- Abstract
Vehicle sideslip angle is a significant parameter for vehicle stability control. Based on the 2-DOF vehicle dynamic model, a feedback observer is built with the correction item. The estimation accuracy of the sideslip angle is improved by adjusting the feedback gain of the feedback term in the feedback observer. At the same time, the computational burden is reduced by using the three-map of tire lateral force based on the magic formula (MF) model. The simulation results show that the feedback gain plays an important role in improving accuracy of sideslip angle estimation. The estimation method can be applied to the vehicle stability control system.
