摘　　要：为了降低电机峰值扭矩,提高车辆在频繁启停时的动态性能,建立一种具备多模式切换和制动能量回收功能的载电液驱车辆模型。根据车辆的基本工作原理和模式,完成了动力传动系统的参数匹配,设计了一种基于规则的动态优化能量管理策略,实现能量分配控制和工作模式的实时切换。利用AMESim和Simulink软件对该模型进行建模,并在认证的FTP-75和WLTC循环工况下进行联合仿真。仿真结果显示,与同等配置的纯电动汽车相比,载电液驱车辆在FTP-75工况下的电池消耗率降低了6.2%。To reduce motor peak torque and improve electric vehicle dynamic performance during frequent start-stop operations,a model of an electrically-powered hydraulic vehicle with multi-mode switching and regenerative braking was developed.Based on the operating principles and modes,the dynamic parameters were matched,and a rule-based,dynamically optimized energy management control strategy was proposed to achieve energy distribution control and real-time switching of operating modes.The vehicle modeling was conducted using AMESim and Simulink software.A co-simulation was conducted under certified FTP-75 and WLTC conditions.The simulation results show that,compared with a pure electric vehicle,the electrically-powered hydraulic vehicle reduces battery consumption by 6.2%under FTP-75 conditions.
