[0010] Embodiments of this disclosure will be described below with reference to the drawings. In each drawing, the same or corresponding components are given the same reference numerals, and their descriptions will be omitted as appropriate.

[0011] (Configuration of the work machine 100) Figure 1 is a schematic diagram showing the configuration of a work machine 100 according to an embodiment of the present disclosure. The work machine 100 operates at a construction site and performs construction work on materials such as soil and sand. The work machine 100 according to an embodiment of the present disclosure is a hydraulic excavator. However, the work machine of the present disclosure may be other work machines such as a dump truck, wheel loader, or motor grader. The work machine 100 comprises a traveling body 110, a rotating body 120, a work machine 130, and an operator's cab 140.

[0012] The traveling body 110 supports the work machine 100 so that it can move. The traveling body 110 is equipped with two tracks 111a and 111b on the left and right sides, and two travel motors 112 for driving each track 111a and 111b. The slewing body 120 is supported by the traveling body 110 so that it can slewing around a pivot point.

[0013] The work implement 130 is driven by hydraulics. The work implement 130 is supported on the front of the slewing body 120 so as to be movable in the vertical direction. The operator's cab 140 is a space for the operator to sit in and operate the work machine 100. The operator's cab 140 is located on the left front of the slewing body 120. In this embodiment, as shown in Figure 1, the vertical, horizontal, and longitudinal directions are defined with respect to the slewing body 120. The part of the slewing body 120 to which the work implement 130 is attached is called the front. Furthermore, with respect to the slewing body 120, the part opposite the front is called the rear, the left side is called the left side, and the right side is called the right side.

[0014] (Configuration of the rotating body 120) The slewing body 120 includes an engine 121, a hydraulic pump 122, a control valve 123, a slewing motor 124, and the like. The engine 121 is the prime mover that drives the hydraulic pump 122. The engine 121 is an example of a power source. In this embodiment, the engine 121 is a diesel engine.

[0015] The hydraulic pump 122 is a variable displacement pump driven by the engine 121. The hydraulic pump 122 supplies hydraulic fluid to multiple actuators via a control valve 123. The multiple actuators include a boom cylinder 131C, an arm cylinder 132C, a bucket cylinder 133C, a travel motor 112, and a slewing motor 124. The control valve 123 controls the flow rate of hydraulic fluid supplied from the hydraulic pump 122.

[0016] The slewing motor 124 is driven by hydraulic fluid supplied from the hydraulic pump 122 via the control valve 123, causing the slewing body 120 to rotate.

[0017] (Configuration of work machine 130) The work machine 130 comprises a boom 131, an arm 132, a bucket 133, a boom cylinder 131C, an arm cylinder 132C, and a bucket cylinder 133C.

[0018] The base end of the boom 131 is attached to the slewing body 120 via a boom pin P1. The arm 132 connects the boom 131 and the bucket 133. The base end of the arm 132 is attached to the tip of the boom 131 via an arm pin P2. The bucket 133 has a blade for excavating soil and other materials and a storage section for collecting the excavated soil. The base end of the bucket 133 is attached to the tip of the arm 132 via a bucket pin P3.

[0019] The boom cylinder 131C is a hydraulic cylinder for driving the boom 131. The base end of the boom cylinder 131C is attached to the slewing body 120. The tip end of the boom cylinder 131C is attached to the boom 131. The arm cylinder 132C is a hydraulic cylinder for driving the arm 132. The base end of the arm cylinder 132C is attached to the boom 131. The tip end of the arm cylinder 132C is attached to the arm 132. The bucket cylinder 133C is a hydraulic cylinder for driving the bucket 133. The base end of the bucket cylinder 133C is attached to the arm 132. The tip end of the bucket cylinder 133C is attached to the link member connected to the bucket 133.

[0020] (Example camera configuration) The rotating body 120 is equipped with multiple cameras 126 (front camera 126A, left-side camera 126B, rear camera 126C, and right-side camera 126D) that capture images of the area around the work machine 100. The front camera 126A is located inside the operator's cab 140. The front camera 126A, left-side camera 126B, rear camera 126C, and right-side camera 126D are collectively referred to as multiple cameras 126. Alternatively, instead of multiple cameras 126, or in conjunction with multiple cameras 126, a single omnidirectional camera may be used, for example. The standard display unit 206, described later, displays overhead images and single-camera images based on the images (single-camera images) captured by each camera 126.

[0021] (Configuration of the 140 driver's cab) A door 141 for the operator to board is provided on the left side of the driver's cab 140. Figure 2 is a diagram showing the internal configuration of the driver's cab 140 according to the embodiment of this disclosure. Figure 3 is a diagram showing the positional relationship between the standard display unit 206 and the extended display unit 207 inside the driver's cab 140 according to the embodiment of this disclosure. However, some components are omitted from the illustration in Figure 3. Inside the driver's cab 140 are a driver's seat 142, an operating device 143, a standard display unit 206, an extended display unit 207, etc. The standard display unit 206 (or a configuration combining the standard display unit 206 with the standard display control unit 2012 described later) is one example of the configuration of the "first display device" of this disclosure. The extended display unit 207 (or a configuration combining the extended display unit 207 with the extended display control unit 2015 described later) is one example of the configuration of the "second display device" of this disclosure. In the examples shown in Figures 2 and 3, a standard display unit 206 and an extended display unit 207 are provided in the driver's cab 140, but the extended display unit 207 is not required. In other words, the work machine 100 of this embodiment can be configured with models equipped with both a standard display unit 206 and an extended display unit 207, and models equipped with only a standard display unit 206. Furthermore, the extended display unit 207 can be added later to models equipped with only a standard display unit 206.

