Description

  The present invention relates to a system that assists driving by providing information on traffic monitoring activities to a driver.

  Conventionally, a driving support system that stores position information of a target to be detected and that can detect the position of a vehicle by GPS is known. According to this driving support system, when the position of the vehicle and the position of the target have a predetermined positional relationship, an alarm can be issued to the driver. Examples of the target include a device for measuring a vehicle speed and a control / checking area. When the distance to a target reaches a set distance, a driving support system that displays information about the target on a display or outputs an alarm by voice has been proposed (for example, see Patent Document 1).

  In many cases, a target to be alerted, such as a speed measurement device or a check area, is installed in a dangerous place where a traffic accident is likely to occur. If the approach to the target is warned, it is possible to inform the driver of approach to a dangerous place where a traffic accident is likely to occur and to encourage safe driving. The driving support system configured as described above can motivate the driver to drive safely by alerting him to approaching a target, and is a meaningful system for promoting traffic safety.

  The monitoring points and monitoring periods for traffic monitoring activities conducted by the police to promote safe driving, such as controlling or checking mobile orvises, are unspecified and irregular, unlike the speed measurement devices installed as infrastructure equipment. is there. Regarding such a traffic monitoring activity, a place where the traffic monitoring activity was performed in the past may be stored as a target. In this case, when the vehicle approaches the place, information on the traffic monitoring activity can be provided to the driver. Traffic monitoring activities are often conducted at locations where traffic accidents are likely to occur. If the approach to such a point is warned, the driver can be encouraged to drive safely, and the possibility of an accident or the like can be suppressed.

  Police in each prefecture may publish traffic control information on traffic monitoring activities scheduled to take place within their jurisdiction. The purpose of disclosing traffic control information is, for example, to suppress drunk driving by disclosing the schedule of a drinking checkup at a time when drinking opportunities increase, such as at the end of the year. In recent years, a driving support system that acquires and reports such traffic control information has been proposed.

  In traffic control information released by police in each prefecture, prefectures, municipalities, jurisdiction units of police, routes, etc. are often designated as target areas for traffic monitoring activities. Among the driving support systems that report such traffic control information, there is a system that stores traffic control information for each prefecture and sets in advance which prefecture of traffic control information to report. For example, when the power supply is started by starting the engine or the like, the driving support system notifies the public control information of the preset prefectures such as the location of the home.

JP 2011-22161 A

  In a conventional driving support system that notifies the public control information of the prefecture where the home is located, the public control information of the prefecture including the position of the home is notified even when the user goes to a place far away from the home. Will be. As long as the driving support system is located in the same prefecture as the home, all the public information of the prefecture is reported, including traffic monitoring activities carried out at points and areas considerably away from the home. If the traffic control information at a distant place with little connection to the driver is included, the amount of information to be notified becomes excessive, and for example, important information regarding traffic monitoring activities performed near the home may be overlooked.

  It is an object of the present invention to provide a driving support system or the like that appropriately informs a driver of traffic control information and the like published by police in each prefecture.

One embodiment of the present invention is a driving support system that reports information that supports driving of a vehicle, and acquires monitoring schedule information related to an execution schedule of a traffic monitoring activity and current information that is information about the current,
At the notification timing determined based on the monitoring schedule information and the current information,
Control means for executing control for notifying information (referred to as notification information) based on the current information and the monitoring schedule information,
The notification timing includes a timing under a situation (hereinafter, referred to as an advance situation) in which the current information does not match the monitoring schedule information and the situation is set to a prior situation for the traffic monitoring activity. In the system (1).

  One embodiment of the present invention resides in a driving support program for causing a computer to realize the function as the driving support system (18).

  The driving support system according to the present invention performs notification of the notification information based on the current information and the monitoring schedule information at the notification timing determined based on the current information and the monitoring schedule information. This driving support system does not report the monitoring schedule information as it is, but reports the notification information based on the current information and the monitoring schedule information. For example, the notification information based on the current information reflecting the driving situation such as the current position, the current time, and the vehicle speed can be useful information for the driver to be notified.

  The notification timing includes a timing under the prior situation where the current information does not match the monitoring schedule information and is set to a prior situation for the traffic monitoring activity. If the timing under the prior situation is set as the notification timing, the notification information can be notified to the driver to be notified at an appropriate timing. By notifying the notification information at such a notification timing, for example, in a preliminary situation where the current information does not match the monitoring schedule information, a traffic monitoring activity that is not currently being performed but may be related to the driver is performed. The driver's attention can be directed to motivate safe driving.

  On the other hand, if such notification information is to be notified only in advance, it is possible to avoid presenting information that has little to do with the driver. If the amount of information to be notified is suppressed by avoiding the notification of the information having little relation in this way, the driver's attention level for the information to be notified can be kept high. If the alert level for the notification information is maintained at a high level, the notification information can be prevented from being missed, and the driver or the like can be recognized with high certainty. The notification effect of the notification information can be improved, and the awareness of safe driving can be improved with high certainty.

  As described above, the driving support system according to the present invention is a system capable of appropriately notifying the driver of information based on monitoring schedule information such as traffic control information published by police in each prefecture.

  In the present invention, the meaning that the current information does not match the monitoring schedule information means that the situation specified by the current information does not correspond to the target of the traffic monitoring activity specified by the monitoring schedule information. Good. As the case where the current information does not match the monitoring schedule information, for example, when the current date specified by the current information does not belong to the monitoring period of the traffic monitoring activity specified by the monitoring schedule information, and If the current position specified by the current information is far from the monitoring point where the traffic monitoring activity specified by the monitoring schedule information is performed, or the current time specified by the current information is specified by the monitoring schedule information It is recommended that the traffic surveillance activity is not included in the traffic monitoring activity.

In the driving assistance system according to a preferred aspect of the present invention, the current information includes driving information indicating a situation of the vehicle or a situation around the vehicle (2).
The driving information indicating the situation of the vehicle includes, for example, vehicle information such as vehicle speed, acceleration, turn signal (direction indicator) operation information, and seat belt wearing information. The vehicle information further includes, for example, an OBD (On-board Diagnostics) -II (II is a Roman numeral "2"; hereinafter, referred to as "OBD") standard which is a vehicle inspection standard. Various types of vehicle information obtained via the provided OBD connector may be included.

  For example, a situation where the vehicle speed is high can be determined as a prior situation for a traffic monitoring activity such as speed control. For example, if the notification information based on the scheduled monitoring information of the past speed control by the mobile orvis or the like is notified, the driver can be made aware of the speed limit, and the driver can be encouraged to drive safely according to the speed limit. For example, a situation in which a seat belt is not worn may be determined to be a prior situation for a traffic monitoring activity such as an inspection. If the notification information based on the monitoring schedule information such as the past traffic safety week and the check is notified, the driver can be encouraged to wear the seat belt.

  The driving information indicating the situation around the vehicle includes information that the vehicle is traveling ahead, that there is a vehicle approaching from behind, that there is a vehicle running alongside, and that the traffic signal in front is red. There are various types of information, such as information that there is a pedestrian crossing ahead, that there is a pedestrian in front of the pedestrian, information that darkness has occurred in the evening, and that rain has fallen. These pieces of information can be acquired by, for example, detection sensors such as a millimeter wave radar, a laser radar, an ultrasonic sonar, an imaging camera, a raindrop sensor, an illuminance sensor, and an infrared sensor.

In the driving support system according to a preferred aspect of the present invention, the monitoring schedule information includes, in addition to the first monitoring schedule information in which a monitoring period during which a traffic monitoring activity is performed is set in the future ahead of the present. Contains second monitoring schedule information in which the monitoring period during which the traffic monitoring activity is performed is set in the past before the present,
In the control means, a status having a predetermined association with the current information is set as the prior status regarding the second monitoring schedule information (3).

  For example, one of the purposes for the police and others to announce the schedule of traffic monitoring activities is to raise awareness of traffic safety. If the second monitoring schedule information on past traffic monitoring activities is notified, not only traffic monitoring activities scheduled to be implemented but also past traffic monitoring activities can be effectively used to raise the driver's awareness of safe driving. .

  As the situation having a relationship with the current information, for example, if the traffic monitoring activity is a seat belt enforcement, the situation when the information specifying the engine start is acquired as the current information, or the operation is started after the engine is started. It is preferable to set the situation after a predetermined time (for example, 1 minute in summer or 5 minutes in winter when warm-up is required) that is assumed as a time until the time elapses. For example, if the traffic monitoring activity is drinking control, for example, the current time after 6:00 pm together with information indicating that the vehicle is traveling in a direction away from the downtown area is acquired as the current information. It is good to have the situation that has. For example, if the traffic monitoring activity is an intersection-related control, a situation in which information indicating that the vehicle has stopped at an intersection is acquired as current information may be a situation having a relationship with the current information.

