  However, the conventional destination display device disclosed in Patent Document 1 has a limited number of LED elements, and when a display including information on a plurality of points is to be performed, the number of characters to be displayed simultaneously is increased. There was a risk that it would be difficult for the passengers to see the size.

  Similarly, an electro-optical display device that has a display unit in which LEDs are arranged in a matrix and is used for news distribution in a train or public space has been conventionally known. In such an electro-optical display device, the number of characters that can be displayed is increased by preventing the characters from becoming smaller by changing the display content by animation or scrolling.

  However, in the destination indicator, if the display is switched during driving, the driver of the oncoming vehicle may be visually obscured by the change in the light emission state, which may cause danger. The display of is required to continue in a certain manner. For this reason, the amount of information displayed by the destination display device is restricted, and there is a possibility that it may interfere with providing necessary information to the passengers.

  In view of the above circumstances, an object of the present invention is to provide a destination display system capable of performing guidance display that allows a passenger to easily understand route information.

  The present invention provides a “display device capable of displaying various display modes related to a destination of a vehicle, a storage unit that holds specific point information about a waypoint or a destination point that is a specific point on a route on which the vehicle travels, and a storage unit A control unit that controls the display device with reference to information including the specific point information held by the control unit, and the control unit causes the display device to display a first display mode mainly related to the destination point while the vehicle is traveling. In the destination display system, the second display mode including the specific point information of the specific point located in front of the route is displayed on the display device according to the staying point of the vehicle while the vehicle is stopped. is there.

  According to the destination display system of the present invention, the display device continuously displays the destination point while the vehicle is traveling, but when the vehicle stops at a stop or the like, the vehicle is changed according to the staying point of the vehicle, that is, the stop. The display device displays a second display mode including specific point information such as a waypoint located in front of the traveling route, so that it is easy for passengers waiting for the vehicle at the stop to know the route information of the vehicle that has arrived. A guidance display can be performed.

  The destination display system of the present invention further includes a door opening / closing detection unit that transmits a door opening signal indicating that the vehicle door is opened and a door closing signal indicating that the door is closed to the control unit. And the control unit may determine that the vehicle is stopped by receiving the door opening signal and determine that the vehicle has started traveling by receiving the door closing signal.

  According to this configuration, since the display mode of the display device is switched based on the opening / closing of the passenger door, it is possible to reliably switch the display mode during traveling and when the vehicle is stopped.

  Furthermore, the destination display system of the present invention may be “the second display mode is a display mode in which information on a destination point and specific point information are alternately displayed”.

  According to this configuration, when the vehicle is stopped, information about the destination point and information about the waypoint are displayed alternately, so that it is possible to display easily without reducing the display of characters and the like on the display device. it can. .

  Further, the destination display system of the present invention may be “both position acquisition means acquire vehicle position information from a satellite positioning system and specify stay point information based on the vehicle position information”.

  According to this configuration, since the staying point information can be specified by using the satellite positioning system, it is possible to update the staying point information with high accuracy without any operation by the crew.

  Furthermore, the destination display system of the present invention may be “the vehicle position acquisition unit includes a stay point update unit that updates the stay point information according to the operation of the crew”.

  According to this configuration, since the crew member can update the staying point information as needed according to the traveling situation, the destination display system can be flexibly operated. That is, appropriate display can be performed even when the satellite positioning system does not operate well due to radio interference or when the satellite positioning system cannot properly update the staying point information because the stop interval is narrow. In addition, since the staying point information can be updated at any time without a satellite positioning system, the system can be simplified. Here, as an example of the stay point update means of this configuration, an operation panel that updates the stay point information according to the operation of the crew can be cited.

  As described above, according to the present invention, since it is possible to easily display the waypoints on the route on which the vehicle travels at the stop, it is possible to display a destination that allows the passenger to easily obtain route information. A system can be provided.

The night signal device 83 sends a night signal to the interface device 50 for determining whether it is daytime or nighttime. Switching between day and night is set by a timer in this example. Here, the door opening / closing detection device 81 corresponds to the door opening / closing detection unit of the present invention.

  The emergency signal device 84 is activated when the crew member operates the emergency button, and transmits an emergency signal to the interface device 50. When receiving the emergency signal, the interface device 50 displays a display mode indicating the occurrence of an emergency on the destination display 10, the side display 12, and the back display 14.

