    Abstract: An acceleration slip regulation method and device for a four-wheel drive electric vehicle are disclosed. The method comprises the following steps: detecting wheel speeds of four wheels of an electric vehicle and a depth of depression of an accelerator pedal; estimating a vehicle speed of the electric vehicle according to the wheel speeds of the four wheels, determining a road condition at the location of the electric vehicle according to the wheel speeds of the four wheels and the vehicle speed, and acquiring a required torque of the electric vehicle according to the depth of depression of the accelerator pedal, wherein the road condition comprising a low adhesion starting road, a joint road, and a bisectional road; and performing acceleration slip regulation on the four wheels respectively according to the road condition and the required torque. The control method can ensure that the wheels do not slip, the electric vehicle does not undergo lateral displacement and a yaw rate is kept within a certain range after the electric vehicle activates acceleration slip. The control method can maximize the use of ground adhesion to improve the escape capability of the electric vehicle.
