Title of the invention: Method and device for wireless communication between a mobile communication device and a vehicle Technical field

[0001] The present invention relates to data communication between a mobile communication device and a vehicle in a wireless communication mode. The present invention relates to methods, devices and systems for wireless communication between a mobile communication device and a vehicle, in particular but not exclusively a motor vehicle. Technological background

[0002] Contemporary vehicles carry one or more screens 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 IVI (In-Vehicle Infotainment) system, of the vehicle. Among these screens, it is known to carry one or more LCD (Liquid Crystal Display) type screens, for example TFT (Thin-Film Transistor) type, or OLED (Organic Light-Emitting Diode) type.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").

[0003] The integration of such screens in the passenger compartment of the vehicle is costly since it is necessary to plan their integration in the passenger compartment, for example in the dashboard, adapt the communication network to connect them to the computer(s) controlling them, develop graphical human-machine interfaces (HMI) allowing vehicle users to interact with the various vehicle systems through these screens, and finally purchase these screens from suppliers. Summary of the present invention

[0004] An object of the present invention is to solve at least one of the problems of the technological background described above.

[0005] Another object of the present invention is to reduce the costs of designing and manufacturing a vehicle.

[0006] Another object of the present invention is to improve the interaction between a user- reader and a set of driver assistance systems.

[0007] According to a first aspect, the present invention relates to a wireless communication method for a wireless communication system comprising a mobile communication device and a vehicle, the method comprising the following steps: - reception, by a processor of the mobile communication device, of first data representative of identification of the vehicle according to a near field communication mode, the first data being received from a radio tag embedded in the vehicle; - execution, by the processor, of a mobile application installed on the mobile communication device, the execution being triggered by the reception of the first data; and - implementation, by the processor, of a wireless connection between the mobile application and the vehicle according to a determined wireless communication protocol.

[0008] Such a method makes it possible to automatically trigger the execution of a mobile application of a mobile communication device when the mobile communication device is in proximity to a radio tag integrated into the vehicle. The mobile application can then be used as a user interface to, for example, interact with the vehicle by communicating data with the vehicle according to the wireless communication protocol of the connection between the vehicle and the mobile application. The mobile communication device can then replace a display screen present in state-of-the-art vehicles, which makes it possible to reduce the cost of the vehicle.

[0009] According to a variant, the execution comprises a control of display of graphical content on a display device of the mobile communication device, the graphical content comprising a set of graphical objects, a service being associated with each graphical object of the set of graphical objects, the set of graphical objects comprising: - a first graphic object representing a telephone service; - a second graphic object representing a navigation service; - a third graphic object representing a service for receiving broadcast audio content; and - a fourth graphic object representing a service for receiving audio content broadcast on the Internet.

[0010] According to another variant, further comprising the following steps: - reception, by the processor, of second data representative of a touch press on a graphic object, called selected graphic object, from the set of graphic objects; - implementation, by the processor, of the service associated with the selected graphic object, the implementation being triggered by the receipt of the second data; - transmission, by the processor, of third data representative of audio content associated with the service according to the determined wireless communication protocol to the vehicle.

[0011] According to another variant, the method further comprises a step of pairing the mobile communication device with the vehicle according to the wireless communication protocol, the pairing being implemented prior to the reception of the first data.

[0012] According to an additional variant, the wireless communication protocol corresponds to the Bluetooth® protocol.

[0013] According to an additional variant, the method further comprises a step of positioning the wireless communication device on a support of the vehicle configured to receive the wireless communication device, the positioning being implemented before receiving the first data.

[0014] According to another variant, the radio tag is integrated into the support.

[0015] According to a second aspect, the present invention relates to a communication device of a wireless communication system comprising a mobile communication device and 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.

[0016] According to a third aspect, the present invention relates to a communication system comprising a device as described above according to the second aspect of the present invention and a vehicle, for example of the automobile type, configured to be connected in wireless communication to the device as described above according to the second aspect of the present invention.

[0017] 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.

