Abstract

The invention discloses a remote fault diagnosis method based on bus automatic switching and free configuration protocol. The method comprises: calling a corresponding middleware according to the CANbus mode of the current diagnosis by an application terminal; calling an acquisition interface of vehicle basic information by the middleware to obtain the corresponding instruction from a configuration library, and sending the instruction to a diagnostic box through a TCP communication manner; transmitting the instruction to an ECU by the diagnostic box, so that the ECU returns a CANECU data packet and instruction execution status to the diagnostic box after performing the corresponding diagnostic processing according to the instruction; transmitting the CANECU data packet and the instructionexecution status to the middleware by the diagnostic box; parsing the CANECU data packet through the configuration parsing rule of the configuration library by the middleware, and returning the parsing data and the instruction execution status to the application terminal, therefore, the application terminal displays the parsing data and the instruction execution status. The method can realize remote fault diagnosis for various vehicle models by switching buses.

Description

technical field [0001] The invention relates to the technical field of vehicle maintenance, in particular to a remote fault diagnosis method based on bus automatic switching and free configuration protocols. Background technique [0002] Existing remote diagnosis technologies generally require a clear understanding of the communication protocol with the underlying hardware in order to communicate with the underlying hardware and obtain relevant information, such as collecting vehicle fault codes, you need to know the specific protocols of the relevant models, and these are not disclosed by the manufacturers , involving the manufacturer's technical secrets. Therefore, how to separate the protocol from the software, which not only realizes remote fault diagnosis, but also meets the manufacturer's confidentiality requirements for its own protocol, has become the focus of current research. Contents of the invention [0003] The embodiment of the present invention proposes a r...
