This paper presents a modular observer structure to estimate the tire-road forces robustly, avoiding the use of any particular tire model, and using standard signals available in current passenger vehicles. The observer consists of a feedforward longitudinal force estimation block and a hybrid lateral force estimation module formed by an Extended Kalman Filter and a Static Neural Network Structure. Road grade and bank angle are estimated using sensor fusion, where a Fuzzy Logic controller

The proposed observer is tested and veri ed using the simulation software IPG CarMaker under realistic driving situations. Lastly, the feasibility of the longitudinal force block is proved with real-time experiments.