[0018] 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.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] 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

[0027] [Fig.4] illustrates a flowchart of the different steps of a method of wireless communication between the mobile communication device and the vehicle of [Fig.l], according to a particular and non-limiting exemplary embodiment of the present invention. Description of the exemplary embodiments

[0028] A method and a wireless communication device for a wireless communication system comprising a mobile communication device and a vehicle will now be described in the following with reference to Figures 1 to 4. Like elements are identified with like reference signs throughout the description which follows.

[0029] 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 to be identified and distinguished. implemented in the embodiments described below. Such elements may be distinct or correspond to a single element, depending on the embodiment.

[0030] According to a particular and non-limiting example of embodiment of the present invention, the control of the communication between a mobile communication device and a vehicle is implemented by one or more processors of the mobile communication device. According to particular embodiments, the control of the communication is implemented by a communication system comprising the mobile communication device and the vehicle, i.e. by one or more processors of the mobile communication device and one or more processors of one or more computers of the vehicle.

[0031] For this purpose, first data representative of identification of the vehicle (for example identifying the make of the vehicle, the type of the vehicle or the vehicle in a unique manner) are received by the mobile communication device according to a near-field communication mode, called CCP (or NFC in English, for "Near-Field Communication"). These first data are received from a CCP radio tag (or "NFC-tag" in English) embedded in the vehicle when the mobile communication device is sufficiently close to this radio tag. The reception of the first data triggers the automatic execution of a mobile application installed on the mobile communication device, this mobile application being configured to serve as a communication interface between the mobile communication device and the vehicle.The execution of the mobile application is accompanied by the implementation of a wireless connection between the mobile application (and more generally the mobile communication device) and the vehicle according to a specific wireless communication protocol, for example Bluetooth®.

[0032] Automatic execution of the mobile application on the mobile communication device (e.g., a smartphone or a tablet) communicating with the vehicle when a NFC radio tag of the vehicle is detected by the mobile communication device allows a user of the vehicle to use the mobile communication device as an interface for controlling a set of useful services during a journey made with the vehicle (e.g., a navigation or infotainment service) in cooperation with certain equipment of the vehicle such as an amplifier and the speakers. The mobile communication device can thus replace a screen usually provided in vehicles to control such services.

[0033] [Fig.l] schematically illustrates a communication system comprising a mobile communication device 101 and a vehicle 10, according to a particular and non-limiting exemplary embodiment of the present invention.

[0034] The vehicle 10 corresponds for example to a vehicle with a thermal engine, electric motor(s) or 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.

[0035] The vehicle 10 carries a communication system configured to communicate with the mobile communication device 101 according to a wireless communication mode.

[0036] For this purpose, the communication system of the vehicle 10 comprises, for example, one or more communication antennas connected to a telematic control unit, called TCU (from the English “Telematic Control Unit”), itself connected to one or more computers of the on-board system of the vehicle 10. The antenna(s), the TCU unit and the computer(s) 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.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.

[0037] The TCU is configured for wireless data communication with the mobile communication device according to a protocol such as Bluetooth® (according to IEEE 802.15.1-2005 or later) or Wifi®, for example Wifi Direct (according to IEEE 802.11, for example according to IEEE 802.1 In or IEEE 802.1 lac).

[0038] The mobile communication device 101 corresponds to a device comprising a display screen, for example a touch screen, and wireless radio communication means configured to communicate with the vehicle 10 according to a wireless communication mode, for example according to the Bluetooth® or Wifi® protocol, for example Wifi Direct, as known to those skilled in the art.

[0039] The mobile communication device 101 thus corresponds, for example, to a smartphone or a touchscreen tablet.

[0040] The screen of the mobile communication device 101 is for example associated with a touch interface and 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”).

[0041] A set of mobile applications are installed on the communication device mobile communication device 101 so that the latter can execute each of these mobile applications. The mobile applications are each configured for the implementation of one or more services such as for example a navigation service (application of the Waze® or Google® Maps® type), a service for receiving broadcast audio content (radio application provided for the Android® or iOS® system), a service for receiving audio content broadcast according to the internet protocol (web radio type application provided for the Android® or iOS® system). The mobile communication device 101 thus comprises means configured for the reception of broadcast analog or digital audio content such as antennas and a radio tuner, means configured for the reception of broadcast audio content according to the internet protocol such as antennas, an internet connection interface, for example using a 4G or 5G LTE type connection.