[0022] The operating device 143 is a device for driving the traveling body 110, the slewing body 120, and the work implement 130 by manual operation by the operator. The operating device 143 comprises a left operating lever 143LO, a right operating lever 143RO, a left foot pedal 143LF, a right foot pedal 143RF, a left traveling lever 143LT, a right traveling lever 143RT, and a locking lever 143LL. The left operating lever 143LO is located on the left side of the driver's seat 142. The right operating lever 143RO is located on the right side of the driver's seat 142.

[0023] The left control lever 143LO is an operating mechanism for, for example, the rotation of the slewing body 120 and the digging / dumping of the arm 132. Specifically, for example, when the operator of the work machine 100 pushes the left control lever 143LO forward, the arm 132 performs a dumping operation. Also, when the operator of the work machine 100 pushes the left control lever 143LO backward, the arm 132 performs an digging operation. Also, when the operator of the work machine 100 pushes the left control lever 143LO to the right, the slewing body 120 rotates to the right. Also, when the operator of the work machine 100 pushes the left control lever 143LO to the left, the slewing body 120 rotates to the left. For example, when the left control lever 143LO is pushed forward or backward, the slewing body 120 rotates to the right or left, and when the left control lever 143LO is pushed left or right, the arm 132 performs an digging operation or a dumping operation.

[0024] The right-hand control lever 143RO is an operating mechanism for, for example, performing digging / dumping operations of the bucket 133 and raising / lowering operations of the boom 131. Specifically, when the operator of the work machine 100 pushes the right-hand control lever 143RO forward, the boom 131 is lowered. When the operator of the work machine 100 pushes the right-hand control lever 143RO backward, the boom 131 is raised. When the operator of the work machine 100 pushes the right-hand control lever 143RO to the right, the bucket 133 is dumped. When the operator of the work machine 100 pushes the right-hand control lever 143RO to the left, the bucket 133 is dug. For example, when the right-hand control lever 143RO is pushed forward or backward, the bucket 133 may perform a dumping or digging operation, and when the right-hand control lever 143RO is pushed left or right, the boom 131 may perform a raising or lowering operation.

[0025] Furthermore, the left operating lever 143LO is equipped with five push-button switches BSWL1 to 5. Note that push-button switch BSWL5 is located on the back side of the left operating lever 143LO as viewed in the figure. Similarly, the right operating lever 143RO is equipped with five push-button switches BSWR1 to 5. Note that push-button switch BSWR5 is located on the back side of the right operating lever 143RO as viewed in the figure. Additionally, one or more of the multiple push-button switches may be wheel buttons. For example, the number of push-button switches provided on the left operating lever 143LO and the right operating lever 143RO may be one or more. In the example shown in Figure 2, push-button switches BSWL4 and BSWR4 have the functions of both a push-button switch and a wheel button. In this embodiment, push-button switch BSWL1 is used, for example, as an operator's input to confirm that the function setting for the push-button switch has been confirmed. Push-button switches BSWL1 to 5 and BSWR1 to 5 are examples of the configuration of the "operator" in this disclosure. The left operating lever 143LO and the right operating lever 143RO are examples of the configuration of the "operating levers" in this disclosure. When referring to the push-button switches BSWL1-5 and BSWR1-5 collectively, they are referred to as multiple push-button switches BSW or simply as push-button switches BSW. In the display images shown in the operation examples described later, the push-button switches BSW are referred to as lever switches.

[0026] Furthermore, each of the multiple push-button switches (BSWs) can be assigned a function selected by the operator from among several functions, such as horn, windshield washer, front windshield wiper, auto deceleration, straight-ahead driving, and single-camera image switching (described later). When a push-button switch (BSW) is pressed, the function assigned to that push-button switch (BSW) is executed. For example, if the horn function is assigned to a push-button switch (BSW), pressing that push-button switch (BSW) will sound the horn. In this embodiment, the selection of such functions is performed using the standard display unit 206 or the extended display unit 207, based on input operations on one or more images (hereinafter referred to as "selection images") for function selection displayed by the standard display unit 206 or the extended display unit 207. However, if only the standard display unit 206 is provided, the functions to be assigned to the multiple push-button switches (BSWs) are selected using the standard display unit 206, and if both the standard display unit 206 and the extended display unit 207 are provided, the functions to be assigned to the multiple push-button switches (BSWs) are selected using only the extended display unit 207. In this case, if both the standard display unit 206 and the extended display unit 207 are provided, the standard display unit 206 will not display the selected image. In other words, if both the standard display unit 206 and the extended display unit 207 are provided, the selected image will be displayed on the extended display unit 207.

