On the basis of the analysis of the belt misalignment of the metal V - belt CVT, the reason of the belt misalignment is discussed. In order to control the misalignment, an electro - hydraulic control system is designed. After analyzing the structure and principle of the electro - hydraulic control system, the mathematical model of the electrohydraulic control system is established. Being varieties of the working situation of car and the non - linearity of the electro - hydraulic control system, a fuzzy PID algorithm is adopted. Then the performance simulation of the electro - hydraulic control system is conducted. The simulation results showe that the electro - hydraulic control system and the fuzzy controller with parameter self adjustment could not only control ratio, which has a higher accuracy of the stable state and a stronger robust of the driving condition, but also eliminate the belt misalignment.
