Modeling and Control of Anti-lock Braking systems considering different representations for tire-road interaction

Mobility and traffic safety is one of the major concerns in today's society as traffic accidents continue to be a leading cause of death on the planet. Traffic safety is influenced by several factors, one of the most important being vehicle control, by the driver, in all situations. Modern safety systems, among them, the anti-locking brake system (ABS) has allowed the reduction of uncontrollable incidents in traffic, protecting the passengers from accidents. Together with safety issues, the costumers growing demands when purchasing vehicles regarding efficiency, lower consumption, reduced emissions and high comfort encourages engineers to seek for better model representations of the vehicle dynamics and improved and simplified control techniques. This article approaches a modeling and simulation of an ABS system considering different theories for implementation of tire-road contact.
