<System configuration>
FIG. 1 is a diagram illustrating a configuration example of a system according to the present embodiment. The system according to the present embodiment includes a control information providing device 10, a control device 20, and an output device 30. The control information providing device 10, the control device 20, and the output device 30 are connected so as to be able to communicate with each other via a wireless or wired communication network N.

  The control information providing device 10 and the control device 20 are devices such as servers, for example, and include a processor, a memory, and a storage device. The output device 30 is a device used by a user (driver) and can notify the driver of various types of information. The output device 30 may be a portable terminal that can be carried while the user is driving, such as a smartphone or a tablet terminal, or a car navigation device that can be mounted on a car or a motorcycle. Also good.

  For example, the enforcement information providing device 10 conducts the enforcement of speed control in the city of xx on x month x, for example, the enforcement target area and enforcement type (for example, enforcement of speed violation, seat belt enforcement, etc.) And information on the date and time of enforcement (hereinafter referred to as “regulation schedule information”). The control information providing apparatus 10 may be a Web server that publishes homepages such as the Tokyo Metropolitan Police Department or prefectural police, or a format that is easy to be used by a third party by collecting public control information published on these Web servers. It may be a server that publishes the information converted into.

  The control device 20 collects control schedule information from the control information providing device 10 and is included in a control target area included in a predetermined range from the current position of the output device 30 or on a road from a departure place to a destination. In the control area, the device has a function of extracting one or more points (hereinafter referred to as “notification points”) that are points included in the map data and that should output a message prompting safe driving. Specifically, the notification point is a traffic signal installation point, a temporary stop point, a right turn prohibition point, or the like included in the map data. Further, the control device 20 notifies the output device 30 of the extracted notification point.

  The output device 30 moves with the movement of the user, and the distance between the current position detected using GPS or the like and one of the one or more notification points notified from the output device 30 Is a device that has a function of outputting a message prompting the user to drive safely when the vehicle approaches a predetermined distance (for example, 30 meters before the notification point).

  The control device 20 and the output device 30 may be configured as an information output system including one information processing device, or may be configured as an information output system including one or more independent information processing devices. .

  Further, the control device 20 and the output device 30 may be integrated to operate as a navigation device. In this case, detection of the current position and display of the navigation screen may be performed on the output device 30 side, and processing such as route search may be performed on the control device 20 side. Further, the present invention is not limited to this, and all processes such as detection of the current position, display of the navigation screen, and route search may be performed on the output device 30 side.

<Functional block configuration>
FIG. 2 is a diagram illustrating an example of a functional block configuration of the control device 20. The control device 20 according to the present embodiment includes a communication unit 21, an acquisition unit 22, an extraction unit 23, and a search unit 24. The communication unit 21, the acquisition unit 22, the extraction unit 23, and the search unit 24 are realized by a processor executing a program stored in a memory in the control device 20.

  The communication unit 21 has a function of communicating with the enforcement information providing apparatus 10 and the output apparatus 30 via the communication network N.

  The acquisition unit 22 has a function of acquiring control schedule information from the control information providing apparatus 10. The acquisition unit 22 may acquire the control schedule information at a predetermined cycle (for example, once a week, once a month, etc.), or provide the control information with a notification that the control schedule information has been updated. The control schedule information may be acquired at the timing received from the apparatus 10. FIG. 3 shows an example of control schedule information. “Regulation date and time” indicates the date and time when the traffic control activity is performed, “Regulation target area” indicates the area where the traffic control activity is performed, and “Regulation type” indicates the traffic control activity performed at the control location. Indicates the type. In the “control target area”, a specific municipality name, an area code specifying the municipality, or the like may be stored, or polygon information specifying the control target area on the map may be stored. In addition, in the “control target area”, a name of a road on which control is performed, a code for specifying a road, or the like may be stored.

  The extraction unit 23 promotes safe driving in a control target area included within a predetermined range from the current position of the output device 30 or a control target area included on a route (on the road) from the departure point to the destination. It has a function of extracting one or more notification points indicating points where messages should be output from map data. Further, the extraction unit 23 transmits the extracted data indicating “one or more notification points” to the output device 30 via the communication unit 21. In addition, when the route guidance is not performed by the navigation function, the extraction unit 23 extracts one or more notification points in the control target area included within a predetermined range from the current position of the output device 30 and uses the navigation function to extract the route. When performing the guidance, one or more notification points may be extracted in a control target area included on the route (on the road) from the departure point to the destination.

