For example, when the driver H continues to press the left end of the steering wheel side operation unit 6, the frame image I2 displayed on the liquid crystal display unit 40b can be scrolled to the left during that time. Yes.

  The driver H can position the frame image I2 on the line-of-sight direction EL in which the selected image I1 is viewed by operating the steering wheel side operation unit 6 (see FIG. 5 and the like). Such position adjustment is performed by moving the steering wheel 4 in the vertical direction in addition to the operation by the steering wheel side operation unit 6, and by operating the cross key 5 a of the instrument panel side operation unit 5. Can also be done.

  Although details will be described later, in the present embodiment, when such position adjustment is performed, the display position that has been adjusted is stored, and thereafter, the frame image I2 and the frame image I2 and the display position are stored based on the stored display position. An image I3 is displayed. In the present embodiment, the frame image I2 is configured to be moved by operating the steering wheel side operation unit 6. For example, the frame image I2 is moved by an operation input (for example, a flick operation) by the touch panel unit 40a. It is also possible to configure so as to be able to.

  Next, the control system of the vehicle 1 will be described with reference to FIG.

  As shown in FIG. 4, the control system mainly includes a display control board 100, a first display panel 30, a second display panel 40 (touch panel unit 40a and liquid crystal display unit 40b), an instrument panel side operation unit 5 ( A cross key 5a and a menu screen display switch 5b), a steering wheel side operation unit 6, a steering angle sensor 7 for detecting a steering angle θ of the steering wheel 4, various output devices 8 such as speakers, and a transceiver 9, respectively. Are connected by a distribution cable.

  The display control board 100 is provided on the first display panel 30 and the like, and includes a display control CPU 101, a display control ROM 102, and a display control RAM 103.

  The display control CPU 101 reads a system program or the like stored in advance in the display control ROM 102, and outputs image data to the first display panel 30 and the liquid crystal display unit 40b based on information input from the touch panel unit 40a or the like. At the same time, the operable area designation data is output to the touch panel unit 40a. At this time, the display control CPU 101 outputs audio data and the like to various output devices 8 such as speakers provided in the vehicle 1 as necessary.

  For example, the display control CPU 101 outputs menu screen display data to the first display panel 30 when a menu screen display signal is input by pressing the menu screen display switch 5b. On the other hand, the display control CPU 101 outputs frame image display data for displaying the frame image I2 and character image data for displaying the image I3 on the liquid crystal display unit 40b. In addition, the display control CPU 101 outputs operable area designation data for setting a portion corresponding to the frame image area surrounded by the frame image I2 as an operable area (see FIG. 4) to the touch panel unit 40a. As a result, a “menu display screen” is displayed on the first display panel 30, and a frame image is displayed on the liquid crystal display unit 40b at a position corresponding to each selected image I1 of the “menu display screen”. While I2 is displayed, an image (character image of “menu display screen”) I3 is displayed. In addition, the part corresponding to the frame image I2 in the touch panel unit 40a is effective as an operable area.

  The steering angle sensor 7 according to the present embodiment moves the steering angle data of “0 degree” when the steering wheel 4 is straight, and moves the steering wheel 4 clockwise (counterclockwise) from this state. Steering angle data such as “+1 degree (−1 degree)”, “+2 degree (−2 degree)”, “+3 degree (−3 degree)”... “+ X degree (−X degree)”, It is configured to output to the display control CPU 101.

  Based on the steering angle data input from the steering angle sensor 7, the display control CPU 101 displays a display movement signal for moving the frame image I2 and the image I3 by a predetermined angle on the liquid crystal display unit 40b and the touch panel unit 40a, respectively. The operable region movement signal for moving the operable region by a predetermined angle is output.

  Such control will be described on the assumption that, for example, an operation for moving the steering wheel 4 clockwise from a state in which the steering wheel 4 is straight (steering angle data is 0 degree) is performed.

  When the steering wheel 4 is moved clockwise, as described above, during the movement of the steering wheel 4, the display control CPU 101 displays “+1 degree”, “+2 degree”, “+3 degree”, “+ X”. Steering angle data such as “degree” is continuously input from the steering angle sensor 7.

  When such steering angle data is continuously input, the display control CPU 101 displays the frame image I2 and the image I3 on the liquid crystal display unit 40b counterclockwise by “1 degree”, “2 degrees”, “ Display movement signals such as “−1 degree”, “−2 degrees”, “−3 degrees”, “−X degrees”, which are displayed in a manner shifted by “3 degrees”. Output. Similarly, the display control CPU 101 causes the touch panel unit 40a to set the operable region in a counterclockwise direction by shifting “1 degree”, “2 degrees”, “3 degrees”, “X degrees”. , “−1 degree”, “−2 degree”, “−3 degree”... “−X degree” are continuously output.