[0027] Furthermore, the types of functions that can be selected from the selection images displayed by the standard display unit 206 are different from the types of functions that can be selected from the selection images displayed by the extended display unit 207. Functions that can be selected from the selection images displayed by the standard display unit 206 are also called standard functions. For example, if multiple functions that can be assigned include functions that can only be used when the extended display unit 207 is provided (hereinafter also referred to as extended functions), the extended functions cannot be selected from the selection images displayed by the standard display unit 206. Note that the selection images displayed by the extended display unit 207 may also include standard functions. Examples of extended functions include displaying a wide-area map, determining automatic rotation teaching, selecting automatic rotation teaching, and selecting the design surface directly below the cutting edge. Displaying a wide-area map is a function that displays a wide-area map on the extended display unit 207. Automatic rotation teaching determination and automatic rotation teaching selection are functions that record the operations of the rotating body 120 and work implement 130 performed manually by the operator, and when automatically reproducing the recorded operations of the rotating body 120 and work implement 130, select and determine the recorded data (or a function that directly displays the screen for selecting and determining the data without having to navigate through the menu hierarchy). Selection of the design surface directly below the cutting edge is a function that determines the design surface (target surface after excavation) when performing automatic excavation control (or a function that directly displays the screen for making the determination without having to navigate through the menu hierarchy).

[0028] The left foot pedal 143LF is located on the left side of the floor in front of the driver's seat 142. The right foot pedal 143RF is located on the right side of the floor in front of the driver's seat 142. The left travel lever 143LT is pivotally supported by the left foot pedal 143LF, and the tilt of the left travel lever 143LT is linked to the downward movement of the left foot pedal 143LF. The right travel lever 143RT is pivotally supported by the right foot pedal 143RF, and the tilt of the right travel lever 143RT is linked to the downward movement of the right foot pedal 143RF.

[0029] The left foot pedal 143LF and the left travel lever 143LT correspond to the rotational drive of the left track 111a of the vehicle 110. Specifically, when the operator of the work machine 100 pushes the left foot pedal 143LF or the left travel lever 143LT forward, the left track 111a rotates in the forward direction. Also, when the operator of the work machine 100 pushes the left foot pedal 143LF or the left travel lever 143LT backward, the left track 111a rotates in the reverse direction.

[0030] The right foot pedal 143RF and the right travel lever 143RT correspond to the rotational drive of the right track 111b of the vehicle 110. Specifically, when the operator of the work machine 100 pushes the right foot pedal 143RF or the right travel lever 143RT forward, the right track 111b rotates in the forward direction. Also, when the operator of the work machine 100 pushes the right foot pedal 143RF or the right travel lever 143RT backward, the right track 111b rotates in the reverse direction.

[0031] The lock lever 143LL is a safety device provided to prevent the operator from unintentionally operating actuators such as the work implement 130 when the machine is not in operation. The lock lever 143LL is positioned along the side of the left console box 143LC, which is erected to the left of the driver's seat 142, and is rotatable between a locked position and an unlocked position. In Figure 4, the lock lever 143LL shown by the solid line is in the locked position, and the lock lever 143LL shown by the dashed line is in the unlocked position. Hereafter, the locked position will also be referred to as the locked state of the lock lever 143LL (also indicated as LL lock in the drawings), and the unlocked position will also be referred to as the released state of the lock lever 143LL (also indicated as LL released in the drawings). When the lock lever 143LL is in the locked position, the control of the hydraulic fluid by the control valve 123 is stopped. Also, when the lock lever 143LL is in the locked position, the switch LL-SW, which operates in conjunction with the lock lever 143LL, is turned on.

[0032] When the lock lever 143LL is in the locked position, it rotates to a position where it is hidden on the side of the left console box 143LC of the driver's seat 142, that is, out of the passage between the door 141 and the driver's seat 142, and locks there. This allows the operator to move between the door 141 and the driver's seat 142. On the other hand, when the lock lever 143LL is in the unlocked position, it rotates to a position tilted forward so as to block the passage between the driver's seat 142 and the door 141, and locks there. This prevents the operator from leaving the driver's cab 140 while actuators such as the work equipment 130 are operational, as the lock lever 143LL obstructs the operator's entry and exit from the driver's seat 142 when the lock lever 143LL is in the unlocked position. The on / off state of the switch LL-SW, which operates in conjunction with the lock lever 143LL, is monitored, for example, by the work equipment control unit 2013, which will be described later.

[0033] The standard display unit 206 is, for example, a touch panel. The standard display unit 206 is an input / output device that integrally configures an input unit 206I that accepts input operations by touching the display screen 206S with a fingertip or an input pen, and an output device that displays an image on the display screen 206S. The standard display unit 206 is controlled by the standard display control unit 2012, which will be described later, and displays information related to the work machine 100 on the display screen 206S. The information related to the work machine 100 that the display screen 206S displays includes, for example, information representing the operating status of the work machine 100, information representing the setting status and operation status, and image information representing the surroundings of the work machine 100 based on moving images, still images, etc., captured by multiple cameras 126. In this embodiment, "information" refers to the content that is transmitted, and includes image information that represents the content as an image, numerical information that represents the content as a numerical value, etc. Also, in this embodiment, the vertical and horizontal directions of the display screen 206S are as shown in Figure 2. Furthermore, in this embodiment, the display screen 206S has a rectangular shape with its longitudinal direction being vertical. For example, the display screen 206S may have a rectangular shape with its longitudinal direction being horizontal. In addition, the standard display unit 206 receives input operations to the input unit 206I and outputs information indicating the operation content to the standard display control unit 2012.

