摘要： The disclosure relates to a fluid valve including a lip seal having a sealing lip between a pressure inlet and a pressure outlet, wherein the position of the sealing lip can be varied to vary a passage cross section. The disclosure further relates to a pneumatic valve arrangement having a park release valve and the fluid valve. The disclosure further relates to a pneumatic braking system including the fluid valve or the pneumatic valve arrangement.

摘要： An antilock control method for a braking system of a vehicle has at least the following steps: upon the presence of a brake request signal, outputting a brake control signal and building up a brake pressure by a braking medium at a wheel brake of a vehicle wheel, measuring a wheel speed of the vehicle wheel to be braked, and determining a wheel slip of the vehicle wheel, upon meeting a first traction criterion or a locking tendency of the vehicle wheel, activating a wheel drive unit and applying a wheel drive torque on the vehicle wheel to increase the wheel circumferential velocity and to reduce the wheel slip until a second traction criterion is met. The brake force introduced in the wheel brake is controlled as a function of the wheel slip by releasing the brake pressure upon satisfying a first traction criterion.