  A satellite positioning device 90 is further connected to the interface device 50. The satellite positioning device 90 functions as an in-vehicle transmission / reception device of the satellite positioning system, receives data obtained by measuring the current position of the bus B from the satellite, more precisely, the position of the satellite positioning device 90, and the interface device 50. Send to. The control unit 30 that has acquired the current position information of the bus B, that is, the vehicle position information, via the interface device 50 updates the staying point information of the bus B based on the vehicle position information. Here, the satellite positioning device 90 corresponds to the vehicle position acquisition means of the present invention.

Hereinafter, the operation of the present invention when the bus B is operated will be described.
Bus B travels along route R shown in FIG. In the operation route R of this example, the starting point is “Gifu” and the destination point is “Ogaki”.

  When setting information regarding the operation route of the bus B, the memory device 60 is connected to a computer terminal of an operation management system such as a business office, and operation data is written into the memory device 60. In addition, the operation data can be used in the destination display system 1 by connecting the memory device 60 to the interface device 50 of the bus B.

  In this example, the staying point information of the traveling bus B that is running or stopped is received by the satellite positioning system, and the control unit 30 specifies the staying point information based on the vehicle position information. To do.

  On the route R, there are nine stops between the starting point “Gifu” and the destination point “Ogaki”. The stops are "Kano", "Rokujo", "Prefectural Office", "Gidai", "Hozumi", "Ushimaki", "Miki Park", "General Government Building" and "Ogaki Park" in order from the side closest to "Gifu".

  As shown in examples in FIGS. 4A to 4D, the display device 20 displays various display modes based on the control of the control unit 30. FIG. 4A shows an example of a display mode during traveling, and FIGS. 4B to 4D show examples of display at a stop on the way from the starting point to the destination point. .

  FIG. 4A shows a display mode 20a when the bus B is traveling between “Gifu” and “Kano”. At this time, the system number “3” is displayed on the left side of the screen of the display device 20, and “Ogaki” indicating the destination point is displayed in the center. In the upper part, “via prefectural office” indicating the waypoint is displayed in small size. In the lower part, “For Ogaki” and “Via Kentyo-mae” are displayed in small sizes as English display.

  FIG. 4B and FIG. 4C are examples of display when the bus B is stopped at the stop “Kano”. FIG. 4B shows a state where “To Ogaki” indicating the destination point is displayed, and FIG. 4C shows a state where “Via prefectural office” indicating the way point is displayed.

  FIG. 5 is a route information table 62 schematically showing the operation route R as an example of the route information table. In the route information table 62, the stay point information C of the bus B and the specific point information S are stored in association with each other. The specific point information S is information for conveying the outline of the route on which the bus B travels to the passengers, and includes the names of via points and destination points. In this example, the destination point is “Ogaki”, and the waypoints are “Prefectural Office” and “Miki Park”. In the route information table 62, the stay point information C corresponding to the stay point of the bus B and the specific point information S located in front of the bus B with respect to the stay point are associated. For example, while the bus B is stopped at “Kano”, as shown in FIG. 5, the stay point information C is “Kano” and the specific point information S is “Prefectural Office”.

  When the bus B stops at the stop “Kano” and the door D1 or D2 is opened, a door opening signal is transmitted from the door opening / closing detection device 81 to the control unit 30 via the interface device 50. The control unit 30 controls the display device 20 to perform display in the second display mode for stopping. Based on the command from the control unit 30, the display device 20 displays “to Ogaki” of the destination point shown in FIG. 4B as the first pattern 20 b, and after the predetermined time has elapsed (for example, after 5 seconds), As the pattern 20c, “via prefectural office” shown in FIG. 4C is displayed. The control unit 30 displays the second pattern 20c and switches the display of the display device 20 to the first pattern 20b again after a predetermined time (for example, 5 seconds) has elapsed. Thereafter, the same display switching is repeated to alternately display the destination point and the waypoint at predetermined time intervals.

  Then, when the crew member performs an operation of closing the passenger door D1 or D2 that has been opened, a door closing signal is input to the control unit 30 from the door opening / closing detection device 81 via the interface device 50. The display device 20 is controlled to switch from the second display mode for stopping to the first display mode for traveling. When the entrance / exit door D1 or D2 is closed and the bus B starts to travel, the satellite positioning device 90 recognizes the change in the position of the bus B and moves to the control unit 30 via the interface device 50 as the bus B moves. The updated vehicle position information is transmitted. Based on the update of the vehicle position information, the control unit 30 updates the stay point information from “Kano” to “Rokujo”. The specific point information S corresponding to “Rojo” of the stay point information C is “in front of the prefectural office” in the same manner as “Kano”. Since the control unit 30 performs display control for traveling, the display device 20 displays “Ogaki bound” which is the first display mode illustrated in FIG.

  The satellite positioning device 90 notifies the interface device 50 of the occurrence of an error when an error occurs, such as when the radio wave condition is poor due to the influence of the surrounding environment. When the notification of the occurrence of the error is received, the interface device 50 performs a display for notifying the malfunction of the satellite positioning system on a crew member display device (not shown). In such a case, the crew member operates the operation panel 70 to manually update the staying point information C. Specifically, the stay point information C is updated to “Rokujo”, which is the next stop after “Kano”, by operating the buttons on the operation panel 70 or the like. And since the control part 30 performs display control for driving | running | working, "Ogaki bound" is displayed on the display apparatus 20. FIG.

  When arriving at the next stop “Rokujo”, the stay point information C of the bus B is “Rokujo”, and the display device 20 displays “To Ogaki”. According to the route information table 62, since the specific point information S corresponding to “Rokujo” of the stay point information C is “Prefectural Office”, the bus B stops at the “Rokujo” stop and the entrance D1 or D2 is opened. When the opening operation is performed, the control unit 30 starts the stop display control, and the display device 20 alternately displays “to Ogaki” in the display pattern 20b and “via prefectural office” in the display pattern 20c. Two display modes are displayed. When the bus B departs from the “Rokujo” stop, the control of the display device 20 by the control unit 30 is running from the stopped display control according to the door closing signal operated by the crew as in the case of “Kano”. Switching to display control, the staying point information C is updated to “prefectural office”, which is the next stop, by input from the satellite positioning device 90 or operation of the operation panel 70. At this time, the specific point information S corresponding to “Prefectural Office” as the stay point information C is “Mishiro Park” as shown in the route information table 62.

  When the bus B arrives at the stop “Prefectural Office” and stops, the entrance D1 or D2 is opened, and the display control of the display device 20 is switched to the display control during the stop, the display device 20 has the first pattern 20b. “To Ogaki” and “via Sanjo Park” are alternately displayed as the second pattern 20d. In other words, passengers who are going to get on the bus B at the stop “Prefectural Office” are informed that the waypoint to the destination point “Ogaki” is “Miki Park”. Thereby, even if the passenger does not know the details of the route on which the bus B operates in advance, the passenger can know which area the bus B passes through. In addition, even if there are multiple bus routes that run from the bus stop “Prefectural Office” to the destination “Ogaki”, passengers will be able to choose the routes that the currently stopped bus B will run toward the destination. It can be easily distinguished from the route of the street.

  When the bus B further travels on the route and passes the stop “Ushimaki”, the specific point information S becomes “Ogaki” which is the destination point. When arriving at the stop “Mishiro Park” and opening the passenger door D1 or D2, the display device 20 continuously displays the first pattern 20b shown in FIG. This is because the display of the second pattern becomes the same as the first pattern 20b because the specific point information S indicates the destination point.

  As described above, according to the destination display system 1 of the present embodiment, the display device 20 continuously displays the destination point while the bus B is traveling. However, when the bus B stops at a stop or the like, the bus B The display device 20 is caused to display a second display mode in which specific point information S such as a waypoint located in front of the route on which the bus B travels and a destination point are alternately displayed according to the staying point of the vehicle, that is, the stop. Therefore, it is possible for the passenger waiting for the bus at the bus stop to perform guidance display that makes it easy to grasp the route information of the bus that arrived.

  In addition, according to the destination display system 1 of the present embodiment, the display mode of the display device 20 is switched based on the opening / closing of the passenger doors D1 and D2, so the switching of the display mode during traveling and stopping is ensured. It can be carried out.

  Furthermore, according to the destination display system 1 of the present embodiment, when the bus B is stopped, the information about the destination point and the information about the waypoint are displayed alternately. It is possible to perform easy-to-see display without doing so.

  In addition, according to the destination display system 1 of the present embodiment, the staying point information C can be specified using the satellite positioning system, so that it is possible to update the staying point information C with high accuracy without any operation by the crew. it can.

