차량 충돌시 엔진 오프 장치Engine Off Device in Vehicle Crash

본 고안은 차량 충돌시 엔진 오프 장치에 관한 것이며, 보다 상세히는 기존의 에어백 시스템을 이용하여 차량 충돌시 엔진의 시동을 자동적으로 오프시키는 차량 충돌시 엔진 오프 장치에 관한 것이다.The present invention relates to an engine off device in a vehicle crash, and more particularly, to an engine off device in a vehicle crash that automatically turns off the engine in a vehicle crash using an existing airbag system.

종래의 경우를 도 1를 참조하여 설명하기로 한다.A conventional case will be described with reference to FIG. 1.

일반적인 에어백 시스템은 전원 공급부(1)와, 상기 전원 공급부의 전원 공급을 제어하기 위한 안전 센서(2)와, 차량의 가속도를 측정하기 위한 가속도 센서(7)와, 에어백 시스템의 전 회로를 제어하기 위한 중앙처리장치(6)와, 상기 중앙처리장치의 명령에 따라 작동되는 제 1 전기 스위치(3) 및 제 2 전기 스위치(4)와, 상기 스위치(3, 4)와 접속되며 에어백 모듈을 작동시키는 인플레이터(5)로 구성된다.A general airbag system includes a power supply unit 1, a safety sensor 2 for controlling the power supply of the power supply unit, an acceleration sensor 7 for measuring the acceleration of the vehicle, and an entire circuit of the airbag system.

따라서, 본 고안은 상술한 종래의 문제점을 극복하기 위한 것으로서, 본 고안의 목적은 에어백이 전개되도록 중앙처리장치가 명령을 내리면 엔진 시동이 꺼지도록하는 차량 충돌시 엔진 오프 장치를 제공하는데 있다.Accordingly, the present invention is to overcome the above-mentioned conventional problems, and an object of the present invention is to provide an engine off device in a vehicle collision such that the engine is turned off when the central processing unit commands the airbag to be deployed.

상기 본 고안의 목적을 달성하기 위한 차량 충돌시 엔진 오프 장치의 일예로서, 전원 공급부와, 상기 전원 공급부의 전원 공급을 제어하기 위한 안전 센서와, 차량의 가속도를 측정하기 위한 가속도 센서와, 에어백 시스템의 전 회로를 제어하기 위한 중앙처리장치와, 상기 중앙처리장치의 명령에 따라 작동되는 제 1 전기 스위치 및 제 2 전기 스위치와, 상기 스위치와 접속되며 에어백 모듈을 작동시키는 인플레이터로 구성되는 에어백 시스템에 있어서,As an example of an engine off device in a vehicle collision to achieve the object of the present invention, a power supply, a safety sensor for controlling the power supply of the power supply, an acceleration sensor for measuring the acceleration of the vehicle, airbag system An airbag system comprising a central processing unit for controlling all circuits of the first circuit, a first electrical switch and a second electrical switch operated according to a command of the central processing unit, and an inflator connected to the switch and operating an airbag module. In

상기 인플레이터와 병렬로 엔진 구동 장치를 오프시키는 엔진 오프 장치를 더 포함하는 것을 특징으로 한다.And an engine off device for turning off the engine driving device in parallel with the inflator.

이러한 구성에 의해, 충돌시 에어백의 전개와 동시에 엔진 시동이 꺼지게 된다.With this arrangement, the engine starts to be turned off simultaneously with the deployment of the airbag in the event of a collision.
