桑塔纳驻车)(国外英文资料) Working principle and relieving method of parking anti-theft system At present, many car anti-theft devices are popular in the market, such as gearshift locks, steering wheel locks, electronic alarm and anti-theft devices, but these anti-theft devices are not insurance for those with high intelligence. With the further development and improvement of automotive electronic intelligence, a more secure and reliable anti-theft device - parking computer anti-theft system has been applied in many cars. If the vehicle with this anti-theft system is not equipped with the original key with a chip, even if the door is opened, the car can not be driven, and it can not be jumper and refit, so it is extremely safe. Shanghai Santana, Shanghai Passat, FAW Jetta, FAW Audi and other cars installed the device. 1 working principle of parking computer anti-theft system The parking computer anti-theft system consists of ignition keys, fire keys, coils, anti-theft computers, engines, computers, etc. (see below).
