Description

  The present invention relates to a driving support system that supports a driver's driving by providing the driver with traffic monitoring information suitable for the current position of the vehicle.

  Driving assistance that stores position information of a target to be detected and issues a warning to the driver when the position of the vehicle detected by GPS and the stored position of the target are in a predetermined relationship The system is known. Examples of the target include a device for measuring vehicle speed and a control / inspection area. For example, in Patent Document 1, when the distance between a target and a vehicle reaches a set distance, information for specifying the target or the like can be displayed on a display, or an alarm can be output by voice. A support system has been proposed. The target is often installed in a dangerous place where a traffic accident is likely to occur. Accordingly, the driving support system can prompt the driver to drive safely in a place where a traffic accident is likely to occur by notifying the driver of the approach to the target. As described above, informing the driver of the approach to the target object contributes to the driver's safe driving.

  Surveillance activities to promote safe driving occur irregularly at unspecified locations. One example of such monitoring activity is police enforcement or inspection. Surveillance activities are often performed in dangerous places where traffic accidents are likely to occur, such as sites where past traffic accidents have occurred. Therefore, it is possible to memorize a place where a monitoring activity has been performed in the past as a target, and to provide information on the monitoring activity to the driver when a vehicle approaches that location. The driver can be encouraged to drive safely in an easy place. Hereinafter, information related to monitoring activities for promoting safe driving is also referred to as traffic monitoring information.

JP 2011-22161 A

  However, since the place memorized as the target is the place where the monitoring activity was performed in the past, there is a high possibility that the monitoring activity will be carried out in the future, but when the driver passes the place, the monitoring activity Is not necessarily implemented. Therefore, in addition to these functions, there is a device for notifying public control information published by each prefectural police. Such public control information is often published by designating at least one of a predetermined region, time zone, and content of control. For example, prefectures, municipalities, police jurisdictions, routes, etc. are designated and announced as predetermined areas where surveillance activities are performed. If here the conventional driving support systems, public enforcement information because those prefectural police announced, stores the traffic enforcement information for each prefecture, to notify traffic enforcement information in advance what prefecture When the device is turned on by starting the engine or the like, the public control information of the set prefecture is notified. Usually, the prefecture where the home is located is registered in advance as setting information indicating which prefecture's traffic control information is to be notified. Therefore, since the conventional driving support system is notified of the public control information of the prefecture range set as the position of the home, even if it is actually a place far away from the home, it includes the position of the home Public control information for the entire prefecture will be notified. Even if the predetermined area where the monitoring activity is performed is a place far away from the home, all the public control information is notified if it is in the same prefecture as the home. For this reason, there is a problem for the driver that information on a distant place that has no relation is notified. Moreover, there is a possibility that public control information near the home is missed in such a large amount of information, and the public control information near the home that is really necessary may be missed. This is because the range of prefectures includes a range having a considerable distance from the home (usually a range greatly exceeding the range moved by commuting or the like).

  In addition, in the conventional driving support system, since each prefecture announces public control information, the prefectural border is specified on the expressway route based on the simple idea that information should be broadcast for each prefecture. For example, when the location information is stored as a target and the location information is approached or passed, the public control information of the prefecture is reported. In this configuration, when the vehicle is traveling on a highway, the position of the prefectural border can be detected. Therefore, it is detected that the vehicle is approaching the prefecture where the monitoring activity is performed, and the driver Can be notified of traffic monitoring information of the prefecture. However, when the vehicle is traveling on a general road, there is a problem that the conventional driving support system cannot notify the traffic monitoring information driver. Also, even if you are driving on an expressway and public control information for the prefecture is reported, the place where the monitoring activities are actually performed may be far away from the prefectural border . Therefore, there is a problem for the driver that traffic control information of a remote place that is not relevant is reported. In addition, the public control information near the prefectural border is covered by such a lot of information, and there is a possibility that the public control information nearby that is really necessary may be missed.

  An object of the present invention is to provide a driving support system that can provide a driver with traffic monitoring information suitable for the current position of a vehicle, instead of simply reporting traffic monitoring information in units of prefectures as in the past. It is to provide.

  The driving support system according to the first aspect of the present invention includes region identification information for identifying a partition region, which is a region formed by partitioning land, and a region position for specifying the position of the partition region. Information on the traffic monitoring activity, first acquisition means for acquiring the area identification information of the section area including the position of the vehicle based on the stored contents of the first storage means stored in association with the information; Based on the storage content of the second storage means, which is certain traffic monitoring information, in which traffic monitoring information in which the area identification information of the section area including the area where the monitoring activity is performed is associated is stored. Second acquisition means for acquiring the traffic monitoring information associated with the area identification information acquired by the first acquisition means, and display based on the traffic monitoring information acquired by the second acquisition means And a first control means for performing control for displaying on the display means the distribution.

  According to the first aspect, the driving support system can specify the partitioned area where the vehicle is located based on the stored contents stored in the first storage unit. In addition, the driving support system can specify a partitioned area including a place where the monitoring activity is performed based on the contents stored in the second storage unit. For example, the driving support system identifies the partition area where the vehicle is located by referring to the storage content stored in the first storage means, and monitors the activity by referring to the storage content stored in the second storage means. The partition area including the place where is implemented is specified. With these, the driving support system can specify whether or not the monitoring activity is being performed in the partitioned area where the vehicle is located. Therefore, the driving support system can create display information based on the traffic monitoring information corresponding to the section area where the vehicle is located, and can notify the driver. For this reason, the driver does not need to set the prefecture to which the home belongs in the driving support system as in the prior art. Further, the driving support system can notify the traffic monitoring information corresponding to the section area where the vehicle is located even when the vehicle is traveling on a general road that is not an expressway.

  For example, even when a predetermined area is designated and announced as a place where the monitoring activity is performed, the driving support system can specify whether or not the vehicle has entered a partition area including at least the predetermined area. it can. Examples of the predetermined area include prefectures, municipalities, police jurisdiction units, routes, and the like. For this reason, the driving support system can acquire traffic monitoring information suitable for the position of the vehicle, create display information, and provide it to the driver. The driver can easily grasp the monitoring activities performed near the current position of the vehicle. Surveillance activities are often carried out in places where traffic accidents are likely to occur. Therefore, the driver can drive while paying attention to safety by recognizing that the current position is a dangerous place where a traffic accident is likely to occur. In this way, the driving support system can prevent a traffic accident from occurring.

