并联混合动力汽车扭矩管理的模糊控制与仿真

并联混合动力汽车中内燃机和电机之间存在动力的耦合和分离过程,能量管理策略比较复杂。为了进一步合理分配内燃机和电机的动力输出,增强其能量管理策略的鲁棒性,文中分析了电辅助控制策略的不足,提出了基于模糊逻辑控制的包含驾驶员扭矩识别和蓄电池功率平衡的并联混合动力汽车扭矩分配策略,并利用ADVI SOR2002的仿真环境,完成了该模糊逻辑扭矩控制模块的仿真。结果表明,模糊逻辑控制策略满足控制目标,对提高汽车的动力性和燃油经济性、改善排放、保证蓄电池的充放电功率平衡有明显的作用。

Fuzzy-Logic-Based Torque Control and Simulation for Parallel-Type Hybrid Vehicle

There is a power coupling and separating process between ICE and motor in the parallel-type hybrid vehicle, and the energy management strategy is comparatively complex. To further distribute the power output of the ICE and motor reasonably and improve the robust of energy management strategy on PHEV, the insufficiency of electric-assisted control is analyzed and the torque management strategy including driver's torque identification and the power balance controller of the battery based on fuzzy logic control for parallel-type hybrid vehicle is put forward. The module simulation of the fuzzy logic torque control is completed by using the mimic environment of ADVISOR2002.The result shows that the fuzzy logic control strategy can meet the control objectives and also improve the dynamic, fuel economy and emission, and can further promote the power charging and discharging balance of the battery.
