摘要:

为了提高汽车质心侧偏角估计的准确性,提出了一种新的、基于运动学—动力学方法的融合
估计方法。构建了质心侧偏角融合观测器(SAFO)。该SAFO 包括3 个子滤波器,每个子滤波器分别
将横向车速的初步估计结果送到主滤波器中。主滤波器根据当前车辆行驶工况和融合规则,将子滤
波器的估计结果融合成为全局意义下的质心侧偏角估计结果。结果表明:该SAFO 具有良好的估计精
度和长时间尺度下的计算稳定性,同时对横向加速度传感器偏差具有鲁棒性。因此,车辆测试数据
验证了SAFO 的性能。

Abstract:

A novel method of vehicle sideslip angle estimation was proposed based on a fusion of kinematics
and dynamics methods to improve the estimation accuracy. A sideslip angle fusion observer (SAFO) was
constructed with three local filters to estimate lateral velocities sending preliminary output to a master filter. The
master filter fuses the outputs from all local filters to calculate a global sideslip angle estimation result according
to driving information and fusion rules. The results show that the SAFO has good estimation accuracy and
stability in a long time running with good robust for sensor signal bias. Therefore, the vehicle test data verifies
the SAFO performances.
