For example, a geomagnetic sensor for detecting the absolute azimuth of the vehicle, a gyroscope for detecting the relative azimuth of the vehicle, a distance sensor for detecting the mileage of the vehicle, and a global that measures the position of the vehicle based on radio waves from the satellite A GPS receiver or the like for a positioning system (GPS) can be used. Since these sensors have errors of different properties, they may be used while complementing each other with a plurality of sensors.

  FIG. 2 is a diagram illustrating an example of data stored in the facility data storage unit 12. The facility data storage unit 12 stores facility name, facility type, facility position, and facility detail data. Note that FIG. 2 is merely an example of data stored in the facility data storage unit 12, and data not shown in FIG. 2 can be stored in the facility data storage unit 12.

  The facility detection unit 14 has a function of detecting a facility on the traveling route of the vehicle. In the present embodiment, the guidance route set by the navigation device 28 is used as the traveling route of the vehicle, and facilities on the guidance route are detected. The facilities on the guide route may include not only facilities facing the guide route but also facilities located within a predetermined distance (for example, within 100 m) from the guide route. In the case where no guidance route is set in the navigation device 28, or when the navigation device 28 is not provided, a route corresponding to a road on which the vehicle is traveling may be used as the traveling route. Further, a route that is likely to be selected by the driver may be calculated from the past driving history of the driver as the traveling route.

  FIG. 3 is a diagram showing a configuration around the windshield 100 of the vehicle on which the peripheral information display device 1 according to the present embodiment is mounted. As shown in FIG. 3, the left and right sides of the windshield 100 have left and right support columns that support the windshield 100. This column is called “A-pillar”. A navigation device 28 is mounted on the center panel under the windshield 100. The navigation device 28 includes a monitor 30 and an operation unit 32.

  The image display unit 16 includes a left display device 18 provided on the left A pillar 102 and a right display device 20 provided on the right A pillar 104. The left display device 18 constitutes the left display area, and the right display device 20 constitutes the right display area. Thus, since the image display unit 16 has a display area around the visual field necessary for driving, the driver does not obstruct the visual field necessary for driving, and the driver during driving can move the display area with a small line of sight movement. Can see. In the following description, when the left display device 18 and the right display device 20 are collectively referred to, they are simply referred to as “display devices”.

  The right display device 20 and the left display device 18 have a touch panel function. The right display device 20 and the left display device 18 feed back data indicating the touch position to the display control unit 22.

  The display control unit 22 performs control so that a mark indicating the facility detected by the facility detection unit 14 is displayed on the image display unit 16. With reference to FIG. 4A and FIG. 4B, the display control by the display control unit 22 will be described in detail.

  4A is a diagram illustrating an example in which a mark indicating a facility is displayed on the left display device 18 and the right display device 20 under the control of the display control unit 22, and FIG. 4B is a diagram illustrating a travel route of the vehicle. It is.

  In FIG. 4 (a) and FIG. 4 (b), the facility mark indicates the type of facility. In the example shown in FIG. 4A, the coffee cup mark indicates “coffee shop” and the refueling machine mark indicates “gas station”. As shown in FIG. 4B, the traveling route R of the vehicle is set so as to go straight across the intersection from the current position P and turn right on the next right turn. On this traveling route R, coffee shops A and B can be seen on the left and right sides of the road, respectively. Here, an example in which the facility mark indicates the type of facility is described, but the facility type does not necessarily have to be the type of facility. For example, the target person of the facility (for families, for couples, etc.) You may display the mark which shows height.

  The display control unit 22 displays the facilities (here, coffee shops A and B) on the travel route R on the image display unit 16. As shown in FIG. 4A, the left display device 18 displays a mark indicating the coffee shop A on the left side of the road, and the right display device 20 displays a mark indicating the coffee shop B on the right side of the road. Further, the left display device 18 displays a mark indicating the gas station C that is not visible on the map but is on the traveling route R.

  As shown in FIG. 4A, the driver can grasp what kind of facility in a moment by expressing the type of facility on the display devices 16 and 18 with a simple mark. Although not shown, the facility mark may be colored. Thereby, the kind of facility can be grasped more easily.

