Abstract

PROBLEM TO BE SOLVED: To perform selection which becomes impossible at low cost while suppressing deterioration of comfort for a user when a part of the selection on a display picture by an operation device becomes impossible due to a failure of the operation device in a GUI of which the display and the operation device are provided at remote places.SOLUTION: When a part of switches of a four directional operation key is failed, a transition model for every kind of picture for selection is made unnecessary by transiting a picture for selection on which a first mask image is superposed to a picture for selection on which a second mask image is superposed only with switches which do not detect a failure, and selecting an image for operating the failure direction which becomes impossible to be selected with a switch which detects the failure.

Description

  The present invention relates to a vehicle operation input device and a vehicle operation input system used in a GUI (Graphical User Interface).

  Conventionally, as an HMI (Human Machine Interface) of a vehicle, graphics such as icons and buttons indicating functions of on-board devices such as a car air conditioner and a car audio are collectively displayed on a display screen. There is known a GUI capable of operating each vehicle-mounted device by selecting a graphic indicating a target function.

  In such a GUI, there is a problem that if the graphic indicating the target function cannot be selected due to a failure of the operation device, the target function cannot be used. Therefore, as means for solving this problem, for example, in Patent Document 1, when an abnormality occurs in an operation input system including a touch panel, operation keys are displayed at positions avoiding the range of the touch panel that has become unavailable due to the abnormality. A technique for changing the screen layout so that the position is changed is disclosed. In addition, Patent Document 2 discloses a technique for displaying an operation button displayed at a position corresponding to an abnormal portion on a display surface at a position corresponding to a normal portion when a failure occurs in the touch panel. ing.

  Further, GUIs other than those in which a display and an operation device are integrated, such as a touch panel, are known as vehicle GUIs. For example, while using a head-up display (HUD) as a display, the display and the operation device are separated in order to minimize the movement of the driver's line of sight, such as using a switch provided on the center console or steering as the operation device. A GUI provided at a position is also known.

JP 2009-119931 A JP 2009-3756 A JP 2001-337761 A JP-A-6-286534 JP 2010-157362 A Japanese Patent Laid-Open No. 7-71572 JP 2007-285969 A

  In the GUI provided at a position where the display and the operation device are separated from each other, a fixed switch such as a key switch or a button switch is used unlike the touch switch of the touch panel. There is a problem that the disclosed technology cannot be applied. Further, although it is conceivable to provide an extra switch in advance in the operation device in preparation for a failure, there is a problem in that the cost is increased due to the provision of an extra switch.

  In addition, when a failure occurs in some switches of the operation device, the display screen may be hierarchized so that a graphic indicating the target function can be selected only by selection with a switch in which no failure has occurred. It is done. Here, the graphic indicating the function is assigned in four directions (upper, lower, left and right) on the screen (functions A, C, B, and D, respectively). A GUI (see FIG. 1) that can be selected by each will be described as an example.

  For example, when a failure occurs in the switch that selects the upper direction, a graphic indicating both the function A of the bag and the function C that is allocated in the downward direction is assigned to the downward direction, for example, in the downward direction. It is conceivable to display a screen assigned in the downward direction. When the downward direction is selected, the screen changes to a screen other than the upward direction, for example, the function A assigned to the left direction and the function C assigned to the right direction. When the left direction is selected, the function A is selected. If the right direction is selected, the function C may be selected.

  However, in this case, when it is assumed that a failure occurs in only one switch, a screen that is layered by four patterns, which are the failure patterns of the upper, lower, left, and right switches, for one type of screen ( It is necessary to prepare 6 sheets (a to f in FIG. 1) and their transition models (4 patterns). Therefore, many man-hours for development and memory are required, and there is a problem that costs increase. In addition, since the screen layout is largely changed, there is a problem that the visibility for the user is lowered and the possibility that the comfort is lowered is high.

  The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide a GUI provided in a position where the display and the operation device are separated from each other on the display screen by the operation device due to a failure of the operation device. A vehicle operation input device and a vehicle operation input system that enable selection at a low cost while suppressing a decrease in comfort for the user when some selections are disabled Is to provide.

  The vehicle operation input device according to claim 1 includes failure detection means for detecting individual failures of the plurality of switches of the operation device, and holds the data of the first mask image and the data of the second mask image. ing. When the failure detection unit detects a failure of a part of the plurality of switches, the display control unit displays the first mask image superimposed on the selection screen and does not detect the failure. In accordance with the selection by the selection means in accordance with the signal from the switch, the screen is shifted to the selection screen on which the second mask image is superimposed and displayed. Then, the failure direction operation image is selected by selecting a section including only the failure direction operation image among the sections divided by the second mask image.

  In the data of the first mask image, the failure direction operation image that is the operation image assigned in the direction corresponding to the switch in which the failure is detected is assigned in the direction corresponding to the switch in which the failure is not detected. A guide to selectively select the section with a switch that does not detect a failure, and a partition that divides the selection screen into multiple sections so that it is combined with a non-failure direction operation image that is an operation image. Is data of a mask image for superimposing and displaying.

  The data of the second mask image includes a section including the failure direction operation image and a failure direction operation image for a section corresponding to a section including the failure direction operation image and the non-failure direction operation image. To select a partition that includes the failure direction operation image and a partition that does not include the failure direction operation image using a switch that does not detect a failure, and a partition that further includes a failure direction operation image. It is the data of the mask image for displaying a guidance superimposed.

