Plug-in混合动力汽车能量管理策略优化设计(Optimization of Plug-in Hybrid Electric Vehicle Energy Management Control Strategy)
Plug-in混合动力汽车 能量管理策略 优化
2009/9/25
应用PSAT前向仿真软件及矩阵分割全局优化算法,对并联式Plug-in混合动力汽车(PHEV)在不同电能消耗续驶里程(CDR)下的能量管理策略进行了优化设计研究。结果表明:PHEV电能消耗续驶里程越大,优化控制参数对整车经济性影响越小;小CDR优化控制参数的整车平均经济性能好于大CDR优化控制参数;利用优化设计得到的PHEV能量管理策略可以使整车平均等价油耗降至2.70 L/(100km),相对于...
考虑油门开度快速变化的自动变速器换挡控制策略(AMT Shift Control Strategy Based on the Fleetness Changing of the Gas Pedal Aperture)
自动变速器 油门开度变化率 换挡
2009/9/25
在机械自动变速器三参数(油门开度、车速、加速度信号)换挡控制中,汽车惯性大会引起汽车车速响应速度相对于油门开度变化的滞后,在油门开度变化率比较大的情况下易出现频繁换挡现象。本文将油门开度变化率作为输入参数,提出了换挡四参数模糊控制方法。同时针对四参数模糊控制输入参数多、模糊规则多的问题,提出了双模糊四参数控制器方法,减少了模糊规则的数量,提高了处理器的运行能力。仿真结果验证了控制策略的正确性。