  The vertical position of the facility mark displayed on each display device 18, 20 is determined according to the distance from the current position to each facility. As shown in FIG. 4A, the current position is displayed at the bottom of the display devices 18 and 20, and the display position of the facility mark is increased according to the distance from the current position. Thereby, the facility mark displayed on the left and right display devices 18 and 20 moves from top to bottom as the vehicle approaches the facility as the vehicle travels.

  Here, an example in which a facility far from the current position is displayed on the upper side of the display devices 18 and 20 is described, but conversely, the current position is displayed on the top of the display devices 18 and 20. The facility far from the current position may be displayed below the display devices 18 and 20. This configuration is suitable for a vehicle in which the A pillars 102 and 104 are inclined rearward. That is, when the A pillars 102 and 104 are inclined backward, the facility mark displayed on the display devices 18 and 20 moves from the bottom to the top and moves backward. As a result, the flow of scenery at the time of traveling coincides with the movement direction of the mark of the facility, and it is sensed that the user is approaching the facility.

  The display control unit 22 includes a facility selection unit 24 that obtains a facility selected based on data indicating the touch position fed back from the image display unit 16. When the data indicating the touch position is fed back from the image display unit 16, the facility selection unit 24 obtains the facility displayed at the touch position when the feedback is received, and determines that the facility has been selected.

  After obtaining the touched facility, the display control unit 22 reads the detailed information of the facility from the facility data storage unit 12 and transmits the read detailed information to the navigation device 28. The navigation device 28 displays the detailed information on the facility transmitted from the display control unit 22 on the monitor 30.

  FIG. 5 is a diagram showing an example in which detailed information is displayed on the monitor 30. The display control unit 22 highlights and displays the touched facility mark. “Highlighted display” means that the mark is displayed in a more prominent manner than other marks. For example, the touched facility mark may be displayed brighter than the other marks or blinked. Good. In FIG. 5, the selected facility (here, coffee shop B) is displayed brightly.

  The various setting units 26 have a function of receiving various setting information related to the display of facility data. The various setting units 26 may use the operation unit 32 of the navigation device 28 as hardware. In the present embodiment, the various setting units 26 receive the facility type, the number of facilities, and the display size. The various setting units 26 pass the input setting information to the display control unit 22, and the display control unit 22 controls the display of the facility mark on the image display unit 16 based on the setting information.

  When a facility type is input to the various setting units 26, the display control unit 22 selects a set type facility from the facilities detected by the facility detection unit 14, and images only the selected type of facility. It is displayed on the display unit 16. As the facility type input method, for example, a method of displaying facility type options on the monitor 30 and accepting a selection from the displayed options can be employed.

  By setting the facility type, only a desired type of facility can be displayed. Here, an example in which the display control unit 22 selects a set type of facility has been described. However, only the set type of facility is detected by the facility detection unit 14, and data of the detected facility is displayed on the display control unit 22. It is also possible to pass it on.

  When the number of facilities is input to the various setting units 26, the display control unit 22 displays the display on the screen display unit 16 so that the number of facilities displayed on the display devices 18 and 20 is equal to or less than the set number of facilities. Take control. In addition, as an input method of the number of facilities, a method of accepting an input with a numeric key of the operation unit 32 can be adopted.

  For example, when “3” is input as the number of facilities at a place where there is a coffee shop every 50 m on the travel route, the range from 400 to 400 m ahead of the current location is displayed as the range for displaying data of surrounding facilities as shown in FIG. Instead, the display range is up to 150 m ahead. By setting the number of facilities, it is possible to avoid a situation where an instantaneous determination is hindered by displaying many facility marks.

  When the display size is input to the various setting units 26, the display control unit 22 controls the size of the facility mark displayed on the left and right display devices 18 and 20 according to the input display size. As a method for inputting the display size, for example, the display size is displayed on the monitor 30 according to the rotation amount of the dial of the operation unit 32, and the display size displayed on the monitor 30 is input when the enter button is pressed. It is possible to adopt a method such as accepting as a value. By setting the display size, the facility mark can be displayed in a size that is easy for the driver to see.

