Control device and method for achieving theft prevention of vehicle through gear device

Abstract

The invention discloses a control device and method for achieving theft prevention of a vehicle through a gear device. According to the control device and method, a vehicle can be started in a remote mode, and a vehicle-mounted air conditioner is turned on or one-key starting of the vehicle is achieved before the vehicle runs; an electric motor vehicle and a hydrogen motor vehicle can be electrified in a remote mode, and in addition, the vehicle-mounted air conditioner is turned on before the vehicle runs; the vehicle-mounted air conditioner is turned on in a remote mode when the electric motor vehicle is charged by being conducted with an external power supply. Electric power of a vehicle-mounted battery is saved, and meanwhile, the theft prevention function of the vehicle is achieved through necessary gear device operation before the vehicle runs. According to the control device and method for achieving theft prevention of the vehicle through the gear device, before the vehicle runs, the vehicle is switched to an advancing gear or a retrogressing gear from a parking gear through the gear device operation, a theft prevention control unit in the vehicle judges the validity of a portable electronic key read by a reading coil, the gear control unit controls a gear executing unit to execute a gear changing information order sent by a gear sensor or not to execute the gear changing information order according to the judgment result of the theft prevention control unit, and therefore theft prevention of the vehicle is achieved.

Description

technical field

[0001] The invention relates to a vehicle anti-theft system, in particular to a control device and method for realizing vehicle anti-theft by operating a gear shifter, and belongs to the field of automobile anti-theft. Background technique

[0002] At present, in the field of car anti-theft, in order to realize car anti-theft, when the portable electronic key of the car is ignited, the anti-theft control unit judges the legitimacy of reading the portable electronic key through the reading coil. After the verification is passed, the car engine can be started normally. Lock the starting circuit of the car engine, the oil circuit, etc.; and when the shifter shifts from the parking gear to other positions, the portable electronic key is verified. After the verification is passed, the engine start permission signal is output, and the vehicle engine Allow to start. These methods all have the effect of not being able to remotely start the car and turn on the car ai...
