Description

Technical Field

[0001] The 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 an agricultural vehicle combination according to the preamble of claim 15 are also subject matter of the invention. Background Art

[0002] DE 10 2018 123 478 A1 discloses a driver assistance system for controlling an agricultural vehicle set, the vehicle set comprising an agricultural working machine and attached equipment arranged thereon, having the features according to the preamble of claim 1. A driver assistance system is described herein, which has a detection device for detecting operating parameters and a control device for regulating the working process of the working machine and the attached equipment. The operating parameters detected by the detection device during the execution of the work task are transmitted to the control device, which performs predictive regulation of at least one working process of the agricultural working machine based on the information generated by the detected operating parameters according to an online learning algorithm (Online-Lern-Algorithmus), that is, adjusts the machine settings (Maschineneinstellung) of the working machine and the attached equipment. The geographical data generated by the positioning system are assigned to the acquired operating parameters to generate georeferenced parameter data, wherein the online learning algorithm uses the georeferenced parameter data online to generate information for predictive regulation. The driver assistance system according to the category is designed to adjust the settings of the operating parameters during the execution of the work task on the field in order to optimize the working mode of the vehicle group. In this case, this does not affect the settings (Einstellung) of the operating parameters of the vehicle group at the beginning of the work task. This setting is the responsibility of the operator operating the vehicle group. In particular, for contractors, it is necessary to adjust the settings of the operating parameters of a certain field (Feld) or a certain plot / site during the harvest season or in the following year. The operators who perform the work tasks change. As a result, the machine settings made at the beginning of the work tasks also change depending on the operator. As disclosed in DE10 2018 123 478 A1, adjusting machine parameters within the field according to field conditions is time-consuming, because at least one driving track must be traveled to obtain the information required for predictive adjustment, and high requirements are placed on the computing power of the driver assistance system. Similarly, the individualized driver profiles (Fahrerprofiles) set by each operator before and during the work tasks on the field or site usually also change. Summary of the invention

[0003] Based on the above-mentioned prior art, the object of the present invention is to further develop a driver assistance system of the type mentioned in the introduction in such a way that the disadvantages of the prior art are avoided.

[0004] This object is achieved according to the invention by a driver assistance system having the features of claim 1. Preferred developments are the subject matter of the dependent claims.

[0005] According to claim 1, a driver assistance system for controlling an agricultural vehicle group is proposed, wherein the vehicle group includes a tractor / tractor (Traktor) and an agricultural attachment, wherein the driver assistance system is connected to at least one database via a communication mechanism or a communication unit (Kommunikationsmittel), in which machine settings of at least one combination of the tractor and the attachment are stored. According to the invention, the driver assistance system is implemented and arranged to: based on the vehicle group crossing the The method comprises the steps of: detecting the first driving of the vehicle group on the field or field for processing by the geo-positioned boundaries of the field or field, loading (laden) a data set of the driver profile assigned to the field or field and / or a data set of the machine settings assigned to the vehicle group from the at least one database when driving on the field or field for the first time, and setting the tractor and / or the attached equipment according to the loaded driver profile and / or the loaded machine settings.

[0006] The key consideration is that the detection of the first driving of the vehicle group on a field or field for processing by detecting the geo-positioned boundaries of the field or field triggers the automatic loading of a data set of a driver profile assigned to the field or field and / or a data set of the assigned machine settings. The vehicle group performs the above processing with the help of the data set of the driver profile loaded specifically for the field or field and / or the machine settings loaded specifically for the field or field. This reduces the setting time of the machine settings of the vehicle group. In addition, the operator does not need to specify the machine settings of the vehicle group himself. The loading of the driver profile specific to the field or field is particularly advantageous when different operators use at least the tractor to perform agricultural work processes.

[0007] In this context, the first time a vehicle group drives on a field or a site means that when the agricultural vehicle group arrives at the field or the site, it drives on the field or the site for the first time in order to perform the work task currently to be performed. The corresponding field or the corresponding site has been detected in a cartographic manner. In this case, the cartographic data can be used by the driver assistance system or can be provided to the driver assistance system. The first time a vehicle group passes through the entry point of the field or the site for the first time with the existing combination of tractor and attached equipment in order to perform the work task currently to be performed is identified as a first time driving. This also includes the driving of a vehicle group whose composition has been changed during a working day on the same field or the same site in order to perform a new, different work task or the same work task on the field or the site. Changing the work task and / or changing the composition of the vehicle group on the same day and then driving on the same field or the same site again also means the first time driving on the field or the site.

