Abstract
A method for controlling a pneumatic or electro-pneumatic service brake device of a vehicle is provided. In the method a driver brake request occurs by actuating a service brake actuating element of a service brake valve device of the braking device. In response to actuating the service brake actuating element, at least one control piston of the service brake valve device is loaded with a first actuating force in order to generate a pneumatic brake pressure or brake control pressure in at least one pneumatic service brake circuit of the service brake device. The control piston directly or indirectly controls at least one double-seat valve of the service brake valve device. The at least one double-seat valve includes an inlet seat and an outlet seat. The at least one control piston of the service brake valve device in addition is loaded by a second actuation force additionally or instead of the first actuation force. The second actuation force, which is generated independently of a driver braking request, is applied to the at least one control piston in parallel to the first actuation force, either in the same direction or in the counter direction.
