摘要
建立了基于运动学的车辆3自由度状态估计模型,分别将扩展卡尔曼滤波(EKF)、无迹卡尔曼滤波(UKF)和粒子滤波(PF)应用到车辆状态估计中,通过仿真试验比较了3种算法的估计效果。结果表明,车辆工作在线性稳定区域时,EKF算法效果最优,而车辆工作在强非线性区域并处于失稳状态时,PF算法效果最优。
Three-degree freedom vehicle state estimation model is established. Extended Kalman Filter (EKF), Unscented Kalman Filter (UKF) and Particle Filter (PF) are applied to the estimation of vehicle handling and stability state. Simulation results show that EKE algorithm performs better than both UKF and PF in linear region while PF performs best in nonlinear region.
