The present invention relates to a sudden acceleration prevention device and a sudden acceleration prevention method. The sudden acceleration prevention device comprises: an accelerator detection sensor which provides an acceleration output value according to a degree of stepping the accelerator by a driver; a control unit which determines whether there is sudden acceleration by using an engine rpm value (motor current value applied to a motor for an electric vehicle) and the acceleration output value input from the accelerator detection sensor, and generates a second power disconnection signal and an engine ECU data deletion signal when it is determined that there is sudden acceleration; and a second power switch which disconnects power supplied from a fuel pump for one hour according to the second power disconnection signal, and then supplies power again. The sudden acceleration prevention device and a sudden acceleration prevention method according to the present invention can be implemented with fewer circuit components, operated independently from an in-vehicle communication network, and thus stably prevent sudden acceleration of the vehicle.

    본 발명은 급발진 방지 장치 및 급발진 방지 방법에 관한 것이다. 본 발명에서는 운전자가 엑셀레이터를 밟는 정도에 따른 출력값인 엑셀출력값을 제공하는 엑셀레이터 감지센서와, 엔진 rpm 값(전기 자동차의 경우는 모터에 인가되는 모터 전류값) 및 상기 엑셀레이터 감지센서로부터 입력되는 엑셀출력값을 이용하여 급발진 여부를 판별하고, 급발진이라 판별될 경우 제2전원차단신호 및 엔진 ECU 데이터삭제신호를 생성하는 제어부와, 제2전원차단신호에 따라 연료펌프에 공급되는 전원을 제1시간 동안 차단한 후 다시 공급하는 제2전원스위치를 포함하는 것을 특징으로 하는 급발진 방지 장치가 개시된다. 본 발명에 따른 급발진 방지 장치 및 급발진 방지 방법에 의하면 적은 회로부품으로 구현할 수 있으며 차량 내부 통신망과 독립적으로 동작되어 안정적으로 차량의 급발진을 방지할 수 있게 되었다.
