Definitions
- the technical field relates to a method for carrying out instructions for action using a working machine, and a control unit which is set up to carry out the method for carrying out instructions for action, and a working machine with such a control unit.
- the invention relates to a method for carrying out instructions with a working machine.
- the work machine can be a truck or a construction machine, such as a wheel loader, an excavator, or a bulldozer.
- An instruction for action, or event can be an instruction to perform an action.
- the instruction can consist of commands to carry out the action.
- the action can be an action to be performed with the work machine. For example, lifting a shovel of the working machine can be carried out as an action.
- the method can be performed iteratively.
- the method can be carried out at periodic intervals.
- the method can be used to carry out repetitive instructions. In particular, the method can be used to carry out location-dependent and repetitive instructions.
- a first action instruction can always be executed by the method at a first location when the work machine is at the first location.
- the method allows the first instruction to be carried out automatically at the first location.
- the method has a step of reading in information on instructions for action.
- the information on instructions for action can be read in by a service tool, for example by a central service tool. If the method is executed iteratively, the step of reading in can only take place in the first step of the method. Alternatively or additionally, the step of reading in can always take place when information on instructions for action has been updated, for example by the central service tool.
- information on one position and one orientation is read. The position of the instruction can describe the place where the instruction is to be carried out.
- each instruction can be clearly assigned a position at which it is to be carried out.
- information on an orientation of the handling instruction can be read.
- Information about the orientation of the handling instruction can be used to execute the handling instruction by executing the handling instruction when the work machine moves in the orientation of the handling instruction to the handling instruction.
- information about a position can be read in for an instruction, but no information about an orientation. In other words, such an instruction can be approached regardless of the direction.
- the position information may be in two-dimensional coordinate information and the orientation information in degrees in a global and non-moving stationary frame of reference.
- the method has a step of detecting a position of the working machine.
- the step of detecting can occur in each iterative step of executing the method. For example, a first position of the working machine can be detected at a first time and a second position, different from the first position, of the working machine can be detected at a second, later time.
- the method further includes a step of determining a change in the position of the work machine. The step of determining the change in position of the work machine may be based on the sensed position of the work machine. In particular, the step of determining the change in position of the Working machine based on positions of the working machine detected at least at two different points in time.
- the method further includes a step of determining a travel direction of the work machine based on the change in the position of the work machine.
- the step of determining the direction of travel can thus take place as a function of positions of the working machine that change over time.
- the method also has a step of determining whether the orientation of the action instruction corresponds to the direction of travel of the work machine within a first tolerance.
- the orientation can be compared with the direction of travel of the work machine for each individual instruction for which an orientation has been read.
- the first tolerance can be specified in degrees and specify, for example, that a deviation of up to 10° is permissible for a match between the orientation of a respective instruction and the direction of travel. If the direction of travel of the working machine cannot be determined precisely enough because the speed of the working machine is too slow, the step of determining whether the alignment matches the direction of travel can be skipped or this step can be evaluated positively for each instruction.
- the step of determining can only take place for the instructions for which an orientation has been read. This determination step can be skipped for instructions without orientation.
- the method also has a step of determining an absolute distance between the work machine and the respective instruction.
- the step of determining the absolute distance takes place for instructions with an alignment to the direction of travel that differs by no more than the first tolerance. In other words, the step of determining the absolute distance for all handling instructions with an orientation that differs from the direction of travel of the work machine by more than the tolerance can be avoided. If the direction of travel of the work machine could not be determined due to the vehicle speed being too slow, the step of determining the absolute distance for all instructions for action can be carried out.
- the step of determining the absolute distance can be given for an instruction for which no alignment has been read in and is direction-independent.
- the absolute distance can be the distance, defined in absolute and stationary coordinates, between the 2D coordinates of the position of each action instruction and the detected position of the work machine. The absolute distance is determined based on the position of the work machine and the respective position of the operating instruction.
- the method also has a step of determining a relative distance between the working machine and the respective operating instruction in the direction of travel of the working machine and transversely to the direction of travel of the working machine.
- the step of determining the relative distance takes place for instructions with an absolute distance that is smaller than a first predefinable value.
- the first predefined value can represent a passive search window, which can be constant or changeable. Determining the relative distance can be avoided for all instructions for action with an absolute distance that is at least equal to or greater than the first predefinable value. In other words, the relative distance can be determined for all instructions for action that lie in the passive search window.
