The present invention relates to a wheel slip control method for a vehicle and, more specifically, to a wheel slip control method for a vehicle, which allows wheel slip to be suppressed in a vehicle having an open differential without unnecessary reduction in driving force. The wheel slip control method for a vehicle according to the present invention comprises the following steps of: allowing a control unit to estimate information on equivalent inertia of a driving system, based on information on the operation of the driving system while the vehicle travels; allowing the control unit to determine whether slip of a driving wheel occurs, based on the estimated information on equivalent inertia of the driving system; allowing the control unit to determine whether there is a side wheel slip where the slip occurs only in any one of a left-sided wheel and a right-sided wheel of the driving wheels from speeds of the left-sided wheel and right-sided wheel sensed by a sensor when the slip in the driving wheel is considered to have occurred; and allowing the control unit to control the operation of a braking device such that braking force is applied to the wheel where the slip has occurred when the side wheel slip is considered to have occurred.

    본 발명은 차량의 휠 슬립 제어 방법에 관한 것으로서, 오픈 디퍼렌셜이 장착된 차량에서 불필요한 구동력 저감 없이 휠 슬립 억제가 가능해지는 차량의 휠 슬립 제어 방법을 제공하는데 주된 목적이 있는 것이다. 상기한 목적을 달성하기 위해, 차량의 주행 중 제어부에서 구동계의 작동 정보에 기초하여 구동계의 등가관성 정보를 추정하는 단계; 제어부가 상기 추정된 구동계의 등가관성 정보로부터 구동륜의 슬립 발생 여부를 판단하는 단계; 구동륜의 슬립이 발생한 것으로 판단한 경우, 제어부가 센서에 의해 검출되는 좌측륜 속도와 우측륜 속도로부터 상기 구동륜의 좌측륜과 우측륜 중 어느 하나의 차륜에만 슬립이 발생한 편휠슬립 상태인지를 판단하는 단계: 및 편휠슬립 상태인 것으로 판단한 경우, 제어부가 슬립이 발생한 차륜에 제동력이 인가되도록 제동장치의 작동을 제어하는 단계를 포함하는 차량의 휠 슬립 제어 방법이 개시된다.
