Abstract
Description
[Technical Field]
[0001] The present invention relates to an operating system that can be used to operate self-propelled construction machinery, such as a self-propelled soil compactor. [Background technology]
[0002] Self-propelled construction machinery has many functions that operators can selectively enable or disable, or change the intensity of; therefore, it is necessary to provide an operating system that allows for the selection, activation, or deactivation of various functions. For example, a so-called rotary / push-type actuator can be used, for instance, where selection is made by rotation and confirmation of the selection, or activation or deactivation of the selected function, is performed by pressing. In other known operating systems, touchscreens are used as an alternative or additional method, allowing for the selection, activation, and deactivation of functions by touching the touch sensor screen. [Overview of the project] [Problems that the invention aims to solve]
[0003] The object of the present invention is to provide an operating system, particularly an operating system for self-propelled construction machinery, that helps to avoid the occurrence of errors due to its ease of operation. [Means for solving the problem]
[0004] According to the present invention, this problem is solved by an operating system, particularly an operating system for self-propelled construction machinery, and said operating system is - A first operating mechanism that operates in a first type of operation to select one function from among multiple selectable functions, and in a second type of operation to confirm the selection of a function from among multiple selectable functions, wherein a first lighting unit for illuminating the first operating mechanism is provided, - A screen for displaying a function that can be selected and / or selected using a first operating mechanism, It includes, At least one of several selectable functions, preferably each function, is assigned a function color coding, and the first lighting unit is configured to illuminate the first operating mechanism with a color corresponding to the function color coding of the selected function after the function has been selected and / or confirmed using the first operating mechanism.
[0005] In the operating system according to the present invention, there is an interaction between the display of various selectable functions on the screen and the color-coded highlighting of the first operating mechanism. When an operator selects one of the functions displayed on the screen with various function color codes by operating the first operating mechanism in a corresponding manner, according to the present invention, the operator can recognize which function has been selected by observing only the first operating mechanism and not the screen, based on the agreement between the color illuminating the first operating mechanism and the function color code assigned to the selected function. In particular, when various functions are interconnected, the illumination color of the first operating mechanism may be set to correspond to the function color code of the currently selected function. Alternatively, the first illumination unit may be configured to illuminate the first operating mechanism with a color corresponding to the function color code assigned to the selected function only when the selection is confirmed by appropriately operating the first operating mechanism.
[0006] In a configuration where operation is particularly easy and functionally reliable due to the clear distinction between various types of operation, the first operating mechanism rotates around the axis of rotation to operate in the first type of operation and displaces in the direction of the axis of rotation to operate in the second type of operation. In this configuration, the first operating mechanism is configured as a rotary / push-type actuator.
[0007] In particular, when multiple different function modes are selectable and assigned to respective selectable functions, for example, to execute the selected function in various intensity levels, after the screen selects one of the multiple functions, the screen is configured to display the multiple selectable function modes assigned to the selected function. The first operation mechanism may be set to operate in a first operation type to select one of the multiple selectable function modes and to operate in a second operation type to confirm the selection of one of the multiple selectable function modes.
[0008] Also, when there are multiple selectable function modes, at least one of the multiple selectable functions, preferably each function, is assigned a function mode color coding for at least one of the multiple selectable function modes assigned to the function, preferably each function mode, so that the operator can more easily identify the function mode by color highlighting. The first lighting unit may be configured to illuminate the first operation mechanism with a color corresponding to the function mode color coding of the selected function mode after the selection or / and confirmation of the selection of the function mode using the first operation mechanism.
[0009] To avoid the stimulation induced by an excessive number of different lighting colors or display colors and the resulting misoperations, it is proposed to assign the same function mode color coding to at least two, preferably all, of the function modes assigned to at least one of the multiple selectable functions, preferably each function.
[0010] When the function mode color coding matches the function color coding of the assigned function for at least one of the multiple selectable functions, preferably each function, and for at least one of the function modes assigned to the function, preferably each function mode, the risk of misoperations induced by an excessive number of different colors is further reduced.
