Assistance System" or in French "Système d'aide à la conduite avance").

[0006] The multiplication of systems on board the vehicle and the multiplication of means of command or control of these systems lead to an increase in complexity of the HM by which a user interacts with the on-board systems to control them, with in particular an increase in icons, displayed messages or command shortcuts, the control and management of which are consequently complicated for a user. The user experience is degraded and the attention of the driver of the vehicle may be reduced when different messages are displayed on the on-board screen(s), which reduces his attention and disrupts the driver's control of the vehicle.

[0007] For example, for vehicles equipped with a user profile management system for one or more users of the vehicle, a warning light is displayed to indicate that a set of vehicle parameters or on-board systems of the vehicle associated with the profile of the user driving the vehicle have been taken into account, for example to adapt the driver's seat settings, the ambient settings, the infotainment system settings according to the selected user profile. Such a warning light is often displayed in a part of a screen intended for the display of numerous warning lights, making the display of the warning light relating to the user profile unclear and sometimes drowned out by a multitude of other warning lights.

[0008] Thus, when the driver of a vehicle asks about this indicator or seeks to obtain information on the selected user profile and / or the user profile management system, the attention required to obtain the information sought leads to safety risks for the vehicle and other road users, the driver's attention being diverted from the road and control of the vehicle's driving may then be impaired. Summary of the present invention

[0009] An object of the present invention is to solve at least one of the problems of the technological background described above.

[0010] Another object of the present invention is, for example, to improve the user experience with respect to a vehicle user profile management system.

[0011] Another object of the present invention is to minimize the loss of driver attention and to improve vehicle safety.

[0012] According to a first aspect, the present invention relates to a method for controlling a display system of a vehicle, the vehicle carrying a system for managing user profiles of a set of users of the vehicle, the display system comprising a touch screen, the method being implemented by a processor and comprising the following steps: - receiving first data representative of an authentication status of a user profile of a user from the set of users; - control of display of a witness representative of the user profile according to the first data for display of the witness in a first zone of the touch screen; - reception of second data representative of a tactile press on the indicator; - control of display of a graphic content determined according to the first data and the second data, the graphic content being displayed in a second zone of the touch screen different from the first zone.

[0013] The direct use of the cookie associated with the user profile management system to request the display of graphic content including information and / or means of controlling parameters of the user profile and / or the user profile management system allows the driver to obtain information simply and on demand, by simply touching the cookie. This reduces the time spent searching for information and / or the effort required to understand what this cookie refers to. The driver is thus less distracted by searching for information and his attention on controlling the trajectory of the vehicle is maximized, which improves the safety of the vehicle and other road users. All content is also displayed on a single screen, making it easier to access information and minimizing the time spent searching for information. This improves driver awareness, as well as the safety of the vehicle and its passengers.

[0014] Centralizing controls on a single screen also eliminates the need for physical buttons to control the user profile management system, reducing vehicle design and manufacturing costs.

[0015] According to a variant, the witness is displayed according to a first graphical representation when the first data is representative of an authentication state corresponding to a first state representative of an unauthenticated state of the user profile and the witness is displayed according to a second graphical representation when the first data is representative of an authentication state corresponding to a second state representative of an authenticated state of the user profile, the second graphical representation of the witness being different from the first graphical representation of the witness.

[0016] According to another variant, the graphic content corresponds to: - a first graphic content when the first data is representative of the first state and when the second data is representative of a tactile press of a duration less than a threshold; - a second graphic content when the first data is representative of the first state and when the second data is representative of a tactile press of a duration greater than the threshold; - a third graphic content when the first data is representative of the second state and when the second data is representative of a touch press of a duration less than the threshold; and - a fourth graphic content when the first data is representative of the second state and when the second data is representative of a touch press of a duration greater than the threshold.

[0017] According to a further variant, the first graphical content comprises a first graphical object configured to require a display of a list of user profiles associated with the set of users by touching the first graphical object and / or a second graphical object configured to select another user profile from the set of users by touching the second graphical object.

[0018] According to an additional variant, the second graphic content comprises a set of third graphic objects configured to modify the list of user profiles and / or configure means of authentication of at least one user profile from the list of user profiles by touching at least one third graphic object from the set of third graphic objects.