  In addition, the extraction unit 23 searches for candidate notification points from the map data, and among the searched notification point candidates, the notification corresponding to the “notification point type” associated with the enforcement type performed in the enforcement target area. Point candidates are extracted as one or more notification points. “Notification point type” means what kind of point the notification point is, for example, a point where a traffic light is installed. The extraction unit 23 accesses the setting information (hereinafter referred to as “extraction setting information”) in which the types of notification points to be extracted for each type of control are associated with each other. Recognize the type.

  FIG. 4 shows an example of the extraction setting information. The extraction setting information assumes information created in advance by an administrator, for example, and can be arbitrarily changed. The extraction setting information may be stored in a memory in the control device 20, or may be stored in a storage device connected to the control device 20 through a communication network. “Speed limit change point” means a point where the speed limit changes (for example, a point where the maximum speed changes from 60 km / h to 40 km / h). The “entrance point of the zone 30” means a point that is the entrance of the area set in the zone 30. “Signal installation point” means a point where a signal is installed. “Temporary stop point” means a point where a stop sign is installed. “Advancing direction traffic classification installation point” means a point where a traveling direction traffic classification sign is installed. “Course change prohibition point” means a point where a route change prohibition sign is installed. “Level crossing point” means a point where a level crossing exists. The “parking prohibition point” means a point set to prohibit parking. “Weight limit sign installation point” means a point where a weight limit sign is installed.

  For example, in the example of FIG. 4, “traffic light installation point”, “temporary stop point”, “travel direction traffic classification setting point”, and “route change prohibited point” are set for “intersection violation control”. . This is because map traffic data points where traffic lights are installed, points where stop signs are installed, points where traveling direction traffic signs are installed, and course changes are prohibited for intersection violation enforcement This indicates that the point where the sign is installed should be extracted as the “notification point”.

  In the example of FIG. 4, the control type for which “-” is set means that the control type is not a type that can identify the notification point in the map data. The extraction unit 23 refers to the extraction setting information to determine whether or not the control type is a type that can specify the notification point in the map data. If the above notification points are extracted and it is determined that the type is not identifiable, one or more notification points may not be extracted. For example, “-” is set for “seat belt control”. This is because the seat belt control is performed at an arbitrary location in the entire control target area, and is not considered to be performed at a specific point. However, the enforcement type for which "-" is set is an example for explaining FIG. 4, and the type of any notification point can be set in the same manner as other enforcement types.

  The search unit 24 has a function of performing route search in the navigation function. More specifically, the search unit 24 searches for a route from the departure place to the destination specified by the user via the output device 30 and transmits the searched route to the output device 30. In addition, you may make it implement | achieve the navigation function in this embodiment using a prior art.

  FIG. 5 is a diagram illustrating an example of a functional block configuration of the output device 30. The output device 30 according to the present embodiment includes a communication unit 31, a position detection unit 32, and an output unit 33. The communication unit 31, the position detection unit 32, and the output unit 33 are realized by a processor executing a program stored in a memory in the output device 30.

  The communication unit 31 has a function of communicating with the control device 20 via the communication network N.

  The position detection unit 32 has a function of detecting the current position using a GPS device, a vehicle speed sensor, or the like included in the output device 30. The position detector 32 may further detect the traveling direction.

  The output unit 33 has a function of displaying the current position detected by the map and position detection unit 32 on a display or the like included in the output device 30. Also. The output unit 33 has a function of displaying the route searched by the search unit 24 of the control device 20 on a map. Further, the output unit 33 is configured such that the distance between the current position detected by the position detection unit 32 and any one of the “one or more notification points” notified from the control device 20 is a predetermined distance. When approaching, it has a function of outputting a message for promoting safe driving.

