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 (żrel) 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 (żwheel) 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 (żbody) of the vehicle body (10) is calculated by forming a difference of the vertical velocity (żwheel) of wheel (2) and the inward deflection velocity (żrel) of wheel (2).
