摘要： An excavation system is disclosed as having a locating device configured to generate a position signal indicative of a position of an excavation machine, a sensor configured to generate a load signal indicative of a work tool status, and a controller. The controller may be configured to determine a location of a haul truck, to determine when the work tool is filled with at least a threshold amount of material from a pile at the worksite, and to determine the position of the excavation machine. The controller may further be configured, based on operating limitations of the excavation machine, to determine a pivot point between the location of the haul truck and the position of the excavation machine; to plan a travel path for the excavation machine to the haul truck through the pivot point; and to direct an operator of the excavation machine to follow the travel path.

摘要： The disclosure relates to a control system for a machine. The control system includes an input unit for obtaining terrain information pertaining to a worksite. The control system further includes a plurality of illumination devices mounted on the machine. The control system further includes a controller in communication with the input unit and the plurality of illumination devices. The controller is configured to receive the terrain information from the input unit. The controller further determines grade pertaining to a work area of the worksite based on the terrain information. The controller is further configured to operate the plurality of illumination devices, based on the grade, to selectively illuminate the work area of the work site.

摘要： A system for controlling an engagement operation between first and second movable machines includes a separation sensor, a relative speed sensor and a controller. The separation sensor determines a separation distance between the first and second machines. The relative speed sensor determines a relative difference in speed between the first and second machines. The controller determines the separation distance between the first and second machines, decelerates the first movable machine when the separation distance is within a deceleration zone, determines a relative difference in speed between the first and second machines, and generates an engagement speed command to operate the first movable machine at a first ground speed equal to a second ground speed of the second movable machine plus a relative engagement speed when the separation distance is within a buffer zone.