  As a result, as shown in FIG. 6, the liquid crystal display unit 40b displays the frame image I2 and the image I3 as the first display panel despite the second display panel 40 being moved clockwise. In the line-of-sight direction EL of the driver H who sees 30, it is possible to display the image as if it is stationary. On the other hand, when the operable region movement signal as described above is input to the touch panel unit 40a, the frame image region of the frame image I2 even when the second display panel 40 is being moved clockwise. Is an operable area.

  The display control ROM 102 stores system programs, various image data output to the first display panel 30, frame image display data and character image data output to the liquid crystal display unit 40b, and a touch panel unit 40a. The operation area designation data for designating the operation area that is output to is stored respectively.

  As various image data displayed on the first display panel 30, “menu screen display data” (for example, output when a menu screen display signal is input from the menu screen display switch 5 b is displayed in the display control ROM 102. 3), “NAVI MENU display data” (see FIG. 5) output when “NAVI” on the menu display screen is selected, and the like are hierarchically stored.

  The frame image display data and the character image data are stored corresponding to various image data displayed on the first display panel 30. The operable area designation data is stored corresponding to the frame image I2 stored in the frame image display data. As the operable region designation data, coordinate data such as X-axis coordinates OO to ΔΔ, Y-axis coordinates XX to □□ are stored for each operable region.

  The display control RAM 103 temporarily stores programs executed by the display control CPU 101, calculation results by the display control CPU 101, and the like.

  The display control RAM 103 is provided with a first display panel image display position storage area and a second display panel image display position storage area.

  The first display panel image display position storage area stores the changed data when the display position of the image displayed on the first display panel 30 is changed by operating the cross key 5a. It is an area to do. The second display panel image display position storage area is an area for storing the changed data when the display positions of the frame image I2 and the image I3 are changed by operating the steering wheel side operation unit 6. is there. The changed data as described above is overwritten and stored every time the position of the image is changed. An image displayed on the first display panel 30 or the liquid crystal display unit 40b is displayed based on data stored in each storage area. Note that the operable area of the touch panel unit 40a is configured to be changed in accordance with the change in the display position of the frame image I2.

  The transceiver 9 transmits the current position of the vehicle 1 to a GPS (Global Positioning System, not shown) satellite and receives position information data transmitted from the GPS satellite when the navigation function is activated. .

  Since the control process in the case of receiving position information data from a GPS satellite is known, a detailed description thereof will be omitted. In brief, when the display control CPU 101 receives position information data from a GPS satellite, A display panel 30 is controlled to display the current vehicle position and map information around it (see FIG. 7).

  Next, control processing of the second display panel 40 executed by the display control CPU 101 will be described with reference to FIG.

  The control process executed by the display control CPU 101 is started when, for example, ACC (accessory power supply) is turned on.

(Step S1)
First, in step S1, the display control CPU 101 determines whether various images (frame image I2 and image I3) are displayed on the liquid crystal display unit 40b.
When the display control CPU 101 determines that various images are displayed on the liquid crystal display unit 40b, the display control CPU 101 moves the process to step S2, and ends the control process when determining that various images are not displayed.

(Step S2)
In step S2, the display control CPU 101 determines whether or not the steering wheel side operation unit 6 has been operated, that is, whether or not there has been an operation to change the display position of various images (frame images I2 and I3).
If the display control CPU 101 determines that an operation for changing the display position of the various images has been performed, the process proceeds to step S3. If the display control CPU 101 determines that there is no operation for changing the display position of the various images, the process proceeds to step S5. Move.

(Step S3)
In step S3, the display control CPU 101 determines whether or not the steering angle data input from the steering angle sensor 7 is 0 degrees (the steering wheel 4 is in a straight state).
If the display control CPU 101 determines that the steering angle data is 0 degree, it moves the process to step S4. On the other hand, if the display control CPU 101 determines that the steering angle data is not 0 degrees, for example, the display control CPU 101 displays a message such as “Please straighten the steering wheel” on the first display panel 30 or the liquid crystal display unit 40b. The processing in step S3 is repeatedly executed until the corner data becomes 0 degrees.

(Step S4)
In step S4, the display control CPU 101 stores the various image display positions changed by the operation of the steering wheel side operation unit 6 in the second display panel image display position storage area (various image display position storage processes). )I do.
For example, when the various images are set to be displayed with the central portion of the liquid crystal display unit 40b as a reference, the various images are displayed in the X-axis direction as ◯, Y, by the operation of the steering wheel side operation unit 6. When moved to xx in the axial direction, data such as X-axis coordinates OO and Y-axis coordinates xx are stored in the second display panel image display position storage area. Thereby, thereafter, the various images are displayed on the liquid crystal display unit 40b with reference to a position shifted from the center of the liquid crystal display unit 40b by XX in the X-axis direction and XX in the Y-axis direction. It becomes.
After performing the various display position storage processes, the display control CPU 101 moves the process to step S5.

