Description

Title of the invention: Method and device for controlling a vehicle display system comprising a mobile telephone 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 a device for controlling the display of information relating to a connection of a mobile telephone system of the vehicle. The invention also relates to a method and a device for assisting in driving a vehicle. Technological background

[0002] Some contemporary vehicles have several screens on board to display information useful to the driver for driving the vehicle as well as comfort information, such as, for example, information for interacting with the infotainment system, also called the IVI system (from the English "In-Vehicle Infotainment" or in French "Infodivertissement embargo"), of the vehicle.

[0003] Among these screens, it is known to embed one or more LCD (Liquid Crystal Display) type screens, for example TFT (Thin-Film Transistor) type, or OLED (Organic Light-Emitting Diode) type.

[0004] 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 the AD AS systems (from the English “Advanced Driver-Assistance System” or in French “Advanced Driving Assistance System”).

[0005] The multiplication of systems embedded in the vehicle and the multiplication of means of command or control of these systems lead to a complexity of 1THM by which a user interacts with the embedded systems to control them, with in particular a multiplication of icons, displayed messages or command shortcuts whose control and management are consequently complicated for a user. The user experience is degraded and the attention of the driver of the vehicle can be reduced when different messages are displayed on the on-board screen(s), which reduces his attention and disrupts the control of the vehicle by the driver.

[0006] For example, for vehicles equipped with a mobile telephone system, also called a telematics system, configured to implement a mobile telephone service via a mobile telephone network, for example via a wireless communication device of the smartphone type, a warning light is displayed when the connection to the mobile telephone network is established or when the wireless communication device is connected to the vehicle, for example via Bluetooth®. 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 unclear.

[0007] Thus, when the driver of a vehicle asks about this indicator or seeks to obtain information on the connection to the mobile telephone network, for example information useful for the mobile telephone service, 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 driving of the vehicle may then be degraded. Summary of the present invention

[0008] An object of the present invention is to solve at least one of the problems of the technological background described above.

[0009] Another object of the present invention is, for example, to improve the user experience with respect to a vehicle mobile telephone system.

[0010] Another object of the present invention is to minimize the loss of attention of the driver and to improve the safety of the vehicle.

[0011] According to a first aspect, the present invention relates to a method for controlling a vehicle display system, the vehicle carrying a mobile telephone system, the display system comprising a touch screen, the method being implemented by a processor and comprising the following steps: - reception of first data representative of a connection from the mobile telephone system; - control of the display of a witness representing the connection in a determined content of a human-machine interface, called HMI, displayed in a first zone of the touch screen; - reception of second data representative of a tactile press on the indicator; - control of display of graphic content comprising a set of graphic objects each representative of information associated with the mobile telephone system according to the second data, the graphic content being displayed in a second zone of the touch screen different from the first zone.

[0012] Direct use of the cookie associated with the type of wireless connection to request the display of graphical content including information relating to a service mobile phone system offered by a vehicle mobile phone system allows the driver to obtain information simply and on demand, by simply touching the indicator. This reduces the time spent searching for information and / or the effort required to understand what the indicator 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, which facilitates access to information and also minimizes the time spent searching for information. This improves the driver's vigilance, as well as the safety of the vehicle and its passengers.

[0013] Centralizing controls on a single screen also eliminates the need for physical buttons to control the mobile phone system, thereby reducing vehicle design and manufacturing costs.

[0014] According to a variant, the method further comprises the following steps: - reception of third data representative of a touch press on a graphic object of the set of graphic objects; - execution control of at least one instruction associated with the graphic object.

[0015] According to a variant, the graphic content corresponds to: - a first graphic content when the second data is representative of a touch press of a duration less than a threshold, the set of graphic objects corresponding to a first set of graphic objects; and - a second graphic content different from the first graphic content when the second data is representative of a touch press of a duration greater than the threshold, the set of graphic objects corresponding to a second set of graphic objects different from the first set of graphic objects.

[0016] According to another variant, the first set of graphic objects comprises a plurality of graphic objects each representative of a tactile link to an entry in a telephone directory.

