    摘要: The present invention provides a VCM driver realizing low power consumption and high accuracy and a PWM amplifier compensating a dead time distortion. A phase compensator, a ΔS modulator receiving an output signal of the phase compensator and converting the output signal to a control code of predetermined bits, a PWM modulator receiving the control code to produce a PWM signal, and an output circuit receiving the PWM signal to drive a voice coil constitute a forward path. A sense amplifier sensing a current of the voice coil, an ADC receiving an output signal of the sense amplifier, a low-pass filter receiving an output signal of the ADC, and a decimation filter receiving an output signal of the low-pass filter constitute a feedback path. An output signal of the decimation filter is fed back to the input side of the phase compensator to form a major feedback loop having a first-order characteristic loop gain. An output signal of the decimation filter is fed back to the output side of the phase compensator to form a minor feedback loop having a loop gain which is flat until a target band frequency when viewed from the output side of the phase compensator.

    摘要: To provide a small-sized and lightweight gearshift operating device that is capable of performing a gearshift operation in a short time at low power consumption, a guide slit having a plurality of slits 41 parallel with the shift fork shafts and a plurality of slant slits 42 concentrated to a neutral point 43 from them is employed to guide a follower 33. The follower 33 is operated along the guide slit, thus the number of times of starting and stopping operations of the motor for the shift operation is reduced, and the load of the actuator for the selection operation is reduced.

    摘要: In a shift system wherein the transfer of power is performed using a motor, the smaller the gear ratio difference is, the smaller can be made the motor output. However, the number of gears must be increased in order to reduce the gear ratio. As the number of gears increases, the problem of gear noise becomes more serious. It is necessary to prevent both an increase in the number of gears and an increase of the motor output. In a vehicular drive system according to the present invention, a shifting power unit is not merely provided between a first intermediate shaft and a second intermediate shaft of a shift system which has the two intermediate shafts, but one side of a shifting power unit is connected to a vehicle driving power unit, while an opposite side thereof is connected to a power transfer switching clutch so as to be connected to the first or the second intermediate shaft through a reduction mechanism, whereby the output of the shifting power unit is decreased while minimizing an increase in the number of gears.

    摘要: A control unit and a control method of an automatic transmission can accurately estimate an output shaft torque in a torque converter with little error. The control unit of the automatic transmission estimates an output shaft torque in a torque converter with using a characteristic of the torque converter and controls the automatic transmission by using the estimated torque converter output shaft torque. At lest one of a pump capacity characteristic and a torque ration characteristic of the torque converter is corrected in the control unit by using an oil temperature of the automatic transmission and at least one of parameters expressing an operating state, thereby estimating the torque converter output shaft torque.
