摘要： The present invention provides an engine starting method from an idling stop condition wherein a preliminary step pushes a pinion to abut with a ring gear when a vehicle operating condition is in an idling stop condition, a starting step rotates the pinion into mesh with the ring gear by a motor upon receiving an engine start signal and thereafter an engine is started, and a restoring step is carried out after engine startup where the pinion is restored to an original position thereof. Also provided, when the engine is stopped, a pinion is meshed with a ring gear. Upon engine start-up, a pinion actuator disengages the pinion from the ring gear and a cutout portion engages an engaging piece to maintain the pinion disengaged. When the engine stops, a releasing actuator disengages the cutout portion and the engaging piece and the pinion is reset.

摘要： A starter control system is comprised of a starter motor, a control circuit for controlling the starter motor to rotate at a preliminary rotation speed that is high enough to engage a pinion with an engine for a predetermined time and low enough to suppress a harsh noise caused when the pinion engages the engine and, thereafter, at a normal rotation speed that is high enough to start the engine, and a control circuit for changing the preliminary rotation speed according to an engine temperature. The starter control system is effective to reduce noises that are caused when the engine is started by an economy-run system.

摘要： In the case of an engine automatic stop and start system in which an engine is stopped while a vehicle is stopped and the engine is started when the vehicle is started, it is necessary to shorten an engine starting time when a driver desires to move the vehicle. Further, it is desirable to efficiently compensate the electric power consumed by the starter. The vehicle contains an existing low voltage power source and a high voltage power source with an excellent charging efficiency. When the engine switches from a running condition to a stopped condition while the vehicle is stopped, a change-over switch switches and applies the voltage of the high voltage power source to a starter motor. This causes the starter motor to rotate at high speeds, thereby starting the engine very quickly. Therefore, it is possible to reduce overall energy losses and improve vehicle fuel consumption.

摘要： Simplifying a control system by integrating current control for an exciting coil and a main current control for a starter motor is accomplished by a current control unit for a starter motor and is constructed with a control device provided among a battery, a motor contact point and an exciting coil, and a starter ECU for driving the control device. The control device has a device capacity for allowing main current of the starter motor. The starter ECU changes a control specification for the control device before and after closing the motor contact point. That is, control-start timing of a coil current is determined by a battery voltage before closing the motor contact point. Thereafter, the coil current is restricted to a predetermined value to reduce a moving speed of a plunger. After closing the motor contact point, the main current is slowly raised.

摘要： An engine start-stop control system for an automotive vehicle includes a first step for supplying current to a solenoid of a magnet switch of a starter at 100% duty ratio until a first predetermined time passes, a second step for supplying current to the solenoid at a duty ratio that is less than 100% after the first predetermined period passes until a second predetermined period passes, and a third step for supplying current to the solenoid at 100% duty ratio after the second predetermined period passes until a third predetermined period passes. Therefore, a pinion of the starter reaches a ring gear of the engine in a short time and engages the ring gear with a moderate impacting shock, thereby preventing the pinion and the ring gear from being damaged.

摘要： In a current supply circuit for starters, an inductance coil is connected in series or a capacitor is connected in parallel with a starter motor to slow down the rise of a current supplied to the starter motor. The current, which flows in a magnet switch upon occurrence of bouncing of the magnet switch, is lowered. Thus even if the time of occurrence of bouncing delays due to increased inductance of a pull-in coil, the magnet switch turns on and off a small current by bouncing and hence generation of noise arising from bouncing can be suppressed. Generation of arc in the magnet switch due to bouncing can be suppressed, and the reliability of the magnet switch can be increased.

摘要： An electric power supply system for a starter comprises a capacitor. This capacitor is charged by a battery through a charging circuit including resistors that charges the capacitor by dividing a voltage of the battery by the resistors. This capacitor is discharged to the starter through a discharge circuit that applies to the starter a charged voltage of the capacitor in addition to the voltage of the battery. When the starter is driven, the connection of the capacitor is switched from the charging circuit to the discharging circuit by an ECU and switching relays.

摘要： An engine starter system includes a current switching device for controlling an armature current, a shorting relay for electrically shorting the current switching device, and an electronic control circuit. In a normal starting mode, the electronic control circuit gradually increases the armature current by varying a duty ratio of the current switching device. When the armature current becomes larger than an allowable current value of the current switching device, an armature is energized through the shorting relay. In an economy-running starting mode, the armature current is controlled through the current switching device until the engine is completely started.

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.