[0034] The extended display unit 207 is, for example, a touch panel. The extended display unit 207 is an input / output device that integrally comprises an input unit 207I that accepts input operations by touching the display screen 207S with a fingertip or an input pen, and an output device that displays an image on the display screen 207S. The extended display unit 207 is controlled by the extended display control unit 2015, which will be described later, and displays information related to the work machine 100 on the display screen 207S. The information related to the work machine 100 displayed on the display screen 207S is, for example, information related to the automatic operation of the work machine 100 or information-based construction. In this embodiment, the vertical and horizontal directions of the display screen 207S are as shown in Figure 2. Also, in this embodiment, the display screen 207S has a rectangular shape with its longitudinal direction being vertical. For example, the display screen 207S may have a rectangular shape with its longitudinal direction being horizontal. Furthermore, the extended display unit 207 receives input operations to the input unit 207I and outputs information indicating the operation content to the extended display control unit 2015.

[0035] (Configuration of control system 200) Figure 5 is a schematic block diagram showing the hardware configuration of the control system 200 of the work machine 100 according to an embodiment of the present disclosure. The control system 200 includes a controller 201. The controller 201 includes an input / output unit 2011, a standard display control unit 2012, a work machine control unit 2013, a storage unit 2014, and an extended display control unit 2015. The control system 200 also includes a plurality of cameras 126, a standard display unit 206, an extended display unit 207, a plurality of push-button switches BSW, switches LL-SW, a plurality of other sensors 208, a plurality of actuators 209, and the like.

[0036] The controller 201 can be configured using a computer such as a microcontroller or CPU (Central Processing Unit), and hardware such as peripheral circuits and peripheral devices of the computer. Alternatively, the controller 201 may be configured using a custom LSI (Large Scale Integrated Circuit) such as a PLD (Programmable Logic Device). Examples of PLDs include PAL (Programmable Array Logic), GAL (Generic Array Logic), CPLD (Complex Programmable Logic Device), and FPGA (Field Programmable Gate Array). Furthermore, some or all of the functions realized by the processor may be realized by the integrated circuit. The controller 201 comprises an input / output unit 2011, a standard display control unit 2012, a work machine control unit 2013, a storage unit 2014, and an extended display control unit 2015 as a functional block composed of a combination of hardware such as a computer and software such as a program executed by the computer. The controller 201 may be configured as a single controller, or it may be configured as multiple controllers connected and cooperating via a predetermined communication line, for example. As mentioned above, the extended display unit 207 is not required. Alternatively, the combination KD1 of the extended display unit 207 and the extended display control unit 2015 is not required.

[0037] The input / output unit 2011 inputs and outputs predetermined signals (input or output or input and output) to and from multiple cameras 126, multiple push-button switches BSW, switches LL-SW, multiple other sensors 208, and multiple actuators 209.

[0038] The memory unit 2014 has the function of storing and managing information (referred to as setting information) that represents the assignment of functions to the push-button switches BSW. In addition, if the operator changes the settings such as the assignment of functions to the push-button switches BSW, it retains information indicating the changed function assignments to the push-button switches BSW. For example, when an inquiry is received from the work machine control unit 2013, it provides setting information indicating the function assignments to the push-button switches BSW that are currently set for the logged-on operator. The setting information includes information indicating each function assigned to the multiple push-button switches BSW provided on the left operating lever 143LO and the right operating lever 143RO.

[0039] The work machine control unit 2013 acquires various data related to the hydraulic equipment that controls the operation of the work machine 130 using multiple sensors 208, and outputs multiple control signals to multiple actuators 209 related to the work machine 130 to control the hydraulic equipment according to the operation of the operating device 143. The work machine control unit 2013 also transmits information related to the operation of the work machine 100 to the standard display control unit 2012, the extended display control unit 2015, etc. The work machine control unit 2013 also transmits information related to the extended functions to the extended display control unit 2015.

[0040] Furthermore, the multiple sensors 208 include multiple sensors for detecting the operating status of the operating device 143, including push-button switches BSW and LL-SW; a sensor for detecting the hydraulic oil temperature; a sensor for detecting the hydraulic pressure; a sensor for detecting the attitude of the work machine 130; multiple GNSS (Global Navigation Satellite System) sensors; a LiDAR (Light Detection and Ranging) sensor; and the like. The multiple actuators 209 include a hydraulic pump 122; a control valve 123; a boom cylinder 131C; an arm cylinder 132C; a bucket cylinder 133C; a travel motor 112; a slewing motor 124; and the like.

[0041] The standard display control unit 2012 controls the image display on the display screen 206S of the standard display unit 206 and notifies the work machine control unit 2013 of the occurrence of a touch operation on the input unit 206I of the standard display unit 206. The standard display control unit 2012 also acquires image information etc. from the camera 126 via the input / output unit 2011 and acquires information representing the operating status of the work machine 100, setting status such as the operating mode of the work machine 100, and setting information etc. from the work machine control unit 2013. Furthermore, the standard display control unit 2012 generates a display image to be displayed on the display screen 206S based on the acquired information, input operations on the input unit 206I etc., based on a predetermined number of display modes. In this embodiment, "display screen" (display screen 206S and display screen 207S) means the surface on which the image is displayed. The standard display control unit 2012 also transitions the display image based on the acquired information, signals input from the standard display unit 206 etc. The standard display control unit 2012 controls the standard display unit 206 to display the generated image on the display screen 206S. The standard display control unit 2012 and the standard display unit 206 may be configured as an integrated unit or as separate units. In the examples shown in Figures 2 and 3, they are configured as an integrated unit and are further integrated with the right console box 143RC.

