When such a process is started, the staircase determination unit 124 determines whether or not the down staircase is within a predetermined range (for example, within 500 m) (step S001). Specifically, the stairs determination unit 124 determines whether or not the down stairs are within a predetermined range by using the position information indicating the current location acquired from the current location calculation unit 123 and the map information 210 as described above. .. Then, when it is determined that there is no down staircase within the predetermined range (No in step S001), the staircase determination unit 124 performs the process of step S001 again. On the other hand, when it is determined that there is a down staircase within the predetermined range (Yes in step S001), the staircase determination unit 124 shifts the process to step S002.

In step S002, the moving means specifying unit 126 specifies the moving means of the user who owns the navigation application display terminal 100. Specifically, the moving means specifying unit 126 identifies the moving means (any one of automobile, motorcycle, bicycle, and walking) based on the average moving speed or the maximum moving speed of the moving means calculated by the moving speed calculation unit 125. do.

Next, the moving means specifying unit 126 determines whether or not the moving means of the user specified in step S002 is an automobile or a motorcycle (step S003). Then, when it is determined that the user's moving means is an automobile or a motorcycle, the moving means specifying unit 126 shifts the process to step S004. On the other hand, when it is determined that the specified moving means is not an automobile or a motorcycle, the moving means specifying unit 126 shifts the process to step S007.

In step S004, the warning unit 127 determines whether or not the distance to the down stairs is within a predetermined range (for example, within 300 m). Then, when it is determined that the distance is not within the predetermined range (No in step S004), the warning unit 127 returns the process to step S001. On the other hand, when it is determined that the distance is within a predetermined range (Yes in step S004), the warning unit 127 shifts the process to step S005.

Next, the warning unit 127 outputs a warning information generation instruction (step S005). Specifically, the warning unit 127 sends an instruction to generate warning display information (for example, display information for pop-up display of a warning message such as "There is a staircase ahead, please be careful") to the output processing unit 122. Output. Further, the warning unit 127 outputs a generation instruction of warning voice information (for example, voice information for calling attention such as "There is a staircase ahead, please be careful") to the output processing unit 122. The warning unit 127 may transmit at least one of the warning display information and the warning voice information to the output processing unit 122.

Next, the output processing unit 122 generates predetermined warning information according to the instruction from the warning unit 127. Further, when the navigation application display terminal 100 and the vehicle-mounted device 300 are communicably connected, the output processing unit 122 transmits warning information to the vehicle-mounted device 300 via the communication unit 103, and such a communication connection is established. If not, the output processing unit 122 outputs the warning information to the output device 402 (display and speaker) of the navigation application display terminal 100 (step S006). Further, when the output processing unit 122 transmits or outputs the warning information, the output processing unit 122 returns the processing to step S001.

The vehicle-mounted device 300 that has acquired the warning information pops up the acquired warning display information on the display. Specifically, the on-board unit 300 pops up a warning message indicated by warning display information on a map displaying a car mark indicating a current location. Further, the vehicle-mounted device 300 outputs the acquired warning voice information to the vehicle-mounted speaker 310. As a result, predetermined warning display information is displayed on the display of the vehicle-mounted device 300 when the down stairs are approaching, and a voice message calling attention is output from the vehicle-mounted speaker 310.

FIG. 5 is a diagram showing a screen example 500 of the vehicle-mounted device 300 on which the warning display information is displayed. As shown in the figure, the display of the vehicle-mounted device 300 displays a map 501 around the current location, a car mark 502 indicating the current location, and predetermined warning display information 503 indicating that the down stairs are approaching.

When the navigation application display terminal 100 outputs warning information, the display of the navigation application display terminal 100 has a map around the current location, a car mark indicating the current location, and a predetermined warning notifying that the down stairs are approaching. Display information is popped up, and a voice message calling attention is output from the speaker. The screen example of the navigation application display terminal 100 on which the warning display information is displayed is the same as the screen example of the vehicle-mounted device 300 shown in FIG.

It will be described back to FIG. In step S003 described above, when it is determined that the user's means of transportation is not a car or a motorcycle (No in step S003), the means of transportation specifying unit 126 determines whether or not the means of transportation of the user is a bicycle (step). S007). Specifically, the moving means specifying unit 126 determines whether or not the moving means of the user specified in step S002 is a bicycle. Then, when it is determined that the bicycle is not a bicycle (No in step S007), the moving means specifying unit 126 returns the process to step S001. On the other hand, when it is determined that the moving means is a bicycle (Yes in step S007), the moving means specifying unit 126 shifts the process to step S008.

In step S008, the warning unit 127 determines whether or not the distance to the down stairs is within a predetermined range (for example, within 100 m). Then, when it is determined that the distance is not within the predetermined range (No in step S008), the warning unit 127 returns the process to step S001. On the other hand, when it is determined that the distance is within a predetermined range (Yes in step S008), the warning unit 127 shifts the process to step S009.

