START CONTROL DEVICE OF ENGINE |
摘要 |
PROBLEM TO BE SOLVED: To obtain a sporty start feeling by properly securing both a steep rise of an engine rotation number and a steep drop of the engine rotation number while suppressing the deterioration of fuel economy at a start of an engine.SOLUTION: A start control device (ECU 10) of an engine comprising an alternator 21 for generating power by being driven by an engine 10 comprises: a rotation-number steep rise control part 50a which steeply raises an engine rotation number toward a target rotation number by increasing a suction air amount at a start of the engine; and a power generation control part 50b which performs control for increasing a target current of the alternator 21 so that a power generation current of the alternator 21 reaches a prescribed value or higher when the engine rotation number reaches the target rotation number by control by the rotation-number steep rise control part 50a, or after the engine rotation number reaches the target rotation number.SELECTED DRAWING: Figure 12 |
