AUTOMATIC ENGINE STOPPING/STARTING DEVICE AND AUTOMATIC ENGINE STOPPING/STARTING CONTROL METHOD

摘要

Useless power consumption and sound noise during automatic engine stopping and starting can be suppressed, and automatic start can be speeded up and engagement property can be improved. An automatic engine stopping/starting device comprises: a starter motor (14); a ring gear (12); a pinion gear moving means (17); and a starter control means (11) for, while an engine inertially rotates upon satisfaction of an automatic stop condition, executing an engagement control on the basis of the number of rotations of the engine and for executing an engine restart control for restarting the engine upon satisfaction of a restart condition. In the engagement control by the starter control means, the application of current to the pinion gear moving means is stopped at least simultaneously when or before the rotation of the engine stops.
