This is information on a detected value (measured value or the like) about the state of the vehicle such as the amount and the position of the gear of the vehicle (that is, the gear position). In addition, as auxiliary information, there is information on the position of the vehicle such as the position of the vehicle represented by latitude and longitude and the scenery around the vehicle.

  A vehicle information image representing instrument information (hereinafter referred to as instrument image) is an instrument image representing the detected value. A vehicle information image representing auxiliary information (hereinafter referred to as an auxiliary image) is an image (in a so-called car navigation system) representing the position of the vehicle represented by latitude and longitude by indicating the position of the vehicle on a map. Navigation image), and a night vision image (a so-called night view image in a night vision system) representing the position of the vehicle by photographing a landscape around the vehicle with a night vision camera attached to the vehicle.

  As shown in FIG. 1, the vehicle display control device 100 includes a display control unit 101 and an instrument display unit 109. A display control unit 101 that controls the display of the instrument display unit 109 includes a CPU (Central Processing Unit) 101a, a flash memory 101b, a RAM (Random Access Memory) 101c, an input unit 101d, a drawing LSI (Large Scale Integration) 101e, and a graphic A memory 101f is provided.

  The CPU 101a executes processing according to a program stored in the flash memory 101b, thereby controlling each unit constituting the vehicle display control device 100 and performing processing described later. For example, the CPU 101a generates image data of the entire image to be displayed on the instrument display unit 109 according to the above program, and outputs the generated image data to the drawing LSI 101e.

  The CPU 101a is connected to an ECU (Engine Control Unit) 200 via a communication interface (hereinafter simply referred to as a communication IF) 300 and the serial bus 10, and the CPU 101a communicates with the ECU 200 via these.

  The flash memory 101b stores data used by the CPU 101a, such as graphic data used for generating image data, in addition to the above programs.

  The RAM 101c functions as a main memory that temporarily stores data used by the CPU 101a during processing.

  The input unit 101d includes operation buttons that accept various operations from a user, a touch panel sensor unit, and the like. The input unit 101d receives an operation from the user, generates an operation signal indicating the received operation, and outputs the operation signal to the CPU 101a. As an operation from the user, there is an operation of switching an image to be displayed on the instrument display unit 109. An operation signal indicating an operation for switching an image displayed on the instrument display unit 109 is supplied to the CPU 101a as a switching instruction signal. Note that the CPU 101a may acquire the switching instruction signal from the ECU 200 via the communication IF 300.

  The drawing LSI 101e receives the image data supplied from the CPU 101a and develops the entire image data on the graphic memory 101f based on the received image data. Thereafter, the drawing LSI 101e outputs the data of the entire developed image to the instrument display unit 109, and the instrument display unit 109 displays the image. Thus, the drawing LSI 101e has a function of drawing an image on the instrument display unit 109, and the CPU 101a displays an image (entire image) on the instrument display unit 109 using the drawing LSI 101e.

  The instrument display unit 109 includes, for example, a TFT (Thin Film Transistor) LCD (Liquid Crystal Display) 109a and a backlight module 109b that is installed behind the LCD 109a and illuminates the LCD 109a, and is output by the drawing LSI 101e. The entire image is displayed using the LCD 109a and the backlight module 109b. The LCD 109a is also a touch panel including a touch panel sensor unit (input unit 101d). That is, the instrument display unit 109 includes a touch panel.

  The ECU 200 is connected to a vehicle speed sensor 210, a vehicle output detection unit 220, a water temperature sensor 230, a fuel remaining amount sensor 240, and a gear position detection unit 250, and the vehicle speed, vehicle output, and water temperature detected by each sensor and detection unit. Analog signals representing the remaining amount of fuel and the gear position are acquired from the respective sensors and detection units. Thereafter, the ECU 200 uses an analog-to-digital (A-D) converter to convert an analog signal into digital data, and then converts the converted data into a vehicle display control by, for example, CAN (Controller Area Network) communication. Transmit to device 100. These digital data correspond to data representing instrument information.