  The second storage means stores traffic monitoring information including the area where the monitoring activity is performed. Therefore, the driving support system can easily specify the traffic monitoring information related to the monitoring activity actually performed near the vehicle from the position of the vehicle. The driving support system can acquire information related to monitoring activities performed near the vehicle in a short time and accurately, and provide the information to the driver. In particular, the traffic monitoring information stored in the second storage means includes information on the implementation area of the monitoring activity announced by each prefectural police, and the traffic monitoring information acquired by the second acquisition means is determined by each prefectural police. Information on the area where the monitoring activity is announced is included, and information regarding the area where the monitoring activity is performed may be displayed as display information based on the traffic monitoring information. In this way, the driver can directly know the implementation area of the monitoring activity announced by each prefectural police in the zone where the monitoring activity is performed.

  Moreover, 1st aspect WHEREIN: The area | region specified by the said division area may be smaller than a prefecture. As a result, the driving support system can set a region of a unit smaller than that of the prefecture, for example, a municipality as a partitioned region. As a result, the driving support system can specify the position of the vehicle in units of municipalities, and can acquire traffic monitoring information related to the monitoring activities performed near the vehicle. Thus, since the driving assistance system can specify the position of the vehicle in detail, it is possible to notify information related to the monitoring activity being performed closer to the vehicle.

  Further, in the first aspect, the partition area identified by the area identification information associated with the traffic monitoring information is designated when the base information that is information on which the traffic monitoring information is based is announced. It may be different from the area where the activity is conducted. As a result, the driving support system refers to the traffic monitoring information associated with the common area identification information regardless of the designated method (prefecture, city, jurisdiction, route, etc.) can do. As a result, the driving support system can reliably identify the monitoring activity being performed in the vicinity of the vehicle.

  Moreover, in the first aspect, the basic information is announced by a plurality of prefecture polices, and the unit of the monitoring area to be designated when the basic information is announced is the basic information for each basic information. A plurality of traffic monitoring information created based on a plurality of the basic information published by a plurality of prefecture polices, Area identification information may be associated. As a result, the driving support system can be used in the vicinity of the vehicle based on a common area, even if there are a wide variety of methods for identifying the areas where monitoring activities are announced (prefectures, municipalities, jurisdictions, routes, etc.). It is possible to identify the monitoring activities being carried out. Therefore, the driving support system can easily identify the monitoring activity being performed near the vehicle.

  Further, in the first aspect, the vehicle includes first specifying means for specifying time, wherein the traffic monitoring information is associated with a period during which the monitoring activity is performed and the area identification information, and the second acquisition means Is associated with the region identification information acquired by the first acquisition means, and the time period in which the relationship with the time specified by the first specification means satisfies a predetermined relationship. Traffic monitoring information may be acquired. As a result, the driving support system can provide the driver with information regarding the monitoring activities actually performed at the present time and the monitoring activities to be performed soon. Since the driving support system can immediately recognize and provide information more useful to the driver, the driver can more safely drive in a place where a traffic accident is likely to occur.

  In the first aspect, the display information may be text information, and the first control unit may perform control for scrolling display of the display information.

  When the driver visually recognizes the display means while driving, the line of sight is repeatedly directed to the display means at short intervals. The driver cannot visually recognize the display means for a long time during driving. For this reason, when the amount of information displayed on the display means is large, if information is displayed on the display means at a time, the driver may not be able to recognize the information correctly. On the other hand, the driving support system can reduce the data amount of information displayed at a time on the display unit by scrolling the text information. Thus, the driver can accurately recognize the displayed information even when the display means is viewed repeatedly at short intervals.

  In the first aspect, when the display information is all displayed by scroll display, the first control means may perform control for repeatedly displaying the display information from the beginning. Thereby, the scroll display of the display information is repeatedly executed a plurality of times. Thereby, the driver can recognize the information displayed again even if the information regarding the monitoring activity is once missed.

  Further, in the first aspect, the traffic monitoring information includes a category, and the first control unit acquires the plurality of traffic monitoring information acquired when the plurality of traffic monitoring information is acquired by the second acquisition unit. Control for collectively displaying the display information based on the category may be performed. As a result, when there are a plurality of pieces of information related to the monitoring activity, each piece of information is classified and displayed for each category. The categories include regulatory information and inspections. The driver can easily recognize the information related to the monitoring activity for each category.

  In the first aspect, the vehicle may further include second specifying means for specifying the traveling speed of the vehicle, and the first control means may display the display information according to the traveling speed of the vehicle specified by the second specifying means. You may perform control for displaying so that the display speed in the case of scrolling may change.

  For example, when the traveling speed of the vehicle is high, it is assumed that the driver cannot direct his / her line of sight to the display means for a long time. In such a case, the driving support system slows the display speed when scroll display is performed. Accordingly, the driver can surely recognize the displayed information within a short time. On the other hand, for example, when the traveling speed of the vehicle is low, it is assumed that the driver can direct his / her line of sight to the display unit for a long time. In such a case, the driving support system increases the display speed when scroll display is performed. As a result, the driver can accurately recognize a large amount of information.

  In the first aspect, the first control means displays information for specifying the partition area identified by the area identification information acquired by the first acquisition means simultaneously with the display information. Control may be performed. As a result, the driver can recognize the current position of the vehicle simultaneously with the information related to the monitoring activity. For example, when the monitoring activity is performed over a wide area, the driver can confirm to which part of the region where the current position of the vehicle the monitoring activity belongs. As a result, the driver can grasp a place where special attention should be paid to safe driving and can perform driving.

  In the first aspect, the position of the vehicle is changed, and the region identification information acquired by the first acquisition unit is updated as the position of the vehicle is changed. When the area identification information acquired by the first acquisition means is updated, a new control means is provided for performing control to output sound when new traffic monitoring information is acquired. Also good. Thus, the driver can surely recognize the updated display information by visually recognizing the display means when notification is given by sound. In this way, the driving support system can prevent the driver from overlooking information related to the monitoring activity.

  For example, in the driving support system, the position of the vehicle may be specified at a predetermined time interval (for example, every 1 second), or the position of the vehicle may be specified when the moving distance of the vehicle becomes a predetermined distance or more. . And based on the position of the vehicle repeatedly specified in this way, the traffic monitoring information corresponding to the partitioned area and the partitioned area may be repeatedly specified. Then, control may be performed so that sound is output when the specified traffic monitoring information becomes new.

