(First embodiment)
The configuration of the in-vehicle display system according to the first embodiment of the present invention is shown in FIG. This in-vehicle display system functions as an in-vehicle navigation system. The in-vehicle display system includes an operation device 10 and a display control device 20, and the operation device 10 is installed on a center console of a vehicle, and the display control device 20 is installed on an instrument panel of the vehicle.

  The operation device 10 includes an operation unit 11 and a drive unit 12. A schematic configuration of the operation unit 11 is shown in FIG. (A) is a plan view of the operation unit 11, and (b) is a side view of the upper part of the operation unit 11.

  The operation part 11 has a substantially hemispherical holder part 11c having a substantially circular opening 11b formed at the top, and a hemispherical operation knob 11a housed inside the holder part 11c. The operation knob 11a is configured to rotate on the operation surface in the X axis-Y axis direction in accordance with a user operation. The operation unit 11 has a detection circuit (not shown) for detecting the position of the operation knob 11a, and the position (X coordinate, Y coordinate) of the operation knob 11a is expressed as an absolute value from the detection circuit. A position signal is sent to the display control device 20.

  The operation device 10 is configured as a so-called haptic controller that applies a reaction force such as a reaction force or a thrust to the operation knob 11a according to an operation state.

  The drive unit 12 includes a plurality of actuators that apply a reaction force to the operation knob 11a and an actuator (none of which is shown) that generates vibrations on the operation knob 11a, and each actuator according to an instruction from the control unit 23. Is driven, a reaction force is applied to the operation knob 11a in an arbitrary direction, and vibration is generated in the operation knob 11a. By applying a reaction force in the direction opposite to the user's operation direction to the operation knob 11a, the operation load of the operation knob 11a is increased, and a reaction force in the same direction as the user's operation direction is applied to the operation knob 11a. It becomes possible to lighten the operation load of the operation knob 11a.

  The display control device 20 includes a storage unit 21, a display unit 22, and a control unit 23.

  The storage unit 21 has a nonvolatile storage medium such as a hard disk drive, and stores various data in the nonvolatile storage medium. The storage unit 21 stores a program executed by the control unit 23, map data for map display and route search, a reaction force map described later, and the like.

  The display unit 22 displays various display screens according to the display data input from the control unit 23.

  The control part 23 is comprised as a computer provided with CPU, memory, I / O, etc., CPU implements various processes according to the program memorize | stored in memory.

  As processing of the control unit 23, various display screens are displayed on the display unit 22, and a display unit is selected so that a cursor for selecting a selection button displayed on the display screen so as to be selectable is interlocked with the position of the operation knob. There is a process to be displayed.

  In the storage unit 21 in the present embodiment, display data for displaying various display screens such as a map display screen, a search processing screen, an air conditioner setting screen, an audio setting screen, and a navigation screen is used for identifying each display screen. It is stored in association with the screen ID.

  Furthermore, in the storage unit 21 in the present embodiment, a display screen including a scroll display area in which a plurality of selection buttons are scroll-displayed in association with the screen ID of each display screen displayed on the display unit 22 is displayed. When the cursor is positioned on the first selection button or the last selection button among the multiple selection buttons, the control knob vibrates and the cursor moves between the multiple selection buttons displayed in the scroll display area. When moving, a reaction force is generated in the operation knob so that the cursor stays on the selection button before the movement, and when the cursor moves in one direction between the selection buttons, the reaction force is large. A reaction force map that prescribes the reaction force applied to the operation knob so that the height changes stepwise is stored.

  The control unit 23 acquires a reaction force map corresponding to the display screen to be displayed on the display unit 22 from the storage unit 21, and generates vibration and reaction generated on the operation knob 11a based on the acquired reaction force map and the display position of the cursor. A process of instructing the drive unit 12 to determine the force and generate the determined vibration and reaction in the operation knob is performed.

  Here, the reaction force map will be described with reference to FIG. FIG. 3 shows a display screen including a scroll display area in which a plurality of selection buttons are scrollably displayed. In the figure, only the selection buttons B08 to B10, B01, and B02 are displayed, but the selection buttons B01 to B10 can be displayed by a scroll operation. Note that the selection buttons B08 to B10, B01, and B02 displayed in the scroll display area are actually displayed in numerical order, alphabetical order, alphabetical order, and alphabetical order as numerals, Japanese alphabets, and alphabets. The selection button B01 indicates the first selection button, and the selection button B10 indicates the last selection button. This figure also shows a state where the cursor K is positioned on the selection button B10. Further, on the left side of the map display screen, reaction force setting values (hereinafter referred to as Y coordinate reaction force setting values) of respective parts on the line BB in the map display screen are shown.