  According to the above configuration, when a part of the plurality of switches of the operation device fails, the second screen is selected from the selection screen on which the first mask image is superimposed only by the switch that has not detected the failure. It is possible to select a failure direction operation image that can no longer be selected by the switch in which the failure is detected by transitioning to the selection screen on which the mask image is superimposed.

  Here, when the screen hierarchy corresponding to the switch failure in each direction is simply performed, a screen that is layered by the switch failure pattern is required for one type of selection screen. At the same time, the number of screen transition models corresponding to the pattern is required. On the other hand, according to the configuration of claim 1, since the first mask image and the second mask image are used by being superimposed on the selection screen, a transition model for each type of selection screen is not required, Costs due to increased development man-hours and memory can be reduced.

  According to the configuration of the first aspect, even when the operation image cannot be selected by the switch in which the failure is detected, the operation image can be selected by the switch in which the failure is not detected. become. In addition, since the switch is replaced by a switch in which a failure of the operation device is not detected, there is no cost for providing an extra switch.

  Furthermore, according to the configuration of claim 1, since only the first mask image and the second mask image are superimposed on the selection screen, the screen layout of the selection screen such as the arrangement of the operation images can be greatly changed. Absent. Therefore, it is difficult to impair the visibility of the selection screen for the user.

  As a result, in the GUI provided at a position where the display and the operation device are separated from each other, when a part of the selection on the display screen by the operation device becomes impossible due to the failure of the operation device, the selection that cannot be selected Can be performed at a low cost while suppressing a decrease in comfort for the user.

  Here, the operation device is composed of switches for up, down, left and right directions, and the display control means displays a selection screen for selecting a target operation image from among the four types of operation images. In the case of displaying on the screen, if the operation images are assigned and displayed in the four directions of up, down, left and right on the screen, for example, there are modes of claims 2 to 5.

  According to the configuration of the second aspect, when the switch in at least one of the upper and lower directions fails, the second upper and lower fault can be detected from the selection screen on which the first upper and lower fault mask image is superimposed only by the left and right switches. Transition to the selection screen superimposed with the time mask image or the selection screen superimposed with the third upper and lower failure mask image, and the operation image that cannot be selected with the switch that detected the failure (hereinafter referred to as the failure direction operation image) ) Can be selected.

  Here, when screens are simply hierarchized according to switch failure of three patterns, such as switch failure in the upward direction, downward direction, upward and downward direction, as shown in FIG. On the other hand, a screen transition model with three patterns corresponding to the failure of each pattern switch is required. As for the screen, a screen layered for each pattern is required. Except for a screen that can be used in common, five screens are displayed as shown in FIG. 2 (see g to k in FIG. 2). Is newly required.

  On the other hand, according to the configuration of the second aspect, for the first up / down failure that can be used in common for the failure of the three patterns of switches such as the failure of the upward, downward, upward and downward switches. Only three images are required: a mask image, a second vertical failure mask image, and a third vertical failure mask image. In addition, since the first vertical failure mask image, the second vertical failure mask image, and the third vertical failure mask image are used by being superimposed on the selection screen, each pattern switch is selected for each type of selection screen. No transition model is required for each failure. Therefore, one pattern transition model and three new images can be added, and the cost due to an increase in development man-hours and memory can be suppressed.

  In the configuration of claim 3, as in the configuration of claim 2, when a switch in at least one of the upper and lower directions fails, the first upper and lower failure mask image is superimposed only by the left and right switches. Transition from the selection screen to the selection screen on which the second vertical failure mask image is superimposed or the selection screen on which the third vertical failure mask image is superimposed, and the failure direction operation that can no longer be selected by the switch that detects the failure It becomes possible to select the image. Therefore, even with the configuration of claim 3, it is possible to add one pattern transition model and three new images to three patterns of switch failures such as upward, downward, upward and downward switch failures. It is possible to reduce the cost due to the increase in development man-hours and memory.

  According to the configuration of claim 4, when the switch in at least one of the left and right directions fails, the second left and right failure can be detected from the selection screen on which the first left and right failure mask image is superimposed only by the upper and lower switches. Transition to the selection screen on which the time mask image is superimposed or the selection screen on which the third left and right failure mask image is superimposed, and it becomes possible to select the failure direction operation image that can no longer be selected by the switch that has detected the failure. .

  Here, in case of simply layering the screen according to the failure of the three patterns of switches, such as the failure of the left, right, left and right switches, the upward, downward, upward and downward directions Similar to the case of a switch failure, a transition pattern of three patterns of screens corresponding to each pattern of switch failure is required for one type of screen, such as left, right, left and right switch failures. It becomes. In addition, the screen needs to be hierarchically layered for each pattern. Except for screens that can be used in common, 5 is the same as in the case of switch failure in the upward, downward, upward, and downward directions. A new screen is required.

  On the other hand, according to the configuration of claim 4, the first left and right failure can be used in common for three patterns of switch failures such as failure of the upward, downward, upward and downward switches. Only three images are required: a mask image, a second left and right failure mask image, and a third left and right failure mask image. Further, since the first left and right failure mask image, the second left and right failure mask image, and the third left and right failure mask image are used by being superimposed on the selection screen, the left and right directions are selected for each type of selection screen. There is no need for a transition model corresponding to switch failure of each pattern, such as switch failure in the direction, left and right. Therefore, one pattern transition model and three new images can be added, and the cost due to an increase in development man-hours and memory can be suppressed.

