An engine starter includes a starter motor which has an armature, a series-wound field coil and a parallel-wound field coil and a short-circuiting unit for short-circuiting the series-wound field coil under a predetermined engine starting condition. The series-wound field coil has a suitable current limiting resistance. The short-circuiting unit short-circuits the series-wound field coil after a crankshaft of an engine passes a first top dead center of an engine.

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.

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.

An apparatus having electric wheels comprises a pair of left and right wheels, rotary electric machines, i.e. motors, for individually driving these wheels, and a control unit for operating the motors. The motors each have a rotation axis offset from that of the wheel, drive the same one wheel of the pair, and are arranged at positions distanced in the radial direction of the axle by the same length, and on the same plane normal to the axial direction of the axle, being apart from each other in the circumferential direction of the axle with a predetermined angle therebetween. In a preferred mode, power is transmitted from the motors to a single wheel through a belt-type transmission mechanism incorporated in the wheel. Responsive and fine driving power control can be performed without sacrificing the cabin space, thereby providing a vehicle having excellent responsiveness, degree of freedom and reliability.

An automotive power supply system which has two storage batteries mounted in a vehicle which are charged by the electrical energy produced by an electric generator driven by an engine of the vehicle. The system includes a switching device which works to switch between electric connections of the generator to the batteries as functions of predetermined parameters, thereby ensuring the stability in charging and keeping the batteries within a desired serviceable capacity range.

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.

An Electroluminescent display device is designed not to display residual images due to electric charges stored in electroluminescent pixels or to make them invisible, when the device is turned on again. The stored charges are eliminated at the time a normal display on the panel is turned off at an end of an operation, by scanning pixels at least one time while giving a non-activating data voltage thereto. Alternatively, upon turning on the panel, pixels which were activated in a previous use are all lit at least one time, thereby making the residual images invisible. Thus, the residual images stored in a previous operation are not shown or made invisible when the electroluminescent display device is turned on next time.