In a driving support system according to a preferred aspect of the present invention, the monitoring schedule information includes information regarding a monitoring period during which a traffic monitoring activity is performed, while information regarding a current date and time is acquired as the current information. ,
The prior situation is based on a monitoring period in which the traffic monitoring activity is performed, and a condition of temporal proximity that the current time belongs to a predetermined time range excluding the monitoring period is satisfied. This is the situation (4).

  The predetermined time range may be a time range ahead of the future when the monitoring period is used as a reference. Further, the predetermined time range may be a time range before the past when the monitoring period is set as a reference. The case where the current date and time belongs to a time range earlier than the monitoring period may be, for example, a case where the monitoring period has already ended and is in the past. The case where the current date and time belongs to a time range before the monitoring period may be a case where the monitoring period is a future period earlier than the present and the traffic monitoring activity is not performed.

In the driving support system according to a preferred aspect of the present invention, the monitoring schedule information includes, in addition to the first monitoring schedule information in which a monitoring period during which a traffic monitoring activity is performed is set in the future ahead of the present. Contains second monitoring schedule information in which the monitoring period during which the traffic monitoring activity is performed is set in the past before the present,
As the predetermined time range with respect to the first monitoring schedule information, a range on a side that goes back in time from the monitoring period is set,
As the predetermined time range for the second monitoring schedule information, a range in which time elapses with respect to the monitoring period is set (5).

  If the notification information based on the second monitoring schedule information on the past traffic monitoring activity is notified in addition to the first monitoring schedule information, the driver can use the past traffic monitoring activity to make the driver aware of safe driving. Can be uplifted. At that time, reporting information on past traffic monitoring activities unrelated to the driver has little effect.However, in a prior situation involving the driver, raising the driver's awareness of safe driving by reporting is provided. Can be.

In the driving support system according to a preferred aspect of the present invention, the predetermined time range may have a different range for each type of traffic monitoring activity (6).
For example, a longer range may be set for traffic monitoring activities with a high degree of driver interest, such as speed control, while a shorter range may be set for general traffic monitoring activities, such as a traffic safety campaign.

In a driving support system according to a preferred aspect of the present invention, the monitoring schedule information includes position information indicating a monitoring point or a monitoring area where a traffic monitoring activity is performed,
The prior situation is that the current position of the vehicle, which is one of the current information, does not match the monitoring point or the monitoring area, but the current position is a predetermined position relative to the monitoring point or the monitoring area. It is a situation where the condition of spatial proximity of being within a certain range is satisfied (7).

  When the current position is located outside the monitoring point or the monitoring area, the prior situation can be determined, whereby the notification information can be notified. If the notification information is notified in a prior situation where such spatial proximity is satisfied, it is possible to notify at an early stage that may approach the monitoring point of the traffic monitoring activity, and the driver for safe driving can be provided. You will be able to elevate your awareness of it early. If the notification is issued at an early stage, it is possible to suppress the loss of the notification information and the like, and it is possible to make the driver recognize with high certainty.

In the driving assistance system according to a preferred aspect of the present invention, area information indicating a sectioned area where the land is sectioned is stored,
As the predetermined positional range, at least one of other division areas adjacent to the division area is set instead of the division area including the monitoring point or the monitoring area (8).
In this case, a positional range for judging a prior situation can be set in units of the section area. The adjacent area other than the area including the monitoring point or the like is the target of the prior situation. As the division area, for example, various areas such as prefectures, municipalities, and territories within each prefecture can be set.

In a driving support system according to a preferred aspect of the present invention, a route that passes through the monitoring point or a route that partially belongs to the monitoring area is specified using route information that indicates a route on which the vehicle can travel, and the predetermined route is specified. (9).
If a route that passes through a monitoring point, or a route that partially belongs to the monitoring area, is set as the predetermined positional range, the driver who is driving the route will be at an early stage at an early stage of being located far away. Notification becomes possible.

In a driving support system according to a preferred aspect of the present invention, a link that indicates a connection relationship between different routes is used to connect to the route in addition to a route that passes through the monitoring point or a route that partially belongs to a monitoring area. Another route is specified and set as the predetermined positional range (10).
If a route that passes through the monitoring point or a part of the route that belongs to the monitoring area is set in addition to a route that belongs to the monitoring area, it is possible to notify at an early stage that there is a possibility of entering the route that passes through the monitoring point. become.

  For example, a route that passes through the monitoring point or a route that partially belongs to the monitoring area may be set as the predetermined positional range among routes calculated by a route calculation function of a navigation device or the like. The route calculated by the route calculation function is a route that is highly likely to travel thereafter. If this route is set within a predetermined positional range, when a monitoring point or the like exists on the route or passes through a monitoring area, the notification can be executed from an early stage at a long distance.

As the prior situation in the driving assistance system according to a preferred aspect of the present invention, a different situation is set for each type of traffic monitoring activity (11).
For example, for the seat belt control, the ignition-on state is set as the pre-condition, and for the speed control, the time when the vehicle speed exceeds a predetermined speed is set as the pre-condition. It is also good to change the setting of the advance situation.

In the driving assistance system according to a preferred aspect of the present invention, a part of the current information is information acquired by a detection sensor provided with a detection area toward the outside or inside of the vehicle (12).
Examples of the detection sensor include an occupant sensor for detecting an occupant in a vehicle, an in-vehicle camera for photographing the inside and outside of the vehicle, a radar device and a sonar for monitoring the front and surroundings, and the like.

In the notification of the notification information in the driving assistance system according to a preferred aspect of the present invention, the notification mode differs depending on whether the notification is a notification regarding a traffic monitoring activity to be performed or a notification regarding a traffic monitoring activity that has been performed ( 13).
In the notification of the notification information in the driving assistance system according to a preferred aspect of the present invention, the notification mode is determined based on whether the notification is a notification related to a traffic monitoring activity that is being performed or a notification that is related to a scheduled or completed traffic monitoring activity. Different (14).
In these cases, the type of the notification information can be immediately determined according to the notification mode, and the notification that is easy for the driver to understand becomes possible. The notification information can be recognized with high certainty even during driving, and the loss of the notification information can be suppressed.

A driving support system according to a preferred aspect of the present invention includes a collection unit that collects information regarding an execution schedule of a traffic monitoring activity that is electronically disclosed via a communication line and generates the monitoring schedule information ( 15).
By automatically generating the monitoring schedule information, the cost for generating the monitoring schedule information can be suppressed.

A driving support system according to a preferred aspect of the present invention includes a computer device including the collection unit,
In-vehicle equipment comprising the control means,
The in-vehicle device uses the monitoring schedule information generated by the computer device (16).
The monitoring schedule information generated by the computer device can be taken into a vehicle-mounted device via a storage medium such as a memory card or wireless communication such as WiFi or Bluetooth.

A driving support system according to a preferred aspect of the present invention includes an in-vehicle device including the collection unit and the control unit (17).
In this case, there is no need to perform any operation for transferring the monitoring schedule information from the external device to the on-vehicle device. A very convenient and useful device can be realized as a stand-alone device.

There are a digital radio signal, a radio signal used in an automobile mobile phone system dedicated to police, a radio signal transmitted from an emergency vehicle, and the like.

  The wireless receiving unit 12 may be a receiving unit including a plurality of wireless modules that individually receive wireless signals of different frequencies. When receiving the wireless signal, the wireless receiving unit 12 detects the signal level of the received wireless signal, and outputs the signal level as Received Signal Strength Indication (RSSI). The control unit 11 recognizes the signal level of the wireless signal based on the voltage level of the RSSI output from the wireless receiving unit 12 and can estimate the distance between the target object of the wireless signal transmission source and the host vehicle. is there.

  The GPS receiver 13 is a wireless module for receiving a wireless signal transmitted from a GPS satellite. The GPS receiver 13 detects and outputs position information of the own vehicle based on the received wireless signal. The position information is the latitude and longitude of the own vehicle position (current position of the vehicle). The control unit 11 specifies the own vehicle position based on the position information output from the GPS receiving unit 13. Further, the GPS receiver 13 of the present example outputs the moving speed as the vehicle speed.

  In the driving support system 1 of the present example, various information that can be obtained by the control unit 11 is handled as current information representing driving information such as a situation of the vehicle and a situation around the vehicle. The current information includes a current date and time indicating a current date and time by an RTC (real-time clock), various types of reception information output by the wireless reception unit 12, position information and vehicle speed output by the GPS reception unit 13, and the like.