  Also in the configuration of claim 5, as in the configuration of claim 4, when the switch in at least one of the left and right directions fails, the first left and right failure mask image is superimposed only by the upper and lower switches. Transition from the selection screen to the selection screen on which the second left and right failure mask image is superimposed or the selection screen on which the third left and right failure mask image is superimposed, and the failure direction operation that cannot be selected by the switch that detects the failure It becomes possible to select the image. Therefore, the configuration of claim 5 can also add one pattern transition model and three new images to three patterns of switch failures such as left, right, left and right switch failures. It is possible to reduce the cost due to the increase in development man-hours and memory.

  According to the configuration of the sixth aspect, when the failure detection means detects a switch failure, the display control means displays the switch failure on the display, so that the operation image is selected by the switch. It becomes possible for the user to quickly recognize that it is impossible.

  The vehicle operation input system according to claim 7 includes a display for displaying an operation image, which is an image for performing an operation input to the vehicle-mounted device, and a plurality of switches operated by the user, and is separate from the display. The operation device provided and the vehicle operation input device according to any one of the above are included. Therefore, in the GUI provided in a position where the display and the operation device are separated from each other, when a part of the selection on the display screen by the operation device becomes impossible due to the failure of the operation device, the selection which cannot be selected is selected. This is possible at a low cost while suppressing a decrease in comfort for the user.

It is a schematic diagram. The screen of the display is simply hierarchized according to the failure of the three patterns of switches, such as the failure of the upward, downward, upward and downward switches, and the graphic indicating the target function can be selected only by selecting with the left and right direction switches.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 3 is a block diagram showing a schematic configuration of the vehicle operation input system 100 to which the present invention is applied. A vehicle operation input system 100 shown in FIG. 3 is mounted on a vehicle, and includes a display 1, an operation device 2, and a control device 3.

  The vehicle operation input system 100 employs a GUI, and performs graphic input such as icons and buttons indicating functions of the vehicle-mounted device such as a car air conditioner and a car audio on the screen of the display 1 (that is, operation input to the vehicle-mounted device is performed. Operation images) are displayed in an integrated manner, and the user can operate each vehicle-mounted device by selecting an operation image indicating a target function with the operation device 2.

  The display 1 displays an image in accordance with an instruction from the control device 3 and is provided in the vehicle interior. For example, the display 1 may be configured to use a head-up display (HUD), or may be configured to use a display used in an in-vehicle navigation device. Moreover, it is good also as a structure which uses the display provided in the instrument panel etc. separately from the display used for a vehicle-mounted navigation apparatus.

  The operation device 2 is a pointing device used for selecting an operation image on the screen of the display 1, and is provided separately from the display 1. The operation device 2 may be configured to be provided, for example, in a vehicle steering or a center console.

  The operation device 2 includes a switch (SW), and a plurality of directions can be designated. For example, the operation device 2 may be configured by a switch such as a push SW, a rotary SW, or a tilt SW, or may be configured by combining these. As an example, it may be configured by a plurality of push SWs for each designated direction, or may be configured by a rotary SW having a contact for each designated direction.

  In this embodiment, the operation device 2 is exemplified by a case where the operation device 2 includes six types of push SWs “upward”, “downward”, “leftward”, “rightward”, “decision”, and “return”. Continue with the following explanation. Here, a schematic configuration of the operation device 2 will be described with reference to FIG. FIG. 4 is a schematic diagram for explaining a schematic configuration of the operation device 2.

  As shown in FIG. 4, the operation device 2 includes six types of switches: an upward direction SW 21, a downward direction SW 22, a left direction SW 23, a right direction SW 24, a determination SW 25, and a return SW 26.

  The up direction SW21, the down direction SW22, the left direction SW23, and the right direction SW24 are switches for selecting an operation image by designating each of the up, down, left, and right directions on the screen of the display 1. Hereinafter, the four switches of the upward direction SW21, the downward direction SW22, the leftward direction SW23, and the rightward direction SW24 are referred to as four-direction operation keys. The determination SW 25 is a switch for determining selection and the like. The return SW 26 is a switch for returning to the screen before the transition when transitioning to a screen for further selection by selection of the operation image.

  When the user operates the switch of the operation device 2, a signal (that is, operation information) corresponding to the operated switch is sent to the control device 3. For example, it is assumed that a signal line for transmitting a signal is provided for each switch, and operation information is sent to the control device 3 via the signal line.

  Returning to FIG. 3, the control device 3 is composed mainly of a microcomputer comprising a CPU, ROM, RAM, EEPROM, etc., and various control programs stored in the ROM based on information input from the operation device 2. Are executed, various processes such as a process related to the selection of the operation image, a process related to the execution of the function of the vehicle-mounted device indicated by the operation image, and an alternative process when the operation device 2 fails are executed. As shown in FIG. 3, the control device 3 includes a display control unit 31, a screen operation unit 32, and a failure detection unit 33. The control device 3 corresponds to the vehicle operation input device in the claims.

  For example, as illustrated in FIG. 5, the display control unit 31 causes the display 1 to display a selection screen in which an operation image is arranged at a position corresponding to each direction of the four-direction operation key of the operation device 2. FIG. 3 is a diagram illustrating an example of the selection screen displayed on the display 1. The display of the functions A to D in FIG. 3 corresponds to the operation image. In the example of the selection screen shown in FIG. 5, the function A is arranged in the upward direction, the function B in the right direction, the function C in the downward direction, and the function D in the left direction. The display control unit 31 corresponds to the display control means in the claims.

  When the operation image is selected in the screen operation unit 32, the display control unit 31 transitions to a new selection screen when it is necessary to display a further selection screen for the operation image. Let Further, the display control unit 31 transitions the screen from the selection screen based on the information on the failure detection result in the failure detection unit 33 depending on whether or not the switch of the operation device 2 has failed. Make model changes. In addition, when there is an instruction from the failure detection unit 33, the display control unit 31 displays a notification screen for failure of the operation device 2. Details of the screen transition model and the failure notification screen will be described later.

  The screen operation unit 32 selects an operation image in accordance with operation information from the four-way operation keys of the operation device 2. Therefore, the screen operation unit 32 corresponds to the selection unit in the claims. Specifically, when operation information is input from the upper direction SW 21, an operation image arranged in the upper direction of the selection screen is selected, and when operation information is input from the lower direction SW 22. The operation image arranged in the lower direction of the selection screen is selected. When operation information from the left direction SW23 is input, an operation image arranged in the left direction on the selection screen is selected, and when operation information from the right direction SW24 is input, The operation image arranged in the right direction of the selection screen is selected.

  In addition, when operation information from the return SW 26 is input, an instruction to return to the screen before the transition is sent to the display control unit 31 to return to the screen before the transition. Further, in a situation where selection needs to be determined, if operation information is input from the determination SW 25, the selection is determined. For example, when operation information from the determination SW 25 is input in a situation where no further selection screen is displayed for the operation image, the execution of the function indicated by the operation image may be determined. When the determination is made, an instruction to execute the function is sent to the target vehicle-mounted device to execute the target function. In the following, an event such as selection of an image for operation on the top, bottom, left or right, determination of selection, or return to the screen before transition performed according to the switch operation of the operation device 2 is referred to as an operation event.

  The screen operation unit 32 performs processing according to the presence or absence of a switch failure of the operation device 2 based on the information on the failure detection result in the failure detection unit 33. For example, when the failure detection unit 33 does not detect a failure of any switch of the operation device 2, the screen operation unit 32 corresponds to the above-described correspondence with the operation information of the four-way operation key of the operation device 2. Operation events are assigned so that Hereinafter, operation event assignment when no switch failure of the operation device 2 is detected is referred to as normal assignment.

  If the failure detection unit 33 has not detected a failure of any switch of the operation device 2, the display control unit 31 selects according to the screen transition model (hereinafter referred to as normal model) corresponding to the normal allocation. Make transitions for the screen. Here, the normal model will be described with reference to FIG. FIG. 6 is a schematic diagram for explaining an example of a normal model. FIG. 6 shows an example in which the screen transitions from the selection screen shown in FIG.

  For example, when the operation information from the upper direction SW 21 is input, the screen transits to a screen for determining the execution of the function A arranged in the upper direction of the selection screen, and the operation information from the lower direction SW 22 is displayed. If input, the screen transitions to a screen for determining execution of the function C arranged in the lower direction of the selection screen. When the operation information from the left direction SW 23 is input, the screen transitions to a screen for determining the execution of the function D arranged in the left direction of the selection screen, and the operation information from the right direction SW 24 is displayed. If input, the screen transitions to a screen for determining execution of the function B arranged in the right direction of the selection screen.

  On the other hand, the display control unit 31 and the screen operation unit 32 perform substitution processing when the failure detection unit 33 detects a failure of any switch of the operation device 2. The substitute process in the display control unit 31 represents a process of transitioning a screen according to a screen transition model in which a screen transition model for failure is inserted into the normal model instead of the normal model. Further, the alternative process in the screen operation unit 32 is a process of reassigning operation events so as to transition the screen for failure according to operation information from a switch in which no failure is detected among the four-way operation keys. Indicates. In the present embodiment, for the sake of convenience, a description will be given by taking as an example a configuration in which substitution processing is performed when the failure detection unit 33 detects a failure of the four-way operation key of the operation device 2.

  Here, the process related to the alternative process in the control device 3 will be described with reference to FIG. FIG. 7 is a flowchart illustrating an example of a flow of processing related to substitution processing in the control device 3. In addition, this flow is started when the ACC power supply of the own vehicle is turned on, for example, and is ended when the ACC power supply is turned off.

  First, in step S1, the failure detection unit 33 makes a failure determination as to whether or not there is a failure in any of the switches of the four-way operation key, and then proceeds to step S2. The failure determination is performed according to whether or not a failure is detected by the failure detection unit 33. Therefore, the failure detection unit 33 corresponds to the failure detection means in the claims. The failure includes, for example, sticking that does not return while the push switch is pushed in, or disconnection of a signal line that connects the four-way operation key and the control device 3. In addition, there is an abnormality that the on / off of the signal output from the four-way operation key is switched at a speed exceeding the limit of the user operation, and when the four-way operation key is a contact switch, the contact portion is damaged.

  For example, the fixation may be detected based on the signal output from the four-way operation key being kept on for a certain period of time. An abnormality in which on / off of the signal output from the four-way operation key is switched at a speed exceeding the limit of the user operation may be detected based on the frequency of on / off switching. The disconnection or the breakage of the contact portion may be detected based on the current application state. Moreover, it is good also as a structure which performs the detection of the failure in the failure detection part 33 using the well-known method as disclosed by patent documents 3-7.

  If it is determined in step S2 that there is a failure (YES in step S2), the process proceeds to step S3. If it is not determined that there is a failure in the failure determination (NO in step S2), the process proceeds to step S7.

