Study on the adaptive fuzzy control for CVT vehicle
无级变速汽车的自适应模糊控制研究

Based on the simple CVT (continuously variable transmission) driveline model, an adaptive fuzzy control system for CVT vehicle was designed to improve the adaptability of the control system for CVT vehicle. The adaptive fuzzy control system consisted of a scaling factor self-tuning fuzzy throttle controller, and a hybrid fuzzy-PID CVT ratio and brake controller. The adaptive fuzzy control strategy is independent of vehicle model, and depends only on the instantaneous vehicle states. So it has good robustness to uncertain vehicle parameters and exogenous load disturbance. The simulation results showed that the proposed adaptive fuzzy system has good adaptability.