Further, detection signals from various detection sensors such as an occupant detection sensor mounted on the vehicle, a millimeter wave radar, a front camera, an ultrasonic sonar, and a peripheral camera can be captured and handled as current information.

The display unit 14 includes, for example, a liquid crystal display, an EL display, and the like. The display unit 14 displays a desired image under the control of the control unit 11.
The speaker 15 outputs a desired sound under the control of the control unit 11.
The card reader 17 is an interface for accessing the SD card 171. The control unit 11 can read information stored in the SD card 171 via the card reader 17.

  The storage unit 16 is a nonvolatile storage element that stores various information. The storage unit 16 includes, for example, an EEPROM, a flash memory, a hard disk drive, and the like. The storage unit 16 stores map data, image data displayed on the display unit 14, sound data output from the speaker 15, various databases, and the like. The various databases include at least a first DB and a second DB described below.

  The first DB is a database that stores polygon data capable of specifying an administrative section based on position information. For example, the administrative division is determined for each municipalities smaller than the prefecture unit. Hereinafter, an area represented by an administrative section is also referred to as a section area. Area information for identifying a section area is associated with the polygon data.

  The control unit 11 refers to the first DB based on the position information output from the GPS receiving unit 13 to specify area information for identifying a partitioned area where the vehicle is located in units of municipalities. In addition, the area represented by the division area is not limited to the municipalities. The division area may represent another area such as an area under the jurisdiction of the police of each prefecture or an area of the prefecture.

  The second DB is a database that stores information on a target to be notified to the driver (referred to as a notification target as appropriate). As the target, for example, a speed measuring device, a speed limit switching point, a control area, a check area, a banned monitoring area, an N system, a traffic monitoring system, an intersection monitoring point, a signal ignoring suppression system, a police station, an accident-prone area, a car High aim frequent occurrence area, steep / continuous curve (highway), branching / merging point (highway), ETC lane advance guidance (highway), service area (highway), parking area (highway), parking area (highway) Road), highway oasis (highway), smart interchange (highway), gas station in PA / SA (highway), tunnel (highway), highway radio reception area (highway), prefectural border announcement, road station, There is viewpoint parking etc. Note that the above-described speed measuring device includes a speed measuring device that emits a radar wave (microwave) such as a radar, a speed measuring device that does not emit a radar wave such as a loop coil, and the like.

  The second DB includes information indicating the type of the notification target, information on the latitude and longitude indicating the position of the notification target, data of a schematic diagram or photograph displayed on the display unit 14, data of a sound output from the speaker 15, and the like. Is stored in association with each target. The control unit 11 specifies the notification target near the host vehicle by referring to the second DB based on the position information output from the GPS receiving unit 13.

  The first DB and the second DB are stored in the storage area of the storage unit 16 in advance at the time of product shipment. After the product is shipped, the data in the first DB and the second DB can be updated using a known method. As a data updating method, for example, there is a method using an SD card 171 storing a first DB and a second DB. If the first DB and the second DB are read from the SD card 171 set in the card reader 17 and stored in the storage unit 16, the data can be updated. Further, for example, there is a data update method using various communication functions such as an infrared communication function of the driving support system 1. By executing the infrared communication with the external device, the updated first DB and second DB are acquired, and stored in the storage unit 16, whereby the data can be updated. Note that it is also possible to acquire only the difference data between the old first DB and the like and the new first DB and update the data.

  The SD card 171 stores a third DB in which a plurality of pieces of monitoring schedule information related to traffic monitoring activities are stored. The traffic monitoring activity is information on a traffic monitoring activity that is performed irregularly at an unspecified place in order to promote safe driving, and includes, for example, police enforcement and checkups performed by the police. In the driving support system 1 of the present example, the details of the traffic monitoring activity related to the own vehicle are specified by referring to the third DB.

  The detailed data specification of the third DB will be described with reference to the example of FIG. In the figure, each piece of information stored in indexes 1 to 15 is monitoring schedule information. The monitoring schedule information is information based on public control information published via the homepage (hereinafter, referred to as HP) of each prefectural police nationwide. The monitoring schedule information is generated by converting the disclosure control information into data in a predetermined format. In particular, in the monitoring schedule information stored in the third DB of the present example, the monitoring period is set in the future ahead of the present in addition to the monitoring schedule information corresponding to the monitoring period in which the traffic monitoring activity is performed. The first monitoring schedule information and the second monitoring schedule information for which the monitoring period has been set in the past before the present are included.

  The monitoring schedule information includes the "prefecture", "start date", "start time", "end date", "end time" where traffic monitoring activities are performed, "jurisdiction" police stations that perform traffic monitoring activities, And "display content" which is text-based notification information. For example, in FIG. 2, the information of the index 2 indicates that the enforcement of the Iwate Prefectural Police under the jurisdiction of the Iwate Prefectural Police from 12:00 to 18:00 on March 7, 2011 in any area in Kuzumaki Town. Means. “302” of “implementation place” is area information for specifying a city, town, or village.

  In the “execution place” of the monitoring schedule information, area information for identifying a division area in units of municipalities is stored. For example, if the information published as the place where the traffic monitoring activity is implemented spans multiple municipalities such as "prefectural roads", all the area information for identifying the relevant municipalities is " It is said. For example, in the third DB of FIG. 2, the monitoring schedule information of the index 5 at which the traffic monitoring activity is performed on “prefectural road” includes the area information “302 (Kuzumaki-cho)”, “501 (Karumai-cho)”, and “209 ( (Ichinoseki)) is included in the “implementation site”, which is the monitoring point. As described above, when the traffic monitoring activity is disclosed over a wide area, a plurality of area information is included in the monitoring schedule information. By configuring such monitoring schedule information, an area (monitoring area) where the traffic monitoring activity is performed can be specified with high reliability.

  In the driving support system 1 of this example, since polygon data capable of specifying area information in units of municipalities is stored in the first DB, the area information of the partitioned area where the vehicle is located is stored based on these polygon data. Specify by unit. Both the area information of the partitioned area where the vehicle is located and the area information associated with the monitoring schedule information as the “implementation place” are in municipalities. For example, the same area and the adjacent area as the divisional area where the vehicle is located can be uniformly searched from the “implementation place” in the monitoring schedule information, so that the traffic monitoring activity conducted near the vehicle is performed. Monitoring monitoring information can be easily specified.

  For example, the public enforcement information is published in units of localities where the traffic monitoring activities are carried out, such as "~ Jurisdiction" for Prefectural Police, "~ Area" for Prefectural Police, and "Along Route ~" for Prefectural Police. Suppose it was done. In this case, in the public control information, the unit of the area where the traffic monitoring activity is carried out differs for each of the prefectural police as the publication sources. According to the driving support system 1 of the present example, even in such a case, it is possible to associate the area information in units of municipalities with the monitoring schedule information for the public control information announced by all prefectural police. , And can be used in a unified manner as an “implementation place”. As a result, the driving support system 1 of the present example can unified, accurately, and easily specify the monitoring schedule information regarding the traffic monitoring activity performed in the section area where the vehicle is located. For example, even if the area where the traffic monitoring activities are performed is abstractly announced, such as "Along the Route No." or "The area", information on the traffic monitoring activities performed near the vehicle can be reliably obtained. Highly specific.

  In the “display contents” that constitute the monitoring schedule information, information about traffic monitoring activities is stored as text information. The notification information stored in the “display content” is used as it is as a message displayed on the display unit 14 (see FIG. 1). In the part surrounded by [] in the notification information, a category indicating the type of the traffic monitoring activity is stored. The wording of the notification information of "display contents" has a single sentence structure of "what," "when," and "where," so that the contents can be grasped even while looking at the hand while driving. The information of “what” is information indicating the content of the enforcement, such as “speeding violation”, “drinking”, and “pause”. The “when” information is information indicating a time zone and a date when the traffic monitoring activity is performed. The “where” information is, for example, information indicating an address or a route where the traffic monitoring activity is performed.

The control unit 11 displays a message based on the notification information of “display content” on the display unit 14 at a predetermined notification timing by telop. As will be described in detail later, in the driving support system 1 of the present example, the notification timing is determined based on the monitoring schedule information and the current information.
The notification information displayed as a telop as a message includes the type of traffic monitoring activity ("what"), the period during which the traffic monitoring activity is performed ("when"), and the area where the traffic monitoring activity is performed ("where ")It is included. If there is a telop display of the message, for example, the driver or the like can recognize the priority item of the regulation as the type of the traffic monitoring activity. The priority items of the control include, for example, overspeeding, overloading, seatbelts, drunk driving, ignoring signals, and the like. Further, for example, a driver or the like can recognize a police jurisdiction, a route, a municipality, and the like as an area where the traffic monitoring activity is performed. If the message as described above is displayed as a telop, the driver can be informed of the notification information in detail, and it is possible to motivate a safe driving that pays particular attention to these points.