  In step S <b> 3, the failure detection unit 33 notifies the display control unit 31 of the switch failure of the operation device 2. In addition to information indicating that a failure has been detected, the failure notification includes, for example, information for specifying a switch that has detected a failure. Then, based on the failure notification, the display control unit 31 displays a notification screen for failure of the operation device 2 on the display 1, and proceeds to step S4.

  On the failure notification screen, a display indicating a failure of the switch of the operation device 2 is performed. The information for specifying the switch that has detected the failure may be configured to be used for notifying the content that notifies the switch that has detected the failure. For example, it is configured to notify the user of the switch failure of the operation device 2 by displaying a text indicating the switch failure of the operation device 2 such as “operation device failure” or “upward key is broken”. That's fine. According to this, the user can quickly recognize that the operation image cannot be selected by the switch. In addition to the text display, it may be configured to display a switch failure by displaying an image such as an icon.

  In step S4, it is determined whether or not the failure detection unit 33 has detected a failure in the left SW 23 or the right SW 24 (that is, whether or not the left / right switch is in failure). If a failure of at least one of the left SW 23 and the right SW 24 (hereinafter referred to as the left / right switch) has been detected (YES in step S4), the process proceeds to step S5. If a failure in at least one of the upward SW 21 and the downward SW 22 (hereinafter referred to as the up / down switch) is detected (NO in step S4), the process proceeds to step S6.

  In step S5, right / left system failure processing is performed, and the flow returns to step S1 to repeat the flow. In the left / right system failure process, the display control unit 31 uses a screen transition model in which a screen transition model (hereinafter, a left / right system failure model) when the left / right switch fails is inserted into a normal model. Further, the screen operation unit 32 invalidates the operation information from the upward direction SW21 and the downward direction SW22, and instructs to change the screen in the left and right system failure model according to the operation information from the left direction SW23 and the right direction SW24. The data is sent to the display control unit 31.

  Here, an outline of the processing at the time of the right and left system failure will be described with reference to FIGS. 8 and 9A to 9C. FIG. 8 is a schematic diagram showing an overview of the processing at the time of a left and right system failure. FIG. 9A is a diagram illustrating an example of the first left / right failure mask image. FIG. 9B is a diagram showing an example of a second left / right failure mask image. FIG. 9C is a diagram illustrating an example of a third left / right failure mask image. Here, an example is shown in which the screen transitions from the selection screen shown in FIG.

  First, in the case of a failure of the left / right switch (that is, a failure of the left / right system), a selection screen similar to the normal model selection screen (see FIG. 5) is displayed as shown in FIG. (1) The display control unit 31 displays a screen on which the left and right failure mask images are superimposed (hereinafter, a left and right system failure selection screen).

  The first left-right failure mask image is composed of a set of divisions of an upward operation image and a left operation image on the screen, and a downward operation image and a right operation image on the screen. It is a mask image for superimposing and displaying an upper direction mark and a lower direction mark for separating a partition from a set and a partition for selectively selecting these partitions.

  Subsequently, when the operation information from the upper direction SW 21 is input on the left and right system failure selection screen, the screen operation unit 32 includes a section marked with an upper mark on the left and right system failure selection screen. Among the sections marked with the downward mark, the section marked with the upward mark is selected. Then, the display control unit 31 displays a screen (hereinafter, the left / right system failure upper / left screen) in which the second left / right failure mask image as shown in FIG. 9B is superimposed on the selection screen.

  The second left-right failure mask image is obtained by dividing the upper operation image section and the left direction image into sections corresponding to a set of the upper operation image and the left operation image on the screen. Separation further divided into sections for the operation image, and an upward mark and a downward mark for selectively selecting the upper operation image section and the left operation image section Is a mask image for superimposing and displaying. Further, the second left / right failure mask image masks a section corresponding to a pair of a lower operation image and a right operation image on the screen.

  On the other hand, when the operation information from the down direction SW 22 is input on the left and right system failure selection screen, the screen operation unit 32 is divided into a section marked with an upward mark on the left and right system failure selection screen. Of the sections marked with the direction mark, the section marked with the downward mark is selected. Then, the display control unit 31 displays a screen (hereinafter, the left / right system failure bottom / right screen) in which the third left / right failure mask image as shown in FIG. 9C is superimposed on the selection screen.

  The third left-right failure mask image is obtained by dividing the lower operation image section and the right direction image into sections corresponding to a set of the lower operation image and the right operation image on the screen. Separation further divided into operation image sections, and an upward mark and a downward mark for selectively selecting the operation image section in the lower direction and the operation image section in the right direction. Is a mask image for superimposing and displaying. Further, the third left / right failure mask image masks a section corresponding to a pair of sections of the upward operation image and the left operation image on the screen.

  Subsequently, when the operation information from the upper SW 21 is input on the left / right system failure upper / left screen, the screen operation unit 32 is marked with an upward mark on the left / right system failure upper / left screen. Among the sections and sections marked with a downward mark, a section marked with an upward mark (that is, the upward direction on the screen) is selected. At this time, an operation event (operation event “up”) for selecting an operation image in the upward direction on the screen is performed, and a transition is made to a screen for determining the execution of function A.

  When operation information is input from the downward SW 21, the screen operation unit 32 is divided into sections with an upward mark and a downward mark when the left / right system is faulty. The section marked with a downward mark (that is, the left direction on the screen) is selected. At this time, an operation event (operation event “left”) for selecting a left operation image on the screen is performed, and a transition is made to a screen for determining the execution of the function D.

