Description

  The present invention relates to a vehicle accident information transmission device and a vehicle accident information transmission method for transmitting accident information to the outside when an accident occurs in a vehicle.

  In recent years, with the aim of advanced navigation systems, establishment of automatic toll systems such as toll roads, support for safe driving, optimization of traffic management, and efficiency of road management, ITS (Intelligent Transportation System) that builds a vehicle as an integrated system has been developed and put into practical use.

  In addition, in order to realize a so-called smart car that is a tray on the vehicle side of ITS, development of ASV (Advanced Safety Vehicle) is also being promoted.

  In the ASV plan that develops ASV, in order to enable vehicles to collect information, process information, and control vehicles based on these, information such as traffic environment around the vehicle, road surface conditions, etc., is used for various sensors and information communication devices. It is necessary to develop an infrastructure that supports safe driving based on the collected information.

  In addition, when a vehicle accident occurs, the transmission of the accident occurrence is automatically performed, so that it is expected that the accident damage due to the secondary accident can be expanded and the influence on other vehicles can be reduced.

  In general, vehicle accidents are communicated by a wireless telephone device such as a mobile phone, but neither the accident party has a mobile phone, or both accident persons are injured. May not be able to contact you.

  In addition, in order to transmit the occurrence of a vehicle accident, information on the occurrence of the vehicle accident and information on the parties involved in the vehicle accident are required, and in addition, information on the accident such as information on the location of the accident and information on the time of occurrence of the accident is required.

  On the other hand, if one of the persons involved in a vehicle accident escapes from the scene, so-called hit-and-run or breach of the duty of notification, the escape vehicle and the escape driver cannot be identified, and accurate vehicle accident transmission becomes difficult. Is expected.

  In addition, if the party of one vehicle is absent from the site due to parking or other reasons, and the other party leaves without notifying the accident, it is difficult to identify the other vehicle and driver who left. It is also expected that.

  For this reason, when a vehicle accident or the like occurs, there has already been proposed a system having a configuration for automatically reporting a vehicle accident to the police or a vehicle fire to a fire department. This system is shown in FIG. In the conventional system for reporting an accident or the like, when a vehicle accident or a vehicle fire is detected by the accident sensor 61 and the control device 62 such as an impact sensor, a temperature sensor, etc., it is automatically performed by a radio telephone 63 for an automobile mounted on the automobile 60. The vehicle accident detection signal is automatically transmitted from the antenna 64 to the police signal receiving facility, and the vehicle fire detection signal is automatically transmitted to the fire signal receiving facility.

  Further, a system shown in FIG. 9 is proposed as a system capable of transmitting an accident signal as long as the vehicle is not completely destroyed even if the antenna is damaged due to an accident or fire. That is, as shown in FIG. 9, in this system, antennas 71 and 72 are installed in the front window and the rear window of the vehicle 70, respectively, and the operating state of these antennas is monitored by the level monitoring device 73.

  In this system, when the vehicle encounters an accident and the level monitoring device 73 detects that one of the antennas 71 and 72 is damaged and not operating, the antennas 71 and 72 used by the switching device 74 are The vehicle accident information detected by the switching and impact sensor 75 and the control device 76 is automatically transmitted to the base station by the vehicle radio telephone 79 together with the vehicle specific information 77 and the vehicle position information detected by the position detection device 78. Is.

Hereinafter, a typical configuration of a vehicle accident information transmission device according to the present invention will be described with reference to the drawings. FIG. 1 is a block configuration diagram showing a system configuration including a vehicle accident information transmission device, and FIG. 2 is a block configuration diagram showing a configuration of the vehicle accident information transmission device.
The vehicle accident information transmission device 1 is mounted on its own vehicle (own vehicle) A and another's vehicle (other vehicle) B, and acquires position information of each vehicle A, B via the positioning satellite C, Moreover, it is comprised so that the time information from the long wave band standard radio wave facility D may be acquired.

  The vehicle accident information transmission device 1 includes a control means 2 for controlling each means, a transmission means 3 for transmitting each information, a receiving means 4 for receiving each information from another vehicle, and an IC card 10. An IC card read / write means 5 for reading and writing and an accident detection sensor 6 for detecting an accident are provided.