  Moreover, the 1st aspect WHEREIN: You may provide the 3rd control means which performs the control for displaying the surrounding map containing the position of the said vehicle simultaneously with the said traffic monitoring information. Thus, the driver can recognize geographical information around the current position of the vehicle. For example, by recognizing the surrounding road environment, the driver can reduce the traveling speed in advance or pay sufficient attention to the surrounding environment in advance. As described above, the driving support system can provide the driver with information necessary for the safe driving of the driver together with the traffic monitoring information.

  In the first aspect, the area where the monitoring activity is performed may span a plurality of the partitioned areas, and the traffic monitoring information may be associated with a plurality of the area identification information. As a result, the driving support system can accurately specify information related to the monitoring activity performed near the vehicle even when the monitoring activity is performed over a wide area.

  For example, it is assumed that a municipality is stored in the first storage unit as a partitioned area. Suppose that "~ inside the jurisdiction", "~ direction", "~ along the line", etc. were announced as areas where surveillance activities are carried out. As described above, even if the unit of the announced region is larger than the unit of the divided region, the divided region of a unit smaller than the unit of the published region can be uniformly included in the traffic monitoring information. As a result, the driving support system can accurately and easily specify information related to the monitoring activity in the section area where the vehicle is located and notify the driver. In addition, the driving support system can accurately identify and provide information to the driver regarding the monitoring activity performed near the vehicle even when the area where the monitoring activity is performed is not specifically disclosed.

  In the first aspect, the display information may include at least one of a type of the monitoring activity, a period during which the monitoring activity is performed, and a region where the monitoring activity is performed. As a result, the driver can recognize the priority items of the control as, for example, the type of the monitoring activity. The priority items for enforcement include overspeeding, overloading, seat belts, drunk driving, and signal ignorance. For example, the driver can recognize the police jurisdiction, the route, the municipality, etc. as the area where the monitoring activity is performed. By these, the driver can grasp the information related to the monitoring activities in detail and perform the driving considering the traffic safety by paying particular attention to these points.

  In the first aspect, the first control means may perform control for displaying the type, the period, and the area in different colors. As a result, the driver can easily distinguish and recognize the type, period, and area of the monitoring activity.

  An information generation method according to the second aspect of the present invention is an information generation method for generating information stored in the second storage means that is referred to by the driving support system according to the first aspect. Area identification information for identifying a plurality of the divided areas including at least the area where the corresponding monitoring activity is performed is extracted, and the traffic monitoring information associated with the extracted area identification information is extracted as the second It memorize | stores in a memory | storage means, It is characterized by the above-mentioned. According to the second aspect, traffic monitoring information in which region identification information that is a common category is associated with each other even if the regional category of the information related to the monitoring activity that is disclosed is different for each information that is disclosed. Can be stored in the second storage means.

  Assume that region identification information for identifying a publicly disclosed region is associated with traffic monitoring information. In this case, it is more preferable because the area where the monitoring activity is performed can be accurately specified. However, the category of the area to be announced (such as “~ inside the jurisdiction”, “to the direction”, “to the line along the line”, etc.) may differ depending on the information to be announced. When the categories are different, in order to specify the information related to the monitoring activity performed at the current position of the vehicle, the category of the partition area identified by the area identification information stored in the first storage means is also changed. Needed and annoying. In addition, depending on the category, there may be a case where the region where the monitoring activity is performed cannot be specifically identified. On the other hand, according to the second aspect, since the category of the area identification information associated with the traffic monitoring information is unified, even if the published area category is changed, the first storage means There is no need to change the stored area identification information.

  In the second aspect, in the extraction, the area where the monitoring activity corresponding to the published information is performed and the area identification information of the plurality of partition areas including at least the area are stored in association with each other. By referring to the third storage means, region identification information for identifying the plurality of partitioned regions may be extracted. Thereby, the area identification information corresponding to the published traffic monitoring information can be easily identified and associated with the traffic monitoring information.

  The driving support program according to the third aspect of the present invention causes a computer to execute each processing means of the driving support system according to the first aspect of the present invention. Thereby, the same effect as the first aspect can be obtained.

  A generation program according to a fourth aspect of the present invention is a generation program for generating information stored in the second storage means that is referred to by the driving support system according to the first aspect of the present invention. Region identification information for identifying the plurality of partition regions including at least the region where the monitoring activity corresponding to the information is performed is extracted, and the traffic monitoring information associated with the extracted region identification information is extracted. Storage in the second storage means can be executed by a computer.

  In addition, the system provided with the driving assistance system which concerns on a 1st aspect, and the information generation apparatus which produces | generates the information memorize | stored in said 2nd memory | storage means may be sufficient as this invention. The information generating apparatus includes: an extraction unit that extracts region identification information for identifying a plurality of partition regions including at least a region where the monitoring activity corresponding to the published information is performed; and the extraction unit extracts the region identification information You may provide the memory | storage control means which memorize | stores the said traffic monitoring information matched with several said area | region identification information in said 2nd memory | storage means. Further, the extraction means stores an area where the monitoring activity corresponding to the published information is performed and area identification information for identifying the plurality of partition areas including at least the area. The plurality of region identification information may be extracted by referring to the third storage unit.

Specific examples of the radio signal received by the radio receiver 12 include a radar signal output from the speed measuring device, a radio signal transmitted from the enforcement communication radio, and transmitted / received between each police headquarters and the mobile station. Examples thereof include a digital radio signal, a radio signal used in a police-dedicated automobile cellular phone system, and a radio signal transmitted from an emergency vehicle. The radio reception unit 12 may include a plurality of radio modules in order to distinguish and receive radio signals having a plurality of frequencies. When receiving the radio signal, the radio reception unit 12 detects the signal level of the received radio signal and outputs it as a received signal strength indication (RSSI). The control unit 11 recognizes the signal level of the received radio signal based on the RSSI voltage level output from the radio reception unit 12, and predicts the distance between the object that transmitted the radio signal and the host vehicle. can do.

  The GPS receiving unit 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 host vehicle based on the received radio signal. The position information is the latitude and longitude of the vehicle position. The control unit 11 identifies the vehicle position based on the position information output from the GPS receiving unit 13.

  The display unit 14 is, for example, a liquid crystal display, an EL display, or the like. The control unit 11 can control the display unit 14 to display a desired image. The control unit 11 can control the speaker 15 to output a desired sound. 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 types of information. The storage unit 16 is, for example, an EEPROM, a flash memory, a hard disk drive, or the like. The storage unit 16 stores map data, image data displayed on the display unit 14, sound data output from the speaker 15, and various databases. Various databases include at least a first DB and a second DB.