  As described above, the control device 20 and the output device 30 may be configured as an information output system including one information processing device. In this case, the communication unit 21, the acquisition unit 22, the extraction unit 23 and the search unit 24 included in the control device 20, the communication unit 31 included in the output device 30, the position detection unit 32, and the output unit 33 are included in one information processing device. This is possible.

  Further, the search unit 24 provided in the control device 20 may be provided in the output device 30. That is, the route search function in the navigation function may be mounted on the output device 30 side.

  Further, the extraction unit 23 included in the control device 20 and the output unit 33 included in the output device 30 may be collectively defined as a “control unit”. That is, the control unit is a functional block that performs both the processing performed by the extraction unit 23 and the processing performed by the output unit 33 described in the present embodiment.

<Processing procedure>
Next, the processing procedure performed by the information output system according to the present embodiment will be described separately for the case where route guidance is not performed by the navigation function and the case where route guidance is performed.

(When route guidance is not provided)
FIG. 6 is a flowchart illustrating an example of a processing procedure (without route guidance) performed by the control device 20. The flowchart illustrated in FIG. 6 is executed, for example, in a state where the navigation function is activated and only the map display is performed without performing route guidance in the output device 30. Further, the flowchart shown in FIG. 6 is repeatedly performed until the function described in the present embodiment (the function of outputting a message prompting the safe driving to the user based on the control schedule information) is completed.

  First, the extracting unit 23 searches the data corresponding to the current date and time from the control schedule information, thereby acquiring the enforcement target area and the enforcement type at the current date and time (S101). Subsequently, the extraction unit 23 acquires the current position detected by the position detection unit 32 of the output device 30 from the output device 30 (S102). Subsequently, the extraction unit 23 searches for candidates for notification points existing within a predetermined range from the current position of the output device 30 on the map (S103).

  Specifically, the notification point candidates are notification points corresponding to all types of notification points set in the “notification point type” of the extraction setting information. That is, the extraction unit 23 has all speed limit change points, all zone 30 entrance points, all traffic signal installation points, all existing within a predetermined range from the current position of the output device 30 as notification point candidates. The map is searched for temporary stop points, all travel direction traffic section installation points, all route change prohibition points, all railroad crossing points, all parking prohibition points, and all weight restriction sign installation points. Note that within a predetermined range from the current position of the output device 30 is, for example, a radius N meters (N is a positive number, for example, 500 m, 1000 m, 2000 m, etc.) centered on the current position of the output device 30. In addition, an angle within a predetermined range toward the traveling direction of the output device 30 in a range of radius N meters centered on the current position of the output device 30 (for example, −45 degrees to 0 degrees when the traveling direction is 0 degree) It may be a fan-shaped range divided by a range of 45 degrees or a range of −90 degrees to 90 degrees.

  Subsequently, the extraction unit 23 includes notification points corresponding to the type of notification point that is included in the enforcement target area and is associated with the enforcement type implemented in the enforcement target area, among the notification point candidates. Candidates are extracted as one or more notification points. Further, the extraction unit 23 transmits data indicating one or more extracted notification points (hereinafter referred to as “notification point data”) to the output device 30 (S104).

  For example, it is assumed that the predetermined range in step S103 is a radius of 1000 meters centered on the current position of the output device 30 and that the type of control performed in the control target area is “speed violation control”. In this case, the extraction unit 23 includes a “speed limit changing point” and a “zone 30 entrance point” that exist in both the range of a radius of 1000 meters centered on the current position of the output device 30 and the range subject to the control. Are extracted as notification points.

  The notification point data transmitted by the extraction unit 23 to the output device 30 includes, for example, the notification point position coordinates (for example, latitude and longitude) and the control type (for example, the notification point corresponding to the suspension violation control for each notification point). Or the notification point corresponding to the intersection control), the road link ID of the road where the notification point exists, and the type of road where the notification point exists (either general road or highway) May be. A road link means a road section that connects nodes (intersections, dead ends of roads, etc.) when expressing a road network, and a road link ID uniquely identifies a road section that connects nodes. It means ID to do. When the notification point exists only in one of the traveling directions on the road (for example, a point where a stop sign exists only in the up lane), the notification point data further includes A flag indicating the traveling direction of the road on which the notification point exists may be included.

