Embodiment Construction

[0021] An intelligent car anti-theft system based on a vehicle communication system according to an exemplary embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] figure 1 A structural diagram of a communication network of an intelligent car anti-theft device according to an embodiment of the present invention is shown. The window anti-pinch module collects the window position information and the window anti-pinch information, and communicates with the BCM through the LIN bus. BCM collects door lock status information, door opening status information, and remote control signals, and communicates with the vehicle communication system through CAN buses CANL and CANH. The vehicle communication system will notify the user in real time of the information received through the CAN bus.

Abstract

The invention provides an intelligent anti-theft device of an automobile based on an in-vehicle communication system, comprising a body control module (BCM) and an in-vehicle communication system. The BCM acquires the vehicle window state and the anti-clamping information sent by a vehicle window anti-clamping module via an LIN (Local Interconnect Network) bus and receives remote control information at the same time to carry out anti-theft setting on the vehicle; the anti-theft setting information and the window and door information are sent to the in-vehicle communication system by a controller area network (CAN) bus. The in-vehicle communication system acquires the concerned automobile parameters of users, including window and door information, fuel amount and tire pressure via the CAN bus; the whole vehicle is positioned by an integrated global positioning system (GPS) functional module; the vehicle positioning information and the acquired information are informed to the users in time by an integrated global system for mobile communication (GSM) functional module, so that the intelligent anti-theft effect of the vehicle is realized.

Description

technical field [0001] The invention relates to an automobile anti-theft device, in particular to an automobile intelligent anti-theft device based on a vehicle communication system. Background technique [0002] The current car anti-theft mainly uses short-distance radio technology. The vehicle is equipped with a body control module (BCM) or a similar module, which integrates a remote control processing circuit, which mainly receives the signal transmitted by the remote control, and at the same time locks the entire vehicle and closes the windows. Action, this kind of anti-theft system belongs to the open-loop control system, the remote control sends signals, and the BCM performs actions according to the remote control instructions. Since the remote control distance is only valid within the range of 11 meters, beyond this distance, the user cannot know the current status information of the vehicle. Contents of the invention [0003] The purpose of the present inventio...
