摘    要:经过系统研究并联混合动力汽车的控制策略,对并联混合动力汽车提出一种基于模糊逻辑和PID控制的混合能量管理策略,通过模糊逻辑控制器对引擎和电机的期望转矩进行分配,借助PID电量持续策略实现整个循环工况电池荷电状态SOC平衡.为了验证能量管理策略的有效性,对该策略进行仿真分析.仿真结果表明,该策略对提高混合动力汽车的动力性和燃油经济性、改善排放有明显的作用.

关 键 词:能量管理策略  混合动力汽车  转矩分配  充电持续

Abstract:After systematical investigation of various control strategies for parallel hybrid powered vehicles,a blend energy management control system for them was presented.On the basis of combined fuzzy logic scheme and PID strategy.The anticipative torque was distributed between the internal combustion engine and electric with the fuzzy-logic controller and the PID motor charge sustaining strategy was used to ensure a better balance of battery's charging during the whole driving cycle.Computer simulation was carried out to evaluate the energy management system proposed.It was found that significant improvement on fuel economy and vehicle's power performance could be achieved with remarkable emission reduction.
Keywords:energy management  hybrid powered vehicle  torque distribution  charging sustenance
