摘　　要：通过分析并联混合动力电动汽车的结构和工作模式的切换过程,讨论了并联混合动力汽车进行发动机调速控制的必要性。对单轴并联混合动力汽车的发动机进行了PID调速方法研究,搭建了试验台架系统,以dSPACE快速控制原型工具为控制器,进行了PID参数整定和调速试验。试验表明,在并联混合动力状态切换过程中,发动机调速系统实现了调速快、波动小和运转稳定的目标,能够满足动力系统进行快速状态切换的需求。By analyzing the structure the working mode,and the switching process of parallel hybrid electric vehicle,the importance of engine speed regulation was discussed.Then the method of PID speed regulating for single axle parallel hybrid vehicle was researched and the test bench was built.Finally,the identification of PID parameters and the speed regulating experiment was carried out with dSPACE rapid control prototype tool.The results show that the PID speed regulation system can meet the rapid state-switching requirement of parallel hybrid vehicle by fast response,little fluctuation and smooth running.
