Abstract

The precise determination of the velocity of rail vehicles is fundamental for the use of modern train control systems and logistics. Eddy current sensor systems allow for a slipless estimation of the velocity based on cross-correlation techniques. Those suffer in precision when driving with very low velocity or in area with high accelerations. This paper presents an alternative estimation of the velocity in these time intervals by employing correlation optimized warping, a variant of the dynamic time warping algorithms widely used for example in speech recognition..
