TY - JOUR PY - 2023// TI - Estimation method of vehicle sideslip angle considering coupled longitudinal and lateral dynamics JO - International journal of vehicle design A1 - Zhang, Qian A1 - Zhou, Hongliang A1 - Liu, Zhiyuan A1 - Zhao, Linhui SP - 1 EP - 23 VL - 93 IS - 1/2 N2 - The coupled longitudinal and lateral dynamics control plays an important role in improving the vehicle motion performance. It is very complex to describe the lateral tyre force with a coupled longitudinal and lateral dynamics, thus making it difficult to establish a lateral dynamics model and design a sideslip angle observer. In this paper, based on the piecewise affine (PWA) description of the lateral force, a novel lateral dynamics modelling method is proposed considering coupled longitudinal dynamics. Firstly, a nominal PWA model of the lateral force is established. Secondly, by regarding the slip ratio and the dynamic load as varying parameters, we obtain a novel PWA lateral dynamics model which can describe the influence of the slip ratio on the lateral dynamics. Finally, the switched T-S observer is presented. Simulation results show the effectiveness of the proposed PWA model and the designed observer.
