An engine starter system for driving an engine starter with electric power from a battery mounted on a motor vehicle has a boost controller for boosting electric power from the battery and a large-capacitance capacitor which is charged by the electric power which is boosted by the boost controller. The engine starter is driven by the electric energy which is stored in the capacitor at a voltage higher than the voltage of the battery.

Driving apparatus for starting an engine with a starter motor energized

An engine starter system for driving an engine starter with electric power from a battery mounted on a motor vehicle has a pair of large-capacitance capacitors which are selectively connected to the battery and the starter. One of the capacitors is connected to the battery and charged thereby when the detected voltage across the one capacitor is lower than a predetermined voltage, and the other capacitor which is charged sufficiently enough is connected to the starter. Electric energy whose voltage is higher than the predetermined voltage is therefore continuously supplied to the starter to start the engine.

Driving apparatus for starting an engine with a starting motor energized

An engine starter system includes a switching-over circuit arrangement for selectively connecting a large-capacity capacitor parallel or in series to a battery. Normally, the capacitor is connected parallel to the battery and charged thereby. When starting an engine with a starter, the charged capacitor is connected in series to the battery, and the voltage of the capacitor and the voltage of the battery are added and applied to the starter to energize a starter motor for starting the engine.

An engine starter system starts a motor in response to operation of a starter keyswitch. Immediately before the engine is started, a capacitor is manually connected to a power supply such as a storage battery. When the capacitor is charged up to a preset voltage, the electric energy stored in the capacitor is discharged to energize the motor.

A power supply device for use on a motor vehicle includes a charging power supply such as an alternator or a battery, a plurality of capacitors, chargeable by the charging power supply, for supplying stored electric energy to an electric load such as an engine starter, and a successive charging control circuit arrangement for successively charging the capacitors, one by one, with the charging power supply.

A method of controlling a traction of a vehicle, comprising the steps of reading a value determining a throttle opening and closing speed from a first throttle control map from which said throttle opening and closing speed are determined on the basis of a difference in speed between a driving and non-driving wheel speeds and of an acceleration of the driving wheel, and converting said value to an actual throttle opening and closing speed with a conversion rate corresponding to an acceleration of the non-driving wheel thereby controlling the throttle of the vehicle.

Traction control method and apparatus for a vehicle

An electric double layer capacitor employs a paste electrode between collector electrodes. The paste electrode is compressed under small load because the collector electrodes are pressed by compression plates in only an area corresponding to the past electrode. With the paste electrode thus compressed, the internal resistance of the capacitance is reduced and the capacitance of the capacitor is stable. The electric double layer capacitor comprises a stack of basic cells of capacitor elements. The basic cells are held closely together by a bolt which extends through central holes in the basic cells and interconnects the compression plates, so that the basic cells are compressed under a uniform and appropriate pressure.

In a traction control system for motor vehicles, a lower limit for throttle opening degree command with respect to each gear position of transmission is set up, and when the transmission is shifted up, the throttle opening degree command is decreased down to the lower limit for throttle opening degree command corresponding to the gear position assumed through the shift-up operation.

An engine preheating system preheats an engine such as a diesel engine efficiently and quickly with heating members such as self-temperature-controlling glow plugs. When the engine is to be preheated quickly, a voltage to be applied to the heating members is increased by electric energy stored in a capacitor capacitors, and a large current is supplied to the heating members to preheat the engine in a short period of time.

A motor vehicle power supply device includes an alternator drivable by an engine mounted on a motor vehicle, a battery chargeable by electric energy generated by the alternator, a capacitor connected to the alternator and the battery, and a charging speed varying circuit arrangement connected between the capacitor, and the alternator and the battery, for varying the speed at which the capacitor is charged. The charging speed varying circuit arrangement is controlled to vary the speed at which the capacitor is charged, depending on the operating condition of the motor vehicle.

Motor vehicle power supply device

An apparatus for controlling a transmission having a synchromesh has a shifting actuator having an electric motor for shifting gears of the transmission. A load on the synchromesh is measured when shifting the gears of the transmission. A shifting stroke value for the shifting actuator when the measured load on the the synchromesh falls within a predetermined range is learned and stored. Based on the stored shifting stroke value, the electric motor of the shifting actuator is controlled when shfting the transmission gears.
