Title:
エンジン始動装置および鞍乗型車両
Document Type and Number:
Japanese Patent JP7284351
Kind Code:
B2
Abstract:
Provided is an engine starting device with which reverse drive in swing-back control can be stopped accurately within a desired range. An engine starting device (100) is provided with an ACG starter motor (50), a crank angle sensor (40) for detecting the state of rotation of a crankshaft (C), a rotational speed calculating means (81) for calculating the rotational speed (Ne) of the crankshaft (C), and a control unit (80) for controlling driving of and electricity generation by the ACG starter motor (50), wherein the control unit (80) executes swing-back control to reverse-drive the crankshaft (C) to within a predetermined range during startup of an engine (E). The control unit (80) reduces the output of the ACG starter motor (50) when the rotational speed (Ne) exceeds a threshold (Ne1) during the swing-back control, and increases the output of the ACG starter motor (50) when the rotational speed (Ne) drops to or below the threshold (Ne1) during the swing-back control.
