N2 - In this paper, a mode control strategy for a two-mode EVT hybrid electric vehicle (HEV) is proposed,considering transmission efficiency and mode change quality. First,speed and torque characteristics are analyzed by establishing relevant equations of two transmission mode. Next,the optimal operation mode is selected from the viewpoint of the transmission efficiency,when it is higher at a given speed ratio.Then,two scheme of operation sequence of clutch/brake are compared,and a control algorithm of synchronous control of two MGs and engine is suggested to reduce speed difference between both end of the clutch and torque fluctuation. A vehicle simulation based on Matlab/Simulink was performed to testify the mode change control algorithm of the dual-mode EVT HEV,and the simulation results showed that the mode control strategy for the dual-mode EVT HEV gave acceptable performance.
