混联式混合动力客车驾驶员风格自适应控制策略研究

Research of Adaptive Control Strategy based on Driver Style Recognition for a Series-Parallel Hybrid Electric City Bus

以进一步提高新型混联式混合动力客车燃油经济性为目的,针对目前只能单纯反映汽车行驶状态的能量管理优化控制策略的局限性问题,制定驾驶员风格识别的模糊规则,并结合功率均衡控制策略思想及基于油门踏板开度的电池功率控制算法,建立驾驶员风格自适应控制策略,通过仿真结果表明,其燃油经济性比单纯的能量管理优化控制策略提高7.91%。

To further improve the fuel economy of a novel series--parallel hybrid electric bus （SPHEB） for purpose, and for the problem that the most current control strategy only reflect the driv- ing state of vehicle and the limitation of their application, a driver style adaptive control strategy is de- veloped, which is constituted a fuzzy rule based driver style recognition, and integrated power balan- cing strategy with accelerator pedal opening control algorithm of battery power, the adaptive control strategy of driver style is built. The results of simulation demonstrate that the proposed strategy can be more efficient that the normal strategy, the improvement of fuel economy is up to 7. 91%.
