Abstract
A vehicle brake system having a hydraulically actuable disc brake device which has an electromechanical actuating device for activating a parking brake function, wherein the vehicle brake system has a hydraulic circuit with a hydraulic pressure source and actuable hydraulic functional elements, in order to hydraulically actuate the disc brake device in accordance with a service brake action of a driver or an automatic activation of a driving assistance system, wherein, furthermore, the vehicle brake system has a control device, in order to actuate the electromechanical actuating device in accordance with a parking brake action of the driver or an automatic activation of the parking brake function. In order to avoid abrupt release of the parking brake function, it is provided here that the control device is configured for actuating at least one of the hydraulic functional elements in such a way that, in order to release the parking brake function, a hydraulic fluid volume is isolated in the disc brake device by actuation of the electromechanical actuating device and the hydraulic fluid volume can be used to generate a predefined hydraulic pressure hydraulically during the release of…