[0042] The vehicle 10 carries a support 12 associated with the dashboard 11, which support is configured and adapted to support and hold the mobile communication device 101.

[0043] The support 12 is adapted to hold the mobile communication device 101 to allow a user installed in the passenger compartment of the vehicle 10 to see the screen of the mobile communication device 101. The support 12 is thus configured to hold the mobile communication device 101 in a vertical or essentially vertical position, the screen of the mobile communication device 101 facing one or more passengers of the vehicle 10, for example the driver of the vehicle 10 and the front passenger. According to a variant, the support 12 is also configured to hold the mobile communication device 101 in a horizontal or essentially horizontal position.

[0044] The support 12 is for example integral with the dashboard 11 forming an integral part of the dashboard 11. According to a variant, the support 12 is an accessory added to the vehicle 10 and fixed to the dashboard 11 according to any method known to those skilled in the art, for example by gluing or by screwing onto the dashboard. According to another variant, the support 12 is fixed to the dashboard 11 in a detachable manner, by any means known to those skilled in the art, for example by suction cup.

[0045] The support 12 comprises a housing configured to receive the mobile communication device 101. The housing corresponds for example to a generally U-shaped space, with a face forming the bottom of the space on which the back of the mobile communication device 101 is applied, this face having a determined height (for example equal to a few centimeters) corresponding to the height of the support 12 for example. The housing is closed on its sides by two side walls, at least one of which is movable in translation relative to the other to adapt the dimensions of the space available between these two walls to receive the mobile communication device 101. The walls form a vice for clamping the mobile communication device 101.

[0046] Such a support 12 thus makes it possible to hold the mobile communication device 101 in position in a stable manner. The space between the side walls being adjustable, this makes it possible to adjust the clamping force on the mobile communication device 101 and to receive mobile communication devices of different dimensions, in particular of different widths.

[0047] According to another exemplary embodiment of the support, the support corresponds to a magnetic support configured to receive the mobile communication device 101 then provided with a metal plate on the face opposite the screen.

[0048] According to a particular embodiment of the support 12, a button 121 is provided in a space arranged near the housing receiving the mobile communication device 101. This button 121 is configured to trigger a pairing operation of the mobile communication device 101 with the vehicle 10 (for example as provided in the Bluetooth® standard) during the first connection of the mobile communication device 101 to the vehicle 10. The triggering of the pairing operation is obtained by activating the button 121, that is to say by pressing the button 121. The button 121 comprises for example an LED type light indicator lighting up in a fixed or intermittent manner when the button 121 is pressed and the pairing operation is in progress. The indicator light flashes, for example, when the pairing operation is in progress, and the indicator light then becomes solid when the pairing operation is successfully completed.

[0049] A CCP or NFC radio tag is advantageously embedded in the vehicle 10, for example inserted into the material of the support 12 or in the dashboard 11. The CCP radio tag is located in the vehicle 10 in such a way that this radio tag is at a distance less than a threshold (for example less than 5 or 10 cm) from the back of the mobile communication device 101 when the latter is placed in position in the support 12.

[0050] The mobile communication device 101 comprises a CCP radio tag reader configured to read the data stored on the CCP radio tag. The CCP radio tag reader is a communication device advantageously comprising an antenna, called a primary antenna, associated for example with a transmitter and a microcontroller.

[0051] Near-Field Communication (NFC) is based on short-range, high-frequency wireless communication technology, for example 13.56 MHz. Such technology allows the exchange of information between devices up to a distance of a few centimeters, for example 5 or 10 cm.

