Abstract:

The significance of the side slip angle estimation for vehicle stability control was discussed. The research of vehicle side slip angle estimation was divided into four aspects: measuring instrument, estimation algorithm, physical model and tire model. Then research progresses on vehicle side slip angle estimation were summarized and analyzed both at home and abroad. The emphasis was put on the comparison of advantages and disadvantages for each estimation algorithm. Finally, the problems and development were presented, which contained model accuracy, signal fusion, error elimination of sensors and parameter adaptation. The parameter adaptation will be the key for research of estimation algorithm.

Key words: vehicle, side slip angle, state estimation, parameter adaptation

摘要:

阐述了汽车质心侧偏角估计对于汽车稳定性控制的重要意义。从量测仪器、估计算法、物理模型、轮胎模型四个方面对国内外的质心侧偏角估计的研究进行了归纳、分析,重点列举比较了各类估计算法的优缺点,最后指出了建模的准确性、不同传感器信号的融合问题、传感器误差的处理、参数的自适应四个方面存在的问题以及发展趋势,并着重指出了参数自适应将是算法研究的重点。
