摘要

摘要: 在传统的最佳经济性、动力性换挡规律的基础上,考虑到公交车实际行驶时载荷变化大及驾驶员的操作方便性等因素,利用模糊控制理论,引入了"综合系数",提出了基于公交车质量和油门开度的综合性换挡理论。应用Matlab/Simulink建立了换挡规律模型并进行了仿真,仿真结果表明:提出的综合性换挡理论能够根据驾驶员的意愿以及车辆实际的载客量,自动地调节换挡点。在满足公交车动力要求的前提下,尽量减少其燃油消耗,兼顾了经济性和动力性,同时又方便了驾驶员的操作。

Abstract: Considering the wide variation range of load when it is running and the convenience of operation for the driver, the coefficient of colligation for the driver was introduced, and a comprehensive shift schedule with the parameters of weight and throttle was proposed based on the traditional dynamic and economic shifting schedules by using Fuzzy control theory. Based on the software of Matlab /Simulink, the comprehensive shift schedule structure was designed and simulated. The simulation results show that the shift point can be regulated automatically by using the comprehensive shift schedules based on the willingness and the actual load. On the premise of meeting the power requirement, the fuel consumption should be minimization, meanwhile it is more convenient to drive in considering the dynamic and fuel economy.
