Development of a New Wheel Slide Protection System Using a New Detection Algorithm

Abstract

Reducing the braking distance is very important to improve the safety of a railway system. However, increasing braking force to achieve this often causes wheel slide under wet conditions because the adhesion force between the wheel tread and rail governs braking performance. This has led to the development of a number of methods including "Anti-skid (Anti-lock) Brake System (ABS)," "Wheel Slide Protection system (WSP)," etc,. This paper proposes an advanced WSP using a new algorithm to detect wheel slip to achieve a higher level of performance than current systems. We also show the effectiveness of the proposed method by means of line tests.
