  • Patent number: 8428807
    Abstract: Process for determining at least one state of motion of a vehicle body (10) of a vehicle (1), which has at least one wheel (2) spring-mounted on the vehicle body (10) via a wheel suspension (6), wherein an inward deflection (zrel) of the wheel (2) is measured by means of a path or angle sensor (21), an inward deflection velocity (?rel) of the wheel (2) is determined by differentiating the inward deflection (zrel) of the wheel (2) over time, a vertical acceleration ({umlaut over (z)}wheel) of the wheel (2) is measured by means of an acceleration sensor (22), a vertical velocity (?wheel) of the wheel (2) is determined by integrating the vertical acceleration ({umlaut over (z)}wheel) of the wheel (2) over time, and a vertical velocity (?body) of the vehicle body (10) is calculated by forming a difference of the vertical velocity (?wheel) of wheel (2) and the inward deflection velocity (?rel) of wheel (2).

  • Patent number: 7013206
    Abstract: One or several vibration dampers of a vehicle suspension have a damping force arrangement wherein a control signal is computed within the actuating range in accordance with a standard control method for adjusting the damper characteristic. The drive of a damper adjustable in accordance with this invention is so improved that body movements (notwithstanding a harder adjusted damping for critical driving situations) are substantially suppressed as early as possible. In specific driving situations, the adjusting range of the damper force is changed in that the upper limit of the adjusting range is raised or lowered and/or the lower limit of the adjusting range is raised or lowered. A soft damper setting takes place preferably in dependence upon signals which announce or display a change of the vehicle longitudinal deceleration or vehicle transverse acceleration.
