Abstract:
In this paper, the use of adaptive anti-lock braking system (A-ABS) comprising of a road
surface identification (RSID) system and road surface information modules is presented. The
proposed ABS system is capable of identifying and differentiating different types of road surfaces, and
applying an amount of brake force appropriate to the road surface type being encountered in order to
prevent wheel lockup as well as to minimize the braking distance. A discriminative hierarchical
evolutionary fuzzy system learns and identifies on-the-fly the road surface characteristics, from a
set of built-in road surface information modules, in a closed-loop adaptive configuration. The closed-loop
nature of RSID allows the system to adapt and respond very fast to a sudden change in surface condition.
In order to verify the performance of the proposal, simulation results obtained from cars equipped with
A-ABS, a reference ABS, and a non-ABS are provided and discussed.
