摘要:
An in-vehicle generator is caused to start regenerative generation when the regenerative generation is possible. This regenerative generation can decrease a generation amount under a vehicle traveling state where fuel is consumed and exhaust gas is emitted, thereby decreasing a load of an engine and amounts of fuel consumption and exhaust emission. The fuel consumption or exhaust emission to be decreased is computed and transmitted to a managing center via an in-vehicle wireless terminal. The managing center provides a driver with a reward such as a service corresponding to the decreased amount of fuel consumption or exhaust emission that is computed in the relevant vehicle. This system enables the regenerative generation to be returned to the driver as an economic value, motivating the driver to decrease the fuel consumption or exhaust emission. This thereby contributes to the conservation of global environment.

In an alternator, failure in a power supply line connected to an output terminal of a rectifier is detected. Upon detection of a failure in this power supply line, power generation is suppressed for a predetermined period that is longer than the time constant of a field winding of the alternator. Preferably, a high voltage pulse is detected to discriminate a first condition where a single high voltage pulse is generated when an electrical load connected to the power supply line is cut off and a second condition where a high voltage pulse is repeatedly and frequently generated when a failure occurs in the power supply line. Only when the second condition is discriminated, power generation suppression control of the alternator is conducted.
摘要:
A controller for an alternator driven by an output torque of an automotive engine mechanically through a belt is provided. The controller works to control an exciting current supplied to a field winding of the alternator so as to cancel a change in inertia torque of a rotor of the alternator arising from a change in speed of the engine, thereby minimizing a change in tension of the belt.

Magnetic bodies for reducing electromagnetic wave noises are mounted to a battery voltage supplying terminal for supplying of an electric source power for the operation of circuits to an IC chip of a regulator or an internal electric source line for connection of the terminal to the regulator chip. The magnetic bodies are attached to an IG ON terminal for inputting into the regulator chip a voltage signal caused by opening and closing of an ignition switch or to an IG ON detection line for connection of the terminal to the regulator chip. A bypass capacitor is connected to a battery voltage detecting terminal for inputting a change of battery voltage into the regulator chip, or to an internal battery voltage detection line for connection of the terminal to a switching transistor control circuit unit.

A generator control system of a vehicle AC generator includes a field coil, a first polyphase armature winding, a second polyphase armature winding, a first rectifier connected to the first armature winding and a second rectifier connected to the second armature winding. The generation control system includes a power transistor connected with the field coil, a voltage regulator for controlling the power transistor, a voltage comparator for providing a pulse signal by comparing output voltage of one of phase-windings of the first armature winding with one of second phase-windings of the second armature winding and a counter circuit for driving the voltage regulator when the number of pulses of the pulse signal becomes larger than a predetermined value.
摘要:
An electrically operated parking brake apparatus that includes a ball screw mechanism driven by an electric motor so as to move a nut member along a screw-threaded shaft. Two Bowden cables, for example, are connected to left and right ends of an equalizer supported on the nut member via an upper support shaft and a lower support shaft for transmitting brake operation force to wheel brakes. Since an axis of the upper and lower support shafts provided at positions facing each other across the screw-threaded shaft for swingably supporting the equalizer on the nut member passes through the center of the screw-threaded shaft, and a line connecting portion where the pair of Bowden cables are connected to the equalizer passes through the center of the screw-threaded shaft, the application of an unbalanced load to the screw-threaded shaft is prevented.

The invention provides ink which is best suited for inkjet printing of a printed substrate. The ink is a photo polymerizing type water-base ink including at least a colorant, a photo polymerization resin, a photo initiator, and a water-base solvent. The photo polymerization resin includes oligomer particles in an emulsion state and monomers which reside in the oligomer particles. The water-base ink contains, with content ratio in terms of the percentage weight, 5% of ethyleneglycol, and between 0.1% to 10% of 2-pyrrolidone and N-acryloyl morpholine combined.
摘要:
A vehicle alternator control device has a power transistor, a flywheel diode, a voltage control circuit, a primary power supply circuit, and a secondary power supply circuit. When the alternator starts rotation, the secondary power supply circuit drives the primary power supply circuit when the alternator speed reaches a frequency equivalent to a speed higher than an engine idling speed. When the engine stops and the speed of the alternator drops, the secondary power supply circuit stops the primary power supply circuit when the alternator speed reaches a frequency equivalent to a speed below the engine idling speed.
摘要:
Shift means shifts a rotation speed range to a low rotation speed side based on an electricity amount related to rotation speed. In the rotation speed range, driving torque of a generator is suddenly changes as a result of an increase of duty ratio of a switch due to a shortage of generation capacity caused by a reduction of a rotation speed of a vehicle alternator. Preferably, the shift means shifts the rotation speed range to the low rotation speed side by changing the adjust voltage based on the electricity amount related to rotation speed while the rotation speed is reduced.
