Visually Assisted Anti-lock Braking System.

The concept of a visually-assisted anti-lock braking system (ABS) is presented. The road conditions in front of the vehicle are assessed in real time based on camera data. The surface type classification (tarmac, gravel, ice, etc.) and related road friction properties are provided to the braking control algorithm in order to adjust the vehicle response accordingly. The system was implemented and tested in simulations as well as on an instrumented sub-scale vehicle. Simulations and experimental results quantitatively demonstrate the benefits of the proposed system in critical maneuvers, such as emergency braking and collision avoidance.
