It is proposed, for an electronic system for operating an electromechanical parking brake device of a vehicle with an input unit for detecting a driver command which is evaluated by a control unit which activates at least one actuating unit for actuating at least one brake, that the control unit consist of at least two control components, of which a first control component is associated with the input unit and at least one second control component is associated with the at least one actuating unit.

Electromechanical parking brake device and electronic system for operating same

The present invention relates to a pressure generator for a hydraulic vehicle brake system for the regulated generation of a hydraulic brake pressure in a brake circuit, the pressure generator having a multiple-piston pump for delivering a brake fluid with at least two pump pistons and associated pressure chambers, on which the pump pistons act, an actuator for actuating the multiple-piston pump, and a fluid feed line which extends to the pressure chambers and is configured for connection to a storage container, in which a hydraulic fluid is stored. At least one valve is arranged in the fluid feed line and divides the latter into a first section which is arranged upstream of the valve and into a second section which is arranged downstream of the valve, the valve being configured to optionally at least partly shut off or open the second section of the fluid feed line and therefore to control the fluid supply of at least one pressure chamber.
