Hereinafter, examples of embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing an example of an outline of guidance processing of the in-vehicle device 1 for a bus. The in-vehicle device 1 for a bus is a computer device mounted on the bus B. The vehicle-mounted device 1 for a bus may be a part of a navigation device that provides route information to a driver, for example.

Bus B is a so-called fixed-route bus, and travels on a predetermined route. Bus B sequentially stops at a plurality of stops installed on the route. Regarding a stop where there are no customers getting off or getting on, bus B may pass without stopping, but for convenience, bus B will be described as stopping. "Stop at a bus stop" includes "passing through a bus stop".

FIG. 1A is a schematic diagram for explaining an example of guidance processing of the in-vehicle device 1 for a bus. The vehicle-mounted device 1 for a bus has a GPS receiving device and can acquire the current position of the bus B. In the present embodiment, the in-vehicle device 1 for a bus manages each stop in association with a route passage detection area and a stop detection area.

When the bus B enters the route passage detection area, the in-vehicle device 1 for the bus identifies a stop associated with the route passage detection area, and outputs a voice indicating arrival guidance information indicating that the bus B will arrive at the stop soon. Flush inside. The vehicle-mounted device 1 for a bus may display arrival guidance information indicating that the vehicle will arrive at the bus stop on the display device in the bus B.

After that, when the bus B passes through the stop detection area, the in-vehicle device 1 for the bus refers to the stop information stored in the in-vehicle device 1 for the bus in advance, and stops at the stops existing on the route in the correct stop order. Judge whether or not. Further, the in-vehicle device 1 for a bus determines whether or not the route passage detection area entered before arriving at the stop and the passed stop detection area are associated with a common stop.

If bus B stops in the correct stop order according to the stop information, and the route passage detection area and the stop detection area that have passed are associated with a common stop, bus B will take the regular route to the stop and the stop. It is judged that the bus stopped at. When the bus B exits the stop detection area, the in-vehicle device 1 for the bus outputs a voice indicating the next stop guidance information for guiding the next stop.

In FIG. 1A, when the bus B travels in the direction of the arrow (to the right in the figure), it first passes through the stop detection area 201b. Since the bus B does not pass through the route passage detection area 202b corresponding to the stop detection area 201b, the guidance information is not output when the bus B passes through the stop detection area 201b.

After that, the bus B enters the route passage detection area 202a. When the in-vehicle device 1 for a bus determines whether or not the bus stop X (not shown) that has stopped before and the bus stop Y corresponding to the approached route passage detection area 202a are continuous on the route, and if it is determined to be continuous. , Output arrival information.

Bus B further travels, enters the stop detection area 201a, and stops. When the bus B departs and exits from the stop detection area 201a, the in-vehicle device 1 for the bus determines whether or not the passed route passage detection area 202a and the stop detection area 201a are associated with a common stop.

Outputs the next stop guidance information that guides the next stop Z (not shown) that stops continuously.

FIG. 1B is a schematic diagram for explaining another example of processing of the in-vehicle device 1 for a bus. When the bus B travels along the route in the direction of the arrow (to the right in the figure), it enters the stop detection area 201c and exits. Even if the bus stop Y is a bus stop that continuously stops on the route to the bus stop X that stopped immediately before, the guidance information is not output at this point.

After that, the bus B travels clockwise in the rotary R and enters the route passage detection area 202c. The in-vehicle device 1 for a bus determines that the bus stop X that has stopped before and the bus stop Y corresponding to the route passage detection area 202c are continuous, and outputs arrival guidance information.

Bus B further travels and passes through the stop detection area 201c again. In the in-vehicle device 1 for a bus, the bus stop X that has stopped before and the bus stop Y that has passed this time are continuous, and the route passage detection area 202c and the stop detection area 201c that have passed are associated with a common stop.

When the current position enters the bus stop detection area and exits, it is assumed that the bus has passed the bus stop in the bus stop detection area. When the current position leaves the stop detection area, the guidance determination unit 113 stores the stop in the stop detection area as a front stop in the front stop storage area of the storage unit 150, which will be described later.

Further, the guidance determination unit 113 determines whether or not the current position of the bus B has entered the route passage detection region. When the guidance determination unit 113 determines that the in-vehicle device 1 for a bus has entered the route passage detection area, the guide determination unit 113 stores the stop in the route passage detection area that has entered as the next stop in the next stop storage area of the storage unit 150. When the next stop is continuous with the previous stop on the route, the guidance determination unit 113 notifies the output unit 130 of the arrival guidance information for guiding the arrival at the next stop.

