Adaptation Of The Kinematic Train Model Using
The Interacting Multiple Model Estimator
Author(s)
F. Bohringer & A. Geistler
Abstract
This paper presents an InteractingMultiple Model (IMM) estimator that performs
a reliable train location based on soft-switching between two kinematic train models:
one assuming constant velocity and the other assuming constant acceleration.
Two sensors provide input to the system, namely an eddy current sensor device
measuring the velocity and a Global Navigation Satellite System (GNSS) sensor
unit delivering absolute position information. Simulations show that the presented
location system offers robust and accurate position information, even in case of
sensor failures or GNSS signal discontinuances.
1 Introduction
State-of-the-art location systems are mainly based on hardware installations along
the track [1]. In contrast, the presented system necessitates only train-borne sensors
to perform th
