The embodiment of the invention discloses a control method for wheel slipping. The control method specifically comprises the following steps: acquiring a first rotating speed change rate output by a power assembly system under the current output torque of a vehicle; if the first rotating speed change rate is greater than a standard rotating speed change rate, determining that the wheels of the vehicle slip, the standard rotating speed change rate being obtained on the basis of the corresponding relation between a pre-configured output torque and a rotating speed change rate output by the powerassembly system under the output torque; and reducing the rotating speed of the output shafts of a first output half shaft and a second output half shaft to a first preset value, and controlling thefirst output half shaft and the second output half shaft on the two sides of an inter-wheel differential lock to be fixed by utilizing the inter-wheel differential lock connected with the first outputhalf shaft so as to control the wheels to prevent slipping. The vehicle can recover the driving capability as soon as possible and get out of trouble. Meanwhile, the loss of the tire during slippingis reduced, and the service life of the wheel is prolonged. The embodiment of the invention further discloses a control system for wheel slipping.
