A study of cornering braking control strategy based on road identification

Abstract

Identification of road friction is a prerequisite to optimize vehicle cornering braking control strategy. A maximum aligning moment method is proposed to estimate road friction coefficient using the sensors equipped with the steering system. Based on the hardware and the control logic of anti-lock braking system (ABS), an enhanced stability braking system (ESBS) is designed to improve the performance during cornering braking. Simulation and experimental results show that the estimation algorithm can identify changes of road conditions precisely and the control strategy improves braking efficiency and lateral stability of the vehicle, and thus has a high value of practical application. © Springer-Verlag 2013.
