The invention provides a vehicle slip control method and device, a vehicle and a storage medium, the method is applied to the technical field of vehicles, and the method comprises the steps that when it is judged that the vehicle slips based on the current wheel speed and the current reference vehicle speed, a first torque reduction gradient is determined according to the first difference value of the current wheel speed and the current reference vehicle speed, and reducing the output torque of the driving motor to a first target intervention torque based on the first torque reduction gradient, determining a target gradient according to the current request torque of the motor, the wheel speed after falling and the reference vehicle speed after falling when the current wheel speed has a falling trend, and adjusting the output torque of the driving motor based on the target gradient. And until the vehicle meets the slip control quitting condition. According to the method, the control algorithm can be integrated in the motor controller to monitor the wheel slipping state in real time, torque intervention can be conducted in advance, the output torque of the driving motor is dynamically adjusted so as to reduce the situation that the wheels slip again, and then stable output of the vehicle driving force is guaranteed.

    本申请提供了车辆打滑控制方法、装置、车辆及存储介质,该方法应用于车辆技术领域,该方法包括:基于当前轮速和当前参考车速判定车辆存在打滑现象时,根据当前轮速和当前参考车速的第一差值确定第一降扭梯度,并基于第一降扭梯度将驱动电机的输出扭矩降低至第一目标干预扭矩,同时在当前轮速存在下跌趋势时,根据电机当前请求扭矩、下跌后的轮速和下跌后的参考车速确定目标梯度,且基于目标梯度调节驱动电机的输出扭矩,直至车辆满足退出打滑控制条件。该方法能够在电机控制器中集成控制算法以实时监控车轮打滑状态,并可以提前进行扭矩干预,从而动态调整驱动电机的输出扭矩以降低车轮再次出现打滑情况,进而保证车辆驱动力的稳定输出。
