  • Patent number: 4911031
    Abstract: An apparatus for controlling a transmission includes a detecting device for detecting the speed of rotation of an electric motor of a selecting actuator and a learning device for learning angular positions of the motor which correspond respectively to gear selecting positions based on a detected signal from the detecting device. Gear selecting operation of the selecting actuator is controlled by the learned angular positions of the motor.

  • Patent number: 4856360
    Abstract: 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.

  • Patent number: 4590906
    Abstract: The invention is an internal combustion engine fuel control apparatus including a movable member for controlling the supply of fuel to the engine, the member being movable in one sense to increase fuel flow and movable in an opposite sense to decrease fuel flow; a control mechanism producing a variable level output for controlling the engine; an operator controlling movement of the movable member in response to the level of the output; an initiator coupled to the movable member and the operator and operative to initiate control of the movable member by the operator at a given level of the output; an adjustment means for adjusting the given level of the output; a bias element biasing the movable member in the opposite sense; and an idle set means for establishing an adjustable mechanism degree of movement of the movable member in the opposite direction.
