본 발명은 EHS시스템 구현을 위해 필요한 부품을 간소화하여 원가를 절감하면서도 경사로에서의 밀림 현상을 근본적으로 방지하는 기술에 관한 것으로, 본 발명에서는, 브레이크페달의 제동작동에 따라 에어탱크의 압축공기가 브레이크밸브와 더블체크밸브를 거쳐 브레이크챔버에 전달되도록 형성된 브레이크공압라인; EHS의 작동에 따라 에어탱크의 압축공기가 솔레노이드밸브와 더블체크밸브를 거쳐 브레이크챔버에 전달되도록 형성된 EHS공압라인; 솔레노이드밸브와 더블체크밸브 사이의 압력을 측정하는 압력센서; 및 EHS가 작동된 상태에서 브레이크페달의 해제시, 솔레노이드밸브와 더블체크밸브 사이의 압력 측정값이 경사로 정지를 위해 세팅된 타겟값에 도달 및 유지되도록 솔레노이드밸브를 제어하는 컨트롤러;를 포함하는 경사로 발진 보조시스템 및 그 제어방법이 소개된다.

    The present invention relates to a technology for fundamentally preventing the phenomenon of being pushed on a hill while simplifying the parts needed for realizing an EHS system and reducing the cost. According to the present invention, disclosed are a hill start assist system and a control method thereof, wherein the hill start assist system comprises: a brake pneumatic line in which compressed air of an air tank is transferred to a brake chamber by passing through a brake valve and a double check valve in accordance with the braking operation of a brake pedal; an EHS pneumatic line in which compressed air of the air tank is transferred to the brake chamber by passing through a solenoid valve and the double check valve in accordance with the operation of the EHS; a pressure sensor which measures the pressure between the solenoid valve and the double check valve; and a controller which controls the solenoid valve so that, when the brake pedal is released with the EHS operating, the pressure measurement value between the solenoid valve and the double check valve reaches and maintains a set target value for stopping at the hill.
