Control method of limited slip differential, vehicle anti-skid system and vehicle

The invention relates to a control method of a limited slip differential, a vehicle anti-skid system and a vehicle. The control method comprises the steps that at least one parameter indicating whether the limited slip differential is in a first state or not is obtained; and a controller of the limited slip differential sends a signal to the instrument panel based on the at least one parameter and displays prompt information, wherein in the first state, the limited slip differential cannot reach the preset locking torque, the at least one parameter comprises the vehicle inclination angle alpha and the wheel speed difference delta V = V1-V2, V1 is the rotating speed of a left wheel, and V2 is the rotating speed of a right wheel. Thus, a driver is prompted that the limited slip differential cannot work normally through prompt information, that is, an oil suction port of the limited slip differential cannot suck oil and establish oil pressure, the limited slip differential cannot reach the required locking torqu
