Description

  The present invention relates to an on-vehicle remote control device, and more particularly to an on-vehicle remote control device having a self-diagnosis function for self-diagnosis of a failure of an operation input unit.

  In recent years, an increasing number of vehicles adopt an operation method in which a control content (for example, a command switch) displayed on a display device (for example, a monitor of a navigation device) that displays various information is input by touch operation (for example, see Patent Document 1). ). In such a vehicle, in order to reduce the movement of the driver's line of sight in particular, there is one in which an indicator is provided in the front part of the passenger compartment (front position far away from the driver's seat) close to the driver's field of view. (For example, refer to Patent Document 2). In a vehicle provided with a display device in this way, the driver's hand is difficult to reach the display device, and stable touch operation is not possible. Generally adopted. In this remote operation method, the operation input unit is mounted on the center console, and the pointer moves on the screen of the display device according to the operation of the operation input unit.

  In the operation input unit adopting the above-described remote operation method, it is assumed that the pointer operation cannot be performed for some reason. For this reason, it is necessary to mount a failure diagnosis function for confirming the detection state of the operation input unit. With regard to such a failure diagnosis function, in an electronic device (for example, an air conditioner panel) integrally having a display, a failure state of the electronic device is diagnosed by displaying the failure state of the electronic device on the display. (See, for example, Patent Document 3).

  By the way, when performing a failure diagnosis of the operation input unit, the remote control device described in Patent Document 2 does not have a display unit, so that data indicating the detection state of the operation input unit is transmitted to the communication means. It is necessary to display the failure state on the display device. Therefore, there is a problem that when the communication means fails, the failure state cannot be displayed on the display. In addition, when a failure occurs in communication via the communication means, it may be determined that the operation input unit is out of order.

  The present invention has been made to address the above-described problems, and an object thereof is to provide an in-vehicle remote control device that can perform failure diagnosis by using the remote control device alone without using a display and communication means. There is.

  In order to achieve the above object, an in-vehicle remote control device according to the present invention provides an operation input unit for performing a position instruction operation within a predetermined operation range, and applies an operation reaction force to the position operation of the operation input unit. A self-diagnosis mode for self-diagnosis of a failure of the operation input unit is settable, and the control unit is set to the self-diagnosis mode. Then, the reaction force applying unit is controlled based on a reaction force pattern set in association with each of a plurality of failure contents assumed in the operation input unit.

  Here, in the self-diagnosis mode, for example, the power to the control unit is turned on and a predetermined push-down switch provided in the operation input unit is pressed or a plurality of predetermined switches are pressed simultaneously. If the configuration is set occasionally, the operation for shifting from the normal mode (execution mode of normal processing in which the pointer on the display can be moved) to the self-diagnosis mode is simplified. Or it is good also as a structure set when the power supply to a control part is turned ON and the predetermined several switch of the push-down type provided in the operation input part is pushed in predetermined order. Also, for example, when the power to the control unit is turned off, or when a predetermined push-down switch provided in the operation input unit is pressed, or when the operation input unit is not operated for a predetermined time or more. If the configuration allows the user to exit from the self-diagnosis mode, the user can easily exit from the self-diagnosis mode.

  In the in-vehicle remote control device of the present invention, when the self-diagnosis mode is set, the reaction force applying unit is set based on the reaction force pattern set in association with each of a plurality of failure contents assumed in the operation input unit. Is controlled.

  For this reason, for example, even when the communication means fails or when communication via the communication means fails, the operation is performed by changing the reaction force pattern by the reaction force applying unit regardless of the communication system. The failure of the input unit can be diagnosed.

In-vehicle remote control apparatus of the present invention, the operation input unit, one-dimensional, that is configured to include an operation knob which operates within the operating range of the two-dimensional or three-dimensional. The reaction force pattern is a reaction force region that applies an operation reaction force to the operation knob only in a predetermined operation region within the movable range of the operation knob. The reaction force region includes a plurality of failure contents. corresponding manner, the number of formed is set to a different value.

