2 . The information system of claim 1 , wherein the driving parameter is slip control of driven and/or braked wheels.
3 . The information system of claim 1 , wherein the control parameter predefined by the user includes a selection of a driving profile or a setting of an electronic stability program.
4 . The information system of claim 1 , wherein the control parameter predefined by the user sets a limit for an engagement characteristic that describes a level of the engagement in the driving parameter, wherein the output of the information to the user is suppressed in response to the engagement characteristic being below the limit.
5 . The information system of claim 1 , wherein the control parameter predefined by the user includes a setting that determines whether information about an existing or impending engagement of the transportation vehicle in a driving parameter is to be output.
6 . The information system of claim 1 , wherein the control parameter predefined by the user is used to determine whether a result of an evaluation of a driving situation is incorporated into the decision to determine whether the output of the information to the user is suppressed.
7 . The information system of claim 1 , wherein the control parameter predefined by the user is a degree of autonomy of driving of the transportation vehicle.

9 . A transportation vehicle comprising the information system of claim 1 .
10 . A method for the situational suppression of an output of information to a user about an existing or impending engagement of a transportation vehicle in a driving parameter for driving the transportation vehicle, the method comprising: determining whether an engagement of the transportation vehicle in a driving parameter is existing or impending; determining a relevance value for the existing or impending engagement in response to an engagement of the transportation vehicle in an existing or impending driving parameter; consulting at least one control parameter predefined by the user; and determining whether the information about the existing or impending engagement of the transportation vehicle in the driving parameter is to be output or suppressed based on the relevance value and the control parameter.
11 . The method of claim 10 , wherein the driving parameter is slip control of driven and/or braked wheels.
12 . The method of claim 10 , wherein the control parameter predefined by the user includes a selection of a driving profile or a setting of an electronic stability program.
13 . The method of claim 10 , wherein the control parameter predefined by the user sets a limit for an engagement characteristic that describes a level of the engagement in the driving parameter, wherein the output of the information to the user is suppressed in response to the engagement characteristic being below the limit.
14 . The method of claim 10 , wherein the control parameter predefined by the user includes a setting that determines whether information about an existing or impending engagement of the transportation vehicle in a driving parameter is to be output.
15 . The method of claim 10 , wherein the control parameter predefined by the user is used to determine whether a result of an evaluation of a driving situation is incorporated into the decision to determine whether the output of the information to the user is suppressed.

Description

PRIORITY CLAIM This patent application claims priority to German Patent Application No. 10 2023 205 232.6, filed 5 Jun. 2023, the disclosure of which is incorporated herein by reference in its entirety. SUMMARY Illustrative embodiments relate to an information system for a transportation vehicle, which is designed to output, during a journey, information to a user of the transportation vehicle about an existing or impending engagement of the transportation vehicle in a driving parameter, to a method for the situational suppression of an output of information about an existing or impending engagement of a transportation vehicle in a driving parameter for driving the transportation vehicle and to a transportation vehicle. BRIEF DESCRIPTION OF THE DRAWINGS Exemplary embodiments are described below with reference to the drawings, in which: FIG. 1 schematically shows a schematic side view of a transportation vehicle with a first exemplary embodiment of an information system; FIG. 2 schematically shows a schematic view of a dashboard or center console of a transportation vehicle with a second exemplary embodiment of an information system; FIG. 3 schematically shows a flow diagram to explain a first exemplary embodiment of a disclosed method; FIG. 4 schematically shows a flow diagram to explain a second exemplary embodiment of a disclosed method; and FIG. 5 schematically shows a mode of operation of a third exemplary embodiment of a disclosed information system. DETAILED DESCRIPTION For a long time in transportation vehicles there was a mechanical coupling between wheel brakes and an actuation device for the wheel brakes, i.e., generally the brake pedal, as standard. In the course of development toward electromobility and also toward partially autonomous or fully autonomous driving, more and more “decoupled” brake control systems are being used. This means that there is no longer a mechanical coupling between the brake pedal and the usually hydraulic brake system, such as a main brake cylinder and/or a brake caliper. The actuation of the wheel brakes subsequently takes place by way of a separate actuator. This actuator is subsequently connected to the actual brake system only via interposed sensors or electronics. Such a system is also referred to as a “Brake-by-Wire” system. As a result of the decoupling mentioned, the driver does not receive any haptic feedback from the system upon braking and, for example, their foot no longer feels it when a stabilizing wheel pressure control is implemented, such as ABS control, for example, which causes a slightly vibrating brake pedal in conventional systems. As a result of the decoupling, in particular, in the case of an electrical connection of the brake pedal, the brake control system components can be installed freely in the engine compartment, which in turn brings about an improvement in the acoustic decoupling. As a result, the driver can no longer perceive a possible brake control procedure, possibly alternatively audibly. The same is true when using electromechanical brake calipers instead of hydraulic brake calipers. In many cases, therefore, the driver will neither hear nor feel when they reach the locking pressure or trigger ABS control upon actuating the brake. Such an avoidance of sensory feedback may be desirable. For example, for reasons of comfort, such as in the case of autonomous or partially autonomous driving, for example, it can be perceived as pleasant when as many sensory influences as possible are kept from the driver. In other cases, however, information about the slip conditions at the wheel, for example, in sport driving or similarly when using the transportation vehicle on a racetrack, can be helpful or even necessary to optimize the braking point before a bend, for example. One possible measure for informing the driver of a brake control engagement is haptic, audible or visual indications. According to the prior art, these indications are output upon each brake control system engagement. In many areas, this can be perceived as distracting. In certain circumstances, a distraction by such an information system felt by the user can result in the user deactivating the associated assistance system. In particular, in the case of safety-relevant assistance systems, it is therefore highly desirable to avoid such a distraction felt by the user. The same applies to notifications about the use of other assistance systems. Such assistance systems can be a lane departure warning assistant, a speed assistant, an anti-slip control system or other assistance systems, for example. The disclosed embodiments provide a way of avoiding the driver being distracted as a result of excessively frequent information about an existing or impending engagement of the transportation vehicle in a driving parameter, but at the same time providing the driver with a sufficient amount of such information. This is achieved by an information system for a transportation vehicle of the