  The first DB stores polygon data that can identify administrative divisions based on position information. Administrative divisions are established for each municipality. Hereinafter, an area represented by an administrative division is also referred to as a division area. The polygon data is associated with area identification information for identifying the partitioned area. The control unit 11 refers to the first DB based on the position information output from the GPS receiving unit 13, and thus area identification information for identifying the division area where the host vehicle is located is smaller than the prefecture unit. It can be specified on a municipal basis. In addition, the area | region represented by the division area in this invention is not limited to a municipality, You may represent another area | region.

  In the second DB, information related to the target to be notified to the driver is stored. Examples of the target include a speed measurement device (including a speed measurement device that emits a radar wave (microwave) like a radar and a speed measurement device that does not emit a radar wave like a loop coil), a speed limit switching point, Enforcement area, inspection area, banned monitoring area, N system, traffic monitoring system, intersection monitoring point, signal ignorance suppression system, police station, accident-prone area, on-vehicle frequent occurrence area, sudden / continuous curve (highway), branch / Junction point (highway), ETC lane advance guidance (highway), service area (highway), parking area (highway), parking area (highway), highway oasis (highway), smart interchange (highway) , Gas station (highway) in PA / SA, tunnel (highway), highway radio reception area (highway) , Border announcement, the way of the station, there is a view point parking and the like. Hereinafter, the target notified to the driver is also referred to as a notification target. In the second DB, information indicating the type of the notification object, latitude and longitude information indicating the position of the notification object, schematic diagram or photo data displayed on the display unit 14, and sound output from the speaker 15 Data is stored in association with each other. The control unit 11 can specify a notification object 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 unit 16 when the driving support system 1 is shipped. The first DB and the second DB can be updated by a known method. For example, the first DB and the second DB may be stored in the SD card 171. The first DB and the second DB may be updated by storing the first DB and the second DB read from the SD card 171 via the card reader 17 in the storage unit 16. For example, the driving support system 1 may have an infrared communication function. The first DB and the second DB may be updated by performing infrared communication with an external device to acquire the first DB and the second DB and storing them in the storage unit 16.

  The SD card 171 stores a third DB in which a plurality of traffic monitoring information is stored. The traffic monitoring activity is information relating to the monitoring activity for promoting safe driving. One example of surveillance activities is police enforcement or inspection. Surveillance activities occur irregularly at unspecified locations. The control unit 11 can specify the details of the monitoring activity being performed near the host vehicle by referring to the third DB.

  Details of the third DB will be described with reference to FIG. Of the information stored in the indexes 1 to 15, the information stored in the lower row corresponds to the traffic monitoring information. The traffic monitoring information includes the “prefecture”, “start date”, “start time”, “end date”, “end time” where the monitoring activities are carried out, “the jurisdiction” police station that conducts the monitoring activities, and “implementation” "Location" is associated. For example, the information of index 2 in FIG. 2 ("start date: 20110307" "start time: 12h00m" "end date: 20110307" "end time: 18h00m" "jurisdiction: Iwate Prefectural Police" "location: Kuzumaki-cho: 302" , "Traffic Monitoring Information: [Regulation] Afternoon Iwate Prefectural Police ~") is under the jurisdiction of Iwate Prefectural Police from 12:00 to 18:00 on March 7, 2011 in any area of Kuzumaki-cho. Is meant to be done. Of the “implementation place”, 302 is area identification information for specifying a municipality.

  As traffic monitoring information, text information related to monitoring activities is stored. The text information stored as the traffic monitoring information is used as it is as a message displayed on the display unit 14. The category of the monitoring activity is stored in the portion surrounded by [] in the text information. The text information stored as traffic monitoring information is composed of “what”, “when”, and “where” so that the driver can grasp the contents even while driving (while watching the flicker). Is spelled in a single sentence. The “what” information indicates the contents of the control such as “speed violation”, “drinking”, “pause”, and the like. The “when” information indicates a time zone or date when the monitoring activity is performed. The “where” information indicates, for example, an address or a route on which the monitoring activity is performed.

  The traffic monitoring information is information that has been converted into data based on a predetermined format, which is made public through the homepages (hereinafter referred to as “HP”) of prefectural police nationwide. The control unit 11 displays the message based on the traffic monitoring information in a telop on the display unit 14 at a location and time according to the content. The driver becomes aware of the message displayed in the telop, and thus tries to drive safely. The traffic monitoring information includes the type of monitoring activity (“what”), the period during which the monitoring activity is performed (“when”), and the region where the monitoring activity is performed (“where”). . For this reason, when a message is created based on the traffic monitoring information and notified to the driver, the driver can recognize, for example, the priority items of the control as the type of the monitoring activity. The priority items of the control include, for example, overspeed, overloading, seat belts, drunk driving, signal ignorance, and the like. Further, for example, the driver can recognize the police jurisdiction, the route, the municipality, etc. as the area where the monitoring activity is performed. By these, the driver can grasp the traffic monitoring information in detail and perform the driving considering the traffic safety by paying particular attention to these points. Hereinafter, information related to monitoring activities, which is publicized through the websites of the prefectural police nationwide, is collectively referred to as public control information.

  The information stored in the third DB is created when the operator converts the control information published through the HPs of the prefectural police nationwide into data. As shown in FIG. 2, the implementation date, time zone, location, type, etc. are extracted from the published public control information with the same wording as much as possible, converted into data, and associated with the traffic monitoring information. Since the public control information is published through the homepage of each prefectural police, as shown in FIG. 2, each traffic monitoring information is collected for each prefectural government. In addition, each piece of information is one item for each date, time zone, jurisdiction, municipality, or control type. Since the storage capacity of the SD card 171 is limited, the traffic monitoring information is collected in a short and easy-to-understand manner. In addition, depending on the public control information published, a specific item may not be published among the information stored in the third DB. In such a case, the operator does not convert the information corresponding to the item that has not been publicized into data. For this reason, in such a case, information is not stored in items that have not been publicized.

  The items associated with the traffic monitoring information are not limited to the above. Each item may be collected so that the efficiency when the operator creates information stored in the third DB is improved.

