<P>PROBLEM TO BE SOLVED: To suppress overheating of a cleaning catalyst for cleaning the exhaust of an internal combustion engine when accelerator opening is changed from a state wherein it is less than prescribed opening to a state wherein it is equal to or more than the prescribed openings, and an EGR as recirculation of the exhaust to the intake system of exhaust according is stopped. <P>SOLUTION: When accelerator opening is changed from a state wherein it is less than a prescribed opening to a state wherein it is equal to or more than the prescribed opening, an engine is operated according to an EGR by using a fuel economy priority time operation line until a request power P2 is output from an engine (point A to point B), and after the request power P2 is output from the engine, a state in which the request power P2 is output from the engine is held until the engine is operated on a high torque request time operation line, and the engine speed Ne and engine torque Te are changed to a high torque request time operation line (point B to point C). <P>COPYRIGHT: (C)2011,JPO&INPIT |
