Abstract

유압라인의 누유시 자동으로 엔진의 출력을 저감시켜 차량의 주행속도를 낮추는 제동력에 따른 차속 제한장치는 차속센서(S1)와, 휠 스피드 센서(S2)와, 브레이크 스위치(S3)와, 브레이크 압력센서 (S4)를 통해 차량의 주행속도 및 브레이크 오일압력을 감지하는 검출부(S)와, 검출부(S)에서 검출된 차량의 주행속도와 브레이크 오일압력 및 종가속도를 바탕으로 브레이크 라인압력 및 제동거리를 비교 연산하는 제어부(C)와, 제어부(C)에서 전달되는 신호에 따라 보조 드로틀 밸브(24)를 선택적으로 개폐하여 흡입 공기량을 제어하는 구동부(D)로 이루어져 있으며, 컨트롤 유닛(32)은 검출부(S)에서 전달된 신호를 바탕으로 비교 연산하여, 드로틀 밸브 구동모터(26)에 전달하여, 드로틀 밸브(24)를 닫아 흡입 공기량을 조절한다.The vehicle speed limiting device according to the braking force that automatically reduces the engine output when the hydraulic line is leaked and lowers the running speed of the vehicle may include a vehicle speed sensor S1, a wheel speed sensor S2, a brake switch S3, and a brake pressure. Detecting unit S for detecting the traveling speed and the brake oil pressure of the vehicle through the sensor S4, and the brake line pressure and the braking distance based on the traveling speed, the brake oil pressure and the longitudinal acceleration of the vehicle detected by the detecting unit S. The control unit (C) for comparing the operation and the drive unit (D) for controlling the intake air amount by selectively opening and closing the auxiliary throttle valve (24) in accordance with the signal transmitted from the control unit (C), the control unit 32 The comparison operation is performed based on the signal transmitted from the detection unit S, and is transferred to the throttle valve driving motor 26 to close the throttle valve 24 to adjust the intake air amount.
