  • Patent number: 7562946
    Abstract: A brake regulating system particularly suitable for stabilizing the motion of a commercial vehicle is described, in which a control unit outputs, as a function of a number of input variables, a predefined manipulated variable for the brake pressure of each wheel of a commercial vehicle and/or a predefined manipulated variable for an output variable of the drive engine.

  • Patent number: 6729581
    Abstract: A supporting arm of a passenger door of an aircraft, has a curved structure which forms hollow chambers and movably connects the passenger door to a frame on the fuselage. Receiving means one for the supporting arm for receiving connecting means which enable a movable connection on the one hand to the passenger door and a pivoting drive and on the other hand to the frame on the fuselage, so that the door is movable by means of the supporting arm on a linear-displacement path and a pivoting path. The structure of the supporting arm is formed from fiber composite, the structure-forming fiber composite being formed from individual structural elements. This fiber composite structure further improves the thermal insulation of the supporting arm and nevertheless achieves a further weight reduction of the supporting arm, while maintaining exacting structural safety requirements for the latter.

    Abstract: A method for stabilizing a vehicle in particular to prevent overturning, in which a strategy is selected from at least two different strategies as a function of a quantity describing or corresponding to whether an overturn tendency about a vehicle axis oriented in the longitudinal direction of the vehicle exists, and which may be determined at least as a function of a quantity describing or corresponding to the wheel behavior of at least one wheel, and which may also be determined a function of a comparison which is carried out as a function of a quantity describing or corresponding to the lateral dynamics of the vehicle and of a characteristic value that is determined as a function of a quantity describing or corresponding to the instantaneous friction conditions.

  • Patent number: 6324447
    Abstract: A method for stabilizing a vehicle to avoid at least one of a vehicle rolling over about a vehicle axis oriented in the longitudinal direction of the vehicle and the vehicle sliding in the transverse direction. The method determines at least one of a torsion variable that corresponds to how the vehicle behaves in reaction to a force acting on the vehicle about the vehicle axis oriented in the vehicle's longitudinal direction, and a load-shift variable that corresponds to how the vehicle load behaves in reaction to a force acting upon the vehicle. The method determines a vehicle speed and also determines at least one threshold value for the vehicle speed based on the torsion variable and the load-shift variable. The vehicle speed and the at least one threshold value are then compared, and interventions (or measures) are taken to stabilize the vehicle based on the comparison.

  • Patent number: 6272420
    Abstract: A method and an apparatus relate to the detection of a tilt tendency of a vehicle about a vehicle axis oriented in the longitudinal direction of the vehicle. For this purpose, for at least one wheel, a variable describing the wheel rotation speed and at least one variable representing the transverse dynamics of the vehicle are ascertained. As a function of one of the variables representing the transverse dynamics of the vehicle, braking torques and/or drive torques are briefly generated and/or modified at at least one wheel. While the braking torques and/or drive torques at the at least one wheel are being briefly generated and/or modified, and/or after they have been briefly generated and/or modified, a variable which quantitatively describes the wheel behavior is determined for that at least one wheel, as a function of the variable describing the wheel rotation speed of that wheel.

  • Patent number: 6253123
    Abstract: A method for stabilizing a vehicle that avoids one of a vehicle rolling over with respect to a vehicle axis oriented in the longitudinal direction of the vehicle, and the vehicle skidding in a transverse direction. The method determines a vehicle speed and at least two limit values for the vehicle speed, and selects one of the limit values as a reference quantity. In particular, the limit value with the smaller value may be selected as the reference quantity. The method also compares a speed quantity and the reference quantity, and implements measures to stabilize the vehicle based on the comparison. In particular, if the speed quantity is greater than the reference quantity, then the vehicle speed is reduced by intervening in at least one of a retarder operation, an engine operation and a braking operation until the speed quantity is reduced below the reference quantity.

  • Patent number: 6053038
    Abstract: An internal-to-vehicle mechanism for monitoring the air pressure of a tire of a vehicle includes a sensor, detecting the tire pressure, which rotates, together with an electrotechnical first device, synchronously with the wheel and which, as a function of the tire air pressure that is determined, modifies parameters of the first device, namely the energy uptake of the first device. A stationary electrotechnical second device radiates an electric and/or magnetic, in particular electromagnetic, field through which the first device passes at, preferably, each wheel rotation with an uptake of energy from the field. A monitoring device detects the energy uptake and/or energy release of the second device.

  • Patent number: 6021170
    Abstract: A nuclear reactor plant includes a reactor pressure vessel having a core barrel supported on a cylindrical holding structure fixed in the reactor pressure vessel. The core barrel has a lower part with at least one elastically resilient segment. A projection disposed on the segment engages under the holding structure in such a way that a wedge-like gap is formed between a lower surface of the holding structure and the projection. A wedge is braced in the gap. A method is also provided for mounting the core barrel.
