초록 ▼

In a system, a starter includes a motor for rotatably driving an output shaft with a pinion and an actuator that shifts the pinion toward a ring gear to be engaged with the ring gear. A monitor unit monitors a rotational speed of the internal combustion engine. The rotational speed of the internal combustion engine drops after an automatic control for stop of the engine. When an engine restart request occurs with the rotational speed being within a preset range during the rotational speed of the internal combustion engine dropping by the automatic control for stop of the engine, a drive unit drives the actuator to shift the pinion toward the ring gear to be engaged with the ring gear. The drive unit rotatably drives the motor with the pinion being engaged with the ring gear to thereby crank the crankshaft.

What is claimed is: 1. An engine automatic stop-and-start control system comprising a starter provided with: a motor for rotatably driving a pinion, a mechanical relay provided between the motor and a battery, an actuator for engaging the pinion with a ring gear coupled to a crankshaft of an engine, and a one-way clutch that does not transfer motive power from the pinion to the motor in a rotating direction of the motor, the engine automatic stop-and-start control system automatically stopping the engine when an engine automatic stop request occurs, the engine automatic stop-and-start control system comprising:a restart control means that, after an engine restart request occurs with a speed of the engine being within a predetermined speed range during an engine speed dropping period in which the speed of the engine drops due to the occurrence of the engine automatic stop request, when a rotational speed of the ring gear is higher than a rotational speed of the pinion and a difference between the rotational speed of the ring gear and the rotational speed of the pinion is equal to or lower than 250 rpm, engages the pinion with the ring gear so that, after the one-way clutch idles, the one-way clutch is locked with a reduction in the rotational speed of the ring gear whereby motive power is transferred from the motor to the pinion, the motive power rotating the pinion to start cranking by the starter to restart the engine.