  In addition, the vehicle accident information transmission apparatus 1 includes a positioning means (vehicle accident occurrence location specifying means) 8 for specifying the current position of the vehicle A by GPS radio waves from the positioning satellite C, and a time counting for measuring time. Means (time measuring means) 7, display means 9 for displaying a road map, video for performing road guidance, and the like, and external storage means 11 for storing each information received by the receiving means 4 are provided.

  The vehicle accident information transmission device 1 may include a storage unit such as a hard disk. Here, the vehicle accident information transmission device 1 stores the vehicle specific information storage unit 10a for storing the vehicle specific information, and the vehicle for storing the vehicle accident information. A description will be given assuming that the IC card 10 includes the accident information storage unit 10b and the other vehicle accident information storage unit 10c that stores the other vehicle accident information that is the accident information of the other vehicle received via the receiving unit 4.

  When an accident of the own vehicle occurs, the transmission means 3 is controlled by the control means 2 through the antenna 3a, and the own vehicle unique information in the own vehicle unique information storage means 10a and the own vehicle accident information storage means 10b. This is for transmitting vehicle accident information without going through a base station (wireless transmission means). This transmission means 3 uses here what can be used without a license, such as MCA radio, simple radio, amateur radio, general-use radio, etc., so as to have a frequency and an output of 1 km. Yes. Moreover, as an example, it is a 27.12 MHz short-wave transmitter that has a reach of 200 to 500 meters and can be used without a license, and is digitized together with own vehicle specific information and stored in a predetermined packet. The vehicle accident information is transmitted via the antenna 3a. It goes without saying that other radio bands can be used.

  In addition, since there are many users of radio waves in the band that can be used without a license and they are not controlled by the base station, multiple radio waves are transmitted simultaneously on the same channel. When the wireless communication channel assigned to the information transmission device 1 is one channel, congestion occurs in which information from a plurality of accident parties concentrates on one channel, and both vehicles and vehicles passing nearby In some cases, information cannot be transmitted correctly.

  As a countermeasure, a plurality of communication channels are provided, and information from the perpetrator's vehicle and information from the victim's vehicle do not collide with each other using an appropriate transmission protocol such as N times of transmission at random. It is preferable that information can be transmitted correctly.

  Further, as shown in FIG. 3, a frequency division multiple access (FDMA) system that provides a communication channel on the frequency axis is taken as an example, and a, b, c, d,..., S, t , U, v 20 radio channels are used. In addition, a time division multiple access (TDMA) system or a code division multiple access (CDMA) system can be used.

  The receiving means 4 uses the antenna 3a for other vehicle specific information and other vehicle accident information transmitted from the other vehicle B without going through the base station when the other vehicle B has an accident. It is what receives (wireless receiving means). The receiving means 4 may be configured as a radio unit integrated with the transmitting means 3 already described, and the received other vehicle specific information and other vehicle accident information are controlled by the IC card read / write means 5. Output via means 2.

  The IC card read / write means 5 writes and reads each storage means 10a, 10b, 10c of the IC card 10. The IC card read / write means 5 reads and writes to the own vehicle accident information storage means 10b of the IC card 10 and the other vehicle accident information storage means 10c that stores the other vehicle accident information received via the receiving means 4, The own vehicle unique information in the own vehicle unique information storage means 10 a and the own vehicle accident information in the own vehicle accident information storage means 10 b are read and output to the transmission means 3. The IC card 10 used for the IC card read / write means 5 includes, for example, information described in the driver's license and own vehicle specific information that can identify the vehicle on which the IC card read / write means 5 is mounted. (Owner information, body number information, etc.) is stored in the own vehicle specific information storage means 10a.

