The invention provides a driving torque determination method, a vehicle and a storage medium, and belongs to the technical field of automobiles, and the method comprises the steps that when the vehicle is in a slope driving working condition, the target slip rate of the vehicle is determined according to the current vehicle speed of the vehicle and the road gradient and friction coefficient of a road where the vehicle is located, the target slip rate is a critical slip rate at which the vehicle does not slip under the conditions of vehicle speed, road gradient and friction coefficient; in response to activation of the slip control module corresponding to any wheel, determining a target wheel speed according to the target slip rate; and according to the wheel speed error between the target wheel speed and the actual wheel speed, the first driving torque of the slipping wheel is determined, and the first driving torque is used for providing longitudinal climbing power for the wheel. According to the scheme, slipping of the vehicle is prevented, and meanwhile the climbing power of the vehicle is guaranteed.
本申请提供了一种驱动扭矩确定方法、车辆和存储介质,属于汽车技术领域,该方法包括:当车辆处于斜坡驾驶工况时,根据车辆当前的车速、车辆所在道路的道路坡度和摩擦系数,确定车辆的目标滑移率,目标滑移率为车辆在车速、道路坡度和摩擦系数下,不发生打滑现象的临界滑移率;响应于任一车轮对应的滑移控制模块激活,根据目标滑移率,确定目标轮速;根据目标轮速和实际轮速的轮速误差,确定发生打滑的车轮的第一驱动扭矩,第一驱动扭矩用于为车轮提供纵向爬坡动力。通过本方案,防止了车辆发生打滑的同时,保证了车辆的爬坡动力。
