[0002]

Some types of car navigation devices include VICS (Vehicle Information and CV).
Some systems have a function of notifying the driver of a vehicle of traffic jam information by using an ommunication system). With this function, the driver can know the degree of traffic congestion such as traffic congestion distance, but can know the cause of traffic congestion (accident congestion, natural congestion, etc.) and the location where the cause is an accident. Can not.

[0003] In traffic information broadcast by radio broadcasting or the like, information such as the location and situation of an accident, secondary disaster and traffic congestion may be obtained in relatively detail. However, radio broadcast traffic information often deals only with relatively large-scale accidents that have occurred on specific highways such as expressways. There is also a problem that the real-time property of information is low.

[0004] The present invention has been made in view of the above circumstances, and an object of the present invention is to promptly notify other vehicles of information on the accident when an accident involving the vehicle occurs. It is an object of the present invention to provide an accident occurrence position notification system which can be used, and an in-vehicle device used for the system.

[0005]

According to the accident occurrence location notification system of the present invention, the reporting center sends the accident information reported from the on-vehicle device to the other vehicles due to the occurrence of the accident in the vehicle. Send to onboard device. Then, the in-vehicle device that has received the accident information notifies the occupant of the vehicle of the accident information.

That is, when an accident involving a vehicle occurs, an occupant of another vehicle can know information about the accident within a short time via the notification center. Then, when the location where the accident occurs is in the direction that the host vehicle is about to head, it is possible to cope with avoiding the location in advance and traveling. Therefore, it is possible to prevent the occurrence of a secondary disaster and to avoid being caught in traffic.

According to the second aspect of the present invention, the on-vehicle apparatus is configured to control the vehicle when the position of the vehicle included in the received accident information is within a predetermined range with respect to the current position of the own vehicle. Notify the crew. Therefore, the convenience can be improved by notifying the occupant of only the information of high importance.

According to the third aspect of the present invention, when the position of the received vehicle is on the route to the destination where the host vehicle is currently traveling, the on-vehicle device may determine the position of the vehicle. Since the travel route to the destination is re-searched so as to bypass the route, the travel route can be reset so as to avoid being caught in traffic or the like due to the occurrence of the accident.

According to the present invention, the reporting center can make a report according to the type of radio communication means used by the vehicle-mounted device for each vehicle. Even if the means are different from each other, for example, such as an automobile telephone device, a mobile telephone device, or a PHS, by registering them in the reporting center, a report corresponding to any of them can be made. .

In some cases, detailed information such as the location of the accident and the situation of the accident may be obtained by directly talking with the occupant. Then, the public center 4 contacts the police headquarters 6 or the firefighting headquarters 7 according to the situation, and requests the dispatch of an ambulance or a patrol car.
In addition, the private center 5 contacts the service company 8 or the hospital 9 that provides services such as emergency repair of vehicles and tow trucks as necessary, and requests the provision of necessary services and the acceptance of injured persons.

FIG. 3 is a functional block diagram showing an electrical configuration of the emergency notification device 2. FIG. 2 is a side view showing a state in which the emergency notification device 2 is mounted on the automobile 1 with a part thereof cut away and transparent. FIG. The navigation device (position detecting means) 10 disposed on the rear side of the vehicle receives a GPS signal transmitted from a GPS satellite via a GPS antenna 10a. The positioning operation unit 11 receives the received GPS
The autonomous navigation unit 12 detects the absolute position of the car 1 from the signal.
Detects the relative position of the vehicle 1 based on a sensor signal provided from a sensor unit 13 including a direction sensor and a distance sensor. Then, the positioning calculation unit 11 and the autonomous navigation unit 12 output the position information detected by each to the control unit 14.

The control unit 14 is mainly composed of a microcomputer, and detects the current position of the vehicle 1 based on the position information provided by the positioning calculation unit 11 and the autonomous navigation unit 12. Then, for example, the map data near the current position is read from the data storage unit 15 composed of a CD-ROM and its driver and displayed on the screen of the display 16, and necessary items and the like are given to the occupant of the automobile 1. The notification is performed by voice via the voice output unit 30. Further, the control unit 14 controls an in-vehicle L (not shown).
It is connected to the in-vehicle LAN 17 via the AN interface, and can communicate with the information transmitting device 18 similarly connected to the in-vehicle LAN 17.

