- FIG. 4 illustrates a flowchart of the different steps of a data communication method in the system of FIG. 1, according to a particular embodiment of the present invention.
- a mobile communication device such as a smart telephone is coupled in communication with a vehicle via a wireless link or connection.
- a mobile application is advantageously installed on the mobile communication device and is configured to exchange data with a vehicle for the implementation of one or more services.
- a network extension is advantageously configured on the mobile communication device and implemented by the operating system of the mobile communication device. This network extension is configured on the one hand to establish a secure link or connection with the mobile application in the mobile communication device, for example by implementing a virtual private network local, and to establish communication with the vehicle via the wireless link or connection on the other hand.
- the exchange of data between the vehicle and the mobile application takes place via the network extension and the secure link.
- the network extension is executed directly by the operating system, the latter is not subject to the same management rules as a classic mobile application developed via an SDK (from the English “Software Development Kit” or “kit de software development” in French), i.e. the network extension runs permanently in the background and is not stopped by the operating system after a certain period of time has elapsed, unlike a classic mobile application.
- the network extension is then always available and able to receive data or requests from the vehicle, the network extension then being able to maintain the service(s) provided by the mobile application, even when the mobile application is stopped.
- Such a process thus makes it possible to provide a continuous service and to ensure permanent availability of the mobile application, greatly improving the quality of service.

- the vehicle 10 communicates with the mobile communication device 11 and exchanges data with the latter within the framework of one or more services executed by a or more mobile applications installed on the mobile communication device 11.
- a mobile application corresponds to application software developed specifically for the mobile communication device 11 using the SDK adapted to the operating system of the mobile communication device 11.
- the iOS SDK allows developers to develop a mobile application using the programming language(s) supported by iOS, i.e. for example the Swift and Objective-C languages.
- the Android SDK allows developers to develop a mobile application using the programming language(s) supported by Android, that is to say, for example, the Java or Kotlin.
- the mobile communication device 11 communicates for example with one or more computers of the on-board system of the vehicle 10 via one or more antennas connected to this or these computers, for example to a computer of the TCU type (from the English "Telematic Control Unit “or in French” telematics control unit >>), the TCU unit being connected to the other computers of the on-board system via a communication bus of a CAN-type wired network (from the English "Controller Area Network” or in French “Network of controllers >>), CAN FD (from English "Controller Area Network Flexible Data-Rate” or in French “Network of controllers with flexible data rate >>), FlexRay (standardized by standard ISO 17458) or Ethernet (standardized by standard ISO/IEC 802-3).

- BLE from English "Bluetooth Low Energy”
- the wireless connection or link between the mobile communication device 11 and the vehicle 10 is of the Wifi type (based on one of the standards of the IEEE 802.11 group), NFC (from the English “Near -Field Communication” or French CCP "Communication en Champ Proche >>) or Zigbee (based on the IEEE 802.15.4 standard).
- the mobile application installed on the mobile communication device 11 provides an ADML (Hands-Free Access and Startup) type service.
- ADML High-Free Access and Startup
- Such an application allows the wearer of the mobile communication device 11 to authenticate with the vehicle 10, allowing access to the vehicle 10 and to start it.
- the owner of the vehicle 10 does not need a physical key but simply his mobile communication device 11, for example a smart phone, with a mobile application providing an ADML service installed.
- the invention is not limited to a mobile application providing an ADML type service but extends to any type of mobile application and any type of service.
- FIG. 2 schematically illustrates an application architecture implemented in the mobile communication device 11 in communication with the vehicle 10, according to a particular and non-limiting embodiment of the present invention.
- the architecture of the mobile communication device 11 presented in FIG. 2 corresponds to a distributed application architecture and comprises two parts 21 and 22.
- a first part 21 notably comprises one (or more) network extension(s) 210 generated natively from the kernel of the operating system of the mobile communication device 11 .
- the network extension 210 corresponds to an extension of the Unix kernel from which the iOS operating system is derived.
- Such a network extension 210 is for example generated from an API (from the English “Application Programming Interface” or in French “Application Programming Interface”) conforming to the set of standards called POSIX and defined by the IEEE 1003 standard.
- the basic APIs described in POSIX relate to real-time services, lightweight processes, real-time extensions, security interface, file access over the network and inter-process communications over the network.
- a second part 22 comprises the mobile applications developed from the SDK adapted to the operating system of the mobile communication device 11, for example a mobile application 220 providing a service for the vehicle 10.
- the distributed application architecture of FIG. 2 thus comprises a mobile application 220 and its network extension 210, the mobile application 220 and the network extension 210 each corresponding to a software module implemented (for example executed) on the mobile communications 11 .
- the technical components in charge of communication with the vehicle 10 are advantageously taken care of and controlled by the network extension 210, the mobile application 220 storing for example the data and information allowing the provision of one or more services for the vehicle 10 or the owner of the vehicle 10 (for example configuration parameters, authentication data, environment data).
- the network extension 210 comprises the following components or modules, for example in the form of software modules:
- the module 211 configured to implement a secure connection between the network extension 210 and the mobile application 220.
- the module 211 takes for example the form of a server of a local virtual private network, called VPN network (of English "Virtual Private Network”), such a VPN server being configured to communicate with a VPN client implemented in the mobile application 220, the data communication between the VPN server and the VPN client being ensured via a tunnel encrypted or encrypted (inter-process communication IPC (English "Inter-Process Communication”)) forming a secure link 201 to ensure the security of the data exchanged.