[0042] The extended display control unit 2015 controls the image display on the display screen 207S of the extended display unit 207 and notifies the work machine control unit 2013 of the occurrence of a touch operation on the input unit 207I of the extended display unit 207. The extended display control unit 2015 acquires from the work machine control unit 2013 the operating status of the work machine 100, the setting status of the operating mode of the work machine 100, setting information, and information related to the extended function. The extended display control unit 2015 also generates a display image to be displayed on the display screen 207S based on the acquired information and signals input from the extended display unit 207, based on a predetermined set of display modes. The extended display control unit 2015 also transitions the display image based on the acquired information and signals input from the extended display unit 207. The extended display control unit 2015 controls the extended display unit 207 to display the generated image on the display screen 207S. The extended display control unit 2015 and the extended display unit 207 may be configured as an integrated unit or as separate units. In the examples shown in Figures 2 and 3, the components are integrally formed and attached to the pillars (window pillars) of the driver's cab 140.

[0043] (Example of setting up a push-button switch BSW using the standard display unit 206) Next, an example of the operation of the control system 200 when setting or changing the function assignment to the push-button switch BSW using the standard display unit 206 will be described with reference to Figures 6 to 18. This example of operation is for cases where the control system 200 does not have an extended display unit 207. However, the following example of operation also includes some examples of operation when the control system 200 is equipped with an extended display unit 207.

[0044] Figures 6, 11, and 15 show a series of transitions in the display images on the display screen 206S of the standard display unit 206, divided into three diagrams. Figure 6 shows the transition from display image D1 to display image D3, up to the point where image D33 is pressed. Figure 11 shows the transition of display images when a function is selected on display image D6 (selection image) which is displayed after image D33 is pressed on display image D3. Figure 15 shows the transition of display images when the function selected on display image D6 is reflected in the system. Figures 7 to 10, 12 to 14, and 16 to 18 show enlarged views of display images D1 to D4, D6, D8, D9, and D15 to D17 on the display screen 206S included in Figures 6, 11, and 15.

[0045] The transition shown in Figure 6 begins with display image D1 (Figure 7). Display image D1 shown in Figure 7 is the image (home screen) that is displayed by default on the display screen 206S when the work machine 100 is operational. However, the home screen is not limited to display image D5, but can be any display screen. Display image D1 includes an overhead image D1-1 and a single-camera image D1-2 generated based on images captured by multiple cameras 126. Display image D1 also includes an image D1-7 representing a menu button.

[0046] As shown in Figure 6, when the lock lever 143LL is in the locked state (LL lock) and the image D1-7 representing the menu button is pressed (tapped) in the display image D1 (home screen) (Figure 7), the display image D2 (Figure 8) is displayed. As shown in Figure 8, the display image D2 includes image D2-1 for switching the assignment of the lever switch (push button switch BSW) and image D2-2 representing the button (hereinafter referred to as the home button) for returning to the display image D1 (home screen).

[0047] As shown in Figure 6, when image D2-1 is pressed in display image D2, display image D3 (Figure 9) is displayed if condition A is not met, and display image D4 (Figure 10) is displayed if condition A is met. Condition A is that the control system 200 is equipped with an extended display unit 207 (or a combination of the extended display unit 207 and the extended display control unit 2015 KD1). Condition A can be changed arbitrarily. In the display images, the extended display unit 207 (or a combination of the extended display unit 207 and the extended display control unit 2015 KD1) is referred to as the extended monitor. As shown in Figure 9, display image D3 includes image D31, which represents an explanatory text for canceling the execution state of lever switch assignment switching; image D33, which represents a "Yes" button for starting the setting; image D32, which represents a "No" button for not starting the setting; and image D2-2, which represents the home button. Furthermore, as shown in Figure 10, the displayed image D4 includes image D41, which represents a message instructing that lever switch assignment switching should be performed on the extended monitor; image D42, which represents a button to return to the previous displayed image; and image D2-2, which represents the home button.

[0048] As shown in Figure 6, if display image D2 is displayed and no operation continues for 30 seconds, display image D1 will be displayed. If display image D3 is displayed and image D32 is pressed, or if no operation continues for 30 seconds, display image D2 will be displayed. If display image D3 is displayed and condition A is met, display image D4 will be displayed. If display image D3 is displayed and image D33 is pressed, display image D6 (Figures 11 and 12) will be displayed. If display image D4 is displayed and condition A is not met, display image D3 will be displayed. If display image D4 is displayed and image D42 is pressed, or if no operation continues for 30 seconds, display image D2 will be displayed. Note that the duration of the no-operation state may be set arbitrarily, for example.

[0049] As shown in Figure 6, when display image D2, D3, or D4 is displayed (display state DS1), if image D2-2 is pressed or the lock lever 143LL is released, display image D1 is displayed.