[0019] According to yet another variant, the third graphic content comprises a fourth graphic object configured to access a set of information associated with the user profile by touching the fourth graphic object and / or a fifth graphic object configured to access a set of parameters of a mobile application associated with the user profile by touching the fifth graphic object.

[0020] According to an additional variant, the fourth graphic content comprises at least one sixth graphic object configured to require the generation of an access account to at least one other mobile application by touching the at least one sixth graphic object.

[0021] According to a second aspect, the present invention relates to a device for controlling a display system of a vehicle, the device comprising a memory associated with a processor configured for implementing the steps of the method according to the first aspect of the present invention.

[0022] 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.

[0023] According to a fourth aspect, the present invention relates to a computer program which comprises instructions adapted for executing the steps of the method according to the first aspect of the present invention, in particular when the computer program is executed by at least one processor.

[0024] Such a computer program may use any programming language, and may be in the form of source code, object code, or intermediate code between source code and object code, such as in a partially compiled form, or in any other desirable form.

[0025] 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 method according to the first aspect of the present invention.

[0026] On the one hand, the recording medium can be any entity or device capable of storing the program. For example, the medium may include a storage medium, such as a ROM memory, a CD-ROM or a microelectronic circuit type ROM memory, or a magnetic recording medium or a hard disk.

[0027] Furthermore, this recording medium may also be a transmissible medium such as an electrical or optical signal, such a signal being able to be conveyed via an electrical or optical cable, by conventional or hertzian radio or by self-directed laser beam or by other means. The computer program according to the present invention may in particular be downloaded from a network such as the Internet.

[0028] Alternatively, the recording medium may be an integrated circuit in which the computer program is incorporated, the integrated circuit being adapted to perform or to be used in performing the method in question. Brief description of the figures

[0039] A method and device for controlling a vehicle display system will now be described in the following with joint reference to Figures 1 to 8. The same elements are identified with the same reference signs throughout the description which follows.

[0040] The terms "first(s)", "second(s)" (or "first(s)", "second(s)"), etc. are used in this document by arbitrary convention to identify and distinguish 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.

[0041] According to a particular and non-limiting example of embodiment of the present invention, the control of an on-board display system in a vehicle is for example implemented by one or more computers of the vehicle, for example via one or more processors.

[0042] For this purpose, first data representative of an authentication state of a user profile of a user of a set of users having a user profile created via a user profile management system fitted to the vehicle are received, for example from the computer controlling the user profile management system via a data bus. The first data are for example representative of a user profile selected via an HMI of the vehicle or of a default user profile. The authentication state corresponds for example to a first state (authenticated state) or to a second state (unauthenticated state). The display of an indicator representative of the user profile is controlled so that this indicator is displayed in a determined content of a human-machine interface, called HMI, displayed in a first zone of a touch screen of the display system of the vehicle.The cookie corresponds, for example, to a symbol or pictogram representing a user profile, for example an unauthenticated profile or an authenticated profile. The cookie is, for example, displayed in a specific page of the HMI corresponding, for example, to the home screen or the default screen of the HMI, for example in the top banner of such a page.

[0043] Second data representative of a touch press on the indicator are received from the touch interface, for example when a user makes a touch press on the touch screen at the display location of the indicator.

[0044] Following receipt of the second data, the computer controls the display of a particular and determined graphic content in a second zone of the touch screen different from the first zone. The graphic content (and ultimately the information included in this graphic content) is a function of the first data and the second data.

[0045] Such a method makes it possible to control, via a voluntary action, the display of a set of graphic contents comprising information relating to one or more user profiles managed via the user profile management system.

[0046] Figure 1 schematically illustrates a part of the passenger compartment of a vehicle 10, according to a particular and non-limiting exemplary embodiment of the present invention.

[0047] The vehicle 10 corresponds, for example, to a vehicle with a thermal engine, with an electric motor(s) or even a hybrid vehicle with a thermal engine and one or more electric motors. The vehicle 10 thus corresponds, for example, to a land vehicle, for example a car, a truck, a bus.

