  Next, the near-miss data generated in S104 is transmitted to the traffic information center 3 (S110), and the process returns to S100.

  Through the above-described processing, near-miss data is generated and transmitted to the traffic information center 3 every time either a sudden braking or a sudden steering operation is performed.

  When the server of the traffic information center 3 receives the near-miss data transmitted from each vehicle, it performs a process of classifying and storing for each vehicle form included in the near-miss data.

  Further, the operator of the traffic information center 3 performs an operation of creating alert data for summarizing the near-miss data stored in the server and alerting the driving operation in each place. Specifically, the alert announcement data is created based on the situation included in the near-miss data, and the alert condition for alerting is specified, and the alert data including the announcement data and the alert condition is stored in the server. To do.

  FIG. 4 shows the alert conditions. As shown in the figure, the conditions for alerting include position, date, time, vehicle speed, direction of travel, weather, temperature, and vehicle form, and the operator can specify the corresponding conditions. ing.

  For example, if a large number of near-miss data is stored in the server when the location is an intersection in a city and a large vehicle turns left, it is predicted that there are many near-miss incidents when turning left by large vehicles. , For example, create a warning announcement such as "Further, there is a lot of incidents involving left turns at the intersection 300 meters ahead. Please be careful." Various conditions are specified, such as designating the position to indicate the same “a certain urban area intersection” as the position included in the near-miss data, and designating the vehicle form as “large vehicle”. Then, “attention announcement data” and “condition to perform alert” are associated with each other and stored in the server as alert data.

  When a large number of near-miss data at the same point are stored in the server regardless of the vehicle form, the designation of the vehicle form is set to “all” and the alert data is stored in the server.

  FIG. 5 shows an example of a warning announcement when various near-miss data are received. As shown in the figure, various attention announcement data are created according to the near-miss data.

  The navigation device 1 according to the present embodiment communicates with the traffic information center 3 to acquire only alert data corresponding to the vehicle form of the vehicle around the vehicle position from the traffic information center 3 and notify the occupant. carry out.

  Next, with reference to FIG. 6, the process of the server installed in the navigation apparatus 1 and the traffic information center 3 mounted in the vehicle will be described. The navigation device 1 enters an operating state when the ignition switch of the vehicle is turned on, and the control circuit 17 starts the processing shown in FIG. Further, when the server of the traffic information center 3 is instructed to execute a specific program after the power is turned on, it starts the processing shown in FIG.

  The navigation device 1 first transmits vehicle information to the traffic information center 3 (S300). Specifically, the vehicle form of the mounted vehicle is acquired from the electronic license plate 2, and vehicle information obtained by adding the vehicle form to the vehicle identification information is transmitted to the traffic information center 3.

  Next, the current location information obtained by adding the current location of the vehicle to the vehicle identification information is transmitted to the traffic information center 3 (S302).

  On the other hand, the server of the traffic information center 3 determines whether vehicle information is received from the vehicle (S400).

  When vehicle information is not received, determination of S400 becomes NO and repeats determination of S400.

  Further, when vehicle information is received from the vehicle, current location information from the vehicle is received (S402). Next, based on the received vehicle information and current location information, the vehicle form of the vehicle that has transmitted these information, and the current location of the vehicle The date and time when the information is received (reception date and time) and the vehicle identification information are stored in the storage medium (S404).

  Next, the alert data corresponding to the conditions (vehicle form of the vehicle, current location of the vehicle, reception date and time) stored in the storage medium in S404 is searched from the database, and it is determined whether there is such data (S406). ). Specifically, using a certain range including the current location of the vehicle as a search area, the alert data corresponding to the conditions such as the vehicle form, the reception date and time is searched from the database, and it is determined whether or not the corresponding data exists.

  Here, if the corresponding alert data is retrieved, the retrieved alert data is transmitted to the vehicle (S408).

