This paper intends to predict and analyze the torque of the modern Electromechanical Compound Transmission System (ECTS) as required with current technologies. The analytical method is defined in such a way that the Matlab / Simulink platform constructs a forward simulation model for ECTS. The analysis of the model turns out that the overload of the system battery power has been improved, while the real-time performance and the control effect of the algorithm are demonstrated. It is concluded that the model built on Matlab / Simulink platform can effectively interpret the torques as required for ECTS.
