Abstract:
A synchromesh-type transmission comprising a gear train for speed-change, a synchromesh mechanism for changing a combination of gears in the gear train, an actuator for actuating the synchromesh mechanism, and a control apparatus for controlling operation of the actuator, said control apparatus including:judging means for judging a shifting of a shifting lever and for detecting an accelerator opened degree;calculating means for calculating a shifting time of the actuator corresponding to the detected accelerator opened degree based on a predetermined map which sets forth a relationship between the accelerator opened degree and the shifting time of the actuator so that as the accelerator opened degree becomes smaller the shifting time becomes longer and so that as the accelerator opened degree becomes larger the shifting time becomes shorter;command means for determining an operating speed of the actuator which will complete a speed-change within the calculated shifting time and for commanding the actuator based on the determined operating speed.
