Beschreibung
Zusammenfassung:	A multi-axle vehicle equipped with an antilock braking system which provides regulated braking operations to prevent locking of the wheels when the vehicle is braked and spinning of the wheels when the vehicle is started up, comprises a front axle, first and second rear axles, the first rear axle being a drive axle and the second rear axle being a liftable following axle, wheels mounted on each of the axles, rotational speed sensors producing signals indicative of the rotational speeds of the wheels associated with each of the wheels mounted on the front axle, on the drive axle, and on the following axle, brake cylinders associated with each of the wheels, a circuit supplying a pressure medium to the brake cylinders so that a braking pressure is applied to the wheels, and at least one electronic control unit which controls the braking pressure applied to each of the wheels. The vehicle also includes a control valve connected to the electronic control unit which causes the braking pressure applied to the following axle wheels to be greater than the braking pressure applied to the wheels on the drive axle during unregulated, partial braking operation. During regulated braking operations, the braking pressure applied to the following axle wheels is the same as the braking pressure applied to the drive axle wheels.
