Sensor signal processing e.g. for vehicle suspension regulation and=or control - generates correction values from signals related to vehicle movement or inertial reference system to convert from fixed reference system to reference system locked to movement path

摘要

The signal processing system detects a first set of signals (WZ, aL, aQ, aV1, aV2, aV3) representing the vehicle movement relative a fixed reference system and uses them to provide corresponding correction values (betas, betas,', betas"; alphas', alphas"; psis', psis") for the first set of signals, so that they relate to a reference system which is locked to the vehicle movement, e.g. the travel path. Pref. the sensor signals represent the transverse velocity of the vehicle, the longitudinal acceleration, the transverse acceleration and the vertical acceleration. USE/ADVANTAGE - For control or regulation of active vehicle suspension system allowing exact detection of vehicle motion. Corrects for vehicle movements relative to inclined path due to gravitational acceleration components of measured signals.