[0017] According to another variant, the second set of graphic objects comprises a first graphic object representative of a tactile link to a first telephone number associated with a voice mailbox and a second graphic object representative of a tactile link to a second telephone number associated with a determined entry in said telephone directory.

[0018] According to another variant, the indicator is displayed according to a graphic representation depending on a state of the connection.

[0019] According to another variant, the first data is received from a mobile communication device connected in wireless communication to the vehicle.

[0020] According to a second aspect, the present invention relates to a control device of a display system of a vehicle, the device comprising a memory associated with a processor configured to implement the steps of the method according to the first aspect of the present invention.

[0021] 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.

[0022] 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.

[0023] Such a computer program may use any programming language, and 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.

[0024] 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.

[0025] On the one hand, the recording medium may be any entity or device capable of storing the program. For example, the medium may comprise a storage means, such as a ROM memory, a CD-ROM or a microelectronic circuit type ROM memory, or a magnetic recording means or a hard disk.

[0026] 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 an Internet-type network.

[0027] 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

[0036] A method and a device for controlling a display system of a vehicle will now be described in the following with joint reference to Figures 1 to 7. The same elements are identified with the same reference signs throughout the description which follows.

[0037] The terms "first(s)", "second(s)" (or "first(s)", "second(s)"), etc. are used in this document by arbitrary convention to enable different elements (such as operations, means, etc.) implemented in the embodiments described below to be identified and distinguished. Such elements may be distinct or correspond to a single element, depending on the embodiment.

[0038] According to a particular and non-limiting example of embodiment of the present invention, the control of a display system on board a vehicle is for example implemented by one or more computers of the vehicle, for example via one or more processors. The vehicle furthermore has a mobile telephone system configured to establish a wireless connection between the vehicle (for example via a wireless communication device of the vehicle or a mobile communication device communicatively connected to the vehicle) and a mobile telephone network.

[0039] For this purpose, first data representative of a connection of the mobile telephone system (for example a connection between a smartphone and the wireless communication system of the vehicle or a connection between the system of mobile telephony and the mobile telephony network) are received, for example from the vehicle's wireless communication device or from the mobile communication device (for example a smartphone or mobile phone) connected in communication to the vehicle. The display of an indicator representative of the connection 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 vehicle's display system. The indicator corresponds for example to a symbol or pictogram representing a telephone, for example a telephone in wireless communication. The indicator is for example displayed in a determined 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.

[0040] 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.

[0041] Following receipt of the second data, the computer controls the display of graphic content comprising a set of graphic objects each representing information associated with the mobile telephone system in a second zone of the touch screen different from the first zone, as a function of the second data.

[0042] Such a method makes it possible to control, via a voluntary action, the display of a set of graphic contents comprising information relating to the mobile telephone system or to an associated mobile telephone service.

[0043] [Fig. 1] schematically illustrates a wireless communication environment 1 for a vehicle 10, according to a particular and non-limiting exemplary embodiment of the present invention.

[0044] The vehicle 10 corresponds for example to a vehicle with a thermal engine, with 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 an automobile, a truck, a bus.

[0045] The vehicle 10 advantageously carries a mobile telephone system for establishing telephone communications with other mobile telephone devices via a mobile telephone network, for example via the “cloud” 100 (or “nuage” in French) and one or more servers 111 of the “cloud” 100.

[0046] The vehicle 10 corresponds to a so-called connected vehicle, that is to say a vehicle equipped with a communication interface, in particular wireless, for the communication (transmission and / or reception) of mobile telephony data with one or more mobile telephony devices (for example so-called smart mobile telephones (from the English “smartphone”)).

[0047] For this purpose, the vehicle 10 has a wireless communication system on board, comprising, for example, one or more communication antennas connected to a telematic control unit, called a TCU (Telematic Control Unit), itself connected to one or more computers of the on-board system of the vehicle 10. The antenna(s), the TCU and the computer(s) form, for example, a multiplexed architecture for the implementation of various services useful for the proper functioning of the vehicle and for assisting the driver and / or passengers of the vehicle in controlling the vehicle 10.The computer(s) and the TCU communicate and exchange data with each other via one or more computer buses, for example a communication bus of the CAN (Controller Area Network), CAN FD (Controller Area Network Flexible Data-Rate), FlexRay (according to the ISO 17458 standard) or Ethernet (according to the ISO / IEC 802-3 standard) data bus type.

