摘要
能量管理策略是混合动力汽车技术中研究的重要内容之一。该文提出的扭矩管理策略具有稳态能量管理策略的特征。在Matlab/Simulink仿真平台上建立了前向式混合动力汽车模型,并在模型基础上对驱动方式和制动方式下的扭矩管理策略进行了仿真分析。仿真结果表明,扭矩管理策略将扭矩作为最主要的控制变量,以内燃机稳态效率特性图为基础,可以实现对内燃机和电机输出动力的合理分配。扭矩管理策略综合考虑了驾驶员的需求以及混合动力汽车中多个部件的特性,是一种能量的优化管理方法,达到了提高混合动力汽车动力系统效率的目的。
The energy management strategy is one of the key technologies for hybrid electric vehicles, HEVs. The torque management strategy described in this paper is based on a static energy management strategy. A forward HEV model developed in Matlab/Simulink was used to simulate the TMS for driving and braking modes. The simulation results show that the power partitioning between the internal combustion engine (ICE) and the electric motor is optimized when the torque is the major control variable and the analysis is based on the ICE static efficiency MAP. The torque management strategy, which combines the demands of the driver and the characteristics of powertrain, provides optimized energy management to improve HEV efficiency.
