Abstract: Apparatus for controlling dynamics of a vehicle determines a current course angle (?) of the vehicle. A desired course angle (?psi) is defined and assigned to a first point on a temporal profile of a desired driving line. The first point is on the desired driving line at a first preview time from a location assigned to an instantaneous vehicle position. A course angle deviation of the current course angle (?) from the desired course angle (?psi) is determined. A target angle (?ta) is defined and assigned to a second point on the temporal profile of the desired driving line. The second point is on the desired driving line at a distance of a second preview time from the location. A steering wheel angle (?) is determined as a total of the target angle (?ta) reinforced with a first parameter and the course angle deviation reinforced with a second parameter.

Abstract: An inerter device for a wheel suspension of a vehicle, having an inerter mass and a mechanical inerter drive which is operatively connected to the inerter mass via a coupling device. The coupling device has a control disk connected to the inerter mass and a contour disk connected to the inerter drive. The control disk and contour disk are frictionally in contact with each other via coupling surfaces. The inerter mass is reversibly movable relative to the inerter drive from an operating position into a securing position. The control disk has a contact element which, during the movement of the inerter mass into the securing position, interacts with a mating contact element of the contour disk and therefore reversibly moves the control disk from a coupling position relative to the contour disk into a release position in which the coupling surfaces are separated.

Abstract: A screwing tool for an impact wrench for screwing wheel nuts onto and off from a hub body for securing a vehicle wheel, having a main body, which has an open side oriented toward the wheel nuts and which includes a hollow profile. The hollow profile has a tool contour, which is arranged on the open side and can be brought into engagement with a wheel nut contour. At least one peripheral control edge is remote from the open side for releasing a retention element. The control edge has a circular arc region with a constant control edge height h1 and a cam region with a control edge height h2 that decreases continuously and then increases again continuously. Height h1 is equal to h2 in the respective transition of the circular arc region and the cam region, such that the geometrical shape of an oval is reproduced in cross section.
