A vehicle drive force control apparatus configured to make it possible to increase the drive force when the vehicle is accelerating from a stopped condition without increasing the size of its electric generator. In particular, an output of an engine is delivered to the left and right front wheels and to the electric generator. The output voltage of the electric generator is supplied to an electric motor and the output of the electric motor drives the left and right rear wheels. If it is determined that the vehicle is stuck when the vehicle is attempting to accelerate from a stopped condition (starting into motion from a stop), the target slippage amount used for engine TCS control is increased.