[0048] The vehicle mobile telephone system 10 is configured to connect to a mobile telephone network infrastructure (also called a terrestrial wireless cellular network) via a wireless connection 101.

[0049] According to a first exemplary implementation, the mobile telephone system of the vehicle 10 comprises the wireless communication system of the vehicle 10 communicatively connected to a mobile telephone module of the vehicle 10, which mobile telephone module is configured to connect to the mobile telephone network.

[0050] Such a mobile telephony module comprises an interface for receiving data representative of a subscription to access the mobile telephony network managed or controlled by a mobile telephony operator, called the mobile telephony network operator. The data representative of the subscription are for example stored on a smart card of the SIM card type (from the English "Subscriber Identification Module" or in French "module carrying the identity of the subscriber"), the wireless communication module of the vehicle 10 then comprising an ad hoc smart card reader. According to another example, the data representative of the subscription are stored in an eSIM (from the English "Embedded Subscriber Identification Module" or in French "integrated module carrying the identity of the subscriber"), that is to say a virtualized SIM card, the data of the eSIM being stored in a memory of the wireless communication module of the vehicle 10.

[0051] According to a second example of implementation, the mobile telephone system of the vehicle 10 comprises the communication system of the vehicle connected by wireless communication (Wifi® or Bluetooth® for example) or wired communication (for example of the USB type (from the English “Universal Serial Bus” or “Universal Serial Bus” in French)) to a mobile communication device (for example a smartphone) configured to implement a mobile telephony service. According to this second exemplary implementation, the mobile communication device is configured to access the mobile telephony network managed by the mobile telephony network operator, the mobile communication device comprising the SIM card or the eSIM card. According to this second exemplary implementation, the mobile telephony system of the vehicle 10 comprises the wireless communication device connected to the telematics control unit, the communications with the mobile telephony network (telephony, internet data, etc.) passing through the mobile communication device.

[0052] The infrastructure of the mobile telephone network comprises a set of relay antennas 110 (for example one relay antenna per cell of the cellular network) connected to the “cloud” 100 via a wired connection.

[0053] The mobile telephone network is configured to implement one or more communication standards such as: - 4G corresponding to the LTE standard (from the English “Long Term Evolution” or in French “Evolution à long terme”); - 4G+ corresponding to the LTE-Avanced standard (in French “Advanced Long Term Evolution”); and / or - 5G corresponding to the LTE-Avanced Pro standard (in French “Long-term Evolution Advanced Pro”) or LTE 5G.

[0054] The standard implemented by the mobile telephone network is not limited to one of the standards listed above but extends to any mobile telephone standard known to those skilled in the art such as 3G (or UMTS (from the English "Universal Mobile Telecommunications System" or in French "Universal Mobile Telecommunications System") for the implementation of one or more services based on the use of mobile data (for example voice over IP (from the English "Internet Protocol" or in French "internet protocol"), video over IP, internet data, mobile telephony, etc.).

[0055] [Fig. 2] schematically illustrates a part of the passenger compartment of the vehicle 10, according to a particular and non-limiting exemplary embodiment of the present invention.

[0056] The vehicle 10 advantageously incorporates a display system comprising a screen 23 with a touch interface and a computer configured to control the display of content(s) of a graphical MMI on the touch screen 23. 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 embargo”) of the vehicle 10.

[0057] The touch screen 23 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 "Thin film transistor"), or OLED (from the English "Organic Light-Emitting Diode" or in French "Organic electroluminescent diode").

[0058] The touch screen 23 is configured to display content intended for the driver and passengers of the vehicle 10. The touch screen 23 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 23. For example, the screen 23 is configured to interact with the IVI system and / or the mobile telephone system of the vehicle 10, also called a telematics system.

