基于目标温度的电动客车电动空调控制方法

摘要

针对电动客车电动空调能耗大的问题，提出了变目标温度的电动客车电动空调控制方法。建立了某款电动客车的电动空调仿真模型，根据环境温度和人体的热舒适性要求来对电动空调进行实时控制，并在汽车试验用城市运转循环(普通道路)下进行仿真。仿真结果表明，和常用的定目标温度的控制方式相比，对电动空调进行变目标温度控制能有效减小电动空调能耗，其中电动空调百公里能耗下降了15.90％，整车百公里能耗下降了5.52％，续驶里程上升了5.85％。%Since electric air conditioning ( E-A/C) consumes much power in pure electric city bus, this paper proposes a control method which is used to control E-A/C according the needs for the ambient temperature and human thermal comfort. In order to ver￣ify the effectiveness of the proposed method in saving energy,an E-A/C model is established and the bus running condition is simu￣lated. The simulative results demonstrate that compared to the traditional control mode,E-A/C energy consumption per hundred kil￣ometers declines by 15. 90%, vehicle energy consumption per hundred kilometers fal s off 5. 52%, automobile driving range rises 5.85%.