[0011] In a particularly preferred configuration, the screen may be a touchscreen, and at least one of a plurality of selectable functions, preferably each function, can be selected by touching the screen in addition to being selected by a first operating mechanism, and / or, the selection of at least one of a plurality of selectable functions, preferably each function, can be confirmed by touching the screen.
[0012] Regardless of the method of selecting a function, it is proposed that the first lighting unit be configured to illuminate the first operating mechanism in a color corresponding to the function color coding of the selected function after the operator has selected one of several selectable functions by touching a screen, and / or after the selection has been confirmed, so that the operator can easily recognize the selection or confirmation.
[0013] If multiple function modes are selectable by assigning to one or more selectable functions, it may be further configured so that at least one of the multiple selectable function modes, preferably each function mode, can be selected by touching the screen, and / or so that the selection of at least one of the multiple selectable function modes, preferably each function mode, can be confirmed by touching the screen.
[0014] In this case as well, with respect to clear highlighting of the selected function mode, it is advantageous that the first lighting unit is configured to illuminate the first operating mechanism in a color corresponding to the function mode color coding of the selected function mode after selecting one of several selectable function modes by touching the screen, or / or after confirming the selection.
[0015] The operating system according to the present invention may further include at least one second operating mechanism, such as an operating button, which can enable and / or disable the selected function.
[0016] In this case, to enhance operational safety, with respect to a function whose selection has been confirmed, the function mode assigned to that function and whose selection has been confirmed can be enabled and / or disabled by at least one second operating mechanism.
[0017] To avoid erroneous operation, a second operating mechanism may be provided for at least some of the multiple selectable functions, preferably assigned to each function.
[0018] In order to obtain a color interaction between at least one second operating mechanism and a screen or a first operating mechanism, it is proposed that a second lighting unit be provided, assigned to at least one second operating mechanism, and that the second lighting unit be configured to illuminate at least one second operating mechanism in a color corresponding to the functional color coding of a function whose selection is confirmed and which is enabled or / or disabled by at least one second operating mechanism.
[0019] To allow the operator to recognize that no function has been selected, the second lighting unit may be configured not to illuminate at least one second operating mechanism, or to illuminate it in an intermediate color, when no function has been selected and / or confirmed.
[0020] The first lighting unit may also be configured not to illuminate the first operating mechanism, or to illuminate it in an intermediate color, when no function is selected and / or confirmed.
[0021] To facilitate operation, at least one second operating mechanism can be configured as a push button.
[0022] The present invention further relates to self-propelled construction machinery, particularly earthwork machinery such as a soil compactor, which includes an operating system according to the present invention.
[0023] The present invention will be described in detail below with reference to the accompanying drawings. The drawings are shown below. [Brief explanation of the drawing]
[0024] [Figure 1] This is a side view of a self-propelled construction machine configured as a soil compactor. [Figure 2] For example, Figure 1 is a side view of an operating mechanism configured as a rotary / pushing device for the operating system of a construction machine. [Figure 3] This diagram shows the screen of an operating system along with multiple functions displayed on the screen, and is a diagram showing the screen with multiple function modes assigned to a selected function. [Figure 4] This diagram shows a screen corresponding to Figure 3, where multiple selectable function modes are displayed, each assigned to a different selected function. [Figure 5] This figure shows a control panel equipped with multiple operating mechanisms configured as push buttons. [Figure 6a] This figure shows an alternative embodiment of a control panel equipped with push buttons that constitute an operating mechanism. [Figure 6b] This figure shows an alternative embodiment of a control panel equipped with push buttons that constitute an operating mechanism. [Figure 7] This figure shows a portion of the armrest where the system area of the operating system is incorporated. [Modes for carrying out the invention]
[0025] Figure 1 shows a side view of a self-propelled construction machine 10 configured as a soil compactor. The self-propelled construction machine 10 includes a rear section 12 and a front section 14, which are continuous in the longitudinal direction L, which mainly corresponds to the direction of movement. The rear section 12 is equipped with wheels 16 driven by a drive unit located at the rear of the vehicle to move the construction machine 10 on the ground B, and a driver's cab 18. An operator 22 can sit in a seat 20 located in the driver's cab 18 to operate the construction machine 10. A soil compactor roller 24 is rotatably mounted on the front section 14, so that when the machine moves on the ground B, the ground B is compacted by the load of the soil compactor roller 24.
