Estimation of vehicle speed fuzzy-estimation in comparison with Kalman-filtering

Abstract

The aim of the system described is to measure the wheel slip with an accuracy of 1% without using expensive sensors. The multisensor data fusion is used with the integration of the commonly used antilock braking system wheel speed sensors. Two approaches are compared whereby the fuzzy approach is new and the Kalman approach is taken from the literature. Furthermore the possibility of estimating the road slope with this system is shown.