  In the “implementation place” associated with the traffic monitoring information, area identification information for identifying a divided area in units of municipalities is stored. For this reason, for example, when the information published as the place where monitoring activities are carried out, such as “prefectural roads”, spans multiple municipalities, all area identification information for identifying the relevant municipalities is It is said to be “implementation place”. For example, in the information of index 5 in the third DB of FIG. 2, when the monitoring activity is executed on “prefectural road”, the area identification information “302 (Kuzumakicho)” “501 (Kumokucho)” is used as “implementation place”. ”And“ 209 (Ichinoseki City) ”are associated with the traffic monitoring information. Thus, when the monitoring activity is disclosed over a wide area, a plurality of area identification information is associated with the common traffic monitoring information. This clarifies the areas where monitoring activities are carried out.

  As described above, since the polygon data that can specify the area identification information is stored in the first DB in the first DB, the area identification information of the division area where the host vehicle is located is the municipality. Identified in units. The area identification information of the division area where the host vehicle is located and the area identification information associated with the traffic monitoring information as “implementation location” are both the same for each municipality. For this reason, the same area as the area where the host vehicle is located can be searched uniformly from the “place of implementation” in the traffic monitoring information. Traffic monitoring information can be easily identified.

  For example, the area where surveillance activities are carried out is publicly disclosed on a regional basis, such as “~ in the jurisdiction” for A prefectural police, “~ direction” for prefectural police B, “along line” for C prefectural police. Suppose. In this way, the public control information differs in the unit of the area where the monitoring activities are carried out for each prefectural police. Even in such a case, in the public control information announced by all prefectural police, the area identification information for identifying the area of each municipality is associated with the traffic monitoring information, and is used as the “implementation place” uniformly. . A unit differs between the area announced by each prefectural police and the section area corresponding to the traffic monitoring information. As a result, the driving support system 1 can uniformly, accurately, and easily specify the traffic monitoring information related to the monitoring activity performed in the section area where the vehicle is located. Therefore, as described above, even when the area where the monitoring activity is performed is announced in a state where the area cannot be specifically identified, the driving support system 1 accurately specifies information related to the monitoring activity performed near the vehicle. be able to.

  The third DB including the traffic monitoring information created by converting the public control information into data can be downloaded from the dedicated HP on the user side. The downloaded third DB is stored in the SD card 171. When the own vehicle position is specified for the first time on the basis of the position information output from the GPS receiving unit 13 and when there is a change in the partitioned area including the own vehicle position, the control unit 11 The set SD card 171 is accessed. When the partitioned area where the host vehicle is located is determined, traffic monitoring information related to the monitoring activity performed in the nearest area is read from the third DB stored in the SD card 171. Display based on the read traffic monitoring information. The details of the process when a message created based on the traffic monitoring information is displayed on the display unit 14 will be described later.

  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. The display screen 20 is provided with a main display area 21, a first sub display area 22, and a second sub display area 23. The main display area 21 is an area for displaying an image for indicating the positional relationship between the host vehicle and the notification object. The first sub display area 22 is an area for displaying the name of the partition area where the host vehicle is located. The second sub display area 23 is an area for displaying a message regarding the monitoring activity. Hereinafter, the details of each region will be described.

  The main display area 21 will be described. The main display area 21 includes an area 211 for displaying a map image, an area 212 for displaying the type of the notification object and the distance to the notification object, an area 213 for displaying the traveling speed of the vehicle, a display mode and the current time. A region 214 or the like for displaying is provided.

  The map image is generated by reading out map data around the 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 based on the setting by the driver. On the map image displayed in the area 211, the host vehicle icon 31 and the target icon 32 are displayed in an overlapping manner. The own vehicle icon 31 is for indicating the position of the own vehicle with respect to the map image. The control unit 11 specifies the host vehicle position based on the position information output from the GPS receiving unit 13, and displays the host vehicle icon 31 superimposed on a portion corresponding to the host vehicle position in the map image.

  The target icon 32 is for indicating the position where the notification object is installed with respect to the map image. The graphic displayed inside the target icon 32 indicates the type of notification object. The control unit 11 specifies the position of the notification object based on the second DB, and displays the target icon 32 on the portion of the map image corresponding to the position of the notification object. In addition, a graphic indicating the type of notification object is displayed inside the target icon 32. Further, the type of the notification object and the distance to the notification object are displayed in area 212.

  Moreover, the control part 11 reads the data of a schematic diagram or a photograph from 2nd DB according to the kind of alerting | reporting object, when the distance between the own vehicle and alerting | reporting object becomes smaller than predetermined distance, and map image Overlaid on the display. In addition, audio data corresponding to the notification object 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 photo data of the speed measuring device is read from the second DB and displayed superimposed on the map image. Further, the voice “500m ahead speed measurement device. Speed attention” is read from the second DB and output from the speaker 15.

  Further, 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 radio signal received by the radio receiver 12. For this reason, the control part 11 can judge whether the distance between the own vehicle and alerting | reporting object became smaller than predetermined distance by comparing RSSI and a predetermined threshold value. When the control unit 11 determines that the distance between the host vehicle and the notification target is smaller than the predetermined distance, the control unit 11 reads out schematic diagram or photo data from the second DB according to the type of the notification target, Display overlaid on the image. In addition, audio data corresponding to the notification object is read from the second DB and output from the speaker 15. For example, when an emergency vehicle approaches within a predetermined distance, a schematic diagram or photo data of the emergency vehicle is read from the second DB and displayed on the map image. In addition, the voice “Emergency vehicle. Speed attention” is read from the second DB and output from the speaker 15.

  As described above, the driving support system 1 can notify the driver that there is a notification object near the host vehicle. By visually recognizing the main display area 21, the driver can recognize that there is a notification object near the host vehicle. The notification object is often installed in a dangerous place where a traffic accident is likely to occur. Accordingly, the driving support system 1 prompts the driver to drive safely in a place where a traffic accident is likely to occur by notifying the driver through the main display area 21 that the own vehicle is approaching the notification target. ing.

  Further, since the map image is displayed in the main display area 21, the driver can recognize geographical information around the host vehicle. For example, by recognizing the surrounding road environment, the driver can reduce the traveling speed in advance or pay sufficient attention to the surrounding environment in advance. In this way, the driving support system 1 can provide the driver with information necessary for the safe driving of the driver together with the traffic monitoring information.

  In addition, the control part 11 aligns between the own vehicle icon 31 and the target icon 32 displayed on the area | region 211 among the main display areas 21, and a map image, and displays it synchronizing. Specifically, it is as follows. The display position of the host vehicle icon 31 is fixed to the lower central part of the region 211. The map image is rotated so that the traveling direction of the vehicle is on the upper side. That is, when the traveling direction of the host vehicle changes (turns), the map image is also rotated accordingly. When the host vehicle moves forward, the displayed map image is scrolled downward (so-called heading-up display). Such display control can be realized by using map display control in the car navigation system, that is, control for appropriately scrolling the map image while the position of the host vehicle is fixed at the center of the screen. it can.