[0050] Next, if image D33 is pressed while display image D3 is displayed, display image D6 (Figure 12) will be displayed as shown in Figure 11. As shown in Figure 12, display image D6 is the selection image when it is possible to register three different settings (No. 1 to No. 3) for the push button switch BSW. Display image D6 includes image D61 which of No. 1 to No. 3 is selected, image D62 which represents a list of the settings for each push button switch BSW of the left operating lever 143LO (a list of each function assigned to push button switches BSWL1 to 5 from top to bottom) (hereinafter also referred to as the function list), image D63 which represents a list of the settings for each push button switch BSW of the right operating lever 143RO (a list of each function assigned to push button switches BSWR1 to 5 from top to bottom), image D64 which represents a button to reset the registered settings to their initial values, and image D65 which represents a button to confirm the selected assignment settings. Furthermore, image D61 can be selectively pressed for each "No." from No.1 to No.3, and images D62 and D63 can be selectively pressed for each push button switch BSW.

[0051] If, while display image D6 is displayed, the image corresponding to the push button switch BSWL2 in image D62 ("2" No setting) is pressed ("Touch function list"), then display image D8 (Figure 13) will be displayed as shown in Figure 11. In this case, since no function is set for the push button switch BSWL2 ("No setting"), and the image corresponding to the push button switch BSWL2 is pressed, the transition shown in Figure 11 is equivalent to touching the function list, and display image D8 is displayed. As shown in Figure 13, display image D8 includes image D81 representing the currently selected function for the push button switch BSWL2, image D82 representing a list of classifications related to assignable functions, and image D83 representing a button to return to the previous display image.

[0052] As shown in Figure 11, when the image representing "General" in image D82 is pressed (the list is touched) in display image D8 (Figure 13), display image D9 (Figure 14) is displayed. As shown in Figure 14, display image D9 includes image D91 representing the selected function (in this case, "No setting") for the push button switch BSW (in this case, push button switch BSWL2) to be configured, image D92 representing a list of functions classified as "General" among the multiple functions that can be assigned, and image D93 representing a button to return to the previous display image.

[0053] As shown in Figure 11, when the desired function is pressed (touched) from the list image D92 in the display image D9 (Figure 14), the display image D6 (Figure 12) is displayed. However, in this example, the "No setting" of the push button switch BSWL2 (left lever "2") in the display image D6 shown in Figure 12 will be changed to one of several functions shown in Figure 14, such as "Camera image switching," "Front window wiper," or "Window washer."

[0054] Furthermore, as shown in Figure 15, when display image D6 (identical to display image D6 in Figure 11) (Figure 12) is displayed, and image D65, which represents a button for confirming the assignment settings for assigning the selected function, is pressed, display image D15 (Figure 16) is displayed.

[0055] As shown in Figure 16, display image D15 includes image D151, which represents text information indicating that each push-button switch BSW should be set, and image D152, which represents guidance regarding push-button switch BSWL1 for reflecting the settings. Image D152 includes image D153, which represents push-button switch BSWL1 (left lever switch 1), and image D154, which represents text information. Display image D15 also displays the setting information recognized by the work machine control unit 2013.

[0056] As shown in Figure 15, when the push-button switch BSWL1 is pressed while display image D15 is displayed, display image D16 (Figure 17) is displayed. When the push-button switch BSWL1 is pressed, the work machine control unit 2013 recognizes that the push-button switch BSWL1 has been pressed. Upon recognizing that the push-button switch BSWL1 has been pressed, the work machine control unit 2013 notifies the standard display control unit 2012 of this fact. In response to this notification, the standard display control unit 2012 transitions the display image from display image D15 to display image D16.

[0057] As shown in Figure 17, the display image D16 includes image D161, which indicates that the settings have been applied, image D2-2, which represents the home button, and image D162, which represents the "Confirm (Yes)" button. As shown in Figure 15, if image D162 is pressed while display image D16 is displayed, or if 3 seconds have elapsed since display image D16 was displayed, display image D2 (Figure 8) is displayed. The elapsed time can be set arbitrarily, for example. Also, if image D2-2 is pressed or the lock lever 143LL becomes unlocked (LL released) while display image D16 or display image D2 is displayed (display state DS3), display image D1 is displayed. Also, if the lock lever 143LL becomes unlocked (LL released) while display image D6 or D15 is displayed (display state DS2), display image D17 (Figure 18) is displayed. Although not shown in Figure 11, as shown in Figure 11, when the lock lever 143LL is released (LL released) while displaying images D6, D8, or D9, display image D17 (Figure 18) is displayed.

[0058] As shown in Figure 18, display image D17 is a display image in which the popup window D171 is superimposed on display image D1 (Figure 7). The popup window D171 includes image D172, which indicates that the setting change has been canceled, and image D173, which is used to close the popup window D171. As shown in Figure 15, when display image D17 is displayed, display image D1 is displayed when image D173 is pressed or when 10 seconds have elapsed since display image D17 was displayed. Note that the elapsed time can be set arbitrarily, for example.