[0008] The driver assistance system can be implemented and arranged in particular to detect the vehicle group leaving the field or site based on the vehicle group crossing a geo-positioned boundary and to initiate at least one action triggered by the driver assistance system based on this. For example, automatic billing of work performed by the vehicle group on the field or site can be initiated as an action.

[0009] In this case, the at least one action to be triggered may include storing changes to machine settings of the tractor and / or the attached equipment and / or changes to the driver profile which are carried out during the processing of the field or site in the database.

[0010] Preferably, the driver assistance system can automatically deduce the composition of the vehicle group based on the work tasks transmitted from the remote data processing system and / or determine or supplement the composition of the vehicle group by manually inputting tasks with the help of the user interface of the driver assistance system. The work tasks can include information about the activities to be performed on the field or site, about the operator, about the field or site (such as name or plot number), about the type of crop to be planted, about the combination of tractor, attached equipment and tractor tires, about route planning, about the ground and working conditions and / or about application data.

[0011] According to a further development, the driver assistance system can be designed and configured to independently communicate bidirectionally with the control units of the tractor and the attached device by means of at least one bus system. This allows the machine settings of the tractor and the attached device to be exchanged independently between them and the driver assistance system.

[0012] Further preferably, the driver assistance system can be embodied and arranged for the operator to manually select machine settings and / or driver profiles that are suggested for the vehicle combination after the vehicle combination has crossed a geographically located boundary of a field or site.

[0013] In particular, the driver assistance system can be implemented and configured to automatically (in particular interactively) generate a handling recommendation for machine settings after the vehicle group has crossed a geographically located boundary of a field or site. This allows for the situation in which no common field-specific data set is available for the tractor and attached equipment and their combination with which the field or site is to be processed. For example, specific machine settings can be loaded from a database for the tractor and attached equipment, which have been stored for the field or site at a previous point in time when the tractor or attached equipment was processed. This also applies analogously to the driver profile to be loaded.

[0014] According to one refinement, the driver assistance system can be implemented and configured to record soil data, harvest data, machine data, attached equipment data, tire data and / or record changes in the driver profile in a georeferenced manner during the processing of the field or site. This can expand the existing data base of at least one database. In addition, the georeferenced recording makes it possible to compile the processing process with regard to traceability and can subsequently be analyzed to increase the efficiency of the future use of the vehicle group.

[0015] For this purpose, the driver assistance system can be configured to transmit recorded changes in soil data, harvesting data, machine data, attached equipment data, tire data and / or driver profiles to a remote data processing system for evaluation and / or storage. In this way, a continuous updating of the data set can be achieved. In addition, this provides the possibility of compiling the completion of work tasks in a field-specific manner, for example for subsequent evaluation of the workflow or settlement.

[0016] The driver assistance system can be implemented and configured in particular to: when a vehicle group is detected for the first time driving on a field or a site for processing, make settings with the help of initial machine settings stored in the at least one database and / or in the control unit of the tractor and the attached equipment, which initial machine settings are specific to historical harvest data and / or land data of the field or site to be processed stored in the at least one database, wherein the combination of the vehicle group consisting of the tractor and the attached equipment does not have corresponding (in particular field-specific) storage of machine settings 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 group, wherein the at least one position sensor can be arranged on the tractor and / or the attached equipment, and / or the at least one position sensor can be a position sensor carried by an operator of the vehicle group.

[0018] Preferably, when the vehicle group drives over a field or a site for the first time, the driver profile and / or the associated machine settings associated with the field or site are loaded from the at least one database, which can be achieved by comparing or reconciling or matching the call-up time with the stored time of the driver profile and / or the associated machine settings of the detected field or site in a time-dependent manner. In this way, machine settings and / or driver profiles can be loaded that, in addition to spatial relevance, also have a time relevance, in particular a seasonal relevance.