- the module 211 is for example obtained or generated from the API called
- the module 212 corresponds for example to a server implementing a communication protocol in connected mode for the communication of data between the vehicle 10 and the network extension 210.
- the communication protocol corresponds for example to the so-called TCP protocol (from the English “Transmission Control Protocol” or in French “Transmission Control Protocol”).
- the module 212 acts as a bridge or a gateway between the module 211 on the one hand and a module 213 in charge of the transmission and reception of the signals carrying the data.
- the module 212 listens for example to the commands or requests sent by the mobile application 220 (and received by the module 211 via the secure connection (encrypted tunnel) between the mobile application 220 and the network extension 210 to format them and transmit them to the vehicle 10 via the module 213.
- the module 212 also listens for example to the commands or requests sent by the vehicle 10 according to the wireless link 200 and received by the module 213 to format them and transmit them to the application mobile 210 via module 211; and
- a module 213 configured to receive signals transmitted by the vehicle 10 and to transmit signals intended for the vehicle 10, these signals transporting data intended for the mobile application 220 or transmitted by the mobile application 220.
- the signals and the data they carry are advantageously communicated via a wireless link using BLE technology (from English “Bluetooth Low Energy” or in French “Bluetooth à basse consumption” or “Bluetooth à basse réelle", integrated into the Bluetooth standard from version 4.0).
- the mobile application 220 comprises the following components or modules, for example in the form of software modules:
- the module 212 takes for example the form of a VPN client configured to communicate with the VPN server 211 implemented in the network extension 210, the data communication between the VPN server and the VPN client being provided via an encrypted or encrypted tunnel forming the secure link 201 to ensure the security of the data exchanged;
- module 222 configured to manage the data of the mobile application 220, to implement the processes necessary to provide the service(s) of the mobile application.
- the module 222 transmits the data to the vehicle 10 via the module 221 then via the network extension 210 and receives the data transmitted by the vehicle 10 from the module 221 via the network extension 210.
- the mobile application 220 follows the classic life cycle of mobile applications developed via SDK, that is to say that the mobile application is put to sleep or stopped by the operating system of the mobile communication device after expiry of a determined period (for example 5 or 10 minutes) in the event of absence of use of the mobile application 220.
- the network extension 210 is installed within the operating system of the mobile communication device 11, for example iOS.
- Network extension is not subject to standard mobile application lifecycles.
- the 210 network extension remains active in the background and is never put to sleep or killed by the operating system.
- the network extension 210 remains attentive to certain events of the system 1 (network activity, Bluetooth events, resumption of activity by the user of the mobile communication device 11) given its design and its nature.
- the Network Extension 210 lifecycle is managed solely by the operating system of the mobile communication device. Once configured, the network extension corresponds to a system service in the background, for example a Unix daemon with the POSIX APIs of iOS.
- a daemon is a process not controlled by the user of the mobile communication device and which runs automatically in the background.
- Communication between the network extension 210 and the mobile application 220 passes through an encrypted tunnel 201 (inter-process communication or IPC) for synchronous commands, and through system notifications (Darwin notifications) with a militarized data sharing zone for asynchronous commands (for example for the reception of BLE signals from the vehicle 10 and/or the resumption of activity by the user of the device 11).
- IPC inter-process communication
- the installation of the module 221 (for example the VPN client) is proposed to the user, by example by displaying a message or a window in the 1'1 HM (Human-Machine Interface) of the mobile communication device 11 .
- the installation and configuration of the VPN are implemented automatically and transparently for the user, i.e. without requiring any action on the part of of the user.
- the network extension 210 is programmed to, when the user approaches the vehicle 10, for example wake up the mobile application 220 then sleeping, transmit commands or requests to the vehicle 10, retrieve the states issued, display notifications, update a widget, save data, etc.
- the awakening of the mobile application 220 is obtained indirectly, for example via the display or the rendering of a notification on the mobile communication device 11 intended for the user, the display or the rendering being controlled or commanded by network extension.
- the user is alerted that he must activate the mobile application 220.
- the ADML service is available as soon as the installation and configuration of the VPN solution have been implemented, whether the mobile application 220 is launched (executed) or not.
- the ADML service is automatically reconstituted by the network extension, with the context or user profile, and the ADML service automatically connects with the vehicle 10 or any vehicle within range of the radio link of the device. mobile communication 11 (that is to say the module 213).
- the network extension 210 receives, via the BLE connection, an authentication request sent by the vehicle 10 to the mobile application 220. If the mobile application 220 is stopped (for example following a absence of use by the user of the mobile communication device 11 for a duration greater than a threshold (for example 10 minutes)), the network extension 210 saves the data associated with the request in an accessible data sharing zone to the mobile application 220 and/or to an interactive thumbnail (“widget”). Upon receipt of the request, the network extension 210 generates, for example, a notification intended for the user of the mobile communication device so that the latter activates the mobile application 220 or responds to the request sent by the vehicle. According to a variant, the interactive vignette transmits the necessary command(s) to the vehicle 10 instead of the mobile application 220.
- a threshold for example 10 minutes
- the network extension is automatically uninstalled as well.