[0059] As described above, the standard display control unit 2012 changes the selection of the function assigned to the push button switch BSW by transitioning the display image displayed on the display screen 206S, as shown in Figures 6, 11, and 15. The setting is reflected after the work machine control unit 2013 detects that the push button switch BSWL1 has been pressed. Display images D6, D8, D9, and D15 are examples of the selection images related to this disclosure.

[0060] (Example of setting up the push-button switch BSW using the extended display unit 207) Next, an example of setting the push-button switch BSW using the extended display unit 207 will be described with reference to Figures 19 to 30. Figures 19 and 26 show a series of transitions in the display images on the display screen 207S of the extended display unit 207, divided into two diagrams. Figure 19 shows the transition from display image D21 to display image D25. Figure 26 shows the transition of display images when selecting a function from display image D25 to display image D26, etc. Figures 20 to 25 and Figures 27 to 30 show enlarged views of display images D21 to D29 on the display screen 207S included in Figures 19 and 26.

[0061] The transition shown in Figure 19 begins with either display image D21 (Figure 20) or display image D22 (Figure 21). Display image D21 (Figure 20) is an example of a display image shown on the display screen 207S when the work machine 100 is operational. Display image D21 displays multiple pieces of information related to the work machine 100. Display image D21 is also a settings screen for configuring various functions, and includes, for example, an image (area image) D211 representing a list of functions assigned to the lever switch (push button switch BSW) and an image (area image) for starting operations to check or change the functions assigned to the push button switch BSW, and an image D212 representing a button to display display image D22. Display image D22 (Figure 21) is the image (home screen) that is displayed on the display screen 207S by default when the work machine 100 is operational. However, the home screen is not limited to display image D22; any display screen may be used. Display image D22 includes image D221 representing a three-dimensional model showing the work target of the work machine 100, image D222 representing a lateral model, image D223 representing a planar model, image D224 representing a menu button for displaying the settings screen (display image D21), and image D225 representing a button for displaying the screen for making various settings (display image D23 in Figure 22), etc.

[0062] As shown in Figure 19, when image D212 is pressed in display image D21 (Figure 20), display image D22 (Figure 21) is displayed, and when image D224 is pressed in display image D22 (Figure 21), display image D21 (Figure 20) is displayed. Also, when image D211 is pressed (area tapped) in display image D21 (Figure 20), display image D24a (Figure 23) is displayed. Also, when image D225 is pressed in display image D22 (Figure 21), display image D23 (Figure 22) is displayed. Display image D23 shown in Figure 22 is a screen for starting various setting operations, and includes image D231 for starting the lever switch assignment switching operation, image D232 representing a button to return to the previous display image, and image D233 representing the home button. When image D231 is pressed in display image D23 (Figure 22), display image D24b (Figure 24) is displayed. In the displayed image D23 (Figure 22), if image D232 or image 233 is pressed, displayed image D22 (Figure 21) will be displayed.

[0063] The display images D24a shown in Figure 23 and D24b shown in Figure 24 (collectively referred to as display image D24) include image D240, which represents the list of functions currently assigned to the lever switch (push button switch BSW), and image D241, which represents a button to start the process of changing the selected function. Both display image D24a shown in Figure 23 and display image D24b shown in Figure 24 are images (intermediate images in the transition to the selection image) for selecting each function to be assigned to the push button switch BSW from multiple functions, but they differ in that display image D24a is a display image that is displayed with display image D21 (settings screen) as the source image, while display image D24b is a display image that is displayed via display image D23 with display image D22 (home screen) as the source image. Therefore, display image D24a (Figure 23) includes image D224, which represents a menu button for displaying the settings screen (display image D21), while display image D24b (Figure 24) includes image D233, which represents a home button for displaying the home screen (display image D22). In this case, the icon (menu button or home button) for returning from display image D24 to the source image (display image D21 or display image D22) will change depending on which source image the user transitioned from. Note that image D242, which represents a button to return to the previous display image included in display image D24a, and image D244, which represents a button to return to the previous display image included in display image D24b, are the same image (icon), but the destination display image is different. In this embodiment, an icon refers to an image that represents an illustration or graphic that clearly symbolizes instructions, commands, etc., given to a computer.

[0064] As shown in Figure 19, when image D242 or image D224 is pressed in display image D24a (Figure 23), display image D21 (Figure 20) is displayed, and when image D241 is pressed, display image D25 (Figure 25) is displayed. Also, as shown in Figure 19, when image D244 is pressed in display image D24b (Figure 24), display image D23 (Figure 22) is displayed, and when image D233 is pressed, display image D22 (Figure 21) is displayed. Furthermore, when image D241 is pressed in display image D24b (Figure 24), a display image that is almost identical to display image D25 (Figure 25) is displayed (image D224 of display image D25 shown in Figure 25 is deleted, and a display image including image D233 is displayed in the same way as display image D24b shown in Figure 24). Note that display images D24a, D24b, and D25 are images in the transition to the selected image in this disclosure.

[0065] The display image D25 shown in Figure 25 includes image D250, which represents explanatory information indicating that the lock lever 143LL must be locked (LL lock) when setting the push button switch BSW; image D251, which represents a button to instruct the user to perform the setting operation; image D252, which represents a button to return to the previous display image; and image D224, which represents a menu button to display the setting screen (display image D21). As shown in Figure 19, when image D252 is pressed in display image D25 (Figure 25), display image D24a (Figure 23) is displayed. Also, as shown in Figure 19, when image D224 is pressed in display image D25 (Figure 25), display image D21 (Figure 20) is displayed. Furthermore, as shown in Figure 26, when image D251 is pressed with the lock lever 143LL in the locked state (LL lock), display image D26 (Figure 27) is displayed.