(Step S5)
In step S5, the display control CPU 101 determines whether or not an operation for moving the steering wheel 4 has been performed.
The display control CPU 101 determines that there has been an operation of moving the steering wheel 4 when the value of the steering angle data (for example, “5 degrees”) that has been continuously input has changed to a value other than that, The process moves to step S6. On the other hand, when the steering angle data input from the steering angle sensor 7 does not change, the display control CPU 101 determines that there is no operation to move the steering wheel 4 and ends the present control process.

(Step S6)
In step S6, the display control CPU 101 performs an image / operable area movement process.
Hereinafter, the image / operable area moving process will be described in detail. In the following description, a case where the steering wheel 4 is moved clockwise while the steering angle data of “−5 degrees” is input from the steering angle sensor 7 will be described as an example.

  When the steering wheel 4 is moved clockwise, the display control CPU 101 performs steering such as “−4 degrees”, “−3 degrees”, “0 degrees”, “+4 degrees”, and “+5 degrees”. When the angle data is continuously input, “+4 degrees”, “+3 degrees”... “0 degrees”... “−4 degrees”, “−5 degrees”, etc. The display movement signal having the opposite polarity to the steering angle data is continuously output. Similarly, the display control CPU 101 can operate the touch panel unit 40a such as “+4 degrees”, “+3 degrees”, “0 degrees”, “−4 degrees”, and “−5 degrees”. A movement signal is output.

  As a result, various images (frame image I2 and image I3) are displayed on the liquid crystal display unit 40b in a direction opposite to the moving direction (clockwise direction) of the steering wheel 4 in synchronization with the movement of the steering wheel 4 ( It is displayed by moving in a counterclockwise direction. On the other hand, even when the frame image I2 is being moved and displayed, the frame image area of the frame image I2 is set as an operable area.

  For this reason, as shown in FIG. 6, the driver H displays the frame image I2 and the image I3 in the first display regardless of the second display panel 40 (steering wheel 4) being moved clockwise. In the line-of-sight direction EL in which the panel 30 is viewed, it can be seen as if it is stationary. That is, in the present embodiment, the driver H can view the selected image I1 through the frame image I2 even when the second display panel 40 (steering wheel 4) is moved. ing.

  In addition, even when the second display panel 40 is being moved clockwise, the driver H touches the frame image area of the frame image I2 through the touch panel unit 40a, thereby the frame H A selection image I1 corresponding to the image I2 can be selected.

  The display control CPU 101 ends the present control process after performing the image / operable area movement process as described above.

  As described above, according to the present embodiment, since the selection image I1 and the image I3 are displayed separately on the first display panel 30 and the liquid crystal display unit 40b, a plurality of selection images I1 are displayed. It is possible to display the entire display screen of the first display panel 30. For this reason, in the present embodiment, the display size of the selected image I1 can be made larger than when the selected image I1 and the image I3 are displayed on one display screen.

  In the present embodiment, the selection image I1 displayed on the first display panel 30 can be seen through the frame image I2 displayed on the second display panel 40. Therefore, according to the present embodiment, the driver H can view the selected image I1 and the frame image I2 at the same time without moving the line of sight.

As a result, the selection image I1 corresponding to the frame image I2 can be selected. For this reason, according to this embodiment, it is possible to improve not only visibility and safety but also operability.

  In the present embodiment, the frame image I2 and the image I3 are continuously moved in conjunction with the movement of the second display panel 40 (steering wheel 4). However, the present invention is not limited to this. For example, the frame image I2 and the image I3 are configured not to be moved while the second display panel 40 is moving, but to be moved when the movement of the second display panel 40 is stopped. Is also possible.

  In the present embodiment, the second display panel 40 is attached to the steering wheel 4, but in a direction crossing the sight line direction EL of the occupant viewing the first display panel 30 such as a winker lever or a wiper lever. It is also possible to attach to in-vehicle parts that can be moved.

  Further, in the present embodiment, the second display panel 40 is directly attached to the steering wheel 4 as a vehicle-mounted component, but it is also possible to attach it via a support member, for example.

  Moreover, in this embodiment, although the 1st display panel 30 was attached to the instrument panel 3, if it has been arrange | positioned in the position which can be seen through the passenger | crew's 2nd display panel 40, others It can also be attached to other in-vehicle components.

  Further, in the present embodiment, the selection image I1 and the frame image I2 (operable region) are configured to coincide with each other in the sight line direction EL of the occupant by operating the steering wheel side operation unit 6 or the like. In addition, for example, when an in-vehicle camera that detects the occupant's viewpoint is provided in an in-vehicle component such as the instrument panel 3 and the detection sensor detects the movement of the occupant's viewpoint, the selection image I1 is automatically selected. And the frame image I2 (operable region) can be configured to coincide with each other. With such a configuration, when the occupant's viewpoint moves, the image (for example, the frame image I2) displayed on the second display panel 40 is displayed on the occupant's viewpoint and the first display panel 30. (For example, it can be realized by moving so as to be positioned on a straight line connecting the selected image I1).

  As mentioned above, although embodiment which applied the invention made | formed by this inventor was described, this invention is not limited by the description and drawing which make a part of indication of this invention by this embodiment.
