Abstract
A method is provided for controlling a pressure control device of a pressure-medium brake system of a vehicle which individually controls brake pressures in brake cylinders of wheels of an axle. The pressure control device includes a relay valve. In order to compensate for response sluggishness of the relay valve, shut-off valves connected between the relay valve and their respective brake cylinders are not switched into a passage position in which pressure is forwarded to the brake cylinders until a permissible pressure gradient exists between the working pressures of the relay valve and the brake pressures in the brake cylinders.