  When there are a plurality of enforcement target areas and enforcement types acquired in step S101, the extraction unit 23 performs the processing procedure of steps S103 and S104 for each.

  In addition, in the extraction setting information, when “-” is set in the “notification point type” corresponding to the type of enforcement performed in the area subject to enforcement, that is, the type of enforcement performed in the area subject to enforcement is included in the map data. If the notification point is not a type that can identify the notification point, the extraction unit 23 omits the processing procedure of Step S104 for the control type (not extracting the notification point).

  Subsequently, the extraction unit 23 terminates the process when the function described in the present embodiment is terminated, and returns to step S101 and continues the process when not terminated (S105).

  About the flowchart demonstrated above, the extraction part 23 may acquire the enforcement object area and enforcement type in the day by searching the data applicable to the present date from enforcement schedule information in step S101. If the function described in the present embodiment is not terminated (S105-NO), the process may return to step S101 only when the date is straddled, and may be returned to step S102 when the date is not straddled. Since the control schedule information is not frequently updated information, the frequency at which the extraction unit 23 accesses the control schedule information can be set once a day, and the processing load of the control device 20 can be reduced.

  Further, the extraction unit 23 may move to step S103 after grasping that the output device 30 has moved a predetermined distance in step S102.

  In the flowchart described above, the extraction unit 23 does not search for notification point candidates for the entire area to be controlled in step S103, but instead of a notification point that exists within a predetermined range from the current position of the output device 30 on the map. Search only candidates. As a result, it is possible to avoid searching for candidates for notification points for a range that is far from the current position and for which it is not possible to actually move to that place, and that reduces the processing load on the control device 20. It becomes possible.

  FIG. 7 is a flowchart illustrating an example of a processing procedure (without route guidance) performed by the output device 30. The flowchart illustrated in FIG. 7 is executed, for example, in a state where the navigation function is activated and only the map display is performed without performing route guidance in the output device 30. Further, the flowchart shown in FIG. 7 is repeatedly performed until the function described in the present embodiment (the function of outputting a message for prompting safe driving to the user based on the control schedule information) is completed.

  First, the position detection unit 32 detects the current position of the output device 30 using GPS or the like (S201). Subsequently, the output unit 33 has a distance from the current position of the output device 30 within a predetermined distance among one or more notification points included in the notification point data received from the control device 20 (for example, 30 m, 50 m, 100 m). , 150 m, etc.) is determined (S202). If there is a notification point whose distance from the detected current position is within a predetermined distance, the process proceeds to step S203, and if not, the process proceeds to step S201. Subsequently, the output unit 33 outputs a message for promoting safe driving (S203). Specifically, the output unit 33 may output a message such as “Please keep in mind safe driving” from a screen provided in the output device 30, or from a speaker provided in the output device 30, for example, “Safety”. A voice or an alarm sound such as “Please keep in mind driving” may be output.

  Subsequently, the output unit 33 terminates the process when the function described in the present embodiment is terminated, and returns to step S201 and continues the process when not terminated (S204).

  Note that the predetermined distance in step S202 is the type of road on which the output device 30 is traveling (either a general road or an expressway), the maximum speed of the road on which the output device 30 is traveling, or the output device 30 You may make it switch to a different distance according to traveling speed. For example, when the output device 30 is traveling on a highway, the predetermined distance may be 150 m, and when the output device 30 is traveling on a general road, the predetermined distance may be 50 m. As a result, the output device 30 can output a message prompting safe driving to the user at an appropriate timing.

  In addition, in the notification point data acquired from the control device 20, the output unit 33, when there are a plurality of notification points within a specific distance (for example, within 50 m), in step S203, the plurality of notification points. Instead of outputting a message for prompting safe driving every time, a message for prompting safe driving may be collectively output to the plurality of notification points. As a result, for example, when a plurality of notification points are arranged at short intervals on the road, it is possible to prevent a message prompting safe driving from being repeatedly output in a short cycle.

  Further, in step S201, the position detection unit 32 detects the direction in which the output device 30 is traveling on the road by using GPS and / or a gyro, etc., and the output unit 33 detects the notification point in step S203. If the traveling direction on the existing road matches the traveling direction detected by the position detection unit 32, a message for prompting safe driving may be output.

