<P>PROBLEM TO BE SOLVED: To more properly cope with the lowering of power outputted from an internal combustion engine. <P>SOLUTION: When an engine is operated and an engine demand power Pe* becomes lower than an engine stop determination value Pstp, the operation of the engine is stopped (S330 to S370). When the operation of the engine is stopped and the engine demand power Pe* becomes higher than an engine start determination value Pstrt, the engine is started (S250 to S310). Since the engine stop determination value Pstp and the engine start determination value Pstrt are set to smaller values than those at a normal time when using regular fuel, the engine easily becomes an operated state than the normal time. When using the regular fuel, a corrected rotational number ΔN is added to a target rotational number Ne* of the engine (S260 and S270). As a result, lowering of power outputted from the internal combustion engine can be more properly coped. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
