摘要
通过仿真对四轮驱动混合动力汽车的能量控制策略进行分析研究,提出以扭矩作为控制策略中的主要控制变量,并根据发动机万有特性、汽车车速、电池稳态特性等因素,将整车扭矩需求合理地分配给内燃机和电机.根据车辆的动力需求,确立了动力系统各元件的匹配参数,并使用Matlab/Simulink仿真软件建立前向式混合动力车模型进行离线仿真计算.仿真结果表明,此能量管理策略可以进行合理的动力分配,并达到一定的动力系统效率.
In this paper, the energy management strategy of hybrid electric vehicle is analyzed on the basis of simulation. The torque is proposed to be the major variable of this control strategy, and the total torque be reasonably distributed to the internal combustion engine （ICE） and the motor according to the ICE universal performance, the velocity and the battery state of charge（SOC）, etc. The components of the power unit are discussed according to the vehicle requirements for power. A feed-forward HEV simulation model is developed and performed on the modeling platform of Matlab/Simulink. Consequently, the simulation result shows that the energy management strategy can control the power output of engine and motor to achieve a certain system efficiency.
