METHOD FOR DETERMINING AT LEAST ONE DISPLACEMENT STATE OF A VEHICLE BODY

摘要

The invention relates to a method for determining at least one displacement state of a body (10) of a vehicle (1), comprising at least one wheel (2) which is spring-mounted on the vehicle body by means of a wheel suspension (6). According to the invention, a spring deflection (z_rel) of the wheel (2) is measured by means of a path or angle sensor (21); a spring deflection speed (z_rel) of the wheel (2) is determined by temporal differentiation of the spring deflection (z_rel) of the wheel (2); a vertical acceleration (z_rel) of the wheel (2) is measured by means of an acceleration sensor (22); a vertical speed (z_RAD) of the wheel (2) is determined by temporal integration of the vertical acceleration (z_RAD) of the wheel (2); and a vertical speed (z_AUFB) of the vehicle body (10) is calculated by forming a difference between the vertical speed (z_RAD) and the spring deflection speed (z_rel) of the wheel (2).
