Method and apparatus for controlling gear-shift of motor-driven gear shifter

Abstract

To provide a method and an apparatus for controlling a gear-shift of a motor-driven gear shifter in which the gear-shift is electrically performed by a motor. In particular, the present invention relates to a method and an apparatus for detecting a rotational position of a shift drum, when the shift operation is not normally ended, and thereby a shift drum is in the half-neutral state, which automatically executes the shift operation. In the method for controlling the gear-shift of the motor-driven gear shifter, the motor is driven in a desired shift direction, to intermittently turn a shift drum, thereby shifting one gear stage to another gear stage. The rotational position of the shift drum is monitored, and when the shift drum stays at a rotational position other than a rotational position corresponding to a desired gear stage, the motor is re-driven in the shift direction.
