<P>PROBLEM TO BE SOLVED: To appropriately stop operation of an engine according to supply of exhaust gas by an EGR (Exhaust Gas Recirculation) system to an intake system when a request is made to stop the operation of the engine for intermittent operation. <P>SOLUTION: When the request to stop the operation of the engine is made for intermittent operation, annealing coefficient τ is set larger as the EGR valve opening EV is larger (S100). The required power Pe* of the engine is set to gradually decrease using the set annealing coefficient τ (S140). When the required power Pe* is a fuel injection stop power Pstop or larger, the engine and two motors are controlled so that the required power Pe* is output from the engine (S150-S170 and S200-S230). When the required power Pe* becomes less than the fuel injection stop power Pstop, the fuel injection to the engine is stopped, and the engine and two motors are controlled so that the operation of the engine is stopped (S180-S230). <P>COPYRIGHT: (C)2010,JPO&INPIT |
