The invention provides a torque control method, a vehicle and a computer readable storage medium. The torque control method comprises the steps that whether the vehicle is in a ramp running condition or not is judged; if yes, obtaining a target torque adjustment coefficient of each wheel of the vehicle and the maximum available torque of each wheel; obtaining a target output torque corresponding to each wheel according to the maximum available torque of each wheel and the target torque adjustment coefficient of each wheel; and distributing torque to the corresponding wheels according to the target output torque of each wheel. According to the method, the slip rate of each wheel of the vehicle is changed within an acceptable range, accurate control over the slip rate of each wheel of the vehicle is achieved, the problem that the stability of vehicle operation is affected due to large fluctuation of the slip rate is solved, the vehicle operation stability is enhanced, each wheel is kept at the target output torque, and the service life of the vehicle is prolonged. Therefore, vehicle kinetic energy waste is effectively reduced, and the endurance mileage of the vehicle is increased.

    本发明提出一种扭矩控制方法、车辆和计算机可读存储介质,方法包括:判断车辆是否处于坡道行驶工况;若是,则获取车辆各车轮的目标扭矩调整系数及各车轮的最大可用扭矩;根据各车轮的最大可用扭矩及各车轮的目标扭矩调整系数,得到对应于各车轮的目标输出扭矩;根据各车轮的目标输出扭矩对相应车轮分配扭矩。本发明使得车辆各车轮的滑移率在可接受范围内变动,实现对车辆各车轮的滑移率的精准控制,减少滑移率波动较大而影响车辆操作的稳定性的问题,从而增强车辆操纵稳定性,并且使各车轮保持在目标输出扭矩,从而有效降低车辆动能浪费,增加车辆的续航里程。