  The accident detection sensor 6 is a sensor that detects an impact generated in the vehicle A and outputs the detected impact to the control means 2 as a numerical value or signal. The accident detection sensor 6 can be used as long as it can detect vibration, volume, acceleration of a vehicle body, etc. generated by an impact, such as a vibration sensor, a volume sensor, and an acceleration sensor, and also a TV camera. It can also be used. This accident detection sensor 6 and the determination unit 2a of the control means 2 described later constitute an accident detection means. Further, as shown in FIG. 4, a plurality of accident detection sensors 6 may be arranged on the front bonnet side of the host vehicle A, the rear trunk side, and the left and right side surfaces of the vehicle body. A signal detected by the accident detection sensor 6 is output to the control means 2.

  The time counting means 7 measures the time. Here, the time at which the vehicle A is driven using the long wave standard radio wave, the time when the vehicle A accident occurs, or the time from the other vehicle B is received. The received time is counted. The time measuring means 7 can use time information of a positioning satellite such as GPS, which is originally a clock, in addition to using a long wave standard radio wave. Further, it may be a general clock that can output the time as a signal.

  Here, the positioning means 8 receives GPS radio waves transmitted from the positioning satellite C and identifies the current location. This positioning means 8 is operated by the United States as a GPS, which is a representative satellite positioning system, for the positioning satellite C to be transmitted. In addition, a GLONASS (GLObal NAvigation Satellite System) satellite system operated by Russia and the European Community The GALILEO satellite system planned at the center and the satellite positioning system such as the quasi-zenith satellite system proposed by Japan can be used. The radio wave emitted from the positioning satellite C is an SHF band radio wave, and may not be received in the building shadow or in the tunnel. However, the piezoelectric gyroscope and the vehicle speed sensor are used in the building shadow and in the tunnel. Using interpolated data for positioning is advantageous because the unreceivable state is resolved.

  The display means 9 combines the position information of the current location of the vehicle A received by the positioning means 8 with the map information, displays the time information measured by the time measuring means 7, and further receives the receiving means. The other vehicle accident information received by 4 and the other vehicle accident position information where the accident occurred are displayed as characters or images combined with map information. For example, as shown in FIG. 5, the display unit 9 displays map information for guiding a destination using a navigation function, in an area on the displayed map. When other vehicle accident information is received, the driver can be alerted to the accident by displaying the accident position together with the position of the vehicle A on the map. Moreover, the display means 9 can also display each information not only as map information and character information but as a sound.

  The external storage unit 11 stores information stored in the IC card 10 almost simultaneously, and is a storage unit such as a general hard disk. The external storage means 11 is preferably arranged at a position away from the position of the IC card read / write means 5 (for example, the rear seat side when the IC card read / write means is located on the instrument panel). The external storage means 11 similarly stores information stored in the own vehicle specific information storage means 10a, the own vehicle accident information storage means 10b, and the other vehicle accident information storage means 10c.

  The control means 2 has a memory such as a flash memory, and determines whether or not an accident has occurred in the vehicle by comparing the signal from the accident detection sensor 6 with a preset threshold value; Accident information creation unit 2h that creates accident information based on a notification (judgment result) from the determination unit 2a, a transmission / reception control unit 2b that controls the transmission unit 3 and the reception unit 4, and an IC card that controls the IC card read / write unit 5 An operation unit 2c, a time control unit 2d for controlling the time measuring unit 7, a positioning control unit 2e for controlling the positioning unit 8, a display control unit 2f for controlling the display unit 9, and a storage control for controlling the external storage unit Part 2g.

  In the determination unit 2a, a threshold value is input and set in advance from an input unit (not shown) in the memory, and the signal from the accident detection sensor 6 is compared with the threshold value. The information creation unit 2h is notified. The determination unit 2a can set the threshold value to be set in stages, and by dividing the magnitude of the impact (vibration, volume, acceleration) into, for example, three stages, the scale of the accident can be set at that stage. The accident information creation unit 2h may be notified in response to a specific threshold value. In addition, the signal specified as the accident of the own vehicle output from the determination part 2a is notified to the accident information preparation part 2h.

  Upon receipt of the notification (determination result) from the determination unit 2a, the accident information generation unit 2h generates own vehicle accident information based on a preset template and notifies the IC card operation unit 2c. Here, the accident information creation unit 2h creates the vehicle accident information by acquiring the time and position at which the accident occurred from the time measuring means 7 and the positioning means 8 and writing them in a preset template. Yes. The vehicle accident information created by the accident information creation unit 2h is also notified to the display control unit 2f and the storage control unit 2g. This is because when the IC card 10 is not inserted, it is displayed on the display means 9 and is also stored in the external storage means 11.

