Method of controlling an automated mechanical transmission shift mechanism.

摘要

For use with an automated mechanical transmission system including an electrically actuated shift mechanism (12) having a motor (70, 72), a method of controlling the shift mechanism is provided for shifting the transmission (10) 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 (100) to minimize power consumption and avoid overheating the motor, and then with a high effective voltage signal (106) upon detection of motor motion (104), to quickly shift the transmission (10) out of gear. <IMAGE>