[0066] The display image D26 shown in Figure 27 is a display image (selected image) that corresponds to the display image D6 (selected image) (Figure 12) displayed on the display screen 206S of the standard display unit 206. Display image D26 includes image D261, which represents a function list that is a list of each function assigned to the push button switch BSW, and image D262, which represents a button for confirming the setting of the selected assignment. As shown in Figure 26, when any part of image D261 that corresponds to the push button switch BSW in display image D26 is pressed, display image D27 (Figure 28) is displayed. Display image D27 is also a selected image.

[0067] The display image D27 shown in Figure 28 includes image D271, which represents a hierarchical list of assignable functions by category; image D272, which represents a button for confirming the selected function; and image D273, which represents a button for returning to the previous display image. As shown in Figure 26, after one of the functions represented by image D271 in display image D27 (Figure 28) is selected (pressed), if image D272 is pressed, display image D26 (Figure 27) is displayed, which includes image D261 showing the selected function in display image D27 as the new assignment. Also, if image D273 is pressed in display image D27, display image D26 (Figure 27) is displayed. However, when display image D26 is displayed by pressing display image D273, the content of display image D26 does not change between before display image D27 is displayed and when display image D26 is displayed again.

[0068] Furthermore, as shown in Figure 26, when image D262 is pressed in display image D26 (Figure 27), display image D28 (Figure 29) is displayed. Display image D28 shown in Figure 29 includes image D281, which indicates that the settings will be reflected when the push button switch BSWL1 is pressed. As shown in Figure 26, when the push button switch BSWL1 is pressed while display image D28 is displayed, display image D29 (Figure 30) is displayed. When the push button switch BSWL1 is pressed, the work machine control unit 2013 recognizes that the push button switch BSWL1 has been pressed. Upon recognizing that the push button switch BSWL1 has been pressed, the work machine control unit 2013 notifies the extended display control unit 2015 of this fact. In response to this notification, the extended display control unit 2015 transitions the display image from display image D28 to display image D29.

[0069] The display image D29 shown in Figure 30 includes image D291, which indicates that the settings have been applied, and image D292, which represents a button indicating that the contents of display image D29 have been confirmed. As shown in Figure 26, when image D292 is pressed in display image D29, the original display image D21 (Figure 20) or display image D22 (Figure 21) is displayed. Also, when the lock lever 143LL becomes unlocked (LL released) while display image D26, display image D27, display image D28, or display image D29 is displayed (display state DS21), the original display image D21 (Figure 20) or display image D22 (Figure 21) is displayed.

[0070] The extended display control unit 2015 changes the function assigned to the push button switch BSW by transitioning the display image shown on the display screen 207S as described above. The setting is applied after the work machine control unit 2013 detects that the push button switch BSWL1 has been pressed.

[0071] (Effects / Actions) As described above, the control system 200 of this embodiment is a control system that controls the operation of the work machine 100 in accordance with the operation of the left operating lever 143LO and the right operating lever 143RO, which have a plurality of push-button switches BSW (operators). The control system 200 includes at least the standard display unit 206 (first display device) and the extended display unit 207 (second display device), which display information related to the work machine 100. The standard display unit 206 (first display device) and the extended display unit 207 (second display device) can display selection images (display image D6, etc. or display image D26, etc.), which are images for selecting each function to be assigned to one or more push-button switches BSW (operators) from a plurality of functions. Furthermore, if the control system 200 includes both the standard display unit 206 (first display device) and the extended display unit 207 (second display device), the standard display unit 206 (first display device) does not display selection images (display image D6, etc.). This configuration prevents, for example, the selection image from being displayed simultaneously on the standard display unit 206 and the extended display unit 207, and allows for the appropriate display of images for selecting the function to be assigned to the buttons on the operating lever. Furthermore, even if the extended display unit 207 (second display device) is added later to a model that only has the standard display unit 206 (first display device), the extended function can still be assigned to the buttons on the operating lever.

[0072] Furthermore, in this embodiment, the assignable functions include one or more extended functions that can only be used when the extended display unit 207 (second display device) is provided. Also, in this embodiment, the types of functions that can be selected from the selected images displayed by the standard display unit 206 (first display device) are different from the types of functions that can be selected from the selected images displayed by the extended display unit 207 (second display device). With these configurations, the standard display unit 206 (first display device) does not need to support all types of functions that can be selected from the selected images displayed by the extended display unit 207 (second display device).

[0073] Furthermore, it is desirable that the extended functions be able to be added to the work machine 100, for example, after it has left the factory. The extended functions can be added, for example, by using communication via a wide-area communication network.

[0074] Furthermore, in this embodiment, the selected image (display image D26) can be reached by transitioning through multiple different images (display images D21 and D22) as the source image. The icons (images D224 and D233) included in the images (display images D24a, D24b, and D25) that allow the user to return to the source image change depending on which source image the transition originated from. This configuration makes it easy to understand which image was used as the source image to reach the selected image.
