摘要
为了提高电动大客车的制动安全性能和制动能量回收能力,设计研究了一种较为智能化的制动系统——电控气压制动系统。在此基础上建立了车辆制动过程的相关模型,制定了适合于电控气压制动系统的制动力分配策略,并对车辆的制动过程进行了仿真分析。仿真结果表明:制动力分配策略是合理的,在保证制动安全性能的前提下,车辆取得了很好的制动能量回收效果,体现了电控气压制动系统在制动力分配和与再生制动协调方面的优势。
In order to improve electric bus＇ safety in braking and effectiveness in energy regeneration,a more intelligent braking system was designed,called electric-control air braking system.The related models of braking process were established.A braking force distribution strategy which was appropriate to electric-control air braking system was proposed.Then the vehicle braking process was simulated.The results show that the braking force distribution strategy is reasonable,in ensuring braking safety condition,and the vehicle can achieve good braking regeneration effect.The advantages of electric-control air braking system in braking force distribution and coordination with regenerative braking are reflected.
