    摘要： A method is for the leak-tightness and operational testing of a stop valve of a pneumatic suspension of a motor vehicle with gas springs, with at least in each case one active volume capable of being connected via the stop valve, the vehicle including at least one connectable pressure source, at least one connectable pressure sink and, for each axle, at least one measuring device determining the distance to the vehicle body, and also damping elements limiting the stroke of the respective gas spring. For this purpose, in a first step, with the stop valve open, a stroke, during which at least one damping element is compressed, is set on the individual gas spring. In a second step, after the closing of the stop valve, the individual gas spring is set to a part-stroke of its total stroke between the damping elements. In a third step, after the opening of the stop valve, the distance which is established between the axle and the vehicle body is determined with the aid of the measuring device and is compared with a predetermined desired value. Thus, a method for leak-tightness and operational testing is provided, which is performed, without the dismantling of components, by the devices already present in the vehicle.

    摘要： The intention is to specify a simplified design for a device which is used in vehicles for determining a vertical distance between a vehicle body and at least one vehicle wheel which is adjustably mounted thereon. In the device according to the invention, a first inclination sensor which generates first inclination signals which are correlated to the inclination of the vehicle body with respect to a reference position, and transmits them to a control unit, is attached to the vehicle body. Attached to a coupling component which is adjusted, together with the vehicle wheel, relative to the vehicle body, is a second inclination sensor which generates second inclination signals which are correlated to the inclination of this coupling component with respect to a reference position, and transmits them to the control unit. The control unit then determines from the inclination signals of the inclination sensors a distance signal which is correlated to the vertical distance between the vehicle wheel and the vehicle body.

    摘要： It is proposed that a pneumatic suspension leveling system for vehicles with pneumatic suspension leveling elements assigned to the vehicle axles and/or vehicle wheels, with a compressor and a central pressure accumulator fed by it for the compressed air supply of the pneumatic suspension leveling elements, with an accumulator pressure sensor which detects the air pressure in the central pressure accumulator and generates a signal value correlating thereto, and with an electronic control device which processes the signal values of the central pressure accumulator and induces a pressure charging of the central pressure accumulator by the compressor, when the signal value of the accumulator pressure sensor reaches a predetermined lower threshold signal value and terminates this pressure charging when the signal value of the accumulator pressure sensor reaches a preset upper threshold signal value be improved with respect to its functional capacity. This is achieved by providing an ambient pressure sensor which detects the air pressure in the atmosphere surrounding the vehicle and generates a signal value correlating thereto, whereby the control device processes the signal values of the ambient pressure sensor and varies the upper threshold signal value in function thereof.

    摘要： In a method for controlling the ride height of a wheeled vehicle, the distance between a vehicle body and a wheel suspension unit for at least one wheel provided with a gas-filled tire is adjusted to a distance setpoint value which can be predefined in a variable fashion at least as a function of the vehicle payload. The tire pressure is sensed and the distance setpoint value is additionally predefined in a variable fashion as a function of the sensed tire pressure. For this purpose, in the wheeled vehicle, the tire is assigned a tire-pressure sensor, and the distance setpoint value can additionally be predefined in a variable fashion as a function of the sensed tire pressure.

    摘要： In a vehicle having wheels with inflatable tires, position generators are assigned to each wheel to detect the distances between the wheel and the vehicle body. It is determined whether the time related mean wheel centers are situated approximately in a common plane. If not, a warning signal is generated, indicating defective tire air pressure.
