摘　　要：针对丰田PRIUS混合动力汽车,提出一种基于二次型最优控制理论的新能量优化管理策略,该策略结合规则构造二次型性能指标,通过限制发动机功率的大幅频繁波动,在保证车辆动力性能的同时,达到间接降低整车油耗的控制目标。对ADVISOR软件进行了二次开发,建立了车辆仿真模型,并在不同工况下验证了策略的有效性。仿真结果表明:在不同的道路工况下,该能量优化管理策略比基于规则的能量管理策略具有更好的燃油经济性。A new energy optimization strategy for Toyota PRIUS hybrid electric vehicle is proposed based on the linear optimal control theory. In this strategy a quadratic performance index is built combined with several rules to restrict frequent and large-scale fluctuation on engine output power, thus, realizing direct reduction of fuel consumption while still maintaining the vehicle good driving performance. Based on the second development of ADVISOR software, the vehicle simulation model is established to verify the effectiveness of the proposed strategy. Simulation results show that the energy optimization strategy has better oil-saving effect than the rule-based energy management strategy over different driving cycles.
