According to one embodiment of the present invention, a device for controlling sudden acceleration comprises: a sensor sensing current acceleration of a vehicle; a first control unit calculating a command value of motor torque for driving of a motor, calculating predicted acceleration of the vehicle based on the command value of the motor torque, and comparing the predicted acceleration with the current acceleration; and a second control unit comparing the command value of the motor torque with a preset value. The present invention determines a factor inducing sudden acceleration and blocks the sudden acceleration according to a determination result to improve safety of a driver.
본 발명의 일 실시예에 따른 급발진 제어 장치는 차량의 현재 가속도를 감지하는 센서와, 모터의 구동을 위한 모터토크 지령값을 연산하고, 상기 모터토크 지령값을 기반으로 차량의 예상 가속도를 연산하며, 상기 예상 가속도와 상기 현재 가속도를 비교하는 제1 제어부 및 상기 모터토크 지령값을 기 설정된 값과 비교하는 제2 제어부를 포함하여, 급발진을 유발하는 원인을 판단하고, 판단 결과에 따라 급발진을 차단하여, 운전자의 안전을 향상시킬 수 있다.
