Antilock brake system modelling and fuzzy control

A vehicle braking model for straight line braking analysis is presented. Th is model includes the longitudinal vehicle dynamics, tyre dynamics, and roa d surface model. The developed model is tested on an asphalt surface on a s tep brake input. A fuzzy logic antilock brake system (ABS) controller is pr oposed to minimize 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.
