Vehicle remote fault diagnosis method and device based on V2X

Abstract

The invention discloses a vehicle remote fault diagnosis method and device based on V2X. The method comprises the steps of reporting a message through V2X communication according to a preset time period, and enabling the message to comprise an information message, a power-on/power-off message and a fault message of a target vehicle, detecting whether a message is received, when the message is received and the fault message is not null, reporting the message to a remote diagnosis platform, so that the remote diagnosis platform can analyze a vehicle fault reason according to the received message, when the message is not received, the power-off message of the target vehicle is not received in the message of the last period, and the target vehicle is in the V2X communication range, deducing that the power supply system has a fault, and reporting the information message of the target vehicle and the fault message of the power supply system to a remote diagnosis platform. Therefore, the remote diagnosis platform can analyze the cause of the vehicle fault according to the received message. Labor cost and detection cost are saved, and reliable data guarantee is provided.

Description

technical field [0001] The invention relates to the technical field of vehicle fault diagnosis, in particular to a V2X-based vehicle remote fault diagnosis method and device. Background technique [0002] The number and usage of cars today is increasing year by year. In the daily use of automobiles, vehicle failures will inevitably occur, such as power domain failures, chassis domain failures, body domain failures, power supply system failures, network failures (that is, vehicles do not have the ability to access the Internet), etc., especially It is difficult for the owner to discover the hidden faults in the vehicle itself. Only when the faults are revealed and affect the normal use of the vehicle, the driver will find out. Obviously, there are potential safety hazards. [0003] In order to solve vehicle failures in a timely and effective manner to ensure safe driving, two methods are generally adopted in the prior art: the first one is to drive the vehicle to a 4S shop, ...

Problems solved by technology

[0006] Obviously, this method can remotely diagnose vehicle faults. Compared with the driver who goes to the maintenance point for repairs after discovering the fault, it not only improves safety, but also reduces maintenance costs and time costs, thereby improving the after-sales satisfaction of car owners. , However, the failure report of this method depends on the networking capability of the on-board T-Box. If the vehicle failure is a failure of the power supply system, the T-Box cannot be powered normally, or the vehicle network failure causes the T-Box to be unable to connect to the Internet. The remote diagnosis platform will not be able to clearly obtain the cause of the failure
