Energy and environment has been the problem which is the most concerned by all over the world. Hybrid electric vehicle (HEV), which has the virtue of low exhaustion and low consumption, is the optimal choice to solve these problems at present. As an innovative power-split transmission (PST) technology, electro-mechanical transmission (EMT) is widely applied in military and civilian vehicles. In this paper, the dynamic matching problem of a dual-mode EMT is studied and a dynamic matching model is developed. A multi-objective optimization model is built to improve the motor energy utilization ratio through optimizing the design parameters. Sensitivity of the design parameters for dynamic matching performance are analyzed by design of experiments (DOE). Finally, the feasible region of the optimal parameters where the dynamic matching model get the optimal evaluation index is obtained.
