Abstract
A method for operating an automated parking brake in a motor vehicle, having a hydraulic actuator for producing a hydraulic force component and an electromechanical actuator for producing an electromechanical force component, includes superimposing the hydraulic force component and the electromechanical force component to obtain a total clamping force for a parking brake operation, and maintaining the total clamping force by self-locking of the parking brake. The method further comprises during the parking brake operation, setting at least one defined hydraulic pressure level using the hydraulic actuator, and locking-in a defined hydraulic pressure level with a valve when the at least one defined hydraulic pressure level is reached.
