Description

  The present invention relates to a technique for detecting the occurrence of an earthquake and notifying a driver during operation of the detected occurrence of an earthquake.

  Since a traveling vehicle constantly vibrates due to its traveling, it is difficult to apply a commonly used earthquake detection device for in-vehicle use, and a driver cannot take an appropriate response when an earthquake occurs. Although the seismic intensity varies greatly depending on the ground, the location of seismometers is limited and it is difficult to predict local damage.

  For example, the travel control device disclosed in Patent Document 1 discloses a configuration in which a travel plan for decelerating and stopping the vehicle based on the received emergency earthquake warning is generated and the travel of the vehicle is controlled. However, as described in Patent Document 1, the earthquake early warning detects an earthquake P wave having a high transmission speed and distributes it to a corresponding area before arrival of an S wave having a low transmission speed and a large shaking. However, there is a problem that it is not possible to promptly notify the occurrence of an earthquake in a direct type earthquake with a close epicenter.

  As of October 2009, the number of observation points used for seismic intensity information announced by the Japan Meteorological Agency is about 4200, and it cannot be used when the seismic intensity varies locally depending on the ground in locations where no observation points exist. Therefore, the emergency earthquake warning system disclosed in Patent Document 2 discloses a configuration that effectively obtains earthquake observation information by combining information of seismometers installed in the private sector and emergency earthquake warning.

On the other hand, in-vehicle navigation systems, in-vehicle antitheft devices and the like have become widespread in recent years. For example, in the navigation server disclosed in Patent Document 3, a configuration is disclosed in which the position of the host vehicle is transmitted to the server, roads that are accessible on the server side are searched, and road information is provided.
Further, the vehicle antitheft system disclosed in Patent Document 4 discloses a configuration that detects vibration of the host vehicle and provides information to the driver by e-mail or the like when there is a risk of theft.

In the technique disclosed in Patent Document 2 described above, there is a cost for installing a seismometer in a place where an observation point does not exist, and the place where the seismometer is installed is limited to places where there are many people such as schools and factories. There was a problem that the spread of the system was limited.
Moreover, although it is possible to detect an earthquake by using the navigation system and anti-theft device which are the techniques disclosed in Patent Document 3 and Patent Document 4, these are applied to a moving body in which vibration is constantly generated by traveling. The navigation system and anti-theft device were installed, and it was difficult to function as an earthquake detection device.

  The present invention has been made to solve the above-described problems, and detects the occurrence of earthquakes at more points and immediately notifies the driver of the moving vehicle of the occurrence of the earthquake. Objective.

Embodiment 1 FIG.
1 is a block diagram showing a configuration of an earthquake detection apparatus according to Embodiment 1 of the present invention.
The earthquake detection device 10 includes a position detection unit 1, an acceleration sensor unit 2, a memory unit 3, a signal processing unit 4, a power supply control unit 5, and a communication unit 6. The signal processing unit 4 is connected to a notification unit 7 and a security control unit 8 which are external devices.
The position detection part 1 is comprised by GPS etc., and acquires the position which the own vehicle parked as the positional information which showed with the latitude and the longitude. Whether or not the host vehicle is parked is determined with reference to the position information of the shift lever provided from the host vehicle, host vehicle information such as the operating state of the engine, and the like. Further, the parking vehicle position information is acquired when +12 V is supplied to + IG while the ignition key is ON, and is stored in the memory unit 3 via the signal processing unit 4. After the position information is stored in the memory unit 3, the position detection unit 1 is turned off to reduce power consumption.

  The acceleration sensor unit 2 is composed of a sensor capable of measuring three-axis accelerations in the vertical direction, the horizontal direction, and the front-rear direction of the host vehicle. The acceleration sensor unit 2 is assumed to be energized in the standby state by the power supplied from the + B battery even when the ignition key is OFF and +12 V is not supplied to + IG. When the vibration of the vehicle, that is, the change in acceleration is detected, the signal processing unit 4 is shifted from the standby state with low power consumption to the normal state by the wake-up function, and the change in the acceleration of the own vehicle is transmitted via the signal processing unit 4. Records in the memory unit 3. It is assumed that the acceleration sensor unit 2 is always energized and that a change in acceleration can always be detected.

