Abstract
A control device for at least one electric parking brake of a vehicle brake system of a vehicle having a control instrument, to determine a setpoint variable regarding a setpoint braking torque to be generated with the parking brake and to output a control signal, the control instrument being configured to ascertain/detect, based on at least one provided signal, whether a brake booster is in at least one functionally limited or incapacitated state, and, if indicated, to determine the setpoint variable by considering at least one defined parameter regarding a requested total braking torque and to control the electric parking brake so that a corresponding actual braking torque is exertable with the parking brake. Also described is an electric parking brake for a vehicle brake system and to a vehicle brake system, and a method for operating a vehicle brake system having a brake booster and an electric parking brake.
