fig1 shows an agricultural working machine 1 designed as a combine harvester 2 as it harvests a crop 4 which is growing on a territory 3 to be worked . in a manner known per se , combine harvester 2 includes a crop material storage unit 6 which is designed as a grain tank 5 and stores the harvested corn , and an unloading device 7 , via which grain tank 5 can be emptied . a crop edge detection device 8 is assigned to the front of combine harvester 2 , which detects crop edge 9 of crop 4 to be harvested . in a manner known per se , crop edge detection device 8 can be designed as a laser sensor , the oscillating detection beam 10 of which generates a depiction of the position of crop edge 9 in an evaluation unit 11 assigned to combine harvester 2 and , with consideration for working width 13 of combine harvester 2 determined by the width of front attachment 12 , generates driving routes 14 for the inventive route planning system 15 , which will be described in greater detail . to empty grain tank 5 , combine harvester 2 also interacts with an unloading vehicle 16 in that combine harvester 2 approaches unloading vehicle 16 to be unloaded , or unloading vehicle 16 approaches combine harvester 2 . it is also feasible that combine harvester 2 and unloading vehicle 16 include a gps antenna 17 , which transmits gps signals 19 generated by satellite systems 18 in a manner known per se to an evaluation unit 11 . driving routes 14 of inventive route planning system 15 are generated , also depending on the working width 13 of combine harvester 2 . it is within the scope of the present invention that crop edge detection device 8 and gps - based system 17 - 19 can also be located on any type of agricultural working machine 1 . for simplicity , the present invention will be described below essentially with reference to the complex combine harvester 2 system , although the present invention is not limited thereto . in an inventive manner , crop material quantity 20 stored in particular crop material storage unit 6 will be reconciled in a manner to be described in greater detail depending on characteristic parameters , and the reconciliation is adjusted dynamically — in a manner to be described in greater detail — to changes in the characteristic parameter ( s ). the characteristic parameters of the reconciliation can be crop material - specific parameters 21 , field - specific parameters 22 and / or machine - specific parameters 23 . according to fig2 , combine harvester 2 includes a crop material storage unit 6 , which is designed as a grain tank 5 , to which a grain flow 25 is delivered via an elevator unit 24 . this grain flow 25 results — in a manner which is known per se and is therefore not described in greater detail — from a crop material flow 26 ; to this end , crop material flow 26 typically passes through threshing parts 27 , separating units 28 , and cleaning units 29 . crop material flow 26 is generated by harvesting and combining a grown crop 4 in a header . combine harvester 2 shown in fig2 also includes previously - described crop edge detection device 8 and gps system 17 which generate crop edge signals and driving route signals 32 in a manner known per se . for simplicity , the two systems 8 , 17 are shown on the same combine harvester 2 . typically , combine harvester 2 can be equipped with only one of these systems 8 , 17 . crop edge and driving route signals 32 which are generated are transmitted to evaluation unit 11 , which is typically located in driver &# 39 ; s cab 33 . in addition , grain tank 5 includes a fill level detection device 34 which is known per se ; it generates a grain tank fill level signal 35 and transmits it to evaluation unit 11 . it is within the scope of the present invention that fill level detection device 34 is also designed as a sensor device which measures grain throughput ; the throughput sensors are integrated in grain elevator 24 and in unloading device 7 . in this case , the fill level of grain tank 7 would result from the difference between incoming grain flow 25 and grain flow 36 which is removed from grain tank 5 via unloading device 7 . in the exemplary embodiment shown , fill level detection device 34 is therefore composed of inventive sensors 37 for determining crop material quantity 20 stored in grain tank 5 . grain tank fill level signals 25 , 35 , 36 generated by fill level detection unit 34 are also machine - specific parameters 23 , according to the present invention . a throughput and moisture measurement device 39 — which is known per se and will therefore not be described in greater detail — is assigned to feed rake 38 and detects the throughput and moisture content of crop material flow 26 entering feed rake 38 which accommodates header 31 of combine harvester 2 . throughput and moisture signals 40 generated by throughput and moisture measurement device 39 are also transmitted to evaluation unit 11 and simultaneously represent crop material - specific parameters 21 , according to the present invention . it would also be feasible , however , for crop material - specific parameter 21 to be the crop material type ; this information can then be entered directly in evaluation unit 11 by the operator of combine harvester 2 , or evaluation unit 11 can obtain this information automatically from external data sources . it is also within the framework