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.
Claims3
An apparatus for controlling a transmission having a plurality of shifting blocks mounted respectively on a plurality of shifting rods, said apparatus comprising:
- a selecting actuator including an electric motor for moving an internal lever engageable with the shifting blocks in a selecting direction to select gears of the transmission,
- a shifting actuator for moving said internal lever in a shifting direction to shift the gears of the transmission;
- detecting means for detecting the speed of rotation of said motor;
- learning means for learning angular positions of said motor corresponding respectively to gear selecting positions of said internal lever, based on a detected signal from said detecting means;
- means for storing the learned angular positions of said motor;
- and
- means for controlling said motor based on said stored learned angular positions when said selecting actuator is operated.
