制动器耗散功率原理在ABS标定匹配中的应用（Application of Brake Decay Power in Calibration of ABS）
汽车防抱制动系统 制动器耗散功率 标定匹配
2009/9/25
为解决ABS逻辑门限值方法匹配成本高、周期长的问题，将制动器耗散功率原理应用于匹配中。结合逻辑门限值与制动器耗散功率的各自优点，将制动器耗散功率原理能自适应识别各种路面状况的特点应用于匹配中；根据制动器耗散功率极大值对应的滑移率略小于临界滑移率且相差不大的原理，采用制动器耗散功率极大值对应的滑移率代替峰值附着系数对应的滑移率对ABS进行控制；滑移率与制动器耗散功率曲线获得较为简单，因此可以大大提高...
