Abstract
The driving system layout of 3-gear electric buses was analyzed. The mechanism of the automated manual transmission (AMT) was developed and the transmission control unit (TCU) was built. By modeling and simulating of the main driving motor
the shift control strategies for the main driving motor were established; The shift process data in the AMT system during the road test were collected via the data-saving system
and analyzed statistically afterwards. The data show that the statistical average shift time is 1.86s and the jerk values are between ±35 m/s

which conforms to relating jerk standards. Test results validate the feasibility of the AMT system.
