Abstract: A system for positioning a working apparatus of a road construction machine, where first and second areas are located forward and rearward, respectively, of the working apparatus. A positioning system includes a controller for changing a position or orientation of the working apparatus. A computer system receives and processes topographical data collected by sensors for points of interest in the first area to generate a first plane equation for a first plane containing at least three of the points of interest. By comparing the first plane equation with an initial position, the computer system determines a second position where the working apparatus can change the road surface from a first state to a second state. The computer system generates instructions for changing a position or orientation of the working apparatus from the initial position to the second position, and the controller executes those instructions.

Abstract: A system for modifying an operational condition, i.e., the discharge speed or position, of a material-handling vehicle (MHV). The system includes a computer utilizing a machine learning engine to analyze visual data, a vision system comprising at least one camera mounted to the MHV for generating said visual data, and a controller operatively connected to the MHV. The vision system generates visual data by imaging an observed area proximate the MHV. That data is transmitted to the computer which, using a processor, analyzes the data to determine if a current operational condition of the MHV is outside of a tolerance band. If it is outside of the band, the computer system generates operational commands to bring the MHV back within the tolerance band and transmits said commands to the controller.
