Description

Title of the invention: Method and device for controlling a set of embedded systems of a vehicle from a screen in the vehicle and a screen on a mobile communication device. Technical field

[0001] The invention relates to methods and devices for controlling a set of embedded systems of a vehicle, in particular but not exclusively a motor 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] The integration of such screens makes it possible, for example, to control, via a graphical Human-Machine Interface (HMI) displayed on such screens, the operation and / or the parameterization of the systems embedded in the vehicle, for example AD AS systems (from the English "Advanced Driver-Assistance System" or in French "Système d'aide à la conduite avancé").

[0005] The proliferation of embedded systems in vehicles and the multiplication of means for commanding or controlling these systems lead to an increased complexity of the user interface (UI) through which a user interacts with the embedded systems to control them. This includes a proliferation of icons, displayed messages, and command shortcuts, the control and management of which are consequently complicated for the user. The user experience is thus degraded, and the driver's attention may be reduced when the driver has to search for which icon to click to control or execute an embedded vehicle system. Summary of the present invention

[0006] One object of the present invention is to solve at least one of the problems of the technological background described above.

[0007] An object of the present invention is, for example, to optimize the control of the embedded systems of a vehicle.

[0008] Another object of the present invention is to minimize the loss of driver attention and to improve vehicle safety.

[0009] According to a first aspect, the present invention relates to a method of controlling a set of systems embedded in a vehicle, the vehicle comprising a display device with a touch interface, referred to as the vehicle touch screen, the method being implemented by at least one processor and comprising the following steps: - receiving data representative of a connection state of a mobile communication device to the vehicle, the mobile communication device comprising a display device with a touch interface, referred to as the mobile communication device touch screen; - distribution of control of the set of on-board systems between the vehicle and the mobile communication device according to the connection state, a first group of on-board systems of the set of on-board systems being controllable from the touch screen of the vehicle and a second group of on-board systems of the set of on-board systems being controllable from the touch screen of the mobile communication device according to the distribution when the connection state corresponds to a connected state representative of a connection between the mobile communication device and the vehicle, the first group of on-board systems and the second group of on-board systems being complementary.

[0010] Distributing control of the vehicle's embedded systems between a touchscreen in the vehicle and a touchscreen on a mobile communication device when the latter is connected to the vehicle simplifies and streamlines the graphical human-machine interfaces (HMIs) used to control these embedded systems. Thus, when the mobile communication device is connected to the vehicle, a portion of the embedded systems can be controlled from the vehicle's touchscreen, while a complementary portion can be controlled from the touchscreen of the mobile communication device. This allows the driver to have two screens for controlling the vehicle's embedded systems, i.e., two screens to display the graphical objects (e.g., icons) that provide access to the control of the embedded systems associated with these graphical objects.This allows the vehicle driver to more easily locate the graphical object to click on, for example, to launch the execution of an associated function. The effort required by the driver to access the control of an on-board system is reduced, and the driver's attention to driving the vehicle is maintained at a high level, which improves the safety of the vehicle, its passengers, and other road users.

[0011] According to one variant, the first group of embedded systems and the second group of embedded systems are controllable from the vehicle's touch screen only when the connection state corresponds to a disconnected state representative of an absence of connection between the mobile communication device and the vehicle.

[0012] According to a further embodiment, the method further comprises the following steps when the connection state corresponds to a connected state: - display control of a first graphic object for each embedded system in the first group on the vehicle's touchscreen, the first graphic object being configured to control at least one function associated with each embedded system in the first group by touching the first graphic object; and - display control of a second graphic object for each embedded system of the second group on the touch screen of the mobile communication device, the second graphic object being configured to control at least one function associated with each embedded system of the second group by touch pressing on the second graphic object.

[0013] According to yet another variant, the method further includes a step of display control of a first graphic object for each embedded system of the first group and the second group on the touch screen of the vehicle, the first graphic object being configured to control at least one function associated with each embedded system of the first group and the second group by touch pressing on the first graphic object when the connection state corresponds to the disconnected state.

[0014] According to an additional variant, the first group of embedded systems comprises: - a vehicle air conditioning system; and - at least one vehicle driver assistance system, known as ADAS system.