  According to this, when the operation knob is operated in a state where the self-diagnosis mode is set, the failure content can be perceived by the number of reaction force regions formed, and the failure state of the operation input unit can be confirmed.

The operation input unit includes a switch that is turned on by a push-down operation to execute a predetermined function, and the reaction force pattern is applicable when the operation input unit corresponds to two or more of a plurality of failure contents. It includes a switching button function area that functions as a switching button for transitioning the reaction force pattern from one reaction force pattern corresponding to one failure content to another reaction force pattern corresponding to the other failure content. The control unit is configured to transition the reaction force pattern from one reaction force pattern to the other reaction force pattern by detecting the depression of the switch while the operation knob is positioned on the switching button function area. Oh Ru.

  According to this, in addition to the reaction force area, when there are two or more failure contents, there is a switching button function area for transitioning the reaction force pattern from one reaction force pattern corresponding to the failure contents to another reaction force pattern. It is formed. For this reason, it is not necessary to form reaction force patterns corresponding to each of a plurality of failure contents in the movable range of the operation knob at the same time, so that it is possible to reduce misdiagnosis when checking the failure contents.

The operation input unit includes a switch that is turned on by a push-down operation to execute a predetermined function, and when the operation input unit corresponds to two or more of a plurality of failure contents, the control unit by detecting the depressed or as shifting the other reaction force pattern to reaction force pattern corresponding to the other fault condition appropriate from the reaction force pattern corresponding to one of the fault condition applicable.

  According to this, the operation input unit is provided with a switch for transitioning the reaction force pattern from one reaction force pattern corresponding to the failure content to another reaction force pattern when there are two or more failure details. For this reason, it is not necessary to simultaneously form reaction force patterns corresponding to each of a plurality of failure contents within the movable range of the operation knob, as in the case where the switching button function area is formed. Diagnosis can be reduced.

In addition, the operation input unit includes a switch that is turned on by a push-down operation to execute a predetermined function, the failure content is assigned to one of the classified categories, and the reaction force pattern is one of the categories It includes a selection button function area that functions as a selection button that changes the reaction force pattern from one reaction force pattern that can be selected to another reaction force pattern that corresponds to the failure content assigned to the selected category The control unit detects the depression of the switch while the operation knob is positioned on the selection button function area, thereby causing the reaction force pattern to transition from one reaction force pattern to another reaction force pattern. It is good.

  According to this, the selection button function that transitions the reaction force pattern from one reaction force pattern capable of selecting any of the classifications to another reaction force pattern corresponding to the failure content assigned to the selected classification A region is formed. This also eliminates the need to simultaneously form reaction force patterns corresponding to each of a plurality of failure contents within the movable range of the operation knob, thereby reducing misdiagnosis when confirming the failure contents.

a. First Embodiment Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an overall view schematically showing an in-vehicle remote control device 1 according to a first embodiment of the present invention. This in-vehicle remote control device 1 is intended for operation of one or more in-vehicle electronic devices such as a navigation device, an air conditioner device, and an audio device installed in the vehicle, and an operation input unit for inputting operation to each device. 10 and a control unit 20.

  The operation input unit 10 is configured as a pointing device, and performs a position instruction operation on a two-dimensional operation surface with a predetermined operation range. As shown in FIGS. 1 and 2, the operation input unit 10 is connected to the center console CC in the vicinity of the palm of the left hand (right hand in the case of a left-hand drive vehicle) placed naturally so that the driver D can easily operate. The input unit main body 11, the case body 12 covering the upper side of the input unit main body 11, and the exposed form so that the user can directly touch and operate at the opening 12b of the case body 12 are arranged. The operation knob 13 is provided.

  As schematically shown in FIG. 3, the input unit body 11 is provided with electric motors 31 and 32 as reaction force application units that apply an operation reaction force to the operation of the operation knob 13. The electric motors 31 and 32 are provided corresponding to the orthogonal X-axis and Y-axis, respectively, and are connected to the support 13a of the operation knob 13 via gear mechanisms 31a and 32a. The motion is converted into a linear motion along the axial direction (X-axis direction, Y-axis direction) and transmitted to the support 13a of the operation knob 13. That is, the electric motors 31 and 32 operate based on the drive signal from the control unit 20 so as to apply a reaction force against the operation direction to the operation knob 13.

