DRIVER ASSISTANCE SYSTEM FOR CONTROLLING AN AGRICULTURAL TEAM

Description

[0001] The present invention relates to a driver assistance system for controlling an agricultural vehicle combination according to the preamble of claim 1. Furthermore, an agricultural vehicle combination according to claim 14 and a method for operating the agricultural vehicle combination according to the preamble of claim 15 are the subject of the present invention.

[0002] A driver assistance system for controlling an agricultural vehicle combination, consisting of an agricultural machine and an attached implement, with the features of the preamble of claim 1, is known from DE 10 2018 123 478 A1. This document describes a driver assistance system with a detection device for recording operating parameters and a control device for regulating work processes of the machine and the implement. Operating parameters recorded by the detection device during the execution of a work order are transmitted to the control device, which performs predictive control of at least one work process of the agricultural machine, i.e., the adjustment of machine settings of the machine and the implement, based on information generated by an online learning algorithm based on the recorded operating parameters.The system assigns geodata generated by a tracking system to the recorded operating parameters to create georeferenced parameter data. This georeferenced parameter data is then applied online by the online learning algorithm to generate the information for predictive control. The driver assistance system is designed to adjust the operating parameters during the execution of a work order in a field to optimize the operation of the tractor-implement combination. This does not affect the initial setting of the tractor-implement combination's operating parameters at the start of the work order. This setting is the responsibility of the operator. Particularly in agricultural contracting, the operator working on a specific field or area changes frequently during a harvest season or the following year.Consequently, the machine settings at the start of a work order vary depending on the operator. Adjusting machine parameters within the field according to field conditions, as described in DE 10 2018 123 478 A1, is time-consuming, as at least one pass must be driven to gather the information required for predictive control, and it also places high demands on the computing power of the driver assistance system. Furthermore, the individual operator profiles set by each operator before and during the execution of the work order in the field or area generally vary.

[0003] Based on the aforementioned prior art, the invention aims to further develop a driver assistance system of the type mentioned at the outset, which avoids the disadvantages of the prior art.

[0004] This problem is solved according to the invention by a driver assistance system with the features of claim 1. Advantageous further developments are the subject of the dependent claims.

[0005] According to claim 1, a driver assistance system for controlling an agricultural vehicle combination is proposed, wherein the vehicle combination comprises a tractor and an agricultural implement, wherein the driver assistance system is connected by a communication means to at least one database in which machine settings of at least one combination of tractor and implement are stored.According to the invention, it is proposed that the driver assistance system is designed and configured to detect the first entry of the tractor-implement combination into a field or area for cultivation by crossing a geolocated boundary of the field or area, to load a data record of a driver profile and / or an associated machine setting of the tractor-implement combination from the at least one database when the field or area is first entered, and to adjust the tractor and / or the implement according to the loaded driver profile and / or the loaded machine setting.

[0006] The key consideration is that when the tractor-implement combination first enters the field or area for cultivation, the detection of the field's geolocated boundary triggers the automatic loading of a data record containing a driver profile and / or machine settings specific to that field or area. The tractor-implement combination then uses this field- or area-specific data record to carry out the cultivation. This reduces the setup time for the tractor-implement combination's machine settings. Furthermore, it relieves the operator of the burden of manually specifying machine settings. Field- or area-specific loading of the driver profile is particularly advantageous when different operators use the tractor to perform agricultural work processes.

[0007] In this context, the initial entry of a field or area by the agricultural vehicle combination means that the field or area is being entered for the first time by the agricultural vehicle combination upon arrival at the field or area in order to carry out a currently scheduled work order. The respective field or area is mapped. The cartographic data is available to the driver assistance system or can be made available to it. The first time the vehicle combination, in its existing combination of tractor and implement, passes an access point of the field or area in order to carry out a currently scheduled work order is recognized as the initial entry.This also includes the traversing of the same field or area by a team whose composition has changed during a workday in order to carry out a new, different, or the same work order on the field or area. The midday change of the work order and / or the change in the composition of the team, followed by the subsequent re-traversing of the same field or area, constitutes the initial traversal of the field or area.

[0008] In particular, the driver assistance system can be designed and configured to detect when the vehicle leaves the field or area by crossing the geolocated boundary and, depending on this, to initiate at least one action to be triggered by the driver assistance system. For example, an automated billing of the work carried out by the vehicle combination in the field or area can be initiated as an action.

[0009] The action to be triggered can include saving changes to the machine settings of the tractor and / or implement and / or the driver profile in the database during the processing of the field or area.

