Diagnosis system suitable for different vehicles

Abstract

The present invention provides a diagnosis system suitable for different vehicles, wherein the vehicle comprises vehicle model information and a plurality of control systems corresponding to the vehicle model information. The diagnosis system comprises a diagnosis device; the diagnosis device is used for sending a call instruction to a vehicle to be tested, calling the vehicle model information of the vehicle according to the call instruction and determining the plurality of control systems corresponding to the vehicle model information according to the called vehicle model information; and the control systems are connected with the gateway of the vehicle and are used for transmitting the state information and communication information of the vehicle to the diagnosis device so that the diagnosis device realizes the fault detection of the vehicle. With the diagnosis system of the invention adopted, the problem of need for a large amount of money to realize diagnosis software upgrade after the configurations of new vehicle models on the market or sold vehicles models are modified can be solved, the maintenance period of after-sales diagnosis software can be shortened, and the stability of the after-sales diagnosis software can be ensured.

Description

technical field [0001] The invention relates to the technical field of vehicle diagnosis, in particular to a diagnosis system applicable to different vehicles. Background technique [0002] As a professional tool for vehicle detection, the vehicle diagnostic device can detect vehicle performance in real time and is a necessary tool for detecting vehicle faults. At present, in the development process of the diagnostic device, the diagnostic protocols adopted by different models of the same automobile factory are different, and each new car needs to develop supporting diagnostic software when it is put on the market. For the same type of controllers from different suppliers, they often use their own diagnostic protocols. Therefore, when diagnosing the same type of controllers provided by different suppliers, it is often necessary to upgrade the software of the diagnostic device. In the case of development by track-two suppliers, OEMs often require them to develop in accordanc...