  Furthermore, according to the destination display system 1 of the present embodiment, the crew member can operate the operation panel 70 according to the situation and update the staying point information C as needed, so that flexible operation can be performed. In other words, even if the satellite positioning system does not operate well due to radio interference due to the influence of the building, etc., or if the satellite positioning system cannot properly update the staying point information C because the stop interval is narrow, it is supplemented by the crew's operation. By doing so, an appropriate display can be performed. Further, since the staying point information C can be updated at any time without a satellite positioning system, the system can be simplified by omitting the satellite positioning device 90.

  By the way, if there is no display of the second display mode alternately showing the destination point and the specific point as in this example, and the display pattern 20a is still displayed on the display device 20 as in the past, Even if the passenger who tries to get on the bus with “Kano” can see “Go to Ogaki” on the display device 20, the smaller “In front of the prefectural office” may not be visible. Therefore, if you do not know that there are multiple bus routes, you may accidentally get on a bus traveling on a route different from the route you originally intended to get on. Even if it is known that there are a plurality of routes, it is difficult for the passenger to determine whether or not the bus B is to be ridden if “via prefectural office” cannot be read.

  In addition, even if the point name of the waypoint is displayed as shown in FIG. 4C while stopping at the stop, if the destination point is not “Ogaki” at the same time, the passenger will It's inconvenient because you don't know the route to go ahead.

  On the other hand, if the destination point “Ogaki” and the route point “Prefectural Office” are displayed together on the destination display, the characters become smaller due to restrictions on the size of the display area and the number of pixels, and overall visibility is reduced. There is a fear. Also, for passengers boarding bus B at a stop after “Prefectural Office”, it is inconvenient as if only the destination point “Ogaki” is displayed when the information of the waypoint “Prefectural Office” is displayed. Become.

  In response to the problem of the conventional destination indicator as described above, according to the destination display system 1 of the present example, the waypoints and destination points on the route on which the bus B travels are displayed in large letters in an easy-to-read manner at each stop. Therefore, it is possible to perform guidance display that makes it easy for passengers to grasp route information.

  In addition, embodiment of this invention is not limited to said structure, As shown below, it can change variously.

  In the above embodiment, the control unit 30 includes a CPU and various memories, but is not limited thereto. For example, the control unit 30 does not include a CPU and various memories. Alternatively, the display device 20 may be simply driven by receiving a control signal from the interface device 50 or another external device. Moreover, the control part 30 is not limited to what is built in the destination indicator 10, and may be provided outside the destination indicator 10.

  Moreover, although said embodiment showed what the staying point information of the bus | bath B was updated by the satellite positioning system, it is not limited to this. For example, the staying point information may be updated in accordance with an input from the operation panel 70 operated by the crew without using the satellite positioning system. When the bus B departs after passengers get on and off at the bus stop, the crew always performs an operation on the operation panel 70 to update the operation information. For example, an operation of pressing a frame advance button (not shown) to update the stop information is performed. When the control unit 30 receives the operation signal for updating the stop information via the interface device 50 connected to the operation panel 70, the control unit 30 updates the stay point information.

  In the above-described embodiment, the door opening / closing detection device 81 is configured to send a door opening signal and a door closing signal to the interface device 50 in response to opening / closing of the passenger door D1 or D2. A signal may be sent for only one of the operations. When only the door opening signal is sent at the time of opening, the interface device 50 recognizes that the passenger door D is closed when there is no door opening signal. On the other hand, when only the door closing signal is sent at the time of closing, the interface device 50 recognizes that the passenger door D is opened when there is no door closing signal. Thereby, the control system based on opening / closing of a passenger door can be simplified.

  In the above embodiment, the door opening signal and the door closing signal are sent to the interface device 50 according to the opening / closing of the entrance doors D1 and D2, but the present invention is not limited to this. A signal may be sent to open / close only one of D2. In the case of detecting the opening / closing of both of the passenger doors D1, D2, the state of the bus based on the opening / closing of the door becomes more reliable, and therefore the display control accuracy of the display device 20 can be improved. On the other hand, in the case of detecting the opening / closing of only one of the passenger doors D1 and D2, devices for detecting the opening / closing of the other passenger door are not required, and thus the configuration can be simplified.

  In the above embodiment, the operation panel 70 is provided separately from the interface device 50. However, the interface device 50 and the operation panel 70 may be integrally configured. For example, the interface device 50 may be incorporated in the casing of the operation panel 70, or the operation panel 70 and the interface device 50 may be configured to share a substrate or other components.

  About the technical idea which can be grasped | ascertained from the structure of embodiment of this invention, it adds to the following with those effects.
