PROBLEM TO BE SOLVED: To inhibit intermittent operation of an engine at more proper timing.SOLUTION: When an engine is operated by autonomous operation during stopping, margin temperature &Dgr;Tslft1 obtained by subtracting self-heating temperature Tslft1 from upper limit self-heating temperature Tt1max is added to an initial threshold Tjini for obtaining a temperature threshold Tj. During operation of an engine 22 during stopping when cooling water temperature Tw exceeds the temperature threshold Tj, intermittent operation of the engine 22 is inhibited and the engine 22 is controlled so as to be operated continuously. |
