Abstract：By analyzing the basic working principle, an internal combustion engine (ICE) optimal efficiency control strategy of electrical variable transmission in hybrid electrical vehicle which mainly concerns the inner rotor torque control to and outer rotor speed control to satisfy the efficiency and load demands based on the low level control systems by following the commands of the host computer is given in this paper. The torque identification method is discussed and given in this paper. Furthermore, the corporation relationship of the lower level control systems and the host computer of the vehicle is discussed in the paper. By experiment, the feasibility of the control system and its control strategy is tested and verified.