[0019] In particular, at least one database may be stored in a data source remote from the vehicle group, wherein the data source remote from the vehicle group is a data processing hardware remote from the vehicle group (in particular a cloud-based data processing system). Basically, the data source remote from the vehicle group may also be a data server remote from the vehicle group, which communicates with the vehicle group via an Internet connection or the like.

[0020] According to another teaching having independent significance according to claim 14, protection is claimed for a vehicle set, which comprises a tractor and an agricultural attachment, wherein the vehicle set is equipped with a driver assistance system. According to this further teaching, it is essential to equip the vehicle set with a driver assistance system according to the first teaching. All embodiments of the first teaching can be referred to as long as they are suitable for describing the agricultural vehicle set as a whole.

[0021] According to another teaching having independent significance according to claim 15, protection is claimed for a method for operating a vehicle group, which includes a tractor and agricultural attachments, wherein the vehicle group is controlled by a driver assistance system assigned to the vehicle group (in particular, a driver assistance system according to the proposal), wherein the driver assistance system is connected to at least one database via a communication unit, in which machine settings of at least one combination of the tractor and the attachments are stored, wherein the driver assistance system detects the first time the vehicle group drives over a field or a field for processing based on the vehicle group crossing a geographically positioned boundary of the field or a field, loads a driver profile and / or the assigned machine settings assigned to the field or a field from the at least one database when the vehicle group drives over the field or a field for the first time, and sets the tractor and / or the attachments according to the loaded driver profile and / or the loaded machine settings. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be further described below with reference to the embodiments shown in the drawings.

[0023] in:

[0024] Figure 1 An agricultural vehicle set is shown schematically and exemplarily; and

[0025] Figure 2 A simplified flow chart is shown by way of example. DETAILED DESCRIPTION

[0026] Figure 1 An agricultural vehicle group 4 is schematically and exemplarily shown, which includes a tractor 1 equipped with a field sprayer (Feldspritze) as an attached device 2. The tractor 1 can be assembled with at least one attached device 2 via at least one device interface. The attached device 2 can be any attached device that can be coupled to the tractor 1 via the device interface in the above-mentioned manner. For example, the agricultural attached device 2 can be a field sprayer, a plow, a baler, a seed drill, or the like as shown in the figure. The tractor 1 and / or the attached device 2 have at least one position sensor 3 for receiving position data provided by a position determination system 21.

[0027] The agricultural vehicle set 4 is equipped with a driver assistance system 5, which is implemented and configured for driving the agricultural vehicle set 4. The driver assistance system 5 has a user interface 6 for inputting and outputting information, a computing unit 7, a storage unit 8, and a sensor assembly 9. In addition to the position sensor 3, the sensor assembly 9 is also equipped with at least one sensor 10, 11 (preferably equipped with a plurality of sensors 10, 11 here) for collecting measured values. Here, the sensor 10 is assigned to the working machine 2, and the sensor 11 is assigned to the attached device 3.

[0028] The driver assistance system 5 is connected to at least one database 13 via a communication unit 12. The communication unit 12 may be a network implemented locally in the vehicle group 4, a mobile wireless network or a W-LAN. The at least one database 13 may be stored in the storage unit 8 of the driver assistance system 5.

[0029] Alternatively or additionally, the at least one database 13 may be stored in a data source remote from the vehicle group. Here, the at least one database 13 may be stored in a storage unit 15 as a data source of a data processing system 14. The data processing system 14 includes a computing unit 16 and a user interface 17.

[0030] The data processing system 14 may be implemented as a farm management system located on suitable data processing hardware in the farm 18. Alternatively, the remote data processing system 14 may be a cloud-based data processing system located at a remote computing center.

[0031] In the at least one database 13, a data set 39 is stored, which has machine settings 20 of at least one combination of tractor 1 and attached equipment 2. In addition, at least one driver profile 19 of an operator of the vehicle group 4 is stored as data set 39 in the at least one database 13.

[0032] The driver assistance system 5 uses a driver profile 19 for its operation and uses an engine setting 20 of the engine set 4 for driving the engine set 4, said driver profile 19 and said engine setting 20 are each loaded from the at least one database 13. The data contained in the driver profile 19 and the engine setting 20 of the engine set 4 will be referred to in Figure 2 Further explanation.

