START CONTROL DEVICE FOR ENGINE

摘要

PROBLEM TO BE SOLVED: To prevent overshoot of engine rotation by calculating production of electricity for generating power to a motor generator on the basis of a time from engine start, and controlling power generation on the basis of the production of electricity, after start complete explosion of an engine is detected. SOLUTION: When a brake switch 11 is turned on by stepping down a bake pedal after a vehicle is operated, car speed is nearly 0 km/h, and engine rotational speed detected by a rotational speed sensor 9 is within idling rotational speed, fuel injection of an engine is stopped under control by a start control unit 10, and thereby, the engine is temporarily stopped. When the engine is restarted when the brake pedal is released, a motor generator(MG) 2 is driven, and a count operation of a timer is started. When fuel injection is started, cranking is carried out, and engine rotational speed attains target rotational speed Ni, production of electricity of the MG 2 is set on the basis of a count time, and control is switched to control for generating power of the MG 2.