Further, when the guidance determination unit 113 determines that the current position has left the stop detection area, the guidance determination unit 113 determines whether or not the stop in the exited stop detection area is stored in the storage unit 150 as the next stop. In addition, the guidance determination unit 113 determines whether or not the bus stop in the exited bus stop detection area is continuous with the previous bus stop on the route. When all of these conditions are satisfied, the guidance determination unit 113 determines that it outputs the next stop guidance information for guiding other stops that continuously stop at the next stop on the route, and outputs the next stop guidance information to the output unit 130. Notice.

Further, the guidance determination unit 113 outputs detour information indicating that the bus B has detoured when the bus B travels a predetermined distance before entering the route passage detection area of the stop that is continuous on the route to the previous stop. Then it is determined. The guidance determination unit 113 notifies the output unit 130 of the detour information.

The mileage acquisition unit 114 acquires the mileage of the bus B. The mileage acquisition unit 114 acquires the mileage measured using, for example, the vehicle speed pulse of the bus B via the communication unit 140. The mileage acquisition unit 114 may receive the vehicle speed pulse via the communication unit 140 and calculate the mileage.

The storage unit 150 stores the stop information 151 and the guidance information 152.

The guidance information 152 includes the next stop guidance information 1521, the arrival guidance information 1522, and the detour information 1523.

The next stop guidance information 1521 is information for guiding the next stop. The arrival guidance information 1522 is information that guides the bus to arrive soon, or information that guides the arrival to the next stop soon.

The detour information 1523 is information for informing the customer that the bus B is detouring. The detour means traveling on a route that deviates from the predetermined regular route due to an irregular situation such as an accident or construction, and then returning to the regular route. The next stop guidance information 1521, arrival guidance information 1522, and detour information 1523 are associated with a stop ID that identifies the stop. The arrival guidance information 1522 or the detour information 1523 may have the same contents regardless of the stop ID.

FIG. 3 is a diagram showing an example of the data structure of the bus stop information 151. The stop information 151 includes a stop ID 151a, a stop position 151b, a stop range 151c, a passing route position 151d, a passing route range 151e, a next stop ID 151f, a distance between stops 151g, and an end point flag 151h.

The bus stop position 151b is coordinate information indicating, for example, the latitude and longitude of the bus stop. The bus stop range 151c is information indicating the radius of the bus stop detection area. The stop detection area is defined by a circular area centered on the stop position 151b and having a radius of the stop range 151c.

The passage path position 151d is information for specifying the center point of the path passage detection region. The passage path position 151d is, for example, coordinate information indicating the latitude and longitude of the center point of the path passage detection region. The passage path range 151e is information indicating the radius of the path passage detection region. The path passage detection region is defined by a circular region centered on the pass path position 151d and having a pass path range 151e as a radius.

The method of specifying the bus stop detection area and the route passage detection area is not limited to this. For example, the bus stop detection area and the route passage detection area may be rectangular or elliptical, and the bus stop information 151 may include information that can identify the rectangular or elliptical bus stop detection area and the route passage detection area. Further, the stop range 151c and the passage route range 151e may have constant values regardless of the stop, or may have different values depending on the stop.

The next stop ID 151f is identification information that identifies another stop that continuously stops on the route at the stop specified by the stop ID 151a. It can be said that the bus stop ID 151a and the next bus stop ID 151 are information indicating the arrival order of the bus stops.

The distance between stops 151g is information indicating the distance between the stop specified by the stop ID 151a and another stop specified by the next stop ID 151f. The end point flag 151h is information indicating whether or not the stop of the related stop ID 151a is the end point (for example, 0: not the end point, 1: end point).

When the bus stop is shared by a plurality of different routes, the bus stop information 151 may include information for specifying each route in each record.

FIG. 4 is a diagram showing a hardware configuration example of the in-vehicle device 1 for a bus. The in-vehicle device 1 for a bus includes an arithmetic processing unit 210.

The arithmetic processing unit 210 is a central unit in the vehicle-mounted device 1 for a bus, and includes a CPU (Central Processing Unit) 211, a RAM (Random Access Memory) 212, a non-volatile memory 213, and a network I / F (Interface) 214. .. Each component is connected by a bus.

The CPU 211 executes the process according to the program stored in the RAM 212 or the non-volatile memory 213. The RAM 212 is a storage device, and functions as a storage area for temporarily reading programs and data. The non-volatile memory 213 is a non-volatile memory such as a flash memory, and is used as a storage destination for programs and various data. The network I / F 214 is an interface for connecting the in-vehicle device 1 for a bus to a network or an external device (not shown).