  On the other hand, when operation information from the upper SW 21 is input on the lower / right screen at the time of the left / right system failure, the screen operation unit 32 is a section marked with the upper mark on the lower / right screen at the time of the left / right system failure. And a section marked with an upward mark (that is, a right direction on the screen) are selected. At this time, an operation event (operation event “right”) for selecting an operation image in the right direction on the screen is performed, and a transition is made to a screen for determining the execution of the function B.

  When the operation information is input from the downward SW 21, the screen operation unit 32 is divided into a section marked with an upward mark and a downward mark when the left / right system has failed. The section marked with the downward direction (that is, the downward direction on the screen) is selected. At this time, an operation event (operation event “down”) for selecting a downward operation image on the screen is performed, and a transition is made to a screen for determining the execution of the function C.

  The screen transition model as described above corresponds to the left-right system failure model. In the present embodiment, an example in which the screen transitions from the selection screen illustrated in FIG. 5 has been described, but the present invention is not necessarily limited thereto. Even when the types of selection screens are different, the first left-right failure mask image, the second left-right failure mask image, and the third left-right failure mask image are superimposed on the selection screen as described above. Such a left-right system failure model can always be applied.

  Further, the data of the first left and right failure mask image, the second left and right failure mask image, and the third left and right failure mask image are stored in advance in a non-volatile memory such as a ROM of the control device 3, for example. I shall keep it.

  In step S6, upper / lower system failure processing is performed, and the flow returns to step S1 to repeat the flow. In the upper / lower system failure process, the display control unit 31 uses a screen transition model in which a screen transition model (hereinafter referred to as an upper / lower system failure model) when the up / down switch fails is inserted into a normal model. In addition, the screen operation unit 32 invalidates the operation information from the left direction SW23 and the right direction SW24, and instructs to change the screen in the upper and lower system failure model according to the operation information from the upper direction SW21 and the lower direction SW22. The data is sent to the display control unit 31.

  Here, an outline of the upper / lower system failure process will be described with reference to FIGS. 10 and 11A to 11C. FIG. 10 is a schematic diagram showing an overview of processing when an upper / lower system failure occurs. FIG. 11A is a diagram illustrating an example of a first mask image for a vertical failure. FIG. 11B is a diagram illustrating an example of a second mask image for a vertical failure. FIG. 11C is a diagram illustrating an example of a third mask image for upper and lower failure. Here, an example is shown in which the screen transitions from the selection screen shown in FIG.

  First, in the case of an up / down switch failure (that is, up / down system failure), a selection screen similar to the normal model selection screen (see FIG. 5) is displayed on the selection screen as shown in FIG. 1 The display control unit 31 displays a screen on which the upper and lower failure mask image is superimposed (hereinafter referred to as an upper and lower system failure selection screen).

  The first vertical failure mask image includes an upper operation image and a left operation image set on the screen, a lower operation image on the screen, and a right operation image. It is a mask image for superimposing and displaying a delimiter that delimits a section from a set, and a left mark and a right mark for selectively selecting these sections.

  Subsequently, when the operation information from the left direction SW 23 is input on the screen for selecting an upper / lower system failure, the screen operating unit 32 includes a section marked with a left direction mark on the screen for selecting an upper / lower system failure. Among the sections marked with the right direction mark, the section marked with the left direction mark is selected. Then, the display control unit 31 displays a screen (hereinafter referred to as an upper / left failure upper / left screen) on which the second vertical failure mask image as shown in FIG. 11B is superimposed on the selection screen.

  The second upper / lower failure mask image is obtained by dividing the upper operation image section and the left direction image into sections corresponding to a set of the upper operation image and the left operation image on the screen. Separation further divided into sections for the operation image, and a left mark and a right mark for selectively selecting the upper operation image section and the left operation image section Is a mask image for superimposing and displaying. Further, the second upper / lower failure mask image masks a section corresponding to a pair of sections of a downward operation image and a right operation image on the screen.

  On the other hand, when the operation information from the right direction SW 24 is input on the screen for selecting an upper / lower system failure, the screen operation unit 32 displays the right-hand section and the section marked with the left direction on the screen for selecting an upper / lower system failure. Among the sections marked with the direction mark, the section marked with the right direction mark is selected. Then, the display control unit 31 displays a screen (hereinafter, the upper / lower system failure lower / right screen) on which the third upper / lower failure mask image as shown in FIG. 11C is superimposed on the selection screen.

  The third upper / lower failure mask image includes the lower operation image section and the right operation section in a section corresponding to a pair of a lower operation image and a right operation image on the screen. Separation further divided into sections for the operation image, and a left mark and a right mark for selectively selecting the lower operation image section and the right operation image section Is a mask image for superimposing and displaying. In addition, the third upper and lower failure mask image is configured to mask a section corresponding to a set of the upper operation image and the left operation image on the screen.

  Subsequently, when the operation information from the left direction SW 23 is input on the upper / left screen at the time of the upper / lower system failure, the screen operation unit 32 is marked with the left direction mark on the upper / left screen at the time of the upper / lower system failure. Among the sections and sections marked with the right direction mark, the section marked with the left direction mark (that is, the left direction on the screen) is selected. At this time, an operation event (operation event “left”) for selecting a left operation image on the screen is performed, and a transition is made to a screen for determining the execution of the function D.

  When the operation information is input from the right direction SW 24, the screen operation unit 32 is divided into a section with a leftward mark and a rightward mark on the upper / left screen when the vertical system has failed. The section with the mark in the right direction (that is, the upward direction on the screen) is selected. At this time, an operation event (operation event “up”) for selecting an operation image in the upward direction on the screen is performed, and a transition is made to a screen for determining the execution of function A.

