ABSTRACT:
An apparatus for controlling a gear shift device comprises a gear shift controller that operates the gear shift device from a first gear position to a second gear position during a gear shift operation, a movement sensor that detects movement of the gear shift device, a timer, and a gear shift stopping unit that provides a signal to the gear shift controller to stop the gear shift operation when the timer measures a first time interval during which the movement sensor does not sense movement of the gear shift device.
