<P>PROBLEM TO BE SOLVED: To efficiently start an engine, even if electric energy that can be supplied from a power storage device is small. <P>SOLUTION: During an inertial energy storage operation, electric power conversion at an inverter 40 is controlled such that a direct current electric power from an electric power storage device 42 is converted into an alternating current by the inverter 40 to be supplied to stator windings 20, such that torque in the direction of engine rotation is applied to an output side rotor 18 from a stator 16 to rotatively drive the output side rotor 18 in a state where power transmission from the output side rotor 18 to a drive axle 37 is stopped. During a cranking operation after the inertial energy storage operation, the electric power conversion at an inverter 41 is controlled to permit application of the alternating current to rotor windings 30, such that a torque in the direction of engine rotation is applied to an input side rotor 28 from the output side rotor 18, thereby rotatively driving an input side rotor 28 to crank the engine 36. <P>COPYRIGHT: (C)2013,JPO&INPIT |