  Here, the reaction force setting value on the Y-axis side is + (plus) for the force acting downward,-(minus) force for the upward movement, and the reaction force setting value on the X-axis side is the force acting on the right side + (Plus), the force acting on the left side is-(minus). The reaction force is such that each of the above forces works toward the center of the button. Therefore, the Y coordinate reaction force setting value F (y) is a positive value (plus) in the upper half on each of the selection buttons B08 to B10, B01, B02 displayed on the map display screen. The lower half on B08 to B10, B01, and B02 is a negative value (minus), and the central portion on each of the selection buttons B08 to B10, B01, and B02 is 0. This is because when the cursor K is moved from the selection buttons B08 to B10, B01, B02 to the upper selection button, the cursor K is moved downward (−Y direction), that is, the operation knob 11a is moved forward. When a reaction force is generated in the direction to move the cursor K and the cursor K is moved from the selection button B08 to B10, B01, B02 to the selection button on the lower side, the cursor K is moved upward (Y direction). This means that a reaction force is generated in the direction in which the operation knob 11a is moved forward. That is, when the cursor K moves between the selection buttons, it means that a reaction force is generated on the operation knob 11a so that the cursor K stays on the selection button before the movement. The Y coordinate reaction force setting value F (y) is smallest on the selection button B01, gradually increases from the selection button B01 to the selection button B10, and is largest on the selection button B10. It has become. This means that when the cursor K moves in ascending order between a plurality of selection buttons, a reaction force is applied to the operation knob 11a so that the magnitude of the reaction force increases stepwise.

  Further, FIG. 3 shows a vibration mark V instructing to vibrate the operation knob 11a at a position corresponding to the last selection button B10. This means that the reaction force map defines that the operation knob 11a is vibrated when the cursor K is positioned on the last selection button B10.

  The reaction force map as described above is stored in the storage unit 22 in association with the screen ID of each display screen displayed on the display unit 21.

  The control unit 23 determines the vibration and reaction force to be generated in the operation knob 11a based on the reaction force map and the display position of the cursor K, and the drive unit to generate the determined vibration and reaction force in the operation knob 11a. The process instructed to is performed.

  In the in-vehicle display system according to the present embodiment, when a display screen including a scroll display area in which a plurality of selection buttons are scrollably displayed is displayed on the display unit 22, vibration is applied to the operation knob 11 a and the selection buttons are displayed. A process of notifying the user that the circuit has been completed and giving a reaction force to the operation knob 11a to inform the user in which direction the plurality of selection buttons are operated is performed.

  Next, the process of the control part 23 is demonstrated according to FIG. The vehicle-mounted display system is in an operating state when the ignition switch of the vehicle is turned on, and the control unit 23 performs the process shown in FIG. 4 together with the process of displaying various display screens on the display unit 22 and the like.

  First, the screen ID of the display screen displayed on the display unit 22 is specified (S100). In the present embodiment, the display screen shown in FIG. 3 is displayed on the display unit 22, and the screen ID associated with the display screen is read from the storage unit 21 and specified.

  Next, a reaction force map corresponding to the screen ID is acquired (S102). Specifically, a reaction force map corresponding to the screen ID is acquired from the storage unit 21. As shown in the Y coordinate reaction force setting value in FIG. 3, the reaction force map includes a cursor K on the last selection button B10 displayed in the display area in which a plurality of selection buttons are scrollably displayed. When there is a display position, vibration is generated in the operation knob 11a, and when the cursor K moves between a plurality of selection buttons displayed in the scroll display area, the cursor K is placed on the selection button before the movement. A reaction force is generated on the operation knob so as to stay, and when the cursor K moves in one direction between a plurality of selection buttons, the reaction knob is applied to the operation knob so that the magnitude of the reaction force changes stepwise. Reaction force is prescribed.

  Next, a position signal indicating the position of the operation knob 11a is acquired from the operation device 10 (S104).

  Next, the vibration and reaction force generated in the operation knob 11a are determined (S106). Specifically, the display position of the cursor K to be displayed on the display screen is determined based on the position signal indicating the position of the operation knob 11a, and the direction of vibration and reaction force generated in the operation knob 11a based on the reaction force map. And determine the size.

  Next, the drive unit 12 is instructed to generate the determined vibration and reaction force (S108), and the process returns to S100. Thereby, the vibration and reaction force according to the display position of the cursor K are given to the operation knob 11a. Note that the user can move the cursor K onto a desired selection button by operating the operation knob 11a with a force larger than the reaction force applied to the operation knob 11a. Further, the greater the reaction force applied to the operation knob 11a, the heavier the operation load of the operation knob 11a, and the smaller the reaction force applied to the operation knob 11a, the lighter the operation load of the operation knob 11a is felt.