[0015] According to a further variant, the second group of embedded systems comprises: - a navigation system; and - an infotainment system.

[0016] According to a second aspect, the present invention relates to a control device for a set of systems embedded in a vehicle, the device comprising a memory associated with a processor configured for the implementation of the steps of the process according to the first aspect of the present invention.

[0017] 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.

[0018] According to a fourth aspect, the present invention relates to a system comprising the vehicle as described above according to the third aspect of the present invention and a mobile communication device configured to be connected to the vehicle via communication.

[0019] According to a fifth 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.

[0020] 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.

[0021] According to a sixth 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.

[0022] 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.

[0023] On the other hand, this recording medium can also be a transmissible medium such as an electrical or optical signal, such a signal being able to be transmitted via an electrical or optical cable, by conventional or radio frequency, by self-directing laser beam, or by other means. The computer program according to the present invention can, in particular, be downloaded from an Internet-type network.

[0024] 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

[0025] Other features and advantages of the present invention will become apparent from the description of the particular and non-limiting embodiments of the present invention below, with reference to the attached Figures 1 to 4, in which:

[0026] [Fig-1] schematically illustrates part of a vehicle passenger compartment, according to a example of a particular embodiment of the present invention;

[0027] [Fig.2] schematically illustrates a screen of the vehicle of [Fig.1] with a mobile communication device, according to a particular embodiment of the present invention

[0028] [Fig.3] illustrates a device configured to control a set of systems embedded in the vehicle of [Fig.1], according to a particular and non-limiting embodiment of the present invention.

[0029] [Fig.4] illustrates a flowchart of the different stages of a control process for a set of systems embedded in the vehicle of [Fig.1], according to a particular and non-limiting embodiment of the present invention. Description of examples of achievements

[0030] A method and a device for controlling a set of systems embedded in a vehicle will now be described in what follows with joint reference to Figures 1 to 4. The same elements are identified with the same reference signs throughout the description that follows.

[0031] 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.

[0032] According to various specific and non-limiting embodiments of the present invention, the control of a set of embedded systems in a vehicle is implemented by one or more vehicle computers, for example via one or more processors, according to a first embodiment, and in combination with one or more processors of a mobile communication device (for example, a smartphone) according to other embodiments. The vehicle includes a touchscreen display device, referred to as the vehicle touchscreen in the following description.

[0033] Data representing the connection state of the mobile communication device to the vehicle are received by the vehicle. The connection state corresponds to a connected state when a wired or wireless link is established between the vehicle and the mobile communication device, or to a disconnected state when no link is established between the vehicle and the mobile communication device. The mobile communication device includes a touchscreen display, referred to as the mobile communication device's touchscreen. Control of all on-board systems is advantageously distributed between the vehicle and the mobile communication device depending on the connection state.Thus, when the connection state corresponds to the connected state, a first group of embedded systems from the set of embedded systems is controllable from the vehicle's touch screen and a second group of embedded systems from the set of embedded systems is controllable from the touch screen of the mobile communication device according to the distribution, the first group and the second group being complementary.

[0034] Thus, in the connected state, control of a first part of the set of embedded systems is accessible from the vehicle's touchscreen, and control of a second part of the set of embedded systems is accessible from the touchscreen of the mobile communication device connected to the vehicle via wired or wireless communication. The second group forming the second part is complementary to the first group forming the first part to form the set of embedded systems. An embedded system of the vehicle belongs to only one group to the exclusion of the other group, i.e., to the first group or the second group, and each embedded system of the vehicle belongs to one group, i.e., to the first group or the second group.

[0035] Fig. 1 schematically illustrates part of a vehicle 10 passenger compartment, according to a particular and non-limiting embodiment of the present invention.

[0036] 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.

[0037] The vehicle 10 is configured to communicate, i.e. to transmit and receive, data with a mobile communication device 101 when the latter is connected in wired communication (for example via a USB connection (from the English "Universal Serial Bus" or "Universal Serial Bus" in French)) or wirelessly (for example via a Wifi® or Bluetooth® type connection) to the vehicle 10.

[0038] The vehicle 10 carries for this purpose a wireless communication system including for example a wired connection interface or module and a wireless communication interface or module, also called a telematic control unit, or TCU (from the English "Telematic Control Unit").

