  • Patent number: 8577526
    Abstract: In a hybrid vehicle 20, when the ECO switch 88 is turned on, Step S140 determines whether or not a driving state is an economy driving state based on an ECO mode driving state determination map having a tendency not to regard the driving state as the economy driving state in comparison with a normal driving state determination map. A determination result of Step S140 is displayed on a meter display unit 90 in the form of an illumination or an extinction of an ECO mark 95 so as to inform the driving state is the economy driving state or not (Step S180).

  • Patent number: 8271156
    Abstract: When determined that a driver's accelerator operation is rough during the turn-on condition of an ECO switch 88 while a hybrid vehicle 20 is driven without an operation of an engine 22 (Step S120), a threshold value Pref with respect to a power demand P* is set to a value P2 that is larger than a value P1 of the turn-off condition of the ECO switch 88 so as to give priority to fuel consumption of the engine 22 (Step S140). Then, the engine 22, motors MG1 and MG2 are controlled with a start of the engine 22 as necessary so as to ensure torque equivalent to a torque demand Tr* (Steps S150-S230).

  • Patent number: 8065069
    Abstract: In a hybrid vehicle 20, when an ECO switch 88 is turned off while an intermittent operation of an engine 22 is prohibited in response to a warm-up demand of the engine 22 according to a cooling water temperature Tw or a heating demand, the engine 22 is autonomously operated at a target rotational speed Ne* derived and set from a normal autonomous rotational speed setting map (Steps 170, S190). When the ECO switch 88 is turned on while the warm-up is demanded, the engine 22 is autonomously operated at the target rotational speed Ne* set based on an ECO mode autonomous rotational speed setting map so as to be not more than the value derived from the normal autonomous rotational speed setting map (Steps 180, S190).
