Zusammenfassung:	According to an embodiment of the present invention, a device for preventing a sudden unexpected acceleration of a vehicle comprises: a drive information collection part; a vehicle characteristic storage part; a control part; and a switching part. The drive information collection part includes a brake signal of the vehicle, a speed of the vehicle, revolutions per minute of an engine, revolutions per minute of a turbine and an open degree of an acceleration pedal and collects information on at least one of momentary fuel consumption, flow rate of inducted air, temperature of cooling air, temperature of engine oil, temperature of transmission oil, slope of a road and air pressure. The vehicle characteristic storage part includes the weight of the vehicle, a torque converter characteristic curved line and a drive resistance of the vehicle and stores data on at least one of a gear ratio, dynamic radius, frictional force of each gear step, engine moving system-inertia and power train moving system-inertia. The control part estimates the fuel consumption of each element of the vehicle based on the information and data, includes the fuel consumption with respect to transmission slip loss work and acceleration resistance loss work of the estimated fuel consumption, and determines whether the vehicle performs a sudden unexpected acceleration based on at least one of the estimated fuel consumption of each element, information and data. The switching part shuts off an input power of an electronic throttle valve of the vehicle based on an estimation of whether to perform the sudden unexpected acceleration by the control part. 본 발명의 일 실시예에 따른 급발진 방지 장치는 차량의 브레이크 신호 및 차량의 속도, 엔진회전수, 터빈회전수, 가속 페달 개도를 포함하고, 순간 연료 소모량, 흡입 공기 유량, 냉각수온, 엔진오일 온도, 변속기오일 온도, 도로 경사도 및 대기압 중 적어도 하나 이상에 대한 정보를 수집하는 운전정보 수집부, 차량의 중량 및 토크 컨버터 특성 곡선, 상기 차량의 주행저항을 포함하고, 기어 비, 타이어 동반경, 기어 각 단별 마찰력, 엔진 무빙계 이너셔 및 파워트레인 무빙계 이너셔 중 적어도 하나 이상에 대한 데이터를 저장하는 차량특성 저장부, 정보와 데이터에 기초하여 차량의 각 요소 별 연료 소모량을 추정하고, 추정된 연료소모량 중 변속기 슬립손실일 및 가속저항 손실일에 대한 연료소모량을 포함하고 그 외의 상기 추정된 각 요소 별 연료소모량, 정보 및 데이터 중 적어도 하나에 기초하여 차량의 급발진 상태 여부를 판정하는 제어부 및 제어부에 의한 급발진 상태 여부 판정에 기초하여 차량의 전자쓰로틀 모터의 입력 전원을 차단하는 스위칭부를 포함할 수 있다.
