  • Publication number: 20240013117
    Abstract: A worksite controller can manage machines, including a first machine configured to perform a first task and a second machine configured to perform a second task that follows the first task. The worksite controller can predict a time that the first machine will complete the first task at a work area. The worksite controller can also predict a time the second machine would arrive at the work area to perform the second task. Based on a comparison of the time the second machine would arrive at the work area and the predicted first task completion time, the worksite controller can instruct the second machine to enter or exit a low-power state. For example, if the second machine would arrive at the work area earlier than the predicted first task completion time, the worksite controller can instruct the second machine to avoid idling while waiting by entering the low-power state.