  FIG. 6 is a flowchart showing the operation of the peripheral information display device 1 of the present embodiment. First, the peripheral information display device 1 accepts input of various setting values for facility marks displayed on the image display unit 16 at the various setting units 26 (S10), and passes the received setting values to the display control unit 22. . The display control unit 22 stores the set values passed from the various setting units 26 and displays the facility mark according to the set values.

  Next, the peripheral information display device 1 detects the current position of the vehicle at the current position detection unit 10 (S12). The peripheral information display device 1 searches for a facility on the travel route based on the preset guide route and the current position of the vehicle (S14). Next, the peripheral information display device 1 displays a mark indicating the found facility on the image display unit 16 based on the setting values input from the various setting units 26 (S16).

  The peripheral information display device 1 determines whether or not a touch input to the image display unit 16 is detected (S18). The touch input may be performed by a passenger sitting in the passenger seat. When the touch is not detected (NO in S18), the process returns to the process of detecting the current position of the vehicle (S12), the facility is searched again (S14), and the facility mark is displayed (S16) and displayed on the image display unit 16. Update facility mark.

  When a touch on the image display unit 16 is detected (YES in S18), the display control unit 22 specifies the facility touched from the touch position (S20). Subsequently, the peripheral information display device 1 highlights the specified facility and displays the detailed information of the facility on the monitor 30 of the navigation device 28 (S22). Thereafter, the peripheral information display device 1 returns to the process of detecting the current position of the vehicle (S12), and repeats the operation described above. In this case, the facility highlighted by touching is continuously highlighted when the display on the image display unit 16 is updated. The highlighting of the facility ends when another facility is touched, a predetermined time has elapsed, or the vehicle has passed the facility. The configuration and operation of the peripheral information display device 1 according to the first embodiment have been described above.

  In the peripheral information display device 1 according to the present embodiment, the facility on the right side of the road is displayed on the right display device 20 and the facility on the left side of the road is displayed on the left display device. Can understand.

  Further, the peripheral information display device 1 according to the present embodiment determines the position in the vertical direction of the display devices 18 and 20 according to the distance to the facility, and displays the facility mark at the determined position. At the same time, a facility mark flows from the top to the bottom of the display device. Therefore, the distance to the facility can be grasped intuitively. In addition, the facility mark moves in accordance with traveling, so that there is a feeling of traveling and it can be enjoyed as entertainment. This also has the effect of increasing the arousal level.

  The facility mark is displayed in a linear display area regardless of the position on the map. For example, referring to FIG. 4B, coffee shop A is on the straight line of the current vehicle direction, but coffee shop B is in the diagonally right direction of the current vehicle direction. Even in such a case, the facility mark is displayed as a function of the distance in the linear display area as shown in FIG. 4A, so that the distance to the facility on the traveling route can be easily understood. . Moreover, as shown to Fig.4 (a), the mark of the gas station C of 300 m ahead which is not displayed on the monitor 30 (refer FIG.4 (b)) of the navigation apparatus 28 is displayed. Thus, it is possible to know the facilities on the traveling route without changing the scale of the map displayed on the monitor 30.

  In addition, the peripheral information display device 1 according to the present embodiment displays the detailed information of the facility on the monitor 30 of the navigation device 28 by touching the facility displayed on the image display unit 16. Detailed information on a certain facility can be easily acquired, and can be used for determining whether or not to stop at a facility.

  In addition, since the peripheral information display device 1 of the present embodiment is provided with a display device in the A pillars 102 and 104, the driver and the passenger can share the same information. As a result, communication between the driver and passengers can be facilitated and conversation can be expected.

  In the above-described embodiment, the example in which the display devices 18 and 20 are provided on the left and right A pillars 102 and 104 of the windshield 100 has been described. However, in addition to the left and right A pillars 102 and 104, as shown in FIG. The upper display device 34 may be provided on the upper side of the windshield 100, and the lower display device 36 may be provided on the lower side. In this configuration, the left half of the upper display device 34 and the lower display device 36 and the left display device 18 constitute a left display area, and the right half and the right display device 20 of the upper display device 34 and the lower display device 36. And constitute the right display area. Thus, by providing the display devices 34 and 36 not only on the left and right A pillars 102 and 104 but also on the upper and lower regions of the windshield 100, the display region can be enlarged without obstructing the visual field required for driving.
