  The low speed operation threshold value is a speed threshold value that is referred to when low speed operation is detected. The high-speed driving threshold is a speed threshold that is referred to when high-speed driving is detected. The roadside belt travel threshold is a threshold value of the number of times referred to when detecting roadside belt travel. In the example of FIG. 7, a vehicle in which the traveling lane is a roadside belt is detected as a vehicle that is traveling on a roadside belt continuously five times.

  The meandering operation threshold value is a threshold value of the number of lane changes referred to when detecting meandering operation. In the example of FIG. 7, a vehicle that has changed lanes five or more times consecutively is detected as a vehicle performing meandering operation.

  Each threshold stored in the driving threshold table 214 is an example, and can be arbitrarily set. For example, the settings of the low-speed driving threshold, the high-speed driving threshold, etc. may be arbitrarily changed depending on the weather.

  FIG. 8 is a diagram illustrating an example of a lane position conversion table. In the lane position conversion table 215 of the present embodiment, north latitude, east longitude, kilometer post information, lane position information, and traveling direction are associated. The lane position conversion table 215 of this embodiment is a table given in advance for each road.

  FIG. 13 is a flowchart for explaining vehicle sensor information acquisition processing. FIG. 13 shows details of the process in step S1201 of FIG.

  The vehicle information output server 200 of this embodiment acquires the north latitude value from the position information acquired from the GPS sensor 11 via the radio base station 500 by the information acquisition unit 221, and the north update value by the table update unit 225. Is stored in the vehicle sensor information table 211 (step S1301). Subsequently, the vehicle information output server 200 acquires the value of east longitude from the position information acquired from the GPS sensor 11 via the radio base station 500 by the information acquisition unit 221, and the value of east longitude by the table update unit 225 It stores in the sensor information table 211 (step S1302).

  Subsequently, the vehicle information output server 200 stores, in the vehicle sensor information table 211, the time when the GPS sensor 11 acquires the position information as the collection date / time by the table update unit 225 (step S1303), and ends the process.

  FIG. 14 is a flowchart for explaining vehicle speed calculation processing and travel lane calculation processing. FIG. 14 shows details of the process in step S1202 of FIG.

  The vehicle information output server 200 of this embodiment reads the vehicle sensor information acquired last time from the vehicle sensor information table 211 by the analysis part 222 (step S1401). Subsequently, the vehicle information output server 200 refers to the lane position conversion table 215 by the analysis unit 222, obtains kilopost information corresponding to the vehicle position information acquired this time, and enters the vehicle sensor information table 211 by the table update unit 225.

Further, the vehicle information output server 200 uses the vehicle speed calculation unit 226 to obtain a difference between the previous collection date and time of the vehicle sensor information and the collection date and time of the vehicle sensor information acquired this time. Then, the vehicle speed calculation unit 226 calculates the vehicle speed from the difference between the two. The calculated speed is stored in the vehicle sensor information table 211 by the table updating unit 225 (step S1403).

  Next, the vehicle information output server 200 refers to the lane position conversion table 215 by the lane position determination unit 227 and acquires lane position information corresponding to the position information included in the vehicle sensor information read this time. The acquired lane position information is stored in the vehicle sensor information table 211 by the table updating unit 225 (step S1404).

  Next, with reference to FIG. 15, event occurrence notification processing relating to roadside belt traveling will be described. FIG. 15 is a flowchart for explaining event occurrence notification processing relating to roadside belt traveling. FIG. 15 shows details of the processing in step S1203 of FIG.

  The vehicle information output server 200 acquires the latest n times lane position information from the vehicle sensor information table 211 by the driving state detection unit 228. In addition, the vehicle information output server 200 acquires a roadside belt travel threshold value with reference to the driving threshold value table 214 by the driving state detection unit 228 (step S1501).

  Subsequently, the vehicle information output server 200 determines whether or not the number of times that the lane position information is continuously a roadside band in the acquired lane position information is greater than the roadside band travel threshold by the driving state detection unit 228. (Step S1502).

  In step S1502, when the number of times of being a roadside belt continuously is equal to or less than the roadside belt running threshold, the driving state detection unit 228 ends the process.

