Method and system for obstacle identification during and after train coupling

Abstract

A method, a system, and a train control apparatus for the identification of obstacles while an automatically controlled active train approaches a passive train for coupling. At least one first onboard sensor of a first sensor type is used to identify obstacles when the distance between the trains exceeds a predetermined threshold value. At least one second onboard sensor of a second sensor type which differs from the first sensor type is used for the identification of obstacles when the distance is below the predetermined threshold value. The first sensor is ignored for the identification of obstacles when the distance is below the predetermined threshold value. The system includes the first and second sensors, and a train control apparatus which is configured to perform the method. A computer program product has instructions for performing the method.