[0048] The vehicle 10 advantageously incorporates a display system comprising a screen 13 with a touch interface and a computer configured to control the display of content(s) of a graphical MMI on the touch screen 13. The computer corresponds for example to the computer of the infotainment system, called the IVI computer (from the English “In-Vehicle Infotainment” or in French “Infodivertissement embarké”) of the vehicle 10.

[0049] The touch screen 13 corresponds for example to a screen of the LCD type (from the English “Liquid Crystal Display” or in French “Display à cristals liquide”), for example of the TFT type (from the English “Thin-Film Transistor” or in French “Transistor en film mince”), or OLED type (from the English “Organic Light-Emitting Diode” or in French “Diode électroluminescente biologique”).

[0050] The touch screen 13 is configured to display content intended for the driver and passengers of the vehicle 10. The touch screen 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 touch screen 13. For example, the screen 13 is configured to interact with the IVI system and / or a user profile management system of the vehicle 10.

[0051] According to a particular embodiment, the display system comprises 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 seated in the seat 15 sees the content displayed or projected on the transparent blade when the driver drives the vehicle 10. The display system comprises for example furthermore a display screen called a handset or dashboard and generally arranged in an area 12 behind the steering wheel 14 in the dashboard 11.

[0052] According to a particular embodiment, the display system comprising the touch screen 13 is for example provided or configured to reduce the number of screens present in the vehicle 10, making it possible for example to eliminate the display screen(s) called the instrument panel or dashboard.

[0053] According to a particular embodiment, the vehicle 10 has one or more on-board systems each controlled by one or more computers. These computers, with the IVI computer, form for example a multiplexed architecture for the realization of different services useful for the proper functioning of the vehicle and for assisting the driver and / or the passengers of the vehicle in the control of the vehicle 10 via the control of the system(s) embedded in the vehicle 10. The computers communicate and exchange data between them via one or more computer buses, for example a communication bus of the CAN (Controller Area Network) type, CAN FD (Controller Area Network Flexible Data-Rate) or 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).

[0054] An on-board system in the vehicle 10 corresponds to a user profile management system, which system is for example controlled by the IVI computer.

[0055] Such a user profile management system is configured to manage one or more user profiles, for example creating, configuring, deleting, modifying the user profiles of users of the vehicle 10. A user of the vehicle 10 corresponds for example to any person likely to drive the vehicle 10.

[0056] Each user profile of the set of user profiles managed by the user profile management system is associated with a natural person. According to one variant, the system provides for the generation of a so-called guest user profile intended for a person using the vehicle 10 occasionally, or even just once, for example in the company of a regular user of the vehicle 10.

[0057] A user profile includes a set of information associated with the user associated with the user profile, for example: - settings of one or more systems of the vehicle 10, for example the settings of the driver's seat, the mirrors, the infotainment system, the air conditioning system, the interior climate control system, etc.: the selection of a user profile triggers the control of one or more systems according to the settings and parameters recorded in the user profile; and / or - personal information such as the user's name, a photo of the user, an identifier of one or more mobile communication devices 101 or connected object (for example a smartphone, a smartwatch, etc.) configured to connect to the vehicle via a wireless (for example Bluetooth®) or wired (for example USB (Universal Serial Bus)) connection, a password associated with the user profile, etc.; and / or - one or more accounts associated with one or more mobile applications or embedded applications, for example an application for downloading mobile applications (application store developed and managed by a publisher of operating system, for example the App Store® from Apple® or Google Play® from Google®), the purchase of multimedia content, an application published by the vehicle manufacturer 10, etc.

[0058] A user profile can be in one of several states, for example: - a first state corresponding to an unauthenticated state, i.e. a state in which the user associated with the user profile has not identified himself: access to certain functions or services is restricted compared to the access authorized in the authenticated state, for example with a restriction of access to certain mobile applications such as the application store; and - a second state corresponding to an authenticated state, i.e. a state in which the user associated with the user profile has authenticated himself using any means known to those skilled in the art, for example via a certificate recorded on a mobile communication device or a connected object identified at the user profile level, the authentication being automatic when the mobile communication device 101 or a connected object is connected to the vehicle 10 (and to the user profile management system, for example via Bluetooth® or via an identifier and a password recorded at the user profile level: a user profile in the authenticated state allows the associated user to have access to all of the functions or services offered, for example to mobile applications such as an application store.