  The operation knob 13 has a two-dimensional operation degree of freedom, and is provided with code plates 33 and 34 and photo interrupters 35 and 36 as position detection mechanisms for detecting a two-dimensional operation input displacement by the operation knob 13. The code plates 33 and 34 are disk-shaped having radial slit rows, and are fixed to the rotating shafts of the electric motors 31 and 32, respectively. Photointerrupters 35 and 36 (encoder modules and position sensors) are composed of signal diodes arranged opposite to each other with code plates 33 and 34 interposed therebetween, and photo ICs including photodiodes, preamplifiers, comparators, and output buffers. ing. The position detection information detected by the photo interrupters 35 and 36, that is, the rotation amount and the rotation direction of the code plates 33 and 34 that change corresponding to the position of the operation knob 13, is fed back to the control unit 20.

  Here, the two-dimensional operation input displacement by the operation knob 13 is set to take coordinate values of 0 to 255 in the X-axis direction and the Y-axis direction, respectively, as shown in FIG. Therefore, if the operation knob 13 is moved to the lower left position, for example, the coordinate value (X, Y) of the operation knob 13 becomes (X, Y) = (0, 0), and the operation knob 13 is moved to the upper right position, for example. When moved, position information is sent to the control unit 20 such that the coordinate value (X, Y) of the operation knob 13 is (X, Y) = (255, 255).

  Returning to FIG. 2, the control contents (for example, command) in various external devices 50 (see FIG. 3) displayed on the display 40 (see FIG. 1, FIG. 3) on the front side of the operation knob 13 of the case body 12. There are provided push-down switches 14 and 15 and a seesaw switch 16 for changing a menu item representing a switch). Further, on both sides of the case body 12, push-down type switches 17 for determining control contents in various external devices 50 are provided. Among these, the switches 14 and 15 incorporate switch illumination LEDs 14a and 15a so that the switch names can be distinguished at night.

  Returning to FIG. 3, the control unit 20 includes a CPU 21 a, a storage unit such as a ROM 21 b and a RAM 21 c, and a memory 21 d made of, for example, a non-volatile memory, and is turned on by turning on an IG switch (not shown) or an ACC switch. Current is supplied from PS.

  The CPU 21a includes input circuits 22a to 22d that receive signal inputs from the switches 14 to 17, input circuits 23 and 24 that receive signal inputs from the operation input unit 10, and X and X that output drive signals to the electric motors 31 and 32, respectively. The Y drive circuits 25 and 26 are connected to a drive circuit 27 that outputs a drive signal to the switch illumination LEDs 14a and 15a.

  Drive signals output from the X and Y drive circuits 25 and 26 to the electric motors 31 and 32, respectively, are input to the CPU 21a via the feedback circuits 25a and 26a, respectively, and stored in the RAM 21c. The CPU 21a executes each program of FIGS. 6 to 12 stored in the ROM 21b using the RAM 21c as a work area. The control unit 20 includes a known watchdog function circuit (not shown) that detects a supply voltage value from the power supply PS. The voltage value detected by the watchdog function circuit is stored in the RAM 21c.

  The control unit 20 is connected to the communication bus BUS for constructing the in-vehicle LAN via the communication circuit 28, and can communicate with the display device 40 (for example, also used as a monitor of the navigation device) and various external devices 50. It is said that. Then, the control unit 20 transmits the position information of the operation knob 13 in the operation input unit 10 and the switch information of the switches 14 to 17 to the display device 40.

  In response to this, the display 40 moves the pointer on the screen so as to be interlocked with the operation of the operation knob 13, and switches the screen so as to be interlocked with the operation of each of the switches 14-17. At this time, the control unit 20 receives reaction force information to be applied to the operation knob 13 from the display 40 in accordance with command information (screen information) displayed on the display 40, output instruction information, and the like.

