carrying out a reference operation and detecting at least one type of real reference operating parameter of the brake system; based on the detected at least one type of real reference operating parameter, producing a virtual model of the brake system with an initial virtual control data set that corresponds to the initial control data set; based on the virtual model, carrying out at least one virtual test operation to check compliance with the predefined approval specifications; based on of the virtual test operation, checking the virtual control data set to determine to what extent the virtual test operation requires alteration so that the predefined approval specifications are achieved by the brake system, and determining at least one correction factor to obtain a corrected virtual control data set.

2 . The method of claim 1 , further comprising checking, based on the corrected operating parameters, at least one checking operation to check actual attainment of the predefined approval specifications.

3 . The method of claim 1 , wherein an initial and/or initial virtual and/or corrected virtual control data set comprises at least one value, which is connected in relation to a braking force and/or a braking force distribution and/or a control device algorithm of the brake system.

4 . The method of claim 1 , wherein, based on the corrected operating parameter, the initial control data set is modified in such that the brake system satisfies the approval specifications.

5 . The method of claim 1 , wherein the checking process of the operating parameters comprises a consideration of differences between the virtual test operation and the reference operation based on the virtual test operation.

6 . The method of claim 5 , wherein the consideration of differences is a consideration of differences between the virtual test operation and the reference operation in comparison with the predefined approval specifications.

7 . The method of claim 1 , wherein the virtual test operation comprises checking whether the virtual model with the initial virtual control data set or with the virtual control data set modified during the test operation satisfies the predefined approval specifications.

8 . The method of claim 7 , further comprising a virtual control data set which satisfies the predefined approval specifications as a corrected control data set to the mechanical system.

9 . The method of claim 1 , wherein the brake system is a pneumatic and/or hydraulic brake installation of a rail vehicle.

11 . A system for putting into operation a brake system with predefined approval specifications, wherein the brake system has at least partially a friction brake, wherein the system comprises at least:
a brake system having at least one control unit, wherein the control unit has at least one data input interface and at least one data output interface as well as at least control data set memory; at least one sensor for detecting a type of real reference operation parameters of the brake system in a reference operation; at least one simulation unit for generating a virtual model of the brake system with an initial virtual control data set which corresponds to the initial control data set, based on the reference operation parameters; and at least one checking unit for carrying out at least one virtual test operation based on the model to check the attainment of the predefined approval specifications, wherein based on the virtual test operation, the virtual control data set is checked by the checking unit to determine to what extent the virtual test operation requires adjustment for the pneumatic system to attain the predefined approval specifications, and wherein the checking unit determines at least one correction factor to obtain a corrected virtual control data set.

12 . The system of claim 11 , further comprising at least one correction unit provided to transmit the corrected virtual control data set to the control unit of the brake system, to carry out at least one checking operation based on the corrected operating parameter to check actual attainment of the predefined approval specifications.

13 . The system of claim 11 , wherein the brake system is a pneumatic and/or hydraulic brake installation of a rail vehicle.

14 . The system of claim 11 , wherein a method operation of the brake system is performed with predefined approval specifications, wherein the method comprising:
