Abstract:
1. A method for controlling an electrohydraulic brake system for motor vehicles, comprising at least one hydraulically actuatable wheel brake ( 9 ) which can be actuated by means of an electronically activatable pressure supply unit ( 16 ) which includes a cylinder-piston arrangement having a hydraulic pressure chamber ( 4 ), and a piston ( 3 ) which is displaceable by an electromechanical actuator ( 1 ), so that a predeterminable pressure reference value (P V,Soll ) is configured to be set in the hydraulic pressure chamber ( 4 ), an actuator position actual value (X Akt ) of a position of the pressure supply unit ( 16 ) being ascertained, a manipulated variable (ω Akt,Soll , M Akt,Soll ) for activating the actuator ( 1 ) generated by means of a control device( 40 ), a position control ( 50 ) of the actuator ( 1 ) being carried out in the control device ( 40 ) on the basis of the actuator position actual value (X Akt ) and of an actuator position reference value (X Mod,Soll ) and the actuator position reference value (X Mod,Soll ) being determined on the basis of the predetermined pressure reference value (P V,Soll ).
