    摘要： An engine start system which may be employed in automotive idle stop systems. The engine start system includes a pinion gear to be pushed to a ring gear coupled to an engine for achieving meshing engagement with the ring gear. After the pinion gear engages the ring gear, the engine start system starts to rotate the pinion gear using a starter motor to crank the engine. Specifically, when an engine restart request is made following an engine stop request, the engine start system waits until after the speed of the engine drops below a preselected gear engageable speed and then moves the pinion gear toward the ring gear without rotating the pinion gear. This minimizes the consumption of fuel in the vehicle in supplying electric power to the starter motor and a maximum level of mechanical noise arising from the engagement of the pinion gear with the ring gear.

    摘要： 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.

    摘要： In a system for cranking a crankshaft of an internal combustion engine, a starter is provided with a motor working to, when energized, rotatably drive an output shaft with a pinion and an actuator working to, when energized, shift the pinion toward the ring gear to be engaged with the ring gear. A power supply is electrically connected to the motor and operative to output electrical power. A first mechanical relay is electrically connected between the power supply and the motor, and works to turn on and off a supply of a current based on the electrical power to the motor for rotating the pinion. A switching element is electrically connected across the first mechanical relay, and works to turn on and off the supply of the current to the motor for rotating the pinion.

    摘要： A system is installed in a vehicle having an internal combustion engine, a transmission, and a clutch. The system restarts, according to at least one engine restart condition is met, the internal combustion engine that has been automatically controlled for stop thereof. The system includes a restart-condition determiner configured to determine that, as the at least one engine restart condition, an operation of the clutch is started by a driver of the vehicle for shifting the second state to the first state. The system includes a state detector configured to detect an operated state of the clutch during the clutch is shifted from a disengagement state to an engagement state. The system includes a restart controller configured to determine whether to enable or disable the restart of the internal combustion engine according to the operated state of the clutch detected by the state detector.
