Abstract
A control system for determining a stale terrain value for use by an autonomous machine is provided. The control system includes a controller associated with the autonomous machine operating on a work surface. The controller is configured to receive position data associated with the autonomous machine from a position sensing system. The controller is configured to receive data related to a dump operation to be performed by the autonomous machine. The data includes a distance between a start location and an end location, a distance between two adjacent piles of material, and an average speed of travel of the autonomous machine. The controller is configured to determine the stale terrain value associated with the work surface. The controller is configured to trigger a control signal for shutting down the dump operation of the autonomous machine on approaching the stale terrain value based on receiving an operator input.
