The invention relates to the technical field of vehicles, and particularly relates to an anti-slip control method and device for an electric vehicle, a vehicle and a storage medium. The method comprises the steps that the actual rotating speed of a driving motor of the electric vehicle is collected, and the current rotating speed change rate of the driving motor is calculated according to the actual rotating speed; and the current working condition of the electric vehicle is identified based on a current rotating speed change rate, if the current working condition is a slip working condition, a corresponding current torque reduction coefficient according to the current rotating speed change rate is calculated, and the current target torque of the electric vehicle is optimized by using the current torque reduction coefficient. Therefore, the technical problems that in the related technology, due to the fact that too many parts are used, the accuracy of slip control is low, the reliability and safety of the vehicle are greatly reduced, and the user experience is poor are solved.
本申请涉及车辆技术领域,特别涉及一种电动汽车的防打滑控制方法、装置、车辆及存储介质,其中,方法包括:采集电动汽车的驱动电机的实际转速,根据实际转速计算驱动电机的当前转速变化率,并基于当前转速变化率识别电动汽车的当前工况,以及若当前工况为打滑工况,则由当前转速变化率计算对应的当前降扭系数,利用当前降扭系数优化电动汽车的当前目标扭矩。由此,解决了相关技术中使用部件过多,导致打滑控制的准确性较低,大大降低了车辆的可靠性和安全性,用户体验较差的技术问题。
