Estimation of Maximum Tire-Road Friction Based on Dynamic Model Reconstruction

The maximum tire road friction coefficient greatly affect the dynamic vehicle response under defined driving conditions, which makes it a crucial parameter to vehicle dynamics control and active safety systems. A maximum road friction estimation scheme was proposed in this paper, in which the instantaneous tire friction was obtained by analyzing the vehicle dynamics response, and a new transient friction-wheel slip line with one unique peak value was reshaped based on reconstruction of a dynamic tire friction model. Simulation works were completed under various driving condition, which demonstrated the validation of the proposed algorithm.
