摘要

 针对装有湿式双离合器式自动变速器的车辆起步控制问题,根据起步过程的性能评价指标,在综合考虑驾驶员的起步意图、发动机的运行状态及离合器的接合状况的基础上,提出了基于模糊智能控制的湿式双离合器式自动变速器的起步控制策略,确定起步过程中的离合器目标压力,根据离合器目标压力与实际压力值的误差,设计基于FCMAC的离合器压力智能控制系统,实现离合器压力的精确控制.采用该控制方法进行实车起步试验,验证了控制策略的有效性.试验结果表明:离合器压力控制系统保证了离合器压力的精确控制,起步控制策略能够满足汽车起步过程的平顺性和快捷性要求,使车辆具有良好的起步品质.

Abstract

 In order to solve the starting control problems of vehicle equipped with wet dual clutch transmission, the starting strategy based on fuzzy control was proposed with regarding of driver intention, engine running state and clutch engaging state. The fuzzy controller was designed to solve the starting nonlinearities and uncertainties  due to variation of vehicle characteristics, driving condition and driver intention. The wet clutch target pressure of starting phases was determined by the fuzzy controller. Based on fuzzy cerebellar model articulation controller (FCMAC) ,the clutch pressure intelligent control arithmetic was designed to realize accurate control of clutch pressure. The vehicle starting experiment was conducted to verify the control strategy. The results show that the clutch pressure control system ensures precise control of clutch pressure,and starting control strategy meets the requirements of smooth and rapid ride in starting process.The starting quality of vehicle is satisfying according to the proposed control strategy.