[0052] The data stored on the CCP radio tag correspond to or include first data representative of identification of the vehicle 10. This first data corresponds for example to: - vehicle brand identification data 10; or - identification data of a type of the vehicle 10, for example the category of the vehicle 10, its equipment level, its engine, etc., for example in addition to the brand; or - unique identification data of the vehicle 10, for example the VIN (Vehicle Identification Number) of the vehicle 10.

[0053] A wireless communication process between the mobile communication device 101 and the vehicle 10 is advantageously implemented by one or more processors of the mobile communication device 101. According to particular embodiments, certain operations of the process are implemented by one or more processors of one or more computers of the vehicle 10. According to these particular embodiments, the process is implemented by a communication system comprising the vehicle 10 and the mobile communication device 101.

[0054] In a first operation of the process, a pairing of the mobile communication device 101 with the vehicle 10 is implemented.

[0055] The pairing operation corresponds for example to an operation prior to the communication process, such pairing being known to those skilled in the art.

[0056] Pairing is implemented according to a determined wireless communication protocol or standard, for example Bluetooth®.

[0057] Pairing allows the association between two terminals, that is to say between the vehicle 10 and the mobile communication device. In Bluetooth®, link keys, making it possible to secure the communication channels between the two terminals, are created during pairing.

[0058] The pairing corresponds for example to a secure simple pairing, which is based on a secret shared by the Diffie-Hellman algorithm where the link key is generated from this shared secret.

[0059] Such pairing comprises the following operations: - exchange of input / output parameters; - exchange / sharing of the secret according to the Diffie-Hellman algorithm; - first authentication of the terminals with an association of the terminals, for example according to the so-called “just work” model or by the exchange of cryptographic data for the creation of the keys via CCP (the vehicle 10 then comprising a CCP radio-tag reader to read the data identification stored on a NFC radio tag of the mobile communication device); - creation of link keys from the shared secret; - second authentication by verifying that the 2 terminals share the same link key; and - creation of an encryption key if the option is activated, to secure the communication of data between the vehicle 10 and the mobile communication device 101.

[0060] Such pairing is known and is for example described in the document entitled “Bluetooth Secure Simple Pairing with enhanced security level”, by Samta Gajbhiye et al., published in 1999 in “Bluetooth specification 1.0”.

[0061] Pairing is for example triggered following a press on button 121.

[0062] According to another example, the pairing is triggered automatically by bringing the mobile communication device 101 close to the support 12, the pairing being triggered by the detection of the radio tag of the device 101 by the radio tag reader (called CCP reader or NFC reader) of the vehicle 10.

[0063] Pairing is a one-time operation (except in the event of loss of pairing), with subsequent connections between the mobile communication device 101 and the vehicle 10 being automatic and secure.

[0064] In a second operation of the process, if the mobile communication device 101 is not arranged on the support 12, the wireless communication device 101 is positioned on the support 12 of the vehicle 10, for example by the driver or a passenger of the vehicle 10.

[0065] In a third operation of the process, the mobile communication device 101 detects the CCP radio tag of the vehicle 10, which CCP radio tag is inserted into the support 12 or into the dashboard 11 at a distance less than a threshold distance (the threshold distance being for example equal to 5 or 10 cm) from the mobile communication device 101 when the latter is positioned on the support 12.

[0066] Once the radio tag is detected, the processor(s) in charge of the processor receives or receives the first data representative of identification of the vehicle according to the near field communication mode (CCP or NFC), the first data being received automatically from the radio tag of the vehicle.

[0067] The first data are automatically read by the NFC reader of the mobile communication device 101 when the latter is at a distance less than the threshold distance from the radio tag, then collected by the processor(s) of the mobile communication device 101 for processing.

[0068] In a fourth operation of the process, the vehicle 10 is identified by the mobile communication device 101 via the first data, which triggers the automatic execution of a determined mobile application already installed on the mobile communication device 101.

[0069] If the mobile application is not already installed, a message is displayed on the screen of the mobile communication device offering the user of the mobile communication device to download and install it. The downloading and installation of the mobile application are implemented following validation by the user.

