Abstract
A hitch point where a receiving vehicle is coupled to a following vehicle is located relative to a leading vehicle. The trajectory or route of the following vehicle is detected and a dynamic model estimates a location of a receiving area in the receiving vehicle relative to the leading vehicle based on the trajectory or route of the following vehicle and the location of the hitch point relative to the leading vehicle.
Claims19
A computer implemented method of controlling an unloading operation for unloading material from a leading vehicle to a receiving vehicle that is propelled by a following vehicle, the method comprising:
- detecting a hitch point location indicative of a relative location of a hitch point relative to the leading vehicle, wherein the receiving vehicle is coupled to the following vehicle at the hitch point;
- identifying a route of the following vehicle;
- determining, with a dynamic model, a location of the receiving vehicle relative to the leading vehicle based on the route of the following vehicle and based on the hitch point location indicative of the relative location of the hitch point relative to the leading vehicle;
- and
- controlling the unloading operation based on the location of the receiving vehicle relative to the leading vehicle.
A work machine system including a leading vehicle configured to unload material into a receiving vehicle during an unloading operation, the receiving vehicle being propelled by a following vehicle, the work machine system comprising:
- a following vehicle route detection system configured to identify a route of the following vehicle;
- a hitch point location system configured to detect a hitch point location indicative of a relative location of a hitch point relative to the leading vehicle, wherein the receiving vehicle is coupled to the following vehicle at the hitch point;
- a dynamic model configured to determine a location of the receiving vehicle relative to the leading vehicle based on the route of the following vehicle and based on the hitch point location indicative of the relative location of the hitch point relative to the leading vehicle;
- and
- a control system configured to control the unloading operation based on the location of the receiving vehicle relative to the leading vehicle.