  Here, an example of a method of generating monitoring schedule information stored in the third DB will be described. The monitoring schedule information is generated by, for example, an operator or the like converting data of public control information published via HP of prefectural police throughout the country. When converting the monitoring schedule information into data, as shown in FIG. 2, the date of execution, time zone, location, type, etc. are extracted from the disclosure control information with the same language as much as possible, and the notification information as text information is associated with the information. Can be Since the public control information is published via the HP of each prefectural police, it is scheduled monitoring information for each prefecture as illustrated in FIG. Each piece of information is one for each date, time zone, jurisdiction, municipalities, or regulatory type. In consideration of the limitation of the storage capacity of the SD card 171, the monitoring schedule information is simply converted into data. Note that, depending on the disclosure control information, a specific item of the storage information of the third DB may not be disclosed. Unpublished items are not converted to data, but become empty data. Note that the items associated with the monitoring schedule information are not limited to the above example. In order to improve the generation efficiency of the information stored in the third DB, the respective items may be put together.

  The third DB including the monitoring schedule information generated by converting the disclosure control information into data can be downloaded from the dedicated HP on the user side. The contents of the downloaded third DB are stored in the SD card 171. The control unit 11 selects and reads out the monitoring schedule information to be notified from the monitoring schedule information stored in the third DB.

  The monitoring schedule information to be selected includes, first, the own vehicle position and the current time with respect to the monitoring schedule information such as “start date”, “start time”, “end date”, “end time”, and “implementation place”. There is monitoring schedule information whose current information matches. Furthermore, the monitoring schedule information in which the current information such as the own vehicle position and the current time does not match the monitoring schedule information, but the current information is determined to be in the “advance situation” of the traffic monitoring activity is also selected. The details of the specific contents of the “prior situation” and the process of displaying a message generated based on the selected and read monitoring schedule information on the display unit 14 will be described later.

  Next, a display screen 20, which is an example of a display screen displayed on the display unit 14, will be described with reference to FIG. On the display screen 20, a main display area 21, a first sub-display area 22, and a second sub-display area 23 are arranged. The main display area 21 is an area for displaying an image for indicating a positional relationship between the host vehicle and the notification target. The first sub-display area 22 is an area for displaying the name of the partitioned area where the vehicle is located. The second sub-display area 23 is an area for displaying a message regarding a traffic monitoring activity.

The main display area 21 includes an area 211 for displaying a map image, an area 212 for displaying the type of the notification target and the distance to the notification target, an area 213 for displaying the traveling speed of the vehicle, a display mode and the current time. Region 214 and the like are arranged.
The map image is an image generated by reading map data around the own vehicle position from the storage unit 16. The range of the map image displayed in the area 211 of the main display area 21 is determined according to the setting by the driver. On the map image displayed in the area 211, the own vehicle icon 31 and the target icon 32 are displayed in a superimposed manner. The host vehicle icon 31 is an icon display for indicating the position of the host vehicle with respect to the map image. The control unit 11 specifies the own vehicle position based on the position information output from the GPS receiving unit 13 and displays the own vehicle icon 31 on the map image in a position corresponding to the own vehicle position.

  The target icon 32 is an icon display for indicating the position of the notification target on the map image. The graphic displayed inside the target icon 32 indicates the type (category) of the notification target. The control unit 11 specifies the position of the notification target based on the second DB, and displays the target icon 32 over the portion corresponding to the position of the notification target in the map image. The type of the notification target and the distance to the notification target are displayed as text in the area 212.

  When the distance from the host vehicle to the notification target becomes smaller than a predetermined distance, the control unit 11 reads the schematic diagram or photograph data from the second DB according to the type of the notification target, and displays the data on the map image in a superimposed manner. I do. Further, audio data corresponding to the notification target is read from the second DB and output from the speaker 15. For example, when the speed measuring device approaches less than 500 m, the schematic diagram or photograph data of the speed measuring device is read out from the second DB and displayed on a map image, and "Speed measuring device 500 m ahead. The voice is read from the second DB and output from the speaker 15.

  The control unit 11 determines whether or not the notification target is near the host vehicle based on the RSSI voltage level output from the wireless reception unit 12. The RSSI signal level increases in proportion to the strength of the wireless signal received by the wireless receiving unit 12. The control unit 11 determines whether or not the distance from the host vehicle to the notification target has become smaller than a predetermined distance based on the threshold determination regarding the RSSI. When the control unit 11 determines that the distance has become smaller than the predetermined distance, the control unit 11 reads the schematic diagram or photograph data from the second DB according to the type of the notification target object and displays the data on the map image. Further, the audio data corresponding to the notification target is read from the second DB and output from the speaker 15. For example, when an emergency vehicle approaches within a predetermined distance, data of a schematic diagram or a photograph of the emergency vehicle is read out from the second DB and displayed overlaid on a map image, and a voice of “emergency vehicle. And output from the speaker 15.

  The driving support system 1 of the present example that operates as described above can notify the driver that the notification target exists near the host vehicle. By visually recognizing the main display area 21, the driver can recognize the notification target near the host vehicle. If the driver is notified of the approach to the notification target, which is often installed in a dangerous place where a traffic accident is likely to occur, it is possible to encourage safe driving when approaching the dangerous place.

  Since the map image is displayed in the main display area 21, the driver can grasp the geographical information around the own vehicle. For example, the driver can reduce the traveling speed in advance and sufficiently pay attention to the surrounding environment in advance by grasping the surrounding road environment. As described above, the driving support system 1 of the present example can present information necessary for safe driving of the driver to the driver together with a message of the notification information.

  The control unit 11 aligns the own vehicle icon 31 and the target icon 32 displayed in the area 211 of the main display area 21 with the map image, and performs display while synchronizing. The display position of the vehicle icon 31 is fixed to a lower central portion of the area 211. The direction of the map image is set so that the traveling direction of the vehicle is on the upper side. When the traveling direction of the host vehicle changes (turns), the map image rotates accordingly. When the host vehicle moves forward, the map image scrolls downward (so-called heading-up display). Note that such display control is realized using map display control in a car navigation system, that is, control for appropriately scrolling a map image in a state where the position of the vehicle is fixed at the center of the screen.

  In the first sub-display area 22, the name of the partitioned area where the vehicle is located is displayed. The control unit 11 specifies the area information of the partitioned area where the vehicle is located by referring to the first DB based on the position information output from the GPS receiving unit 13. The name of the divided area corresponding to the specified area information is displayed in the first sub display area 22. By visually recognizing the name displayed in the first sub display area 22, the driver can grasp the section area where the vehicle is located.

  In the second sub-display area 23, a message (broadcast information) as broadcast information related to the traffic monitoring activity is displayed. This message is text-based notification information generated based on the monitoring schedule information stored in the third DB stored in the SD card 171. The message includes information such as the enforcement date, time, enforcement type, enforcement location (route, jurisdiction, etc.). In addition, since there is a slight difference in the content of the public control information published by each prefectural police, the displayed content is different depending on the prefecture. When the number of pieces of notification information included in the message becomes two or more and the number of characters of the message increases, the control unit 11 causes the message to flow in a telop and displays the message in the second sub-display area 23.

  A specific example of a message displayed in the second sub display area 23 will be described with reference to FIGS. As shown in the figure, the message 41 includes a plurality of phases (a first phase 42 and a second phase 43) that are divided for each category of the monitoring schedule information. The first phase 42 and the second phase 43 include one or more pieces of notification information. When a plurality of pieces of broadcast information are included in one phase, they are arranged in order. In FIG. 4, “XX information” and “Δ information” correspond to the notification information of each case. At the beginning of each phase, a title indicating an overview of the broadcast information is added.

  As described above, the message displayed in the second sub-display area 23 is information created by classifying a plurality of pieces of notification information to be notified to the driver for each type (category). According to this message, the notification information on the traffic monitoring activity can be distinguished for each category and made to be recognized by the driver. The number of characters that can be registered in one phase is limited to, for example, 128 double-byte characters (256 bytes in terms of bytes). Setting such a limit on the number of characters makes it easier for the driver to grasp the contents while driving.