[0010] Preferably, the driver assistance system can automatically derive the combination of the vehicle and implement from a work order transmitted by a remote data processing system and / or determine or supplement it through manual order entry via a user interface of the driver assistance system. The work order can contain information about the activity to be carried out in the field or area, the operator, the field or area itself (such as its name or field number), the crop type, the combination of tractor, implement, and tractor tires, route planning, soil and working conditions, and / or application data.

[0011] According to further training, the driver assistance system can be designed and configured to communicate bidirectionally with the tractor's and implement's control units independently of each other via at least one bus system. This allows machine settings of the tractor and implement to be exchanged independently between them and the driver assistance system.

[0012] Preferably, the driver assistance system can be designed and configured by an operator to manually select machine settings and / or driver profiles for the vehicle combination after exceeding the geolocated boundary of the field or area.

[0013] In particular, the driver assistance system can be configured and designed to automatically generate, especially interactive, recommendations for machine settings after the geolocated boundary of the field or area has been crossed. This allows for consideration of situations where no common field-specific data set is available for the tractor and implement combination used to cultivate the field or area. For example, specific machine settings for the tractor and implement can be loaded from the database, settings that were previously stored for the field or area at a time when the tractor or implement was working the field or area. The same applies to the driver profile to be loaded.

[0014] According to further training, the driver assistance system can be designed and configured to georeferencedly record soil data, harvest data, machine data, implement data, tire data, and / or changes in the driver profile during field or area cultivation. This allows for the expansion of an existing database. Furthermore, georeferenced recording enables the documentation of the cultivation process for traceability and facilitates subsequent analysis to improve efficiency for future deployments of the vehicle combination.

[0015] The driver assistance system can be configured to transmit recorded soil data, harvest data, machine data, implement data, tire data, and / or changes to the driver profile to the remote data processing system for evaluation and / or storage. This allows for continuous updating of the data records. Furthermore, it offers the possibility of field-specific documentation of work order completion, for example, for later analysis of workflows or invoicing.

[0016] In particular, the driver assistance system may be designed and configured to, upon initial detection of a tractor-implement combination entering a field or area for cultivation, whose combination does not have corresponding, in particular field-specific, machine settings stored in the at least one database, by means of initial machine settings stored in the at least one database and / or in the control units of the tractor and the implement, which are specific to historical harvest data and / or soil data of the field or area to be cultivated stored in the at least one database.

[0017] According to a preferred embodiment, the driver assistance system can receive position data from at least one position sensor assigned to the vehicle combination, wherein the at least one position sensor can be located on the tractor and / or on the implement and / or be a position sensor carried by an operator of the vehicle combination.

[0018] Preferably, the loading of the driver profile and / or the associated machine setting assigned to the field or area can be carried out from at least one database upon the first entry into the field or area by time-dependent comparison of the retrieval time with the time of storage of the driver profile and / or the associated machine setting of the vehicle combination assigned to the detected field or area. In this way, a machine setting and / or a driver profile can be loaded which, in addition to the spatial dependency, also exhibit a temporal dependency, in particular a seasonal one.

[0019] In particular, at least one database can be stored in a remote data source, where the remote data source is remote data processing hardware, especially a cloud-based data processing system. However, the remote data source can also be a data server located remote from the system, which communicates with the system via an internet connection or similar means.

[0020] According to a further teaching as defined in claim 14, which has independent significance, a vehicle combination comprising a tractor and an agricultural implement, wherein the vehicle combination is equipped with a driver assistance system, is claimed. The essential feature of this further teaching is the vehicle combination being equipped with a driver assistance system as defined in the first-mentioned teaching. Reference may be made to all details relating to the first-mentioned teaching that are suitable for explaining the agricultural vehicle combination as a whole.

[0021] According to a further teaching as claimed in claim 15, which has independent significance, a method for operating a vehicle combination comprising a tractor and an agricultural implement is claimed, wherein the vehicle combination is controlled by a driver assistance system assigned to it, in particular a proposed driver assistance system, wherein the driver assistance system is connected by a communication means to at least one database in which machine settings of at least one combination of tractor and implement are stored, wherein the driver assistance system detects the initial entry of the vehicle combination into a field or area for cultivation by crossing a geolocated boundary of the field or area.a driver profile and / or an associated machine setting assigned to the field or area is loaded from at least one database upon first entering the field or area, and the tractor and / or the implement is set according to the loaded driver profile and / or the loaded machine setting.

[0022] The present invention is explained in more detail below with reference to an embodiment illustrated in the drawings.

[0023] They show: Fig. 1 shows a schematic and exemplary agricultural team; and Fig. 2 shows an exemplary simplified flowchart.

