Vehicle anti-theft matching method and system

Abstract

The invention provides a vehicle anti-theft matching method and system. According to the vehicle anti-theft matching method and system of the invention, the anti-theft states of PEPSs and ESCLs are judged; PEPSs and ESCLs which are subjected to anti-theft matching and have poor incoming parts are screened out, so that it is guaranteed that anti-theft matching equipment only carries out anti-theftmatching on blank PEPSs and ESCLs. The situation that repeated matching generates a plurality of anti-theft codes can be effectively prevented; the anti-theft matching errors of the PEPSs and ESCLs and key mismatching anti-theft codes are avoided. Besides, a detection result is output, so that an operator can visually see the reason why an anti-theft matching process is interrupted according to anoutput report, and therefore, the anti-theft repair efficiency and success rate of a vehicle are improved.

Description

technical field [0001] The invention relates to an offline detection of a diagnostic system in the field of automotive electronics, in particular to a method and system for vehicle anti-theft matching and key anti-theft matching. Background technique [0002] Along with popularizing of automobile in people's life, the phenomenon of losing a car also happens from time to time, therefore, anti-theft system becomes one of important configuration of automobile. At present, most of the electronic anti-theft systems used in automobiles are provided by parts suppliers with blank electronic steering column lock (Electronic Steering Column Lock, ESCL), keyless entry and start system (Passive Entry and Passive Start, PEPS), and then by the vehicle When the factory goes offline, the off-line equipment is used to uniformly match the anti-theft code and the key anti-theft matching, so as to realize the matching of the anti-theft system. The matching of the anti-theft system needs to wri...

AI Technical Summary

Problems solved by technology

In actual production, due to operator misoperation, ESCL, PEPS and key failure or repair, etc., several anti-theft matching processes are performed on the same ESCL, PEPS or key, resulting in different anti-theft keys being written into ESCL, PEPS or key. Code, ESCL, PEPS wrong match and key wrong anti-theft matching anti-theft code, so the repair rate is high, which reduces production efficiency

At the same time, since the matching process of ESCL and PEPS and the anti-theft matching of keys are one-time and irreversible, if the anti-theft matching fails, it will lead to waste of parts and increase the production cost of the factory
