The Control System Development of Electronic Mechanical Continuous Variable Transmission

Abstract

The electronic mechanical continuous variable transmission (EMCVT) was a metal-belt type continuously variable transmission of new structure. Based on the mechanical structure of EMCVT, the mathematic model of both the matching clutch and speed regulating system was established, while the control requirements were analyzed and hardware circuit was designed. According to the simulation experiment, bench test and loading test with hardware equipment, the control system designed achieved a desired control expectation being stable and robustness, which verifies the correctness of theoretical analysis.
