Abstract
Systems and methods for controlling the cross slope of an asphalt paver screed. One system includes a tractor and an implement coupled to the tractor via a left tow arm and a right tow arm. The system also includes a left slope sensor mounted to the left tow arm and a right slope sensor mounted to the right tow arm. The system further includes one or more processors configured to perform operations including receiving left slope data and right slope data, calculating a measured cross slope of a virtual transverse beam extending between the left tow arm and the right tow arm based on the left slope data and the right slope data, obtaining a target cross slope, and causing movement of one or both of the left tow arm and the right tow arm based on a comparison between the measured cross slope and the target cross slope.
