摘　　要：为实现底盘集成控制系统主动液压制动精细调节,对系统液压制动执行机构原理和轮缸压力调节特性进行了理论分析,搭建液压制动系统试验台,进行了增、减压试验研究。在此基础上提出了基于三维数表的液压制动压力估算方法,并进行了开、闭环试验验证。结果表明,所设计的压力估算方法能够比较精确地估算轮缸压力。In order to achieve pressure fine regulation for integrated chassis control,the operating mechanism principle of hydraulic brake system and the regulating characteristics of wheel cylinder pressure were analyzed.Pressurization and decompression experiments were carried out on the hydraulic test platform.A hydraulic brake pressure estimation based on 3-D data sheet was suggested.Comparison experiments verified this method with a satisfactory exactitude on both open-loop and closed-loop conditions.