Next, the warning unit 127 outputs a warning information generation instruction (step S009). Specifically, the warning unit 127 pops up and displays a predetermined warning display information (for example, "There is a staircase ahead, please be careful", as in step S005 described above. ) Is output to the output processing unit 122. Further, the warning unit 127 outputs a generation instruction of predetermined warning voice information (for example, voice information for calling attention such as "There is a staircase ahead, please be careful") to the output processing unit 122. The warning unit 127 may transmit at least one of the warning display information and the warning voice information to the output processing unit 122.

Next, the output processing unit 122 generates predetermined warning information according to the instruction from the warning unit 127, and outputs the predetermined warning information to the display and the speaker of the navigation application display terminal 100 (step S010). As a result, a map around the current location, a car mark indicating the current location, and predetermined warning display information notifying that the down stairs are approaching are popped up on the display of the navigation application display terminal 100, and the speaker alerts the user. A voice message prompting is output. The screen example of the navigation application display terminal 100 on which the warning display information is displayed is the same as the screen example of the vehicle-mounted device 300 shown in FIG.

When the output processing unit 122 outputs the warning information, the output processing unit 122 returns the processing to step S001.

The staircase warning process has been described above. According to the navigation application display terminal 100 that performs such processing, it is possible to output a warning regarding the existence of stairs at a timing according to the means of transportation. As a result, the user can recognize in advance that there are stairs on the course.

Further, according to the navigation application display terminal 100 according to the present embodiment, it is possible to determine whether the means of transportation is a car (and a motorcycle) or a bicycle, and the warning timing is changed according to the means of transportation. Can be done. This makes it possible to avoid inconveniences that occur in the case of automobiles and motorcycles.

FIG. 6 is a diagram showing an example of an area including stairs. As shown, the stairs 601 are often connected to a relatively narrow road 602 in the city. Further, the narrow road 602 is often one-way, and the area shown in the figure assumes that there is a staircase 601 between the user's current location 603 and the location 604 the user intends to go to.

For example, if a warning about stairs is output near stairs 601 or around position A beyond a one-way road, it becomes difficult for the user driving the car to return to the road in the desired direction. On the other hand, in the case of a bicycle, you can easily return to the road in the direction you want to go, regardless of whether it is a one-way street or not. Therefore, the navigation application display terminal 100 makes it possible to determine whether the means of transportation is a car (or motorcycle) or a bicycle, and in the case of a car or the like, the stairs approach at an earlier timing than the bicycle, that is, at a position farther from the stairs. It is possible to output a warning to inform the user that this is the case.

The present invention is not limited to the above-described embodiment, and various modifications are possible. For example, the output processing unit 122 provides information indicating the position of the down stairs (for example, a circle surrounding the down stairs, display information for displaying the down stairs in a color or pattern different from that of other roads, etc.). It may be generated as warning display information together with the arousal text.

FIG. 7A is a diagram showing a screen example 700 in which the circle 701 indicating the position of the down stairs and the caution statement 702 are displayed. FIG. 7B is a diagram showing a screen example 710 in which a pattern 711 indicating the position of the down stairs and a caution statement 712 are displayed. The circle 701 in FIG. 7A indicates the position of the down stairs. The shaded pattern 711 in FIG. 7B shows the position of the down stairs. Further, on the maps of FIGS. 7A and 7B, a warning sentence 712 notifying the user that the down stairs are approaching is displayed in a pop-up. As a result, the user can know that the down stairs are approaching and can recognize the position of the down stairs.

Further, in the above-described embodiment, predetermined warning display information and warning voice information are output when the means of transportation is determined to be an automobile, motorcycle, or bicycle, but warning display information or the like is also output when the means of transportation is walking. You may try to do it.

Specifically, when it is determined that the means of transportation is walking, the warning unit 127 outputs a warning information generation instruction to the output processing unit 122 when the distance to the down stairs is within a predetermined range (for example, within 10 m). do. Further, the output processing unit 122 outputs the generated warning display information and warning voice information to the display and speaker of the navigation application display terminal 100. As a result, the pedestrian can recognize in advance that the stairs are approaching.

Further, the navigation application display terminal 100 may output warning information notifying that the upstairs are approaching. Whether or not the stairs are uphill may be determined by using the altitude information 221 included in the link information 213 as described above. Since the ascending stairs cannot be passed by automobiles, motorcycles and bicycles, the user can search for detours in advance by outputting warning information.

Further, the output processing unit 122 may calculate the distance to the stairs using the map information 210 and generate warning display information including a warning statement and the distance to the stairs. This allows the user to know the distance to the stairs.

The present invention is not limited to the above-described embodiments and modifications, and includes various embodiments and modifications in addition to these. For example, the above-described embodiment has been described in detail in order to explain the present invention in an easy-to-understand manner, and is not necessarily limited to the one including all the described configurations. Further, it is possible to replace a part of the configuration of a certain embodiment with the configuration of another embodiment or a modification, and it is also possible to add the configuration of another embodiment to the configuration of a certain embodiment. Further, it is possible to add / delete / replace other configurations with respect to a part of the configurations of each embodiment.
