DISPOSITIF D'ESTIMATION DE POSITION D'ARRET D'UN MOTEUR A COMBUSTION INTERNE

摘要

The device includes an engine motor-generator (3) having the same function as the electrical motor and generator connected mutually with the crankshaft (46) of the IC engine. There is a first detection unit (3a) for detecting a rotational position of the engine electrical-generator. There is a second detection unit (90,70) for detecting the crankshaft angle of the crankshaft, and an estimating unit for estimating the stop position of the IC engine on the base of the rotational position of the IC engine electrical-generator and the angle of the crankshaft.