[0033] The tractor 1 and the attachment device 2 can exchange information with each other via a bus system 24. The driver assistance system 5 is designed and configured to independently communicate bidirectionally with at least one control unit 22 of the tractor 1 and at least one control unit 23 of the attachment device 2 via at least one bus system, preferably the bus system 24.

[0034] like Figure 1 It can be further seen that the vehicle group 4 moves along a travel route 29 to a field 25 in order to process it. After processing the field 25, the vehicle group 5 can move along another travel route 30 to another field 26 or another field 40 in order to also process it. These travel routes 29, 30 can be public roads and paths and / or field roads connecting these fields 25, 26 to each other or the like.

[0035] The corresponding fields 25, 26 or the corresponding fields 40 are mapped. The mapping data are available to the driver assistance system 5 or can be provided to the driver assistance system 5. These fields 25, 26 or fields 40 are designed to be closed and have geolocation boundaries 27 as administrative boundaries. Here, the geolocation boundaries 27 of these fields 25, 26 are simplified as rectangles, but they can have different shapes from this. These geolocation boundaries 27 make it possible to distinguish between the positions of the vehicle groups 4 inside and outside the geolocation boundaries 27 or fields 25, 26.

[0036] The driver assistance system 5 is implemented and arranged to detect the first driving of the vehicle group 4 into the field 25, 26 for processing based on the vehicle group 4 crossing the geolocation boundary 27 of the field 25, 26. The crossing of the geolocation boundary 27 for the first driving into the field 25 or field 26 is detected based on the vehicle group 4 passing the entry point 28. For this purpose, the vehicle group 4 can send its position at regular intervals or allow its position to be queried from the outside. This positioning can be carried out based on coordinates, for example, by a positioning system implemented as a mobile radio system at the radio cell level (Funkzellenebene) or by a positioning system 21 implemented as a navigation satellite system.

[0037] In this context, the first travel of a vehicle group 4 through one of these fields 25, 26 means that the agricultural vehicle group 4, when arriving at this field 25, 26 or site 40, travels through this field 25, 26 for the first time in order to perform the work task 32 currently to be performed; the vehicle group 4 is detected for the first time passing the entry point 28 in the existing composition. This also includes a change in the composition of the vehicle group during a working day in order to perform a new and different work task 32 on this field 25, 26 or to perform the same work task 32 while the vehicle group travels through the same field 25, 26 or the same site 40. Changing the work task 32 and / or changing the composition of the vehicle group 4 on the same day and in connection with this passing through the entry point 28 again also means the first travel through this field 25, 26.

[0038] Detecting the first travel on, for example, a field 25 causes the driver assistance system 5 to load a data set 39 of a driver profile 19 assigned to the field 25 and / or a data set 39 of machine settings 20 of the vehicle set 4 assigned to the field 25 from the at least one database 13 when the vehicle set 4 travels on the field 25 for the first time, and to set the tractor 1 and / or the attached equipment 2 according to the loaded driver profile 19 and / or the loaded machine settings 20.

[0039] Figure 2 By way of example, a simplified flow chart is shown, based on which a method for operating the vehicle combination 4 is explained when driving through a field 25 and / or a field 26 for the first time is detected.

[0040] The work order 32 for the vehicle group 4 to process the field 25 and / or the field 26 can be received from the data processing system 14 implemented as a farm management system. If necessary, the operator of the vehicle group can manually process the received work order 32 with the help of the driver assistance system 5. This can preferably be done by an interactive dialog controlled by the driver assistance system 5.

[0041] The work order 32 may contain basic information about the task to be performed, the operator, the client, the field 25, 26 and / or the crop type. In addition, the work order 32 may contain information about the vehicle group 4 (i.e. its composition consisting of the tractor 1 and the attached equipment 2), the route planning, the ground conditions, the environmental conditions and / or the application data. The work order 32 generated by the data processing system 14 can usually be supplemented by the operator of the vehicle group 4 with the help of the driver assistance system 5. The existing work order 32 can be continuously updated by the data processing system 14 so that any changes (such as changes in the route planning or environmental conditions) can be taken into account during the execution of the work order 32.

[0042] In process step 33 , the arrival at the entry point 28 is detected for the first processing of the field 25 within the scope of the given work order 32 . The positioning data required for this are received by the position sensor 3 .

