TL;DR: In this article, the engine and motors are controlled to suppress vibration resulting from torque pulsation occurring in a crankshaft due to damping torque (Tv) from the motor (MG1) and to output a demand torque (Tr*) to a ring gear shaft (32a) (S140-S250).

TL;DR: In this article, when the ECO switch 88 is turned on, a maximum allowable charging power Pcmax is set based on a vehicle speed and an ECO mode maximum allowable Charging Power Setting Map that is a second relationship having a tendency to allow charging of a battery 50 in comparison with a normal maximum allowable charge power setting map (Step S 130 ), and an engine 22, motors MG 1 and MG 2 are controlled so that the battery 50 is charged with an effective charge-discharge power demand Pb* as a charging power demand set at Step S 140 in accordance with

TL;DR: In this article, a threshold value Pref with respect to a power demand P* is set to a value P 2 that is larger than a value Pref P 1 of the turn-off condition of the ECO switch 88 so as to give priority to fuel consumption of the engine 22.

TL;DR: In this paper, the authors propose an approach to enable a driver to select whether priority is given to improving the energy efficiency of a vehicle when in outputting a creep torque. But, they do not consider the effect of the driver's pedal application force on the target creep torque Tcr*, as compared to normal creep torque setting maps.

TL;DR: In this article, a threshold value Pref for a request power P* is set to a value P2 which is greater than a valueP1 when the ECO switch (88) is OFF (step S140) so as to improve the fuel consumption of the engine (22) with a higher priority.
