The invention provides an automobile anti-theft device. The device comprises a relay, a reed switch and an induction magnet. The relay is provided with a plurality of normally-open contacts, and the normally-open contacts of the relay are arranged on a circuit between an electromagnetic coil of a vehicle fuel injector and an ECU of an engine. The reed switch comprises a common reed, a normally open reed and a normally closed reed, the reed switch is connected in series with the relay through a normally open contact, and the reed switch and the relay which are connected in series are respectively connected with a power supply and a B + end of the engine ECU; and the induction magnets control the conduction of reed contacts in the corresponding reed pipes. According to the automobile anti-theft device, the normally open contact of the relay is connected to a circuit between the ECU and the electromagnetic coil of the oil sprayer in series, if the normally open contact of the relay is not closed, an oil supply signal of the ECU is interrupted, the oil sprayer does not spray oil, and an automobile cannot be started. Only when the circuit between the reed pipe and the relay is communicated and the normally open contact of the relay is controlled to be closed, an ECU oil feeding signal can be communicated with the oil sprayer, and the engine can operate.
本发明给出了一种汽车防盗装置;包括继电器、干簧管和感应磁铁;继电器设有若干常开触点,继电器的常开触点设置在车辆喷油器的电磁线圈与发动机的ECU的之间电路上;所述干簧管包括公共簧片、常开簧片和常闭簧片,所述干簧管通过常开触点与继电器串联,串联后的干簧管和继电器分别与电源和发动机ECU的B+端连接;所述感应磁铁控制对应干簧管内部簧片触点的导通。本汽车防盗装置就是利用继电器的常开触点串联到ECU至喷油器的电磁线圈之间的电路上,继电器的常开触点不闭合,则ECU给油的信号中断,喷油器不喷油,车也不能启动。只有连通干簧管与继电器之间的电路,控制继电器的常开触点闭合,ECU给油的信号才能连通才能喷油器,发动机才能运转。
