Abstract: A system for surface data management for a machine is provided. A first controller maintains an updated surface data and an updating time. A second controller maintains a surface data and a recording time. The second controller transmits a time request for the updating time associated with a destination location. The second controller receives the updating time associated with the destination location. The second controller is compares the updating time with the recording time, each associated with the destination location. If the updating time is more recent than the recording time, the second controller transmits a data request for the updated surface data associated with the destination location and receives the updated surface data. The second controller compares the updated surface data with the surface data, each associated with the destination location and determines a change in the surface data associated with the destination location based on the comparison.

Abstract: A system for autonomously controlling a fluid refill station (FRS) includes a sensor that generates an input signal indicative of an amount of fluid in a tank of an autonomous truck and a central controller. The central controller monitors the amount of fluid in the tank and assigns the autonomous truck to the FRS if the amount of fluid has reached a minimum threshold value. The central controller determines an alignment of the tank of the autonomous truck with a fluid outlet of the FRS, directs the FRS to refill the tank with fluid if the tank is in alignment with the fluid outlet of the FRS, and directs the FRS to stop refilling the tank when the amount of fluid in the tank has reached a maximum threshold value. The central controller marks the FRS as non-functional based on a determination of an anomaly with the FRS.
