Automobile locking system based on automobile-mounted terminal and method of automobile locking system

Abstract

The invention provides an automobile locking system based on an automobile-mounted terminal and a method of the automobile locking system. The automobile locking system based on the automobile-mountedterminal comprises the automobile-mounted terminal located in an automobile, and the automobile-mounted terminal is connected with a T15 switch in the automobile; and the automobile-mounted terminalis further connected with an engine ECU of the automobile through a CAN bus. The automobile comprises an ignition switch, the ignition switch comprises an ACC gear, an ON gear (T15) and a START gear (T50). The automobile-mounted terminal comprises a detection module and an automobile locking module; the detection module is used for judging the type of the engine by detecting identification messages; and the automobile locking module is used for adopting corresponding automobile locking logic according to the judged type of the engine to realize the automobile locking function. The defects thatin the prior art, automobile-mounted terminal functions are too single, the compatibility is poor, using of an existing automobile-mounted terminal is restrained, and detection cannot be carried outif the automobile-mounted terminal does not receive the identification messages are effectively overcome.

Description

technical field [0001] The invention relates to the technical field of car locking, in particular to a car locking system and method based on a vehicle-mounted terminal. Background technique [0002] The switch of the ignition system (usually using a key), that is, the ignition switch, can freely open or close the main circuit of the ignition coil, and is also suitable for other electrical circuits. The ignition switch is commonly known as the master switch, the master switch or the master key. It is the master gate that controls the entire vehicle circuit system. [0003] The car lock function needs to be realized by the cooperation of the ignition switch, the vehicle terminal and the engine electronic control unit ECU. The vehicle-mounted terminal and the engine ECU communicate and interact through the CAN bus, and the engine ECU executes the lock operation after receiving the lock command sent by the vehicle-mounted terminal. If the vehicle is in the driving state, the ...

Problems solved by technology

[0006] In order to solve the above problems, the present invention provides a vehicle-mounted terminal-based car locking system and its method, which effectively avoids the lock-up logic of the car engine in which the vehicle-mounted terminal can only handle the vehicle engine in the prior art, making it impossible to realize For this type of car engine, the car locking function and the vehicle terminal function are too single and the compatibility is poor, which restricts the use of the existing vehicle terminal. If the vehicle terminal does not receive the identification message, it cannot detect the defect.