  In step S1502, when the number of times of being a roadside belt continuously is greater than the roadside belt running threshold, the driving state detection unit 228 uses the table update unit 225 to set “roadside information” as the predicted event information value in the road monitoring information table 212. Stores “Side Zone Travel”.

  In addition, the driving state detection unit 228 stores, as the value of the position information in the road monitoring information table 212, the kilopost information in which the vehicle running in the roadside zone is detected by the table update unit 225. And the driving | running state detection part 228 acquires the display comment corresponding to roadside belt driving | running | working with reference to the occurrence event table 213, and stores it as the value of the display comment of the road monitoring information table 212 by the table update part 225 (step). S1503).

  Thus, in the present embodiment, for example, when the number of times the value of the lane position information is continuously the roadside band is larger than the roadside band running threshold, the vehicle travels in the roadside band for a predetermined time or more. It is assumed that the vehicle is traveling and the roadside zone is detected.

  Next, with reference to FIG. 16, event occurrence notification processing related to meandering operation will be described. FIG. 16 is a flowchart for explaining event occurrence notification processing related to meandering operation. FIG. 16 shows details of the process in step S1204 of FIG.

  The vehicle information output server 200 acquires the latest n times lane position information from the vehicle sensor information table 211 by the driving state detection unit 228. In addition, the vehicle information output server 200 acquires the meandering driving threshold value with reference to the driving threshold value table 214 by the driving state detection unit 228 (step S1601).

  Subsequently, the vehicle information output server 200 determines whether or not the number of times the lane position information is continuously changed in the lane position information is larger than the meandering driving threshold by the driving state detection unit 228. (Step S1602).

  In step S1602, when the number of times the lane is continuously changed is equal to or less than the meandering operation threshold value, the driving state detection unit 228 ends the process.

  In step S1602, when the number of times the lane is continuously changed is larger than the meandering driving threshold, the driving state detecting unit 228 uses the table updating unit 225 to set the predicted event information value of the road monitoring information table 212 as “ "Meandering operation" is stored.

  In addition, the driving state detection unit 228 stores, as the value of the position information in the road monitoring information table 212, the kilopost information in which the vehicle performing the meandering operation is detected by the table update unit 225. And the driving | running state detection part 228 acquires the display comment corresponding to meander driving | operation with reference to the occurrence event table 213, and stores it as the value of the display comment of the road monitoring information table 212 by the table update part 225 (step S1603). ).

  Thus, in the present embodiment, for example, when the number of times of lane change continuously from the lane position information is larger than the meandering operation threshold, the corresponding vehicle changes the lane many times within a predetermined time. Is detected as meandering operation.

  In the present embodiment, the meandering operation is detected based on the position information, but the present invention is not limited to this. In the present embodiment, for example, when it is detected that the driver has operated the steering wheel a predetermined number of times or more within a certain time, the meandering operation may be detected.

  In the present embodiment, the event occurrence notification process related to the meandering operation may be performed more frequently than the other event notification processes. In the present embodiment, by increasing the frequency of performing the event occurrence notification process related to the meandering operation, the meandering operation for finely changing the lane can be detected.

  In this case, the interval for executing the process shown in FIG. 12 is shortened, and only the event occurrence notification process related to the meandering operation may be executed every time the process of FIG. 12 is executed.

  Hereinafter, for example, a case where the process of FIG. 12 and the event notification process related to meandering operation are performed at intervals of 5 seconds and another event notification process is performed at intervals of 20 seconds will be described. In this case, the vehicle information output server 200 first executes the process of FIG. 12 and executes all event notification processes. Next, when the vehicle information output server 200 executes the process of FIG. 12, the vehicle information output server 200 skips the event notification process other than the event notification process related to the meandering operation. The vehicle information output server 200 may repeat this skip three times and then execute all the event notification processes again when executing the process of FIG.

  Next, with reference to FIG. 17, event occurrence notification processing relating to low-speed driving will be described. FIG. 17 is a flowchart for explaining event occurrence notification processing relating to low-speed driving. FIG. 17 shows details of the processing in step S1205 of FIG.

