The present disclosure relates to a control system for a road paver. The control system comprises a camera system configured to generate image data of an environment of the road paver. The control system further comprises a controller electronically connected to the camera system. The controller is configured to receive the image data from the camera system, and to apply an object recognition process on the received image data to identify an edge line serving as a reference line for a mat to be laid by the road paver, and to determine a three dimensional position of the identified edge line. The controller may automatically control the road paver, and may assist an operator to control the road paver based on the identified position of the edge line.

A slip form paving machine includes a machine frame (10), a plurality of ground engaging wheels or tracks (30,30F,30R) and front and rear height adjustable lifting columns (32,32F,32R) supporting the machine frame from the ground engaging wheels or tracks, the lifting columns being adjustable to adjust a longitudinal inclination of the machine frame in a paving direction (12). A slip form mold (24) is supported from the machine frame for molding a mass of concrete (16A) into a formed not yet hardened concrete slab as the paving machine moves forward in the paving direction. A swelling sensor (220) is arranged to detect a swelling of the formed not yet hardened concrete slab relative to the machine frame behind the slip form mold. A method of controlling the slip form paving machine is also disclosed.