- the step of determining the relative distance takes place based on the positions of the respective instruction, the position of the working machine and the direction of travel of the working machine.
- the method also has a step of activating an external control device for executing the respective instruction.
- the actuation step takes place for instructions for action with a relative distance which is smaller than a second predefinable value.
- the second predefined value can be an active search window.
- the active search window can be circular or rectangular.
- the position of the respective instruction can be singular, in other words it can only consist of one point in space. Alternatively, the position of the instruction can consist of an area, for example a circular area, around a singular central point of the instruction.
- Driving can be done when the position and, if necessary the area around the position of the handling instruction overlaps with the active search window of the working machine. In other words, the actuation can take place for all instructions whose position lies in the active search window or whose area intersects the active search window.
- a method is thus advantageously shown with which action instructions can be carried out as a function of the position.
- the method can advantageously be used to check which instructions are to be carried out in order to carry out the most efficient execution possible.
- the sequence of the steps of the method can ensure that the necessary steps of determining the absolute distance and the relative distance are only carried out for those instructions that are relevant due to the alignment and the position of the instruction and the direction of travel of the working machine, i.e can be triggered. This can reduce the computational burden of the steps by avoiding unnecessary steps.
- the triggering can be designed to be direction-dependent and the computing effort can also be reduced by using this directional component at an early stage.
- the action instruction can be one of activating a transmission, operating an implement, activating a drive motor, activating a steering system and activating brakes.
- the actuation of the transmission can be an actuation of a differential lock and, alternatively or additionally, an engagement of a gear.
- the actuation of the working device can be, for example, lifting a shovel in an excavator as the working machine.
- Controlling the drive motor can, for example, include controlling the drive motor with a minimum or maximum torque and alternatively or additionally with a minimum or maximum power.
- the activation of the drive motor, steering and brakes can describe an instruction for an autonomous driving function, a speed limit, a driving strategy, such as driving uphill or downhill.
- the handling instruction can be setting a parameter in a memory.
- a parameter can be set which is used to compare with sensor measurement data.
- a distance sensor can be influenced with a comparison parameter that can be parameterized by the action instruction in such a way that the sensor can be set to be more or less sensitive based on the action instruction.
- a distance sensor can be set to be more sensitive when driving in certain sectors, shown as the position of an instruction.
- a method can thus be used to carry out different instructions that are to be carried out at specific positions.
- the transmission can always be controlled in the same position, namely at the foot of the hill, so that a lower gear is engaged.
- a user of the work machine can thus be relieved in that the repetitive action of engaging a low gear at the foot of the mountain can be automatically taken over by the method.
- the method can also have a step of determining whether the respective instruction for action is in the direction of travel or against the direction of travel of the working machine.
- This step of determining can take place based on the direction of travel of the work machine and the respective position of the instruction. In other words, it can be determined individually for each action instruction whether it is in the direction of travel or against the direction of travel of the working machine. This can be done by dividing a work machine coordinate system into two areas. A front area can extend from the working machine in the direction of travel, and a rear area can extend from the working machine in the opposite direction to the working machine. Each instruction that is in the front area can therefore be in the direction of travel, and each other instruction can be opposite to the direction of travel.
- This step of determining can be carried out qualitatively, and a transformation of the coordinates of the positions of the instructions for action into the work machine coordinate system can be avoided.
- the step of determining the absolute distance can take place for a respective action instruction in the direction of travel of the working machine.
- the step of determining the absolute distance can take place for all instructions for action in the front area.
- the step of determining the absolute distance can be used for all instructions against the direction of travel be avoided.
- the step of determining the absolute distance can only be carried out for those instructions for action which are both in the direction of travel and their respective orientation within of the first tolerance coincides with the direction of travel.
- the method can thus ensure that the further steps of determining the absolute and the relative distance are only carried out for the handling instructions, which are in the direction of travel and can therefore be approached and thus executed. This can save computing capacity when executing the method.
- the method can also have a step of determining a respective direction vector in relation to the working machine for a respective instruction.
- the step of determining a direction vector in each case can take place for all instructions whose orientation corresponds to the direction of travel within the first tolerance.
- the step of determining a respective direction vector for all instructions that lie in the direction of travel of the work machine can take place.
- the step of determining the direction vector can be based on the position of the working machine and the position of the respective instruction.
