1、同济大学汽车学院博士学位论文汽车底盘集成制动力控制系统研究与开发姓名:汤东胜申请学位级别:博士专业:车辆工程指导教师:吴光强20040630脚。然后,使用单片机C语言,编制了完整的控制程序。通过把ECU嵌入到硬件在环仿真设计平台,并运行控制程序和车辆系统动力学实时仿真模型,对各控制功能进行了仿真研究,结果表明,所开发的ECU工作可靠,性能稳定,效果理想。模糊控制是在模仿专家经验的基础上利用模糊数学的基本原理建立起来的一种智能控制方法,因为其鲁棒性和对非线性系统的适应性,模糊控制非常适合应用在车辆AD
2、S系统。基于滑移率或者车轮加减速度的ABS模糊控制器,较多的文献已有论述。本文从实际工程应用的角度出发,详细地建立了基于车轮加减速度的ABS模糊控制方法,通过使用三维输入,较好的克服了以往基于车轮加减速度模糊控制中轮速波动较大的缺点,获得了较好的控制效果。关键字:底盘集成控制制动力控制逻辑门限状态控制硬件在环仿真模糊控制AbstractWiththerapidsocietyimprovementandthetechnologydevelopment,peoplearethrowingmoreandm