[0039] The vehicle 10 also includes a set of on-board systems, i.e. systems enabling control of the vehicle 10, systems assisting the driver when driving the vehicle 10, systems improving the safety of the vehicle 10 and / or comfort systems to improve the comfort of the driver and passengers during journeys made with the vehicle 10.

[0040] On-board systems adapted for controlling the vehicle 10, for assisting the driver and for improving the safety of the vehicle 10 correspond for example to so-called AD AS systems (from the English “Advanced Driver-Assistance System” or in French “Système d'aide à la conduite avancé”).

[0041] By way of example, these AD AS systems include, for example, the list below not exhaustive: - a speed control system, for example an adaptive cruise control system, also known as ACC (Adaptive Cruise Control), and / or a predictive cruise control, also known as PCC (Predictive Cruise Control); - an electronic stability control system, called ESC (from the English "Electronic Stability Control" or in French "Contrôle électronique de la tranquillité"), DSC (from the English "Dynamic Stability Control" or in French "Contrôle dynamique de la tranquillité") or ESP (from the English "Electronic Stability Program" or in French "Programme électronique de la tranquillité"); - a lane keeping assistance system for the vehicle, called the LKA system (from the English "Lane-Keeping Assist" or in French "Assistant de maintien dans la queue"); - a lane departure warning system, known as the AFIL system; - a traffic sign recognition / reading system, called a TSR system (from the English "Traffic Sign Recognition"); - an automatic headlight activation system; - an automatic windshield wiper activation system; - a driver attention monitoring system; - a pedestrian detection system; - a safety distance alert system, known as an ADS system; - a system for detecting and recognizing ground markings; - a parking assistance system; - an automatic vehicle stop and restart system, known as a STT system (from the English "Start and Stop"); and / or - an audible warning system, known as AVAS (Acoustic Vehicle Alerting System); - a control or supervision system for a component of the vehicle's powertrain, for example the engine, transmission, traction battery for an electric vehicle, etc.

[0042] Other examples of embedded systems are provided below by way of illustration: - an automatic air conditioning system; - a navigation and geolocation system, also called a GNSS system (Geolocation and Navigation by a Satellite System), for example a GPS type system (from the English "Global Positioning System" or in French "Système de géo-positionnement par satellites") or Galileo; - an infotainment system, also called an IVI system (from the English "In-Vehicle Infotainment" or in French "Infodivertissement épâblé"); - an ambient interior lighting system to illuminate the passenger compartment in different colors chosen by the driver; and / or - an electric seat position adjustment system; - etc.

[0043] The vehicle 10 also includes an embedded system corresponding to a display system comprising one or more display devices, for example a touchscreen 12, controlled by a computer configured to control the display of content from a graphical HMI, particularly on the touchscreen 12. The computer corresponds, for example, to the computer of the infotainment system, called the IVI (In-Vehicle Infotainment) computer of the vehicle 10. The connection between the computer and the touchscreen 12 corresponds, for example, to an LVDS (Low Voltage Differential Signaling) type connection. The touchscreen 12 is, for example, located in the dashboard 11 of the vehicle 10.

[0044] The various systems of the vehicle 10, as well as the communication interfaces, are each controlled by one or more computers. These computers form, for example, a multiplexed architecture for providing 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 via the control of the system(s) embedded in the vehicle 10.Computers communicate and exchange data with each other via one or more computer buses, for example a CAN (Controller Area Network), CAN FD (Controller Area Network Flexible Data-Rate), FlexRay (according to ISO 17458), LIN (Local Interconnect Network), or Ethernet (according to ISO / IEC 802-3) type communication bus.

[0045] A control process for a set of embedded systems of the vehicle 10 is advantageously implemented by one or more processors, for example by one or more processors of a computer of the vehicle 10 in association with one or more processors of a mobile communication device 101 according to different implementation examples.

[0046] In a first operation of the process, data representing the connection state of the mobile communication device 101 to the vehicle are received. This data is received, for example, from the computer controlling the vehicle's communication system 10.

[0047] The mobile communication device 101 corresponds for example to a smartphone or a tablet.

