    摘要: An apparatus for driving an electromagnetic load by applying a high voltage at the initial driving stage and thereafter applying a constant hold current is provided with a switch for supplying high-voltage energy to the electromagnetic load from a capacitor for storing high-voltage energy and a control circuit responsive to an electric signal for starting electromagnetic load driving and the output voltage of the capacitor. The control circuit turns the switch on at application of the electric signal and keeps it on until the output voltage reaches a prescribed level. The apparatus of this configuration enables optimum timing of changeover from high-voltage application mode operation to hold mold operation with simple circuitry.

    摘要: A clutch control apparatus for controlling the operation of a friction type clutch comprises a data generator responsive to an engaging command signal for generating an electric signal corresponding to the time-course in a target clutch stroke pattern for engaging the clutch. The actual clutch stroke of the clutch is adjusted by the use of a clutch actuator coupled with the clutch in response to the electric signal in such a way that the actual clutch stroke is made to coincide with the target clutch stroke at each instant, whereby the actual clutch stroke varies in accordance with the desired time-course pattern for engaging the clutch after the application of the engaging command signal. The initial target clutch stroke of the desired pattern may be corrected in accordance with the amount of operation of an acceleration member to reduce the dead time in the torque transmission through the clutch.

    摘要: A solenoid driving apparatus includes at least two solenoids of which driving periods do not overlap, a driving unit for driving each solenoid, and a signal generating unit for giving the driving unit a control signal information of each solenoid. The driving unit includes circuit sections jointly used with regard to the driving of each solenoid, and drives each solenoid based on the control signal information corresponding to each solenoid. The signal generating unit generates the control signal information of each solenoid which is given to the driving unit based on the drive pulse signal corresponding to each solenoid. Also, while a control signal information is given to the driving unit based on the drive pulse signal corresponding to one solenoid, the signal generating unit does not accept the input of any drive pulse signal even when a drive pulse corresponding to the other solenoid is generated by a noise. Thereby, malfunctions and adverse effects on the driving apparatus due to the simultaneous use of common circuit sections of the driving unit for driving more than one solenoid can be prevented.

    摘要: In order to obtain an amount of fuel injection determined by a target fuel injection amount determining unit (51) from an injector (32) supplied with high-pressure fuel from a high-pressure pump (2), there is provided a reference injection period determining unit (52) responsive to a target fuel amount signal (Qt) for determining a reference injection period (Tr) and a correction amount calculating unit (53) responsive to the reference injection period (Tr) and the rotational speed (R) of a high-pressure pump (2) for calculating a correction amount (F) for correcting the error caused by decrease in fuel pressure during the period of fuel injection, whereby an actual injection period (Ta) is determined by correcting the reference injection period (Tr) by the correction value (F). As a result, the injection pulse width can be controlled so as to precisely supply the desired amount of fuel from the injector (32).
