ABSTRACT:
For use with an automated mechanical transmission system including an electrically actuated shift mechanism having a motor, a method of controlling the shift mechanism is provided for shifting the transmission out of gear during a reduced torque shift window by quickly detecting motor motion. The shift mechanism is first energized with a low effective voltage signal to minimize power consumption and avoid overheating the motor, and then with a high effective voltage signal upon detection of motor motion, to quickly shift the transmission out of gear.
