During the braking of a railway vehicle, excessive slide between wheel and rail can occur due to temporarily degraded adhesion by wet or contaminated rail surface. This can damage the wheel tread, and the damaged wheel affects seriously the safety and ride comfort of the railway vehicle. To prevent from excessive slide between wheel and rail, braking control using wheel-slide protection (WSP) logic is required. In this paper, we present an effective WSP logic to maximize the usage of adhesion force, and demonstrate experimentally the validity of it using a brake HILS (hardware-in-the-loop simulation) system developed in our laboratory.