  The transmission / reception control unit 2 b controls the transmission unit 3 and the reception unit 4. When the vehicle accident information and the vehicle accident information are output by the IC card operation unit 2c through the IC card read / write unit 5, the transmission / reception control unit 2b controls the transmission unit 3 to transmit the information to the outside. When the other vehicle unique information and the other vehicle accident information are received by the receiving means 4, the IC card operation unit 2c, the display control unit 2f, and the storage control unit 2g are also notified.

  The IC card operation unit 2 c controls the IC card read / write unit 5. Upon receiving the notification from the accident information creation unit 2h, the IC card operation unit 2c operates (controls) the IC card read / write unit 5 and stores the vehicle accident information in the vehicle accident information storage unit 10b of the IC card 10. The own vehicle accident information and the own vehicle specific information stored in the own vehicle specific information storage unit 10a are read out and notified to the transmission / reception control unit 2b. At the same time, when the IC card operation unit 2c receives the accident information (other vehicle accident information) of the other vehicle and the other vehicle specific information from the receiving means 4, the IC card read / write is notified by the transmission / reception control unit 2b. The other vehicle accident information and the other vehicle specific information are stored in the other vehicle accident information storage unit 10c of the IC card 10 by operating (controlling) the means 5.

  The time control unit 2d controls the time measuring means 7 to acquire time information. When the vehicle accident information is notified from the determination unit 2a, or when the other vehicle accident information is received by the receiving means 4 and notified from the transmission / reception control unit 2b, the timing control unit 2d measures each time. Then, the accident information creating unit 2h is notified and the display control unit 2f and the storage control unit 2g are notified.

  The positioning control unit 2e controls the positioning means 8 to acquire positioning information. When displaying the map information on the display means 9, the positioning control unit 2e obtains the position of the vehicle A from the GPS radio wave as the position information and notifies the display control unit 2f. When vehicle accident information is output and when the receiving means 4 receives other vehicle accident information, position information for controlling the positioning means 8 to identify the position of the own vehicle or the other vehicle that caused the accident is provided. Acquire and notify the IC card operation unit 2c and the display control unit 2f.

The display control unit 2 f controls the display unit 9. The display control unit 2f displays each information on the display means 9 in response to notifications from the transmission / reception control unit 2b, the IC card operation unit 2c, the timing control unit 2d, the positioning control unit 2e, and the like.
The storage control unit 2 g controls the external storage unit 11. The storage control unit 2g stores each information in the external storage unit 11 when notified from the transmission / reception control unit 2b and the IC card operation unit 2c.
Note that the vehicle accident information transmission device 1 is configured to be directly connected to a vehicle battery so that transmission and reception of each information is always performed so as to automatically operate. Any configuration that is connected to a portable rechargeable battery is convenient.

  Next, an outline of the operation of the vehicle accident information transmission device 1 will be described. FIG. 6 is a plan view showing a case where an accident occurs between vehicles equipped with a vehicle accident information transmission device, and FIG. 7 is a flowchart showing the operation of the vehicle accident information transmission device 1. The configuration of the vehicle accident information transmission device 1 will be described with reference to FIG. 2, and the operation will be described with reference to FIG. Further, “S” in FIG. 7 is indicated as “step”.

  The driver who drives the vehicle A, for example, displays the map information on the display means 9 while driving the vehicle A and travels to the destination using the navigation. As shown, a case where an accident occurs due to a collision with another vehicle B from behind and a third-party vehicle AD is traveling in the same lane and oncoming lane at the location where the accident occurred will be described. The own vehicle A, the other vehicle B, and the third party vehicle AD are operating with the vehicle accident information transmission device 1 turned on and the IC card 10 inserted in the IC card read / write means 5. Shall.

