摘要

By adopting a measurement noise adaptive Kalman filter and using the accurate information of driving torque provided by in-wheel motor driven electric vehicles, the tire longitudinal forces are extracted. Meanwhile, this paper puts forward a method to modify the original Dugoff tire model to expand the tire force working range as well as improve the precision. Then, the joint estimation of road friction and vehicle sideslip angle is carried out based on a reduced-order extended Kalman filter with longitudinal forces as inputs. Simulation results show that the algorithm can accurately estimate road friction coefficient when vehicle is under lateral dynamics.
