Abstract

In a self-propelled agricultural working machine having working units whose working parameters are adjustable, moving at a ground speed that is regulated automatically as a function of at least one crop-material parameter and/or one working parameter of the working machine using a forward-travel regulator, and having at least one control, operating, and display unit, with which the crop-material parameters and/or the working parameters of the working machine may be adjusted and displayed, the operator of the working machine has access to information regarding the state of the forward-travel regulator when the ground speed is being regulated using a forward-travel regulator. For this purpose, the crop-material parameter and/or working parameter of the working machine that currently limits the ground-speed control via the forward-travel regulator is displayed directly to the operator of the working machine in the control, operating, and display unit.

Claims

1. A self-propelled agricultural working machine, comprising working units with adjustable working parameters;

a forward-travel regulator for regulating a ground speed of the working machine automatically as a function of at least one parameter selected from the group consisting of a crop-material parameter, a working parameter of the working machine, and both;

at least one control, operating, and display unit with which said at least one parameter is adjustable, configured such that said at least one parameter that currently limits a ground-speed control via said forward-travel regulator is displayed directly to an operator of the working machine in said control, operating, and display unit.

2. A self-propelled agricultural working machine as defined in claim 1, wherein said control, operating and display unit is configured so that said at least one parameter that currently limits the ground-speed control via said forward-travel regulator is displayed as a pictogram in said control, operating, and display unit.

3. A self-propelled agricultural working machine as defined in claim 1, wherein said control, operating and display unit is configured so that said at least one parameter that currently limits the ground-speed control via said forward-travel regulator is displayed as a term in said control, operating, and display unit.

4. A self-propelled agricultural working machine as defined in claim 1, wherein said control, operating and display unit is configured so that said at least one parameter that currently limits the ground-speed control via said forward-travel regulator is displayed in a separate screen of said control, operating, and display unit.

5. A self-propelled agricultural working machine as defined in claim 4, wherein said separate screen covers further screens of said control, operating, and display unit at least part of a time and in at least certain areas.

6. A self-propelled agricultural working machine as defined in claim 1, wherein said control, operating and display unit is configured so that at least one control limit selected from the group consisting of a lower control limit, an upper control limit, and a lower and upper control limit is definable for said at least one parameter.

7. A self-propelled agricultural working machine as defined in claim 6, wherein said control, operating, and display unit is configured so that said at least one control limit is effected in a manner selected from a group consisting of being entered, being changed, and both.

8. A self-propelled agricultural working machine as defined in claim 1, wherein said control, operating, and display unit is configured so that said at least parameter that currently limits the ground-speed control via said forward-travel regulator, and control limits defined for said particular parameter is displayed to the operator of the working machine in said control, operating, and display unit.

9. A self-propelled agricultural working machine as defined in claim 1, wherein said control, operating, and display unit is configured so that said working parameter of said working machine that limits said ground-speed control via said forward-travel regulator is a ground speed.

10. A self-propelled agricultural working machine as defined in claim 1, wherein said control, operating, and display unit is configured so that said working parameter of said working machine that limits said ground-speed control via said forward-travel regulator is a engine load drop.

11. A self-propelled agricultural working machine as defined in claim 1, wherein said control, operating, and display unit is configured so that said working parameter of said working machine that limits said ground-speed control via said forward-travel regulator is a state of an element selected from the group consisting of one or more working units, their working media, and both.

12. A self-propelled agricultural working machine as defined in claim 1, wherein said control, operating, and display unit is configured so that said working parameter of said working machine that limits said ground-speed control via said forward-travel regulator is a cleaning output of a crop-material cleaning device of the working machine.

13. A self-propelled agricultural working machine as defined in claim 1, wherein said control, operating, and display unit is configured so that said working parameter of said working machine that limits said ground-speed control via said forward-travel regulator is a separating output of a crop-material separating device of the working machine.

14. A self-propelled agricultural working machine as defined in claim 1, wherein said control, operating, and display unit is configured so that said working parameter of said working machine that limits said ground-speed control via said forward-travel regulator is a process of transferring a crop material to an external hauling vehicle.

15. A self-propelled agricultural working machine as defined in claim 1, wherein said control, operating, and display unit is configured so that said working parameter of said working machine that limits said ground-speed control via said forward-travel regulator is a distance from an end or a beginning of a row or a field detected by the working machine.

16. A self-propelled agricultural working machine as defined in claim 1, wherein said control, operating, and display unit is configured so that said working parameter of said working machine that limits said ground-speed control via said forward-travel regulator is a crop-material throughput delivered to the working unit of the working machine.

17. A self-propelled agricultural working machine as defined in claim 1, wherein said control, operating, and display unit is configured so that said working parameter of said working machine that limits said ground-speed control via said forward-travel regulator is a portion of crop grains located in a tailings device of the working machine.

18. A self-propelled agricultural working machine as defined in claim 1, wherein said control, operating, and display unit is configured so that said working parameter of said working machine that limits said ground-speed control via said forward-travel regulator is a volume of crop-material located in a tailings device of the working machine.

19. A self-propelled agricultural working machine as defined in claim 1, wherein said forward-travel regulator is configured so that a ground-speed control is always regulated automatically via said forward-travel regulator to a control limit based on the crop-material parameter or the working parameter of the working machine that has a limiting effect.

20. A self-propelled agricultural working machine as defined in claim 1, wherein the working machine is a combine harvester.
