Embodiment Construction

[0036] see figure 1 , is an embodiment of the vehicle anti-theft matching method of the present invention.

[0037] The anti-theft matching method of this embodiment includes the following steps:

[0038] Step S101: read the anti-theft status of PEPS and ESCL;

[0039] Step S102: judging whether the PEPS and ESCL anti-theft states are both unwritten, if both are unwritten, then perform step S103, otherwise end the anti-theft matching process;

[0040] Step S103: write anti-theft codes to the PEPS and ESCL;

[0041] Step S104: Write the anti-theft code into the key.

[0042] In this embodiment, the anti-theft state of PEPS and ESCL is judged to ensure that the anti-theft matching device only writes the anti-theft code to blank PEPS and ESCL, which can effectively prevent the anti-theft matching error of PEPS and ESCL caused by repeated matching to generate multiple anti-theft codes and If the key is incorrectly written into the anti-theft code, it can also avoid the vehicle...

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...