  Specifically, for example, as shown in FIG. 5A, when menu buttons A to E as control contents are displayed on the screen 41 of the display device 40, the screen corresponds to the operation position of the operation knob 13. The pointer PO on 41 moves. FIG. 5A shows that the operation knob 13 is in a position corresponding to the menu button B. In this state, for example, when the operation knob 13 is swung left and right, the pointer PO moves to the menu button A side or the menu button C side with respect to the menu button B.

  In this case, for example, as shown in FIG. 5B, when the pointer PO enters the menu buttons A to E, a reaction force RF that pulls the pointer PO into the center position of each menu button A to E is operated. 13 is set according to the menu contents (reaction force data is stored in, for example, the ROM 21b). That is, the reaction force RF applied to the operation knob 13 is greatest when the pointer PO is at the end of each menu button A to E, and gradually decreases as it approaches the center of each menu button A to E.

  Thereby, it becomes easy to operate the operation knob 13 in the direction in which the pointer PO approaches the center of each menu button A to E. That is, reaction force information corresponding to the display content of the display 40 is transmitted from the display 40 to the control unit 20, and the control unit 20 controls the torque of the electric motors 31 and 32 according to the reaction force information. The user perceives the reaction force.

  Next, specific processing executed by the in-vehicle remote control device 1 will be described with reference to the flowcharts of FIGS. 6 to 12 are stored in the ROM 21b of the control unit 20, and the CPU 21a of the control unit 20 is configured to be repeatedly executed at the time of activation.

  FIG. 6 is a flowchart showing the main process. The CPU 21a of the control unit 20 performs an initialization process at the time of startup (S11), and determines whether or not the self-diagnostic mode (diag mode) transition condition is satisfied on condition that the ACC switch is turned on (S12: Yes) ( S13).

Here, a specific aspect of the transition condition in the self-diagnosis mode is illustrated.
(1) When the predetermined one of the switches 14 to 16 is pressed when the ACC switch is turned on, or when the predetermined two of the switches 14 to 16 are pressed at the same time, the self-diagnosis mode is entered (S13: Yes). ). In this case, when selecting the switches 14 to 16, it is necessary that the combination of switches to be simultaneously pressed is not used for other purposes.

(2) When a predetermined two of the switches 14 to 16 are pressed in a predetermined order when the ACC switch is turned on, a transition is made to the self-diagnosis mode (S13: Yes). Even in this case, when selecting the switches 14 to 16, it is necessary that the combination of the switches to be continuously pressed is not used for other purposes.

  If the self-diagnosis mode transition condition is not met (S13: No), the normal process defined in steps 14 to 18 is executed. FIG. 7 is a flowchart showing the operation knob input process activated in step S14 of the main process. In this operation knob input process, the indicated position on the two-dimensional operation surface by the operation knob 13 is detected, and the indicated position is stored in the memory 21d (S31). The difference between the designated position and the previous designated position is calculated, and the displacement amount of the designated position is calculated (S32). Based on the calculated displacement amount, the current position coordinates are calculated (converted to 0 to 255) (S33).

  Returning to the main process, the switch input process is executed after the process of step 14 (S15). FIG. 8 is a flowchart showing the switch input process activated in step S15 of the main process. In this switch input process, the CPU 21a of the control unit 20 determines whether any of the switches 14 to 17 in the operation input unit 10 is pressed (S41). When any one of the switches 14 to 17 is pressed down (S41: Yes), the pressed state of the switch is stored in the RAM 21c (S42).

  Returning to the main process of FIG. 6, after the process of step 15, the switch illumination LED output process is executed (S16). FIG. 9 is a flowchart showing the switch illumination LED output process activated in step S16 of the main process. In this switch illumination LED output process, it is confirmed whether the ILL switch is on (S51), and only when it is on (S51: Yes), the switch illumination LEDs 14a and 15a are turned on (S52). Specifically, the CPU 21a of the control unit 20 controls the drive circuit 27 to light both the switch illumination LEDs 14a and 15a.