  The ECU 200 is connected to a night-view camera 260 that is a night vision camera and a global positioning system (GPS) receiver 270. The ECU 200 acquires night-vision image data representing a night-vision image (that is, night view) captured by the night-view camera 260 from the night-view camera 260, and the host vehicle representing the position of the host vehicle detected by the GPS receiver 270. Position data is acquired from the GPS receiver 270, and each acquired data is transmitted to the vehicle display control device 100. These data correspond to data representing auxiliary information.

  Next, display setting information acquired by the vehicle display control apparatus 100 will be described. The CPU 101a in FIG. 1 acquires information representing a reduction pattern designated by the user (hereinafter referred to as reduction pattern information) based on the operation signal supplied from the input unit 101d.

  In the reduction pattern, for example, as shown in FIGS. 4 to 6, the currently displayed vehicle information image is reduced as a whole, and the newly displayed vehicle information image is gradually enlarged in accordance with this, and finally There is a reduction pattern A for displaying a vehicle information image after switching and a trace image (for example, a black circle in FIG. 6) representing a trace of the vehicle information image before switching. In another example, as shown in FIGS. 7 to 11, the currently displayed vehicle information image is compressed from the top and bottom to form a line segment, and then the line segment length is reduced and newly displayed accordingly. There is a reduction pattern B that gradually enlarges the vehicle information image and finally displays the vehicle information image after switching and the trace image of the vehicle information image before switching (for example, a black circle in FIG. 11). When the currently displayed vehicle information image is reduced, the newly displayed vehicle information image may not be enlarged gradually. In this case, for example, when the trace image of the vehicle information image before switching is finally displayed, the vehicle information image after switching is displayed.

  Further, the CPU 101a acquires information (hereinafter referred to as trace information) representing a final shape (a shape of the trace image) of the vehicle information image specified by the user based on the operation signal. The CPU 101a acquires information (hereinafter referred to as arrangement position information) indicating the arrangement position of the final shape (trace) designated by the user based on the operation signal. Based on the operation signal, the CPU 101a acquires information (hereinafter referred to as switching time information) indicating the time required to switch the display image designated by the user. That is, the user can designate the shape of the trace image, the arrangement position of the trace image, and the switching period.

  The CPU 101a stores each piece of information acquired based on the operation signal as display setting information in the flash memory 101b of FIG. The CPU 101a may acquire any one of the reduced pattern information, the trace information, the arrangement position information, and the switching time information, or a combination of two or more thereof. The display setting information may be acquired from the ECU 200 via the communication IF 300, or may be originally programmed and stored in the flash memory 101b.

  Next, processing performed by the CPU 101a of the vehicle display control apparatus 100 will be described. The CPU 101a in FIG. 1 executes display control processing as shown in FIG. First, when a voltage is applied from the battery to both ignition terminals, the vehicle display control device 100 is started. The CPU 101a of the vehicle display control apparatus 100 starts display control processing by this start.

  The CPU 101a reads display setting information stored in the flash memory 101b (step S01). Next, CPU101a starts acquisition of various vehicle information (step S02). For example, when the vehicle display control apparatus 100 is started, first, the CPU 101a requests the ECU 200 of FIG. 1 to transmit various vehicle information, and causes the ECU 200 to transmit data representing the various vehicle information. In this manner, the CPU 101a starts acquiring data representing various instrument information and auxiliary information from the ECU 200. Thereafter, the CPU 101a continues to acquire data representing various vehicle information periodically during the display control process.

  Next, the CPU 101a causes the instrument display unit 109 to display an overall image in which one or more vehicle information images representing predetermined vehicle information among the acquired various vehicle information are incorporated (step S03). When the predetermined vehicle information images are an instrument image representing the vehicle speed (speedometer image) and an instrument image representing the vehicle output (tachometer image), the CPU 101a is an instrument image representing the vehicle speed. Image data of an entire image including a speedometer image C1 and an engine speed image C2 indicating vehicle information which is a meter image representing the engine speed is generated and supplied to the drawing LSI 101e, and the entire image is displayed on the instrument display. Displayed on the unit 109.

