Publication number: 20230094845Abstract: 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.Type: ApplicationFiled: September 29, 2021Publication date: March 30, 2023Applicant: Caterpillar Paving Products Inc.Inventors: John L.
