摘要: 建立基于神经网络的液压混合动力车辆液压蓄能器SOC荷压状态模型,通过选取某重型液压混合动力车辆,搭建Matlab/Simulink平台下仿真模型。在FUDS仿真循环工况下,分析车辆的实际车速与期望车速、车速误差参数、蓄能器SOC预测状态参数等,得出结论:在液压蓄能器ACC的荷压状态开启值为0.2,荷压状态关闭值为0.5时,发动机与蓄能器的工作协调最好。SOC值的响应较好,达到了预期效果。

Abstract: The hydraulic accumulator ( SOC) load model of hydraulic hybrid vehicles based on neural network control is established. By selecting a certain heavy-duty hydraulic hybrid vehicle , the simulation model under Matlab / Simulink platform is built. In the FUDS simulation cycle ,the actual vehicle speed and expected speed, vchicle speed error parameters,the SOC predict state parameters,etc. are analyzed. lt is concluded that when the opening value of hydraulic accumulator ACC is 0.2 and the closing value is 0. 5 ,the coordination between engine and accumulator is the best. 'The response of SOC valuc is good,and the expected effect is achieved.

Key words: hydraulic hybrid power, FUDS, neural network control hydraulic accumulator, state of charge, speed error