- the step of determining the absolute distance for a respective instruction can take place if the direction vector of the respective instruction for action matches the direction of travel of the work machine within a second tolerance.
- the step of determining the absolute distance can take place for all instructions for action whose respective direction vector corresponds to the direction of travel within the second tolerance.
- a direction vector of an instruction can be the relative direction from the position of the work machine to the position of the respective instruction.
- a direction vector for an instruction can be obtained by subtracting the position of the work machine from the position of the respective instruction in stationary coordinates.
- the step of determining the absolute distance can only be carried out for those handling instructions whose directional vectors match the direction of travel within the second tolerance. In other words, the step of determining the absolute distance can only take place for those instructions for action in the direction of which the working machine is moving.
- the method can also have a step of storing information about an instruction.
- the information on an instruction can be stored in a storage medium.
- the information can be one of the respective directional vector of the handling instruction, the absolute distance between the working machine and the handling instruction, the relative distance between the working machine and the handling instruction, whether the handling instruction is in the direction of travel of the working machine and whether the orientation of the handling instruction is no more than that first tolerance is different from the direction of travel of the working machine.
- the step of storing can include the steps of determining direction vectors, determining the absolute distances and determining the relative distances, and determining whether the instruction for action is in the direction of travel and whether the orientation of the instruction for action corresponds to the direction of travel, store specific values.
- all of the specific information relating to all instructions for action can be stored for each iteration step. This information can then be accessed in a later iteration step.
- the method can be used iteratively for executing the instructions, as a result of which the individual computing steps can access previously determined values and the computing effort in each iteration step can thus be minimized and the accuracy of the method can be increased.
- information on instructions for action can be in the form of a list.
- a first entry in the list can describe a first instruction and a second entry in the list can describe a second instruction.
- the list may have been stored in the step of storing information of the action instruction.
- the method can also include a step of sorting the list of information on instructions for action. In other words, the sorting step can take place in an iteratively next step of the method as a function of the step of storing information of the instruction from a previous step of the method.
- Entries in the action instruction list may be sorted depending on information from the step of determining the directional vector, absolute distance, relative distance, whether the orientation matches the direction of travel, and whether the action instruction is in the direction of the direction of travel.
- the order of the entries in the instructions can be changed, specifically as a function of the information on instructions.
- a first instruction can be sorted at the chronological start of the list, for which all steps of the determination have been carried out, for which a relative distance has therefore also been determined.
- a second instruction can then be sorted chronologically, to which an absolute but no relative distance has been determined.
- the step of determining whether the respective orientation is no more than the first tolerance different from the direction of travel may based on the list sorted in the sorting step.
- the step of determining whether the action instruction is in the direction of travel can take place based on the list sorted in the sorting step.
- the method when the method is carried out iteratively, information that has already been determined and stored for instructions on how to act can be accessed.
- the further determination in the next iterative step of the method can thus initially take place in the chronological order of the list and thus for the more relevant instructions for action.
- the method for the instructions for action sorted chronologically further up in the list can thus preferably be used in order to carry out these instructions for action.
- the method can also have a step of reading in information about a new instruction.
- a new action instruction can be a new event, for example a new action at a new position.
- the step of reading in can be confirmed by a user in a step of confirmation.
- the user can confirm the instruction via a user interface of the work machine, for example a touch display. For example, it can be suggested to the user to save the new instruction to engage a lower gear when driving uphill. The user can confirm this in the confirming step via the user interface.
- the user can enter new instructions for action himself via the user interface and confirm them at the same time.
- the step of determining whether the respective orientation differs from the direction of travel of the work machine by no more than the first tolerance can be carried out based on the new instruction for action confirmed in the step of confirming.
- the step of determining whether the instruction in the direction of travel, based on the new instructions for action confirmed in the confirmation step can be carried out.
- the step of determining the direction vector of the new instruction, of determining the absolute distance and the relative distance can be based on the confirmed new instruction.
- the method can also be used for newly appearing instructions.
- the method can also have a step of driving the user interface with information on instructions for action.
- information on instructions for action can be displayed to the user via the touch display of the working machine.
- the step of controlling the user interface can be carried out based on the information on instructions for action stored in the step of storing.
- the specific directional vectors, the specific absolute distances and the specific relative distances, whether the action instruction is in the direction of travel and whether its alignment is not different from the direction of travel can be displayed.
