Vehicle diagnostic system and method

Abstract

The invention relates to a vehicle diagnosis system and method. The method comprises the steps of: obtaining diagnosis data from a vehicle by using a first communication protocol formed by segmentingdifferent diagnosis services according to vehicle diagnosis protocols of manufacturers or brands, and sending the diagnosis data to a mobile terminal; converting the target diagnosis data into data ina network protocol format used by the server according to a second communication protocol formed by dividing different diagnosis services by utilizing each network protocol, and sending the data to the server, wherein the server compares the data in the network protocol format with corresponding diagnosis standard data in a database to obtain a diagnosis result and sends the diagnosis result to the mobile terminal for display. Compared with the prior art, mutual communication between the mobile terminal, the server and the OBD equipment and vehicles of different manufacturers or brands is achieved through the first communication protocol and the second communication protocol corresponding to the diagnosis service, and the vehicle maintenance efficiency is improved.

Problems solved by technology

Professional computers generally integrate many advanced functions, but they do not require many advanced functions for routine maintenance and diagnosis, and also raise the threshold for using computer software

The manufacturer will upgrade the vehicle system from time to time. After the upgrade, the old professional software may not be supported. It is necessary to upgrade the diagnostic database or software, or even replace the professional computer, etc.

To provide maintenance and diagnosis related services for vehicles of different brands, it is necessary to purchase professional computers of different brands, and the maintenance personnel need to receive training on the use of professional computers of different brands, which undoubtedly brings great inconvenience to the maintenance personnel