[0070] The mobile application corresponds for example to a mobile application developed and offered for downloading by the manufacturer of the vehicle 10, by a supplier of the vehicle 10 (called OEM, from the English “Original Equipment Manufacturer” or in French “Manufacturer of original equipment”) or by a third party (for example licensed by the manufacturer of the vehicle 10).

[0071] In a fifth operation of the process, a connection between the mobile application and the vehicle 10 is implemented in parallel with the execution of the mobile application, relying on the wireless communication interface (or system) of the mobile communication device 101, according to the Bluetooth® wireless communication protocol (or Wifi® according to another exemplary embodiment).

[0072] The mobile communication device 101 and the vehicle 10 having previously been paired according to the wireless communication protocol implemented, the wireless connection is implemented automatically, without intervention from the driver or a passenger of the vehicle 10.

[0073] The implementation of such a connection allows the mobile communication device 101 to transmit (or exchange according to a bidirectional communication mode) data to the vehicle 10 in a secure manner, benefiting from the security options of the protocol implemented, in particular Bluetooth®, such as data encryption.

[0074] The mobile application thus executed is configured to serve as a control interface for the driver and / or passengers for the implementation of various services, in particular within the framework of a journey made with the vehicle 10.

[0075] The mobile application is intended to implement these different services and / or to serve as an interface with other mobile applications installed on the mobile communication device 101.

[0076] These different services include, for example, infotainment type services (playing of different contents including audio contents, with their downloading if necessary), navigation system type services (with route calculation and provision of instructions for following this route). According to a variant, these different services include services for controlling a set of on-board systems of the vehicle 10 with the transmission of commands to this or these on-board systems, for example the control of an air conditioning system of the vehicle 10.

[0077] The execution of the mobile application comprises for example the control of display of graphical content on the screen (called display device) of the mobile communication device 101. Such graphical content forms for example a home page of the graphical user interface associated with the mobile application.

[0078] The graphic content comprises a set of graphic objects each associated with a specific service.

[0079] Display control includes rendering of the graphic content, such rendering corresponding to a set of operations performed by one or more processors on the pixels of each image displayed on the screen to compose the graphic content. For example, rendering consists of associating with a set of pixels of the image pixel data (for example color data expressed in an RGB (Red, Green, Blue) type space) associated with each graphic object forming the graphic content.

[0080] Each graphic object corresponds to a graphic element obtained by image synthesis.

[0081] [Fig.2] illustrates an example of the result of rendering such graphical content on the screen of the mobile communication device.

[0082] According to the example of [Fig.2], the graphic content includes: - a first graphic object 21 representative of a telephone service; - a second graphic object 22 representative of a navigation service; - a third graphic object 23 representative of a service for receiving broadcast audio content; and - a fourth graphic object 24 representing a service for receiving audio content broadcast on the Internet

[0083] A fifth graphic object 25 is for example further rendered and displayed in the graphic content to signal to the driver and / or passengers of the vehicle 10 that the connection between the mobile communication device 101 and the vehicle 10 is established. The fifth graphic object 25 corresponds for example to a pictogram associated with the communication protocol implemented, for example the Bluetooth® protocol according to the particular example of [Fig.2].

[0084] Other graphical information is for example included in the graphical content, for example the date of the day, the time, graphical objects to access other graphical content of the mobile application, a menu, etc.

[0085] A touch pressure at the display location of one of the graphic objects 21 to 24 makes it possible to trigger the execution or implementation of the associated service.

[0086] Thus, the reception of second data representative of a touch press on a graphic object, called selected graphic object, from the set of graphic objects 21 to 24 triggers the implementation of the service associated with the selected graphic object.

[0087] The implementation of the associated service comprises, for example, the automatic execution of a mobile application associated with the graphical object considered or the display of a new page (or new graphical content) of the graphical user interface associated with the mobile application, this new page being associated with the service associated with the selected graphical object.

[0088] A tactile press on the first graphic object 21 triggers the telephony service, for example for dialing a number to call or selecting a contact to call.

[0089] A touch press on the second graphic object 22 triggers the navigation service, for example to enter a destination of a journey to be made and trigger the calculation of one or more possible routes.

