Abstract

A control system for a work machine has an input device operable to receive an input indicative of an operator profile and to generate a signal related to the operator profile. The control system also has a controller in communication with the work machine and the input device. The controller is configured to receive the signal and to change at least one operating parameter of the work machine in response to the signal.

Claims

1. A control system for a work machine, comprising:

an input device operable to receive an input indicative of an operator profile and to generate a signal related to the operator profile;

a controller in communication with the work machine and the input device, the controller configured to receive the signal and to change at least one operating parameter of the work machine in response to the signal.

2. The control system of claim 1, wherein the input device includes a keypad.

3. The control system of claim 1, wherein the input device includes a switch configured to receive an encoded key.

4. The control system of claim 1, wherein the input device includes an antenna configured to receive a remotely transmitted code.

5. The control system of claim 1, wherein the input device includes a data port configured to receive a directly transmitted code.

6. The control system of claim 1, wherein the input device includes a scanner configured to read an encoded indicia.

7. The control system of claim 1, wherein the input device is a biometric device.

8. The control system of claim 1, wherein the operator profile is related to at least one of a skill level, an experience level, and a physical ability of the operator.

9. The control system of claim 1, wherein the operator profile is related to a purchased access level.

10. The control system of claim 1, wherein the at least one operating parameter includes at least one of a work machine travel speed limit, a work machine travel acceleration limit, a work machine torque level limit, and a work machine travel direction limit.

11. The control system of claim 1, wherein the work machine includes a power source, the controller being in communication with the power source, and the at least one operating parameter includes a power source output limit.

12. The control system of claim 1, wherein the work machine includes a transmission, the controller being in communication with the transmission, and the at least one operating parameter includes a transmission output limit.

13. The control system of claim 1, wherein the work machine includes at least one work implement, the controller being in communication with the at least one work implement, and the at least one operating parameter includes a work implement limit.

14. The control system of claim 13, wherein the work implement limit is related to accessibility of the at least one work implement.

15. The control system of claim 1, wherein the controller includes a memory having at least one predetermined profile stored therein, and the controller is configured to change the at least one operating parameter when the operator profile matches the at least one predetermined profile.

16. A method of operating a work machine, comprising

receiving a code indicative of an operator profile with an input device;

generating a signal in response to the code; and

changing at least one operating parameter of the work machine in response to the signal such that the at least one operating parameter falls within a predetermined range related to the operator profile.

17. The method of claim 16, wherein the operator profile is related to at least one of a skill level, an experience level, and a physical ability of the operator.

18. The method of claim 16, wherein the operator profile is related to a purchased access level.

19. The method of claim 16, wherein the work machine includes a power source and changing at least one operating parameter of the work machine includes changing a power source output limit.

20. The method of claim 16, wherein the work machine includes a transmission and changing at least one operating parameter of the work machine includes changing a transmission output limit.

21. The method of claim 16, wherein the work machine includes at least one work implement and changing at least one operating parameter of the work machine includes changing a work implement limit.

22. The method of claim 16, further including changing the at least one operating parameter to a predetermined setting when the signal corresponds to a predetermined profile.

23. A method for limiting work machine functionality, comprising:

assessing a potential operator of the work machine;

creating an operator profile for the potential operator; and

generating a code corresponding to the operator profile, wherein the code is configured for entry into an input device of the work machine.

24. The method of claim 23, further including changing at least one operating parameter of the work machine in response to the code being entered into an input device of the work machine such that the at least one operating parameter falls within a predetermined range related to the operator profile.

25. The method of claim 23, wherein the operator profile is related to at least one of a skill level, an experience level, and a physical ability of the operator.
