摘要

After analyzing the shifting process and the shifting shock of automated transmission, the shifting process is divided as following five phases: unload, back gear, synchronization, in-gear, and load. The shifting quality is optimized by controlling the electric motor and gearbox in a coordinated way. In addition, the models of automated shift, coordination controller (including logical control model of the above phases), electric motor, vehicle dynamic, and shock extent are established based on MATLAB/Simulink. The simulation results show that taking coordination control can decrease shifting shock extent and optimize shifting quality.
