  When a CD-ROM in which map data is recorded as data is set in the CD-ROM control unit 33, the main CPU 19 stores the read map data in the map database 35a.

  When a CD-ROM in which operation schedule data is recorded as data is set in the CD-ROM control unit 33, the main CPU 19 stores the read operation schedule data in the SRAM 31c. The operation schedule data is data indicating an operation schedule, and the operation schedule is a table indicating a time at which the bus is scheduled to pass a predetermined position. More specifically, the operation schedule is a table in which the position of each bus stop as a predetermined position is associated with the scheduled passage time (departure scheduled time or scheduled arrival time) of the bus at each bus stop.

  When the CD-ROM in which the operation route data indicating the bus operation route is recorded as data is set in the CD-ROM control unit 33, the main CPU 19 stores the read operation route data in the SRAM 31c.

  In the first embodiment, the main CPU 19 reads the map data around the own bus read from the map database 35a, the calculated current position and traveling direction of the own bus, operation schedule data and operation route data stored in advance in the SRAM 31c, and Image data is generated based on the current time input from the peripheral circuit 21, and an image signal indicating the image data is output to the display unit 15. That is, the main CPU 19 displays an image on the display unit 15 by outputting an image signal to the display unit 15.

  Hereinafter, the display control operation of the main CPU 19 will be specifically described. FIG. 3 is an explanatory diagram illustrating an example of display on the display unit 15.

  When the input unit 17 is operated, the main CPU 19 of the control unit 11 displays the map M around the own bus on the display unit 15 as shown in FIG.

  Further, the main CPU 19 of the control unit 11 displays the operation route display R indicating the operation route of the bus on the map M in a mode different from other road displays based on the operation route data stored in advance in the SRAM 31c. This is displayed on the unit 15. Specifically, the operation route display R is displayed in a color or pattern different from other road displays. Thereby, the bus driver can visually determine the bus operation route visually on the map M displayed on the display unit 15.

  Further, the main CPU 19 displays a current position marker X indicating the current position of the own bus on the map M displayed on the display unit 15 and also plans to pass the own bus at the current time on the operation route of the own bus. The planned position marker Y indicating the planned position to be displayed is displayed.

  Specifically, the main CPU 19 displays the current position marker X on the map M based on the calculated current position and traveling direction of the own bus. Further, the main CPU 19 obtains the current planned position in the operation route based on the current time input from the peripheral circuit 21 and the operation schedule data stored in advance in the SRAM 31c, and displays the planned position marker Y indicating the planned position. It is displayed on the map M.

  The operation for obtaining the current planned position in the operation route will be described in detail. In the main CPU 19, the scheduled passage time of the bus stop that is scheduled to pass recently in the operation schedule data and the next in the operation schedule data are scheduled to pass. The current planned position at the current time is calculated from the scheduled passage time of the bus stop and the distance between the two bus stops.

  The operation for obtaining the current planned position in the operation route will be described in detail. The main CPU 19 passes the scheduled time of passage of the bus stop that the bus has recently passed and the passage of the bus stop that the bus is scheduled to pass next. The current planned position at the current time is calculated from the scheduled time and the distance between the two bus stops. The scheduled passage time of the bus stop that the bus is scheduled to pass recently and the scheduled passage time of the bus stop that the bus is scheduled to pass next are extracted from the operation schedule data stored in the SRAM 31c.

  Here, the operation schedule includes the position of each bus stop as a predetermined position, a plurality of positions along the operation route between two adjacent bus stops, and the scheduled passage time when the bus passes through these positions. An associated table may be used. As a result, the main CPU 19 refers to this table and extracts the position corresponding to the scheduled passage time that coincides with the current time as the current scheduled position in the operating route, thereby obtaining the planned position in the operating route of the bus. it can.

  The map M displayed on the display unit 15 is set to a scale capable of displaying the current position marker X and the planned position marker Y. That is, the scale of the map M displayed on the display unit 15 is set by the main CPU 19 according to the distance between the current position and the planned position. As a result, when the distance between the current position and the planned position is widened (or contracted), the scale is changed and the current position marker X and the planned position marker Y are displayed.

  Further, when the current time is before the operation start time, the planned position marker Y is displayed at the start point portion in the operation route display R, and when the current time is after the operation start time, the planned position marker Y is As shown, it is displayed corresponding to the planned position. Further, when the current time is after the operation end time, the planned position marker Y is displayed at the end point portion in the operation route display R. Here, the operation end time is the time when the bus is scheduled to arrive at the first bus stop on the operation route. The current position marker X and the planned position marker Y are displayed as isosceles triangles, and the apex angle indicates the traveling direction of the own bus.

