A database 57 that stores data relating to features such as display shape and display color of information displayed in the display area, a drawing RAM 59 that stores image data to be output to the display device 33, and image data stored in the drawing RAM 59. A display controller 61 that reads out, calculates a display position so that a display image is displayed at an appropriate position on the windshield 5, and outputs image data to the display devices 33a and 33b, a wireless communication device 9, and a GPS receiver 11 , The vehicle speed sensor 13, the direction sensor 15, and the database 57 are connected, and the CPU 51, RAM 55, drawing RAM 5 are connected. And an output section 63 for inputting and outputting signals and data to and from the display controller 61.

The database 57 may use a CD-ROM, a DVD-ROM, or the like as a storage medium, or a writable storage medium such as a memory card or a hard disk.
In the control unit 31 configured as described above, the CPU 51 performs display processing related to the characteristic part of the present embodiment.

  Next, the display processing procedure executed by the CPU 51 will be described with reference to FIG. FIG. 3 is a flowchart showing the display process. This display process is repeatedly executed while the vehicle ignition key is inserted into the key cylinder and the key is changed to ON.

  In this display process, the CPU 51 first specifies the current position and traveling direction of the vehicle in S10. That is, the current position and traveling direction of the vehicle are calculated based on various signals output from the GPS receiver 11, the vehicle speed sensor 13, and the direction sensor 15. Thereafter, in S20, it is determined whether there is information transmitted from the wireless communication device 9. If it is determined that there is information to be transmitted (S20: YES), the process proceeds to S40. On the other hand, if it is determined that there is no information to be transmitted (S20: NO), the process proceeds to S30.

  When the process proceeds to S30, it is determined whether there is information received by the wireless communication device 9. If it is determined that there is received information (S30: YES), the process proceeds to S120. On the other hand, if it is determined that there is no received information (S30: NO), the process proceeds to S10 and the above-described processing is repeated.

  When the process proceeds to S40, the position of the reception destination of the information to be transmitted is specified. That is, the information (for example, latitude, longitude, height) of the position where the external device that is the reception destination is installed is acquired.

  Next, the characteristic of display information is specified in S50. That is, based on the information to be transmitted, it is determined what kind of information is transmitted, and the features such as the display shape and display color corresponding to the information are acquired from the database 57.

  Thereafter, in S60, the position in the display area of the windshield 5 where the display information is displayed is specified. That is, the moving path of the moving object 102 in FIG. 5 is set. Here, according to the current position and traveling direction of the vehicle calculated in S10 and the position of the receiving destination acquired in S40, where to display in the display area of the windshield 5 when viewed from the occupant's eye point, The movement route is set in consideration of the viewing position of the stereoscopic display. Since the viewing position of the stereoscopic display differs depending on the occupant's eye point, the occupant's eye point may be estimated and the display position when the windshield 5 is watched from this eye point may be set. For example, the standard eyepoint may be estimated based on the physique, body shape, driving posture, standard line-of-sight direction, etc. of the passenger sitting in the driver's seat, and further, the seat slide position, reclining angle, etc. And the standard eye point may be corrected using the detected data.

  In step S70, image data to be output to the display devices 33a and 33b is written in the drawing RAM 59. Thereafter, a display command is issued to the display controller 61 at S80. The display controller 61 receives this command, reads out the image data stored in the drawing RAM 59, and outputs display light for display on the display devices 33a and 33b.

  Further, in S90, the transmission progress in the wireless communication device 9 is specified, and in S100, the display size is changed and the display position is moved according to the transmission progress. Here, in consideration of the viewing position of the stereoscopic display, the setting of the display controller 61 is changed to change the display size and move the display position.

  Thereafter, in S110, it is determined whether or not the display has moved to the receiving destination. If it is determined that the display has not moved to the receiving destination (S110: NO), the process proceeds to S90 and the above-described processing is repeated. On the other hand, if it is determined that the display has moved to the receiving destination (S110: YES), the display process is terminated.

  If the process proceeds to S120, the position of the transmission source of the received information is specified. That is, as in S40, information (for example, latitude, longitude, height) of the position where the external device that is the transmission source is installed is acquired.

  Next, in S130, the characteristics of the display information are specified. That is, based on the received information, it is determined what kind of information has been received, and features such as display shape and display color corresponding to the information are acquired from the database 57.

  Thereafter, in S140, it is specified at which position in the display area of the windshield 5 the display information is to be displayed. That is, the moving path of the moving object 202 in FIG. 6 is set. That is, as in S60, when viewed from the occupant's eyepoint from the current position and traveling direction of the vehicle calculated in S10 and the transmission source position acquired in S120, the display is displayed at any position in the display area of the windshield 5. Whether to move or not is set in consideration of the viewing position of the stereoscopic display.

  In step S150, image data to be output to the display devices 33a and 33b is written in the drawing RAM 59. Thereafter, a display command is issued to the display controller 61 in S160. The display controller 61 receives this command, reads out the image data stored in the drawing RAM 59, and outputs display light for display on the display devices 33a and 33b.

  Further, in S170, the reception progress in the wireless communication device 9 is specified, and in S180, the display size is changed and the display position is moved according to the reception progress. Here, the setting of the display controller 61 is changed in consideration of the viewing position of the stereoscopic display, and the display size is changed and the display position is moved.

  Thereafter, in S190, it is determined whether or not the display has moved to the host vehicle. If it is determined that the display has not moved to the host vehicle (S190: NO), the process proceeds to S170 and the above-described processing is repeated. On the other hand, if it is determined that the display has moved to the host vehicle (S190: YES), the received detailed information is displayed on the windshield 5 in S200, and the display process is terminated.

