and an operating element configured to execute the at least one control function on the basis of the control information presented on the display. ### Claim 2 (depends on 1) The operating device according to claim 1, wherein the operating element is operable to execute at least two different control functions, and the display is operable to present control information comprising data required for control of each of the at least two different control functions. ### Claim 3 (depends on 1) The operating device according to claim 1, wherein the at least one control function comprises trailer level regulation. ### Claim 4 (depends on 1) The operating device according to claim 1, wherein the system parameters are transmitted to the operating device via a bus during initialization. ### Claim 5 (depends on 1) The operating device according to claim 1, wherein the display is operable to present operating data that are assigned to monitoring of operating parameters. ### Claim 6 (depends on 1) The operating device according to claim 1, comprising fewer than ten operating elements. ### Claim 7 (depends on 1) The operating device according to claim 1, wherein the operating element is adapted to effect at least one of: operator control of electronic level regulation of the trailer vehicle; manual control of the position of a built-in lift axle of the trailer vehicle; control of a road finisher brake of the trailer vehicle; and control of switching outputs for lights of the trailer vehicle. ### Claim 8 (depends on 6) The operating device according to claim 6, comprising only three operating elements. ### Claim 9 (depends on 7) The operating device according to claim 7, wherein the lights of the trailer vehicle are interior lights. ### Claim 10 (depends on 1) The operating device of claim 1, wherein the at least one control function is configured on the basis of control devices of the connected trailer vehicle that are coupled to the operating device, and wherein the at least one control function is obtained by at least one of automatic querying and communication of system parameters that contain the configuration of the trailer vehicle. ### Claim 11 (depends on 3) The operating device of claim 3, wherein the operating device is located in a cab of a tractor coupled to the trailer vehicle, and wherein the operating element is configured to control the trailer level regulation control function based on the control information presented on the display from inside the cab. ### Claim 12 A method for operator control of a trailer vehicle, comprising the steps of: presenting control information comprising data required for control of a control function of the trailer vehicle on a display of an operating device; assigning to an operating element of the operating device the control function of the trailer vehicle corresponding to the control information; and continuing to present data required for control of the control function as the operating element is actuated. ### Claim 13 (depends on 12) The method according to claim 12, further comprising the steps of: actuating the operating element for execution of the control function on the basis of the control information, and actuating the operating element for execution of a second control function on the basis of control information required for control of the second control function, the first control function and the second control function being different. ### Claim 14 (depends on 12) The method according to claim 12, further comprising providing the operating device in a cab of a tractor coupled to the trailer vehicle. ### Claim 15 (depends on 14) The method according to claim 14, wherein the control function comprises at least one of electronic level regulation of the trailer vehicle, manual positioning of a built-in lift axle of the trailer vehicle, and controlling a road finisher brake of the trailer vehicle, and wherein the control function is actuated from the control device provided in the cab based on the control information displayed on the display of the operating device.
