Estimation for tyre force based on sliding mode observer

The state variables and parameters about the movement of vehicle is needed for the vehicle stability control (VSC) system, such as tyre force estimation. The tyre force is estimated by using sliding mode observer and the adhesion limit condition is considered in this paper. Comparison of simulation results between extended Kalman filter and sliding mode observer are done.The simulation results show that the tyre force estimation method based on sliding mode observer is more efficient.
