The invention belongs to the technical field of electric vehicles, and discloses a slip prevention method, device and equipment and a storage medium. The method comprises the following steps: acquiring the current speed of a target vehicle; when the current speed is smaller than a speed threshold value, acquiring the rotating speed change degree of a target vehicle motor and the wheel speed change degree of wheels; and adjusting the torque of the target vehicle according to the rotating speed change degree, the wheel speed change degree and the current speed, so that the target vehicle is prevented from slipping. In this way, whether the anti-skid strategy needs to be started or not is judged according to the current speed of the target vehicle, when the current speed is smaller than the speed threshold value, the rotating speed change degree and the wheel speed change degree are determined according to the motor rotating speed and the wheel speed, and the rotating speed change degree and the wheel speed change degree are compared with the boundary change degree; therefore, whether the torque needs to be adjusted or not is judged, and therefore it is guaranteed that the vehicle can be accelerated stably and cannot slip easily.

    本发明属于电动汽车技术领域,公开了一种预防打滑方法、装置、设备及存储介质。该方法包括:获取目标车辆的当前速度;当所述当前速度小于速度阈值时,获取目标车辆电机的转速变化程度以及车轮的轮速变化程度;根据所述转速变化程度、所述轮速变化程度以及所述当前速度调节所述目标车辆的扭矩,以防止所述目标车辆打滑。通过上述方式,本发明根据目标车辆的当前速度判断是否需要开启防滑策略,在当前速度小于速度阈值时,根据电机转速以及车轮轮速确定转速变化程度以及轮速变化程度,并将转速变化程度以及轮速变化程度与边界变化程度进行比较,以此判断是否需要进行调节扭矩,从而保证了车辆可以平稳加速而不会轻易发生打滑。
