摘要： PROBLEM TO BE SOLVED: To give priority to the responsiveness of a driving force in a power mode, and to give priority to fuel consumption in an eco-mode. SOLUTION: This power output device is configured to decide a driving mode based on an input mode setting signal MSW (S400 to S410), and to set an intermittent inhibition value which is larger than that in a normal mode when the driving mode is a power mode, and to set an intermittent inhibition value which is smaller than that in a normal mode (S420 to S440) when the driving mode is an eco-mode, and to inhibit the intermittent operation of an engine when the output restriction Wout of a battery is smaller than an intermittent inhibition value, and when the output restriction Wout of a battery is equal to or larger than the intermittent inhibition value, to permit the intermittent operation of an engine for making a vehicle travel. Thus, it is possible to improve the responsiveness of a driving force since the intermittent driving of the engine is inhibited, and the engine is made to frequently operate in the power mode. Also, it is possible to improve fuel consumption since the intermittent operation of the engine is permitted, and the engine is made to frequently stop in the eco-mode. COPYRIGHT: (C)2009,JPO&INPIT
