Claim:
1. A monitoring device for a brake booster having a pressure chamber, comprising: a brake actuation recognition device including a processor configured to: compare at least one provided modification quantity relating to a temporal change of an actual quantity relating to a pressure in a pressure chamber of a brake booster of a brake system to a specified comparison value range, wherein the actual quantity is a measured quantity; and (i) if the at least one provided modification quantity is within the comparison value range, determining that a brake actuating element situated on the brake system is in an actuation state below a specified minimum actuation state, and outputting a corresponding first information signal indicating an actuation below the minimum actuation, and (ii) if the at least one provided modification quantity differs from the comparison quantity range, determining that the brake actuating element is in an actuation state above the specified minimum actuation state, and outputting a corresponding second information signal indicating actuation above the minimum actuation; a pressure monitoring device including a processor configured to compare the actual quantity relating to the pressure in the pressure chamber of the brake booster with a specified target quantity range and, if the provided actual quantity differs from the specified target quantity range, output at least one of a corresponding pressure deviation and a warning information in a first operating mode, and not output at least one of a corresponding pressure deviation and a warning information in second operating mode; and a control device including a processor selectively controlling the pressure monitoring device into at least one of the first operating mode and the second operating mode, taking into account the information signal outputted by the brake actuation recognition device, wherein in the first operational, the control device controls a physical operation of a vehicle component.
