Vehicle diagnostic system and vehicle diagnostic method

Abstract

The invention provides a vehicle diagnostic system and a vehicle diagnostic method. The vehicle diagnostic system comprises a diagnostic terminal, a vehicle communication switching device and an in-vehicle diagnostic device, wherein the diagnostic terminal is used for sending a signaling to the in-vehicle diagnostic device through the vehicle communication switching device and receiving and processing data from the in-vehicle diagnostic device; the vehicle communication switching device is used for analyzing the signaling from the diagnostic terminal and transmitting the analyzed signaling to the in-vehicle diagnostic device by virtue of a preset format; and the in-vehicle diagnostic device is used for transmitting the monitored data to the diagnostic terminal through the vehicle communication switching device according to the received signaling. The vehicle diagnostic system and the vehicle diagnostic method which are disclosed by the invention are suitable for being used by individual users and can adapt to various vehicle bus communication protocols.

Description

technical field [0001] The present invention relates to a vehicle diagnosis system and method, more particularly, to a vehicle diagnosis system and method adapted to communication protocols. Background technique [0002] At present, with the increasing popularity of automobiles, the maintenance and maintenance of vehicles has become more and more important. However, since the vast majority of vehicle users are not professionals in the automotive technical field, it is difficult to find faults in the vehicle in time. Therefore, the portable vehicle diagnostic tool is helpful for vehicle users to diagnose and maintain vehicle faults. [0003] Therefore, with the popularization of on-board diagnostic systems, it has become more and more common to perform fault diagnosis of vehicles by reading data in electronic control units (ECUs) of vehicles. [0004] The diagnostic terminal generally communicates with the interior of the vehicle through the vehicle bus to complete tasks su...

AI Technical Summary

Problems solved by technology

[0005] However, the existing vehicle diagnosis systems and methods usually only support limited communication protocols, so they cannot be applied to all car models. In addition, the existing technical solutions are cumbersome to operate, so they are not suitable for ordinary individual users (such as individual car owners)
