Abstract

A method for controlling an electro-hydraulic braking system for motor vehicles, including providing an antilock control function, and a further brake pressure control function which can be activated in a “brake-by-wire” mode. A pressurization device, activated by an electronic control unit can be connected to hydraulically actuated wheel brakes through at least one pressure regulating valve. The pressurization device having a cylinder-piston arrangement with a chamber, the piston of which can be displaced relative to a rest position by an electromechanical actuator. A set pressure value is determined for each wheel brake activating the cylinder-piston arrangement such that a predetermined pre-pressure, which is determined from the set pressure values, is set in the chamber by displacement of the piston.