[0024] Fig. 1Figure 1 schematically and exemplarily shows an agricultural vehicle combination 4, comprising a tractor 1 with a field sprayer as an implement 2. The tractor 1 can be equipped with at least one implement 2 via at least one implement interface. The implement 2 can be any implement that can be connected to the tractor 1 via the implement interface as described above. For example, the agricultural implement 2 could be the field sprayer shown in the drawing, a plow, a baler, a seed drill, or the like. The tractor 1 and / or the implement 2 have at least one position sensor 3 for receiving position data provided by a positioning system 21.

[0025] The agricultural vehicle combination 4 is equipped with a driver assistance system 5, which is designed and configured to control the agricultural vehicle combination 4. The driver assistance system 5 has a user interface 6 for inputting and outputting information, a processing unit 7, a storage unit 8, and a sensor array 9. In addition to the position sensor 3, the sensor array 9 is equipped with at least one sensor 10, 11, and preferably with several sensors 10, 11, for recording measured values. The sensors 10 are assigned to the working machine 2, and the sensors 11 are assigned to the implement 3.

[0026] The driver assistance system 5 is connected to at least one database 13 via a communication means 12. The communication means 12 can be a network implemented locally in the vehicle combination 4, a mobile network, or a WLAN. The at least one database 13 can be stored in the memory unit 8 of the driver assistance system 5.

[0027] Alternatively or additionally, at least one database 13 can be stored in a data source remote from the system. In this case, at least one database 13 can be stored in a storage unit 15 as a data source for a data processing system 14. The data processing system 14 comprises a computing unit 16 and a user interface 17.

[0028] The data processing system 14 can be implemented as a farm management system located on suitable data processing hardware at a farmstead 18. Alternatively, the remote data processing system 14 can be a cloud-based data processing system located in a remote data center.

[0029] In at least one database 13, data records 39 with machine settings 20 of at least one combination of tractor 1 and implement 2 are stored. Furthermore, at least one driver profile 19 of an operator of the vehicle combination 4 is stored in at least one database 13 as data record 39.

[0030] The driver assistance system 5 uses a driver profile 19 for its operation and a machine setting 20 of the vehicle combination 4 for controlling the vehicle combination 4, both of which are loaded from at least one database 13. Data included in the driver profile 19 and the machine setting 20 of the vehicle combination 4 are described below with reference to Fig. 2 explained.

[0031] The tractor 1 and the implement 2 can exchange information with each other via a bus system 24. The driver assistance system 5 is designed and configured to communicate bidirectionally with at least one control unit 22 of the tractor 1 and at least one control unit 23 of the implement 2 independently of each other via at least one bus system, preferably bus system 24.

[0032] What's next? Fig. 1As can be seen, the tractor team 4 moves along a route 29 to a field 25 to cultivate it. After cultivating field 25, the tractor team 5 can travel along another route 30 to another field 26 or another area 40 to cultivate it as well. The routes 29 and 30 can be public roads and paths and / or field tracks or similar connecting fields 25 and 26.

[0033] The respective fields 25, 26, and areas 40 are mapped. The cartographic data is available to the driver assistance system 5 or can be made available to it. Fields 25, 26, and areas 40 are closed and have geolocated boundaries 27 as administrative limits. The geolocated boundaries 27 of fields 25 and 26 are simplified here as rectangles, but they can have different shapes. The geolocated boundaries 27 make it possible to distinguish between the location of the vehicle combination 4 inside and outside the geolocated boundaries 27 or fields 25 and 26, respectively.

[0034] The driver assistance system 5 is designed and configured to detect the initial entry of the vehicle combination 4 into one of the fields 25 or 26 for processing by crossing the geolocated boundary 27 of the field 25 or 26. Crossing the geolocated boundary 27 to enter field 25 or field 26 for the first time is detected by passing an access point 28. For this purpose, the vehicle combination 4 can transmit its position at regular intervals or allow its position to be queried externally. This location determination can be carried out, for example, by the mobile communication system at the cell level or, based on coordinates, by the satellite navigation system 21.

[0035] In this context, the first entry of field 25, 26 by the team 4 means that field 25, 26 is entered for the first time by the agricultural team 4 upon reaching field 25, 26 or area 40 in order to carry out a currently being executed work order 32; the first passing of access point 28 by the team 4 in an existing combination is detected. This also includes the entry of a team whose composition has changed during a workday into the same field 25, 26 or the same area 40 in order to execute a new, different, or the same work order 32 on field 25, 26. The intraday change of the work order 32 and / or the change in the composition of the team 4 and the associated repeated passing of access point 28 also constitute an initial entry into field 25, 26.

