Method and system for operating an electrically controlled pressurized-fluid brake system

A method for operating an electrically controlled pressurized-fluid vehicle brake system having at least one brake, at least one brake cylinder actuatable by pressurized fluid for actuating said at least one brake, at least one braking-pressure sensor for obtaining braking-pressure data representing braking pressure in said at least one brake cylinder, at least one valve device for influencing said braking pressure, said at least one brake cylinder in communication via said at least one valve device with at least one of a supply pressure and a set pressure in order to feed pressurized fluid, and at least one set-pressure sensor for obtaining set pressure data representing said set pressure, said braking pressure being adjusted based on at least one of said set-pressure data and said braking-pressure data, the method comprising the steps of checking said set-pressure data by temporarily switching pressurized-fluid feed to said brake cylinder from said supply pressure to said set pressure by actuation of at least one part of said at least one valve device, and monitoring resulting braking pressure on the basis of said braking-pressure data.
