摘　　要：为了提高生产效率,降低整车开发成本,对ADVISOR控制策略进行二次开发,将设计的模糊控制器嵌入到并联式混合动力汽车仿真模型,并在CYC_UDDS循环工况下进行仿真。结果表明:与电机辅助控制策略相比,模糊控制可以使发动机的工作点集中在高效区域,在实现扭矩合理分配的同时减少电池组SOC的波动幅度,延长电池组的使用寿命。To improve the production efficiency and reduce the development cost of the whole vehicle,the ADVISOR control strategy was re-developed,the designed fuzzy controller was embedded in the parallel hybrid electric vehicle simulation model,and the simulation was carried out under the CYC_UDDS cycle condition.The results show that compared with the motor-assisted control strategy,fuzzy control can make the engine’s operating point focus on the high-efficiency area,reduce the fluctuation range of the SOC of the battery pack while realizing the reasonable distribution of torque,and prolong the service life of the battery pack.