[0026] The driver's cab 18 is equipped with an operating system 26, which is described in detail below, and the operator 22 can use the operating system 26 to operate the construction machine 10.
[0027] First, it should be noted that the construction machine 10 shown in Figure 1, which includes a front vehicle section 14 and a rear vehicle section 12, is merely one example of the various construction machines that can be operated by the operating system 26 described in detail below. For example, a soil compactor with a different structure can also constitute such a construction machine 10. Such a soil compactor may be a pivot-steering type soil compactor, for example, having two steering pivots on the machine frame, each supporting an earthwork roller, and the steering pivots being rotatable relative to the machine frame for steering the soil compactor. Other types of construction machines, such as wheel loaders, power shovels, and road milling machines, can also be operated by an operator 22 using such an operating system 26.
[0028] Figure 2 shows a first operating mechanism 28, configured as a rotary / push-type actuator, as a main component of the operating system 26. The first operating mechanism 28 includes an actuator 32 that is supported on a base 30 so as to be rotatable about a rotation axis D and displaceable on the base 30 in the direction of the rotation axis D. As will be described in detail below, the actuator 32 can rotate about the rotation axis D in the first type of operation and move toward the base 30 in the direction of arrow P in the second type of operation.
[0029] The actuator 32 may be formed transparently in the outer peripheral region 34 that surrounds the rotation axis D in an annular shape, so that the light generated by the first lighting unit 36 provided on the base 30 can pass through the outer peripheral region 34 and be visible, or the actuator 32 can be seen by the color of the light emitted by the first lighting unit 36. The first lighting unit 36 may also be formed to surround the rotation axis D in an annular shape, and may be configured as a so-called RGB-LED (red, yellow, and blue LED) to generate light of various colors.
[0030] As shown in Figure 7, the first operating mechanism 28 can be incorporated into an armrest 38 located next to the seat 20 of the driver's cab 18. The first operating mechanism 28 or its actuator 32 may be equipped with a handrest 40, which allows the operator 22 to operate the actuator 32 in an ergonomically advantageous manner while resting their hand on the handrest 40.
[0031] The operating system 26 includes, as a further component, a screen 42, which is shown in principle in Figure 3. The screen 42 may be located, for example, in the instrument area 44 positioned in front of the seat 20, within the field of view of the operator 22, but may also be basically integrated into the armrest 38. The screen 42 is advantageously configured as a touchscreen and has a touch sensor surface 46, so that by touching the touch sensor surface 46, the operator 22 can input operating commands to the operating system 26 via the screen 42. With the screen 42 configured as a touchscreen and the first operating mechanism 28 configured as a rotary / push-button actuator, the operating system 26 incorporates two system areas through which the operator 22 can input operating commands.
[0032] For example, the armrest 38 incorporates a plurality of second operating mechanisms 48 configured as push buttons. For this purpose, the armrest 38 may be provided with a control panel 51 that groups these second operating mechanisms 48 together. The control panel 51 is located next to the first operating mechanism 28 and can be operated even when the operator has their hands on the handrest 40. The control panel 51 and the second operating mechanisms 48 provided on the control panel 51 constitute a third system area of the operating system 26, and the operator 22 can input operating commands to the operating system 26 through the third system area in the manner described later.
