基于一种插电式混合动力汽车的控制方法研究

Based on The Control Strategy of APlug-in Hybrid Electric Vehicle

针对现有插电式混合动力汽车的控制方法的设计所存在之缺陷,文章提出了将插电式混合动力汽车整车需求转矩Treq、动力电池的荷电量SOC和车速V,传递给控制模块的动力控制系统的方案。该方案的关键之处是采用模糊分层控制,使得混合动力汽车动力控制系统有效地控制车辆发动机和驱动电机达到行驶时期的最佳状态,从而交大幅度地提高了汽车的续航能力。通过对该控制方法地建模仿真,结果表明文章设计的模糊分层控制方法可以满足要求。

In view of the defects in the design of the current control methods of plug-in hybrid electric vehicles,this paper proposes a scheme of transferring the demand torque Treq,the SOC of power battery and the speed V of plug-in hybrid electric vehicles to the power control system of the control module.The key of the scheme is to adopt the fuzzy hierarchical control,so that the hybrid electric vehicle power control system can effectively control the vehicle engine and drive motor to reach the optimal state during the driving period,thus greatly improving the vehicle's endurance.The simulation results show that the fuzzy hierarchical control method can meet the requirements.