[0043] In process step 33 , the composition of vehicle group 4 can be automatically derived from work tasks 32 transmitted by telematics system 14 and / or can be determined or supplemented by manual input of tasks via a user interface of driver assistance system 5 .

[0044] Additionally or alternatively, in process step 33 , information may be received from control units 22 , 23 of tractor 1 and attachment device 2 , which information may be evaluated by driver assistance system 5 to determine the combination of vehicle group 4 formed by tractor 1 and attachment device 2 .

[0045] In the database 13, field-specific data sets 39 of one or more driver profiles 19 are stored. The at least one driver profile 19 contains information about the name and telephone number of the operator, terminal settings of the tractor 1 and / or the attached equipment 2 (e.g. units, language settings, etc.), comfort settings (e.g. radio configuration or heating, ventilation and air conditioning in the cab of the tractor 1), user identification methods (e.g. by means of profiles, iBeacons, tasks or the like).

[0046] Furthermore, a data set 39 of machine data 34 of one or more tractor vehicles 1 is stored in the database 13. These machine data 34 contain information about vehicle weight, vehicle dimensions, restrictions, drive train, connection interfaces and the like.

[0047] The database 13 contains a data set 39 of attached device data 35 about one or more attached devices 2. These attached device data 35 contain information about the category, type or model, geometry, weight, configuration and / or equipment, power distribution and the like or more about the attached device.

[0048] Furthermore, a data set 39 containing tire data 36 of one or more tires of the tractor 1 is stored in the database 13. These tire data contain information about the dimensions, the load-bearing capacity at different pressures and the like.

[0049] The database 13 also contains a data set 39 of land data 37 for one or more fields 25, 26 or sites 40. These land data 37 contain information about the traction conditions. Information on rolling resistance, soil matrix potential, land pre-compaction, etc.

[0050] Likewise, the database 13 contains a data set 39 of harvesting data 38 about one or more fields 25, 26 or sites 40. These harvesting data 38 can contain process-specific information about the settings of the tractor 1 and / or the attached equipment 2, such as engine pressure, cutting height, baling pressure of a baler as an attached equipment and the like.

[0051] All of the above-mentioned data sets 39 have in common that they are stored in a georeferenced manner in the database 13. These data sets 39 are assigned to individual fields 25, 26. In this case, the stored data sets 39 of the fields 25, 26 vary, in particular, depending on the operator, the tractor 1 and / or the attached equipment 2 and the machine data 34, attached equipment data 35, tire data 36, ​​soil data 37 and / or harvest data 38 associated therewith.

[0052] When the vehicle group 4 drives over the field 25 for the first time, the driver assistance system 5 determines one or more data sets 39 of the driver profile 19 assigned to the field 25 and / or the machine settings 20 of the vehicle group 4 assigned to the field 25 from the machine data 34, the attached equipment data 35, the tire data 36, ​​the soil data 37 and / or the harvesting data 38, said data sets 39 matching the combination of the vehicle group 4 determined in the process step 33 and the information obtained from the work task 32 to be performed on the field 25.

[0053] Before the vehicle combination 4 starts processing the field 25 , 26 , the driver assistance system 5 sets the tractor 1 and / or the attached equipment 2 in a field-specific manner according to the driver profile 19 loaded as data set 39 and / or the machine settings 20 loaded as data set 39 .

[0054] In this case, the data set 39 containing the machine settings 20 includes the control units 22 , 23 and / or actuators of the tractor 1 and the attached device 2 that are automatically actuated by the driver assistance system 5 in order to achieve the optimal settings, as well as instructions for an operator to manually implement the settings on the tractor 1 and the attached device 2 .

[0055] The control unit 22 of the tractor 1 and the automatic control of the actuators include a bus system 24 (preferably an ISO bus system), a controller, a drive engine, a drive train, a power take-off shaft speed, a hydraulic system, an engine pressure, an all-wheel drive, a differential lock, a trailer device, and a tire pressure set by means of a tire pressure control device.

[0056] The control unit 23 of the attachment device 2 and the automatic control of the actuators include a bus system 24 (preferably an ISO bus system), section width control, baling pressure, and height setting of the harvest material receiving device.

