Abstract
A torque applied to a one-way clutch when a first motor generator and second motor generator are operated in a motor generator drive mode is restrained or prevented from becoming excessively high by setting a first motor generator sharing ratio in response to a driving torque target for the vehicle, by controlling operation of the first motor generator in response to a first motor generator first sharing ratio when vehicle vibrations due to cogging torque are likely to take place, and by reducing the torque from the first motor generator when the driving torque target is large. Torque applied to the one-way clutch which otherwise would become excessively high immediately after engine shutdown, is restrained or prevented by reducing the torque from the first motor generator in response to a second motor generator second sharing ratio when engine downtime is short.
