BRAKE SYSTEM AND METHOD FOR CONTROLLING A BRAKE PRESSURE

A brake system (100) for a vehicle is disclosed. The vehicle includes at least one axle (10) for which wheel-speed information is not available, and a reference axle (20) for which wheel-speed information is available, the at least one axle (10) includes brake cylinders (11, 12) and a relay valve (15) controllable to provide a target pressure (Pt) to the brake cylinders (11, 12). The brake system (100) comprises an electronic pressure module, EPM, (110) with an output (111) configured to control the relay valve (15) of the at least one axle (10) to provide the target pressure (Pt); andan electronic controller (120) configured control the EPM (110) based on an estimate for the target pressure (Pt), the estimate being derived from data associated with the reference axle (20).
