First Claim
Patent Images
1. An agricultural vehicle, comprising:
- a plurality of actuators configured to control at least one system for turning the agricultural vehicle;
a spatial locating system;
one or more speed sensors;
one or more measurement devices; and
an automatic guidance system configured to navigate the agricultural vehicle, wherein the automatic guidance system comprises;
a receiver component configured to receive a first set of data from at least one of the spatial locating system, the one or more speed sensors, or the one or more measurement devices;
a calculation component configured to calculate a second set of data based on the first set of data;
a decision component configured to;
determine whether one of or both of a steering angle of the agricultural vehicle and a speed of the agricultural vehicle should be adjusted based on the first and second sets of data;
in response to a determination that one of the steering angle or speed of the agricultural vehicle should be adjusted, adjust the steering angle or speed of the agricultural vehicle, respectively; and
in response to a determination that both of the steering angle and speed of the agricultural vehicle should be adjusted, select a preferred vehicle action between adjusting the steering angle of the agricultural vehicle and adjusting the speed of the agricultural vehicle given the first and second sets of data; and
an actuation component configured to control the plurality of actuators to adjust the vehicle speed or steering angle of the agricultural vehicle in response to the decision component.

Abstract
A non-transitory computer-readable medium may store computer executable code. The computer executable code may include instructions to identify a turn to be taken by an agricultural vehicle and to receive a first set of data from at least one of a spatial locating system, one or more speed sensors, and one or more measurement devices. The computer executable code may also include instructions to calculate a second set of data based upon the first set of data. Further, the computer executable code may include instructions to select a vehicle action in anticipation of the turn, based on the first and second sets of data and to control a plurality of actuators to perform the vehicle action.

12. A non-transitory computer-readable medium storing computer executable code that when executed by at least one processor of an automatic guidance system of an agricultural vehicle causes the automatic guidance system to:
-
identify a turn to be taken by the agricultural vehicle; receive a first set of data from at least one of a spatial locating system, one or more speed sensors, and one or more measurement devices; calculate a second set of data based upon the first set of data; determine, via the automatic guidance system, whether one of or both of a steering angle of the agricultural vehicle and a speed of the agricultural vehicle should be adjusted based on the first and second sets of data; in response to a determination that one of the steering angle or speed of the agricultural vehicle should be adjusted, adjust the steering angle or speed of the agricultural vehicle, respectively; in response to a determination that both of the steering angle and speed of the agricultural vehicle should be adjusted, select a preferred vehicle action between adjusting the steering angle of the agricultural vehicle and adjusting the speed of the agricultural vehicle given the first and second sets of data; control a plurality of actuators to adjust the vehicle speed or steering angle of the agricultural vehicle in response to the decision component. - View Dependent Claims (13, 14)

15. A method for controlling an automatic guidance system of an agricultural vehicle, comprising:
-
identifying, via the automatic guidance system, a turn to be taken by the agricultural vehicle; receiving, via the automatic guidance system, a first set of data from at least one of a spatial locating system, one or more speed sensors, and one or more measurement devices; calculating, via the automatic guidance system, a second set of data based upon the first set of data; determining, via the automatic guidance system, whether one of or both of a steering angle of the agricultural vehicle and a speed of the agricultural vehicle should be adjusted based on the first and second sets of data; in response to a determination that one of the steering angle or speed of the agricultural vehicle should be adjusted, adjusting the steering angle or speed of the agricultural vehicle, respectively; in response to a determination that both of the steering angle and speed of the agricultural vehicle should be adjusted, selecting a preferred vehicle action between adjusting the steering angle of the agricultural vehicle and adjusting the speed of the agricultural vehicle given the first and second sets of data; controlling, via the automatic guidance system, a plurality of actuators to adjust the vehicle speed or steering angle of the agricultural vehicle in response to the decision component.