- information on the actual action of the action instruction can be displayed, for example the action lifting a shovel or the action engaging a gear.
- the method can thus be used to display all available information on instructions for action to the user of the work machine.
- the method can also have a step of detecting a user input via the user interface.
- the user input can include confirmation via the touch display.
- the control step can be based on the user input detected in the detection step. In other words, only the instructions for action that have been confirmed and approved by the user can be executed.
- stored information relating to at least one instruction can be deleted by user input and alternatively or additionally manipulated. So If the user thinks that an obsolete instruction has been saved, the user can delete it.
- the method can thus advantageously also be used for safety-critical instructions, in that all safety-critical instructions can only be executed when they have been released by the user. Furthermore, the user can manipulate the list in such a way that only instructions relevant to him are found in the list.
- the step of determining the relative distance in the direction of travel and transverse to the direction of travel can only be carried out for the instructions for which the absolute distance does not increase over time in the step of determining the absolute distance between the working machine and the respective instruction has.
- the step of determining the relative distance can be avoided since the work machine effectively moves away from the instruction for action and determining the relative distance can therefore be obsolete.
- a computationally intensive step of determining the relative distance can thus be avoided for all the instructions for which the absolute distance increases when the method is executed iteratively and the instructions are therefore not relevant.
- the second predefinable value can be dependent on a driving state of the working machine.
- the driving state can describe, for example, a speed and, alternatively or additionally, an acceleration of the working machine.
- the second predefinable value, or the active search window can thus be greater when the working machine is moving at a high speed than when it is moving at a slower speed.
- the second predefinable value may be greater, particularly in the transverse direction, than at a lower transverse acceleration, for example when the machine is traveling straight ahead.
- the method can thus be used for different driving states of the working machine to carry out instructions. If the work machine drives faster, an instruction can be executed at a relative distance, for example, which would not yet be executable at a lower speed.
- the invention relates to a control device which is set up to carry out the method according to an embodiment according to the preceding aspect of the invention.
- a further aspect relates to the work machine with such a control device according to the previous aspect.
- the work machine can have a GPS receiver for determining the position of the work machine.
- the work machine can have an interface for reading in information on instructions for action and on new instructions for action.
- the work machine can have the user interface, such as the touch display, for displaying information about the instructions for action by driving.
- the user interface can also be used to capture the user input and to confirm the new instruction for action.
- the work machine can have the transmission for executing the instructions for action by activation.
- the transmission can have a differential lock.
- FIG. 1 schematically shows steps of a method for carrying out instructions according to an embodiment.
- FIG. 2 schematically shows components of a working machine and instructions for action around the working machine.
- FIG. 1 schematically shows steps of a method for carrying out instructions 4, 6, 8, 9 according to an embodiment.
- the instructions for action 4, 6, 8, 9 are shown in FIG.
- the work machine 2 has a control unit 10 which is set up to carry out the method.
- the work machine 2 has an interface 3 which is set up to read in information on the instructions for action 4, 6, 8 in a reading SO step.
- the work machine 2 has a GPS receiver 14 for detecting a position of the work machine 2 S3 .
- Control unit 10 is set up to determine a change in the position of working machine 2 at at least two different points in time in a determining step S3.1 as a function of step S3 of detecting the position of working machine 2 .
- control unit 10 is set up to determine a direction of travel 2a of working machine 2 based on the change in the position of working machine 2 determined in step S3.1.
- the direction of travel 2a shown in FIG. 2 points to the right.
- the control unit 10 is set up to carry out a step of determining S5.1 whether an orientation 4a, 6a of the action instruction 4, 6 corresponds to the direction of travel 2a within a first tolerance.
- the alignments 4a, 6a were read in the reading step SO. As shown in FIG. 2, some instructions for action 4, 6 each have an orientation 4a, 6a. The orientations 4a, 6a shown point to the right. Some instructions 8, 9 are direction-independent and have no orientation. No alignment for the instructions 8 was read in the reading step SO. The alignments 4a, 6a match the direction of travel 2a of the working machine 2 within the first tolerance.
- the control device 10 is also set up to carry out a step of determining S5.2 whether the action instruction 4, 6, 8 is in the direction of travel 2a. In the embodiment shown in FIG. 2, instructions 4, 6 are in the direction of travel 2a, and instructions 8 are opposite to the direction of travel 2a.
