Abstract :
In order to meet the cost requirement of side slip angle measured directly in vehicle active safety control systems, a new combined observer for estimating side slip angle is proposed. In the observer, the adaptive Kalman filter and full-order state observer are employed. Effectiveness of presented method is confirmed by simulation of sinusoidal driving and double lane maneuver. The results show that the proposed method has good robustness and accuracy both in tire linear and nonlinear area.