As shown in FIG. 6, when another vehicle B of the following vehicle collides for some reason during traveling of the own vehicle A, the own vehicle A has an accident detection sensor of the vehicle accident information transmission device 1 as shown in FIG. 2. 6 detects (detects) an impact, and outputs a signal corresponding to the magnitude of the detected impact to the control means 2.
As shown in FIG. 7, the determination unit 2a of the control means 2 compares the signal output from the accident detection sensor 6 with a preset threshold value, and determines whether or not the threshold value is exceeded (step 1). .

  When the vehicle accident information transmission apparatus 1 determines that the output signal exceeds the threshold by the determination unit 2a of the control means 2, the accident information creation unit 2h, the time measurement control unit 2d, and the positioning control unit 2e The notified accident information creation unit 2h acquires time measurement time information and positioning information, creates own vehicle accident information (step 2), and notifies the IC card operation unit 2c. Further, the vehicle accident information transmission device 1 operates the IC card read / write means 5 via the IC card operation unit 2 c and stores the created own vehicle accident information in the own vehicle accident information storage means 10 b of the IC card 10. (Step 3).

Further, when the vehicle accident information transmission device 1 stores the vehicle accident information in the vehicle accident information storage unit 10b of the IC card 10, the IC card operation unit 2c is stored in the vehicle specific information storage unit 10a. Along with the vehicle-specific information, the vehicle accident information is read from the vehicle accident information storage unit 10b, notified to the transmission / reception control unit 2b, the display control unit 2f, and the storage control unit 2g, and the transmission unit 3 is transmitted by the transmission / reception control unit 2b. The vehicle specific information and the vehicle accident information are transmitted to the outside without going through the base station (step 4).
The vehicle accident information transmission device 1 that has transmitted the own vehicle unique information and the own vehicle accident information simultaneously displays the own vehicle unique information and the own vehicle accident information on the display means 9 (step 5) and stores them in the external storage means 11. .

Similarly, in the other vehicle B, the same operation is performed, and the other vehicle specific information and the other vehicle accident information are transmitted from the other vehicle B without passing through the base station, and the transmitted other vehicle specific information and other information are transmitted. The vehicle accident information transmission device 1 determines whether the vehicle accident information has been received via the receiving means 4 (step 6).
The vehicle accident information transmission device 1 uses the transmission / reception control unit 2b of the control unit 2 to transmit the other vehicle specific information and the other vehicle accident information received by the receiving unit 4 to the IC card operation unit 2c, the display control unit 2f, and the storage control unit 2g. And the other vehicle specific information and the other vehicle accident information are stored in the other vehicle accident information storage unit 10c of the IC card 10 via the IC card read / write unit 5 by the IC card operation unit 2c (step 7).
At the same time, the vehicle accident information transmission device 1 displays the other vehicle specific information and the other vehicle accident information on the display means 9 (step 5), and stores them in the external storage means 11.

  In this way, when an accident occurs, the own vehicle A transmits the unique information of the own vehicle and the accident information to the other party, and receives the other vehicle unique information and the other vehicle accident information from the other vehicle B. It becomes possible to identify the party of the accident. Further, in the third party vehicle AD, each information from the own vehicle A and the other vehicle B will be received as other vehicle specific information and other vehicle accident information. In the third party vehicle AD, as shown in FIG. The operations of Step 6, Step 7 and Step 5 are performed.

  Since these operations are automatically performed and accident information is stored in other vehicles, accident information is ensured even in the case of a serious accident that causes the driver to die. Also, if one of the accident parties escapes from the scene, or if one of the vehicle parties is absent from the scene and the other party leaves without notifying the accident, the vehicle-specific information and the accident information are automatically Since it is transmitted and stored without going through the station, it is possible to easily identify the vehicle of the accident party who has left.

  If the vehicle accident information is stored not only for the party of the accident but also for other vehicles that happened to be near, the vehicle accident information is effective as witness information when the responsibility for the vehicle accident becomes a problem. In this case, if the witness is also witnessed and the unique information of the witness is transmitted corresponding to the received accident information, it becomes easy to search for the witness. Furthermore, if the specified vehicle accident occurrence time information is used, the location information and the time information specified by the common base exist, so that the situation of the accident can be surely grasped in the case of actual inspection.
