The invention discloses a vehicle hill starting control method, a storage medium, a controller and a vehicle, and the method comprises the following steps: after determining that the vehicle enters a hill starting mode, obtaining the load of the vehicle, the gradient of a road where the vehicle is located and a road adhesion coefficient in real time; according to the gradient, the load and the road adhesion coefficient, a target braking force, a target slip rate and a target driving force are obtained; and the vehicle is controlled according to the target braking force, the target slip rate and the target driving force until it is determined that the vehicle completes hill starting. According to the method, the conditions of ramp angle change, road adhesion coefficient change, vehicle load change and the like existing in the slope starting process of a vehicle are fully considered, the gradient, the load and the road adhesion coefficient are obtained in real time, the target slip rate, the target driving force and the target braking force are calculated, and the driving strategy is adjusted according to the corresponding road conditions; and the stability, the safety and the driving comfort of the vehicle during hill starting are ensured.

    本发明公开了一种车辆坡道起步控制方法及存储介质、控制器、车辆,该方法包括:确定车辆进入坡道起步模式后,实时获取车辆的荷载、车辆所处道路的坡度和路面附着系数;根据坡度、荷载和路面附着系数,得到目标制动力、目标滑移率和目标驱动力;根据目标制动力、目标滑移率和目标驱动力对车辆进行控制,直至确定车辆完成坡道起步。该方法充分考虑到车辆在坡起过程中存在的坡道角度变化、路面附着系数变化、车辆荷载变化等情况,实时获取坡度、荷载、路面附着系数,并计算目标滑移率、目标驱动力、目标制动力,以对应路况调整驱动策略,保证了车辆在坡道起步时的稳定性、安全性以及驾驶舒适性。
