The invention provides an air braking electronic parking hill starting auxiliary control method and system, and the method comprises the following steps: obtaining the real-time weight of a vehicle and the type of a road surface where the vehicle is located, and judging whether the vehicle is on a ramp or not; if yes, the vehicle is in a parking state, the torque of the driving motor is increased, and the pneumatic braking electronic parking hill starting auxiliary control system automatically executes; calculating friction force according to the real-time weight of the vehicle and the road surface type, and calculating reverse traction force generated by the vehicle according to the gradient of the ramp where the vehicle is located; and judging whether the traction force generated by the current driving motor torque is greater than the reverse traction force, if so, performing parking release, and if not, automatically compensating the torque by the pneumatic braking electronic parking hill starting auxiliary control system, and performing parking release. Information is comprehensively obtained, automatic execution and automatic judgment are achieved, torque is automatically compensated when traction force is insufficient, and the problem that a vehicle slides on a ramp is solved.

    本发明提供一种气制动电子驻车坡道起步辅助控制方法及控制系统,包括如下步骤:获取车辆实时重量以及车辆所处路面类型,并判断车辆是否在坡道上;若是,车辆为驻车状态,驱动电机扭矩上升,气制动电子驻车坡道起步辅助控制系统自动执行;根据车辆实时重量以及路面类型计算摩擦力,并结合车辆所处坡道的坡度计算车辆产生的反向牵引力;判断当前驱动电机扭矩产生的牵引力是否大于反向牵引力,若是,驻车释放,若否,气制动电子驻车坡道起步辅助控制系统自动补偿扭矩,驻车释放。本发明综合获取信息,自动执行、自动判断,牵引力不足时自动补偿扭矩,解决了车辆在坡道上的溜车问题。
