Abstract

A control system for a vehicle having two motors is provided to limit damage on rotary members even if an excessive torque is applied from drive wheels. The control system comprises a first motor, a second motor, and a locking mechanism, and a differential mechanism disposed between the first motor and the drive wheels. The locking mechanism halts one of rotary elements of a differential mechanism when torque of the rotary member is small, and allows the rotary element to rotate when the torque of the rotary member is large. A controller is configured to increase power output of the first motor and decrease power output of the second motor during propulsion on an uneven road surface.