[0059] A process for controlling an on-board display system in the vehicle 10 is advantageously implemented by one or more processors of the display system, for example by a computer of an on-board system of the vehicle 10 such as the IVI system or the navigation system or by a processor of the mobile communication device.

[0060] In a first operation of the process, first data representative of the authentication status of a user profile of a set of user profiles associated with a set of users are received.

[0061] The user profile corresponds, for example, to a user profile selected when starting the vehicle 10, for example by touching one of the user profiles recorded in the user profile management system.

[0062] In another example, the user profile corresponds to a default user profile (identified as such in the user profile management system) or to the last user profile selected during the last journey made with the vehicle 10.

[0063] According to yet another example, the user profile corresponds to the user profile associated with the mobile communication device 101 (or the connected object) present in the vehicle 10 at the time of starting and connected to the vehicle 10, for example by Bluetooth® or via USB. Such a mobile communication device 101 is identified by the vehicle 10 and the user profile management system as being associated with a user profile recorded during the process of establishing the connection between the mobile communication device 101 and the vehicle 10.

[0064] The authentication status of the profile depends for example on the presence or absence in the vehicle 10 of the mobile communication device 101 allowing the authentication of the user profile and / or the entry of a password by the user when password authentication has been configured and activated for the user profile concerned.

[0065] The authentication state thus corresponds, for example, to the first state representing an unauthenticated state of the user profile or to the second state representing the authenticated state of the user profile.

[0066] In a second operation of the process, the display of a witness representing the user profile or more generally the user profile management system of the vehicle 10 is controlled in such a way that the witness is displayed on the touch screen 13, in a first zone 211 of the touch screen 13, in a determined content of a human-machine interface, called HMI, which content is displayed on the touch screen 13.

[0067] The first area (or part) 211 corresponds for example to an upper band of the screen. The first area 211 corresponds for example to an area known as the status bar, which is provided for the display of a set of indicators and information which remain displayed regardless of the content displayed in the rest of the touch screen 13, that is to say in a second area (or part) 212 of the screen located below the first area 211. The indicators displayed in the first area 211 include for example wireless connection indicators (Wifi®, Bluetooth®, 4G and / or 5G) and the information displayed includes for example the time, the outside temperature, information on the air conditioning system of the vehicle 10, etc.

[0068] The content displayed in the second zone 212 comprises, for example, a set of information useful to the driver for ensuring control and supervision of the vehicle 10. The set of information comprises, for example, the instantaneous speed of the vehicle 10 when the latter is in a rolling or traffic phase, that is to say in motion, driven by the engine of the vehicle 10, a rev counter, for example the remaining range (expressed for example in km), the distance traveled, a volume or level of fuel remaining in the tank when the vehicle 10 comprises a thermal engine, the charge level of the traction battery when the vehicle 10 has a traction battery on board, etc.

[0069] Figures 2 and 3 each illustrate a result of the display control of the indicator in the first zone 211 of the touch screen 13, according to particular and non-limiting exemplary embodiments.

[0070] Figure 2 thus illustrates the witness 21 according to a first graphical representation and Figure 3 illustrates the witness 31 according to a second graphical representation, the witness 21 and the witness 31 both being representative of the user profile and more particularly of the authentication state of the selected user profile but with a different graphical representation, which is a function of the first data received in the first operation and of the authentication state of the selected user profile indicated by the first data.

[0071] The witness 21 is displayed according to a first graphical representation (figure 2) when the first data is representative of an authentication state corresponding to the first state (unauthenticated state) and the witness 31 is displayed according to a second graphical representation (figure 3) when the first data is representative of an authentication state corresponding to the second state (authenticated state), the second graphical representation of the witness 21 being different from the first graphical representation of the witness 31.

[0072] When the authentication state corresponds to the first state (unauthenticated state) illustrated in Figure 2, the witness 21 corresponds to a pictogram representing a person or the bust of a person.

[0073] When the authentication state corresponds to the second state (authenticated state) illustrated in Figure 2, the indicator 31 corresponds to a pictogram representing a person or the bust of a person with a check mark or a hook (corresponding for example to the Unicode and ISO 10646 symbol).

[0074] Of course, the graphic representation of witness 21, 31 is not limited to the above examples but extends to any graphic representation.