  The current position marker X is set to be the center (or substantially the center) in the map M. As a result, the bus driver can instantaneously determine the current position at a glance, and can also instantaneously determine the planned position for the current position of the own bus.

  As described above, according to the first embodiment, the current position marker X indicating the current position of the bus and the planned position marker Y indicating the planned position of the bus are displayed on the map M displayed on the display unit 15. The bus driver can instantly determine the difference between the current position of the bus and the planned position of the bus at a glance. Thus, the bus driver can concentrate more on driving the bus.

  Here, in the first embodiment, the main CPU 19 displays the current position marker X indicating the current position of the bus and the planned position marker Y indicating the expected position of the bus on the display unit 15 with different display modes. Yes. Specifically, the display colors or patterns of the markers X and Y are displayed on the display unit 15 differently. Therefore, the bus driver can instantly determine at a glance how late the bus is operating with respect to the operating schedule or how far the bus is operating. Thus, the bus driver can concentrate more on driving the bus.

[2] Second Embodiment The second embodiment is different from the first embodiment in that the display mode of the section between the current position and the planned position on the bus route is the display mode of the remaining sections. Unlike the above, the operation route is displayed on the map. FIG. 4 is an explanatory diagram showing an example of display on the display unit 15 when the current position of the bus is delayed with respect to the planned position. FIG. 5 is an explanatory diagram showing an example of display on the display unit 15 when the current position of the bus is ahead of the planned position. Hereinafter, in this 2nd Embodiment, the part similar to the said 1st Embodiment attaches | subjects the same code | symbol, and abbreviate | omits description.

  As shown in FIGS. 4 and 5, the main CPU 19 changes the display mode of the section S1 between the current position marker X and the planned position marker Y on the operation route display R indicating the bus operation route, to the remaining section S2. Is different from the display mode.

  Specifically, in the second embodiment, the main CPU 19 displays the section S1 as red or blue and the section S2 as white. As a result, the bus driver can instantly determine the difference between the current position of the bus and the planned position of the bus at a glance.

  Furthermore, in the second embodiment, the main CPU 19 changes the display mode of the section S1 indicated by the current position marker X and the planned position marker Y according to the relationship of the current position of the bus to the planned position of the bus. Yes.

  That is, the main CPU 19 determines whether the current position of the bus is delayed or advanced with respect to the planned position on the operation route as the relationship of the current position of the bus to the planned position of the bus. The main CPU 19 changes the display mode of the section S1 indicated by the current position marker X and the planned position marker Y according to whether the current position of the bus is delayed or advanced with respect to the planned position on the operation route. I am letting.

  Specifically, when the current position of the bus is delayed with respect to the planned position on the operation route (FIG. 4), the main CPU 19 displays the section S1 in red, and the current position of the bus becomes the planned position on the operation route. On the other hand, when proceeding (FIG. 5), the main CPU 19 displays the section S1 in blue. As a result, the bus driver can instantly determine at a glance how late or advanced the bus is operating. Therefore, the bus driver can concentrate more on the bus operation.

  Note that the display color of the section S1 may be changed according to the distance between the current position and the planned position. For example, the display color of the section S1 may be changed to become darker as the distance between the current position and the planned position increases. In other words, the display color of the section S1 may be changed so that the display color becomes lighter as the distance between the current position and the planned position decreases. As a result, the bus driver can more effectively and instantaneously determine how late or advanced the bus is operating.

  As mentioned above, although this invention was demonstrated based on one Embodiment, this invention is not limited to this.

  For example, in the above embodiment, the current position marker and the planned position marker are displayed as isosceles triangles, and the display color or pattern of each marker is different. However, the display mode of each marker is not limited to this. Any display mode may be used as long as the driver can distinguish between the current position marker and the planned position marker. For example, the current position marker may be displayed as an isosceles triangle and the planned position marker may be displayed as a circle.

  In the above embodiment, the case where the control program is stored in the ROM has been described. However, the control program is recorded in advance on a recording medium such as various magnetic disks, optical disks, and memory cards, read from these recording media, and installed. It is also possible to configure so as to. It is also possible to provide a communication interface, download the control program via a network such as the Internet or a LAN, install and execute the control program.
