ABSTRACT:
A first motor generator is linked to an engine and generates torque to start the engine. At time t1-t2and time t3-t4, when current conducted to the first motor generator will exceed the upper limit value and the lower limit value due to the increase of the absolute value of a current component required to conduct alternating current across neutral points of first and second motor generators, a control device corrects a torque control value of the first motor generator such that the torque current component of the first motor generator directed to starting the engine is reduced.
