公交智能启停系统控制研究

The control research on intelligent bus start-stop system

为解决公交车节油环保和动力问题,采用智能启停系统来改善公交车的燃油经济性和动力性。通过分析智能启停系统结构和控制方法,在AVL-Cruise软件中对加装智能启停系统前后公交车整车进行建模。通过仿真,分别计算装载智能启停系统前后公交车在ECE、EUDC、NEDC循环工况下的燃油消耗量、NEDC循环工况下的尾气排放量以及车辆动力性,结果显示加装智能启停系统后,公交车在燃油经济性、排放性和动力性方面有显著改善。最后通过实车试验验证智能启停系统的有效性。

An intelligent start-stop system was adopted to improve the fuel economy and dynamic performance of buses. The structure and control method of the system was analyzed. Models were established by AVL-Cruise software for buses installed with the system and without it. The fuel consumption of these buses was calculated in the ECE, EUDC, and NEDC circulation conditions. The exhaust emission and the dynamic performance were calculated in the NEDC circulation condition. The results show the bus installed with the intelligent start-stop system has been improved in fuel economy, emission performance and dynamic properties. Ultimately, the intelligent start-stop system has been verified by real vehicle tests.