In the in-vehicle device 1 for a bus, processing is performed by the CPU 211 that operates according to the program read on the RAM 212 or the non-volatile memory 213.

The processing of each component of the in-vehicle device 1 for a bus may be executed by one hardware or may be executed by a plurality of hardware. Further, the processing of each component of the vehicle-mounted device 1 for a bus may be realized by one program or may be realized by a plurality of programs.

FIG. 5 is a flowchart showing an example of guidance processing of the in-vehicle device 1 for a bus. This process is started when, for example, the input unit 120 receives an input operation indicating the start of the guidance process. When a bus stop is shared by a plurality of different routes, the in-vehicle device 1 for a bus accepts input of information for specifying a route to be traveled, and uses a record of stop information 151 related to the input route for guidance processing. During this process, the current position acquisition unit 112 acquires the current position of the bus B, for example, periodically.

First, the guidance determination unit 113 determines whether or not the current position has left the bus stop detection area (step S11). Specifically, the guidance determination unit 113 determines whether or not the current position of the bus B acquired by the current position acquisition unit 112 has entered the bus stop detection area and has exited the bus stop detection area. To judge. When the guidance determination unit 113 determines that the current position has entered the stop detection area and has exited, the process proceeds to step S12.

The stop in the stop detection area where the current position is determined to have left in this step is, for example, the stop at the start of travel of the bus B (the first stop). When the guidance determination unit 113 determines that the current position has not entered the bus stop detection area or the current position has not exited the bus stop detection area, the process of step S11 is repeated.

Next, the guidance determination unit 113 stores the previous stop (step S12). Specifically, the guidance determination unit 113 refers to the bus stop information 151 and identifies the bus stop ID 151a related to the bus stop detection area determined to have exited in step S11. The guidance determination unit 113 stores the specified stop ID as a front stop in a front stop storage area (not shown) of the storage unit 150.

Next, the guidance determination unit 113 identifies the next stop candidate (step S13). The guidance determination unit 113 refers to the bus stop information 151, and identifies the next bus stop ID 151f associated with the bus stop ID of the previous bus stop stored in the storage unit 150 in step S12. The guidance determination unit 113 stores the specified stop ID as a next stop candidate in the next stop candidate storage area (not shown) of the storage unit 150.

Next, the guidance determination unit 113 outputs the next stop guidance information (step S14). The guidance determination unit 113 refers to the guidance information 152, identifies the next stop guidance information 1521 that guides the next stop candidate stored in step S13, and notifies the output unit 130. The output unit 130 causes the output device 312 to output the next stop guidance information 1521.

Next, the guidance determination unit 113 determines whether or not the current position has entered the route passage detection area of the next stop candidate (step S15). Specifically, the guidance determination unit 113 refers to the bus stop information 151 and identifies a route passage detection area associated with the bus stop ID of the next bus stop candidate stored in step S13. The guidance determination unit 113 determines whether or not the current position has entered the specified route passage detection area.

When the guidance determination unit 113 determines that the current position has entered the route passage detection area of the next stop candidate (when “YES” in step S15), the output unit 130 stores the next stop and the arrival guidance information 1522. Is output (step S16). Specifically, the guidance determination unit 113 stores the stop ID of the next stop candidate stored in step S13 as the stop ID of the next stop in the next stop storage area. In this case, the previous stop and the next stop are continuous on the route.

In addition, the guidance determination unit 113 refers to the guidance information 152 and uses the stop ID of the next stop to specify the arrival guidance information 1522 indicating that the bus will arrive at the stop. The guidance determination unit 113 notifies the output unit 130 of the specified arrival guidance information 1522. The output unit 130 outputs the arrival guidance information 1522 to the output device 312.

Next, the guidance determination unit 113 determines whether or not the next stop is the end point (step S17). The guidance determination unit 113 refers to the bus stop information 151, and determines whether or not the end point flag 151h associated with the stop ID of the next stop stored in step S16 is information indicating that the end point is the end point. When the guidance determination unit 113 determines that the next stop is the end point (when “YES” in step S17), the control unit 110 ends the process of this flowchart.

When the guidance determination unit 113 determines that the next stop is not the end point (when "NO" in step S17), the guidance determination unit 113 determines whether or not the current position has left the stop detection area (step). S18). Specifically, when the guidance determination unit 113 determines that the current position acquired by the current position acquisition unit 112 has entered or exited any of the bus stop detection areas, the process proceeds to step S19. When the guidance determination unit 113 determines that the current position has not entered the bus stop detection area or has not exited the bus stop detection area, the process of step S18 is repeated.

