摘要： A normally-closed electromagnetic relay which may be used in controlling a supply of electric current to an automotive engine starter. The electromagnetic relay is equipped with a resistor and a shirt circuit. The short circuit is created by closing of relay contacts when a relay coil is energized to establish an electric connection between ends of the resistor to supply the current from a battery to an electric motor without flowing through the resistor and opened by opening of the relay contacts when the relay coil is deenergized to supply the electric current from the battery to the electric motor through the resistor. If a motor drive signal line leading to the electromagnetic relay is disconnected when the relay coil is kept energized, it will cause the short circuit to be established to ensure the supply of current to the motor, which also avoids the melting down of the resistor.

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 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： 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.
