IEEE Transactions on Intelligent Vehicles, Institute of Electrical and Electronics Engineers, 2018, 3 (4), pp.486-500. ⟨10.1109/TIV.2018.2873906⟩

A new approach to estimate the tire-ground forces at each tire position is provided in this paper. Our method exploits two model realizations, on the one hand, the famous bicycle model is used to estimate the longitudinal/lateral tire-ground forces a
