Next, features of the present invention will be described with reference to FIGS.
The control means 103 obtains vehicle information (input information) via the interface means 102, selects background images 201 a to 201 d from the image storage means 105 according to this vehicle information, and multi-displays via the display drive means 106. Display on device 10. At this time, sound / audio reproduction corresponding to the background images 201a to 201d is performed via the sound / audio reproduction means 108 and the speaker 109.

  Specifically, when the user opens the door of the vehicle, an input signal from a door switch (not shown) is received as vehicle information by the control means 103 via the vehicle interface terminal 101 and the interface means 102, and the control means 103 Determines the open / close state of the door based on an input signal from the door switch, and determines that the door is “open” (switched from the door “closed” to the door “open”). The first background image 201a is selected from 200e, and the opening image is displayed on the multi-display device 10 (see FIG. 4).

  The background image 201a is stored in the image storage unit 105 as a background image of a plurality of frames incorporating a part of the appearance image of the vehicle body, and the control unit 103 reproduces the background image 201a as a moving image (for example, 24 (Frame / second), and a performance that welcomes the driver (user) to the driver's seat.

  At this time, the control means 103 reproduces the music 202a stored in the sound / audio area of the image storage means 105 as sound effects (auditory information) in parallel with the moving image reproduction of the background image 201a. As a result, in addition to visual effects, auditory effects are also provided.

  Next, when the user operates an ignition switch (key switch) (not shown), an input signal from the ignition switch as vehicle information is received by the control means 103 via the vehicle interface terminal 101 and the interface means 102, and the control means 103 Determines the operation state (presence / absence of operation) based on the input signal from the ignition switch. When it is determined that the operation has been performed, the second background image 201b is selected from the selection timings 200a to 200e of the image storage unit 105, It is displayed on the multi-display device 10 as an initial image (see FIG. 5).

  This background image 201b is a combination of a front view image (appearance image) of a vehicle body with a landscape image (for example, an artificial landscape such as a road or a building, or a natural landscape such as trees, forest, sea, or mountains). This will produce a sense of realism that will start driving.

  At this time, the control means 103 reproduces the sound 202b stored in the sound / audio area of the image storage means 105 in parallel with the reproduction of the background image 201b. The voice 202b is reproduced as a greeting message (auditory message) “Good morning”, thereby producing a pseudo communication between the user and the vehicle.

  Incidentally, the sound 202b to be such greeting message, Yes in advance a plurality of types prepared (e.g., "Hello" or "Good evening"), by obtaining the time information as the vehicle information, greeting selected according its time It has come to be. Such a greeting message can also be displayed as character information (various information).

  Next, when the reproduction of the background image 201b and the sound 202b ends and the driving standby state is set (assuming that the engine is in an operating state at this time), the control means 103 continues the display of the background image 201b, Vehicle speed information (various information) of vehicle speed “0 km / h” and shift position information (various information) of “PRND432” are displayed on the background (see FIG. 6).

  The vehicle speed value is a value based on a detection state (vehicle information) of a vehicle speed sensor (not shown), which is received via the vehicle interface terminal 101 and the interface means 102 and obtained through arithmetic processing by the control means 103. Similarly, the position information is based on the detection state (vehicle information) of a shift position sensor (not shown).

  Next, when the vehicle starts running and the vehicle speed reaches a first predetermined speed (for example, “10 km / h”), the control unit 103 causes the third background image 201b from the selection timings 200a to 200e of the image storage unit 105. While selecting the same as the second background image and continuing to display the background image 201b and the shift position information, the sound 202c stored in the sound / sound area of the image storage means 105 is reproduced (FIG. 7). ). This voice 202c is reproduced as a warning message (auditory information) “Let's keep driving safely”, and this also produces pseudo communication between the user and the vehicle. Moreover, such a warning message can also be displayed as character information (various information).

  Next, after the reproduction of the sound 202c is completed, the control means 103 displays the background image 201b and the shift position information as long as the vehicle speed is equal to or less than a certain speed (for example, 100 km / h or less) (FIG. 8).

  Next, when the vehicle speed reaches a certain speed or more (for example, 101 km / h or more), the control means 103 selects the fourth background image 201c from the selection timings 200a to 200e of the image storage means 103, and shifts as the background image. The information is displayed on the multi-display device 10 together with the information (FIG. 9).

  The background image 201c is a combination of a landscape image of a flowing image and a front view image (appearance image) of the vehicle body, and produces a figure of a vehicle traveling at high speed.

  At this time, the control means 103 reproduces the sound 202d stored in the sound / sound area of the image storage means 105 in parallel with the reproduction of the background image 201c. This voice 202d is reproduced as a warning message (auditory information) of “speed attention”. If the vehicle speed is equal to or lower than a certain speed (for example, 101 km / h or lower), the vehicle speed at that time is displayed on the background image 201b as shown in FIG.

  Next, when the ignition key is turned off while the vehicle is stopped, the control unit 103 selects the fifth background image 201d from the selection timings 200a to 200e of the image storage unit 105, and serves as an ending image for the multi-display device 10. It is displayed (FIG. 10).

  The background image 201d is a combination of a landscape image and a rear view image (appearance image) of the vehicle body, and produces an end of driving (ending).

  At this time, the control means 103 reproduces the sound 202e stored in the sound / sound area of the image storage means 105 in parallel with the reproduction of the background image 201d. This voice 202e is reproduced as a greeting message (auditory information) that says "Thank you for your hard work", and this also produces pseudo communication between the user and the vehicle. Such a greeting message can also be displayed as character information (various information).

  The above is a series of display operation examples of the vehicle display device 1 from when the vehicle door is opened until the ignition switch is turned off. In this example, operation information (vehicle information) of the ignition switch, time information, vehicle speed sensor The vehicle display device 1 is obtained by obtaining a plurality of input information consisting of vehicle speed detection information (vehicle information) of the vehicle, selecting background images 201a to 201d according to the information, and displaying them on the display device 10. As described above, the background images 201a to 201d may be selected according to information, weather (weather) information, and timekeeping information (for example, travel time or engine operation time).

  In addition, when obtaining date, travel time, and heaven information as input information, and selecting and displaying a background image according to this information (not shown), the season is from the date information, and the user's fatigue is from the time information. Needless to say, it is possible to grasp the road surface condition and the like from the ceiling information, and to prepare and select a background image corresponding to the input information.