Next, the guidance determination unit 113 determines whether or not the stop in the exited stop detection area is the next stop (step S19). Specifically, the guidance determination unit 113 identifies the stop ID of the stop detection area determined to have exited in step S18. The guidance determination unit 113 proceeds to step S20 when the specified stop ID is the stop ID of the next stop stored in the next stop storage area.

In addition, the fact that the stop ID of the exited stop detection area is the stop ID of the next stop means that the stop is continuous with the stop of the stop detection area that exited immediately before the current position entered the route passage detection area. It means that the bus has passed the stop corresponding to the route passage detection area that has entered.

When the guidance determination unit 113 determines that the stop in the exited stop detection area is not the next stop (when "NO" in step S19), the guidance determination unit 113 returns the process to step S18.

When the guidance determination unit 113 determines that the stop in the exited stop detection area is the next stop (when "YES" in step S19), the guidance determination unit 113 updates the previous stop and the next stop candidate. (Step S20).

Specifically, the guidance determination unit 113 deletes the stop ID of the previous stop stored in the front stop storage area in step S12. The guidance determination unit 113 stores the stop ID stored in the next stop storage area in step S16 as the stop ID of the previous stop in the previous stop storage area.

Further, the guidance determination unit 113 refers to the stop information 151 and identifies the next stop ID 151f associated with the stop ID of the previous stop. The guidance determination unit 113 deletes the stop ID of the next stop candidate stored in step S14, and stores the specified stop ID as the next stop candidate in the next stop candidate storage area.

Next, the guidance determination unit 113 outputs the next stop guidance information (step S21). The guidance determination unit 113 refers to the guidance information 152 and guides the next stop candidate stored in step S20 to the next stop guidance information 1521. Is specified and notified to the output unit 130. The output unit 130 causes the output device 312 to output the next stop guidance information 1521.

After that, the control unit 110 returns the process to step S15. As a result, the guidance process is repeated until the next stop reaches the end point (“YES” in step S17).

When the guidance determination unit 113 determines that the current position has not entered the route passage detection area of the next stop candidate (when “NO” in step S15), whether or not the guidance determination unit 113 has traveled a predetermined distance. (Step S22). When the guidance determination unit 113 determines that the current position has not entered the route passage determination area of the next stop candidate, the vehicle passes through the stop detection area and then continuously stops at the stop in the stop detection area. It means that the route passage detection area of the bus stop has not been reached.

The guidance determination unit 113 refers to the bus stop information 151, and identifies the inter-stop distance 151 g related to the stop ID of the previous stop stored in the storage unit 150 in step S12 or step S20.

The guidance determination unit 113 specifies a predetermined distance for determining the execution of the output of the detour information 1523 by using the distance between the stops. For example, the guidance determination unit 113 specifies a value obtained by adding a predetermined value to the distance between stops as a predetermined distance. Using the mileage acquired by the mileage acquisition unit 114, the guidance determination unit 113 acquires the distance traveled by the bus B after the current position exits the stop detection area in step S11 or step S18. The guidance determination unit 113 determines whether or not the traveling distance is equal to or greater than a predetermined distance.

When the guidance determination unit 113 determines that the vehicle has not traveled a predetermined distance (“NO” in step S22), the guidance determination unit 113 returns the process to step S15.

When the guidance determination unit 113 determines that the vehicle has traveled a predetermined distance (when “YES” in step S22), the guidance determination unit 113 determines whether or not the detour information 1523 has been output (step S23). .. It is assumed that the guidance determination unit 113 refers to the storage unit 150 by using the stop ID of the next stop candidate specified in step S13 or step S20, and has already output the detour information 1523 indicating that the route to the stop has been detoured. Determine the presence or absence of information.

When the guidance determination unit 113 determines that the detour information 1523 has been output (when “YES” in step S23), the guidance determination unit 113 returns the process to step S15.

When the guidance determination unit 113 determines that the detour information 1523 has not been output (when “NO” in step S23), the output unit 130 outputs the detour information 1523 (step S24). Specifically, the guidance determination unit 113 uses the stop ID of the next stop candidate specified in step S13 to identify the detour information 1523 indicating that the route to the stop has been detoured, and notifies the output unit 130. .. The output unit 130 causes the output device to output the detour information 1523.

Further, the guidance determination unit 113 stores in the storage unit 150 information indicating that the detour information 1523 indicating that the route to the stop has been detoured has been output. After that, the control unit 110 returns the process to step S15. The information indicating that the detour information 1523 has been output is the information indicating that the guidance determination unit 113 determines that the current position is within the route passage detection area of the next stop candidate (when “YES” in step S15). It is erased by 113.

