System and method for determining implement train position
First Claim
1. A method for determining a location or heading of one or more fiducials of a trailing vehicle in an implement train based on information about a rear hitch of a leading vehicle of the implement train, the method comprising:
- identifying, using a leading vehicle position sensor, a destination location for a rear hitch of a leading vehicle in the implement train;
identifying, using a processor circuit, a first location and a first heading of a trailing vehicle in the implement train;
determining, using the processor circuit, a destination heading of the trailing vehicle when the rear hitch of the leading vehicle coincides with a front hitch of the trailing vehicle and the destination location, wherein determining the destination heading includes;
identifying a linear distance between the first location of the trailing vehicle and the destination location for the rear hitch of the leading vehicle,determining an intermediate location ahead of the first location of the trailing vehicle by less than the linear distance and in the direction of the first heading of the trailing vehicle, anddetermining the destination heading of the trailing vehicle, the destination heading corresponding to a direction of a shortest path from the intermediate location to the destination location; and
using the destination location for the rear hitch and the destination heading of the trailing vehicle, using the processor circuit for determining a location of a first implement on the trailing vehicle in the implement train.

Abstract
Leading vehicle position information can be used to determine a location and heading of one or more implements of a trailing vehicle in an implement train that includes the leading vehicle. In an example, the leading vehicle pulls one or more trailing vehicles, and information about the leading vehicle position or heading is used to update a function of one or more implements associated with trailing vehicles of the implement train. In an example, the present subject matter includes identifying a heading of a trailing vehicle based on its initial location, an intermediate location, and a destination location. In an example, the present subject matter includes identifying a speed of one or more points on a trailing vehicle. In some examples, the present subject matter includes determining a location, heading, or speed of multiple implements associated with multiple trailing vehicles.

9. A non-transitory massed machine-readable medium (MMRM) including instructions that, when executed by a machine, cause the machine to perform operations comprising:
-
identifying a destination location of a leading vehicle fiducial of a leading vehicle, the leading vehicle fiducial coincident with a first fiducial of a first trailing vehicle of an implement train, the identifying the destination location including sensing the destination location using a leading vehicle position sensor that is coupled to the leading vehicle; identifying an initial heading corresponding to the first fiducial and a second fiducial of the first trailing vehicle when the second fiducial coincides with an initial location; determining a heading of the first and second fiducials of the first trailing vehicle when the first fiducial coincides with the destination location, determining the heading of the first and second fiducials including; identifying a linear distance between the destination location of the leading vehicle fiducial and the initial location, and determining an intermediate location based on the linear distance and the initial heading, the intermediate location between the initial location and the destination location; and determining a location and heading of a third fiducial of the first trailing vehicle, based on the heading of the first and second fiducials when the first fiducial coincides with the destination location of the leading vehicle fiducial. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A system for determining a position of a first agricultural implement that is on-board a first trailing vehicle of an implement train, the implement train pulled by a leading vehicle, the system comprising:
-
a processor circuit that is on-board the leading vehicle; a positioning system receiver that is on-board the leading vehicle; and a non-transitory tangible processor-readable medium, coupled to the processor circuit, comprising instructions that, when executed by the processor circuit, cause the processor circuit to; receive information about a distance between an initial location of a first trailing vehicle fiducial and a destination location of the first trailing vehicle, the destination location determined using position information that is received using the positioning system receiver; determine a heading of the first trailing vehicle fiducial when the first trailing vehicle is at the destination location, the heading of the first trailing vehicle fiducial based on an intermediate location between the initial location and the destination location; and provide a control signal to the first agricultural implement based on the determined heading of the first trailing vehicle fiducial, the control signal usable by the first agricultural implement to update a function of the first agricultural implement; wherein the first trailing vehicle fiducial corresponds to an articulating joint where a rear hitch of the leading vehicle is coupled to the first trailing vehicle. - View Dependent Claims (19, 20)
