摘要： An electromagnetic switch is provided which includes: a coil generating magnetomotive force; a frame accommodating the coil and generating a flux path; a resin cover covering an opening of the frame; and a current-supply terminal member energizing the coil. The current-supply terminal member includes: a blade-shaped terminal whose end is connected to the coil and whose another end is drawn out of the resin cover in the axial direction of the electromagnetic switch; and a plate-shaped external connection terminal whose end is joined to an end of the blade-shaped terminal and whose another end is drawn out in the direction intersecting the axial direction. A portion between the ends of the external connection terminal is insert-molded in a terminal anchor block provided with the resin cover. A female terminal of a power supply connector provided at an electric supply line is fitted and electrically connected to the external connection terminal.

摘要： An apparatus for starting an engine, including a motor, an output shaft driven by the motor, a pinion provided along the output shaft, and an electro-magnetic solenoid device. The electro-magnetic solenoid device is configured to push the pinion axially toward a ring gear of the engine to mesh the pinion with the ring gear and transfer a rotational force, which is referred to as a motor torque, generated by energization of the motor from the pinion to the ring gear, thereby starting the engine. The apparatus is configured such that, at starting of the engine in its warmed-up state, the motor torque can continue to be applied from the pinion to the ring gear until at least the second compression stroke even when an engine speed varies.

摘要： An engine starting apparatus includes a starter and a starter control unit configured to control driving of the starter. The starter control unit operates a motor with a pinion engaged with a ring gear to thereby crank an engine, and de-engage the pinion from the ring gear or de-energize the motor to thereby terminate the cranking of the engine. A cranking time from when cranking of the engine is initiated to when a predetermined engine speed equal to or greater than 450 rpm is reached is equal to or less than an acceptable limit of cranking time that does not provide, to a user of a vehicle, noticeable discomfort caused by cranking noise generated during the cranking of the engine.

摘要： An engine start system which may be employed in automotive idle stop systems. To start an engine, the system brings a pinion gear into engagement with a ring gear coupled to the engine and turns on an electric motor to rotate the ring gear through the pinion gear to crank the engine. When it is requested to start the engine during deceleration of the engine before stop thereof, the system thrusts the pinion into engagement with the ring gear and then turns on the motor to rotate the pinion gear, in other words, delays the activation of the motor until after the pinion gear has engaged the ring gear. This minimizes mechanical impact or noise arising from the engagement of the pinion gear with the ring gear and improves the reliability in engagement with the ring gear during the deceleration of the engine and durability of the system.

摘要： In a system for controlling rotation of torque applied to a rotating shaft of an engine of a vehicle that uses the engine as a drive source thereof, a motor is provided. A main controller controls the engine and the motor. The main controller selectably activates the motor that applies first torque to the rotating shaft of the engine, and deactivates the motor. A rotary electric machine includes a rotor connected to the rotating shaft of the engine. A rotation parameter detector measures a rotation parameter associated with rotation of the rotor of the rotary electric machine. A sequence controller performs, in response to an occurrence of a trigger situation, a control sequence that controls, independently of the main controller, the rotary electric machine based on the rotation parameter measured by the rotation parameter detector, thus applying second torque to the rotating shaft of the engine.

摘要： In an engine starting apparatus, a starter control unit is configured to, upon command to start the engine, put a starter in a drive ON state to begin cranking of the engine and then put the starter in a drive OFF state at a predetermined timing. The starter control unit is configured to, when acceleration is requested within a predetermined time period from the command to start the engine, keep the starter in the drive ON state even after the time when the starter would be put in the drive OFF state without the acceleration request within the predetermined time period, and drive the starter to torque-assist the engine, thereby performing an assist mode in which both the engine) and the starter serve as drive sources for driving a vehicle.