  The first sub display area 22 will be described. The first sub-display area 22 displays the name of the partition area where the host vehicle is located. Based on the position information output from the GPS receiving unit 13, the control unit 11 refers to the first DB to identify region identification information of the partitioned region where the host vehicle is located. The name of the partition area identified by the identified area identification information is displayed in the first sub display area 22. The driver can recognize the partition area where the host vehicle is located by visually recognizing the name displayed in the first sub display area 22.

  The second sub display area 23 will be described. In the second sub display area 23, a message regarding the monitoring activity is displayed. This message is created based on the traffic monitoring 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 the content of the public control information published by each prefectural police is different, the displayed content varies depending on the prefectural government. When the number of traffic monitoring information included in the message is 2 or more, the number of characters in the message increases, so that the control unit 11 displays the message in the second sub-display area 23 with a telop.

  A specific example of the message displayed in the second sub display area 23 will be described with reference to FIGS. 4 and 5. As shown in FIG. 4, the message 41 includes a plurality of phases (first phase 42 and second phase 43) divided for each category of traffic monitoring information. The first phase 42 and the second phase 43 include one or more traffic monitoring information. When a plurality of traffic monitoring information is included in one phase, these are arranged in order. In FIG. 4, “*** information” and “++++ information” correspond to traffic monitoring information. A title is added to the head of each phase. The title indicates an outline of the traffic monitoring information included in each phase. In this way, the message is created by classifying a plurality of traffic monitoring information to be notified to the driver for each category, and is displayed in the second sub display area 23. The driver can easily recognize the information related to the monitoring activity for each category. Note that the number of characters that can be registered in one phase is limited to, for example, 128 full-width characters (256 bytes in terms of bytes). This makes it possible for the driver to grasp the contents even without driving. When the number of characters that can be registered in one phase exceeds 128 characters, the traffic monitoring information is further classified into more detailed categories.

  For example, in FIG. 5, the title is divided into a first phase whose title is “<< public control information Aichi Prefectural Police >>” and a second phase whose title is “<< traffic regulation information Aichi Prefectural Police >>”. In the first phase, information on “control” (corresponding to the traffic monitoring information of indexes 2 and 3 in FIG. 2) is stored.

  If the created message does not fit in the second sub display area 23, the message is scrolled. When the driver visually recognizes the display unit 14 during driving, the driver cannot keep watching the display unit 14 for a long time during driving. Therefore, when many messages are displayed on the display unit 14 at once, the driver This is because the message may not be recognized correctly. On the other hand, in the driving support system 1, the text-based message created based on the traffic monitoring information is classified for each category and scroll-displayed in the second sub-display area 23, thereby displaying the second sub-display area 23. It is possible to reduce the amount of information of messages displayed at one time and increase the characters of the displayed text. Thus, the driver can accurately recognize the message displayed in the second sub display area 23 even when the display unit 14 is repeatedly viewed 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, *** information (first case), *** information (second case)) is displayed in the second sub display area 23. When the display area 23 is sequentially scrolled and the scroll display of the first phase 42 is completed, the second phase 43 is entered. When there are no remaining phases, scroll display is repeated in order from the first phase 42. Since the scroll display is repeatedly executed a plurality of times, the driver can recognize the repeatedly displayed message even if the driver has missed the message once.

  Note that the title of the first phase 42 in the message is first displayed in the second sub display area 23, and at the same time, an alarm sound (pyrroline, pyrroline) is output from the speaker 15. Thus, the driver can know that the traffic monitoring information is displayed in the second sub display area 23.

  Furthermore, when the vehicle travels and the partition area where the vehicle is located changes and the message displayed in the second sub display area 23 is updated, an alarm sound is similarly output from the speaker 15. Accordingly, the driver can recognize the updated message reliably by visually checking the display unit 14 when the notification is given by the alarm sound. In this way, the driving support system 1 can prevent the driver from overlooking the updated message.

  Moreover, the control part 11 changes the scroll speed in the case of scroll-displaying a message on the 2nd sub display area 23 according to the traveling speed of a vehicle. For example, when the traveling speed of the vehicle is high, it is assumed that the driver cannot direct his / her line of sight to the display unit 14 for a long time. In such a case, the display speed when the message is scroll-displayed is reduced so that the driver can understand even a single sentence. Thus, the driver can surely recognize the displayed message within a short time. On the other hand, for example, when the traveling speed of the vehicle is low, it is assumed that the driver can turn his / her eyes on the display unit 14 for a relatively long time. In such a case, the display speed when scrolling the message is increased. As a result, the driver can accurately recognize a large number of messages. Further, while the vehicle is stopped, the display speed when the message is scroll-displayed is further increased so that other public control information can be seen.

  Moreover, since the name of the division area in which the vehicle is located is displayed in the first sub display area 22, the driver may recognize the message displayed in the second sub display area 23 and the division area together. it can. Thus, for example, when the monitoring activity is performed over a wide area, the driver can confirm which portion of the entire area where the monitoring activity is performed corresponds to the position of the own vehicle. For example, it is assumed that a route is announced as an area where monitoring activities are performed. It is assumed that the host vehicle moves and the host vehicle enters a section area where the announced route is arranged. In the first sub-display area 22, the name of the partition area where the host vehicle is located is displayed. A message including the announced route is displayed in the second sub-display area 23. By referring to the map image displayed in the main display area 21, the driver can easily identify the location of the route included in the message from the section area having the name displayed in the first sub-display area 22. can do. Thus, the driver can recognize the positional relationship between the host vehicle and the route. By determining whether or not the own vehicle is approaching the route, the driver can grasp a place where particular attention should be paid to safe driving and can perform driving.

  With reference to FIG. 6, the main process performed in the control part 11 is demonstrated. When the driving support system 1 is turned on, the main process is executed by the control unit 11 executing the program stored in the ROM. When the main process is started, first, position information output from the GPS receiver 13 is acquired. By specifying the latitude and longitude of the vehicle position based on the acquired position information, the vehicle position on the map image is specified (S10). Subsequently, by referring to the first DB stored in the storage unit 16 based on the acquired position information, the area identification information of the section area where the host vehicle is located is acquired (S11). The acquired area identification information is stored in the RAM.