In the present embodiment, when the output unit 130 receives a notification of new guidance information from the guidance determination unit 113 during the output of the guidance information, the output unit 130 stops the output of the guidance information and outputs the notified new guidance information. To do.

FIG. 6 is a diagram showing an example of an outline of guidance processing of an in-vehicle device for a bus when detouring is performed. It is assumed that the bus B is at the position shown in FIG. 6 after passing the stop S (not shown). Bus B normally travels straight on the regular route q from the left to the right as shown in FIG. In this case, the bus B passes through the route passage detection area 202d and the stop detection area 201d in this order. However, if there is a point k under construction on the route, the bus B travels on a detour route p that avoids the point k. In this case, the bus B passes through the stop detection area 201d before passing through the route passage detection area 202d.

The bus stop S and the bus stop T are predetermined as the bus stops that stop continuously in the bus stop information 151. Even when the bus B passes through the stop detection area 201d of the stop T continuous with the stop S, it does not pass through the route passage detection area 202d of the stop T, so that the guidance determination unit 113 uses the guidance information 152 of the stop T. Is not output.

The guidance determination unit 113 calculates a predetermined distance for outputting the detour information 1523 by using the distance between the stops S and the stop T. As described above, when the bus B has traveled a predetermined distance, the bus B has not yet entered the route passage detection area 202d, and the detour information 1523 has not been output for the stop T, the guidance determination unit 113 , Outputs detour information 1523 indicating that the route to the stop T is being detoured.

FIG. 7 is a diagram showing an example of a detour information display screen. Information indicating that the bus B is detouring is displayed on the detour information display screen. As shown in FIG. 7, the name of the next stop may be displayed on the detour information display screen.

As described above, the guidance determination unit 113 identifies the detour information 1523 by using the stop ID of the next stop candidate. The detour information 1523 includes, for example, the name of the next stop candidate. When the guidance determination unit 113 notifies the output unit 130 of the detour information 1523, the output unit 130 displays the detour information display screen via the output device 312.

The detour information 1523 may be audio instead of video. In that case, the output unit 130 broadcasts the detour information 1523 including the voice information indicating that the bus B is detouring into the bus B via the output device 312. The detour information 1523 may include voice information indicating the name of the next stop candidate.

The explanation is returned to FIG. After the detour information 1523 is output, when the bus B enters the route passage detection area 202d, the arrival guidance information 1522 indicating that the bus B will soon arrive at the stop T is output. When the bus B further travels and exits the stop detection area 201d, the next stop guidance information 1521 that guides the stop U (not shown) that continuously stops at the stop T is output.

According to this embodiment, even when the traveling route is complicated, it is possible to output the guidance information 152 that guides the bus stop to be stopped more accurately and at an appropriate timing. Further, by outputting the detour information 1523 when the bus B detours, it is possible to eliminate the customer's anxiety that the bus B may not be traveling on an appropriate route.

Although the embodiments and modifications according to the present invention have been described above, the present invention is not limited to the above-described embodiments, and includes various modifications. For example, an example of the above-described embodiment has been described in detail for the sake of clarity of the present invention, and the present invention is not limited to those having all the configurations described here. Further, it is possible to replace a part of the configuration of one example of a certain embodiment with the configuration of another example. It is also possible to add the configuration of another example to the configuration of one example of one embodiment. Further, it is possible to add / delete / replace a part of the configuration of one example of each embodiment with another configuration. Further, each of the above configurations, functions, processing units, processing means and the like may be realized by hardware by designing a part or all of them by, for example, an integrated circuit. In addition, the control lines and information lines in the figure indicate what is considered necessary for explanation, and do not necessarily indicate all. You can think of almost all configurations as interconnected.

For example, in the above-described embodiment, the route passage detection area is used to determine whether or not the route to the bus stop is being passed, and the arrival guidance information 1522 is output. However, the area for determining that the bus has passed the route to the bus stop and the area for determining the execution of the output of the arrival guidance information 1522 may be different.

In this case, the bus stop information 151 includes a first route passage detection area for detecting the passage to the bus stop and a second route passage detection area for outputting the arrival guidance information 1522. The first path passage detection area and the second path passage detection area may be set individually regardless of each other, or may be set so that the center points are common and the radii are different.

In addition, there may be a plurality of route passage detection areas for determining whether or not the route to the bus stop is being passed. In that case, in step S15 shown in FIG. 5, when determining whether or not the current position of the bus B has entered the route passage detection area of the next stop candidate, the guidance determination unit 113 uses all the routes corresponding to the next stop candidate. When passing through the passage detection area, it is determined that the current position is within the route passage detection area of the next stop candidate.
