<P>PROBLEM TO BE SOLVED: To execute prescribed abnormality detection to be made with operation of an internal combustion engine, at proper frequency. <P>SOLUTION: When required power Pe* of the engine is a threshold value Pstop2 being smaller than a threshold value Pstop1 (S200, S210) or more, even if the required power Pe* of the engine is less than the threshold value Pstop1 for normally performing an operation stop of the engine (S130) during the operation of the engine when the prescribed abnormality detection performed with the operation of the engine such as abnormality detection of various sensors, or a fuel system or an ignition system of the engine is not completed ( when an abnormality detection completion flag F is a value 0), the engine is self-operated, and the operation is continued (S280). When the required power Pe* is a threshold value Pstart2 or more, the threshold value Pstart2 being smaller than a threshold value Pstart1 for normally starting up the engine, when the engine is not operated, the engine is started. As a result, the execution of the prescribed abnormality detection is secured. <P>COPYRIGHT: (C)2009,JPO&INPIT |