  A surrounding map image including the vehicle position is generated based on the map data stored in the storage unit 16. The generated map image is displayed in the area 211 of the main display area 21 on the screen of the display unit 14 (S13). The size of the map image displayed in the area 211 is adjusted based on conditions preset by the driver. Subsequently, the vehicle icon 31 is superimposed and displayed on the portion of the displayed map image corresponding to the vehicle position specified in S10 (S15). By visually recognizing the map image and the own vehicle icon 31 displayed in the main display area 21, the driver can recognize the geographical information including the position of the own vehicle.

  Next, based on the area identification information acquired in S11, the name of the division area where the host vehicle is located is specified in units of municipalities. The name of the partitioned area is specified by referring to a correspondence table of area identification information and name stored in advance in the storage unit 16. The name of the specified partition area is displayed on the first sub display area 22 in the screen of the display unit 14 (S17). As a result, the driver can recognize the division area where the host vehicle is located on a municipal basis by visually recognizing the name displayed in the first sub display area 22. Subsequently, the current date and time and the current time are specified (S19). The current date and time and the current time are acquired from a real time clock (RTC) not shown. Subsequently, the third DB stored in the SD card 171 is read, and the traffic monitoring information stored in the third DB is referred to (S21). Then, a message to be displayed in the second sub display area 23 is created as follows based on the traffic monitoring information stored in the third DB read from the SD card 171.

  From the traffic monitoring information stored in the third DB read from the SD card 171, the traffic monitoring information in which the same area identification information as the area identification information specified in S 11 is associated as “implementation place” is extracted. Next, the period during which the monitoring activity is carried out based on the “start date”, “start time”, “end date”, “end time” (see FIG. 2) associated with the extracted traffic monitoring information Is identified. Then, traffic monitoring information that satisfies the condition that the current date and time specified in S19 are included in the specified period is selected.

  It is determined whether there is one or more traffic monitoring information selected by the above method (S23). If the selected traffic monitoring information does not exist (S23: NO), there is no message to be displayed in the second sub display area 23, so the process returns to S10. On the other hand, if there is one or more selected traffic monitoring information (S23: YES), a message to be displayed in the second sub display area 23 is created as follows based on the selected traffic monitoring information (S25).

  Sort and arrange the selected traffic monitoring information by category. A title indicating the outline of each category is added to the head of the text information arranged for each category. As the title, an optimum title is selected and used from a plurality of titles prepared in advance. For example, the optimum title is selected as follows. A table in which titles and categories are associated is stored in the storage unit 16 in advance. When the text information is divided and arranged for each category, the titles corresponding to the divided categories are specified by referring to the table stored in the storage unit 16. The identified title is added to the head of the arranged traffic monitoring information as an optimum title indicating the category. Thus, each phase constituting the message is created. The created message is stored in the RAM.

  Next, the traveling speed of the vehicle is specified (S27). The traveling speed may be specified based on an acceleration sensor (not shown), or may be specified based on OBD data acquired via an on-board diagnostics connector on the vehicle side. In accordance with the identified travel speed, the speed for scrolling the message created in S25 is determined. The speed is determined so that the display speed when the scroll display is inversely proportional to the acquired traveling speed is slow. The created message is scrolled and displayed in the second sub display area 23 at the determined speed (S29). As a result, even when the traveling speed of the vehicle is high and the display unit 14 cannot be viewed continuously for a long time, the driver can recognize the displayed message within a short time because the display speed is slow. . In addition, when the driving speed of the vehicle is slow and the driver can visually recognize the display unit 14 for a relatively long period of time, the display speed increases, so that a large amount of traffic monitoring information can be accurately recognized. Can do. When the message is scrolled for the first time in the second sub display area 23, an alarm sound is output from the speaker 15.

  It is determined whether or not the area identification information acquired in S11 has been changed with the movement of the host vehicle. Whether or not the area identification information has been changed is determined by whether or not the area identification information previously stored in the RAM is different from the area identification information stored this time. When the area identification information is changed, there is a possibility that the message created in S25 is newly updated. It is determined whether the message created in S25 is newly updated (S31). Whether or not the message has been updated is determined by whether or not the previously stored message in the RAM is different from the currently stored message. If the message created in S25 has not been changed (S31: NO), the process directly returns to S10. On the other hand, when the message is newly updated (S31: YES), an alarm sound is output from the speaker 15 (S33). Accordingly, the driver can surely recognize the newly updated message by visually recognizing the second sub display area 23 of the display unit 14 when notified by an alarm sound. In this way, the driving support system 1 prevents the driver from overlooking the updated message. The process returns to S10.

  In the main process, for example, a process of waiting for a predetermined time (for example, 1 second) after S23, S31, and S33 and then returning to S10 may be performed. Further, for example, in the main process, after S23, S31, and S33, a process of returning to S10 may be performed when the travel distance of the vehicle becomes a predetermined distance or more. Then, the host vehicle position may be repeatedly specified in S10, and the message may be repeatedly generated based on the specified host vehicle position. As a result, while reducing the processing load on the control unit 11, it is possible to accurately create and display a message regarding the monitoring activity and notify the user.

  As described above, the driving support system 1 can specify the section area where the host vehicle is located in units of municipalities based on the first DB stored in the storage unit 16. As a result, compared to the conventional system where the position of the vehicle is specified only on the expressway in units of prefectures, the position of the vehicle is specified in more detail on a municipal basis even on general roads. be able to.

  In addition, the driving support system 1 can specify a partition area that covers an area where the monitoring activity is performed based on the third DB stored in the SD card 171. The third DB stores traffic monitoring information associated with one or more area identification information. The area identification information of the division area where the host vehicle is located and the area identification information of the division area included in the traffic monitoring information are both determined on a municipal basis. Therefore, the driving support system 1 can uniformly identify whether or not the monitoring activity is being performed in the partitioned area where the host vehicle is located based on the third DB. Therefore, the driving support system 1 can easily and surely identify and notify the driver of a message of information related to the monitoring activity performed near the place where the host vehicle is actually located. In addition, the driving support system 1 can prevent a message of information related to monitoring activities being performed in an area away from the place where the host vehicle is located from being displayed. Only messages necessary for the driver are displayed on the display unit 14. Therefore, it is possible to prevent the driver from overlooking necessary information by displaying many unnecessary messages.

