摘要
分析了电控液压制动系统结构组成及工作原理,针对系统动态响应特性,利用开发的数据采集电控系统试验台,在Codewarrior开发环境下编写测试程序并嵌入系统电子控制单元,进行了系统典型工况的增压、减压和保压特性试验,获得了系统在典型工况下的压力变化特性。结果表明:系统压力动态响应和可控性良好,能够应用于车辆底盘集成控制系统中,可为理论研究、控制策略开发和实车试验提供重要参考价值。
The pressure characteristic of vehicle brake system is a key factor influencing the braking performance.The structure and working principle of an electronic hydraulic brake system are introduced.Aiming at the dynamic response characteristics of the system,test trails of increasing pressure,reducing pressure and maintaining pressure are conducted in typical conditions.The trails are conducted on a developed test bench with data acquisition control system,and the test program is written and embedded into the electronic control unit in Codewarrior development environment.Form these trials the brake system pressure variation characteristic in typical operating conditions is acquired.Test results show that the dynamic response and controllability of pressure are favorable,and could be applied in vehicle chassis integrated control system.This study may provide important reference for further theoretical research,development of control strategy and the real vehicle test.