  On the other hand, when the operation information from the left direction SW 23 is input on the lower / right screen at the time of the upper / lower system failure, the screen operation unit 32 is a section marked with the left direction mark on the lower / right screen at the time of the upper / lower system failure And a section marked with a left direction mark (ie, a downward direction on the screen) are selected. At this time, an operation event (operation event “down”) for selecting a downward operation image on the screen is performed, and a transition is made to a screen for determining the execution of the function C.

  Further, when operation information is input from the right direction SW 24, the screen operation unit 32 has a section with a left mark and a section with a right mark on the lower / right screen when the upper / lower system has failed. The section marked with the right direction (that is, the right direction on the screen) is selected. At this time, an operation event (operation event “right”) for selecting an operation image in the right direction on the screen is performed, and a transition is made to a screen for determining the execution of the function B.

  The screen transition model as described above corresponds to the upper and lower system failure model. In the present embodiment, an example in which the screen transitions from the selection screen illustrated in FIG. 5 has been described, but the present invention is not necessarily limited thereto. Even if the types of selection screens are different, the first vertical failure mask image, the second vertical failure mask image, and the third vertical failure mask image are overlapped on the selection screen as described above. Such an upper / lower system failure model can always be applied.

  Further, the data of the first vertical failure mask image, the second vertical failure mask image, and the third vertical failure mask image are stored in advance in a non-volatile memory such as a ROM of the control device 3, for example. I shall keep it. The first left and right failure mask image and the first upper and lower failure mask image correspond to the first mask image in the claims, and the second left and right failure mask image, the third left and right failure mask image, The second upper and lower failure mask image and the third upper and lower failure mask image correspond to the second mask image in the claims.

In step S7, normal processing is performed, and the flow returns to step S1 to repeat the flow. In the normal processing, the operation event assignment in the screen operation unit 32 is the normal assignment described above, and the screen transition model in the display control unit 31 is based on the normal model described above, and the four-way operation key input is performed. According to the above configuration, when the switch in at least one of the upper and lower directions of the four-way operation keys fails, only the left and right switches Transition from the selection screen on which the first vertical failure mask image is superimposed to the selection screen on which the second vertical failure mask image is superimposed or on the selection screen on which the third vertical failure mask image is superimposed. It becomes possible to select a failure direction operation image that cannot be selected by the detected switch.

  Here, an example when a failure occurs in the downward SW 22 will be described with reference to FIG. FIG. 12 is a diagram illustrating an example of an alternative using the left / right switch when a failure occurs in the downward SW 22. As shown in FIG. 12, when a failure in the downward SW 22 is detected, an upper / lower failure selection screen in which the first upper / lower failure mask image is superimposed on the selection screen is displayed on the display 1. Become.

  Subsequently, when the right direction SW 24 is pressed on the screen for selecting an upper and lower system failure, the lower / right screen when the upper and lower system failure is superimposed on the selection screen according to the input is displayed on the display 1. Will be displayed. Then, if the left direction SW23 is pressed on the lower / right screen at the time of the vertical system failure, the screen transitions to a screen for determining the execution of the function C, and the function C that should have been selected in the lower direction SW22 can be selected. It becomes possible.

  In addition, when a switch in at least one of the left and right directions fails, the second left and right failure mask image is superimposed from the selection screen on which the first left and right failure mask image is superimposed using only the upper and lower switches. It is possible to select a failure direction operation image that can no longer be selected by the switch that has detected the failure, by transitioning to the selection screen on which the selected selection screen or the third right / left failure mask image is superimposed.

  Here, when screens are simply hierarchized according to switch failure of three patterns, such as switch failure in the upward direction, downward direction, upward and downward direction, as shown in FIG. On the other hand, a screen transition model with three patterns corresponding to the failure of each pattern switch is required. As for the screen, a screen layered for each pattern is required. Except for a screen that can be used in common, five screens are displayed as shown in FIG. 2 (see g to k in FIG. 2). Is newly required.

  In addition, when simply stratifying screens according to three patterns of switch failures such as left, right, left and right switch failures, left and right for one type of screen. A transition model of three patterns of screens corresponding to switch failure of each pattern, such as switch failure in the direction, left and right directions, is required. In addition, the screen needs to be hierarchically layered for each pattern. Except for screens that can be used in common, 5 is the same as in the case of switch failure in the upward, downward, upward, and downward directions. A new screen is required.

  That is, when the screen is simply hierarchized according to the failure of the three patterns of switches, such as the failure of the switch in the upward direction, downward direction, upward and downward direction, leftward direction, rightward direction, leftward and rightward direction, 1 6 types of screen transition models and 10 screens are newly required for each type of screen.

  On the other hand, according to the above configuration, it is possible to use the first up / down failure that can be commonly used for the failure of the three patterns of switches such as the failure of the upward, downward, upward and downward switches. Only three images are required: a mask image, a second vertical failure mask image, and a third vertical failure mask image. Further, the first left and right failure mask image and the second left and right failure mask image that can be used in common for the failure of the three patterns of switches such as the left, right, left and right switch failures. Only three images are required, the image and the third left-right failure mask image. That is, only a total of 6 images are required.

  Further, in the case of a vertical failure, the first vertical failure mask image, the second vertical failure mask image, and the third vertical failure mask image are used in a superimposed manner on the selection screen, and the left and right failure In this case, the first left and right failure mask image, the second left and right failure mask image, and the third left and right failure mask image are used by being superimposed on the selection screen. No transition model is required according to the switch failure. Specifically, even if the number of types of screens for selection increases, it is possible to add two patterns of screen transition models, an upper and lower system failure model and a left and right system failure model, and six mask images. And cost due to increase in memory can be suppressed.

