Anti-theft device for vehicle

Abstract

The invention provides a vehicle anti-theft device that integrates an electronic control unit for vehicle anti-theft and an electronic control unit for ignition time control and is installed in a shell, with small size, low cost and strong anti-theft capability. The vehicle anti-theft device has: a stopper 2, an anti-theft electronic control unit 3, an ignition 4, a sensor 6, a remote control unit 7 and an alarm unit 8.

Description

technical field [0001] The invention relates to a vehicle anti-theft device, in particular to a vehicle anti-theft electronic control unit and an electronic control unit for controlling the ignition time of the igniter are integrated in one casing and has a small and low-cost vehicle anti-theft device with strong anti-theft capability. technical background [0002] Existing anti-theft devices for vehicles, such as those shown in Japanese Patent Laid-Open No. 6-286583, use keys to switch on or off the power line from the power supply to the igniter, and use sensors to detect the switch of the ignition switch that controls the running of the vehicle. Abnormal conditions such as mechanism damage and disassembly, at least control the function of one part of the igniter, so that the igniter is in a non-working state, so that the engine cannot be started. [0003] Another known vehicle anti-theft device utilizes remote control (remote controller) operation to control various anti-...

Problems solved by technology

[0006] Furthermore, in the vehicle anti-theft device that controls various anti-theft functions through the existing remote control operation, the electronic circuit of the receiving part for the remote control operation provided on the vehicle side is not integrated with the electronic control unit of the vehicle anti-theft device. Therefore, the connection line connecting the receiving part and the electronic control unit of the vehicle anti-theft device exists independently. If the connection line bears a physical load, it may cause short circuit and other phenomena, resulting in malfunction.

[0007] In addition, in the existing vehicle anti-theft device that adopts the bolted wire rope, the electronic control unit that detects the cut-off state of the bolted wire rope for anti-theft is not integrated with the electronic control unit of the vehicle anti-theft device. The connecting line connecting the electronic control unit of the wire rope and the electronic control unit of the vehicle anti-theft device exists independently. If the connecting line bears a physical load, it may cause short circuit and other phenomena, resulting in malfunction