[0033] Figure 3 shows that the screen 42 may display a number of functions 50 that can be selected by the operator 22, for example, in the form of tiles or other display symbols. In the illustrated example, these are four functions 501, 502, 503, and 504, each represented by a tile. Examples of such functions include, for example, a compaction method of vibration and / or oscillation, spraying water and / or additives onto the compaction roller 24, track offset (commonly also called "dogwalk") of the compaction roller on a pivot-steering soil compactor, a lighting function, operation of a crushed stone spreader, operation of an edge press device, operation of heating and air conditioning equipment, and operation of an audio system. The operator 22 can select one of the functions 501, 502, 503, and 504 displayed on the screen 42 by rotating the actuator 32.
[0034] Even when the operator is observing the ground B in front of the construction machine 10 with greater focus, each function 501, 502, 503, and 504 displayed on the screen 42 is assigned a function color coding, for example, by a colored border area 52 surrounding each display tile, so that various functions can be easily recognized. In this case, for example, when a function is selected by rotating the actuator 32, each function 501, 502, 503, and 504 may be set to be displayed with its respective function color coding. In the embodiment of Figure 3, all functions that have not been selected at this point, i.e., functions 501, 503, and 504, are displayed in an intermediate color, for example, white. In other words, within the scope of the present invention, such an intermediate color is a color that has not been assigned to any function as a function color coding.
[0035] When one of functions 501, 502, 503, or 504 is selected and displayed on the screen 42 with the correspondingly assigned function color coding, the first lighting unit 36 operates to produce light of the same color, and thus illuminates the actuator 32 or the first operating mechanism 28 in the color corresponding to the selected function, in this case function 502's function color coding. Thus, the operator 22 is given a consistent visual impression in two system areas, the screen 42 on the one hand and the first operating mechanism 28 on the other, so that the operator 22 can recognize which function has been selected with just a glance at the screen 42 or the first operating mechanism 28. It should be taken into consideration that an operator 22 skilled in operating the construction machine 10 understands which function color coding is assigned to which function. Being able to recognize the selected function on both the screen 42 and the first operating mechanism 28 is particularly advantageous, for example, when the construction machine 10 is operated in darkness.
[0036] After selecting one of the displayed selectable functions 501, 502, 503, and 504, namely function 502 in the example shown in Figure 3, the operator 22 confirms this selection by pressing the actuator 32 and displacing it toward the base 30 in the direction of arrow P.
[0037] After confirming the selected function (function 502 in the example of Figure 3), the screen 42 displays the function modes 54 that can be assigned to or selected for the selected function 502, or, if a function mode 54 is already displayed, it is visually highlighted, for example. In the state shown in Figure 3, function 502 has three function modes 54. 2a , 54 2b , 54 2c There exists. For example, if function 502 represents spraying onto the compaction roller 24, then function mode 54 2a , 54 2b , 54 2c This can reflect the intensity of the spraying.
[0038] The operating device 32 of the first operating mechanism 28 is operated in a first operation type, that is, rotated around the rotation axis D, so as to select one of the function modes 54 assigned to the function 502. After the selection is made, the selected function mode can be confirmed by operating in a second operation type, that is, by pressing the operating device 32. 2a , 54 2b , 54 2c One of them can be selected. After the selection is made, the selected function mode can be confirmed by operating in a second operation type, that is, by pressing the operating device 32.
