The present invention relates to a device for preventing sudden acceleration. The present invention provides a device for preventing sudden acceleration of a vehicle, comprising: a vehicle power supply unit that supplies power to the vehicle; a fuel pump; an Accelerator Position Sensor (APS); a plurality of ECUs including an engine ECU connected to an internal vehicle communication network; and an OBD terminal that provides vehicle status information. Disclosed is the sudden acceleration prevention device, characterized by including: a control unit that receives vehicle status information including an engine rpm value and an accelerator output value according to the degree of pressing the accelerator from the vehicle without using an internal communication network, determines whether sudden acceleration occurs, and generates an engine ECU data deletion signal if sudden acceleration is determined; and a first power switch that is installed between the vehicle power supply unit and the engine ECU and deletes data accumulated in the engine ECU according to the engine ECU data deletion signal. The sudden acceleration prevention device according to the present invention can be implemented with a small number of circuit components and operates independently from the vehicle's internal communication network, thereby stably preventing sudden acceleration of the vehicle.
본 발명은 급발진 방지 장치에 관한 것이다. 본 발명에서는 차량에 전원을 공급하는 차량 전원부, 연료펌프, APS(Accelator Position Sensor), 차량 내부 통신망에 연결된 엔진 ECU를 포함한 복수 개 ECU 및 차량 상태 정보를 제공하는 OBD 단자를 구비하는 차량의 급발진을 방지하는 장치에 있어서, 내부 통신망을 이용함이 없이 상기 차량으로부터 엔진 rpm 값 및 엑셀레이터 밟은 정도에 따른 엑셀출력값을 포함하는 차량 상태 정보를 입력받아 급발진 여부를 판별하고 급발진이라 판별될 경우 엔진 ECU 데이터삭제신호를 생성하는 제어부; 및 차량 전원부와 상기 엔진 ECU 사이에 설치되며 상기 엔진 ECU 데이터삭제신호에 따라 상기 엔진 ECU에 축적된 데이터를 삭제하는 제1전원스위치를 포함하는 것을 특징으로 하는 급발진 방지 장치가 개시된다. 본 발명에 따른 급발진 방지 장치에 의하면 적은 회로부품으로 구현할 수 있으며 차량 내부 통신망과 독립적으로 동작되어 안정적으로 차량의 급발진을 방지할 수 있게 되었다.
