Abstract

A control system utilizes operator satisfaction information for controlling an agricultural harvesting machine having adjustable crop processing structure. The control system includes actuators for controlling the crop processing structure and a controller connected to the actuators and to quality sensor structure. Information for at least one quality parameter of the harvesting process is entered on an operator input device, the entry being dependent on the level of satisfaction the operator perceives concerning the parameter, and the controller controls the actuators based on the operator satisfaction input. The controller stores information about the relationship between the output of the sensor and the satisfaction entry, and this relationship information is used for subsequent control purposes.

Claims

1. A control system for controlling an agricultural harvesting machine having an adjustable crop processor affecting quality parameters of the harvesting process, the control system comprising actuators arranged to control operating parameters of the crop processor, and a controller arranged to automatically control the actuators, characterized in that an operator interface device is connected to the controller to input to the controller an operator input containing information about the level of operator'"'"'s satisfaction with at least one quality parameter of the harvesting process, the level of operator'"'"'s satisfaction including a satisfied level and a dissatisfied level, and wherein the controller is responsive to the level of operator'"'"'s satisfaction to automatically control the actuators based on the operator input.

2. A control system as claimed in claim 1, characterized in that the controller is connected to a memory containing initial operating parameters of the actuators based on information on at least one of actual crop characteristics and harvest conditions.

3. A control system as claimed in claim 2 including a condition sensor, characterized in that the information on at least one of actual crop characteristics and harvest conditions is at least one measured by the condition sensor and inputted to the controller via the operator interface device.

4. A control system as claimed in claim 1, characterized in that the controller is responsive to harvest initiation and receives the level of operator'"'"'s satisfaction with at least one of the quality parameters of the harvesting process after a delay following the harvest initiation.

5. A control system as claimed in claim 1, characterized in that the controller receives the operator input repeatedly until the operator input indicates the satisfied level.

6. A control system as claimed in claim 1, characterized in that the controller stores information on operating parameters of the crop processor and information on correlation between changes in the operating parameters and changes in the quality parameters of the harvesting process.

7. A control system as claimed in claim 1, characterized in that the operator input includes quality information on at least two quality parameters and the controller is responsive to the quality information to control the actuators.

8. A control system as claimed in claim 1, characterized in that the controller is connected to at least one sensor arranged to measure at least one of the quality parameters of the harvesting process and provide a sensor output indicative of the quality parameter measured, and that the controller includes a memory for storing information about the sensor output and related information about the inputted level of operator'"'"'s satisfaction with the quality parameter measured, including whether the satisfied level or the dissatisfied level is indicated for the quality parameter.

9. A control system as claimed in claim 8, characterized in that the memory stores information on the sensor output and the related information about the inputted level of operator'"'"'s satisfaction in dependence on whether the satisfied or dissatisfied level is indicated.

10. A control system as claimed in claim 8, characterized in that the controller is responsive to the sensor output, and to the previously stored information on the sensor output and the related information about the inputted level of operator'"'"'s satisfaction with the quality parameter including whether the satisfied level or the dissatisfied level is indicated for the quality parameter.

11. A control system as claimed in claim 8, characterized in that the memory stores the information about the relationship between the sensor output and the related inputted information about the level of operator'"'"'s satisfaction with the quality parameter together with information on at least one of actual crop characteristics and harvest conditions.

12. A control system as claimed in claim 10, characterized in that the controller is responsive to information on at least one of actual crop characteristics and harvest conditions when the relationship between the output of the sensor and the related inputted information about the operator'"'"'s satisfaction with the quality parameter was recorded, to control the actuators.

13. A method of controlling an agricultural harvesting machine having adjustable crop processing structure affecting quality parameters of the harvesting process, wherein a controller controls actuators influencing operating parameters of the crop processing structure, the method comprising the steps of:

a. providing an operator interface device;

b. inputting operator information for at least one of the quality parameters of the harvesting process to the operator interface device, the step of inputting including providing a satisfaction indication when an operator is satisfied with said at least one of the quality parameters of the harvesting process and providing a dissatisfaction indication when the operator is dissatisfied with said at least one of the quality parameters of the harvesting process; and

c. automatically controlling the actuators with the controller based on the inputted operator information, wherein the step of automatically controlling includes controlling the actuators dependent on whether a satisfaction indication or a dissatisfaction indication is provided.

14. The method as set forth in claim 13 including the step of receiving the operator information at the controller from the operator interface device until the satisfaction indication is provided.

15. The method as set forth in claim 13 including:

providing at least one sensor having an output indicative of one or more of the quality parameters of the harvesting process, and

storing information in the controller about the relationship between the output of the sensor and the associated inputted information about operator satisfaction with the quality parameter.

16. The method as set forth in claim 15 wherein the step of controlling the actuators with the controller includes controlling the actuators based on the output of the sensor and on the information previously stored about the relationship between the output of the sensor and the associated inputted information.

17. The method as set forth in claim 13 wherein the step of providing a dissatisfaction indication includes providing a quality high indication to the controller when one or more of the quality parameters is greater than a first level of quality and providing a quality low indication to the controller when one or more of the quality parameters is less than a second level of quality.