  Specifically, the CPU 101a reads a speedometer master image or the like from the flash memory 101b of FIG. 1, and based on the vehicle information representing the vehicle speed acquired from the ECU 200, the pointer image indicating the speed is a master image of the speedometer. To generate a speedometer image C1. Similarly, the CPU 101a reads a tachometer (that is, a tachometer) master image or the like from the flash memory 101b of FIG. 1, and calculates the engine speed based on the vehicle information representing the engine speed acquired from the ECU 200. The pointer image of the pointer shown is combined with the master image of the tachometer to generate a tachometer image C2.

  Then, the CPU 101a reads out the initial master image of the entire image from the flash memory 101b in FIG. 1, combines the speedometer image C1 and the revolution meter image C2 with this master image, and displays the entire image as shown in FIG. D is generated. By such processing, the CPU 101a generates image data of the entire image D, supplies the image data to the drawing LSI 101e, and performs control to display the entire image D on the instrument display unit 109.

  In the subsequent processing, the CPU 101a displays the currently displayed vehicle information image (including the vehicle information image newly displayed in the subsequent processing) among the vehicle information periodically supplied from the ECU 200. Using the vehicle information to be used, new image data of the entire image is generated according to the above procedure, and the process of supplying the image data to the drawing LSI 101e is repeated in real time (image update). Accordingly, the partial image displayed on the instrument display unit 109 changes in real time according to the change in the content of the vehicle information, so that the vehicle information is displayed in real time.

  Next, the CPU 101a determines whether or not a switching instruction signal is input to the input unit 101d (step S04). When the switching instruction signal is not input to the input unit 101d (step S04; NO), the CPU 101a performs the process of step S04 again and continues to monitor the switching instruction signal. When a switching instruction signal is input to the input unit 101d (step S04; YES), the CPU 101a receives the switching instruction signal from the input unit 101d and is currently displayed based on the display setting information read in step S01. The information image is reduced (step S05). And CPU101a displays the image (henceforth a trace image) showing the trace of the vehicle information image before switching, and the vehicle information image after switching (step S06), and returns to the process of step S04. The display control process is continued until the operation of the vehicle display control apparatus 100 ends, for example, when the ignition is turned off.

  Specifically, the CPU 101a reduces the vehicle information image currently displayed with the reduction pattern indicated by the reduction pattern information. The CPU 101a finally displays the vehicle information image after switching, and also displays the trace image of the vehicle information image before switching at the arrangement position indicated by the arrangement position information. The CPU 101a performs the display switching in the time indicated by the switching time information.

  For example, when the user activates the night vision system in the state of FIG. 3, a switching instruction signal for switching from displaying the speedometer image and the tachometer image to displaying the night view image is input to the CPU 101a. When the reduced pattern information is the reduced pattern A among the display setting information read from the flash memory 101b, first, the CPU 101a, as shown in FIG. 4, between a speedometer image C1 and a tachometer image C2, a predetermined value. The night view image Cn reduced in size is displayed. Next, the CPU 101a gradually reduces the speedometer image C1 and the tachometer image C2, and gradually enlarges the night view image Cn accordingly. In this intermediate stage, the display is as shown in FIG. Then, as shown in FIG. 6, the CPU 101a finally displays the entire image D including the night view image Cn, the trace image C11 representing the trace of the speedometer image C1, and the trace image C21 representing the trace of the revolution meter image C2. Is displayed on the instrument display unit 109.

