The invention provides a sliding recovery control method, a vehicle control unit and an electric vehicle. The method comprises the steps that when it is monitored that the electric vehicle is in a sliding recovery working condition, target sliding torques of a front driving motor and a rear driving motor of the electric vehicle are determined according to a first state parameter of the electric vehicle, and the target sliding torques of the front driving motor and the rear driving motor are determined according to the target sliding torques of the front driving motor and the rear driving motor; respectively controlling a front driving motor and a rear driving motor of the electric automobile to slide and recover; and according to the second state parameter of the electric vehicle, whether hydraulic braking compensation is carried out or not is determined, and when it is determined that hydraulic braking compensation is carried out, a hydraulic braking compensation request is sent to a braking controller of the electric vehicle, so that the braking controller controls wheels of the electric vehicle to carry out hydraulic braking. According to the method provided by the invention, the time delay of the control link can be shortened, the control accuracy is improved, and the braking overshoot is more effectively avoided.
