Method for actuating a mechanism in a brake booster unit of a braking system and braking system

A braking system, comprising:

• a brake booster unit;
• and
• a control unit of a vehicle system;
• wherein the brake booster unit is connected to the control unit and can be connected to a pressure controller or comprises a pressure controller, and wherein the control unit is configured to:
• ascertain, using the control unit, whether a driver's braking request has ended after a preceding braking operation by the brake booster unit or whether there is no driver's braking request at the brake booster unit after a preceding braking operation by the brake booster unit;
• to detect whether an operational disruption of the brake booster unit is present,
• detect whether there is an operational disruption of the pressure controller, wherein the pressure controller is connected to or comprised by the brake booster unit and is configured to generate a braking pressure and/or a resetting pressure at a master brake cylinder unit of the brake booster unit, and
• generate, using the vehicle system, a predetermined minimum pressure in the master brake cylinder unit and thereby to reset a mechanism and thereby reset a master brake cylinder into a neutral position with reduced or no braking effect on a brake element when the driver's braking request has ended or when there is no longer a driver's braking request, wherein the generating of the minimum pressure can be controlled by the control unit of the vehicle system.
