Nowadays, the variable speed function of metal belt CVT assemblied on vehicle is completely based on hydraulic system which is driven by the engine. The extra energy consumption is obvious and the reliability is low during the speed-change process of system because of low efficiency of hydraulic components such as pump and valve. In this paper, Electronic-Mechanical CVT (EMCVT) that is a new kind of metal belt CVT is proposed, which uses DC motor driving system to implement the variable speed function. The model of speed ratio control and the clamping force of cone-plates control is established and the PID algorithm of speed ratio control is presented while the transmission principle and mechanical structure of EMCVT is introduced through the study of artificial characteristic of DC motor and dynamics of the system.