  Therefore, when the operation knob 11a is operated so that the display position of the cursor K is on the selection button B08, the selection button B09, and the selection button B10, the magnitude of the reaction force applied to the operation knob 11a is stepwise. It feels like the operation load increases in steps. Then, when the display position of the cursor K is on the top selection button B01, the magnitude of the reaction force applied to the operation knob 11a is minimized, and it is felt that the operation load is suddenly reduced. Further, when the operation knob 11a is operated so that the display position of the cursor K moves on the operation button in ascending order, the magnitude of the reaction force applied to the operation knob 11a increases stepwise, and the operation load gradually increases. It feels like As described above, when the operation knob 11a is operated so that the display position of the cursor K moves in one direction on the selection button, the magnitude of the reaction force applied to the operation knob 11a increases stepwise. Feels like heavier in steps.

  Further, when the display position of the cursor K is on the last selection button B10, the operation knob 11a vibrates, so that the user can easily recognize that the cursor K is located on the last selection button B10.

  According to the configuration described above, the display control device creates a map that specifies that the operation knob generates vibration when the cursor is positioned on the last selection button among the plurality of selection buttons included in the scroll display area. When the cursor is positioned on the last selection button obtained from the storage unit and based on the obtained map, the operation unit 12 is instructed to generate vibration on the operation knob. The position of the cursor can be recognized by the vibration of the operation knob, and the time for gazing at the display screen during the selection operation can be shortened.

  Furthermore, since the magnitude of the reaction force applied to the operation knob changes stepwise when the cursor moves in one direction between the plurality of selection buttons, the user can apply the reaction force applied to the operation knob. It is also possible to recognize the movement direction of the cursor from the size of.

  In the present embodiment, a map defining that the operation knob is caused to vibrate when the cursor is positioned on the last selection button B10 among the plurality of selection buttons is stored in the storage unit, and the last selection button Although the configuration in which the operation knob is vibrated when the cursor is positioned on B10 is shown, for example, when the cursor is positioned on the first selection button B01 among the plurality of selection buttons, vibration is generated in the operation knob. May be stored in the storage unit, and the operation knob may be vibrated when the cursor is positioned on the top selection button B01.

(Second Embodiment)
The configuration of the in-vehicle display system according to the present embodiment is the same as that shown in FIG. 1, and the process of the control unit 23 is the same as the process shown in FIG. The in-vehicle display system according to the present embodiment differs from the in-vehicle display system according to the first embodiment in the display screen displayed on the display unit 22 and the reaction force map.

  The vehicle-mounted display system according to the present embodiment has a minimum setting that minimizes the airflow setting value among a series of setting buttons for setting the airflow of the air conditioner when the air conditioner display screen is displayed on the display unit 22. When the cursor is positioned on the button or on the maximum setting button where the airflow setting value is the maximum, the control knob is vibrated, and when the cursor moves between multiple setting buttons, the cursor is not moved. Generate a reaction force on the control knob to stay on the selection button.

  FIG. 5 shows a display example of the air conditioner setting screen. The air conditioner setting screen includes a setting button display area in which a plurality of setting buttons B01 to B07 for setting the air volume of the air conditioner are arranged in a line. Here, the setting button B01 is a minimum setting button, and the setting button B07 is a maximum setting button. In addition, the X coordinate reaction force setting value F (x) of each part on the line AA in the display screen is also shown below the display screen.

  As for the X coordinate reaction force setting value F (x), the left half of each setting button B01 to B07 displayed on the air conditioner setting screen has a negative value (minus), and the right half of each setting button B01 to B07. Is a positive value (plus), and the central portion of each of the setting buttons B01 to B07 is 0. For example, when the cursor K is moved from the setting button B01 to the right selection button B02, the cursor K is moved in the left direction (−X direction), that is, the operation knob 11a is moved in the left direction. When the cursor K is moved from the setting button B02 to the left selection button B01, the direction in which the cursor K is moved in the right direction (X direction), that is, the operation knob 11a is moved to the right. This means that a reaction force is generated in the direction to be generated. That is, when the cursor K moves between the selection buttons, it means that a reaction force is generated on the operation knob 11a so that the cursor K stays on the selection button before the movement. Further, the magnitude of the Y coordinate reaction force setting value F (y) is constant.