[0048] The connection state corresponds, for example, to one of the following states: - a connected state representing a connection between the mobile communication device 101 and the vehicle 10, for example a wired connection such as USB or a wireless connection such as Bluetooth® or Wifi®; or - a disconnected state representing an absence of connection between the mobile communication device 101 and the vehicle 10.

[0049] Data representative of the connected state are received when the vehicle communication system 10 detects the establishment of a wired or wireless link between the mobile communication device 101 and the vehicle communication system 10.

[0050] A wired connection is established when a person connects the mobile communication device 101 to a USB type connector of the vehicle 10.

[0051] The establishment of a wireless link, for example of the Bluetooth® type, is obtained automatically when the radio module of the mobile communication device 101 is activated, and when the mobile communication device 101 has been previously paired with the communication system of the vehicle 10. Pairing is an operation carried out only once (except in the event of loss of pairing), the following connections between the mobile communication device 101 and the communication system of the vehicle 10 being automatic and secure.

[0052] If no communication link is detected between the mobile communication device 101 and the vehicle communication system 10, the connection state is disconnected (default state). The connection state is the default state when no mobile communication device 101 is present in the vehicle 10, when the radio module (e.g., Bluetooth®) of the mobile communication device 101 is not activated (e.g., in inactive mode or airplane mode), or when the mobile communication device 101 has not yet been paired with the vehicle communication system 10.

[0053] In a second operation, depending on the connection state, a distribution of control of a set of embedded systems of the vehicle 10 is implemented by the computer(s) of the vehicle 10 in charge of the process.

[0054] When the connection state corresponds to the connected state, the distribution is as follows: a first group of embedded systems from the set of embedded systems is controllable from the touch screen 12 of the vehicle 10 and a second group of embedded systems from the set of embedded systems is controllable from the touch screen of the mobile communication device 101, the first group and the second group being complementary, that is to say that the complement of the first group in the set of embedded systems corresponds to the second group or equivalently the complement of the second group in the set of embedded systems corresponds to the first group.

[0055] The embedded system(s) in the first group and the embedded system(s) belonging to the second group are the result of a parameter setting of the module, for example, software, controlling the distribution. The list of embedded systems in the first group and the list of embedded systems in the second group correspond, for example, to a default manufacturer's parameter setting. In another example, the list of embedded systems in the first group and the list of embedded systems in the second group are established by a user of the vehicle 10, for example, the driver, via a dedicated HMI, the lists being customizable.

[0056] The complementarity of the first group and the second group implies that each embedded system in the set of embedded systems belongs to one group, either to the first group or to the second group, and that each embedded system in the set of embedded systems belongs to only one group, either to the first group or to the second group.

[0057] When the connected state corresponds to the disconnected state, the distribution is as follows: all the embedded systems of the vehicle's set of embedded systems 10 are controllable from only the touch screen 12 of the vehicle 10, that is to say that the first group of embedded systems and the second group of embedded systems are controllable from the touch screen 12 of the vehicle only, no embedded system of the set of embedded systems being controllable from the touch screen of the mobile communication device 101.

[0058] An embedded system controllable via a touchscreen means that the HMI displayed on this touchscreen allows a user with access to the touchscreen to control this embedded system via the touchscreen interface. Controlling an embedded system includes triggering the execution of one or more functions performed by the embedded system following a user action on the touchscreen, or accessing an HMI settings menu to modify one or more control parameters of the embedded system.

[0059] The first group of embedded systems includes, for example: - a vehicle air conditioning system; and - at least one vehicle driver assistance system, known as ADAS system.

[0060] The second group of embedded systems comprises, by: - a navigation system; and - an infotainment system.

[0061] When the connection state corresponds to the connected state, the process further includes the following operations: - the display control of a first graphic object for each embedded system of the first group on the vehicle's touchscreen, the first graphic object being configured to control at least one function associated with each embedded system in the first group by tapping the first graphic object; and - the display control of a second graphic object for each embedded system of the second group on the touch screen of the mobile communication device, the second graphic object being configured to control at least one function associated with each embedded system of the second group by touch pressing on the second graphic object.

