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).

12. A vehicle including an internal combustion engine capable of outputting power for driving and performing an intermittent operation, the vehicle comprising:
-
a fuel consumption priority mode selection switch to select a fuel consumption priority mode that gives priority to fuel consumption; an intermittent permission determining module that prohibits the intermittent operation of internal combustion engine at least one of when a warm up of the internal combustion engine is necessary and when a heating is demanded of a heater that heats a vehicle room through the use of the internal combustion engine as a heat source; and an intermittent prohibition control module configured to control the internal combustion engine so as to autonomously operate at a first autonomous rotational speed when the fuel consumption priority mode selection switch is turned off during an intermittent operation prohibition in which the intermittent operation of the internal combustion engine is prohibited by the intermittent permission determining module and a load operation is not demanded of the internal combustion engine, the control module controlling the internal combustion engine so as to autonomously operate at a second autonomous rotational speed defined to be not more than the first autonomous rotational speed when the fuel consumption priority mode selection switch is turned on during the intermittent operation prohibition. - View Dependent Claims (13, 14, 15, 16, 17)

18. A control method of a vehicle including an internal combustion engine capable of outputting power for driving and performing an intermittent operation and a fuel consumption priority mode selection switch to select a fuel consumption priority mode that gives priority to fuel consumption, the method comprising the steps of:
-
(a) prohibiting the intermittent operation of internal combustion engine at least one of when a warm up of the internal combustion engine is necessary and when a heating is demanded of a heater that heats a vehicle room through the use of the internal combustion engine as a heat source; and (b) controlling the internal combustion engine so as to autonomously operate at a first autonomous rotational speed when the fuel consumption priority mode selection switch is turned off during an intermittent operation prohibition in which the intermittent operation of the internal combustion engine is prohibited at the step (a) and a load operation is not demanded of the internal combustion engine, the step (b) controlling the internal combustion engine so as to autonomously operate at a second autonomous rotational speed defined to be not more than the first autonomous rotational speed when the fuel consumption priority mode selection switch is turned on during the intermittent operation prohibition.
