Driver assistance system for agricultural working machine

1. A driver assistance system for an agricultural working machine, comprising

at least one control/regulating unit including a memory and which adjusts and monitors working parameters, quality parameters or both of the agricultural working machine in an automatable manner using a family of characteristics stored in the memory, and enables that a selectable process implementation strategy is specified in order to automatically monitor and/or adjust at least one working parameter, quality parameter or both of the agricultural working machine,

wherein the driver assistance system ( 28 ) suggests that the process implementation strategy ( 61 ) be changed at least when the specified setpoint value of one or more of the quality parameters ( 40 ) cannot be reached within the preselected process implementation strategy ( 61 ).

2. The driver assistance system according to claim 1 , wherein the driver assistance system ( 28 ) also suggests that the process implementation strategy ( 61 ) be changed when values can be obtained for one or more of the quality parameters ( 40 ) that are more favorable than the values defined by the specified setpoint value.

3. The driver assistance system according to claim 1 , wherein repeated interaction of the operator ( 24 ) with the driver assistance system ( 28 ) for the purpose of optimizing the working parameter ( 37 ) or the quality parameter ( 40 ) or both prompts the driver assistance system ( 28 ) to suggest that the process implementation strategy ( 61 ) he changed.

4. The driver assistance system according to claim 1 , wherein the communication with the driver assistance system ( 28 ) is in the form of natural language.

5. The driver assistance system according to claim 1 , wherein repeated interaction of the operator ( 24 ) with the driver assistance system ( 28 ) results in a shift of the weighting of at least one or more quality parameters ( 40 ).

6. The driver assistance system according to claim 1 , wherein the selectable process implementation strategies ( 61 ) include any of the group process implementation strategies consisting of a “maximum throughput” ( 61 b ), a “minimal fuel consumption” ( 61 c ), a “high threshing quality” ( 61 d ) and a “balanced” ( 61 a ).

7. The driver assistance system according to claim 1 , wherein effects on a mode of operation of the agricultural working machine ( 1 ) resulting from the process implementation strategy ( 61 ) being changed are incorporated in the display ( 60 ) of the driver assistance system ( 28 ) in the form of natural language.

8. The driver assistance system according to claim 1 , wherein a description of the suggested process implementation strategy ( 61 ) is depicted on the display ( 60 ) of the driver assistance system ( 28 ) in the form of natural language.

9. An agricultural working machine according to claim 1 , wherein the working parameters ( 37 ) can include machine parameter settings ( 38 b ) and crop parameters.

10. The agricultural working machine according to claim 9 , wherein the quality parameters ( 40 ) include parameters from the group consisting of “loss due to separation” ( 42 ), “loss due to cleaning” ( 43 ), “tailings” ( 41 ), “volume of tailings” ( 41 a ) and “portion of grain in the tailings” ( 41 b ).

11. The agricultural working machine according to claim 9 , wherein the families of characteristics ( 48 ) describing the quality criteria ( 40 ) are stored in automatic settings, wherein each automatic setting ( 48 ) is visualized in the display unit ( 22 ) by a pictogram ( 59 , wherein the activation of an automatic setting ( 45 ) is visualized by emphasizing the particular pictogram ( 59 ) and wherein the deactivation of the particular automatic setting ( 45 ) is visualized by hiding the particular pictogram ( 59 ).

12. The agricultural working machine according to claim 1 , wherein the control/regulating unit ( 23 ) is automatically activated upon start-up of the working machine ( 1 ).