  When the number of characters registered in one phase exceeds 128 characters, the broadcast information is classified into more detailed categories. For example, in FIG. 5, the first phase is titled “<< Public Control Information Aichi Prefectural Police >>” and the second phase is titled “<< Traffic Regulation Information Aichi Prefectural Police >>”. I have. In the first phase, information on “regulation” (corresponding to the monitoring schedule information of the indexes 2 and 3 in FIG. 2) is stored.

  Generally, when visually recognizing the display unit 14 during driving, it is difficult for the driver to keep watching the display unit 14 for a long time. Therefore, if many messages are displayed on the display unit 14 at once, there is a possibility that a driver or the like may not be able to recognize the messages accurately. On the other hand, in the driving support system 1 of the present example, by scrolling and displaying messages that do not fit in the second sub-display area 23, the amount of information displayed at a time is suppressed, and the above-described problem is prevented. Avoided. In the driving support system 1, the message, which is the notification information created based on the monitoring schedule information, is divided into categories and is scroll-displayed in the second sub-display area 23. Thereby, the amount of information of the message displayed at one time in the second sub-display area 23 can be suppressed, and the size of the displayed text can be increased. The driver can accurately recognize the message displayed on the second sub-display area 23 even when the driver repeatedly looks at the display unit 14 at short intervals during driving.

  For example, when the message 41 shown in FIG. 4 is displayed in the second sub-display area 23, the first phase 42 (title, XX information (first case), XX information (second case)) is displayed in the second phase. The scroll display is sequentially performed on the sub-display area 23, and when all the scroll displays of the first phase 42 are completed, the second phase 43 is entered. If there are no remaining phases, the scroll display is repeated sequentially from the first phase 42. Since the scroll display is repeatedly performed a plurality of times, the driver can recognize the repeatedly displayed message even if the message is once overlooked.

  Note that the title of the first phase 42 of the message is first displayed in the second sub-display area 23, and at the same time, an alarm sound (pyro lean, pyrro lean) is output from the speaker 15. Thus, the driver can be notified that the message as the notification information is displayed in second sub-display area 23.

  When the divided area where the vehicle is located changes in accordance with the traveling of the vehicle and the message displayed in the second sub-display area 23 is updated, the speaker 15 similarly outputs an alarm sound. This allows the driver to recognize the updated message reliably by visually recognizing the display unit 14 when the notification is made by the alarm sound. In this way, the driving support system 1 can prevent the driver from overlooking the updated message.

  The control unit 11 changes the scroll speed when the message is scroll-displayed in the second sub-display area 23 according to the vehicle speed (running speed of the vehicle). For example, when the vehicle speed is high, it is possible to assume a driving situation in which it is not possible to continuously look at the display unit 14 for a long time. In such a case, the scroll speed of the message is reduced so that the driver can understand even a single sentence. As a result, the driver can reliably recognize the message within a short time. On the other hand, for example, when the vehicle speed is low, it is possible to assume a driving situation in which it is possible to look at the display unit 14 continuously for a relatively long time. In such a case, the scroll speed of the message is increased. As a result, the driver can recognize a large number of messages with high certainty. Further, while the vehicle is stopped, the scroll speed of the message is further increased so that various public control information can be viewed.

  Further, when displaying the message in the second sub-display area 23, the control unit 11 displays the message in a different display color depending on whether the target traffic monitoring activity is being performed, has been performed, or is to be performed. indicate. The message of the ongoing traffic monitoring activity is red, the message corresponding to the scheduled implementation is yellow, and the completed one is blue. Alternatively, for example, while the text display color is kept constant, the display mode may be changed by changing the background color of the second sub-display area 23, and the display mode is being implemented or will be implemented. It is also possible to provide a display lamp indicating whether the operation has been performed or not, and to change the display mode by turning on one of the display lamps during the message display.

  Since the name of the section area where the vehicle is located is displayed in the first sub-display area 22, the driver can recognize the message displayed in the second sub-display area 23 and the section area together. For example, when the traffic monitoring activity is performed over a wide area, the driver can confirm which part of the entire area where the monitoring activity is performed the position of the own vehicle. For example, it is assumed that a route is announced as an area where traffic monitoring activities are performed. It is assumed that the own vehicle has moved and the own vehicle has entered the defined area to which the announced route belongs. At this time, in the first sub-display area 22, the name of the partitioned area where the host vehicle is located is displayed. In the second sub-display area 23, a message including the announced route is displayed. By referring to the map image displayed in the main display area 21, the driver can easily specify the location of the route included in the message from within the section area having the name displayed in the first sub display area 22. It is possible to recognize the positional relationship between the vehicle and the route. By judging whether or not the vehicle is approaching the route, the driver can grasp a place where special attention should be paid to safe driving and continue driving.

  Next, a main process executed in the control unit 11 will be described with reference to FIG. When the driving support system 1 is powered on, the main processing is executed by the control unit 11 executing the program stored in the ROM. In response to the start of the main process, the control unit 11 first obtains the position information output by the GPS receiving unit 13 and specifies the latitude and longitude of the own vehicle position based on the position information. The own vehicle position is specified above (S101). Subsequently, based on the acquired position information, the control unit 11 refers to the first DB of the storage unit 16 to acquire the area information of the partitioned area where the vehicle is located (S102), and stores the area information in the RAM. Let it.

  The control unit 11 generates a map image of the surrounding area including the position of the own vehicle based on the map data stored in the storage unit 16. The map image is displayed in the area 211 of the main display area 21 of the screen of the display unit 14 (S103). The size of the map image displayed in area 211 is adjusted based on a condition set in advance by the driver. Subsequently, the control unit 11 displays the host vehicle icon 31 on the map image corresponding to the position corresponding to the host vehicle position specified in S101 (S104). By visually recognizing the map image and the host vehicle icon 31 displayed in the main display area 21, the driver can grasp the geographical information including the position of the host vehicle.

  The control unit 11 specifies the name of the partitioned area where the vehicle is located in units of municipalities based on the area information acquired in S102. The name of the partitioned area is specified by referring to a correspondence table between the area information and the name stored in the storage unit 16 in advance. The name of the specified partitioned area is displayed in the first sub-display area 22 of the screen of the display unit 14 (S105). By visually recognizing the name displayed in the first sub-display area 22, the driver can recognize the divided area where the host vehicle is located in units of municipalities.

  Subsequently, the control unit 11 specifies current information such as the current date and time (date and time) (S106). For example, the current date and time are obtained from a real-time clock (RTC) not shown. Subsequently, the third DB stored in the SD card 171 is read, and the monitoring schedule information stored in the third DB is referred to (S107). Then, based on the monitoring schedule information stored in the third DB read from the SD card 171, a message as notification information to be displayed in the second sub-display area 23 is generated as follows.

Among the monitoring schedule information stored in the third DB of the SD card 171, it is determined that the monitoring schedule information having the same current information as the own vehicle position (area information) and the current date and time, and the current information are in the “advance situation”. Select the monitoring schedule information to be monitored.
For example, when selecting the monitoring schedule information whose current information matches, first, the monitoring schedule information in which the same area information as the area information specified in S102 is associated as the “execution place” is extracted. The control unit 11 performs monitoring for performing a traffic monitoring activity based on “start date”, “start time”, “end date”, and “end time” (see FIG. 2) associated with the monitoring schedule information. A period is specified, and monitoring schedule information that satisfies the condition that the current date and time is included in the monitoring period is selected.
For example, when selecting the monitoring schedule information determined to be in the “advance situation” in which the temporal proximity is satisfied, first, the same area information as the area information (specified in S102) corresponding to the own vehicle position is selected. Extracts the monitoring schedule information associated with the “execution place”. The control unit 11 performs monitoring for performing a traffic monitoring activity based on “start date”, “start time”, “end date”, and “end time” (see FIG. 2) associated with the monitoring schedule information. A period is specified, and monitoring schedule information whose current date and time satisfies temporal proximity to the monitoring period is selected. The content of the temporal proximity will be described later in detail.
For example, when selecting monitoring schedule information that corresponds to another adjacent partitioned area and is determined to be in the “advance situation” where the spatial proximity is satisfied, first, each monitoring schedule information is selected. A monitoring period of the schedule information is specified, and monitoring schedule information in which the monitoring period includes the current date and time is extracted. The control unit 11 selects, as the monitoring schedule information that satisfies the locational proximity, the monitoring schedule information in which the area information of another partition area adjacent to the partition area to which the own vehicle position belongs is associated as the “execution place”. . The details of the locational proximity will be described later in detail.

  If the monitoring schedule information is not selected (S108: NO), the process returns to S101 without generating notification information (message) to be displayed in the second sub-display area 23. On the other hand, when one or more pieces of monitoring schedule information are selected (S108: YES), notification information to be displayed in the second sub-display area 23 is generated based on the monitoring schedule information as follows (S109). ).

