The method includes setting, as a first reference position, a motor position at a time point when shift is completed; driving the motor in opposite directions on the basis of the first reference position; measuring a rotation amount of the motor and a driving current flowing through the motor while the motor is driven in opposite directions; and calculating a rotation amount of the motor at a point where the driving current of the motor becomes minimum, and setting, as a second reference position, a position resulting after the motor rotates further by the calculated rotation amount from the first reference position.

Abstract: Rack-and-pinion sliding support mechanisms and mechanical elements thereof. One or more shafts are coupled to pinions configured to engage with one or more racks and configured to be driven by one or more motors. The rack and pinion are configured to provide vertical and horizontal displacement to reduce premature component wear leading to poor gear mesh caused to by forces on the mechanism during use. Motor assembly in such support mechanism is modified—as compared to current industrial versions—to prevent the destruction of motor-assembly housing by torques generated by the one or more motors and transferred to the pinions, thereby reducing motor failures.

Automatic powertrain command systems with the proposed GSMs are also proposed and also vehicles with the proposed automatic powertrain command systems.