  Further, according to the above configuration, even when the operation image cannot be selected by the switch in which the failure is detected, the operation image can be selected by the switch in which the failure is not detected. . Further, since the substitution is performed by a switch in which a failure is not detected among the four-way operation keys, there is no cost for providing an extra switch. Furthermore, since the mask image is merely superimposed on the selection screen, the screen layout of the selection screen, such as the arrangement of the operation image, is not significantly changed. Therefore, it is difficult to impair the visibility of the selection screen for the user.

  As a result, in the GUI provided at a position where the display 1 and the operation device 2 are separated from each other, when a part of the operation device 2 cannot be selected on the display screen due to the failure of the operation device 2, the selection cannot be performed. This selection can be made at low cost while suppressing a decrease in comfort for the user.

  In the above-described embodiment, in the mask image for failure, the set of the upper operation image and the left operation image, the lower operation image, and the right operation image are divided. Although the configuration of dividing into a set of compartments is shown, it is not necessarily limited to this. For example, it may be configured to be divided into a set of a set of an upper operation image and a right operation image and a set of a lower operation image and a left operation image.

  Specifically, instead of the above-described first upper / lower failure mask image, a set of an upper operation image and a right operation image (hereinafter, upper / right operation) and a lower operation image. And the left and right operation images are overlapped with a partition that separates the section (hereinafter referred to as the lower / left section) and a left / right switch for selectively selecting these sections. A mask image for display is used.

  Further, instead of the above-described second upper / lower failure mask image, a partition further divided into an upper operation image section and a right operation image section with respect to a section corresponding to the upper / right section, In addition, a mask image for superimposing and displaying a left and right mark for selectively selecting the upper operation image section and the right operation image section with the left and right switches is used.

  Further, instead of the above-described third upper / lower failure mask image, a partition further divided into a lower operation image section and a left operation image section with respect to a section corresponding to the lower / left section, In addition, a mask image for superimposing and displaying a left and right mark for selectively selecting a section for the operation image in the lower direction and a section for the operation image in the left direction with the left and right switches is used.

  Also, instead of the above-described first left / right failure mask image, the above-mentioned upper / right section and the lower / left section are separated, and the up / down switch is used to selectively select these sections. A mask image for displaying the mark to be superimposed is used.

  Furthermore, instead of the above-described second left and right failure mask image, a partition further divided into an upper operation image section and a right operation image section for the section corresponding to the upper / right section, In addition, a mask image is used to superimpose and display an upper and lower mark for selectively selecting the upper operation image section and the right operation image section with the up and down switches.

  Then, instead of the above-described third left and right failure mask image, a section further dividing the section corresponding to the lower / left section into a section for the downward operation image and a section for the left operation image, In addition, a mask image is used to superimpose and display a mark indicating the upper and lower for selectively selecting the section of the operation image in the lower direction and the section of the operation image in the left direction with the up and down switches.

  Even in this case, in the GUI provided at a position where the display 1 and the operation device 2 are separated from each other as in the above-described embodiment, a part of the operation device 2 on the display screen due to the failure of the operation device 2. When the selection becomes impossible, it becomes possible to make the selection that becomes impossible to select at a low cost while suppressing a decrease in comfort for the user.

  In the above-described embodiment, an example in which the present invention is applied to the operation device 2 including four-way operation keys has been described. However, the present invention is not necessarily limited thereto. For example, the present invention may be applied to the operation device 2 including switches in three directions other than the four directions and in a plurality of directions including five or more directions.

  In this case, instead of the first vertical failure mask image and the first horizontal failure mask image described above, an operation image (hereinafter, referred to as a direction corresponding to the switch that did not detect the failure). A non-failure direction operation image) and a failure direction operation image are combined into a set of sections to divide the selection screen into multiple sections, and a mark for alternatively selecting the section with a switch that does not detect a failure A first mask image for superimposing and displaying the guidance is used.

  Further, instead of the above-described second vertical failure mask image, the third vertical failure mask image, the second left / right failure mask image, and the third left / right failure mask image, the failure direction operation image is not displayed. A section corresponding to a section including the failure direction operation image is divided into a section including the failure direction operation image and a section not including the failure direction operation image, and a switch that does not detect a failure. A second mask image for superimposing and displaying guidance such as marks for selectively selecting a section including the failure direction operation image and a section not including the failure direction operation image is used.

  In this configuration, when a failure of a part of the plurality of switches of the operation device 2 is detected, the first mask image is superimposed on the selection screen and the failure is not detected. In accordance with the selection according to the signal from the switch, the screen is shifted to the selection screen on which the second mask image is displayed in a superimposed manner. Then, the failure direction operation image is selected by selecting a section including only the failure direction operation image among the sections divided by the second mask image.

  Even with the above configuration, since the first mask image and the second mask image are superimposed on the selection screen, a transition model for each type of selection screen is not required, and the cost due to an increase in development man-hours and memory Can be suppressed. Further, since only the first mask image and the second mask image are superimposed on the selection screen, the screen layout of the selection screen, such as the arrangement of the operation images, is not greatly changed, and the selection screen for the user can be changed. Easy to see.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims, and the technical means disclosed in different embodiments can be appropriately combined. Such embodiments are also included in the technical scope of the present invention.
