Abstract

One agricultural system includes a hitch assembly configured to couple an agricultural vehicle with an agricultural implement. The agricultural system also includes a sensor coupled to the hitch assembly and configured to provide a signal indicative of a force applied to the hitch assembly by the agricultural vehicle and/or the agricultural implement. The agricultural system includes control circuitry configured to receive the signal from the sensor, to select a parameter associated with operation of the agricultural vehicle and/or the agricultural implement, based on the signal, to determine if performance of the agricultural vehicle and/or the agricultural implement will be improved by adjusting the parameter, and to control the parameter if performance of the agricultural vehicle and/or the agricultural implement will be improved.

Claims

a hitch assembly configured to couple an agricultural vehicle with an agricultural implement;

a sensor coupled to the hitch assembly and configured to provide a signal indicative of a force applied to the hitch assembly by the agricultural vehicle, the agricultural implement, or some combination thereof; and

control circuitry configured to receive the signal from the sensor, to select one parameter from a plurality of parameters associated with operation of the agricultural vehicle, the agricultural implement, or some combination thereof, based at least in part on the signal, to determine if performance of the agricultural vehicle, the agricultural implement, or some combination thereof, will be improved by adjusting the one parameter selected from the plurality of parameters, and to control the one parameter selected from the plurality of parameters if performance of the agricultural vehicle, the agricultural implement, or some combination thereof, will be improved;

wherein the plurality of parameters comprises a speed of the agricultural vehicle, a speed of the agricultural implement, a braking force of the agricultural vehicle, a braking force of the agricultural implement, an engine speed of the agricultural vehicle, a depth of a ground engaging tool of the agricultural implement, a hydraulic force applied by a hydraulic system, a gear ratio of a transmission of the agricultural vehicle, or a combination thereof.

2. The agricultural system of claim 1, wherein the hitch assembly comprises a drawbar, and the sensor is coupled to the drawbar of the hitch assembly.

3. The agricultural system of claim 1, wherein the sensor comprises a strain gauge, a load cell, or some combination thereof.

4. An agricultural system comprising:

an agricultural vehicle comprising a hitch assembly configured to be coupled to an agricultural implement, a sensor coupled to the hitch assembly and configured to provide a signal indicative of a force applied to the hitch assembly by the agricultural implement, and control circuitry configured to receive the signal from the sensor;

wherein the control circuitry is configured to select one parameter from a plurality of parameters associated with operation of the agricultural vehicle, the agricultural implement, or some combination thereof, based at least in part on the signal, to determine if performance of the agricultural vehicle, the agricultural implement, or some combination thereof, will be improved by adjusting the one parameter selected from the plurality of parameters, and to control the one parameter selected from the plurality of parameters if performance of the agricultural vehicle, the agricultural implement, or some combination thereof, will be improved; and

wherein the plurality of parameters comprises a speed of the agricultural vehicle, a speed of the agricultural implement, a braking force of the agricultural vehicle, a braking force of the agricultural implement, an engine speed of the agricultural vehicle, a depth of a ground engaging tool of the agricultural implement, a hydraulic force applied by a hydraulic system, a gear ratio of a transmission of the agricultural vehicle, or a combination thereof.

5. The agricultural system of claim 4, wherein the hitch assembly comprises a drawbar, and the sensor is coupled to the drawbar of the hitch assembly.

6. The agricultural system of claim 4, wherein the sensor comprises a strain gauge, a load cell, or some combination thereof.

sensing a force applied by an agricultural implement to a hitch assembly of the agricultural vehicle using a sensor;

selecting one parameter from a plurality of parameters associated with operation of the agricultural vehicle, the agricultural implement, or some combination thereof, based at least in part on the sensed force and using control circuitry;

determining if performance of the agricultural vehicle, the agricultural implement, or some combination thereof, will be improved by adjusting the one parameter selected from the plurality of parameters using the control circuitry; and

controlling the one parameter selected from the plurality of parameters using the control circuitry if performance of the agricultural vehicle, the agricultural implement, or some combination thereof, will be improved;

wherein the plurality of parameters comprises a speed of the agricultural vehicle, a speed of the agricultural implement, a braking force of the agricultural vehicle, a braking force of the agricultural implement, an engine speed of the agricultural vehicle, a depth of a ground engaging tool of the agricultural implement, a hydraulic force applied by a hydraulic system, a gear ratio of a transmission of the agricultural vehicle, or a combination thereof.

8. The method of claim 7, wherein determining if performance of the agricultural vehicle, the agricultural implement, or some combination thereof, will be improved by adjusting the one parameter selected from the plurality of parameters comprises determining a current fuel efficiency based on a current value of the selected parameter, adjusting the selected parameter to an adjusted value, determining a projected fuel efficiency based on the adjusted value of the selected parameter, and comparing the projected fuel efficiency to the current fuel efficiency.

9. The method of claim 7, wherein determining if performance of the agricultural vehicle, the agricultural implement, or some combination thereof, will be improved by adjusting the one parameter selected from the plurality of parameters comprises determining a current cost of operating the agricultural vehicle, the agricultural implement, or some combination thereof, based on a current value of the selected parameter, adjusting the selected parameter to an adjusted value, determining a projected cost of operating the agricultural vehicle, the agricultural implement, or some combination thereof, based on the adjusted value of the selected parameter, and comparing the projected cost of operating the agricultural vehicle, the agricultural implement, or some combination thereof, to the current cost of operating the agricultural vehicle, the agricultural implement, or some combination thereof.

10. The method of claim 7, wherein controlling the one parameter selected from the plurality of parameters comprises at least one of increasing the engine speed of the agricultural vehicle, decreasing the engine speed, increasing engine braking, reducing engine braking, engaging a four wheel drive system of the agricultural vehicle, disengaging the four wheel drive system, and changing the gear ratio of the transmission of the agricultural vehicle.
