Patent ID: 8079776

Claim:
A paver for the paving of ground courses for roads or the like, comprising: a chassis having right and left sides, a trailed floating screed which is articulated at tow points on the chassis by tow arms and has an angle of attack relative to the ground that can be adjusted by an actuating cylinder, arranged on each of the sides of the chassis, for displacing the tow point of the tow arms, a tow-point displacement controller for each side that generates a displacement actuation signal to the actuating cylinder for setting the tow point corresponding to an intended paving height dimension of the screed for each side, displacement sensors for measuring the displacement movements of the actuating cylinders, a control unit coupled to the displacement sensors, which records the displacement movements as control values and compares them with a nominal control value range for displacement movements that can be stored in the control unit and corrects recorded control values outside the nominal control value range to values within the nominal control value range by amending the displacement actuation signals from the tow-point displacement controllers to the actuating cylinders; wherein the control unit corrects incorrect settings of tow points of the actuating cylinders by monitoring the displacement movements for plausibility.
