The invention discloses a commercial vehicle hill-start assisting system based on electric control air pressure braking, and a control method thereof. The system comprises a system controller, a firstbrake air chamber, a second brake air chamber, a first ABS electromagnetic valve, a second ABS electromagnetic valve, a proportional relay electromagnetic valve, a first pressure sensor, a second pressure sensor, a third pressure sensor, a first wheel speed sensor, a second wheel speed sensor, a foot valve, an air cylinder, a system switch and a whole vehicle CAN and pressurization channel. The control method comprises the steps of activating the state, judging whether the vehicle state and the brake pressure reach target values or not, taking corresponding actions, judging the brake action of personnel, entering an early warning state and a pressure relief mode and the like. According to the system and the control method, on the premise that the corresponding hill-start assisting effectis achieved, it can be guaranteed that no hardware cost is increased.

    本发明公开了一种基于电控气压制动的商用车坡道起步辅助系统与其控制方法,包括:系统控制器、第一制动气室、第二制动气室、第一ABS电磁阀、第二ABS电磁阀、比例继动电磁阀、第一压力传感器、第二压力传感器、第三压力传感器、第一轮速传感器、第二轮速传感器、脚阀、储气筒、系统开关与整车CAN与增压通道。控制方法则包括:状态激活、判断车辆状态、制动压力是否达目标值并采取相应动作,判断人员制动动作,进入预警状态和泄压模式等步骤。该系统和控制方法在实现相应的坡道起步的辅助作用前提下,可保证不增加任何的硬件成本。
