并联混合动力驱动系统模糊控制策略研究

介绍了ADVISOR的一种兼顾排放的并联混合动力模糊控制策略,并对该控制策略进行了有益的改进。改进的控制策略以发动机的转矩需求、电池荷电状态SOC和电机转速作为输入,以发动机的实际工作转矩作为输出,达到优化发动机工作点、电机的效率和平衡电池SOC的目的。最后,通过整车循环工况验证了该模糊控制策略对整车经济性和排放性以及电机工作效率的改善。

Research on Fuzzy Logic Control Strategy for the Propulsion System of Parellel Hybrid Eelectric Vehicle

A kind of parellel hybrid electric vehicle control strategy taking emission into account was introduced, and some beneficial improvements to this control strategy were made. The improved control strategy made demanded engine torque, battery SOC and motor rotating speed as inputs, and makes the practical engine output torque as output. The aim of the improved control strategy was to optimize the engine working point and motor efficiency and to balance the battery SOC. In the end, through a driving cycle, the author validated the superiority of the improved control strategy to improve the vehicle economy, emission and the motor efficiency.