  Returning to the main process of FIG. 6, after the process of step 16, a communication control process is executed (S17). FIG. 10 is a flowchart showing the communication control process activated in step S17 of the main process. In this communication control process, first, reaction force information transmitted from the display 40 is received (S61). Next, the CPU 21a of the control unit 20 determines whether the operation state has changed in the operation knob input process in step S14 or the switch input process in step S15 (S62). If the operation state has changed (S62: Yes), the changed operation knob input information and switch input information are transmitted to the display 40 (S63).

  Returning to the main process of FIG. 6, after the process of step 17, the reaction force output process for the normal process is executed (S18). Here, based on the reaction force information received in step 17 and the displacement amount of the indicated position detected in the operation knob input process in step 14, the current value to be passed through the X and Y drive circuits 25 and 26 is determined and output. Thereby, when the operation knob 13 is operated, an operation feeling (reaction force) linked to the screen information displayed on the display 40 can be obtained.

  By repeatedly executing the normal processing of steps S14 to S18, the pointer PO moves on the screen 41 of the display 40 corresponding to the operation position of the operation knob 13 while the operation reaction force is applied to the operation knob 13. It becomes like this.

  On the other hand, when the self-diagnosis mode transition condition is met (S13: Yes), the self-diagnosis process (diagnosis process) defined in steps S19 and S20 is executed. FIG. 11 is a flowchart showing the internal failure detection process activated in step S19 of the main process.

  In this internal failure detection process, the CPU 21a of the control unit 20 receives the input signals of the input circuits 23 and 24 when the operation knob 13 is operated and the drive signals of the feedback circuits 25a and 26a in the X and Y drive circuits 25 and 26. To detect. Further, the input signals of the input circuits 22a to 22d when the switches 14 to 17 are turned on are detected.

  Further, the sum check result of the CPU 21a, the voltage state of the power source PS by the watchdog function circuit, and the cell check results of the RAM 21c, memory 21d, etc. are acquired (S71). From these results and the like, it is possible to determine an abnormality in the CPU 21a, power supply PS, RAM 21c, memory 21d, and the like. In the following description, it is assumed that the CPU 21a, power supply PS, RAM 21c, memory 21d, etc. are normal.

  It is determined whether or not there is an abnormal part based on the input signal or the like detected in step S71 (S72). When there is an abnormal part (S72: Yes), a diagnostic code corresponding to the abnormal part is set with reference to the diagnostic determination table stored in the ROM 21b (S73).

  FIG. 13 is a schematic diagram illustrating an example of a diagnosis determination table. As described above, the diagnosis determination table stores the failure content assumed in the operation input unit 10 and the diagnosis code in association with each other. In this example, disconnection or short circuit of the photo interrupters 35 and 36 is determined based on the input signals of the input circuits 23 and 24 when the operation knob 13 is operated. To "". Further, the disconnection or short circuit of the switches 14 to 17 is determined based on the input signals of the input circuits 22a to 22d when the switches 14 to 17 are operated. If the disconnection or the short circuit is determined, the diagnosis code is set to “2”. Set.

  Also, the operation signals of the X and Y drive circuits 25 and 26 are checked by comparing the drive signals to the X and Y drive circuits 25 and 26 when the operation knob 13 is operated with the drive signals of the feedback circuits 25a and 26a. When the malfunction of the X or Y drive circuits 25 and 26 is determined, the diagnosis code is set to “3”.

  Further, when it is determined that all of the input circuits 23, 24, X and Y drive circuits 25, 26 are normal, the input signals of the input circuits 23, 24 and the drive signals to the X and Y drive circuits 25, 26 are displayed. Based on the above, the operation state of the electric motors 31 and 32 is checked, and if the operation failure of the electric motors 31 and 32 is determined, the diagnosis code is set to “4”.

  Returning to the main process of FIG. 6, after the process of step 19, a reaction force output process for diagnosis process is executed (S20). FIG. 12 is a flowchart showing the reaction force output process for diagnosis process started in step S20 of the main process. In the reaction force output process for diag processing, the CPU 21a of the control unit 20 drives the electric motors 31 and 32 so that a reaction force corresponding to the diag code is generated with reference to the reaction force pattern table stored in the ROM 21b. That is, the value of the current passed through the X and Y drive circuits 25 and 26 is determined and output (S81). When it is determined that either one of the electric motors 31 and 32 is malfunctioning, the normal one is driven.