[0075] A display control of a witness, graphic content or any graphic object (text, pictogram, icon, etc.) comprises a rendering of the graphic content or the graphic object, such rendering corresponding to a set of operations carried out 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 with a set of pixels of an image pixel data (for example color data expressed in an RGB type space (from the English "Red, Green, Blue" or in French "rouge, vert, bleu")) associated with each graphic object.

[0076] The display control of the indicator 21, 31 thus comprises the transmission of control signals to the touch screen 13 to modify the values ​​associated with the pixels of the touch screen 13 at the location intended to display the indicator 21 (or any graphic object), that is to say at a determined position in the first zone 211.

[0077] The display of the indicator 21, 31 is triggered by the reception of the first indicating in which authentication state the selected user profile is. Thus, each time the authentication state of the selected user profile changes or when a new user profile is selected and depending on the authentication state of the new selected user profile, the display of the indicator 21, 31 is adjusted so that the indicator 21, 31 representing the current authentication state of the selected user profile is displayed in the location provided on the touch screen 13.

[0078] In a third operation, second data representative of a tactile press 201 on the indicator 21 (figure 2) or of a tactile press 301 on the indicator 31 (figure 3) are received, following a tactile press 201, 301 of a user (for example the driver of the vehicle 10) on the indicator 21, 31.

[0079] A tactile press on the indicator 21, 31 sends information to the IVI computer so that the latter implements one or more functions associated with the command corresponding to the tactile press.

[0080] The second data representative of the touch press are for example received via one or more data buses connecting the touch interface of the screen (or a computer controlling such a touch interface where applicable) and the IVI computer.

[0081] Touch support corresponds for example to: - a short or brief tactile press according to which the duration of pressing on the indicator 21, 31 is less than a threshold duration (for example equal to 500 or 1000 ms); or - a long tactile press according to which the duration of pressing on the indicator 21, 31 is greater than the threshold duration (for example equal to 500 or 1000 ms).

[0082] In a fourth operation of the process, the computer in charge of the process, for example the IVI computer, controls the display of a determined graphic content associated with the management of the selected user profile or with the management of all the user profiles of the user profile management system of the vehicle 10. The graphic content displayed is determined according to the first data and the second data. The graphic content is for example selected from a set of graphic contents according to the authentication state of the user profile and according to the nature or type of the touch press (short or long) on ​​the indicator 21, 31.

[0083] The display control of the graphic content is for example triggered by the reception of the second data.

[0084] The fourth operation includes, for example, the transmission of a request by the IVI calculator to the calculator controlling the profile management system users and / or to the IVI system via one or more data buses, to receive the information necessary for displaying the graphic content.

[0085] The graphic content thus corresponds to one of the graphic contents of a set of graphic contents, particular examples of which are described below with reference to figures 4 to 7. The graphic content is displayed in a second zone 212 of the touch screen 13 different from the first zone 211 comprising the indicator 21, 31.

[0086] According to a particular and illustrative embodiment, the second zone is located in the center of the touch screen 13 or in the center of the second zone 212.

[0087] According to a particular example, the graphic content is for example displayed in a window occupying a part of the display area of ​​the screen 13 and included in the second area 212, this window corresponding for example to a contextual window, also called an intrusive or pop-up window.

[0088] According to various particular embodiments of the invention, the graphic content displayed corresponds to: - a first graphic content 41 illustrated in figure 4 when the first data is representative of the first state and when the second data is representative of a tactile press of a duration less than a threshold; - a second graphic content 51 illustrated in figure 5 when the first data is representative of the first state and when the second data is representative of a tactile press of a duration greater than the threshold; - a third graphic content 61 illustrated in figure 6 when the first data is representative of the second state and when the second data is representative of a tactile press of a duration less than the threshold; and - a fourth graphic content 71 illustrated in figure 7 when the first data is representative of the second state and when the second data is representative of a tactile press of a duration greater than the threshold.

[0089] The first graphical content comprises a first graphical object configured to request a display of a list of user profiles associated with the set of users by touching the first graphical object and / or a second graphical object configured to select another user profile from the set of users by touching the second graphical object.

