Abstract

A method determines the energy consumption of a rail vehicle during a test drive. The method includes: a) providing a locomotive system having a brake locomotive component and a test locomotive component, b) providing a test route, c) providing basic data for the test drive having information about the train composition, load, route profile and timetable, d) determining driving data from the basic data, and transmitting the driving data to the control system, e) determining braking data from the basic data, and transmitting the braking data to the control system, f) carrying out the test drive with the locomotive system on the test route and measuring the energy consumption of the test locomotive component while this is controlled in accordance with the driving data and is simultaneously braked by the brake locomotive component in accordance with the braking data. A corresponding system is provided for implementing the method.

Dependent claims

A method for determining energy consumption of a rail vehicle during a test run, which comprises the steps of:

a) providing a locomotive system having a brake locomotive component and a test locomotive component being coupled together, wherein the brake locomotive component is moved by the test locomotive component during the test run, and wherein a control system controls the test locomotive component and the brake locomotive component during the test run;
b) providing a test track on which the locomotive system runs during the test run;
c) providing basic data about the test run, including at least information on a train composition, loading, track profile and timetable;
d) determining running data from the basic data, the running data including at least information on a tractive force and speed profiles of the test run and are configured to control the test locomotive component during the test run on the test track, and transmitting the running data to the control system;
e) determining braking data from the basic data, which contains at least information on an inhibition during the test run due to the train composition, the loading and/or the track profile and are configured to brake the brake locomotive component during the test run on the test track in accordance with the inhibition, and transmitting the braking data to the control system;
and
f) carrying out the test run with the locomotive system on the test track and measuring the energy consumption of the test locomotive component while it is running according to the running data and at a same time is braked by the brake locomotive component in accordance with the braking data.