[0090] A tactile press on the third graphic object 23 triggers the radio service (for example the digital radio broadcasting service, called DAB (from the English “Digital Audio Broadcasting” or the analog radio broadcasting service in frequency modulation, called FM) for the reception of audio contents.

[0091] A touch press on the fourth graphic object 24 triggers the internet radio service to access audio content broadcast by web radios according to the internet protocol.

[0092] The mobile application thus offers a simplified interface to the driver (and / or passengers) of the vehicle 10 to access a set of specific services. A limited number of services offered improves the readability of the interface and facilitates its use.

[0093] Such a mobile application makes it possible to use the screen of the mobile communication device 101 as a user interface instead of a display device integrated into the dashboard 11 in state-of-the-art vehicles. This thus makes it possible to dispense with such a display device integrated into the vehicle 10, which reduces the cost of the vehicle 10.

[0094] When the service associated with the graphic object on which the touch press was made is implemented, the audio data, called third data, associated with the audio content(s) (telephone communication, voice instructions from the navigation system, audio content of the radio being listened to) of the service implemented are transmitted to a computer of the vehicle 10 (for example via the TCU and the on-board network of the vehicle 10) according to the wireless communication protocol implemented, for example Bluetooth®.

[0095] The audio content is then delivered to the passenger compartment via the speaker(s) of the vehicle 10, after possible amplification by the amplifier of the vehicle 10.

[0096] According to a particular embodiment, the vehicle 10 comprises control means configured to control parameters of the services implemented via the mobile application.

[0097] The control means comprise, for example, a steering wheel control module comprising control means for adjusting the volume of the sound and / or control means for selecting a radio station from among all the radio stations available via the broadcasting service and the web radio service. The volume adjustment makes it possible to adjust the volume via, for example, '+' keys or buttons and for any audio content received from the mobile communication device 101 and rendered via the speakers of the vehicle 10. The control means for selecting a radio station correspond, for example, to a dial or to any control member known to those skilled in the art. A user action performed on the dial triggers the sending of control instructions to the mobile application via the wireless communication protocol, for example Bluetooth®.Upon receipt of these control instructions, the display on the screen of the mobile communication device 101 is modified to display graphical content of the graphical user interface provided for controlling the radio stations. The steering wheel control module comprises, for example, a validation button for validating the radio selected via the dial; pressing the validation button triggers the sending of a control instruction to the mobile application via Bluetooth® to validate the selected radio station. The mobile application then controls the change of radio station.

[0098] According to an alternative embodiment, the control means are used to navigate in the graphical content of the graphical user interface described with regard to [Fig.2], for example to select the service to be implemented from among the services available and associated with the graphical objects 21 to 24.

[0099] The use of these control means allows the driver to keep his hands on the wheel while controlling one or more parameters such as the volume of the audio content associated with the services implemented via the mobile application and / or changing the radio station. Such control means make it possible to increase the safety of the vehicle and its passengers by providing a control / command input interface other than the touch interface of the mobile communication device 101.

[0100] According to another particular embodiment, the vehicle 10 comprises one or more microphones arranged in the passenger compartment of the vehicle 10, for example on the steering wheel and / or at the level of the interior rearview mirror. This or these microphones are used as an input interface and configured for the acquisition of voice commands pronounced by the driver of the vehicle 10 and / or a passenger. The data representative of these voice commands are transmitted to the mobile application via the wireless communication protocol (for example Bluetooth®) to control the mobile application and the services implemented via the mobile application. According to a variant, the voice commands are further used to control the volume of the sound of the audio content rendered via the vehicle's speakers 10. This or these microphones provide an alternative control / command input interface to the touch interface of the mobile communication device 101. Such a voice control interface also allows the driver to keep their hands on the wheel while controlling the mobile application.

[0101] [Fig. 3] schematically illustrates a device 3 configured for data communication between a mobile communication device and a vehicle, for example between the mobile communication device 101 and the vehicle 10, according to a particular and non-limiting exemplary embodiment of the present invention.