  FIG. 14 is a schematic diagram illustrating an example of a reaction force pattern table. Thus, the reaction force pattern table stores the diagnosis code and the reaction force pattern applied to the operation knob 13 in association with each other. FIG. 15 is a schematic diagram showing an example of a reaction force pattern applied to the operation knob 13 in accordance with the reaction force pattern table of FIG. Specifically, when the diagnosis code is “1” (disconnection or short circuit of the photo interrupters 35 and 36), the reaction force is applied to the operation knob 13 with only the first operation region R1 in the knob movable range R as the reaction force region. Is given (FIG. 15A). That is, a reaction force RF that pulls the operation knob 13 to the center position of the first operation region R1 is obtained only when the operation knob 13 is positioned on the first operation region R1.

  Similarly, when the diagnosis code is “2” (disconnection or short of the switches 14 to 17), the first operation region R1 and the second operation region R2 of the knob movable range R are set as reaction force regions (FIG. 15B). )), When the diagnosis code is “3” (operation failure of the X or Y drive circuits 25, 26), the first operation region R1, the second operation region R2, and the third operation region R3 of the knob movable range R are set. When the reaction force region is set (FIG. 15 (c)) and the diagnosis code is “4” (operation failure of the electric motors 31 and 32), the first operation region R1, the second operation region R2, and the second operation region R2, With the third operation region R3 and the fourth operation region R4 as reaction force regions (FIG. 15 (d)), a reaction force RF is applied to the operation knob 13, respectively.

  In other words, the reaction force region is set to a different value for the number of formations so as to correspond to the failure content (in the example of FIG. 15, the number of formations is set to 1 to 4). Thereby, the failure content can be perceived by the number of reaction force regions formed in the knob movable range R, and the failure state of the operation input unit 10 can be confirmed.

  Returning to the main process of FIG. 6, when the ACC switch is turned off while the self-diagnosis process (steps S19 and S20) is being executed, it is possible to exit from the self-diagnosis mode (S12: No). In this case, the pre-end processing is performed (S21), and then the program execution is ended. Note that the method of exiting the self-diagnosis mode is not limited to turning off the ACC switch. For example, when the control unit 20 is reset in addition to or in place of turning off the ACC switch, or for the operation knob 13 and the switches 14 to 17. It may be when the operation is not performed for a predetermined time or longer (determined by timer mounting).

  As is clear from the above description, according to the first embodiment, when the self-diagnosis mode is set (S12: Yes, S13: Yes in FIG. 6), a plurality of assumptions are made in the operation input unit 10. The electric motors 31 and 32 (reaction force applying unit) are controlled based on the reaction force pattern set in association with each failure content (steps S19 and S20).

  Thus, for example, even when the communication circuit 28 fails or when communication via the communication circuit 28 fails, the reaction force pattern of the electric motors 31 and 32 is independent of the communication system. The failure of the operation input unit 10 can be diagnosed by the change.

b. Second Embodiment In the first embodiment, the case where one of the plurality of failure contents corresponds to one of the failure contents has been described. However, the diagnosis code corresponds to two or more of the plurality of failure contents. When a plurality of reaction forces are set, the reaction force pattern can be changed from a reaction force pattern corresponding to one of the failure contents to a reaction force pattern corresponding to the other of the failure contents. Other configurations are the same as those in the first embodiment.

  FIG. 16 illustrates a transition mode between the reaction force patterns when, for example, “1”, “2”, and “4” are set among the diagnosis codes “1” to “4”. In this case, first, the first operation region R1 in the knob movable range R is set as the reaction force region corresponding to the diagnosis code “1”. In the second embodiment, in addition to the first operation area R1, the switching button function area R11 is set as a reaction force area. The switching button function area R11 is formed at the lower right corner of the knob movable area R, for example, and changes the reaction force pattern from the reaction force pattern corresponding to the diagnosis code “1” to the reaction force pattern corresponding to the diagnosis code “2”. Functions as a switch button for sending (sending later). By forming the switching button function region R11, it can be perceived that another diag code different from the diag code “1” is set.

