Review on vehicle sideslip angle estimation

The control of vehicle stability is significantly influenced by the pivotal role of the sideslip angle, and it is a major parameter in intelligent vehicle systems. The immediate and precise determination of sideslip angle forms the foundation for stability systems. Exact calculation of sideslip angle enables the real-time assessment, allowing for timely intervention to ensure safe driving, mainly from three aspects: physical model, estimation algorithm and adaptive parameter estimation method. Comparing the estimated sideslip angle of body dynamics model, tyre model and steering system model, which could be concluded that prevailing approach for sideslip angle estimation is dynamic estimation method. An analysis is conducted to examine the variations among different estimation algorithms used for the calculation of the sideslip angle; also, the advantages and disadvantages of various observers are expounded. Finally, we present an effective implementation of adaptive parameter estimation to enhance the accuracy of sideslip angle.
