Abstract: A pulsation damper for damping pressure medium vibrations in a hydraulic system, has a membrane within a bore of a housing, which membrane is exposed to the pressure medium on its one side and faces a gas-filled cavity inside the housing on its other side, the bore of which is closed by means of a plug. The membrane, in conjunction with the plug and a hollow-cylindrical support body, forms an independently handleable, functionally pre-testable assembly, for which purpose the membrane is substantially cup-shaped, and the support body extends into it.

Abstract: A method for adapting the comfort of a vehicle for a vehicle user. The vehicle has an HMI system with which the user and vehicle interact. A suspension system adapts a position of the user to a roadway. A position planning device plans and regulates movement of the vehicle. A regulating device, which has a memory, is connected to the HMI and a suspension system and the position planning device. According to the method, a target comfort zone for the user is stored in the regulating device memory. A current comfort zone of the user is continuously determined, via the HMI system, and continuously compared with the target comfort zone. Based on comparison results, the regulating device controls the suspension system, the position of the user being adapted to the roadway such that the current comfort zone continues approaching the target comfort zone until the target comfort zone is reached.

The holding and connecting devices and the transverse spring are designed such that when the transverse spring is in its installed position a cross-sectional plane of the transverse spring, that extends in the vertical and longitudinal directions of the vehicle, can pivot in the area of the mounting fixture during jouncing and rebound of the transverse spring, about a rotational axis that extends in the longitudinal direction. The holding and connecting devices, in the area of the mounting fixture, are designed such that the rotational axis of the cross-sectional plane of the transverse spring is vertically spaced from the neutral fiber of the transverse spring.

Abstract: A method for determining a maximum adhesion limit between a tire and a substrate on which the tire is running in a longitudinal direction. The method includes detecting an instantaneous slip of the tire; detecting an instantaneous longitudinal force on the tire; determining an instantaneous coefficient of adhesion; forming a tuple from the detected slip and determined instantaneous coefficient of adhesion; and determining the adhesion limit. The adhesion limit is determined on the basis of the slope of a straight line passing through the origin and the tuple, if the slip is less than a first threshold value, or on the basis of the slope of a tangent passing through the tuple, if the slip is between the first threshold value and a second threshold value, or directly on the basis of the instantaneous coefficient of adhesion, if the slip is greater than the second threshold value.

Abstract: A method for determining a safe speed (v*) at a future waypoint (s*) of a vehicle moving along a route. In this step, at least one item of route data (in particular the curvature of the curve ?) characterizing the course of the route is determined. In addition, a first probability distribution (Pges) of a coefficient of friction (?) is provided at the current waypoint (s) and/or at the future waypoint (s*) of the vehicle. Subsequently a second probability distribution (Pv) of a vehicle speed (v) at the future waypoint (s*) is determined from the at least one item of route data (?) and from the first probability distribution (Pges). The safe speed (v*) is determined by statistical analysis from the second probability distribution (Pv).
