Abstract: A system having a controller is provided. The controller receives a signal indicative of an actual position and an actual orientation of a machine on a worksite, from a position detection module. The controller determines a first view of the machine on the worksite. The first view shows the actual position of the machine and a target position of the machine. The controller determines a second view of the machine on the worksite. The second view has a first and a second indicator. The first indicator is indicative of the actual position and the actual orientation of the machine. The second indicator is indicative of the target position and a target orientation of the machine. The controller displays any one of the first view and the second view based, at least in part, on the actual position of the machine relative to the target position on a display unit.

Abstract: A method for assisting a hauling truck to spot a loading position with respect to a loading machine at a worksite includes actuating an implement control unit of loading machine to raise an implement of the loading machine for being identified by the hauling truck. The method further includes receiving at least one parameter associated with the loading position of the hauling truck. The load body of hauling truck is aligned with respect to the raised implement of loading machine in the loading position. The method further includes storing the at least one parameter for loading material from the implement to load body of subsequent hauling trucks, and communicating, via a peer-to-peer communication unit, the at least one stored parameter to subsequent hauling trucks to align the load body of subsequent hauling trucks with respect to the raised implement during subsequent loading operations, until location of loading machine is altered.

Abstract: A truck spotting system is provided that uses a position detection module in a truck and a position detection module in a loader to provide a initial position and orientation of each machine. A perception module on-board the loader is configured to measure a distance and orientation of the truck relative to the loader. A controller receives a initial target position from the truck and calculates a target position from the distance and orientation, then communicates a refined target position to the truck.