  The control unit 11 sorts and arranges the selected monitoring schedule information for each type (category) of the traffic monitoring activity. At the beginning of the notification information arranged for each category, a title indicating the outline of each category is added. As the title, an optimal title is selected from a plurality of titles prepared in advance. The selection of the optimum title is performed, for example, as follows. A table in which titles and categories are associated with each other is stored in the storage unit 16 in advance. When the broadcast information is classified and arranged for each category, the title corresponding to each of the classified categories is specified by referring to the table stored in the storage unit 16. The specified title is added to the head of the arranged monitoring schedule information as the optimal title indicating the category. Thereby, each phase constituting the message is created and stored in the RAM.

  Subsequently, the control unit 11 specifies the vehicle speed (S110). In this example, the moving speed output by the GPS receiving unit 13 is treated as the vehicle speed. Instead, the identification may be performed based on an acceleration sensor (not shown) or based on OBD data acquired via an OBD connector on the vehicle side. The control unit 11 determines the scroll speed for scrolling the message generated in S109 according to the vehicle speed. Specifically, the scroll speed is determined so as to be inversely proportional to the vehicle speed. The control unit 11 scrolls and displays the message in the second sub-display area 23 at the scroll speed determined in this way (S111). According to such control, by recognizing a message in a short time such as "clicking on", the scroll speed is reduced in a state where the vehicle speed is high and the driver cannot visually recognize the display unit 14 for a long time continuously. Are sure. On the other hand, when the vehicle speed is low, the scroll speed is high, so that a large amount of messages (notification information) can be displayed. In a situation where the vehicle speed is low, the driver can visually recognize the display unit 14 continuously for a relatively long period of time, so that even if a large number of messages are displayed, the possibility of dropping or the like is low. When a message is scroll-displayed in the second sub-display area 23 for the first time, an alarm sound is output from the speaker 15.

  The control unit 11 determines whether or not the area information acquired in S102 has been changed with the movement of the vehicle. Whether or not the area information has been changed is determined based on whether or not the area information previously stored in the RAM and the area information stored this time are different. When the area information has been changed, the message created in S109 may be newly updated. Therefore, the control unit 11 determines whether the message created in S109 is newly updated (S112). Whether or not the message has been updated can be determined based on whether or not the message previously stored in the RAM differs from the message stored this time.

  If there is no change in the message created in S109 (S112: NO), the process returns to S10. On the other hand, if the message has been newly updated (S112: YES), an alarm sound is output from the speaker 15 (S122). By outputting the alarm sound in this manner, the driver's attention can be drawn to the second sub display area 23, and the driver can recognize the newly updated message with high certainty. In the driving support system 1 of the present example, oversight of a message updated by such a device is suppressed beforehand. After the output of the alarm sound, the process returns to S101.

  In the main processing, for example, a predetermined wait time (for example, one second) may be set when returning to S101 after S108, S112, and S122. Further, for example, in the main process, after S108, S112, and S122, the process may return to S101 when the traveling distance of the vehicle is equal to or longer than a predetermined distance. Then, in S10, the own vehicle position may be repeatedly specified, and the message may be repeatedly generated based on the specified own vehicle position. With this configuration, it is possible to accurately generate and display a message regarding the monitoring activity while reducing the processing load on the control unit 11.

  The driving support system 1 according to the present embodiment configured as described above outputs the monitoring schedule information determined to be in the “advance situation” from the monitoring schedule information in which the current information such as the own vehicle position and the current time does not match. You can select and display the message. In this driving support system 1, even if the own vehicle position is inconsistent or related to a traffic monitoring activity performed in the past, the monitoring schedule information having a certain relevance is important for the driver related to the scheduled monitoring information. Is treated as important information.

  A description will be given of an example of a prior situation in which the current information such as the position of the host vehicle and the current date and time does not match the monitoring schedule information, but has a predetermined relationship with the corresponding traffic monitoring activity. As the prior situation, as described below, (1) a prior situation where temporal proximity is satisfied, (2) a prior situation where spatial proximity is satisfied, (3) a prior situation having relevance to current information, Etc.

(1) Prior situation where temporal proximity is satisfied.
The “advance situation” that satisfies the temporal proximity includes, for example, whether the current time does not belong to the monitoring period, but the traffic monitoring activity has been performed in the There are situations where monitoring activities are planned. For example, in the sectioned area where the host vehicle is located, regarding the monitoring schedule information regarding the seatbelt enforcement performed in the past, such as last month or last week, the situation represented by the current information is in the `` advance situation '' that satisfies the temporal proximity. It is determined and selected.

The advance situation in which the temporal proximity is satisfied is a situation in which the current time belongs to a predetermined time range that does not include the monitoring period based on the monitoring period in which the traffic monitoring activity is performed.
As shown in FIG. 7, the predetermined time range not including the monitoring period (the range of zero in the circle in the figure) includes a range of the circle 1 in FIG. On the other hand, there is a range indicated by a circle 2 in FIG.

For example, in FIG. 7, the situation where the current time (for example, the inverted triangle box 1 in FIG. 7) belongs to the range of the circle 1 is the “advance situation” for the traffic monitoring activity in the range of the circle 0. In this “advance situation”, the monitoring period during which the traffic monitoring activity is performed is set to the future ahead of the present time in the inverted triangle box 1 in FIG. Therefore, in this “advance situation” in which the current time belongs to the range of the circle 1, the information on the traffic monitoring activity in the range of the circle 0 is the first monitoring schedule information.
On the other hand, for example, in FIG. 7, the situation where the current time (for example, the inverted triangle box 2 in FIG. 7) belongs to the range of the circle 2 is also referred to as the “prior situation” for the traffic monitoring activity in the range of the circle 0. Become. In this “advance situation”, the monitoring period during which the traffic monitoring activity is performed is set in the past before the present in the inverted triangle box 2 in FIG. Therefore, in this “advance situation” in which the current time belongs to the range of the circle 2, the information on the traffic monitoring activity in the range of the circle 0 is the second monitoring schedule information.

  For example, with regard to the monitoring schedule information regarding seatbelt enforcement in the partitioned area where the vehicle is located, not only the monitoring schedule information currently being implemented or scheduled to be implemented, but also the temporal monitoring proximity of the implemented monitoring schedule information is satisfied. Can be treated as being in a “pre-situation”. For example, "The seat belt enforcement was performed in the department of XX on the afternoon of xx month x day. Check whether the seat belt is worn." It is also good to notify the time when it was done. By executing such notification, it is possible to "enhance" awareness of the enforcement on a daily basis.

  Even with the past monitoring schedule information that has been executed, there is a possibility that the same control will be performed again at the same place. Alternatively, information on the next traffic monitoring activity may not have been released as public enforcement information. Therefore, the messages regarding the past traffic monitoring activities as described above are useful references for the driver to perform safe driving. The executed past monitoring schedule information and the like are selected because the current information such as the current time does not match the monitoring schedule information, but satisfies the condition of temporal proximity.

  In addition, in order to select past monitoring schedule information, for example, an embedded database such as SQLite employed in a smartphone (multifunctional mobile phone) or the like is mounted, and the date and time and the coordinate range of the place are set. It is also possible to set the contents of the control and the like in a table. Naturally, it is necessary to keep the monitoring schedule information of the "past" for a certain period of time without deleting it. For example, if a location is set as a search key, it becomes possible to select monitoring schedule information in which the GPS receiver 13 includes the location information in the “location coordinate range” in the table. The search key is not limited to the location, and vehicle information such as time and vehicle speed can be used. For example, if time is set as a search key, it is possible to search for a regulation in a time zone after the current time in a relatively wide range (for example, in prefecture units) including the position of the host vehicle. For example, it is possible to issue a notification such as "XX enforcement was carried out in the future in the area of XX and before OO days. Let's be careful." Not only the past monitoring schedule information (second monitoring schedule information) corresponding to the traffic monitoring activity that has been performed, but also the message regarding future monitoring schedule information (first monitoring schedule information) corresponding to the traffic monitoring activity that is scheduled to be performed. It is also possible to execute the notification by using. With such a notification, the driver or the like can know in advance a schedule for future enforcement several days in advance.

The message may be displayed so that the driver can distinguish whether the message is related to the monitoring schedule information of the past traffic monitoring activity or the monitoring schedule information of the future traffic monitoring activity. For example, if the display color or the background color of the message is changed, it becomes easier for the driver to distinguish it.
The predetermined time range can be set differently for each type of traffic monitoring activity. For example, a longer time range can be set for traffic monitoring activities with high importance such as speed control, while a shorter time range can be set for traffic monitoring activities with low importance such as traffic campaigns.