[0059] 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 25 sees the content displayed or projected on the transparent blade when the driver is driving the vehicle 10. The display system comprises for example furthermore a display screen called a handset or dashboard and generally arranged in an area 22 behind the steering wheel 24 in the dashboard 21.

[0060] According to a particular embodiment, the display system comprising the touch screen 23 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.

[0061] The display system of the vehicle 10 is connected in communication with the mobile telephone system of the vehicle 10, for example the computer in charge of the display system (for example the IVI computer) is connected in communication to the computer in charge of the mobile telephone system (for example the TCU) via one or more data buses of the on-board network of the vehicle 10, or directly to the mobile communication device 26 if the IVI computer comprises a wireless communication interface (for example Bluetooth®).

[0062] A process for controlling a display system on board the vehicle 10 is advantageously implemented by one or more processors of the display system, for example by a computer of the vehicle 10 such as the IVI computer, i.e. by one or more processors of the computer.

[0063] In a first operation of the process, first data representative of a connection of the mobile telephone system are received, for example from the computer controlling the mobile telephone system of the vehicle 10 or from a mobile communication device 26 (for example a so-called mobile and / or smart telephone) connected in communication (wired or wireless) to the mobile telephone system of the vehicle 10 (or to a communication system of the vehicle 10 implementing one or more wireless (for example Bluetooth® or Wifi®) or wired (for example USB) communication interfaces), and therefore to the vehicle 10, for example via one or more data buses of the on-board network connecting the computer implementing the process to the computer of the mobile telephone system.

[0064] The first data are for example representative of a state of the connection, for example: - a connected state; - a disconnected state.

[0065] When the connection to the mobile telephone network is provided by the mobile communication device 26 (which is then part of the mobile telephone system of the vehicle 10), the connection is in the connected state when the mobile communication device 26 is connected to the vehicle 10, for example by Bluetooth® via the wireless communication system of the vehicle 10, and when the connection to the mobile telephone network is established. The connection is in the disconnected state when the mobile communication device 26 is not connected to the vehicle 10 and / or when the connection to the mobile telephone network is not established.

[0066] When the connection to the mobile telephone network is provided directly by the vehicle's mobile telephone system, without going through the mobile communication device 26, i.e. when the vehicle's communication system comprises a mobile telephone module (with SIM or eSIM card), the connection is in the connected state when the connection with the mobile telephone network is established and the connection is in the disconnected state when the connection with the mobile telephone network is not established.

[0067] In a second operation of the process, the display of a witness representing the connection of the mobile telephone system is controlled in such a way that the witness is displayed on the touch screen 23, in a first zone 311 of the touch screen 23, in a determined content of a human-machine interface, called HMI, which content is displayed on the touch screen 23, as illustrated in [Fig. 3] according to a particular exemplary embodiment.

[0068] The first zone 311 corresponds for example to an upper band of the screen. The first zone 311 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 23, that is to say in a second part 312 of the screen located below the first zone 311. The indicators displayed in the first zone 311 include for example other wireless connection indicators (for example of wireless local area networks such as Wifi® or Bluetooth®) and the information displayed includes for example the time, the outside temperature, information on the air conditioning system of the vehicle 10, etc.

[0069] The content displayed in the second zone 312 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 circulation phase, that is to say in motion, driven by the engine of the vehicle 10, a rev counter, for example the remaining autonomy (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.

[0070] The graphical representation of the indicator 31 is for example a function of the state of the connection (connected or disconnected), the graphical representation of the indicator 31 thus graphically illustrating whether the connection to the mobile telephone network is established or not.

[0071] According to an alternative embodiment, the graphic representation of the indicator 31 is for example furthermore a function of one or more events, for example the graphic representation of the indicator 31 varying if a telephone call is in progress or if no telephone call is in progress in the connected state.

[0072] According to another variant, the indicator 31 is only displayed when the connection is in the connected state, that is to say when the connection with the mobile telephone network is established or when the wireless communication device is connected in communication, for example wirelessly (for example Bluetooth®), to the vehicle 10.

[0073] The witness 31 corresponds for example to a pictogram or graphic object representing a telephone, with as a variant a symbol representing a wireless connection.

