Abstract

Tire-road friction characteristics are deeply interlaced with all vehicle safety oriented control systems, as road conditions strongly affect the control schemes behavior. In this work we focus on estimating the peak-value of the tire-road friction curve, as this is the stability boundary for the wheel braking dynamics. Moreover, we show how such algorithm can be employed as a supervisory control to enhance safety properties and performance of current anti-lock braking systems. The proposed strategy is analyzed and tested for different sensors´ configurations, i.e., with and without longitudinal wheel slip measurement available and its validity is assessed on experimental data collected on a test vehicle