The information transmitting device 18 disposed between the driver's seat and the passenger seat is also constituted mainly by a microcomputer, and the device 18 includes a G sensor 1
9 is provided. The information transmitting device 18 has a built-in RTC (Real Time Clock) 18a, which is an IC having a clock function, and refers to the time at the time when the G sensor 19 outputs a trigger signal. Has become.

As shown in FIG. 2, for example, the G sensor 19 is built in the steering wheel central portion 1a of the automobile 1 together with the airbag device 20, and is installed in the automobile 1 when an accident such as a collision occurs in the automobile 1. The applied shock is detected as acceleration (G), and a trigger signal is output to the airbag device 20 when the acceleration is equal to or greater than a threshold.

Then, the airbag device 20 ignites the chemicals of the inflator and burns them to generate gas explosively, whereby the airbag (not shown) is rapidly inflated and deployed to be added to the driver's body. The system is designed to absorb the impact of an accident that may occur and to ensure the safety of the driver.

The information transmitting device 18 includes an in-vehicle LAN.
A mobile telephone device (wireless communication means) 21 is communicably connected via 17. The car telephone device 21 is arranged on the left side of the backrest of the driver's seat, is normally used as a car telephone, and is configured to enable hands-free communication. When an accident occurs, the telephone numbers of both centers 4 and 5 are stored in an internal memory (not shown) in order to make an emergency call by automatically calling the public center 4 and / or the private center 5.

Next, the operation of the present embodiment will be described with reference to FIGS. First, a user who uses the accident occurrence location notification system registers in the database of the private center 5. For example, as shown in FIG. 7, the number (A, B, C,...) Of each vehicle and, if necessary, the driver's name, address, gender, date of birth, blood type (not shown), A call number of a vehicle (such as a mobile phone or a PHS (Personal Handyphone System)) used as a wireless communication means, such as a car phone 21 shown in FIG. 3, is registered in the vehicle.

FIG. 4 is a flowchart showing the control contents of the information transmission device 18. The operation is started when a collision accident or the like occurs in the automobile 1 and a trigger signal is output from the G sensor 19. The information transmitting device 18 first obtains the time information at that time with reference to the RTC 18a (step A).
1) Subsequently, the current position information of the automobile 1 is acquired from the control unit 14 of the navigation device 10 via the in-vehicle LAN 17 (step A2). Then, the information transmitting device 18
Outputs the time information and the position information obtained in steps A1 and A2 to the automobile telephone device 21 via the in-vehicle LAN 17 and gives a command to make a call to the public center 4 and / or the private center 5 to cause the accident occurrence information. When the (accident information) is transmitted and an emergency call is made (step A3), the process ends.

Next, FIG. 5 is a flowchart showing the contents of the processing performed by, for example, an emergency call server (not shown) provided at the private center 5 side. The server of the private center 5 stands by until the accident occurrence information transmitted by any of the vehicles registered as the system user is received (step B1). And
When the accident occurrence information is received ("YES"), the accident occurrence information is transferred to other facilities such as the public center 4, the service company 8, and the hospital 9 to make an emergency contact (step B2).

Then, when the server of the private center 5 reads out the information of each vehicle registered in the database (step B3), the server of the private center 5 transmits the accident occurrence information to the other vehicles except the vehicle which transmitted the accident occurrence information. After transmission (step B4), the process returns to step B1. In this case, the information to be transmitted to the other vehicles relates to the time and location of the accident among the information received by the private center 5.

FIG. 6 is a flowchart showing the processing contents of the control unit 14 in the navigation device 10 mounted on each vehicle. If the car telephone device 21 does not receive the accident occurrence information transmitted from the private center 5 in step C1, the control unit 14 performs normal navigation processing in step C2. Then, upon receiving the accident occurrence information (step C1, "YES"),
The control unit 14 acquires the current position of the automobile 1 from the positioning calculation unit 11 (step C3), and determines whether the accident position included in the received accident information is close to the current position (step C4). . Here, for example, when the accident occurrence position is within a radius of 10 km from the current position as the center, it is determined to be “close”.

