并联式混合动力电动汽车模糊逻辑控制策略的设计与仿真

在兼顾发动机效率和排放前提下,考虑电池充放电平衡,提出了一种模糊逻辑控制策略。将其嵌入仿真软件ADVISOR中,并在不同道路循环和不同控制策略中进行仿真计算。结果表明,模糊逻辑控制有较好的经济性、鲁棒性,能合理分配发动机和电动机转矩,并保持电池SOC较小的变化范围。

A fuzzy logic control strategy is put forward con- sidering battery charge or discharge balance based on engine efficiency and emmision. It is set in ADVISOR and simulated under different road cycles and control strategies. The result shows the fuzzy logic control has well economy and robustness. It can distribute the torque between the engine and motor reasonably, and keep the balance of SOC.
