Abstract: PROBLEM TO BE SOLVED: To give preference to responsiveness of driving force in a power mode, and to give preference to mileage in an economy mode. SOLUTION: A driving mode is decided based on an input mode setting signal MSW (steps S400-S410), a power threshold value smaller than the normal mode is set, when the driving mode is the power mode; a power threshold larger than that of the normal mode is set, when the driving mode is economy mode (steps S420-S440); intermittent operation of an engine is inhibited, when required power Pe* required to a driving axle is the set power threshold or above, and the intermittent operation of the engine is permitted, when it is smaller than the power threshold for performing traveling. Accordingly, the intermittent operation of the engine is inhibited in the power mode, because it is often the case that the engine is operated, so that the responsiveness of the driving force is improved. The intermittent operation of the engine is permitted in the economy mode, and it is often the case that the engine can be stopped, so that the mileage is improved. COPYRIGHT: (C)2009,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To resolve gear noises without worsening fuel consumption in the self-sustaining operation of an internal-combustion engine in a power output device with a transmission capable of disconnecting between a power shaft and a drive shaft in addition to an electric motor outputting power to the power shaft. SOLUTION: During self-sustaining operation of an engine, if a shift position is at an N position and an SOC of a battery is not smaller than a prescribed threshold (affirmative determination in S120, S130), the target number of rotations Ne* of the engine is set to the number of idle rotations Nidl, the target number of rotations Nm1* of a motor MG1 is set to the positive number of rotations, and the target number of rotations Nm2* of a motor MG2 is set to the negative number of rotations (Step 140). In this way, during the self-sustaining operation of the engine, it is possible to prevent the occurrence of gear noises due to torque variations of the engine and prevent a deterioration in fuel consumption by rotating the motor MG2 without having to increase the number of idle rotations Nidl of the engine.
