Abstract
A driving force control apparatus includes a first torque calculator configured to calculate turning radius correspondence torques indicating the magnitudes of the driving forces to be transmitted to a right rear wheel and a left rear wheel based on a turning radius, a second torque calculator configured to calculate steering velocity response torques based on a steering velocity of a steering wheel and a vehicle speed, a corrector configured to calculate a corrected torque by correcting a turning radius correspondence torque of at least one of wheels on an inner side of turning and on an outer side of turning in accordance with the steering velocity response torque, and a current controller configured to supply currents to torque couplings so that driving forces based on the corrected torque are transmitted.