[0036] The detection of the first entry into field 25, for example, causes the driver assistance system 5 to load a data record 39 of a driver profile 19 and / or a machine setting 20 of the vehicle combination 4 assigned to field 25 from the at least one database 13 when the field 25 is entered for the first time, and to set the tractor 1 and / or the implement 2 according to the loaded driver profile 19 and / or the loaded machine setting 20.

[0037] In Fig. 2 An exemplary simplified flowchart is shown, which explains the procedure for operating the vehicle combination 4 when the first entry into field 25 and / or field 26 is detected.

[0038] Work order 32 for the tractor unit 4 to work field 25 and / or field 26 can be received by the data processing system 14, which is implemented as a farm management system. If necessary, the operator of the tractor unit can manually process the received work order 32 using the driver assistance system 5. This can preferably be done via an interactive dialogue controlled by the driver assistance system 5.

[0039] Work order 32 can contain basic information about the task to be performed, the operator, the client, fields 25 and 26, and / or the crop type. Furthermore, work order 32 can contain information about the tractor unit 4, i.e., its composition of tractor 1 and implement 2, route planning, soil conditions, environmental conditions, and / or application data. Work order 32, generally generated by data processing system 14, can be supplemented by the operator of tractor unit 4 using the driver assistance system 5. An existing work order 32 can be continuously updated by data processing system 14 to take into account any changes, such as changes to route planning or environmental conditions, during the execution of work order 32.

[0040] In process step 33, the arrival at access point 28 for the initial processing of field 25 within the scope of the specified work order 32 is detected. The necessary localization data is received by position sensor 3.

[0041] In process step 33, the composition of the vehicle combination 4 can be automatically derived from the work order 32 transmitted by the remote data processing system 14 and / or determined or supplemented by manual order entry via a user interface of the driver assistance system 5.

[0042] Additionally or alternatively, in process step 33, information can be received from the control units 22, 23 of the tractor 1 and the implement 2, which the driver assistance system 5 can evaluate to determine the combination of the tractor 1 and implement 2.

[0043] Database 13 contains field-specific data records 39 of one or more driver profiles 19. At least one driver profile 19 contains information on the name and telephone number of an operator, on terminal settings of tractor 1 and / or implement 2, such as units, language setting and the like, on comfort settings, for example radio configuration, or settings of heating, ventilation and air conditioning in the driver's cab of tractor 1, on the type of user identification, for example by means of profile, iBeacon, task or the like.

[0044] Furthermore, the database contains 13 data records (39) of machine data (34) for one or more tractors (1). The machine data (34) contains information on vehicle weight, vehicle dimensions, restrictions, drivetrain, attachment interfaces, and the like.

[0045] Database 13 contains 39 records of attachment data 35 for one or more attachments 2. The attachment data 35 includes information on the category, type or species of the attachment, geometries, weight, configuration and / or equipment, power distribution and the like.

[0046] Furthermore, the database contains 13 records (39) relating to tire data, 36 of which pertain to one or more tires from tractors. The tire data includes information on dimensions, load-bearing capacity at various pressures, and similar specifications.

[0047] Furthermore, the database contains 13 data records (39) relating to soil data (37) for one or more fields (25, 26) or areas (40). The soil data (37) includes information on the traction ratio, rolling resistance, soil matrix potential, and soil pre-compaction.

[0048] The database also contains 13 records 39 relating to harvest data 38 for one or more fields 25, 26 or areas 40. The harvest data 38 can contain processing-specific information on settings of tractor 1 and / or implement 2, for example engine pressure, cutting height, baling pressure of balers as implements and the like.

[0049] All of the aforementioned data records 39 have in common that they are georeferenced and stored in database 13. The data records 39 are assigned to individual fields 25 and 26. The stored data records 39 for a field 25 or 26 vary, in particular, depending on the operator, tractor 1, and / or implement 2, as well as the associated machine data 34, implement data 35, tire data 36, ​​soil data 37, and / or harvest data 38.

[0050] The driver assistance system 5 determines, upon first entering field 25, the data record 39 or data records 39 of the driver profile 19 assigned to field 25 and / or the machine setting 20 assigned to field 25 of the vehicle combination 4 from the machine data 34, implement data 35, tire data 36, ​​soil data 37 and / or harvest data 38, which corresponds to the combination of the vehicle combination 4 determined in process step 33 and the information obtained from the work order 32 to be carried out on field 25.

[0051] The driver assistance system 5 sets the tractor 1 and / or the implement 2 in a field-specific manner according to the driver profile 19 loaded as data set 39 and / or the machine setting 20 loaded as data set 39, before the cultivation of the field 25, 26 is started by the combination 4.

