Abstract
A transmission apparatus for a vehicle includes a shift spindle having a clutch actuator, and also includes a shift actuator adapted to operate a shift drum. The apparatus also includes a motor for rotating the shift spindle, and a controller for controlling the motor. In use, the clutch actuator is rotated prior to the shift actuator when the shift spindle is rotated to a shift-down side. The controller rotates the shift spindle to a shift-up side and stores, as a standard duty, a driving duty of the motor at the time when a rotary angle of the shift drum reaches a drum angle threshold. Then, the controller rotates the shift spindle to a shift-down side, and learns a rotary angle of the shift spindle at the time when the standard duty is generated, as a touch point at which the clutch is initially partially engaged.
