Vehicle diagnosis method, device and equipment

Abstract

The invention provides vehicle diagnosis method, device and equipment and relates to the technical field of vehicle diagnosis. The vehicle diagnosis method includes: acquiring vehicle identification code acquired by a vehicle electronic control unit through a vehicle information processing unit; decoding if the vehicle identification code is the same with a preset vehicle identification code; reading information of vehicle parts after the decoding is succeed; according to the information of the vehicle parts, performing fault diagnosis on the vehicle. Information of the corresponding vehicle can be found by information matching between the vehicle identification code and the preset vehicle identification code, and vehicle diagnosis is forbidden when information of the vehicle is changed; the decoding process can prevent the vehicle from being controlled optionally, and vehicle diagnosis is forbidden if the decoding is failed; information of the vehicle parts is read after the decodingis succeed, failure diagnosis is performed to the vehicle according to the information of the vehicle parts, and thus vehicle failure diagnosis can be completed safely.

Description

technical field [0001] The invention relates to the technical field of vehicle diagnosis, in particular to a vehicle diagnosis method, device and equipment. Background technique [0002] At present, the automobile diagnostic instrument is a professional instrument for automobile detection, which can detect the performance of the vehicle in real time and judge the fault of the vehicle. The general diagnostic instrument uses a hand-held portable diagnostic instrument and a PC diagnostic instrument. However, if the traditional diagnostic instrument In the case of reset operation or tampering with the vehicle identification code, it is easy to cause the key information of the vehicle to be cracked and then control the vehicle, causing potential safety hazards for the entire vehicle. [0003] Therefore, there is an urgent need for a vehicle diagnosis method, device and equipment, which can solve the safety problem that the key information of the vehicle is easily cracked, which m...