  The driving support system 1 allows a vehicle to enter a municipality that includes at least the announced area even if "~ inside of the station", "~" It can be specified whether or not. This is because the traffic monitoring information stored in the third DB is associated with the area identification information of the area where the monitoring activity is carried out in units of municipalities. Therefore, the driving support system 1 can create a message suitable for the position of the vehicle based on the traffic monitoring information and provide it to the driver. The driver can easily grasp the information related to the monitoring activities performed near the vehicle position.

  In addition, the control part 11 etc. which perform the process of S11 are corresponded to the "first acquisition means" of this invention. The control unit 11 or the like that performs the processes of S21 and S23 corresponds to the “second acquisition unit” of the present invention. The control unit 11 or the like that performs the process of S29 corresponds to the “first control unit” of the present invention. The control unit 11 or the like that performs the process of S19 corresponds to the “first specifying unit” of the present invention. The control unit 11 or the like that performs the process of S27 corresponds to the “second specifying unit” of the present invention.

  In addition, this invention is not limited to the above-mentioned embodiment, A various change is possible. For example, the driving support system 1 may be configured not to include the wireless reception unit 12. The driving support system 1 may grasp the distance between the notification target object and the vehicle based on the voltage level of RSSI output from a wireless reception unit attached to the outside. Further, the driving support system 1 may be configured not to include the GPS receiving unit 13. The driving support system 1 may grasp the vehicle position based on position information output from a GPS receiving unit attached to the outside. Further, 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 the external display by controlling the external display. The external display may be a display of a car navigation system attached to the vehicle, for example. 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 the vehicle.

  The content of the message notified to the driver is not limited to the public control information published by each prefectural police station. For example, the information (regulation content, route, address, month, date, etc.) published by each regional maintenance station Time).

The operator may create the third DB as follows based on the published public control information. When the published control information satisfies the conditions (1) and (3), or the conditions (2) and (3) are satisfied, the operator can obtain traffic monitoring information associated with various items. create.
(1) When the municipality where the monitoring activity is implemented is disclosed as public control information.
(2) When the jurisdiction or region where monitoring activities are implemented is publicly disclosed as public control information.
(3) When the date and time when monitoring activities are carried out is disclosed as public control information.

  In the above description, the operator has created the third DB including the traffic monitoring information based on the published public control information. The present invention is not limited to this. The third DB including the traffic monitoring information may be processed automatically by the server based on the public control information. Specifically, it may be carried out as follows.

  The public control information published via the website of each prefectural police station is acquired by a server connected to the Internet. For example, the server periodically checks the HP of each prefectural police station in the URL stored in advance (for example, once a day) to determine whether the public control information is updated. If the public control information has been updated, the public control information of the page with the URL is acquired. From the multiple public control information in the acquired public control information page, traffic monitoring information and each information to be associated with traffic monitoring information ("prefecture", "start date", "start time", "end date", "End time" and "jurisdiction") are extracted. A plurality of information in the page is extracted and associated with the traffic monitoring information to create information as shown in FIG. The created information is stored in the storage unit of the server.

  For example, “prefecture”, “jurisdiction”, “route”, etc., which are publicized by public control information, are the units of “implementation location” associated with traffic monitoring information. In many cases, it is different from the unit of the partition area defined in (1). In such a case, the server specifies an “implementation place” to be associated with the traffic monitoring information as follows.

  The server is published as public control information for each prefectural police, and is common to the area where surveillance activities are carried out (prefecture, jurisdiction, route, etc., hereinafter referred to as “public area”) and each prefectural police. A correspondence table in which the area identification information specified by the unit of the municipality, which is the unit of, is associated in advance is stored in the storage unit. The area identification information associated with the open area includes at least area identification information of the partitioned area where the monitoring activity is actually performed. For example, a plurality of area identification information may be associated with one public area. When the server acquires public control information from the HP of each prefectural police station, the server extracts a public area included in the acquired public control information. And the area | region identification information corresponding to the extracted open area is specified with reference to the corresponding | compatible table memorize | stored in the memory | storage part. The identified area identification information is associated with the traffic monitoring information as an “execution place”. The “prefecture”, “start date”, “start time”, “end date”, “end time”, and “jurisdiction” extracted from the public control information are associated with the traffic monitoring information. Traffic monitoring information associated with various types of information is stored in the storage unit. Note that the method for specifying the partition region is not limited to the above-described method.

  The driving support system 1 may provide the driver with information on not only the monitoring activity actually performed at the present time but also the monitoring activity to be performed in the near future. For example, the driving support device 1 may determine whether there is a monitoring activity that starts within one hour from the current time based on “date” and “time” associated with the traffic monitoring information. If there is traffic monitoring information associated with the corresponding “date” and “time”, a message may be created based on this traffic monitoring information and displayed on the display unit 14. This allows the driver to immediately recognize not only the monitoring activities that are being carried out near the location of the vehicle, but also the monitoring activities that may be carried out in the near future, and drive in places where traffic accidents are likely to occur. Can be done safely.

  The message displayed in the second sub-display area 23 includes information other than traffic monitoring information, for example, information on events such as reinforcement month, seasonal feeling, customs, road regulation information (construction regulation, traffic regulation due to disaster), etc. May be. For example, by displaying road regulation information, the driver can avoid a regulated route. Information other than the traffic monitoring activity is stored in the SD card 171 together with the third DB, and such information may be read out and stored in a message.

  The titles and traffic monitoring information stored in each phase in the message displayed in the second sub display area 23 are classified into the monitoring activities and the monitoring activities so that they can be easily understood even when they are continuously arranged and scrolled. You may classify | categorize with a background color or a color character for every period and the area where monitoring activity is implemented, or attach an icon to the head. Further, as shown in FIG. 4, the total number of cases may be added to the title and the number of pages may be added for each traffic monitoring information so that the entire message can be grasped.

  The driving support apparatus 1 may create a message to be displayed in the second sub display area 23 also in the following case. It is assumed that traffic monitoring information not associated with “implementation location” is stored in the third DB. From such traffic monitoring information, all the traffic monitoring information in which the same prefecture as the prefecture where the vehicle is located is associated as “prefecture” is extracted. Based on the “start date”, “start time”, “end date”, and “end time” (see FIG. 2) associated with the extracted traffic monitoring information, the period during which the monitoring activity is performed is specified. Within the specified period, the traffic monitoring information including the current date and time specified in S19 and the time is selected. Create a message based on the selected traffic monitoring information. The driving support device 1 selects traffic monitoring information related to monitoring activities carried out in the prefecture where the host vehicle is located, and creates a message.
