摘要: 介绍了当下汽车产业状况,分析了基于规则 PID 的控制策略和单纯性模糊控制策略的燃油经济性,结果显示,其在仿真循环的某些车辆特需工况 (如急加速、紧急制动等),燃油经济性不能满足节能减排需求。因此,研究设计了一种基于模糊 PID 的控制策略,应用于液压混合动力汽车,仿真验证表明:在模糊 PID 控制策略下,汽车发动机扭矩工作点分布等重要燃油经济性指标,符合验证要求,是一种有效控制策略。

关键词: 液压混合动力;模糊 PID 控制策略, 仿真验证;燃油经济性

Abstract: The current situation of the automobile industry was introduced in this paper. The fuel econormy were analyzed based on the control strategy and the simple fuzzy control strategy of PID. It is foundthat it fails to meet the requirements of energy conservation and emission reduction in some special vehicleconditions ( such as rapid acceleration, emergency braking etc.) of the simulation cycle. The controstrategy based on Fuzzy PID was researched in this paper, which was applied to the Hydraulic Hybrid Vehicle. The simulation results showed: the Fuzzy PID met the verification requirements, the important fueleconomy indexes, such as the distribution of the torque working point of the automobile engine. It isproved to be an effective control strategy under the Fuzzy PID control strategy.

Key words: Hydraulic Hybrid Vehicles, fuzzy PID, simulation verification, fuel economy
