Abstract

A method for monitoring a brake system for motor vehicles. The system can be actuated both by a vehicle driver and independently of the vehicle driver in what is known as a brake-by-wire mode. The hydraulic actuation device can be actuated by means of a brake pedal and has a main brake cylinder to which wheel brakes are connected, at least two brake circuits, a simulation device, which comprises at least one elastic element and gives the vehicle driver a comfortable pedal feeling, an electrically controllable pressure-providing device, which is formed by a cylinder/piston assembly, the piston of which can be actuated by an electromagnetic actuator, wherein the first measurement variable (PDBE) characterizing a position of the piston is detected. The detected measurement value of the first and second measurement variable (SDBE, PDBE) are compared to a predetermined characteristic map of the first and second measurement variables in order to monitor a functional status of the brake system.