  FIG. 5 shows a small vibration mark V1 for instructing to vibrate the operation knob 11a at a position corresponding to the minimum value setting button B01, and an operation knob at a position corresponding to the maximum value setting button B07. A large vibration mark V7 instructing to vibrate 11a is shown. This means that the operation knob 11a is vibrated small when the cursor K is positioned on the minimum value setting button B01, and the operation knob 11a is vibrated greatly when the cursor K is positioned on the maximum value setting button B07. means. In this way, the operation knob 11a is vibrated small when the cursor K is positioned on the minimum value setting button B01, and the operation knob 11a is vibrated greatly when the cursor K is positioned on the maximum value setting button B07. Is defined in the reaction force map.

  Therefore, when the operation knob 11a is operated so that the display position of the cursor K is on the setting button B01, the operation knob 11a vibrates slightly, and the display position of the cursor K is on the setting button B02 and the setting button B03. Each time the operation knob 11a is operated so as to be on the setting button B04, ..., the setting button B06, a reaction force is applied to the operation knob 11a, and a certain operation load is applied to the operation knob 11a. It is done. When the operation knob 11a is operated so that the display position of the cursor K is on the setting button B07, the operation knob 11a vibrates greatly. In this way, when the operation knob 11a is operated so that the display position of the cursor K moves in one direction on the selection button, a reaction force having a certain magnitude is applied to the operation knob 11a. Further, when the cursor K is positioned on the minimum value setting button B01, the operation knob 11a vibrates slightly, and when the cursor K is positioned on the maximum value setting button B07, the operation knob 11a vibrates greatly, so that the user can operate the operation knob 11a. By this vibration, it can be easily recognized that the operation knob 11a is positioned on the minimum value setting button B01 or the maximum value setting button B07.

  According to the configuration described above, the display control device is a setting button in which a plurality of setting buttons including a maximum setting button that maximizes the setting value and a minimum setting button that minimizes the setting value are displayed in a line. For the display screen including the display area, a map that specifies that the operation knob generates vibration when the cursor is positioned on the minimum setting button or the maximum setting button is acquired from the storage unit, and based on the acquired map When the cursor is positioned on the minimum setting button or the maximum setting button, the biasing means is instructed to generate vibration on the operation knob, so that the user has positioned the cursor on the minimum setting button or the maximum setting button. This can be recognized by the vibration of the operation knob, and the time for gazing at the display screen during the selection operation can be shortened.

  Also, the reaction force map stipulates that the vibration generated by the control knob is greater when the cursor is displayed on the maximum setting button than when the cursor is positioned on the minimum setting button. Because the vibration of the control knob is larger when the cursor is displayed on the maximum setting button than when the cursor is positioned on the minimum setting button, the user can set the minimum setting from the magnitude of the vibration of the operation knob. It is possible to recognize whether the cursor is located on the button or on the maximum setting button.

  In addition, when the cursor moves between multiple setting buttons displayed in the setting button display area, a reaction force map is generated on the operation knob so that the cursor stays on the selection button before the movement. When the cursor moves between multiple setting buttons, the reaction force is applied to the operation knob so that the cursor stays on the selection button before the movement. It is also possible to recognize whether or not the cursor has moved over a different selection button due to the reaction force.

  In addition, although this embodiment demonstrated the case where a series of several setting buttons for setting the air volume of the air conditioner contained in an air-conditioner display screen were operated, when operating the setting button contained in such a display screen For example, the present invention may be applied when operating a volume setting button or the like included in the audio display screen.

(Third embodiment)
The configuration of the in-vehicle display system according to the present embodiment is the same as that shown in FIG. 1, and the process of the control unit 23 is the same as the process shown in FIG. The in-vehicle display system according to the present embodiment differs from the in-vehicle display system according to the first and second embodiments in the display screen displayed on the display unit 22 and the reaction force map.

  The vehicle-mounted display system according to the present embodiment vibrates when the cursor moves in one direction between a series of setting buttons for setting the air volume of the air conditioner when the air conditioner display screen is displayed on the display unit 22. Vibration is applied to the control knob so that the size of the control knob changes in stages, and when the cursor moves between multiple setting buttons, the control knob is set so that the cursor stays on the selection button before the movement. Generate reaction force.

  FIG. 6 shows a display example of the air conditioner setting screen. The air conditioner setting screen includes a setting button display area in which a series of a plurality of setting buttons B01 to B07 for setting the air volume of the air conditioner are displayed in a line. In addition, the X coordinate reaction force setting value F (x) of each part on the line AA in the display screen is also shown below the display screen.

