Further, the peripheral circuit 21 is provided with an on / off control circuit (not shown) for the getting-off notification switch, which controls the getting-off notification switch.

  The bus navigation apparatus 10 includes a GPS function in addition to a conventional automatic guidance broadcast control function by a door opening / closing detection unit 16 that detects a door signal and a vehicle speed detection unit 27 that detects a vehicle speed pulse. As a result, it is possible to determine the travel direction from the coordinate database (latitude and longitude) that serves as the operation base point for bus stops, intersections, garages, and roundabouts, and the destination, and vector data for the travel direction is added. By mounting, the operation position of the bus 100 is grasped.

FIG. 2 shows an aspect in the case where the passenger 100 re-gets on and off the bus 100 immediately after leaving the bus stop 43.
The stop coordinate area 41 is a range on the map data belonging to the bus stop 43. The stop coordinate area 41 is determined for every bus stop on the bus 100, and the range is set when the map database 35a is created and stored together with the map data. The bus navigation device 10 specifies the current position of the bus 100 when the absolute position / azimuth detection unit 23 receives the GPS modulation signal transmitted from the GPS satellite 40, and based on the map data stored in the map database 35a. The stop coordinate area 41 to which the

  When the bus navigation apparatus 10 detects that the entrance / exit door is opened by the door opening / closing detection unit 16 in the stop coordinate area 41, if this detection is the first in the same stop coordinate area 41, the bus stop guidance broadcast It is the second time to detect the opening of the entrance / exit when the entrance / exit is opened or closed to update the content of the next bus stop guidance broadcast and get on and off the delayed passenger 42 If this is the case, the contents of the bus stop guidance broadcast will not be updated. In addition, when it is detected that the entrance / exit door is opened for the second time or later, and after the guidance broadcast of the next bus stop 43 is started, the content of the guidance broadcast is rewound to the initial position, and the entrance / exit door is opened. After closing, the next bus stop will be broadcast again.

  In addition, a passenger gets a get-off notification by pressing a get-off notification button (not shown) that is pressed when the passenger intends to get off at the next bus stop 43. Although this getting-off notification is canceled when the getting-on / off door is opened, the bus navigation apparatus 10 can restrict the releasing of the getting-off notification in accordance with the opening / closing frequency of the getting-on / off door in the same stop coordinate area 41. .

  The same applies when the bus 100 departs from the bus stop 43 and the exit / opening / closing door is opened and closed again within the same stop coordinate area 41 as the bus stop 43 immediately after the next bus stop 43 is notified of getting off. No matter how many times the door opening / closing detection unit 16 detects the opening / closing of the entrance / exit in the stop coordinate area 41, the getting-off notification unit 14 restricts the release of the getting-off notification until the bus 100 goes out of the stop coordinate area 41. In such a case, even when the opening / closing of the entrance / exit door is detected, the notification of getting off the vehicle cannot be canceled.

FIG. 3 shows an operation sequence of the bus 100, and shows a period from when the bus 100 being operated stops at the bus stop 43 until it operates again.
Step S1 is a state in which the bus 100 is traveling. At this time, the getting-off notification lamp is lit, and the getting-off notification is made.
The traveling bus 100 stops at the bus stop 43 (step S2).

  When the bus 100 stops at the bus stop 43, the passenger door is opened (step S3). At the same time that the passenger door is opened, the getting-off notification is canceled and the getting-off notification lamp is turned off. In addition, a destination guidance broadcast flows outside the bus 100 and passengers get on and off.

  When the passengers get on and off, the bus driver closes the passenger door (step S4) and departs the bus 100 (step S5).

  When the bus 100 departs, in conjunction with the vehicle speed pulse, the bus navigation device 10 broadcasts the next bus stop in the bus 100 (step S6).

  If there is a passenger who listens to the next bus stop guidance broadcast and wishes to get off at the next bus stop, this passenger presses the get-off notification button and the get-off notification lamp lights up, so that the getting-off notification is made. Is done.

  At this time, when there is no passenger 42 who missed the bus 100 (step S7: NO), the bus 100 continues to travel toward the next bus stop.

  However, if there is a passenger 42 who has missed the bus 100 before the bus 100 leaves the stop coordinate area 41 (step S7: YES), the bus driver stops the bus 100 (step S9).