[0062] Fig. 2 illustrates the display of first graphic objects 21 on the touch screen 12 of the vehicle 10 to control the embedded systems of the first group and the display of second graphic objects 22 on the touch screen of the mobile communication device 101 to control the embedded systems of the second group, according to a particular and non-limiting embodiment of the present invention.

[0063] A display control of a witness, 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 touch screen 12 or on the touch screen of the mobile communication device 101. 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.

[0064] The display control of a first graphic object 21 and a second graphic object 22 thus includes the transmission of control signals to the touch screen 12 and the touch screen of the mobile communication device 101 respectively at the location intended to display the first graphic object 21 and the second graphic object 22 respectively.

[0065] The display control of the second graphic objects 22 further includes the transmission of instructions by the vehicle's computer(s) 10 to the mobile communication device 101 via the link connecting them, so that the mobile communication device 101 triggers the display of the second graphic objects 22 and the execution of the associated mobile applications. These instructions include, for example, an identifier for each embedded system to be controlled from the mobile communication device 101.

[0066] A touch press on a first graphic object 21 and a second graphic object 22 sends information to the processor so that the latter implements one or more functions associated with the command corresponding to the touch press.

[0067] Touch press corresponds for example to a short or brief touch press according to which the duration of pressing on the graphic object to trigger the associated execution is less than a threshold duration (for example equal to 500 or 1000 ms).

[0068] A touch press on a first graphic object 21 triggers the transmission of control data to the computer controlling the HMI displayed on the screen 12 and / or to the computer controlling the associated embedded system so that this computer triggers the execution of the associated command.

[0069] The second graphic object 22 corresponds, for example, to an icon or pictogram of a mobile application installed and running on the mobile communication device 101 and corresponding to an embedded system of the vehicle 10. A touch on a second graphic object 22 triggers the transmission of control data to the processor(s) of the mobile communication device 101 to modify, if necessary, the graphic content to be displayed. Alternatively, a touch on a second graphic object 22 triggers the transmission of data to the communication system of the vehicle 10 to trigger the execution of functions or commands by the embedded system of the vehicle 10 controlled via the second graphic object 22.

[0070] For example, if the mobile application corresponds to a navigation application or an infotainment application, the rendering of voice instructions associated with navigation or the rendering of audio content played via the infotainment application is implemented by the vehicle speakers 10 under the control of the system controlling these speakers and receiving the audio data to be rendered from the mobile communication device 101 via the link established between the mobile communication device 101 and the vehicle 10 (via the communication system of the vehicle 10).

[0071] The control of the display of the second graphic objects 22 by the computer(s) of the vehicle 10 is, for example, based on the so-called screen mirroring technology. According to this technology, software modules configured for data communication between the mobile communication device 101 and the vehicle 10 are installed and run on the mobile communication device 101 and the vehicle 10 to manage the data streams received from the mobile communication device 101 and the data streams destined for the mobile communication device 101.

[0072] When the connected state corresponds to the disconnected state, the process further includes a step of displaying a first graphic object for each embedded system of the first group and the second group on the vehicle's touchscreen, the first graphic object being configured to control at least one function associated with each embedded system of the first group and the second group by touching the first graphic object when the connected state This corresponds to the disconnected state. According to this embodiment, no second graphic object is displayed on the touchscreen of the mobile communication device 101. Indeed, since the mobile communication device 101 is not connected to the vehicle 10, the vehicle 10 cannot transmit the instructions necessary to trigger the display of the second graphic objects on the touchscreen of the mobile communication device 101. All of the vehicle 10's onboard systems are controllable from the vehicle 10's touchscreen 12 via the first graphic objects displayed for this purpose on the touchscreen 12.

[0073] Such a process allows the control of the embedded systems to be distributed according to whether the mobile communication device 101 is connected to the vehicle 10 or not. This allows the presence of two touch screens in the vehicle 10 to be taken advantage of when the mobile communication device 101 is connected to the vehicle 10, which brings more clarity in the control of the embedded systems.

[0074] Figure 3 schematically illustrates a device 2 configured to control a set of embedded systems of a vehicle, for example vehicle 10. Device 3 corresponds, for example, to a device embedded in vehicle 10, for example a computer.

[0075] According to a particular embodiment, device 3 corresponds to a mobile communication device such as mobile communication device 101.

