A driving force controlling apparatus for a vehicle including an electric generator and a motor for driving a wheel other than a driving wheel, with electric power from the electric generator, includes a requested electric power computing means that computes requested electric power required for operation of the motor. Target output of the electric generator is set based on the requested electric power and maximum output that the electric generator can output stably. The driving force controlling apparatus for a vehicle including the motor for driving a wheel other than a driving wheel driven by an engine, with electric power from the electric generator, enables the electric generator to stably output electric power.