The operation of the stereoscopic display system 1 configured as described above will be described with reference to FIGS.
5 to 7 are image diagrams of a vehicle traveling toward the ETC lane when the front of the vehicle is viewed through the windshield 5 from an occupant's eye point in the vehicle. → The time has passed in the order of FIG.

  A communication device in the ETC lane (hereinafter referred to as a lane communication device) is installed in the ETC lane and is used for communication with an ETC on-vehicle device mounted on a vehicle entering the ETC lane. The lane communication device is configured to transmit the ETC lane position information and the like when the vehicle enters the ETC lane, and further to transmit the fee information and the like when the vehicle information is received from the ETC onboard device. ing.

  When the vehicle enters the ETC lane, the ETC vehicle-mounted device (corresponding to the wireless communication device 9 of the present embodiment) receives position information and the like from the ETC lane, and then transmits the own vehicle information to the lane communication device. . FIG. 5 shows the situation when the ETC on-board unit transmits the own vehicle information to the lane communication device, and the ETC on-board device moves from the own vehicle to the destination 101 while decreasing in size according to the transmission progress. A moving image expressing the moving object 102 in three dimensions is displayed on the windshield 5 (see S90 to S110). The position of the receiving destination 101 is determined based on the position information received from the lane communication device by the ETC on-board unit (see S40). The moving object 102 is expressed as a pattern imitating an ETC card (see S50).

  Thereafter, when the lane communication device that has received the own vehicle information from the ETC on-vehicle device transmits the fee information or the like to the own vehicle, the ETC on-vehicle device receives the fee information or the like. FIG. 6 shows the situation when the ETC on-board unit is receiving fee information and the like, and it is moving from the transmission source 201 toward the host vehicle while increasing in size according to the reception progress. A moving image in which the moving object 202 is three-dimensionally displayed is displayed on the windshield 5 (see S170 to S190). Note that the position of the transmission source 201 is determined based on the position information received from the lane communication device by the ETC on-board unit (see S120). The moving object 202 is expressed as a sphere with an ETC logo on the surface (see S130).

  When the moving object 202 is displayed until it reaches the host vehicle, the moving object 202 disappears. Immediately thereafter, the detailed display 302 such as fee information is displayed on the windshield 5 as shown in FIG. (See S200).

Thus, by displaying a moving image on the windshield 5, a passenger in the vehicle can visually recognize that transmission / reception is being performed between the ETC in-vehicle device and the lane communication device.
In the stereoscopic display system 1 of the present embodiment configured as described above, when information is transmitted from the wireless communication device 9 to the reception destination 101, a moving image representing the moving object 102 moving away from the vehicle 3 to the reception destination 101 is displayed in a window. Display on shield 5. Further, when information is received from the transmission source 201 to the wireless communication device 9, a moving image representing the moving object 202 approaching the vehicle 3 from the transmission source 201 is displayed on the windshield 5.

  That is, when the wireless communication device 9 transmits information, it means that information is transmitted far away, so that an occupant of the vehicle 3 imagines the transmission of the wireless communication device 9 and the expression that the moving object 102 moves away. Easy to match. Similarly, when the wireless communication device 9 receives information, it means that information coming from a distance is received, so that an occupant of the vehicle 3 receives the wireless communication device 9 and the moving object 202 approaches the vehicle. It is easy to match the expression with image. In other words, since it is possible to capture the presence / absence of transmission / reception by the wireless communication device 9, it is possible to reduce the time required for the occupant to recognize that there is transmission / reception, compared to the case where the transmission / reception is performed using characters or still images. .

  Further, the moving object 102 moves away toward the receiving destination 101, and similarly, the moving object 202 displays a moving image approaching from the transmission source 201. That is, since it is possible to grasp the image that the wireless communication device 9 is transmitting to the reception destination and the wireless communication device 9 is receiving from the transmission source, it is more wireless than the case of displaying characters or still images. It is possible to reduce the time required for the occupant to recognize that the communication device 9 is transmitting to the reception destination and that the wireless communication device 9 is receiving from the transmission source.

  Further, after the display of the moving image in which the moving object 202 approaches the vehicle 3 is completed, the detailed display 302 is displayed on the windshield 5. For this reason, if the occupant who recognizes that there is a reception by viewing a moving image of the moving object 202 approaching the vehicle 3 determines that there is no need to check the content of the received information, the occupant displays the detail display 302. Since it is not necessary to confirm, time spent for understanding unnecessary information can be reduced.

  Also, the moving object 102 moves closer to the receiving destination 101 as the transmission progresses according to the progress of the transmission by the wireless communication device 9, or the moving object as the reception progresses according to the progress of the reception by the wireless communication device 9. Since a moving image is displayed on the windshield 5 so that 202 approaches the vehicle 3, the passenger of the vehicle 3 understands how much communication by the wireless communication device 9 is advanced by viewing this moving image. be able to.

  Further, the moving object 102 is reduced in size as the transmission progresses according to the progress of the transmission by the wireless communication device 9, or the moving object as the reception progresses according to the progress of the reception by the wireless communication device 9. Since a moving image is displayed on the windshield 5 so that the size of 202 becomes large, it becomes easy for the passenger of the vehicle 3 to recognize that the moving object 102 is moving away or the moving object 202 is approaching.

  In addition, since stereoscopic display is performed on the windshield 5 using the binocular parallax of the occupant, the moving objects 102 and 202 are displayed so that a sense of perspective can be felt. For this reason, it becomes easy for the passenger | crew of the vehicle 3 to recognize that the moving object 102 moves away or the moving object 202 approaches.

  The moving object 102 is expressed as a pattern imitating an ETC card, and the moving object 202 is expressed as a sphere with an ETC logo written on the surface. That is, the pattern of the moving object changes according to the type of information transmitted / received. For this reason, the passenger | crew of the vehicle 3 can understand what kind of information is transmitted / received by seeing this moving image.
