Abstract: Non-line of sight (NLOS) remote control for machines is accomplished by a remote-control station with cellular connectivity to run multiple machines remotely. However, NLOS is expensive and may not work in areas with low cell tower coverage. Accordingly, the present disclosure pertains to providing on-machine remote control to operators of machines at a worksite. The on-machine remote control allows one machine to actively control another machine through connectivity between those two machines. For example, a tractor operator may use on-machine remote control to take control of a compactor, such that the compactor may be run using the tractor controls.

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.
