    摘要： An engine-starting apparatus includes an electric motor and an overrunning clutch that transmits a rotational torque of the electric motor to an internal combustion engine. A coupling speed for re-coupling the clutch for re-cranking the engine while it is still rotating by the inertia is set to a point where an inertial speed of the engine becomes equal to or a little higher than an inertial speed of the electric motor. The electric motor is switched on again when its speed decreases to the coupling speed or lower. In this manner, shocks and noises generated in the re-coupling of the clutch are avoided, and the engine can be smoothly re-cranked while it is still rotating by its inertia.

    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： 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： 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 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.
