摘要： A starter includes an electromagnetic solenoid that generates force for pushing a pinion gear 6 to a ring gear side, and an electromagnetic switch that opens and closes a motor contact point. When idle-stop is performed, an ECU energizes a solenoid coil of the electromagnetic solenoid during inertial rotation until the ring gear stops rotating. After rotation of an engine is stopped, the ECU stops energizing the solenoid coil. As a result, in the starter, the pinion gear can mesh with the ring gear that is rotating by inertia without use of the rotational force of a motor. The meshed state can be maintained even after energization of the solenoid coil is stopped.

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, an angle sensor outputs a pulse each time an output shaft of an internal combustion engine rotates by a preset angle, and a calculator calculates speed-change information indicative of a change in a speed of rotation of the output shaft based on the pulses outputted from the angle sensor. A determiner determines, based on the speed-change information, whether at least one of the pulses outputted from the angle sensor represents a proper timing for a preset of a pinion of a starter with a ring gear mounted on the output shaft. A pinion engaging unit shifts the pinion toward the ring gear so that the pinion is engaged with the ring gear when it is determined that the at least one of the pulses outputted from the angle sensor represents the proper timing for the preset of the pinion with the ring gear.

摘要： In a starter for starting an on-vehicle engine, a solenoid is provided to push a pinion gear. The solenoid has an electromagnetic coil composed of a single coil and electrically separated from a motor circuit, a fixed core, and a plunger. Supply of excitation current to the electromagnetic coil allows the fixed core to be magnetized to attract the plunger. Hence, a movement of the plunger results in a push of the movable member toward the ring gear. A switch is provided in the circuit and has a contact, a movable core, and a switch coil functioning as an electromagnet attracting the movable core in response to supply of current to the switch coil. A movement of the movable core results in on/off switching operations of the switch. The switch is allowed to operate independently of the solenoid when both the switch and solenoid are controlled.

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 engageble 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 an engine starting apparatus, together with a one-way clutch, a pinion is pushed toward a ring gear of an engine mounted in a vehicle. The one-way clutch has an idling torque smaller than a torque of the ring gear that tries to turn the pinion when the pinion is pushed to the ring gear. By a control device, a pinion pushing device is enabled to operate when i) the revolution speed of the ring gear is larger than a revolution speed of the pinion and ii) a relative revolution speed between the revolution speed of the ring gear and the revolution speed of the pinion is a desired value.