In step C4, when the control unit 14 determines that the accident occurrence position is far from the current position ("N
O ") Return to step C1. On the other hand, when determining that the accident occurrence position is close to the current position ("YES"), the control unit 14 notifies the automobile 1 of the accident occurrence information (step C5). The notification here is performed by marking and displaying the accident occurrence position on a map displayed on the screen of the display 16, simultaneously displaying the accident occurrence time on the screen, or by voice output from the audio output unit 30, for example, “1”.
At 6:35 an accident occurred on National Route 22. "
The notification is performed as shown in FIG.

Subsequently, if a travel route to the destination is set by the navigation function at that time (step C6, "YES"), the accident occurrence position is on the travel route. It is determined whether or not (Step C7). If the accident location is not on the traveling route ("NO"), the process proceeds to step C1, and if the accident location is on the traveling route ("YES"), the traveling route is detoured around the accident location. Is recalculated and displayed on the display 16 (step C8). Then, the process returns to step C1.

As described above, according to the present embodiment, the server of the private center 5 transmits an accident generated by the emergency notification device 2 mounted on the automobile 1 in response to the accident occurring on the automobile 1. The navigation device 10 of the emergency notification device 2 that has transmitted the information to the emergency notification device 2 mounted on the other vehicle 1 and received the accident occurrence information notifies the occupant of the vehicle 1 of the accident occurrence information. I did it.

Therefore, when an accident involving the vehicle occurs, the occupant of the other automobile 1 can know information about the accident within a short time. If the location of the accident is in the direction that the vehicle is heading in the future, it is possible to avoid the position in advance and run so that secondary accidents can be prevented or traffic jams can occur. Entanglement can be avoided.

When the navigation device 10 of the emergency notification device 2 determines that the accident occurrence position included in the received accident occurrence information is close to the current position of the vehicle, the navigation device 10 informs the occupant of the vehicle 1 of the accident. By reporting the accident occurrence information, only the information of high importance is reported to the occupant, so that the convenience can be improved.

Further, when the received accident location is on the route to the destination where the vehicle is currently traveling, the navigation device 10 changes the traveling route to the destination so as to bypass the accident location. Since the search is performed again, the traveling route can be set again so as to avoid being caught in traffic or the like due to the occurrence of the accident.

In addition, since the server of the private center 5 issues a report according to the type of wireless communication means used by the emergency notification device 2 for each vehicle, the wireless communication means may be, for example, an automobile telephone device 21 or a portable telephone. Even if they are different from each other such as a telephone device or a PHS, by registering them in the database of the private center 5, it is possible to make a report corresponding to any of them.

The present invention is not limited to the embodiment described above and shown in the drawings, and the following modifications or extensions are possible. The reporting center is not limited to the private center 5, and the public center 4 may have the function. In step C4, the criterion for judging whether or not the accident occurrence position is close to the current position may be changed as appropriate without being limited to “radius 10 km”. Further, it is also possible to configure so that the reporting center transmits the accident occurrence information only to the registered vehicle determined to be close to the location where the accident occurred on the reporting center side. In this case, step C4 becomes unnecessary. . The processes in steps C6 to C8 may be performed as needed. The processing in the private center 5 is not limited to processing performed automatically by a server or the like, and an operator may be involved in some of the processing. For example, if the operator can directly obtain information about the location of the accident and the situation of the accident by talking directly with the occupant of the car 1 that caused the accident via a wireless telephone line, the information is obtained. In addition to the accident occurrence information, the operator may contact another facility such as the public center 4, the police headquarters 6, or the firefighting headquarters 7. The information transmission device 18 is not limited to the device that automatically transmits the accident occurrence information, and may be configured so that the occupant of the vehicle performs the transmission by manual operation.
The in-vehicle device is not limited to the one in which the navigation device 10, the information transmitting device 18, and the car telephone device 21 are connected via the in-vehicle LAN 17, like the emergency notification device 2.
These functions may be integrated, or the information transmitting device 18 and the car telephone device 21 may be integrated.
May be configured as a navigation device to which the above function is added.
