System for coordinating agricultural vehicle control for loading a truck
First Claim
Patent Images
1. A method for coordinating control of at least one agricultural vehicle for loading a trailer of a truck and trailer combination with a harvested crop material, the method comprising:
- harvesting crop material from a field with a harvester;
directing the harvested crop material towards a grain cart adjacent the harvester;
receiving the harvested crop material into the grain cart towed by a tractor;
moving the grain cart from adjacent the harvester to a position adjacent to a truck and trailer combination defined by an over the road truck towing a trailer for hauling crop material;
initiating a trailer loading sequence;
determining a target total weight value of crop material to load into the trailer based on axle weight ratings of the axles of the truck and trailer combination;
determining a target weight distribution value of the trailer for distributing the crop material in the trailer based on the axle weight ratings of the axles of the truck and trailer combination;
activating a grain cart unloading system for transferring the crop material from the grain cart to the trailer to load the trailer;
controlling the tractor with a tractor controller of a control system to automatically move the tractor relative to the trailer while the grain cart unloading system is activated to load the trailer based on the determined target total weight of crop material and target weight distribution values; and
transferring crop material from the grain cart into the trailer, determining a partial-full condition of the trailer and storing a partial-full value of the trailer in a memory of the control system corresponding to the partial-full condition of the trailer, receiving a subsequent load of harvested crop material and transferring at least some of the crop material from the subsequent load into an area of the trailer based on the stored partial-full value.

Abstract
A system is provided that automatically assesses weight rating characteristics of a truck and trailer combination. The system coordinates movement and unloading functions of the grain cart to automatically load the trailer to correspond to a target total weight value and a target weight distribution value based on axle weight ratings of the axles of the truck and trailer combination.

- 3. The method of claim l wherein the control system identifies the truck and trailer combination and determines the target total weight of crop material and target weight distribution values based on the identified truck and trailer combination.
-
14. The method of claim I further comprising determining an initial fill level of the trailer before beginning transferring the crop material from the grain cart to the trailer and wherein during the determining of the initial fill level of the trailer, the control system moves the tractor relative to the trailer until the partial-full area is detected and wherein the control system commands beginning transfer of the crop material from the grain cart to the trailer at the partial-full area.

17. A method for coordinating control of at least one agricultural vehicle for loading a trailer of a truck and trailer combination with a harvested crop material, the method comprising:
-
harvesting crop material from a field with a harvester; directing the harvested crop material towards a grain cart adjacent the harvester; receiving the harvested crop material into the grain cart towed by a tractor; moving the grain cart from adjacent the harvester to a position adjacent to a truck and trailer combination having axle weight rating values stored in a database corresponding to ratings of axles of the truck and trailer combination; determining a loading path plan based on the axle weight rating values of the truck and trailer combination and a value of at least one of (i) a target total weight value of crop material to load into a trailer of the truck and trailer combination, and (ii) a target weight distribution value of the trailer for distributing the crop material in the trailer; controlling the tractor with a tractor controller to automatically move the tractor relative to a trailer of the truck and trailer combination based on the loading path plan; and transferring crop material from the grain cart into the trailer, determining a partial-full condition of the trailer and storing a partial-full value of the trailer in a memory of the control system corresponding to the partial-full condition of the trailer, receiving a subsequent load of harvested crop material and transferring at least some of the crop material from the subsequent load into an area of the trailer based on the stored partial-full value. - View Dependent Claims (18)

19. A system for coordinating control of at least one agricultural vehicle for loading a trailer of a truck and trailer combination with a harvested crop material harvested by a harvester, the system comprising:
-
a tractor; a grain cart towed by the tractor, the grain cart being adapted for transport between a first position adjacent to a harvester for receiving the harvested crop material from the harvester and a second position adjacent to a truck and trailer combination for unloading the harvested crop material to the truck and trailer combination; a control system including a tractor controller operatively communicating with a grain cart controller for controlling operation of the grain cart, and a truck and trailer identification system for identifying weight rating information of a truck and trailer combination stored in a database accessible by the control system; and a sensor system arranged with respect to at least one of the tractor and grain cart for determining loading status of a trailer of the truck and trailer combination and communicating with the control system for automatically coordinating control of at least one of the tractor and the grain cart for achieving a target total weight value and a target weight distribution value of the truck and trailer combination; wherein the control system is configured to; determine a partial-full condition of the trailer in response to the transferring of the crop material from the grain cart into the trailer; store a partial-full value of the trailer in a memory of the control system corresponding to the partial-full condition of the trailer; broadcast information corresponding to the partial-full condition of the trailer to one or more other grain carts so as to course a subsequent load of harvested crop material to be transferred to an area of trailer based on the stored partial-full value.
