Embodiment Construction

[0046] In order to compensate for the limitations imposed by the physical connection, here it is proposed that the diagnostic tool communicate with the motor vehicle without going through the interface VCI. For this purpose, a virtual interface VVCI (VirtualVCI) is implemented.

[0047] refer to figure 1 In an embodiment, the user terminal 1 includes a motor vehicle diagnostic tool 2, such as the software DiagBox.

[0048] Here, the user terminal 1 denotes all user devices that share one or more data display components associated with the loaded motor vehicle diagnostic tool 2 and comprising at least one wireless communication module 3 (eg Compatible Wifi network, Bluetooth network, or cellular network card), said at least one wireless communication module can exchange data with a remote motor vehicle 5 through at least one (fixed or mobile) wireless communication network 4 . As an example, the user terminal 1 can be a fixed or portable computer, smart phone or tablet comput...

Abstract

The invention relates to a motor vehicle (5) diagnosis system provided with a first wireless communication module (6), said diagnosis system comprising: a diagnosis tool (2) configured to send a diagnosis request to the motor vehicle (5); a second wireless communication module (3) configured to transmit the diagnosis request sent by the diagnosis tool (2) to the first module (6); and a software module (8) acting as an interface between the diagnosis tool (2) and the second wireless communication module (3), said software module (8) being configured to: intercept the diagnosis request sent by the diagnosis tool (2), encapsulate the intercepted diagnosis request in a frame, and transfer the frame encapsulating the diagnosis request to the second wireless communication module (3).

Description

technical field [0001] The invention relates to the field of remote diagnostics of motor vehicles, and more precisely to the virtualization of the Vehicle Communication Interface or VCI (Vehicle Communication Interface). Background technique [0002] Current vehicles include on-board diagnostics or OBD (On-BoardDiagnostics), which are implemented, for example, by an on-board computer and provide information related to the status of different on-board electronic systems (eg: engine, braking system, cabin) . [0003] This information can be used for diagnostic purposes by vehicle mechanics or motor vehicle manufacturers, for example during vehicle maintenance or repair. [0004] In order to obtain this information, the current solution consists in connecting a physical communication card with the standard vehicle communication interface VCI between the vehicle and a diagnostic tool provided by the manufacturer, such as Peugeot Citroën's software DiagBox. [0005] For example...