[0039] Each function mode 54 assigned to each of the functions 501, 502, 503, and 504 2a , 54 2b , 54 2c is assigned a function mode color coding. The function mode color coding can also be represented, for example, by a colored border 56 of a display tile representing each of the function modes 54 2a , 54 2b , 54 2c . In order to avoid the stimulation caused by the display of too many different color codings, in the function mode 54 assigned to each function 50, it is preferable to match each function mode color coding with the function color coding of the assigned function. In the state of FIG. 3, this means that the three function modes 54 2a , 54 2b , 54 2c are displayed with a function mode color coding corresponding to the function color coding of the function 502. At the same time, for example, after selecting and confirming the function 502, by appropriately controlling the first lighting unit 36, the first operating mechanism 28 is also illuminated with the color coding or color assigned to the function and the function modes 54 2a , 54<After selecting and confirming one of the functions 50, and then selecting and confirming one of the function modes 54 assigned to the selected and confirmed function, the selected and confirmed function must be activated along with the selected and confirmed function mode. In the case of spraying, this means that even after selecting the spraying and spraying intensity and confirming the selection, the spraying has not yet started. For example, when the construction machine 10 reaches the place where spraying should be performed, the spraying is activated by operating one of the second operating mechanisms 48 on the control panel 51, or stopped if it is already in operation. In this regard, Figure 5 shows a control panel 51 with four second operating mechanisms 481, 482, 483, and 484, which are assigned to functions 501, 502, 503, and 504 and configured as push buttons. Here again, in order to achieve a consistent appearance, it is advantageous that each of the second operating mechanisms 481, 482, 483, and 484 assigned to a specific function is illuminated by a second lighting unit 58, each provided with a color corresponding to the function color coding of the assigned function, or illuminated in a way that is visible to the operator 22. Here, for example, unless function 50 is selected and / or confirmed, the assigned second operating mechanism 48 may be set to be unlit or illuminated in an intermediate color, such as white. After function 50 is selected, the second operating mechanism 48 assigned to the selected function may be illuminated in a color corresponding to the function color coding of the assigned and selected function.
[0041] Using the first operating mechanism 28, the function 50 is selected and confirmed, the function mode 54 assigned to the function is selected and confirmed, and the selected and confirmed function is activated along with the selected and confirmed function mode. Then, by operating the provided second operating mechanism 48, the function is activated and the assigned system area is activated, or it is deactivated and stopped again by operating it again.
[0042] Figure 4 shows that function 503 is selected and confirmed by appropriate operation of the first operating mechanism 28, and correspondingly, function mode 54 is assigned to function 503. 3a, 54 3b , 54 3c This indicates a state in which it is displayed or highlighted. These three function modes 54 3a , 54 3b , 54 3c After selecting and confirming one of the options, the assigned function can be activated along with the selected and confirmed function mode by acting on the second operating mechanism 483.
[0043] For functions that are not assigned a distinct function mode, for example, it is possible to configure the system so that the function mode is not displayed on screen 42 after the corresponding function is selected. This allows the operator 22 to be informed that the selected and confirmed function can be directly activated or deactivated again by acting on the assigned second operating mechanism 48.
[0044] After selecting, confirming, and activating a function or function mode, a return function may be provided, which can be activated by, for example, a button 60 located in the area of the first operating mechanism 28 of the armrest 38, so that one or more other functions or function modes can also be activated. The return function is a function that returns to the previous display screen, for example, function mode 54 assigned to function 502 depending on the state in Figure 3. 2a , 54 2b , 54 2c These function modes 54 are displayed. 2a , 54 2b , 54 2c By selecting and confirming one of the options, and activating the function as necessary, and then activating the return function, the first operating mechanism 28 will be activated so that one of the selectable functions 501, 502, 503, or 504 is displayed, and for example, the system will return to a state where the assigned function mode is not displayed, and then, for example, if function 502 remains active, function 503 will be selected and confirmed, and the function mode 54 assigned to that function will be activated. 3a , 54 3b , 54 3c After these function modes 54 are displayed, 3a , 543b , 54 3c One of these can be selected and confirmed, and by acting on the second operating mechanism 483, the function can be activated along with the selected and confirmed function mode.
[0045] In particular, if the screen 42 is configured as a touchscreen equipped with a touch sensor surface 46, the operating system 26 may be configured to perform the selection and confirmation process described above not only using the first operating mechanism 28 but also by acting on the touch sensor surface 46. For example, after the four functions 501, 502, 503, and 504 are displayed, the function 502 can be selected by touching the touch sensor surface 46 of the tile area representing the function 502. After the selection is made, it is possible to confirm this selection by touching the tile representing the function 502 again, or it is possible to recognize that the selection has already been confirmed by touching the touch sensor surface 46 once. Next, the assigned function mode 54 2a , 54 2b , 54 2c To select one of the following, use function mode 54 2a , 54 2b , 54 2c A touch sensor surface 46 is made within the area of one of the tiles representing the function, and confirmation is made by making a touch once or by making another touch. The function selected and confirmed in this way using the screen 42, along with the selected and confirmed function mode, is activated by operating the second operating mechanism 482 assigned to that function.
