Abstract
An engine starting device for an automatic idling stop system includes: a crank angle sensor for detecting a crank angle of an engine; a ring gear connected to a crankshaft of the engine, for transmitting rotation of the engine; ring gear rpm detecting section; a starter motor for starting the engine; a pinion gear for transmitting rotation of the starter motor to the ring gear; pinion-gear push-out section for pushing out the pinion gear into meshing engagement with the ring gear; and pinion gear push-out control section for driving the pinion-gear push-out section to bring the pinion gear and the ring gear into meshing engagement when the ring gear rpm detected by the ring gear rotational speed detection section becomes smaller than a threshold value which is determined by at least one of the crank angle, a gear range, and a restart condition.
