ABSTRACT:
A vehicle driving force control apparatus is provided for a vehicle to prevent a shock from being generated when a clutch disposed between a subordinate drive source and subordinate drive wheels is transferred to a disengaged state during vehicle travel. When a transition is made from a four-wheel drive state to a two-wheel drive state, and a clutch is released during vehicle travel, the motor torque is maintained constant at a level of a clutch-release torque required by the electric motor as the output for bringing the torque on the clutch substantially to zero.