of the present invention for evaluation unit 11 to include crop - specific parameters 22 , such as the geometry of territory 3 to be worked , driving routes 14 generated by combine harvester 2 or a route planning system 15 , slopes on ground 41 to be traversed , and the location of obstacles . with regard for crop - specific parameters 22 , it is also possible for parameters 22 described to be entered by the operator of combine harvester 2 or to be obtained from external sources . it is also within the scope of the present invention that evaluation unit 11 takes into account only a few or a combination of certain available parameters 21 - 23 . evaluation unit 11 is designed , at the least , such that it takes not only grain tank fill level signals 25 , 35 , 36 into account , but also at least one further characteristic parameter 21 - 23 and , based on its correlation with grain tank fill level signals 25 , 35 , 36 , generates at least one bit of information 42 which reconciles a crop material quantity 20 stored in grain tank 5 . in the simplest case , the bit of reconciling information 42 can be a forecast of expected crop material yields or the determination of an unloading position of combine harvester 2 — which will be described in greater detail below — at which crop material quantity 20 is removed from grain tank 5 using unloading device 7 . evaluation unit 11 also includes a display unit 43 in order to better visualize the generated bit of information 42 with which crop material quantity 20 is reconciled . fig3 shows inventive route planning system 15 in detail . for simplicity , the present invention is described essentially with reference to display unit 43 , which is shown greatly enlarged . in display unit 43 , combine harvester 2 is performing a harvesting operation in crop 4 . combine harvester 2 can be oriented at crop edge 9 using crop edge detection device 8 or in a gps - based manner using gps antenna 17 . a first driving track 44 is generated in evaluation unit 11 depending on driving route signals 32 . first driving track 44 is depicted using dashed lines in display unit 43 in the exemplary embodiment shown . this driving track 44 also has the property that it represents the harvesting path already covered by combine harvester 2 . in the manner described previously , suitable systems generate at least one grain tank fill level signal 35 , based on which a bit of information 42 with which crop material quantity 20 is reconciled is generated in evaluation unit 43 . in the case shown , information 42 includes the position of an unloading point 45 in territory 3 to be worked . in display unit 43 , the driving path to this unloading point 45 is visualized using a solid driving track 46 . driving route 14 to be worked after unloading point 45 has been reached can be depicted using dashed lines , for instance , so that the property of this further driving track 47 is also visualized using a special graphical shape . since the unloading process typically proceeds such that unloading vehicle 16 is driven toward combine harvester 2 or combine harvester 2 is driven toward unloading vehicle 16 to unload grain tank 5 , it must be ensured that unloading vehicle 16 can accompany driven combine harvester 2 , or that unloading vehicle 16 is positioned such that combine harvester 2 can reach unloading vehicle 16 and transfer its load to it . this is ensured in a manner according to the present invention by the fact that at least one crop - specific parameter 22 is taken into account during generation of information 42 with which crop material quantity 20 is reconciled . in this case , this can be , e . g ., remaining distance 48 required for grain tank 5 to be completely emptied when combine harvester 2 is driven , without the unloading vehicle colliding with obstacles or without the end of crop 4 or territory 3 being reached . in this manner , a continual unloading process is attained , which reduces or nearly completely prevents unproductive standstill times from occurring during the process of unloading combine harvester 2 . it is within the scope of the present invention that the position of unloading point 45 and , therefore , the contents of generated information 42 are dynamically adaptable to changing grain tank fill level signals 35 and crop material - specific , crop - specific and machine - specific parameters 21 - 23 . that is , the position of unloading point 45 can be displaced dynamically in arrow direction 49 ; the position of generated driving tracks 46 , 47 can therefore also be changed dynamically . in an embodiment of the present invention , an unloading point in time 51 can be determined in addition to or instead of the determination of unloading point 45 , and it can be visualized in display unit 43 . in the simplest case , unloading point in time 51 is determined in evaluation unit 11 based on the ground speed of combine harvester 2 and the increase in crop material quantity 20 in grain tank 5 . due to the gradual increase in crop material quantity 20 in grain tank 5 , unloading point in time 51 displayed progresses toward zero . it is also within the scope of the present invention that remaining distance 48 which combine harvester 2 probably needs to cover to reach the unloading point is displayed numerically in a display window 52 . in the simplest case , evaluation