A driving force control apparatus is provided to optimize the acceleration performance and improve the energy efficiency of a vehicle. Preferably, the front wheels are driven by the internal combustion engine, while the rear wheels are driven by the electric motor. The electric motor is driven by electrical power generated by the generator. The generator is driven by the engine. When acceleration slippage occurs in the front wheels, the generator is controlled so as to produce a generation load torque corresponding to the acceleration slippage magnitude.
