Abstract

A method for the operation of a brake control system for a rail vehicle that includes a brake system that has at least partially one friction brake, includes determining at least one characteristic curve using at least one virtual and/or at least one actual reference braking journey of the rail vehicle, which characteristic curve sets at least one control variable for maintaining at least one performance variable in relation to one another, recording the characteristic curve in the brake control system; and using the characteristic curve functioning as a basis for controlling the brake system of the rail vehicle. Furthermore, a brake control system, a brake system, and a rail vehicle are provided.

First claim

The invention claimed is:

1. A method for operating a brake control system for a rail vehicle having a brake system, wherein the brake system comprises a friction brake, the method comprising:
determining at least one characteristic curve using at least one virtual and/or at least one real reference braking journey of the rail vehicle, the characteristic curve correlating at least one control variable for maintaining at least one performance variable;
storing the characteristic curve in the brake control system; and
using the characteristic curve as a basis for actuating the brake system of the rail vehicle,
wherein multiple characteristic curves are provided that collectively provide a multidimensional performance map, and
wherein the multiple characteristic curves are used as an algorithm in the controlling of an operating brake of the brake system and as a fixed characteristic curve in controlling an emergency brake of the brake system.

2. The method of claim 1 , wherein the at least one control variable describes force and/or pressure and/or current and/or time.

3. The method of claim 1 , wherein the at least one performance variable describes braking travel and/or deceleration and/or acceleration and/or traction wheel to rail and/or reaction time.

4. A brake control system for a rail vehicle having a brake system, wherein the brake system includes a component a friction brake and the brake control system comprises:
at least one control unit that includes at least one data input interface, at least one data output interface, at least one control data set storage device, and at least one sensor, wherein control variables and/or performance variables are determined at least in part by the sensor;
at least one computing unit determines at least one characteristic curve that correlates at least one control variable for maintaining at least one performance variable based on at least one virtual and/or at least one real reference braking journey of the rail vehicle, wherein the control unit, via the data input interface, stores the characteristic curve in the control data set storage device and the characteristic curve is used to actuate the brake system by the control unit, via the data output interface, such that the characteristic curve is used as a basis for actuating the brake system of the rail vehicle,
wherein multiple characteristic curves are provided that collectively provide a multidimensional performance map, and

wherein the multiple characteristic curves are used as an algorithm in the controlling of an operating brake of the brake system and as a fixed characteristic curve in controlling an emergency brake of the brake system.

at least one control unit that includes at least one data input interface, at least one data output interface, at least one control data set storage device, and at least one sensor, wherein control variables and/or performance variable are determined at least in part by the sensor;
at least one computing unit determines at least one characteristic curve that correlates at least one control variable for maintaining at least one performance variable based on at least one virtual and/or at least one real reference braking journey of a rail vehicle, wherein the control unit, via the data input interface, stores the characteristic curve in the control data set storage device and the characteristic curve is used to actuate the brake system by the control unit, via the data output interface, such that the characteristic curve is used as a basis for actuating the brake system of the rail vehicle,
wherein multiple characteristic curves are provided that collectively provide a multidimensional performance map, and
wherein the multiple characteristic curves are used as an algorithm in the controlling of a friction brake of the brake system and as a fixed characteristic curve in controlling an emergency brake of the brake system.