  In a state where the operation knob 13 is positioned on the switching button function region R11, a reaction force RF that pulls the operation knob 13 to the center position of the switching button function region R11 is obtained. If any one of the switches 14 to 17 is depressed in this state, the reaction force pattern corresponding to the diagnosis code “1” is changed to the reaction force pattern corresponding to the diagnosis code “2” as shown by a broken line T2 in the drawing. Transition.

  In the reaction force pattern corresponding to the diagnosis code “2”, the switching button function regions R21 and R22 are set as the reaction force region in addition to the first operation region R1 and the second operation region R2. The switching button function area R21 is formed at the lower right corner of the knob movable area R, for example, as in the switching button function area R11, and the reaction force corresponding to the diagnosis code “4” from the reaction force pattern corresponding to the diagnosis code “2”. It functions as a switch button that changes the reaction force pattern to the pattern (sends it later). By forming the switching button function region R21, it can be perceived that another diag code different from the diag codes “1” and “2” is set.

  On the other hand, the switching button function area R22 is formed, for example, in the lower left corner of the knob movable area R, and changes from a reaction force pattern corresponding to the diagnosis code “2” to a reaction force pattern corresponding to the diagnosis code “1”. It functions as a switching button for transitioning (returning to the front) the reaction force pattern.

  Accordingly, when any of the switches 14 to 17 is depressed while the operation knob 13 is positioned on the switching button function area R21, the reaction force corresponding to the diagnosis code “2” as shown by the broken line T4 in the figure. Transition from the pattern to the reaction force pattern corresponding to the diagnosis code “4”. On the other hand, when one of the switches 14 to 17 is depressed while the operation knob 13 is positioned on the switching button function region R22, the reaction force corresponding to the diagnosis code “2” as indicated by the broken line T1 in the figure. Transition from the pattern to the reaction force pattern corresponding to the diagnosis code “1”.

  In the reaction force pattern corresponding to the diagnosis code “4”, the switching button function region R42 is added to the reaction force region in addition to the first operation region R1, the second operation region R2, the third operation region R3, and the fourth operation region R4. Is set. Similar to the switch button function area R22, the switch button function area R42 is formed, for example, in the lower left corner of the knob movable area R, and the reaction force pattern corresponding to the diagnosis code “4” from the reaction force pattern corresponding to the diagnosis code “4”. It functions as a switch button that changes the reaction force pattern to the pattern (returns to the previous).

  Therefore, when one of the switches 14 to 17 is depressed while the operation knob 13 is positioned on the switching button function area R42, the reaction force corresponding to the diagnosis code “4” as shown by the broken line T2 in the figure. A transition is made from the pattern to the reaction force pattern corresponding to the diagnosis code “2”. Since no area corresponding to the switching button function area R21 is formed, it can be perceived that no diag code other than the diag codes “1”, “2”, and “4” is set.

  According to the second embodiment, it is not necessary to simultaneously form reaction force patterns corresponding to each of a plurality of failure contents in the knob movable range R, so that it is possible to reduce misdiagnosis when checking the failure contents.

(Modification)
In the second embodiment, the reaction force pattern is changed by pressing one of the switches 14 to 17 while the operation knob 13 is positioned on the switching button function area R11, R21, R22, R42. Instead of forming the switching button function areas R11, R21, R22, and R42, the reaction force pattern may be changed only by pressing one of the switches 14 to 17. This modification can also reduce misdiagnosis at the time of confirming the failure content.

c. Third Embodiment In the first and second embodiments described above, operation input units such as disconnection or short circuit of the photo interrupters 35 and 36 and the switches 14 to 17, malfunction of the X or Y drive circuits 25 and 26 and the electric motors 31 and 32, etc. However, in addition to this operation input system, it is also possible to perform a failure diagnosis of a communication system including the communication circuit 28.

