ABSTRACT:
A driving force distribution control system for a vehicle includes a torque distributing clutch for varying a driving force transmitted to a secondary drive wheels in response to a control signal, sensors for determining a wheel speed difference between the wheel speed of primary drive wheels and the wheel speed of the secondary drive wheels, and a longitudinal acceleration, and a control unit for controlling the clutch engagement force of the torque distributing clutch by producing the control signal. The control unit has a first control mode for normally controlling the clutch engagement force in accordance with the wheel speed difference, and a second control mode for controlling the clutch engagement force in accordance with the longitudinal acceleration so as to prevent undesired hunting when a wheel spin of the primary or secondary drive wheels is detected.
