State-of-the-Art of Vehicle Side Slip Angle Estimation

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.
