The present invention relates to a sudden acceleration prevention device and a sudden acceleration prevention method. The present invention discloses a sudden acceleration prevention device comprising: an accelerator detection sensor for providing an acceleration output value, which is an output value depending on the degree of a driver stepping on an accelerator; a control part for determining whether sudden acceleration occurs using an engine rpm value (motor current value applied to a motor in the case of an electric vehicle) and the acceleration output value input from the accelerator detection sensor, and generating a second power disconnection signal and an engine ECU data deletion signal when sudden acceleration is determined to occur; and a second power switch for disconnecting power supplied to a fuel pump for one hour according to the second power disconnection signal, and then supplying power again. The sudden acceleration prevention device and the sudden acceleration prevention method according to the present invention may be realized using fewer circuit components, and may be operated independently of an in-vehicle communication network, thereby stably preventing the sudden acceleration of a 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.
