PROBLEM TO BE SOLVED: To reduce the maximum load capacity of an assist motor, and the maximum current value in an inverter circuit for driving the assist motor. SOLUTION: A control unit sets a WOT(wide open throttle) line as a boundary between over and under drive regions when the secured condition of the assist motor is in the over drive securing condition (S104). The control unit decides the target action point of an outer rotor shaft that is a driving shaft from requirement output (S106), and when the target action point is in the under drive region, a WOT line where engine torque can be made maximum is selected as the action line of an engine (S116), to raise a switch flag from over to under drive securing (S118). Consequently switching is made from the over to under drive securing, and the WOT line can be used as the engine action line when the action point of the outer rotor shaft, that is a driving shaft, is in the under drive region. |
