Abstract
In a hybrid vehicle, when an ECO switchis turned off while an intermittent operation of an engineis prohibited in response to a warm-up demand of the engineaccording to a cooling water temperature Tw or a heating demand, the engineis autonomously operated at a target rotational speed Ne* derived and set from a normal autonomous rotational speed setting map (Steps, S). When the ECO switchis turned on while the warm-up is demanded, the engineis 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, S).
