Abstract

A vehicle drive system configured to achieve a required driving force of braking force without changing an orientation of a vehicle in the event of slippage of a wheel. The vehicle drive system comprises: a torque generating device; a differential mechanism that allows a relative rotation between a right wheel and a left wheel; a differential restricting device that restricts a differential rotation between the right wheel and the left wheel; and a steering mechanism that controls a turning angle of pairs of the wheels. A first controller controls the relative rotation between the right wheel and the left wheel to be smaller than a predetermined value and second controller further controls a turning angle of the wheels controlled by the steering mechanism.
