Patent ID: 8788172

Claim:
A method for controlling an electro-hydraulic braking system for motor vehicles, comprising providing at least one first closed or open-loop brake pressure control function including an antilock control function, and a second closed or open-loop brake pressure control function, which can be activated in a “brake-by-wire” operating mode, and providing a pressurization device ( 50 ), which can be activated by means of an electronic control unit and which is or can be connected to hydraulically actuated wheel brakes ( 9 ) and by means of which the wheel brakes ( 9 ) can be hydraulically actuated by way of at least one pressure regulating valve ( 6 ), wherein the pressurization device is provided in a form having a cylinder-piston arrangement having a hydraulic pressure chamber ( 4 ), the piston ( 3 ) of which arrangement can be displaced relative to a rest position ( 15 , 111 ) by an electromechanical actuator ( 1 , 2 ), determining a set pressure value (P Request — i ) for each wheel brake ( 9 ), activating the cylinder-piston arrangement ( 3 , 4 ) in such a way that a predetermined pre-pressure (P Pre — Pressure ), which is determined from the set pressure values (P Request — i ), is set in the hydraulic pressure chamber ( 4 ) by displacement (s) of the piston ( 3 ), and selecting the pre-pressure (P Pre — Pressure ) as the largest of the set pressure values (P Request — i ).
