CONTROL OF RUNNING-GEAR HEIGHT BY MEANS OF PASSENGER BOARDING SENSOR

Abstract

A method calibrates running-gear control for a rail vehicle. In the method, at least one value of a vehicle height of a rail vehicle with respect to a railway-platform upper edge of a railway platform on the track for the rail vehicle is detected by use of at least one suitable measuring device of the rail vehicle. A predefined value of a running-gear height is adjusted on the basis of the at least one detected value of the vehicle height by a suitably configured running-gear controller of the rail vehicle.