[0046] Alternatively, the return function can also be selected by touching the screen 42 or the touch sensor surface 46 in the area of the tile 62 that represents the return function. Alternatively or additionally, the control panel 51 may be provided with a button 64 that represents the return function or activates the return function in a corresponding operation.
[0047] Depending on the type of construction machine 10, various functions may be selectable using the operating system, so it may be advantageous not to provide a dedicated second operating mechanism 48 assigned to each selectable function on the control panel 51. For example, as shown in Figures 6a and 6b, a single second operating mechanism 48 equipped with a second lighting unit 58 may be provided. After selecting one of the selectable functions 50, for example function 502 in the state of Figure 3, the second lighting unit 58 provided on the single second operating mechanism 48 can be operated or made to operate so that the second operating mechanism 48 illuminates in a color corresponding to the function color coding of the function 502 selected in that state. In this case, it is not important whether this selection and, if necessary, confirmation was made using the first operating mechanism 28 or the screen 42 configured as a touchscreen. By acting on the second operating mechanism 48, in the state of Figure 6a, function 502 can be enabled or disabled in the selected and confirmed function mode. As shown in Figure 6b, function 503 is selected and confirmed, and there are three function modes 54 3a , 54 3b , 54 3c When any of the above is selected and confirmed, it is also possible to enable and then disable the function by acting on the second operating mechanism 48 of the control panel 51, which is illuminated in the color corresponding to the function color coding of the function 503 in that state.
[0048] In relation to the second operating mechanism 48, regardless of whether a separate second operating mechanism 48 is assigned to each selectable function 50, or whether one or, as necessary, multiple second operating mechanisms 48 are assigned to each of the multiple selectable functions 50, the second operating mechanism 48 may be configured to illuminate in the color assigned to each function only when the selection and confirmation of the selection have been fully performed. If there are multiple selectable function modes 54 for a selectable function 50, the assigned or to-use second operating mechanism 48 is either not illuminated or illuminated in an intermediate color while the function mode to be selected has not been selected and confirmed. Only when it is clearly defined which function to activate in which function mode is the assigned second operating mechanism 48 illuminated in the corresponding color, thereby enabling the operator 22 to recognize that, at this point, the system area of the construction machine 10 assigned to the selected function can finally be activated. If there are no function modes for a selectable function 50, the assigned second operating unit 48 is already illuminated in the corresponding color after the function has been selected and confirmed, informing the operator 22 that the selected and confirmed function can be activated.
[0049] In the operating system 26, it is also possible to configure the first operating mechanism 28 to be illuminated in an intermediate color, especially when a function has not been selected and / or confirmed. The transition to illumination in a color corresponding to the function color coding of the selected function may occur when the function is selected by the operation of the actuator 32 in a first type of operation, or only when the selection of the function is confirmed by the operation of the actuator 32 in a second type of operation. In the case of function selection using the screen 42 configured as a touchscreen, the transition from illumination in an intermediate color, i.e., white, to illumination in a color corresponding to the function color coding of the selected function may occur, for example, when the function is selected by touching the screen 42 once and confirmed by touching it once if necessary, or only when the selection of the selected function is confirmed by touching it again after the selection has been made.
[0050] Finally, it should be noted that the operating system 26 may also have other operating elements, for example, by being incorporated into an armrest 38 as shown in Figure 7. For example, the control panel 51 may incorporate an emergency stop switch 66, which, when operated, immediately stops all system areas or the entire construction machine 10. A start / stop switch 68, or a switch 70 for activating and releasing the emergency brake, and a driving lever 72 operated by the operator 22 like a joystick to move the construction machine 10 can also be incorporated into the armrest 38.
