The present invention relates to a method for preventing sudden acceleration due to an erroneous operation of a vehicle pedal, which, when the driver has fully (100%) stepped on the acceleration pedal in mistake for the brake pedal in an emergency, may automatically reduce the engine RPM to the idle RPM, thereby preventing accidents caused by sudden acceleration. To this end, the present method may: set a sudden acceleration prevention function according to the control of a sudden acceleration prevention switch; when the driver presses the acceleration pedal, check whether the state is in full acceleration; when the state is in full acceleration, control an engine control unit (ECU) to control an engine by automatically entering in a full acceleration kick-down mode and control the transmission of an acceleration prevention guiding voice; and, after the engine control unit is controlled, check whether the engine RPM is in the idle state, so as to reset the control of the engine control unit when the engine RPM is in the idle state, and, when the engine RPM is not in the idle state, operate a push rod motor to forcibly push the acceleration pedal in the direction opposite to the direction in which the same is being pushed, thereby preventing sudden acceleration due to the erroneous operation of the pedal.

    운전자가 긴급한 상황에서 가속 페달을 브레이크 페달로 혼동하여 풀 악셀(100%)로 밟았을 경우 엔진 RPM을 공회전 RPM으로 자동으로 떨어트려 급가속으로 인한 사고를 방지할 수 있도록 한 자동차의 페달 오조작에 따른 급가속 방지방법에 관한 것으로서, 급가속 방지 스위치의 조작에 따라 급가속 방지 기능을 설정하고, 운전자가 가속 페달을 누르면 풀(full) 악셀 상태인지를 확인하여, 풀 악셀 상태이면 자동으로 풀 악셀 킥 다운 모드로 진입을 하여 엔진을 제어하는 엔진 컨트롤 유닛(ECU)을 제어하고, 가속 방지 안내 음성의 송출을 제어하며, 엔진 컨트롤 유닛 제어 후, 엔진 회전수가 공회전 상태인지를 확인하여 엔진 회전수가 공회전 상태이면 엔진 컨트롤 유닛의 제어를 리셋하고, 엔진 회전수가 공회전 상태가 아니면 푸시로드 모터를 작동시켜 강제로 가속페달을 눌러지는 반대 방향으로 밀어내어, 페달 오조작에 따른 급가속을 방지한다.