[0074] 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 23. 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.

[0075] The display control of the indicator 31 thus comprises the transmission of control signals to the touch screen 23 to modify the values ​​associated with the pixels of the touch screen 23 at the location intended to display the indicator 31 (or any graphic object), that is to say at a determined position in the first zone 311.

[0076] The display of the indicator 31 is triggered by the reception of the first data re presentations of the connection. When the graphic representation of the indicator 31 depends on the state of the connection and / or the occurrence of a telephone call in progress, the display of the indicator varies according to the state of the connection and / or the occurrence of a specific event.

[0077] In a third operation, second data representative of a tactile press 301 on the indicator 31 are received, following a tactile press 301 of a user (for example the driver of the vehicle 10) on the indicator 31.

[0078] A tactile press on the indicator 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.

[0079] The second data representative of the touch-sensitive press are for example received via one or more data buses connecting the touch-sensitive interface of the screen (or a computer controlling such a touch-sensitive interface where appropriate) and the IVI computer.

[0080] Touch support corresponds for example to: - a short or brief tactile press according to which the duration of pressing on the indicator 31 is less than a threshold duration (for example equal to 500 or 1000 ms); or - a long tactile press whereby the duration of the press on the indicator 31 is greater than the threshold duration (for example equal to 500 or 1000 ms).

[0081] As described below according to different particular embodiments, a short tactile press on the indicator 31 triggers the implementation by the computer of a first action. A long tactile press on the indicator 31 triggers the implementation by the computer of a second action.

[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, the graphic representation of the graphic content being a function of the second data. The graphic content comprises a set of graphic objects each representative of information associated with the mobile telephone system and / or a mobile telephone service implemented by the mobile telephone system, for example by the mobile communication device 26 connected in communication to the vehicle 10.

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

[0084] The fourth operation comprises, for example, the transmission of a request by the IVI computer to the computer controlling the mobile telephone system, via one or more data buses, to receive the information necessary for displaying the graphic content.

[0085] The graphic content belongs to a set of graphic contents with different graphic representations, particular examples of which are described below. after with regard to figures 4 and 5. The graphic content is displayed in the second zone 312 of the touch screen 23 different from the first zone 311 comprising the indicator 31.

[0086] According to a particular and illustrative embodiment, the second zone is located in the center of the touch screen 23.

[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 23 and included in the second area 312, this window corresponding for example to a contextual window, also called an intrusive or pop-up window (from the English “pop-up window”).

[0088] The graphical representation of the graphical content corresponds to: - a first graphic representation (the graphic content being called first graphic content 41) illustrated in [Fig.4] when the second data is representative of a short tactile press, that is to say of a duration less than a threshold; - a second graphic representation (the graphic content being called second graphic content 51) illustrated in [Fig. 5] when the second data is representative of a long touch press, that is to say of a duration greater than the threshold, the second graphic representation 51 of the graphic content being different from the first graphic representation 41 of the graphic content, at least part of the information contained and displayed in the graphic content according to the second graphic representation 51 being different from the information contained and displayed in the graphic content according to the first graphic representation 4L

[0089] The first graphic content 41 comprises a first set of graphic objects. The second graphic content 51 comprises a second set of graphic objects different from the first set of graphic objects.

[0090] As illustrated in [Fig.4], the first graphic content 41 comprises a first set of graphic objects 411, for example in the form of pictogram(s) 411 or in the form of text(s) or graphic(s) in one or more text zones 412.

[0091] The graphic object 411 corresponds for example to a pictogram representing a telephone reminding that the first graphic content relates to the mobile telephone system of the vehicle 10.

[0092] Zone 412 comprises, for example, a list of graphic objects, each corresponding to a tactile link to an entry in a telephone directory.

[0093] The telephone directory data is for example recorded in a memory of the vehicle 10 or in a memory of the mobile communication device 26 or even in a 111 server of the “cloud” 100.

[0094] The telephone directory data is for example received by the computer implementing the process in the first data, for example from the computer controlling the mobile telephone system of the vehicle 10 or from the mobile communication device 26.

