基于dSPACE并联式混合动力汽车能量管理策略的研究

摘要

In order to speed up the development of the vehicle controller and improve the performance of the controller,a rule-based energy management control strategy is proposed for the characteristics of an electric drive automatic transmission(EMT) coaxial parallel hybrid electric vehicle.The torque of the vehicle is taken as the foothold of the vehicle energy management,the different working modes of the system are determined and the hybrid torque allocation strategy is develop,which is embedded in the dSPACE of the hybrid vehicle rapid development platform to perform a semi-physical simulation.The simulation results meet the control requirements and proved that the energy management strategy is reasonable and effective.%为了加快整车控制器的开发速度,完善控制器性能,针对一款电驱动自动变速器EMT的同轴并联混合动力汽车的特点,提出了基于规则的能量管理控制策略.将转矩量作为整车能量管理的落脚点,确定系统不同工作模式,制定混合动力转矩分配策略,并将其整体嵌入混合动力汽车快速原型开发平台dSPACE进行半实物仿真.仿真结果达到控制要求,证实能量管理策略具有合理性和有效性.