(2) Prior situation where locational proximity is satisfied.
As the `` prior situation '' where the local proximity is satisfied, for example, while the division area where the vehicle is located is adjacent to the target division area of the traffic monitoring activity, the current time is included in the monitoring period, Or there is a situation just before. For example, with respect to the monitoring schedule information on the seatbelt enforcement that is being performed in the other partitioned area adjacent to the partitioned area where the vehicle is located, the situation represented by the current information is in the “prior situation” that satisfies the spatial proximity. Is determined. It is preferable that the message based on the scheduled monitoring information of the seat belt control be displayed so as to be able to specify that the traffic monitoring activity is being carried out in the adjacent partitioned area. For example, the monitoring schedule information that matches the current information may be obtained by changing the display color of the message or changing the background color.

  The prior situation in which the locational proximity is satisfied is that the current vehicle position, which is one of the current information, does not match the monitoring point or the monitoring area, but a predetermined positional range with respect to the monitoring point or the monitoring area. This is a situation where the condition of spatial proximity of being within is satisfied. For example, instead of the section area including the monitoring point or the monitoring area (the area with a circle in FIG. 8), another section area adjacent to the section area (the area with circles 1 to 6 in FIG. 8). May be set as the predetermined positional range. In FIG. 8, each region is schematically illustrated as a regular hexagon, but, of course, the shape of each region varies from region to region.

  For example, the host vehicle is located outside the section area related to the monitoring schedule information, but is within a predetermined (distance) range within which the vehicle can enter the section area within several hours, and the traveling direction is extended. When the line intersects with the defined area, the monitoring schedule information related to the defined area may be determined to be in the “advance situation”. In this case, before entering the section area related to the monitoring schedule information, the driver can be made to recognize in advance the enforcement schedule related to the monitoring schedule information. For example, if the traffic monitoring activity is a pause control, the current information is acquired that the vehicle has stopped at any intersection in another parcel area where entry into the parcel area where the control is to be performed is expected. At the notification timing, the notification information regarding the stop control is notified in advance. By associating the situation of stopping at the intersection with the fact that the traffic monitoring activity is a patrol, it is possible to notify the driver in advance of the enforcement of the patrol, so that attention should be paid when passing through the intersection. Impress the driver.

For example, a route that passes through a monitoring point or a route that partially belongs to the monitoring area may be set as a predetermined positional range that satisfies the spatial proximity. Of course, in order to set such a positional range, it is necessary to store, for example, route information indicating a road in the first DB.
For example, in addition to a route passing through a monitoring point or a route that partially belongs to the monitoring area, another route connected to the route may be set as the predetermined positional range. Of course, in this case, it is necessary to store link information indicating the connection relationship between different routes in the first DB.

  For example, among the routes to the destination, a route that passes through the monitoring point or a route that partially belongs to the monitoring area may be set as the predetermined positional range. In order to set such a positional range, for example, it is necessary to provide a navigation function for calculating a route to a destination or to fetch route guidance information as a route calculation result from a separate navigation device. . If this route guidance information is used, it is possible to determine that the monitoring schedule information on the traffic monitoring activity in which the monitoring point is located in the divisional area to which the route to the destination belongs is in the “advance situation”. Further, link information indicating a road connection relationship may be stored in the first DB. If the link information is used, it is connected to the route on which the own vehicle is traveling, and it is possible to select another route from which the own vehicle may enter. It is possible to determine that the monitoring schedule information on the traffic monitoring activity in which the monitoring point is located in the divisional area to which the selected other route belongs is in the “advance situation”.

(3) Prior situation related to current information.
As a prior situation of the traffic monitoring activity, a situation having a predetermined relationship with the current information may be set. For example, a situation where the vehicle speed (current information) is high may be determined as a prior situation for a traffic monitoring activity such as speed control. For example, if the notification information based on the scheduled monitoring information of the past speed control by the mobile orvis or the like is notified, the driver can be made aware of the speed limit, and the driver can be encouraged to drive safely according to the speed limit. In this case, for example, even if (1) temporal proximity or (2) locational proximity is not satisfied, it may be determined to be a prior situation and the notification may be executed. It motivates the driver to pay attention to excessive speed.
For example, a situation in which a seat belt is not worn may be determined to be a prior situation for a traffic monitoring activity such as an inspection. If the notification information based on the monitoring schedule information such as the past traffic safety week and the check is notified, the driver can be encouraged to wear the seat belt.

  As the current information (driving information) representing the situation around the vehicle, information such as whether the vehicle is traveling ahead, there is a vehicle approaching from behind, or there is a vehicle running alongside, etc. There are various kinds of information such as information such as red, a pedestrian crossing ahead, a pedestrian in front, and information such as darkness in the evening and raining in the evening. These pieces of current information can be acquired by, for example, detection sensors such as a millimeter wave radar, a laser radar, an ultrasonic sonar, an imaging camera, a raindrop sensor, an illuminance sensor, and an infrared sensor.

  For example, in a situation where the vehicle is traveling ahead, it is also possible to execute a notification assuming that the vehicle is in a prior situation of traffic information, for example, an accident-prone area, to prompt the driver's attention. It is possible to prevent a rear-end collision or the like from occurring. For example, if a situation is detected in which a pedestrian is approaching a walking intersection or a situation in which the driver's line of sight is not heading forward when approaching an intersection, information on past pause enforcement is reported. Good to do. Attention to pedestrians, attention to intersections, etc. can be aroused, and traffic safety can be improved.

  It should be noted that the “advance situation” based on the local proximity or the temporal proximity may be notified, for example, when one of the proximity is satisfied. At this time, if the amount of information to be notified is excessive, it is in a situation where the spatial proximity or the temporal proximity is satisfied, and is in a prior situation having relevance to the current information. The notification may be executed at a certain time. For example, an “advance situation” may be set based on a combination of locational proximity and temporal proximity. For example, neither the own vehicle position nor the current time conforms to the monitoring schedule information, but the monitoring schedule information that satisfies the local proximity condition and the temporal proximity condition is selected. For example, in a section area next to the section area in which the host vehicle is located, it is possible to select monitoring schedule information related to seatbelt enforcement performed in the past, and display a corresponding message.

  The following timing may be set as the notification timing for displaying the message as the notification information. For example, if there is monitoring schedule information related to seat belt control in a partitioned area where the vehicle is located or an adjacent partitioned area, the vehicle ignition is switched on and the time point at which power supply to the driving support system 1 is started is notified. As the timing, notification information regarding seat belt control may be notified.

  It is also possible to acquire a vehicle signal (vehicle information) representing the seat belt wearing as current information. There is a difference in the necessity of performing notification regarding seat belt control between the case where the seat belt is already worn and the case where the seat belt is not worn. In the case of non-attachment, for example, a chime sound is output at the time of notification, and it is possible to indicate that the information is important, to notify the information, or to repeatedly notify. On the other hand, when it is already mounted, it may be simply notified as general information, or the notification may be stopped.

When the vehicle speed (current information) exceeds the speed limit while traveling on a general road, the vehicle speed exceeds the speed limit if there is monitoring schedule information on speed control in the partitioned area where the vehicle is located or the adjacent partitioned area. The time point may be used as the notification timing to notify the notification information about the speed control.
If there is monitoring schedule information related to a traffic safety campaign when approaching an intersection while traveling on a general road, it is also possible to notify the traffic safety notification information using the approach to the intersection as the notification timing. The approach to the intersection can be detected based on the map information or the road route information stored in the first DB and the position information acquired by the GPS receiving unit 13.

  According to the driving support system 1 of this example, it is possible to notify information on the traffic monitoring activity “in advance” in a situation where the traffic monitoring activity is not the subject of the public control information. When the information is announced `` in advance '', there are cases where the public control information is future information and the current information is out of its target range but is notified as a preliminary stage of traffic monitoring activities, There is a case in which the past (implemented) public control information is notified to notify the driver himself for foreseeing (consciousness).

  As described above, in the driving support system 1 of the present example, the monitoring schedule information whose location does not match and the past monitoring schedule information are also notified in a situation having a predetermined relationship with the current situation. For example, if the notification based on the past monitoring schedule information is executed, it is possible to make the driver aware of the need for caution because the control related to the current situation has been made in the past. Even in the case of the publicly-announced traffic control information on the traffic monitoring activity that has already been performed, the driver can use the ex-post information to make a prediction or estimation of the traffic monitoring activity in advance.