[0095] A telephone directory entry corresponds, for example, to a name of a contact recorded in the telephone directory, a telephone number and possibly other information (for example, an email address or an image of the contact's face or a pictogram representing the contact) being associated with the contact.

[0096] Each graphic object displayed in the area 412 thus corresponds, for example, to a text (for example, the name of the contact) or to a pictogram (for example, the image of the face or the pictogram representing it) associated with the entry in question. A tactile link is also associated with each entry, i.e. the graphic object associated with each entry is clickable.

[0097] According to an alternative embodiment, the pictogram 411 is for example representative of the state of the connection and / or of the detected event (for example call in progress).

[0098] According to another variant embodiment, the first graphic content 41 comprises all or part of the following information (in addition to the telephone directory entries or instead of the telephone directory entries) displayed in the form of graphic objects, in all possible combinations: - information representative of a mobile telephone network operator, for example in the form of text or an operator logo; and / or - information representing a status of the wireless connection, for example a text of the type “Status: connected” or “Status: disconnected”; and / or - information representing a mobile telephone network identification code, for example the MCC code (from the English “Mobile Country Code” or in French “Code pays mobile”), the MNC code (from the English “Mobile Network Code” or in French “Code de réseau mobile”) or a combination of the MMC and MNC codes; and / or - information representing an identification number of the mobile communication device 26 configured to establish the wireless connection, the mobile communication device being connected in communication to the vehicle 10; this information corresponds for example to the IMEI identifier (from the English “International Mobile Equipment Identity” or in French “International Mobile Equipment Identity”); and / or - information representing a signal reception level according to the wireless connection, taking for example the form of a pictogram representing signal reception bars.

[0099] This information is obtained from the mobile telephone system and / or the device mobile communication 26.

[0100] As illustrated in [Fig.5], the second graphic content 51 comprises a second set of graphic objects comprising a first graphic object 511 representative of a tactile link to a first telephone number associated with a voice mailbox and one (or more) second graphic object(s) 512 each representative of a tactile link to a second telephone number associated with a determined entry in the telephone directory (for example a favorite number or the most called telephone number).

[0101] The first graphic object 511 and the second graphic object 512 each correspond to a clickable graphic object, corresponding for example to text, a pictogram, an image, etc.

[0102] According to an alternative embodiment, the second graphic content 51 comprises graphic objects each associated with a parameter of the mobile telephone system to adjust the value or the state of these parameters (for example the volume of a ring tone during an incoming telephone call, the volume during a telephone conversation, the setting for sending an automatic message when an incoming telephone call cannot be taken, etc.

[0103] The end of the display of the graphic content according to the first graphic representation and / or the second graphic representation 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.

[0104] 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, 25 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 23 outside the display area of ​​the graphic content.

[0105] According to a particular embodiment, the process further comprises the following operations: - reception of third data representative of a tactile press on a graphic object of the set of graphic objects, that is to say on a graphic object of the first set of graphic objects when the graphic content displayed corresponds to the first graphic content 41 and a graphic object of the second set of graphic objects when the graphic content displayed corresponds to the second graphic content 51; - execution control of at least one instruction associated with the graphical object.

[0106] For example, according to this embodiment, a touch on a touch link corresponding to an entry in the telephone directory displayed in the first content graphic triggers the execution control of instructions to call the telephone number associated with the input on which the touch was made. The execution control includes for example the transmission of ad hoc instructions to the mobile communication device 26.

[0107] According to another example, a tactile press on the first graphic object 511 triggers the control of execution of instructions to call the telephone number making it possible to reach the voicemail of the mobile telephone service associated with the mobile telephone subscription to listen to any voice messages left on the voicemail, this or these voice messages being played in the passenger compartment of the vehicle 10 via the loudspeakers of the vehicle 10.

[0108] Such a process thus makes it possible to do away with any physical button for controlling the mobile telephone system and allows more intuitive control of the HMI associated with the mobile telephone system than HMIs requiring navigation through different pages or menus before arriving at the content specific to the mobile telephone system, via simple touch presses on the indicator 31 and / or on the different graphic contents displayed.
