Abstract

본 발명은 자동차의 제동력 유지장치에 관한 것으로, 제동 이후 브레이크 페달을 해제시킨 상태에서도 제동력이 유지되고, 이후 출발을 위하여 가속페달을 밟으면 동시에 제동상태가 해제되도록 된 자동차의 제동력 유지장치를 제공하는 것을 그 목적으로 하며, 전자제어유닛(12)과, 제동을 위한 작동유체를 이송시키기 위한 브레이크 파이프(1)와, 상기 브레이크 파이프(1)의 통로를 개폐시키기 위한 피스톤밸브(2), 상기 피스톤밸브(2)를 작동시키되 그 피스톤밸브(2)가 자동차의 정지시에 상기 브레이크파이프(1)의 통로를 폐쇄시키고 정지후 재출발을 위하여 가속페달을 밟을때 개방되도록 하는 전자제어유닛(12)의 신호를 받아 작동되는 솔레노이드(3)를 구비하여 구성되는 것을 특징으로 한다.The present invention relates to a braking force maintenance device for a vehicle, wherein the braking force is maintained even when the brake pedal is released after braking, and then, when the accelerator pedal is pressed for starting, the braking force maintenance device of the vehicle is released at the same time. To this end, the electronic control unit 12, the brake pipe (1) for transporting the working fluid for braking, the piston valve (2) for opening and closing the passage of the brake pipe (1), the piston valve Signal of the electronic control unit 12 which activates (2) the piston valve (2) to close the passage of the brake pipe (1) when the vehicle is stopped and open when the accelerator pedal is pressed for restarting after stopping; It characterized in that the configuration is provided with a solenoid (3) to operate.