  The communication circuit 28 sets a fail flag to “0” when communication is normal, and sets a fail flag to “1” when communication is abnormal (for example, malfunction of the communication circuit 28, communication failure, etc.). A setting circuit 28a is provided (see FIG. 1). The set fail flag is stored in the RAM 21c, and is read by the CPU 21a of the control unit 20 when the internal failure detection process is executed. Other configurations are the same as those in the first embodiment.

  FIG. 17 is a schematic diagram illustrating an example of a hierarchical structure in which diag codes are classified into operation input systems and communication systems, and diag codes are assigned to the respective classes. In this example, diagnosis codes “1” to “4” are assigned to the operation input system, and diagnosis codes “1” and “2” are assigned to the communication system.

  FIG. 18 shows a transition mode between the reaction force patterns when the operation input type diag code is set to “3” and the communication type diag code is set to “2”, for example. In this case, a selection button function area RD (operation input system button function area) and RT (communication system button function area) capable of selecting one of the classifications first are set as reaction force areas. The selection button function areas RD and RT are formed, for example, on the left and right of the center part of the knob movable area R, and the reaction force pattern is shifted to the reaction force pattern corresponding to the diag code assigned to each classification (from the first layer to the first layer). Functions as a selection button.

  In a state where the operation knob 13 is positioned on the selection button function region RD or RT, a reaction force RF that pulls the operation knob 13 to the center position of the selection button function region RD or RT is obtained. When one of the switches 14 to 17 is depressed with the operation knob 13 positioned on the selection button function area RD, the selection button function areas RD and RT are formed as shown by the broken line T01 in the figure. A transition is made from the force pattern to the reaction force pattern corresponding to the diag code “3” of the operation input system. When one of the switches 14 to 17 is depressed while the reaction force pattern corresponding to the diagnosis code “3” is formed, the selection button function areas RD and RT are formed as shown by the broken line T10 in the figure. Return to the reaction force pattern.

  On the other hand, when one of the switches 14 to 17 is depressed while the operation knob 13 is positioned on the selection button function area RT, selection button function areas RD and RT are formed as shown by a broken line T02 in the figure. The reaction force pattern transitions to the reaction force pattern corresponding to the communication system diagnosis code “2”. When one of the switches 14 to 17 is depressed in a state where the reaction force pattern corresponding to the diagnosis code “2” is formed, the selection button function areas RD and RT are formed as indicated by the broken line T20 in the figure. Return to the reaction force pattern.

  When a plurality of diagnosis codes are assigned to each classification, a switching button function area for making a transition from one reaction force pattern to another reaction force pattern may be formed as in the second embodiment. Is possible.

  Also in the third embodiment, as in the second embodiment, it is not necessary to simultaneously form reaction force patterns corresponding to each of a plurality of failure contents in the knob movable range R. Diagnosis can be reduced.

  In the first to third embodiments, the reaction force RF applied to the operation knob 13 in each reaction force region is greatest when it is at the end of each region, and gradually decreases as it approaches the center of each region. For example, a resistance force perceived as a force of a predetermined magnitude or more may be applied to the operation knob 13.

  Moreover, in the said 1st-3rd embodiment, although this invention was applied to the operation input part 10 of the aspect in which the operation knob 13 operate | moves on a two-dimensional operation surface, for example, FIG. 19, FIG. 20 or FIG. As shown specifically, the present invention may be applied to the operation input unit 10 in a mode in which the operation knob 13 operates in a one-dimensional operation direction (front and rear, left and right, and around the axis). For example, as schematically shown in FIG. 22, the present invention can be applied to the operation input unit 10 in a mode in which the operation knob 13 operates in a three-dimensional operation direction (X direction, Y direction, Z direction). It is. In the example of FIG. 22, the support column 13a of the operation knob 13 is movable in the vertical direction (Z direction), and the vertical displacement of the support column 13a is detected by the position sensor. Also in the modified examples shown in FIGS. 19 to 22, when the operation knob 13 is operated, the failure content can be perceived by the number of reaction force regions formed, and the failure state of the operation input unit 10 can be confirmed.