  On the other hand, when the reduced pattern information is the reduced pattern B among the display setting information read from the flash memory 101b, first, the CPU 101a, between the speedometer image C1 and the tachometer image C2, as shown in FIG. The night view image Cn reduced to a predetermined size is displayed. Next, the CPU 101a gradually compresses the vertical widths of the speedometer image C1 and the tachometer image C2 as shown in FIG. When the CPU 101a compresses the vertical width of the speedometer image C1 and the tachometer image C2 until it becomes a line segment as shown in FIG. 9, the line segment length is then gradually shortened, and the night view image Cn is adjusted accordingly. Gradually expand. In this intermediate stage, the display is as shown in FIG. Then, the CPU 101a finally causes the instrument display unit 109 to display the entire image D including the trace image C11 and the trace image C21 together with the night view image Cn, as shown in FIG.

  In addition, instead of the night view image Cn reduced to a predetermined size displayed at the start of display switching as shown in FIG. 4 or FIG. 7, a trace image (for example, a black circle) representing the trace of the night view image Cn is displayed. It may be displayed.

  When the user performs an operation for redisplay and restores the trace image C11 and the trace image C21 to the speedometer image C1 and the tachometer image C2, the CPU 101a acquires a switching signal indicating such redisplay. In steps S05 to S06, a process reverse to the above process is performed. That is, in the case of the reduced pattern A, the CPU 101a displays a speedometer image C1 and a tachometer image C2 reduced to a predetermined size instead of the trace image C11 and the trace image C21. The CPU 101a gradually enlarges the reduced speedometer image C1 and the revolution meter image C2, and gradually reduces the night view image Cn accordingly. In this intermediate stage, the display is as shown in FIG. Then, the CPU 101a finally displays the entire image D including the speedometer image C1 and the revolution meter image C2 and the night view image Cn reduced to a predetermined size on the instrument display unit 109 as shown in FIG. Display.

  In the case of the reduced pattern B, the CPU 101a displays a speedometer image C1 and a speedometer image C2 reduced to a predetermined size instead of the trace image C11 and the trace image C21. The CPU 101a gradually enlarges the lateral widths of the speedometer image C1 and the revolution meter image C2 reduced to a predetermined size, and gradually reduces the night view image Cn accordingly. When the CPU 101a enlarges the horizontal width of the speedometer image C1 and the tachometer image C2 until it becomes a line segment as shown in FIG. 10, it then gradually expands the vertical width. In this intermediate stage, the display is as shown in FIG. Then, the CPU 101a finally displays the entire image D including the speedometer image C1 and the revolution meter image C2 and the trace information of the night view image Cn reduced to a predetermined size as shown in FIG. Displayed on the unit 109. In addition, instead of the night view image Cn reduced to a predetermined size displayed at the time of restoration of the speedometer image C1 and the tachometer image C2, a trace image (eg, a black circle) representing the trace information of the night view image Cn. ) May be displayed.

  The operation for redisplay is, for example, a case where the input unit 101d includes a touch panel sensor unit that is touched by the user to input an operation (that is, the sensor unit and the instrument display unit constitute a touch panel). The user touches the area where the trace image on the touch panel is displayed. In this case, the CPU 101a receives from the input unit 101d a switching instruction signal for switching from the currently displayed vehicle information to the display of the original vehicle information of the trace image.

  In addition, the trace information may be displayed by directly displaying the vehicle information image reduced to a predetermined size as the trace image, or the vehicle information image may be displayed up to a predetermined size (for example, the same vertical and horizontal width as the black circle of the trace image). When the image is reduced, it may be replaced with a trace image such as a black circle. Similarly, in the reduction pattern B, when the vertical widths of the speedometer image C1 and the tachometer image C2 are compressed until they become line segments, they may be replaced with line segment images.

  In the example of FIGS. 6 and 11, the trace image C11 representing the trace information of the speedometer image C1 and the trace image C21 representing the trace information of the speedometer image C2 are displayed together with the night view image Cn. The trace image may be erasable. In this case, the trace image C11 and the trace image C21 are not completely erased, but the data of the trace images (the trace image C11 and the trace image C21) in which the display is temporarily erased and the display is temporarily erased are stored. Store in the RAM 101c. Further, when the trace image is erased by the user's operation, the user may be guided to the operation for redisplaying the trace image. Similarly, the trace image of the night view image Cn when the trace image C11 and the trace image C21 are restored to the speedometer image C1 and the revolution meter image C2 as described above may be made erasable.

