Abstract
A method for controlling a motor vehicle electrohydraulic braking system. The method being activatable in a “brake-by-wire” operating mode, having a pressure supply device (2), which can be activated by an electronic control and a regulation unit, can be connected to a hydraulically actuatable wheel brake. Wherein the pressure supply device (2) is formed by a cylinder-piston assembly (43). The piston (45) can be actuated by an electromechanical actuator (44), the control unit carries out the steps of determining a pressure target value (PV,Soll) for the pressure supply device (2), performing a pressure control operation or an actuator position control operation on the pressure supply device (2) in accordance with the magnitude of the pressure target value (PV,Soll).