- Control unit 10 is also set up to determine a step of determining S6 one direction vector for each instruction 4, 6.
- the respective direction vector is determined relative to the position of the working machine 2 based on the position of the working machine 2 and the respective position of the instruction 4, 6.
- the step of determining S6 takes place for all instructions 4, 6 whose orientation 4a, 6a matches the direction of travel 2a within the first tolerance and which lie in the direction of travel 2a.
- the control unit 10 is set up to carry out a step of determining S7 an absolute distance between the work machine 2 and an instruction 4, 6 in each case.
- the step of determining S7 takes place for all instructions 4, 6 with a directional vector which corresponds to the direction of travel of the working machine 2 within a second tolerance.
- the instructions for action 4 lie within the second tolerance of the direction of travel 2a of the working machine 2
- the instruction for action 6 lies outside of this second tolerance of the direction of travel 2a of the working machine 2 .
- the action instruction 6 is too transverse to the direction of travel 2a of the work machine 2.
- the step of determining S7 is therefore not carried out for the action instruction 6, and incidentally also not for the action instruction 8. This saves computing capacity.
- the control unit 10 is set up to carry out a step of determining S8 a relative distance between the work machine 2 and the respective action instruction 4 .
- the step of determining S8 takes place for the action instruction 4 since the absolute distance between the position of the action instruction 4 and the position of the working machine 2 is smaller than a first predefinable value.
- the first predefinable value is described by a passive search window 16 shown in FIG.
- the action instruction 4 is passive Search window 16. This saves computing power, since the relative distance does not have to be determined for instructions 6, 8.
- the control unit 10 is also set up to carry out a step of activating S9 an external control unit (not shown) for executing the instruction 4 .
- Activation S9 takes place for action instruction 4 since the relative distance is smaller than a second predefinable value.
- the second predefinable value is described by an active search window 18 .
- the action instruction 4 is in the active search window 18.
- the action instruction 4 includes engaging a gear of a transmission of the working machine 2.
- Control unit 10 is set up to carry out a storage step S10.
- the storage S10 takes place depending on the steps of determining S5.1, S5.2, S6, S7 and S8. All determined directional vectors, absolute distances and relative distances, and whether the alignment 4a, 6a is in the direction of travel 2a and whether the instructions for action 4, 6, 8 are in the direction of travel 2a, are stored in a storage medium that is not shown further.
- the control unit 10 is set up to control a user interface 12, for example a touchscreen in the exemplary embodiment shown, in a control step S11.
- Activation S11 takes place with information on instructions 4, 6, 8. All specific values, such as directional vectors, absolute distances and relative distances, are displayed. The driver can thus find out all the information about all instructions for action 4 , 6 , 8 via the user interface 12 .
- the method also has a step of detecting S12 a user input via the user interface 12 .
- the detection step S12 takes place as a function of the actuation step S11. In other words, information is displayed to the user in step S11 and is confirmed by the user in step S12. Thus, for a safety-critical instruction 4, the user can enable activation S9 in step S12.
- the method also has a step of sorting S2 a list of information on instructions for action 4, 6, 8.
- the step of sorting S2 takes place as a function of the step of storing S10 information on instructions for action in an iteratively preceding execution step of the method. Furthermore, the step of sorting S2 takes place as a function of the step of detecting S12 the user input.
- the user can delete an instruction 4, 6, 8, and the sorting step S2 then takes place without this deleted instruction 4, 6, 8.
- the sorting step S2 then takes place without this deleted instruction 4, 6, 8.
- 6, 8 Entries for the instructions 4, 6, 8 sorted according to their relevance, depending on the directional vectors and distances.
- the step of determining S5.1 and the step of determining S5.2 in the next iterative step of the method depends on the step of sorting S2. Furthermore, steps S6-S9 depend on the sorted list.
- the method also has a step of reading in S1 a new action instruction 9 .
- the reading in S1 takes place via the interface 3.
- a step of a confirmation S1.1 the new handling instruction 9 is confirmed by the user via the user interface 12 via the touch display.
- the new instruction 9 is thus added to the existing list of instructions 4, 6, 8 by the user confirming S1.1.
- An iterative next step of determining S5.1 and determining S5.2 then takes place for all instructions 4, 6, 8, 9. Steps S6-S9 are also dependent on the sorted list.
