Abstract: A vehicle braking model for straight line braking analysis is presented. This model includes the longitudinal vehicle dynamics, tyre dynamics, and road surface model. The developed model is tested on an asphalt surface on a step brake input. A fuzzy logic antilock brake system (ABS) controller is proposed to minimise the stopping distance under emergency braking conditions. The performance of the fuzzy logic controller with a manual brake system in an emergency braking manoeuvre is compared.

Keywords: antilock brake system (ABS); coefficient of adhesion; fuzzy logic; stopping distance; system modelling; wheel slip.