[0052] The data set 39 with machine settings 20 includes the automatic control of control units 22, 23 and / or actuators of tractor 1 and implement 2 by the driver assistance system 5 to optimally adjust them, as well as instructions for manual settings to be carried out by the operator on the tractor and the implement 2.

[0053] An automatic control of control unit 22 and actuators of the tractor 1 includes the bus system 24, which is preferably an ISO bus system, the control, the drive motor, the drive train, the PTO speed, the hydraulics, the engine pressure, the all-wheel drive, the differential lock, the trailer hitch, the tire pressure by means of a tire pressure control system.

[0054] An automatic control of control unit 23 and actuators of the implement 2 includes the bus system 24, which is preferably an ISO bus system, the section control, the press pressure, the height adjustment of crop intake devices.

[0055] The possible options for automatic control vary depending on the equipment, type and model of tractor 1 or implement 2.

[0056] Manual adjustments to tractor 1 may include ballasting, adjusting the hitch, or similar tasks.

[0057] Manually adjustable settings on the attachment 2 may include the working depth or cutting height, the adjustment of share wings, or similar.

[0058] The possible options for manually making settings also vary depending on the equipment, type and model of tractor 1 or implement 2.

[0059] The driver assistance system 5 is designed and configured to georeference soil data 37, harvest data 38, machine data 34, which are acquired by means of sensors 10, 11, and / or changes in the driver profile 19 during the processing of field 25, 26 or area 40.

[0060] The driver assistance system 5 transmits the recorded ground data 37, harvest data 38, machine data 34 and / or changes to the driver profile 19 to the remote data processing system 14 for evaluation and georeferenced storage.

[0061] Furthermore, the driver assistance system 5 is designed and configured to detect when the vehicle leaves field 25, 26 by crossing the geolocated boundary 27 and, depending on this, to initiate at least one action to be triggered by the driver assistance system 5. Leaving field 25, 26 is detected when the vehicle combination 4 passes an exit point 31. The entry point 28 and the exit point 31 can be spatially separated or coincide at a single point, as illustrated by the example of a surface 40 to be processed.

[0062] The at least one action to be triggered may include saving changes to the machine settings 20 of tractor 1 and / or implement 2 and / or driver profile 19 made during the processing of field 25, 26 or area 40 in the database 13.

[0063] The driver assistance system 5 may have a user interface for the manual selection by an operator of suggested machine settings 20 and / or driver profiles 19 after crossing the geolocated boundary 27 of field 25, 26 or area 40.

[0064] Here, and preferably, the driver assistance system 5 can be designed and configured to automatically, and in particular interactively, generate recommendations for machine settings after the geolocated boundary 27 of field 25, 26 or area 40 has been crossed. The automatic generation of recommendations by the driver assistance system 5 is relevant in situations where no common field-specific data set 39 for a driver profile 19 and / or a machine setting 20 is available for the tractor 1 and the implement 2 in their combination as a unit 4, with which field 25, 26 or area 40 is to be cultivated. This can be the case, for example, when a new tractor 1 and / or implement 2 is purchased. The same applies to a new combination of existing machines that have not previously been used in this new combination on field 25, 26.

[0065] For example, specific machine settings 20 can be loaded from database 13 for tractor 1 and implement 2, which were stored for field 25, 26 or area 40 at a previous point in time when tractor 1 or implement 2 was working in that field. The same applies analogously to driver profile 19.

[0066] The driver assistance system 5 can be designed and configured to, upon initial detection of the entry of a tractor-implement combination 4 into field 25, 26 or area 40 for cultivation, whose combination of tractor 1 and implement 2 does not have a corresponding, in particular field-specific, storage of machine settings 20 in the at least one database 13, by means of initial machine settings stored in the at least one database 13 and / or in the control units 22, 23 of the tractor 1 and the implement 2, which are specific for historical soil data 37 and / or harvest data 38 of the field 25, 26 or area 40 to be cultivated stored in the at least one database 13.

[0067] Another aspect is the temporal comparison between the detection of the initial entry into field 25, 26 and the time of storage, also by means of an update, of one or more field-specific data records 39 that are assigned to the relevant vehicle combination 4. The loading of the driver profile 19 and / or the associated machine setting 20 assigned to field 25, 26 or area 40 upon the initial entry into field 25, 26 or area 40 from at least one database 13 can be carried out by a time-dependent comparison of the retrieval time, which corresponds to the time of the initial entry by the vehicle combination 4 to be configured, with the time of the earlier storage of the driver profile 19 and / or the associated machine setting 20 of the vehicle combination 4 assigned to the detected field 25, 26 or area 40.