  When the bus driver stops the bus 100 and opens the entry / exit door (step S9), the passenger 42 who gets late is getting on and off. At this time, since the bus 100 is located in the same stop coordinate area 41 as the bus stop 43 where the boarding / exiting was performed earlier, the bus navigation device 10 does not cancel the getting-off notification even when the boarding door opens, and the next bus stop guidance broadcast Rewind the contents.

  When the passenger 42 who got late has finished getting on and off, the bus driver closes the passenger door (step S10) and departs the bus 100 (step S11).

  When the bus 100 departs toward the next bus stop 43, the bus navigation apparatus 10 performs guidance broadcasting of the next bus stop again in the bus 100 in conjunction with the vehicle speed pulse (step S12).

  At this time, the passenger can press the get-off notification button to make a get-off notification. However, if the get-off notification is made in step S7, the get-off notification lamp remains on, so the passenger gets off again. There is no need to press the notification button.

FIG. 4 shows a flowchart of specific operations of the bus navigation apparatus 10.
First, the case where the bus 100 opens the passenger door for the first time in the stop coordinate area 41 (when the processing from step S3 to step S6 shown in FIG. 3 is performed) will be described.

  First, the control unit 11 determines whether or not the passenger door is opened (step S21). At this time, if the controller 11 determines that the passenger door is not open (step S21: NO), the process of step S21 is repeated until the controller 11 determines that the passenger door is opened.

  However, when the control unit 11 determines in step S21 that the passenger door has been opened (step S21: YES), the control unit 11 detects the current position detected via the absolute position and direction detection unit 23 (step S22).

  When detecting the current position, the control unit 11 next determines whether or not the current position is the same stop coordinate area 41 as the stop coordinate area 41 that opened the previous entry door (step S23). At this time, if the control unit 11 determines that the current position is a stop coordinate area 41 that is different from the stop coordinate area 41 that opened the previous door (step S23: NO), the control unit 11 cancels the getting-off notification ( In step S24), the content of the guidance broadcast is updated to the content of the next bus stop guidance broadcast (step S25).

  When the content of the guidance broadcast is updated to the content of the next bus stop guidance broadcast in step S25, the control unit 11 performs a destination guidance broadcast outside the vehicle (step S26).

  When the control unit 11 detects the vehicle speed pulse via the vehicle speed detection unit 27 after performing the destination guidance broadcast and closing the passenger door (step S27), the control unit 11 performs the guidance broadcast of the next bus stop in the vehicle (step S28).

  Next, the case where the bus 100 opens the passenger door for the second time or later in the stop coordinate area 41 (when the processing from step S8 to step S12 shown in FIG. 3 is performed) will be described.

  First, the control unit 11 determines whether or not the passenger door is opened (step S21). At this time, if the controller 11 determines that the passenger door is not open (step S21: NO), the process of step S21 is repeated until the controller 11 determines that the passenger door is opened.

  However, when the control unit 11 determines in step S21 that the passenger door has been opened (step S21: YES), the control unit 11 detects the current position detected via the absolute position and direction detection unit 23 (step S22).

  In step S23, when the control unit 11 determines that the current position is the same stop coordinate area 41 as the stop coordinate area 41 that opened the previous door (step S23: YES), the control unit 11 guides the next bus stop. The broadcast is rewound (step S29).

  When the control section 11 rewinds the guidance broadcast at the next bus stop, the control section 11 performs the destination guidance broadcast outside the vehicle (step S26).

  When the controller 11 detects the vehicle speed pulse via the vehicle speed detector 27 after performing the destination guidance broadcast (step S27), the controller 11 broadcasts the next bus stop in the vehicle (step S28).

  As described above, the bus navigation apparatus 10 is provided with the stop coordinate area 41, and the same is obtained by dividing the stop coordinate area 41 between when the door is opened for the first time and when it is opened for the second time or later. Even when the passenger door is opened and closed again for passengers getting on and off at the bus stop, it is not necessary to adjust the guidance broadcast by the driver's manual operation and to re-operate the getting-off button by the passenger.

  As mentioned above, although this invention was demonstrated based on one Embodiment, this invention is not limited to this. For example, in this embodiment, the bus stop is updated and the getting-off notification is canceled when the passenger door is opened, but the present invention is not limited to this, and the passenger door may be closed.