  Note that the operation for redisplaying the trace image when the trace image is erased is, for example, an operation in which the user touches an arbitrary place on the touch panel. When the CPU 101a receives an operation signal from the input unit 101d when the user touches an arbitrary place on the touch panel, the CPU 101a re-displays the trace image stored in the RAM 101c, which has been temporarily deleted, at the original arrangement position. .

  As described above, according to the vehicle display control apparatus 100 of the present embodiment, when another image is displayed on the instrument display unit 109 instead of a certain vehicle information image, the trace indicating the trace of the vehicle information image is displayed. Since the image is displayed on the instrument display unit 109 together with the other images, the trace of the previously displayed vehicle information image remains in the screen newly displayed by the instrument display unit 109. Therefore, the impression that the vehicle information image still remains on the instrument display unit 109 can be given to the user by this trace, so that when the vehicle information image is switched to another image, the previous vehicle information image is displayed. It is possible to reduce the user's anxiety that it may not be possible to re-display easily. In particular, this is effective because the user who is driving cannot view the instrument display unit 109 for a long time. In the above description, the other images are also vehicle information images. However, the other images may not be vehicle information images.

  In the above embodiment, the vehicle information image is gradually reduced, and the vehicle information image is changed so as to finally become a trace image. Here, the trace image may be an image obtained by reducing the vehicle information image, or may be an image replaced with a predetermined figure during the reduction. The shape of the trace image may be another shape. The trace image is an image that cannot recognize the content (detection value, etc.) and type (vehicle speed, rotation speed, etc.) of the vehicle information represented by the original vehicle information image. It is desirable that the image is smaller than the vehicle information image (particularly, it is desirable that the image is so small that the content and type of the vehicle information cannot be recognized). Further, the trace image represents only the trace, and the significance of the trace image becomes clear. Further, since the trace image is a small image, a display space of the instrument display unit 109 is secured. The trace image is particularly preferably a dot-like image such as a black circle in the present embodiment. Thereby, a display space is secured.

  In the present embodiment, the display control unit 101 of the vehicle display control device 100 shown in FIG. 1 controls the display of an external display unit, and the vehicle display control device 100 controls the external display unit. May function as

  In the present embodiment, with the above configuration, the instrument display unit 109 includes a touch panel on which a user touches and inputs an operation, and the CPU 101a corresponds to trace information when the user touches a trace image on the touch panel. A redisplay process for redisplaying the original vehicle information image on the instrument display unit 109 is further performed. As a result, the user can intuitively redisplay the image.

  Further, the display control unit 101 includes another nonvolatile storage device such as a hard disk in addition to the flash memory 101b or instead of the flash memory 101b, and the other nonvolatile storage device stores the flash memory 101b. You may memorize | store at least one part of the program and data to perform.

  Moreover, the instrument display part 109 does not need to display an instrument image temporarily at all.

  Further, the vehicle display control device according to the present invention may function as a display control device for controlling an external instrument display unit without including the instrument display unit 109.

  In addition, CPU101a may acquire only the vehicle information required for the display of a whole image among various vehicle information. In this case, the CPU 101a supplies an acquisition request for necessary vehicle information to the ECU 200, and the ECU 200 supplies necessary vehicle information to the CPU 101a based on the acquisition request. In such a case, the ECU 200 may not operate sensors, detection units, devices, and the like that are unnecessary for supplying vehicle information.

  Further, the vehicle display control apparatus according to the present invention may be for other vehicles such as a ship, a two-wheeled vehicle, and an airplane. Driving includes expressions such as maneuvering about an airplane.

  The distribution method of the program for operating the CPU 101a is arbitrary. For example, the program can be distributed by being stored in a recording medium such as a memory card, CD-ROM, or DVD-ROM, or via a communication medium such as the Internet. You can also. In this manner, the computer may function as the vehicle display control device by installing the program in the computer.
