A method and apparatus for performing diagnostics of a vehicle

Abstract

The invention discloses a method and a device for performing vehicle diagnosis, comprising the following steps: obtaining a vehicle identification number from a target vehicle through a mobile diagnosis tool; searching and matching the vehicle identification number from a diagnosis database of the mobile diagnosis tool according to the vehicle identification number historical data associated with the vehicle identification number, wherein the historical data includes a record of the type of diagnostic tool compatible with the vehicle data bus system; based on the lookup, it is determined whether the type of mobile diagnostic tool is compatible with the data bus system of the target vehicle If the judgment result is yes, a connection is established between the mobile diagnostic tool and the target vehicle through the vehicle data connector; after the connection is established between the mobile diagnostic tool and the target vehicle, at least one of the following steps is performed: Display interface operation; the invention can help the same type of problems in the same type of vehicles to be solved quickly, thereby effectively reducing maintenance costs and maintenance man-hours, and improving vehicle maintenance efficiency.

Description

technical field

[0001] The invention relates to the technical field of vehicle diagnosis, in particular to a method and device for performing vehicle diagnosis. Background technique

[0002] At present, automobiles have become the most familiar and common means of transportation for people, and they play a very important role in people's lives. Although automobiles have different qualities and various forms, various faults will inevitably occur during their use, which need to be eliminated or repaired in time. With the advancement of technology, the degree of automation of automobiles is getting higher and higher, the performance is superior, and the operation is more convenient and flexible. On the other hand, higher requirements are put forward for automobile maintenance and testing. Traditional manual monitoring and maintenance methods can no longer Meet the maintenance needs of new cars.