[0076] Device 3 is, for example, configured to carry out the operations described opposite Figures 1 and 2 and / or the steps of the process described opposite [Fig. 4]. Examples of such a device 3 include, but are not limited to, embedded electronic equipment such as a vehicle's on-board computer, an electronic control unit such as an ECU (Electronic Control Unit), a smartphone, a tablet, or a laptop computer. The elements of device 3, individually or in combination, can be integrated into a single integrated circuit, into several integrated circuits, and / or into discrete components. Device 3 can be implemented in the form of electronic circuits or software (or computer) modules, or a combination of electronic circuits and software modules.

[0077] The device 3 comprises one (or more) processor(s) 30 configured to execute instructions for carrying out the steps of the process and / or for executing instructions from the software embedded in the device 3. The processor 30 may include integrated memory, an input / output interface, and various circuits known to those skilled in the art. The device 3 further comprises at least one memory 31, corresponding, for example, to volatile and / or non-volatile memory, and / or includes a memory storage device which may include memory volatile and / or non-volatile, such as EEPROM, ROM, PROM, RAM, DRAM, SRAM, flash, magnetic or optical disk.

[0078] The computer code of the embedded software(s) including the instructions to be loaded and executed by the processor is for example stored on memory 31.

[0079] According to various particular and non-limiting embodiments, the device 3 is coupled in communication with other similar devices or systems and / or with communication devices, for example a TCU (Telematic Control Unit), for example via a communication bus or through dedicated input / output ports.

[0080] According to a particular and non-limiting embodiment, the device 3 comprises a block 32 of interface elements for communicating with external devices. The interface elements of the block 32 comprise one or more of the following interfaces: - radio frequency RF interface, for example of the Wi-Fi® type (according to IEEE 802.11), for example in the 2.4 or 5 GHz frequency bands, or of the Bluetooth® type (according to IEEE 802.15.1), in the 2.4 GHz frequency band, or of the Sigfox type using UBN (Ultra Narrow Band) radio technology, or LoRa in the 868 MHz frequency band, LTE (Long-Term Evolution), LTE-Advanced; - USB interface (from the English "Universal Serial Bus" or "Universal Serial Bus" in French); - HDMI interface (from the English "High Definition Multimedia Interface", or "High Definition Multimedia Interface" in French); - LIN interface (from the English "Local Interconnect Network", or in French "Réseau interconnecté local").

[0081] According to another particular and non-limiting embodiment, the device 3 includes a communication interface 33 which enables communication with other devices (such as other computers in the embedded system) via a communication channel 330. The communication interface 33 corresponds, for example, to a transmitter configured to transmit and receive information and / or data via the communication channel 330. The communication interface 33 corresponds, for example, to a wired network of the CAN (Controller Area Network) type, CAN FD (Controller Area Network Flexible Data-Rate), FlexRay (standardized by ISO 17458) or Ethernet (standardized by ISO / IEC 802-3).

[0082] According to a particular and non-limiting embodiment, the device 3 can provide output signals to one or more external devices, such as a display screen 340, touch or not, one or more speakers 350 and / or other peripherals 360 (projection system) via output interfaces 34, 35 and 36 respectively. According to a variant, one or more of the external devices is integrated into the device 3.

[0083] Figure 4 illustrates a flowchart of the different steps in a method for controlling a set of embedded vehicle systems, for example, vehicle 10, the vehicle being equipped with a touchscreen, according to a particular and non-limiting embodiment of the present invention. The method is implemented, for example, by a device embedded in vehicle 10 or by device 3 of Figure 3.

[0084] In a first step 41, data representing a connection state of a mobile communication device to the vehicle are received, the mobile communication device including a display device with a touch interface, referred to as the touch screen of the mobile communication device.

[0085] In a second step 42, the control of the set of embedded systems is distributed between the vehicle and the mobile communication device according to the connection state, a first group of embedded systems of the set of embedded systems being controllable from the touch screen of the vehicle and a second group of embedded systems of the set of embedded systems being controllable from the touch screen of the mobile communication device according to the distribution when the connection state corresponds to a connected state representative of a connection between the mobile communication device and the vehicle, the first group of embedded systems and the second group of embedded systems being complementary.
