Abstract

본 발명은 차량에 외부인의 침입에 의해 차량의 도난방지용 알림발생부가 자공하였을 때 이를 마이컴(ECU)이 감지하여 이상상태발생시 무선신호를 발생시켜 차량 소유자에게 신속하게 알릴 수 있는 원거리 차량도난 감지장치에 관한 것으로 차량에 외부인의 침입을 하면 도난감지부가 이를 감지하며 마이컴에 이상상태발생신호를 인가하고 상기 마이컴은 주파수발생부를 동작시켜 외부에 주파수신호를 발생시키며 상기 주파수발생부로부터 발생된 주파수신호를 리모트키이에서 수신하여 이상상태발생신호에 해당되면 즉시 경보음을 발생시켜 차량소유자가 알수 있게 하므로써 원거리에서도 차량도난을 신속히 감지하여 차량도난을 미연에 방지할 수 있는 효과가 있다.The present invention provides a remote vehicle theft detection device that can notify the owner of the vehicle quickly by generating a wireless signal when the microcomputer (ECU) detects when the alarm generation unit for preventing theft of the vehicle due to an outsider's intrusion into the vehicle itself occurs. When the intruder enters the vehicle, the theft detection unit detects this and applies an abnormal state occurrence signal to the microcomputer. The microcomputer operates the frequency generator to generate a frequency signal to the outside and remotely operates the frequency signal generated from the frequency generator. When received from the key, if an abnormal state signal occurs, an alarm sound is immediately generated so that the vehicle owner can know it, thereby quickly detecting a vehicle theft even at a long distance, thereby preventing the vehicle theft.
