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.
Claims6
An apparatus for controlling a transmission having a synchromesh, comprising:
- a shifting actuator having an electric motor for shifting gears of the transmission;
- means for detecting a shifting stroke of said shifting actuator when said shifting actuator shifts the gears;
- means for measuring a load on the synchromesh when said shifting actuator shifts the gears;
- means for learning a shifting stroke value of said shifting actuator when synchromesh operation of the synchromesh is finished, based on the measured load on the synchromesh;
- means for storing the learned shifting stroke value;
- and
- means for controlling the electric motor of said shifting actuator when shifting the gears, based on the stored shifting stroke value.