  The vehicle information output server 200 acquires the latest speed from the vehicle sensor information table 211 by the driving state detection unit 228. In addition, the vehicle information output server 200 acquires a low-speed driving threshold value with reference to the driving threshold value table 214 by the driving state detection unit 228 (step S1701). Subsequently, the vehicle information output server 200 determines whether or not the acquired speed is slower than the low speed driving threshold by the driving state detection unit 228 (step S1702).

  In step S1702, when the speed is equal to or higher than the low speed driving threshold, the driving state detecting unit 228 ends the process.

  In step S1702, when the speed is slower than the low speed driving threshold, the driving state detection unit 228 determines whether or not the driving state of the vehicle is a low speed driving state due to dangerous driving (step S1703).

  In step S1703, when it is not the low speed driving by the dangerous driving, the driving state detecting unit 228 ends the process. In addition, the case where it is not the low speed driving | running | working by dangerous driving | running | working is a case where the traffic congestion has generate | occur | produced around the applicable vehicle, for example. In the present embodiment, for example, when the vehicle speed is a predetermined speed or more and a predetermined speed or less, or when all the vehicles around the vehicle (for example, front, back, left, and right) are stopped, the vehicle travels. It may be a traffic jam on the road.

  In step S <b> 1703, when it is a low speed driving due to a dangerous driving, the vehicle information output server 200 stores “low speed driving” as the value of the predicted event information in the road monitoring information table 212 by the table updating unit 225.

  In addition, the driving state detection unit 228 stores kilopost information in which the table updating unit 225 detects the vehicle that is driving at low speed as the position information value of the road monitoring information table 212. And the driving | running state detection part 228 acquires the display comment corresponding to low speed driving | operation with reference to the occurrence event table 213, and stores it as the value of the display comment of the road monitoring information table 212 by the table update part 225 (step S1704). ).

  As described above, in the present embodiment, the accuracy of performing the danger notification can be improved by omitting the low-speed driving caused by traffic congestion or the like from the driving state to be detected.

  Next, with reference to FIG. 18, event occurrence notification processing relating to high-speed driving will be described. FIG. 18 is a flowchart for explaining event occurrence notification processing relating to high-speed driving. FIG. 18 shows details of the process in step S1206 of FIG.

  The vehicle information output server 200 acquires the latest speed from the vehicle sensor information table 211 by the driving state detection unit 228. In addition, the vehicle information output server 200 acquires a high-speed driving threshold value with reference to the driving threshold value table 214 by the driving state detection unit 228 (step S1801). Subsequently, the vehicle information output server 200 determines whether or not the acquired speed is slower than the high speed driving threshold by the driving state detection unit 228 (step S1802).

  In step S1802, when the speed is slower than the high-speed driving threshold, the driving state detection unit 228 ends the process.

  In step S1802, when the speed is equal to or higher than the high speed driving threshold, the vehicle information output server 200 stores “high speed driving” as the value of the predicted event information in the road monitoring information table 212 by the table updating unit 225.

  In addition, the driving state detection unit 228 stores kilopost information in which the vehicle performing high-speed driving is detected as the value of the position information in the road monitoring information table 212 by the table update unit 225. Then, the driving state detection unit 228 refers to the occurrence event table 213, acquires a display comment corresponding to high-speed driving, and stores it as a display comment value in the road monitoring information table 212 by the table update unit 225 (step S1803). ).

  Next, display instruction processing will be described with reference to FIG. FIG. 19 is a flowchart illustrating the danger notification display instruction process. FIG. 19 shows details of the processing in step S1208 of FIG.

  The vehicle information output server 200 of the present embodiment refers to the road monitoring information table 212 by using the display instruction unit 224, and acquires the latest record stored in the road monitoring information table 212 (step S1901). The record includes a display comment, a display start date / time, a display end date / time, position information, and predicted event information.

  Subsequently, the vehicle information output server 200 refers to the notification range table 217 by the notification range determination unit 223 and acquires a notification range corresponding to the predicted event information (step S1902). Specifically, in the present embodiment, for example, when the predicted event information is “high-speed driving”, the range is XX km from the kilometer post information specified by the position information.

