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.

Abstract: An electric-parking-brake for a utility-vehicle, including: a feed-line for brake-pressure air; a discharge-line for brake-pressure air for a pneumatic-brake-device; a first-valve and a second-valve, each being switchable between a stable-state and an activated-state in response to electrical control-signals; and a valve-device which is connected between the feed-line and the discharge-line and exhibits a control-input, the valve device being switchable between a stable-state and an activated-state in response to control signals at the control-input, the feed-line being connected to the discharge-line in the activated-state, in which the first-valve in the stable-state or in the activated-state connects the control-input of the valve-device to the discharge-line, to retain a current-state of the valve-device when the brake-pressure air is applied to the discharge-line, and in the activated or stable state connects the control-input to the second-valve. Also described are an electric parking brake system, a utility vehicle, and a related method.

Abstract: An ABS pressure control valve assembly for controlling the fluid pressure in a pressure-medium-operated brake system of a vehicle having brake slip control, by which the brake pressure in pressure-medium-operated brake actuators is adaptively adjusted for a locking tendency of individual wheels of the vehicle. Two membranes of two membrane valves are clamped between two housing parts and an intermediate plate. Also described are a pressure-medium-operated brake system of a vehicle with brake-slip control, including at least one such ABS pressure control valve assembly, and to a method for producing such an ABS pressure control valve assembly.

Abstract: A service brake device for vehicles is provided which permits rapid venting of a service brake pressure chamber. The service brake device includes at least one pneumatic service brake device with at least one piston and/or a diaphragm. The piston and/or diaphragm delimits the service brake pressure chamber on one side which can be supplied with compressed air from a brake line for applying the service brake and can be purged of compressed air for releasing the service brake, delimits a spring chamber on the other side which receives a spring that prestresses the piston and/or the diaphragm in the release position of the service brake. The pressure chamber includes a pressure connection communicating with the brake line. A quick air release valve between the brake line and the pressure chamber is arranged to connect the brake line to the pressure chamber when the pressure in the brake chamber is greater than in the pressure chamber, and to connect the pressure chamber to the spring chamber when the pressure in the pressure chamber is greater than the brake line pressure.

Abstract: A method and computer program for electronically regulating the brake force distribution in a pressure medium-operated brake system of a vehicle having at least one front axle brake circuit, associated with a front axle, and at least one rear axle brake circuit, associated with at least one rear axle, in which when the brake system is operated, a rear axle brake pressure, acting in the at least one rear axle brake circuit, is regulated to prevent locking of the rear wheels before locking of the front wheels, and in which the brake pressure at the rear axle is limited only while a pressure value which acts in the rear axle brake circuit is below a prespecified pressure threshold value, but the brake pressure at the rear axle is not limited if the pressure value acting in the rear axle brake circuit is not less than the prespecified pressure threshold value.
