<p>PROBLEM TO BE SOLVED: To warm up catalyst for purifying exhaust gas without deteriorating fuel consumption. SOLUTION: When the warm-up of catalyst is required, a map M2 for warm-up demand is used as a charge and discharge correction value calculation map for deriving a charge and discharge correction value spchg from a battery 194, and accordingly, a demand power for an engine is set to be higher than a normal power. Thus, when the catalyst is warmed up, a power higher than the normal power can be taken out from the engine, and the volume of exhaust gas from the engine can be appropriately ensured thereby it is possible to optimumly warm up the catalyst. Further, even though a higher power is taken out from the engine, the power is converted into an electric power by a generator so as to sufficiently charge the battery, thereby it is possible to prevent the fuel consumption from being deteriorated.</p> |
