Patent ID: 8294884

Claim:
A sideways drift correction device for a mobile construction machine which includes application of material and a construction tool for processing the applied material, comprising: a sensor component configured for continuous detection of at least a part of the ground surface relative to which the construction machine is moving, the construction machine being moved forward between generated recordings of the ground surface; and an evaluation component configured to recognize a shift of a selected structural feature of the recorded ground surface by comparison of the recordings and for determining therefrom the direction of movement of a reference point of the construction machine relative to the ground, wherein: the sensor component is mounted in a defined orientation relative to a longitudinal axis of the construction machine; and the evaluation component is further configured: to continuously check whether the sensor component is moving only in the direction of the longitudinal axis of the construction machine; to detect a sideways drift of the construction machine on the basis of the determined direction of movement of the reference point relative to the ground; and to derive steering correction information so that the sideways drift is corrected.
