본 발명은 구동륜의 구동 토크를 제어할 때, 차량 거동을 안정시키는 것이 가능한 구동력 제어 장치를 제공하는 것을 과제로 한다. 차량의 구동륜에 감속 기구 및 구동축을 통해 접속하여, 구동륜을 제구동하는 토크를 발생시키는 구동원의 구동 토크를 감소시켜 구동륜의 슬립 상태를 억제하는 슬립 억제 제어를 행할 때에, 구동륜의 슬립률이, 슬립률에 대한 노면 마찰 계수의 특성에 있어서 노면 마찰 계수의 피크값의 슬립률보다 작은 슬립률의 영역이 되도록 구동원의 구동 토크를 제어하는 것으로 한다.
Provided is a driving force control device capable of stabilizing a vehicle behavior when a driving torque of a drive wheel is controlled. When slip suppression control is carried out to decrease a driving torque of a drive source that is connected to the drive wheel of a vehicle via a speed reduction mechanism and a drive shaft, and is configured to generate a torque for braking or driving the drive wheel, to thereby suppress a slip state of the drive wheel, the driving torque of the drive source is controlled so that a slip ratio of the drive wheel is in an area of the slip ratio smaller than a slip ratio corresponding to a peak value of a road surface friction coefficient in a characteristic of the road surface friction coefficient with respect to the slip ratio.