  More specifically, the output unit 33 recognizes the traveling direction on the road where the notification point exists by referring to the flag indicating the traveling direction of the road where the notification point exists, which is included in the notification point data. If the recognized traveling direction matches the traveling direction detected by the position detection unit 32, a message for prompting safe driving may be output.

  As another method, the position detection unit 32 may notify the control device 20 of information indicating the traveling direction together with the detected current position in step S102 of FIG. In addition, in step S103 of FIG. 6, when the extraction unit 23 of the control device 20 searches for candidates for notification points, notification points that exist only in one of the traveling directions on the road are notified in step S102. It is also possible to search by narrowing down to notification points that match the travel direction that has been made. Thereby, since the notification spot data transmitted to the output device 30 includes only the notification spot that matches the traveling direction detected by the position detection unit 32, the data amount of the notification spot data is reduced. Can do.

  When the traveling direction on the road where the notification point exists coincides with the traveling direction detected by the position detection unit 32, a message for prompting a safe driving is output. Nevertheless, it is possible to suppress the output of a message prompting safe driving for a notification point that exists only in the up lane.

  Further, in step S203, the output unit 33 refers to the control type for each notification point included in the notification point data, thereby changing the message for prompting safe driving for each control type corresponding to the notification point. Good. For example, when the output unit 33 is a notification point corresponding to a stop violation control, the output unit 33 outputs a message such as “Please pay attention to the stop sign” and when the output unit 33 is a notification point corresponding to a speed violation control. May output a message such as “Beware of Speed”. Thereby, it becomes possible to give a more specific alert to the user.

(For route guidance)
FIG. 8 is a flowchart illustrating an example of a processing procedure (with route guidance) performed by the control device 20. The flowchart shown in FIG. 8 is executed, for example, when the navigation function is activated and a route search is performed by the output device 30.

  First, the extraction unit 23 retrieves data corresponding to the current date and time from the control schedule information, thereby acquiring the enforcement target area and the enforcement type at the current date and time (S301). Subsequently, the search unit 24 searches for a route from the departure point to the destination specified by the user via the output device 30 (S302). Subsequently, the extraction unit 23 searches for candidates for notification points existing on the route (S303). Subsequently, the extraction unit 23 includes notification points corresponding to the type of notification point that is included in the enforcement target area and is associated with the enforcement type implemented in the enforcement target area, among the notification point candidates. Candidates are extracted as one or more notification points. Further, the extraction unit 23 transmits the notification spot data to the output device 30 (S304).

  As in step S103 of FIG. 6, the notification point data transmitted by the extraction unit 23 to the output device 30 includes, for example, the road coordinates of the road where the notification point position coordinates, the control type, and the notification point exist for each notification point. The ID and the type of road where the notification point exists may be included. When the notification point exists only in one of the traveling directions on the road, the notification point data further includes a flag indicating the traveling direction of the road where the notification point exists for each notification point. Also good.

  When there are a plurality of enforcement target areas and enforcement types acquired in step S301, the extraction unit 23 performs the processing procedure of step S303 and step S304 for each.

  In addition, in the extraction setting information, when “-” is set in the “notification point type” corresponding to the type of enforcement performed in the area subject to enforcement, that is, the type of enforcement performed in the area subject to enforcement is included in the map data. If the notification point is not a type that can identify the notification point, the extraction unit 23 omits the processing procedure of step S304 for the control type (not extracting the notification point).

  The processing procedure performed by the output device 30 when performing route guidance is the same as that in which the step S204 is replaced in the flowchart of FIG. . In the case of performing route guidance, the output unit 33 includes a notification point in the vicinity of the stop point (for example, a predetermined range centered on the stop point) in the route guide for the notification point corresponding to the parking violation control. A message prompting safe driving may be output.

  The embodiments described above are for facilitating the understanding of the present invention, and are not intended to limit the present invention. The flowcharts described in the embodiments can be switched in order as long as there is no contradiction in processing. In addition, each element included in the embodiment and its arrangement, material, condition, shape, size, and the like are not limited to those illustrated, and can be appropriately changed. In addition, the structures shown in different embodiments can be partially replaced or combined.
