Research on Gear Shift Drive Mechanism of Automatic Mechanical Transmission Based on Brushless DC Motor
In order to improve the reliability of automatic mechanical transmission (AMT) system, brushless DC motor was employed as the gear shift actuating mechanism of AMT instead of brush DC motor. Hardware circuitry and software programs of electronic control unit (ECU) were designed. Bench test was conducted and experimental results indicate that the design of gear shift actuating mechanism based on brushless DC motor meets the requirements of practical application and improves the reliability of AMT system.