[0090] Figure 4 illustrates an example of a first graphic content 41 comprising a set of graphic objects or pictograms 411, 412, 413, 414 each representing a user profile recorded in the user profile management system. Figure 4 illustrates for example the list of user profiles available in the vehicle 10. The graphic representation of these graphic objects 411, 412, 413, 414 differs from one graphic object to another, for example each graphic object has a different color or each graphic object corresponds to an image of the face of the associated user. The graphic object 411 further comprises the graphic representation of a smartphone to show that the authentication of the associated user profile is configured to be implemented via the connection of a mobile communication device identified in the user profile.

[0091] A touch press 401 on one of these graphic objects, for example the graphic object 413, makes it possible to select the associated user profile.

[0092] The selection of the user profile associated with the graphic object 413 triggers the control of one or more on-board systems to adjust different components of the vehicle 10 (for example the position of the driver's seat via one or more actuators, the ambient lighting of the vehicle 10, etc.) according to the parameters recorded in this user profile.

[0093] Figure 5 illustrates an example of the second graphic content 51 comprising a set of third graphic objects 511 configured to modify the list of user profiles and / or configure authentication means of at least one user profile from the list of user profiles by touching at least one third graphic object from the set of third graphic objects 511. The second graphic content 51 allows the user to access different control parameters of the user profile management system.

[0094] Each third graphic object 511 corresponds for example to a text and / or icon type object identifying the associated function (for example deletion of a profile, modifying a profile, creating a new profile (with association of a mobile communication device) and / or activating manual password authentication.

[0095] A tactile press on one of these third graphic objects 511 triggers for example the display of a particular graphic content (for example in place of the second graphic content) allowing the user to implement the associated function and to fill in the various information necessary for the associated function.

[0096] According to a particular exemplary embodiment, the second graphic content 51 further comprises a pictogram 512 illustrating this second graphic content (for example illustrating that this second graphic content 51 allows access to the parameters of the user profile management system).

[0097] Figure 6 illustrates an example of the third graphical content 61 comprising a fourth graphical object 611 configured to access a set of information associated with the selected user profile by touching this fourth graphical object 611 and / or a fifth graphical object 612 configured to access a set of parameters of a mobile application associated with the user profile by touching the fifth graphical object 612.

[0098] The fourth graphic object 611 and the fifth graphic object 612 each correspond, for example, to a text and / or icon type object identifying the associated function.

[0099] A touch press on the fourth graphic object 611 triggers, for example, the display of new graphic content displaying information associated with a user account (for example an email address) of the profile to access an on-board application published by the manufacturer of the vehicle 10 and offering a set of services developed by the manufacturer.

[0100] A touch press on the fifth graphic object 612 triggers, for example, the display of new graphic content to access the account of the on-board application published by the manufacturer of the vehicle 10, for example to view the associated rights and services.

[0101] Figure 7 illustrates an example of the fourth graphic content 71 comprising at least one sixth graphic object 711, 712 configured to require the generation of an access account to at least one other mobile application by touching the at least one sixth graphic object.

[0102] A touch press on the sixth graphic object 711 triggers, for example, the display of new graphic content for the creation of a new account associated with the user profile to access the on-board application published by the manufacturer.

[0103] A touch press on another sixth graphic object 712 triggers, for example, the display of new graphic content to create one or more new accounts for different mobile or embedded applications (for example applications for accessing social networks, sharing content (for example music), etc.).

[0104] The end of the display of the displayed graphic content (i.e. the first graphic content 41, the second graphic content 51, the third graphic content 61 or the fourth graphic content 71) is controlled by the computer in charge of the process automatically or following an action of the driver or a passenger of the vehicle 10.

[0105] The end of the display of the graphic content is thus, for example, automatically controlled after a determined display duration without any tactile action by the driver or any other user with this graphic content, for example after 5, 10, 15 seconds of display. According to a variant, the end of the display of the graphic content is implemented when the driver makes a brief tactile press on the screen 13 outside the display area of ​​the graphic content.

[0106] Such a process thus makes it possible to do away with any physical button for controlling the user profile management system and allows more intuitive control of the HMI associated with the user profile management system than HMIs requiring navigation through different pages or menus before arriving at the content specific to the user profile management system, via simple touch presses on the indicator 21, 31 and / or on the different graphic contents displayed.
