摘　　要：基于热泵技术,设计了一种充分利用电机余热的集成式热管理系统,采用换热器将各独立回路联系起来,实现能量的高效利用。针对热管理系统控制难度大的问题,提出了抗饱和积分模糊控制以及多级模糊控制两种优化型模糊控制。基于AMESim搭建了集成式热管理系统模型,并建立了工作模式切换及各关键部件的Simulink控制策略模型,对整车的热管理控制效果进行联合仿真分析。仿真结果表明,在0℃下,集成式热管理系统与各回路相互独立的热管理系统相比驾驶室加热时间缩短约27.8%,能效比平均提升约31.3%,冬季续驶里程提升约9.57%。优化型模糊控制的控制效果显著提升,冬季驾驶室加热时间缩短约18.4%;夏季驾驶室温度的波动与超调减小,电池冷却时间缩短约3.6%。Based on heat pump technology,an integrated thermal management system that fully utilizes the waste heat of the motor has been designed.The system uses heat exchangers to connect the independent circuits and achieve efficient energy utilization.In order to address the difficulty of controlling thermal management systems,this paper proposes two optimization fuzzy control approaches,anti-saturation integral fuzzy control and multi-level fuzzy control.An integrated thermal management system model is built based on AMESim,and Simulink control strategy models for working mode switching and key components are established to jointly simulate and analyze the thermal management control effect of the entire vehicle.The simulation results show that at 0℃,the integrated thermal management system reduces the cabin heating time by about 27.8%compared with the independent thermal management systems of each circuit,and the energy efficiency ratio has been increased by an average of about 31.3%,in addition the winter driving range has been increased by about 9.57%.The control effect of optimized fuzzy control is significantly improved with the heating time of the cab in winter shortened by about 18.4%,and the fluctuation and overshoot of the cabin temperature in summer reduced,and the battery cooling time shortened by about 3.6%.
