基于卡尔曼滤波的车辆状态与路面附着估计
Journal of South China University of Technology(Natural Science Edition)（2014）
Abstract
建立了采用Dugoff轮胎模型的三自由度车辆估算模型,设计了基于联邦卡尔曼滤波理论的车辆行驶状态估计算法与基于扩展卡尔曼滤波理论的路面附着系数估计算法,使车辆状态估计与路面附着估计相互联系、闭环反馈、同时进行.选择典型工况,应用CarSim与Matlab/Simulink联合仿真实验对车辆状态算法和路面附着估计算法进行了验证.结果表明:文中算法能够实现对车辆状态及路面附着系数的准确估计.