  As described above, the server of the traffic information center 3 transmits only the alert data corresponding to the vehicle form of the vehicle that has transmitted the vehicle information and the current location information to the vehicle. If the corresponding alert data is not retrieved, the process returns to S402 without transmitting the alert data.

  When the control circuit 17 of the navigation device 1 mounted on the vehicle receives the alert data corresponding to the vehicle form of the own vehicle from the server of the traffic information center 3 (S304), the received alert data is It is determined whether or not the notification is for alerting the driver about the road on which the vehicle travels on a daily basis (S306). This determination can be made by referring to the traveling history of the vehicle stored in the storage medium in S108 of FIG. For example, when the alert data is for notifying the alert at a point on the road that has traveled within one week, it is for notifying the alert regarding the road on which the vehicle travels on a daily basis. It is determined that

  Here, if it is determined that the received alert data is for alerting the user about the road on which the vehicle runs on a daily basis, the process proceeds to S302 without performing alert notification. Return. That is, alerting notification is prohibited.

  In addition, if it is determined that the received alert data is not for informing the alert regarding the road on which the vehicle is traveling on a daily basis, the received alert data is It is determined whether or not the notification is made (S308). The control circuit 17 of the navigation apparatus 1 stores the notified history in the memory 14 when performing notification for alerting based on the alerting data. The control circuit 17 refers to the history stored in the memory 14 and determines whether or not the received alert data has been previously notified by the own vehicle.

  If it is determined that the received alert data has been previously reported by the vehicle, the process returns to S302 without performing alert notification. That is, alerting notification is prohibited.

  If it is determined that the received alert data is not previously reported by the host vehicle, it is then determined whether the vehicle speed of the host vehicle is faster than the vehicle speed included in the received alert data. (S310).

  Here, when the vehicle speed of the own vehicle is equal to or lower than the vehicle speed included in the received alerting data, the determination in S310 is NO, and the process returns to S302 without performing alerting notification. That is, alerting notification is prohibited.

  If the vehicle speed of the host vehicle is faster than the vehicle speed included in the received alert data, the determination in S310 is YES, and then the weather included in the received alert data matches the weather around the host vehicle. It is determined whether or not (S312). To determine whether the weather matches, the wiper information (wiper on, wiper off) included in the received alert data is compared with the wiper information (wiper on, wiper off) input to the control circuit 17. Can be performed.

  Here, when the weather included in the received alerting data does not match the weather around the host vehicle, the determination in S312 is NO, and the process returns to S302 without performing alerting notification. That is, alerting notification is prohibited.

  If the weather included in the received alert data does not match the weather around the host vehicle, the determination in S312 is YES, and then the temperature included in the received alert data matches the temperature around the host vehicle. It is determined whether or not (S314). The determination as to whether or not the temperatures match can be made by determining whether or not the vehicle outside temperature input to the control circuit 17 is included in the temperature range included in the received alert data.

  Here, when the temperature included in the received alerting data does not match the ambient temperature of the vehicle, the determination in S314 is NO, and the process returns to S302 without performing alerting notification. That is, alerting notification is prohibited.

  If the temperature included in the received alert data matches the temperature around the vehicle, the determination in S314 is YES, and then whether the current time is included in the time zone included in the received alert data. Is determined (S316). To determine whether the current time is included in the time zone included in the alert data, determine whether the current time specified using the timer for time management is included in the received alert data This can be done.

  If the current time is not included in the time zone included in the received alert data, the determination in S316 is NO, and the process returns to S302 without performing alert notification. That is, alerting notification is prohibited.

  If the current time is included in the time zone included in the received alert data, the determination in S316 is YES, and then alert notification based on the received alert data is performed (S318). Specifically, a warning announcement included in the warning data is displayed at a position on the map indicated by the warning data, and the warning announcement is output from the speaker 16 as a voice.

  As described above, only the alert data corresponding to the vehicle form of the vehicle in the vicinity of the vehicle position is acquired from the traffic information center 3 as the vehicle travels, and the alert is based on the acquired alert data. Is to be notified.
