Road Adhesion Coefficient Estimation

Applied Mechanics and Materials, 2011
Taking four in-wheel-motor electric vehicle as research subject, the paper focuses on the estimation of road adhesion coefficient based on curve. Through adding a forget factor, an improved algorithm on the basis of Forget Kalman Filter is proposed to estimate the slope of the curve at low slip rate.

Estimation of Road Adhesion Coefficient Based on Tire Aligning Torque Distribution

Journal of Dynamic Systems, Measurement, and Control, 2017
Road adhesion coefficient is an important parameter in vehicle active safety control system. Many researchers estimate road adhesion coefficient by total tire self-aligning torque (SAT, also called front-axle aligning torque), which obtains the average road adhesion coefficient of front wheels, thus leading large estimation error.
