Abstract: A design methodology for an anti-lock braking system (ABS) controller for four-wheeled road vehicles is presented. In the study, a flexible approach was adopted considering integration with an integrated active safety system control structure. In the hierarchical control strategy proposed for the ABS controller, a high-level controller, through vehicle longitudinal acceleration-based estimation, determines reference wheel slip values, and a low-level controller attempts to track these reference slip signals by modulating braking torques. Two control methods were investigated for the design of the low-level controller: fuzzy logic control and PID control.