  According to the driving support system 1, not only the traffic monitoring activity actually performed at the present time but also the traffic monitoring activity performed in the future and the information on the traffic monitoring activity performed in the past are provided to the driver. can do. In addition, the driver can be provided with information on not only traffic monitoring activities whose location matches the vehicle position but also traffic monitoring activities whose location does not match but are relevant to the current situation. Drivers may not only carry out surveillance activities near their own vehicles, but also traffic monitoring activities that may be carried out in the future, past traffic surveillance activities, Traffic surveillance activities can be grasped, and further attention can be paid to driving in places where traffic accidents are likely to occur.

  In addition, the driving support system 1 of this example can specify the division area where the vehicle is located in units of municipalities. According to the driving support system 1, the position of the host vehicle can be specified in more detail on a municipal or municipal basis regardless of whether the vehicle is on a highway or a general road, and information useful to the driver can be presented.

  The driving support system 1 can specify a partitioned area covering the area where the monitoring activity is performed, based on the third DB stored in the SD card 171. The third DB stores monitoring schedule information associated with one or more pieces of area information. The area information of the partitioned area where the vehicle is located and the area information of the partitioned area included in the monitoring schedule information are both determined in units of municipalities. The driving support system 1 can uniformly specify whether or not the monitoring activity is being performed in the partitioned area where the vehicle is located based on the third DB. According to the driving support system 1, it is possible to easily and reliably identify and notify the driver of a message of information related to a monitoring activity performed near a place where the host vehicle is actually located.

  Only a message (notification information) necessary for the driver is displayed on the display unit 14. Therefore, it is possible to prevent the driver from overlooking necessary information by displaying a large number of unnecessary messages. The driving support system 1 allows the vehicle to enter the municipalities including at least the announced area even when "~ jurisdiction", "~ direction", "~ line along" is announced as the area where the monitoring activity is performed. Can be specified. This is because the area information of the divided area where the traffic monitoring activity is performed is associated with the monitoring schedule information stored in the third DB in units of municipalities. Therefore, the driving support system 1 can generate a message suitable for the position of the vehicle based on the monitoring schedule information, and can notify the driver. The driver can easily grasp the information on the monitoring activity performed near the position of the host vehicle.

  Note that the present invention is not limited to the above-described embodiment, and various modifications are possible. For example, the driving support system 1 may be configured not to include the wireless receiving unit 12. The driving support system 1 may grasp the distance between the notification target and the vehicle based on the voltage level of the RSSI output from the externally mounted wireless receiving unit. Further, the driving support system 1 may have a configuration without the GPS receiving unit 13. The driving support system 1 may grasp the vehicle position based on the position information output from a GPS receiving unit attached to the outside. In addition, the driving support system 1 may be configured not to include the display unit 14 and the speaker 15. The driving support system 1 may display a desired image on an external display by controlling the external display. The external display may be, for example, a display of a car navigation system attached to a vehicle. The driving support system 1 may output a desired sound from the external speaker by controlling the external speaker. The external speaker may be, for example, a speaker attached to a vehicle.

  For example, a situation where the vehicle speed specified as the current information is high may be determined as a prior situation for a traffic monitoring activity such as speed control. For example, if the notification information based on the monitoring schedule information of the past speed control by the mobile orvis or the like is notified, the driver can be conscious of the speed limit, and the effect of being able to promote safe driving in compliance with the speed limit is produced. . For example, the current information that the seat belt is not worn may be determined to be a prior situation for a traffic monitoring activity such as a check. If the notification information based on the monitoring schedule information such as the past traffic safety week and the check is notified, the driver can be encouraged to wear the seat belt.

  As a prior situation having a relationship with the current information, for example, in the case of seat belt enforcement, the situation at the time when the current information specifying the engine start is acquired, or the time from the start of the engine to the start of operation. There is a situation or the like when an assumed predetermined time has elapsed. For example, when the traffic monitoring activity is drinking control, the situation where the current information indicating the travel in the direction away from the downtown area is acquired together with the current time after 6:00 pm may be the prior situation. For example, if the traffic monitoring activity is an intersection-related regulation, the situation where the current information indicating that the vehicle has stopped at the intersection may be the prior situation.

  The content of the message, which is information to be notified to the driver, is not limited to the public control information published by each prefectural police station. For example, the information (regulatory contents, route, address, month Day and time).

The operator may create the third DB based on the published disclosure control information as follows. When the disclosed disclosure control information satisfies the following conditions (1) and (3), or satisfies the following conditions (2) and (3), the operator is to monitor various items associated with each other. Create information.
(1) When the municipalities where monitoring activities are carried out are published as publicly available information.
(2) When the jurisdiction or region where monitoring activities are carried out is disclosed as public regulatory information.
(3) When the date and time when the monitoring activity is to be carried out are disclosed as public regulatory information.

  In the above description, the operator creates the third DB including the monitoring schedule information based on the published disclosure control information. Of course, the invention is not limited to this. A server (computer device) including a collection unit that collects traffic control information and generates monitoring schedule information may automatically perform the process of creating the third DB including the monitoring schedule information. Specifically, it is preferable to carry out as follows. Furthermore, if the in-vehicle device has a wireless communication function, the monitoring schedule information may be downloaded from this server, or the third DB itself may be downloaded.

  The public control information released via the HP of each prefectural police station is acquired by a server connected to the Internet. For example, the server periodically (for example, once a day) checks the HP of each prefectural police station of the URL stored in advance, and determines whether or not the public control information has been updated. When the public control information has been updated, the public control information of the page of the URL is acquired. From the plurality of public control information in the obtained public control information page, the monitoring schedule information and each information (“prefecture”, “start date”, “start time”, “end date”, "End time" and "jurisdiction"). A plurality of pieces of information in the page are extracted, and information as illustrated in FIG. 2 is created in association with the monitoring schedule information. The created information is stored in the storage unit of the server.

  The areas where monitoring activities are announced by the public control information are, for example, "prefectures," "jurisdictions," "routes," etc. In many cases, the unit differs from the unit of the divided area. In such a case, the server specifies an “implementation place” to be associated with the monitoring schedule information as follows.

  The server is used as an area where traffic monitoring activities are performed (prefectures, jurisdictions, routes, etc .; hereinafter, referred to as "public areas"), which are published as public enforcement information for each prefectural police, and between the prefectural police. A correspondence table in which area information specified in units of municipalities as common units is associated with each other is stored in the storage unit in advance. The area information associated with the open area includes at least the area information of the divided area where the traffic monitoring activity is actually performed. For example, a plurality of area information may be associated with one open area. When the server obtains the disclosure control information from the HP of each prefectural police station, the server extracts the disclosure area included in the obtained disclosure control information. Then, referring to the correspondence table stored in the storage unit, the area information corresponding to the extracted open area is specified. The specified area information is associated with the monitoring schedule information as an “implementation place”. Further, "prefecture", "start date", "start time", "end date", "end time", and "jurisdiction" extracted from the disclosure control information are associated with the monitoring schedule information. Then, monitoring schedule information associated with various types of information is stored in the storage unit. Note that the method for specifying the divided area is not limited to the above-described method.

  The message displayed in the second sub-display area 23 includes information other than the scheduled monitoring information, for example, information on events such as enhancement months, seasonal feelings, customs, etc., road regulation information (construction regulations, traffic regulations due to disasters), and the like. May be. For example, by displaying road regulation information, the driver can avoid a restricted route beforehand. Information other than the traffic monitoring activity is stored in the SD card 171 together with the third DB, and the information may be read and stored in a message.

  The title and the monitoring schedule information stored in each phase in the message displayed in the second sub-display area 23 have the type of the monitoring activity and the monitoring activity so that they can be easily understood even when they are continuously arranged and scrolled. It is also possible to sort by background color or color letter for each period during which the monitoring is performed and for each region where the monitoring activity is performed, or to add an icon at the top. As shown in FIG. 4, the total number of titles may be added to the title so that the entire message can be grasped, and the number of pages may be added to each piece of monitoring schedule information.

  The driving support system 1 may also generate a message to be displayed in the second sub-display area 23 in the following cases. It is assumed that monitoring schedule information that is not associated with “execution location” is stored in the third DB. From such monitoring schedule information, all the monitoring schedule information in which the same prefecture as the prefecture where the vehicle is located is associated with “prefecture” is extracted. The period during which the traffic monitoring activity is performed is specified based on the “start date”, “start time”, “end date”, and “end time” (see FIG. 2) associated with the extracted monitoring schedule information. Within the specified period, the monitoring schedule information including the current date and time specified in S106 is selected, and a message is created based on the selected monitoring schedule information. The driving support system 1 selects monitoring schedule information related to monitoring activities performed in the prefecture where the vehicle is located, and generates a message.
