    摘要： The hydraulic control device includes a hydraulic fluid temperature estimation means for estimating the temperature of the hydraulic fluid supplied to the hydraulic clutch (actuator). The hydraulic fluid temperature estimation means calculates an output of logistic regression from an integrated value of driving currents and an average value of driving voltage of the electric motor. If the calculated output of the logistic regression is equal to or more than a first threshold value, the hydraulic fluid estimation means calculates a posteriori probability from such output. If the calculated posteriori probability is equal to or more than the second threshold larger than the first threshold value, the hydraulic fluid temperature estimation means determines the posteriori probability to be a final determination result, thereby determining the temperature of the hydraulic fluid to be a predetermined temperature.

    摘要： A half-open position holding apparatus for a vehicle opening and closing member includes an opening and closing member supported in a vehicle body to be openable and closable and has an opening and closing member driving unit that has a motor and a electromagnetic clutch that can put a power transmission path connecting the motor and the opening and closing member in a connected state and in a disconnected state, for driving the opening and closing member in opening and closing directions thereof, and an in-vehicle battery serving as a power source for the electromagnetic clutch. The apparatus includes a controller for controlling the opening and closing member driving unit, that, when the opening and closing member is held at a half-open position between a fully-closed position and a fully-opened position, holds the opening and closing member at the half-open position by stopping the motor, putting the electromagnetic clutch in a connected state, and controlling the electromagnetic clutch to a half-open position holding connection state such that a voltage applied to the electromagnetic clutch becomes a predetermined voltage lower than an output voltage of the in-vehicle battery.

    摘要： A clutch-actuating device for a clutch in a motor vehicle power train has an actuator motor driving an actuating member and a transfer mechanism which transmits the movement of the actuating member to a clutch release element that is movable against an opposing force of a clutch spring to displace the clutch from a closed position to an open position. The transfer mechanism has a first movement range in which the movement of the actuating member in the opening direction of the clutch does not displace the clutch from its closed position, and a second movement range in which the movement of the actuating member causes a displacement of the clutch. The transfer mechanism has an interval of loose play, which is used up within the first range.

    摘要： Pulse frequency modulation is used to control brakes and clutches which are operated by fluid pressure actuators controlled by electrically actuated solenoid valves. Short pulse periods for all duty cycles are generated by feedback from the solenoid valve or from the actuator. In one circuit an electrical control triggers a flip-flop which starts solenoid current. Solenoid movement results in back-emf and its effects on the solenoid flux field or current is detected and used as a feedback signal to reset the flip-flop to thereby turn off the current as soon as the valve is operated. In another circuit, a computer control emits a command for a certain pulse period. Actuator pressure or position is monitored to produce a feedback signal to the computer. If the signal is not received, the pulse period is increased for the next pulse command so that a sufficient pulse period will be found. If the magnitude of the actuator response exceeds a threshold, the pulse period is decreased for the next pulse command. Pulse width modulation may also be improved by the same technique for minimizing the pulse period at the lowest duty cycles and yet assuring actuation.