[0057] The possible options for automatic control vary depending on the equipment, type and model of the tractor vehicle 1 or the attached equipment 2 .

[0058] The settings to be carried out manually on the tractor 1 may be the ballast, the setting of the trailer arrangement or the like.

[0059] The settings to be carried out manually on the attachment device 2 can be the working depth or cutting height to be set, the setting of the tiller blades or the like.

[0060] The possible options for the settings to be carried out manually also vary depending on the equipment, type and model of the tractor 1 or the attached equipment 2 .

[0061] Driver assistance system 5 is designed and arranged to georeference soil data 37 , harvest data 38 , machine data 34 detected by means of sensors 10 , 11 and / or to record changes in driver profile 19 during processing of field 25 , 26 or site 40 .

[0062] The driver assistance system 5 transmits the recorded changes in the soil data 37 , harvesting data 38 , machine data 34 and / or the driver profile 19 to the remote data processing system 14 for evaluation and georeferenced storage.

[0063] Furthermore, the driver assistance system 5 is designed and arranged to detect the departure of the vehicle group 4 from the field 25, 26 based on the crossing of the geolocation boundary 27 by the vehicle group 4 and to initiate at least one action triggered by the driver assistance system 5 based on this. The departure from the field 25, 26 is detected by the vehicle group 4 passing the exit point 31. Here, the entry point 28 and the exit point 31 can be spatially distant from each other, or they can coincide spatially at one point (as shown by way of example on the field 40 to be processed).

[0064] The at least one action to be triggered may include storing changes to the machine settings 20 of the tractor 1 and / or the attached equipment 2 and / or changes to the driver profile 19 in the database 13 , which changes are carried out during the processing of the field 25 , 26 or site 40 .

[0065] The driver assistance system 5 may have a user interface for an operator to manually select machine settings 20 and / or driver profiles 19 that are suggested after the vehicle combination crosses a geo-located boundary 27 of a field 25 , 26 or site 40 .

[0066] Here and preferably, the driver assistance system 5 can be implemented and set up for automatically (in particular interactively) generating maneuvering recommendations for machine settings after the vehicle group has crossed the geographically located boundary 27 of the field 25, 26 or the site 40. The automatic generation of maneuvering recommendations by the driver assistance system 5 is relevant in the case where there is no common field-specific data set 39 available for the machine settings 20 and / or the driver profile 19 for the tractor 1 and the attached equipment 2 and their combination as the vehicle group 4 with which the field 25, 26 or the site 40 is to be processed. This can occur, for example, in the case of newly purchased tractor 1 and / or attached equipment 2. The same applies to new combinations of existing machines, which have not been used in the field 25, 26 in this new combination until now.

[0067] For example, specific machine settings 20 can be loaded from the database 13 for the tractor 1 and the attached equipment 2, which were stored for the field 25, 26 or the site 40 at a previous point in time when it was processed by the tractor 1 or the attached equipment 2. This also applies analogously to the driver profile 19.

[0068] Therefore, the driver assistance system 5 can be implemented and configured to: when it is detected for the first time that a vehicle group 4 is traveling on a field 25, 26 or a site 40 for processing, it is set with the help 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 attached equipment 2, which initial machine settings are specific to the historical land data 37 and / or harvest data 38 of the field 25, 26 or site 40 to be processed stored in the at least one database 13, wherein the combination of the vehicle group 4 consisting of the tractor 1 and the attached equipment 2 does not have corresponding (especially field-specific) storage of machine settings 20 in the at least one database 13.

[0069] Another aspect is that a comparison or coordination or matching is carried out in terms of time between the detection of the first travel on a field 25, 26 and the time at which one or more field-specific data sets 39 assigned to the relevant vehicle group 4 are stored (also by updating). In this case, when the vehicle group 4 travels on a field 25, 26 or a site 40 for the first time, the driver profile 19 assigned to this field 25, 26 or site 40 and / or the assigned machine settings 20 are loaded from the at least one database 13, which can be achieved by comparing or coordinating or matching the call-up time (corresponding to the time at which the vehicle group 4 is first traveled to be set) with the time at which the driver profile 19 assigned to the field 25, 26 or site 40 detected here and / or the assigned machine settings 20 of the vehicle group 4 were previously stored in a time-dependent manner.
