  • Patent number: 10704213
    Abstract: The present invention relates to a method for controlling a height adjustment of a stripping plate of a ground milling machine, in particular a stripping plate of a cold milling machine, during the working process, said method comprising the following steps of detecting the striking of the stripping plate against an obstacle; automatically triggering the height adjustment unit for lifting the stripping plate from a working position, in which the stripping plate is in contact with the underlying ground to be processed, to avoid a further collision with the obstacle; and automatically triggering the height adjustment unit for lowering the stripping plate back to the working position upon overcoming the obstacle.

  • Patent number: 10676879
    Abstract: A method for monitoring the compaction process of an asphalt layer to be compacted in road construction is provided comprising the steps: detecting the edges limiting the hot asphalt layer transversely to the road pathway by means of a temperature sensor arranged on a road roller compacting the asphalt layer, and dividing the detected asphalt layer into at least two width segments across the road pathway, wherein the position of the road roller on the asphalt layer transversely to the road pathway is determined from the measurement of the temperature sensor and is assigned to one of the width segments, the working operation of the road roller on the width segment is quantified via an operating parameter and stored, and the quantified working operation for each width segment is displayed to the operator for at least one past working interval. A road roller for carrying out the method is also provided.