  The X coordinate reaction force setting value F (x) is a negative value (minus) in the left half of each of the setting buttons B01 to B07 displayed on the air conditioner setting screen, as in the second embodiment shown in FIG. ), And the right half of each of the setting buttons B01 to B07 has a positive value (plus), and the central portion of each of the setting buttons B01 to B07 is 0. This means that when the cursor K moves between the selection buttons, a reaction force is generated on the operation knob 11a so that the cursor K remains on the selection button before the movement.

  FIG. 6 also shows a small vibration mark V1 for instructing to vibrate the operation knob 11a at a position corresponding to the minimum value setting button B01, and the operation knob at a position corresponding to the maximum value setting button B07. A large vibration mark V7 instructing to vibrate 11a is shown. Further, vibration marks V2 to V6 are shown at positions corresponding to the setting buttons B02 to B06, respectively. Note that the size of each vibration mark gradually increases from the vibration mark V1 to the vibration mark V7. That is, when the cursor K is positioned on the minimum value setting button B01, the operation knob 11a is vibrated smallly, on the setting button B02, on the setting button B03, on the setting button B04,... This means that the vibration of the operation knob 11a gradually increases as the cursor K moves on B07. As described above, when the cursor K is positioned on the setting button B01 for the minimum value, the operation knob 11a is vibrated slightly to set the maximum value on the setting button B02, the setting button B03,..., The setting button B07. The reaction force map stipulates that a large vibration is gradually applied to the operation knob 11a as the cursor K moves on the button B07.

  Therefore, by using such a reaction force map, when the operation knob 11a is operated so that the display position of the cursor K is on the setting button B01, the operation knob 11a vibrates slightly, and the display position of the cursor K is changed. Each time the operation knob 11a is operated so as to be on the setting button B02, the setting button B03,..., The setting button B06, a constant reaction force is applied to the operation knob 11a. The vibration applied to the is increased stepwise. Therefore, as the display position of the cursor K moves on the setting button in ascending order, the vibration applied to the operation knob 11a gradually increases, and the user can change the display position of the cursor K from the vibration applied to the operation knob 11a. It is possible to recognize that the setting button is moved in ascending order.

  According to the configuration described above, the display control device operates so that the magnitude of vibration changes stepwise when the cursor moves in one direction between a series of setting buttons included in the setting button display area. A map that defines the vibration to be applied to the knob is acquired from the storage unit, and when the cursor moves in one direction between a series of setting buttons included in the setting button display area based on the acquired map, Since the drive unit 12 is instructed to generate vibration in the operation knob so that the magnitude changes stepwise, the user can recognize the moving direction of the cursor from the magnitude of the vibration of the operation knob, and select operation Time for gazing at the display screen at the time can be shortened.

  In addition, when the cursor moves between multiple setting buttons displayed in the setting button display area, a reaction force map is generated on the operation knob so that the cursor stays on the selection button before the movement. When the cursor moves between multiple setting buttons, the reaction force is applied to the operation knob so that the cursor stays on the selection button before the movement. It is also possible to recognize whether or not the cursor has moved over a different selection button due to the reaction force.

In addition, when the control unit 23 determines that the event has occurred and determines that the speaker is set to prohibit audio output, the control unit 23 generates vibration in the operation knob 11a instead of audio output. Then, a process for notifying that the event has occurred is performed.

  FIG. 7 shows a flowchart of the control unit 23 according to the present embodiment. The control unit 23 starts the process shown in FIG. 7 when the ignition switch of the vehicle is turned on to enter the operating state.

  First, it is determined whether an event has occurred (S200). Specifically, it is determined whether or not a predetermined event has occurred, such as when recording of music data using the audio function is completed or downloading of various data using the communication function is completed.

  Here, for example, when the recording of the music data using the audio function is completed, the determination in S200 is YES, and then it is determined whether or not the audio output is set to be prohibited (S202).

  Here, if the setting is such that voice output is not prohibited, the fact that an event has occurred is notified by voice (S204). For example, a predetermined sound such as “ping-pong” is output from the speaker, and the process returns to S200.

  In addition, for example, when the sound volume is set to 0, or when the sound output is prohibited, such as when the sound volume is set to mute, the operation unit 11a is vibrated so as to vibrate. 12 is instructed (S206). Therefore, the user can recognize that the event has occurred by sensing the vibration of the operation knob 11a with the hand attached to the operation knob 11a.

  According to the configuration described above, the display control device determines that the event has occurred, and if it is determined that the audio output is set to be prohibited, the drive unit generates vibration on the operation knob. 12 is informed that the event has occurred, so that it can be notified more reliably.