unit 11 determines the length of remaining distance 48 based on the ground speed of combine harvester 2 , crop material quantity 20 stored in grain tank 5 , and the conveying speed of unloading device 7 . this value is also adapted dynamically to the current fill level of grain tank 5 . it is also within the scope of the present invention that remaining distance 48 , unloading point in time 51 and unloading point 45 can be displayed individually or in combination in display unit 43 . since the determination of unloading point 45 and unloading point in time 51 and remaining distance 48 are based on the fill level of grain tank 5 , evaluation unit 11 first forecasts the fill level “ grain tank full ” based on the grain yield which was determined ; it is determined in a manner known per se based on the ground speed of combine harvester 2 , its working width 13 , and grain flow 25 which is determined per unit time and is conveyed into grain tank 5 . depending on further grain flow 25 conveyed into grain tank 5 and grain flow 36 which is optionally removed therefrom , evaluation unit 1 updates the values for unloading point 45 , unloading point in time 51 and remaining distance 48 . since an optimal unloading process is characterized , in particular , by the fact that crop 4 is harvested continually and the vehicle systems used in the harvesting process are moved as little as possible over the territory to be worked , in order to protect the ground , inventive route planning system 15 can also be designed such that evaluation unit 11 defines an unloading strategy — with consideration , at the least , for the fill level of grain tank 5 , unloading point 45 which was determined , the position of at least one unloading vehicle 16 , and a driving route 14 which has been determined — which adjusts at least one of these parameters depending on the remaining parameters . this has the particular advantage that route planning system 15 takes all essential influential factors of a “ harvesting process chain ” into account . inventive reconcilation process can also be designed such that information 42 which has been generated includes crop material quantity 20 to be expected in crop 4 which has been worked , and the capacity of unloading vehicles 16 required therefore . in the exemplary embodiment shown , this could be designed such that several combine harvesters 2 are used in the same territory 3 , and the reconciliation of the unloading capacity takes into account the waiting period experienced by unloading vehicle 16 when a combine harvester 2 is ready to be unloaded . in this manner , it is ensured for a large number of combine harvesters 2 used in the same territory 3 that the unloading capacity is distributed such that a standstill of combine harvesters 2 is prevented , as are unloading positions which are difficult or impossible to reach . this “ waiting time reconciliation ” can also take an optimization criterium into account . as described above , the optimization criterium can be “ short driving distances of unloading vehicle 16 on territory 3 to be worked ” and / or “ optimal filling of unloading vehicle 16 ” and / or “ prioritization of agricultural working machine 1 to be approached ”. according to fig3 , a large number of combine harvesters 2 and unloading vehicles 16 can be involved in the harvesting process . it is within the scope of the present invention that further agricultural working machines 1 can be integrated in the process chain . given that each combine harvester 2 and every unloading vehicle 16 includes an evaluation unit 11 with associated display unit 43 , and every evaluation unit 11 is in contact with a central unit 50 , which is located on one of the participating vehicles 1 , 2 , 16 or is stationary at a central location , the control of one or more unloading vehicles 16 can be carried out automatically depending on one or more generated unloading points 45 . this coordinated motion of unloading vehicles 16 and combine harvester 2 on a territory 3 to be worked can also be further optimized when each of the evaluation units 11 includes a display unit 43 , in which vehicles 1 , 2 , 16 — which are also incorporated in inventive route planning system 15 — are displayed . it lies within the abilities of one skilled in the art to modify route planning system 15 described above in a manner not shown or to use it in other machine systems to obtain the effects described , without leaving the scope of the present invention . it will be understood that each of the elements described above , or two or more together , may also find a useful application in other types of constructions differing from the type described above . while the invention has been illustrated and described as embodied in a route planning system for agricultural working machines , it is not intended to be limited to the details shown , since various modifications and structural changes may be made without departing in any way from the spirit of the present invention . without further analysis , the foregoing will so fully reveal the gist of the present invention that others can , be applying current knowledge , readily adapt it for various applications without omitting features that , from the standpoint of prior art , fairly constitute essential characteristics of the generic or specific aspects of this invention .