  Moreover, in this embodiment, when prediction event information is "low-speed driving | operation", it becomes the range of xx kilometers toward the back from the kilometer post information specified by position information.

  Subsequently, the vehicle information output server 200 refers to the information board table 216 by the notification range determination unit 223 and acquires the information board ID of the information board 300 installed in the notification range (step S1903). Specifically, the notification range determination unit 223 according to the present embodiment specifies kilopost information corresponding to the notification range on a road within the notification range designated in step S1902. And the notification range determination part 223 acquires information board ID corresponding to the specified kilo post information in the information board table 216.

  Subsequently, the vehicle information output server 200 instructs the display instruction unit 224 to display a display comment (danger notification) from the display start date to the display end date with respect to the information plate 300 corresponding to the acquired information plate ID. Similarly, the display instruction unit 224 instructs the monitor display 400 to display a display comment (step S1904).

  As described above, in this embodiment, when it is detected that the vehicle is in a predetermined driving state, the notification range of the danger notification is determined according to the driving state of the vehicle. Therefore, in the present embodiment, it is possible to optimize the notification range of the notification that prompts the avoidance of danger.

  In the above example, the notification range determination unit 223 determines the notification range with reference to the notification range table 217, but the present invention is not limited to this. In this embodiment, the notification range of the danger notification may be adjusted depending on, for example, whether or not there is a traffic jam on the road.

  The notification range of the danger notification may be narrower when traffic congestion occurs on the road than when traffic congestion does not occur. In addition, it is preferable to widen the notification range of the danger notification when there is no traffic jam on the road.

  Below, the example which adjusts a notification range is demonstrated. FIG. 20 is a flowchart illustrating another example of the danger notification display instruction process.

  The processes in steps S2001 and S2002 in FIG. 20 are the same as the processes in steps S1901 and S1902 in FIG.

  The vehicle information output server 200 uses the notification range determination unit 223 to determine whether or not there is a traffic jam on the road within the notification range acquired in step S2002 (step S2003). Note that the determination of whether or not a traffic jam has occurred is as described in the event occurrence notification process related to low-speed driving.

  If there is no traffic jam in step S2003, the process proceeds to step S2006, which will be described later.

  In step S2003, when a traffic jam has occurred, the notification range determination unit 223 identifies a road in which the traffic jam has occurred within the notification range (step S2004). Subsequently, the notification range determination unit 223 adjusts the notification range on the road where the traffic jam has occurred (step S2005).

  The notification range adjustment will be described below.

  For example, when a traffic jam occurs, the notification range determination unit 223 of the present embodiment may set a distance obtained by subtracting a predetermined distance set in advance from the notification range acquired in step S2002. Specifically, for example, when the predicted event information is “meandering operation”, the notification range is XX kilometers forward from the kilometer post information specified from the position information. In addition, the predetermined distance to be subtracted when a traffic jam occurs is set to ● kilometers. In this case, the notification range is “XX- ●” kilometers. The predetermined distance may be set in stages according to the speed of the vehicle at the time of traffic jam.

  The processes in steps S2006 and S2007 in FIG. 20 are the same as the processes in steps S1903 and S1904 in FIG.

  As described above, in the present embodiment, the notification range of the danger notification can be determined according to the driving state of the vehicle performing the dangerous driving and the road condition.

  In the example of FIG. 20, the example in which the predetermined distance is subtracted from the notification range acquired from the notification range table 217 according to the presence or absence of traffic congestion has been described, but the present invention is not limited to this. In the present embodiment, when there is no traffic jam, a predetermined distance set in advance may be added to the notification range acquired from the notification range table 217.

  Moreover, although this embodiment demonstrated the example which adjusts a notification range according to the presence or absence of traffic congestion, it is not limited to this.

  The notification range may be adjusted according to, for example, the weather, a road speed limit set when dangerous driving is detected, or the like. For example, when the weather is rainy or snowy, the notification range may be narrower than the notification range acquired from the notification range table 217. In this case, the display start date and time and the display end date and time of the display comment may be adjusted.

  The notification range may be adjusted so that the notification range is wider than the notification range acquired from the notification range table 217, for example, when the speed limit is set to a predetermined speed or higher.
