A wheel slip control method for a vehicle is provided, and includes estimating equivalent inertia information of a driving system based on operation information of the driving system while a vehicle travels, determining whether the slip of a drive wheel occurs from the estimated equivalent inertia information of the driving system, determining whether the drive wheel is in an uneven wheel slip state where the slip occurs only in one of a left wheel and a right wheel of the drive wheel from a left wheel speed and a right wheel speed detected by a sensor, if it is determined that the slip of the drive wheel occurs, and controlling an operation of a braking device such that a braking force is applied to the vehicle wheel in which the slip occurs, if it is determined that the vehicle wheel is in the uneven wheel slip state.

Wheel slip control method of vehicle

A control method includes calculating a roll angle and a roll angular velocity of a vehicle, setting damping forces applied to front and rear wheel dampers to execute first and second modes according to signs of the roll angle and roll angular velocity, and controlling the front and rear wheel dampers in consideration of the damping forces. Upon determination that the signs of the roll angle and the roll angular velocity are different, in the first mode, damping force greater than front wheel reference force and damping force smaller than rear wheel reference force are set to be applied to the front wheel dampers and the rear wheel dampers, respectively, and in the second mode, damping force smaller than the front wheel reference force and damping force greater than the rear wheel reference force are set to be applied to the front wheel dampers and the rear wheel dampers, respectively.
