System and method for determining implement train position

摘要

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.

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.