  The signal processing unit 4 includes a microcomputer or the like, and includes a vibration correction processing unit 4a, a waveform compression processing unit (compression processing unit) 4b, a timer processing unit 4c, and a theft / earthquake determination processing unit (determination unit) 4d. In the configuration example of FIG. 1, the configuration in which the memory unit 3 is provided outside the signal processing unit 4 is shown. However, the memory unit 3 may be built in the signal processing unit 4. The same applies to other embodiments described below.

  The vibration correction processing unit 4a uses the acceleration information recorded in the memory unit 3 as a change in the acceleration of the host vehicle to perform a process of correcting the vibration according to the damping force generated by the suspension that differs for each vehicle type. Vibration attenuation due to damping force varies depending on the direction in which the acceleration is applied. Therefore, the longitudinal or lateral acceleration of the host vehicle is corrected to change in the north-south or east-west acceleration depending on the direction when the host vehicle is parked. . Further, the vibration correction processing unit 4a performs a process of correcting a change in the vertical acceleration of the host vehicle because the vertical acceleration of the host vehicle is greatly attenuated by the deformation of the suspension and the tire. It is assumed that the vibration correction processing unit 4a has a correction amount for each vehicle type as a database or can be acquired from the outside via the communication unit 6.

The timer processing unit 4c is a timer that measures a certain time after the host vehicle is parked. This prevents vibrations that occur when an occupant gets off immediately after parking the vehicle, or vibrations that occur when a parking pallet moves when parked in a mechanical parking lot, as vibrations caused by earthquakes. Because.
The signal processing unit 4 refers to the measurement time of the timer processing unit 4c and determines that the vehicle is parked in the self-propelled parking lot when the vibration stops relatively shortly after parking the host vehicle and no vibration occurs thereafter. The signal detected after the elapse of a certain time is recorded as vibration and transmission of the recorded vibration information because there is a possibility of vibration due to an earthquake. On the other hand, if the vehicle generates multiple vibrations within a certain period of time, it is determined that the vehicle is parked in a place that is not suitable for detecting vibrations such as a mechanical parking lot or a two-story parking lot with a lot of vibration. Even if the vibration is detected after a certain time has elapsed, the vibration is not recorded and the vibration information is not transmitted.

  The theft / earthquake determination processing unit 4d receives vehicle information including vibration information transmitted from an earthquake detection device mounted on another vehicle via the communication unit 6, and whether the vibration is caused by an earthquake based on the reception status. Determine whether the vibration is caused by theft. Specifically, when vehicle information including vibration information is transmitted from a plurality of parked vehicles located in the same area within a predetermined position range at the same time or within a predetermined time, it is determined that the vibration is caused by an earthquake. When vehicle information including vibration information is transmitted only from a single vehicle, it is determined that the vehicle may be stolen.

  The power supply control unit 5 determines the state of the ignition key based on whether or not 12V is supplied to + IG. When the ignition key is in the ON state, it is necessary for normal operation for all the internal components of the earthquake detection device 10. Supply the power to become. When the ignition key shifts to the OFF state after the host vehicle is parked, the internal components are energized for a predetermined time in accordance with the measurement time of the timer processing unit 4c of the signal processing unit 4 to detect the position. The unit 1 acquires position information, and the acceleration sensor unit 2 executes acceleration measurement. After a certain period of time has elapsed, a transition is made to a standby power mode that suppresses energization of each internal configuration, thereby reducing power consumption.

  When vibration is detected in the acceleration sensor unit 2 after a predetermined time has elapsed and in the standby power mode, the signal processing unit 4 is activated by the wake-up function of the acceleration sensor unit 2 and communicated by the power control signal of the power control unit 5 Power supply to the unit 6 is started. Thereby, while suppressing the power consumption of the earthquake detection apparatus 10 mounted in the parked vehicle to the minimum, when vibration is detected, the vibration information can be promptly transmitted to another vehicle. To control.

  The communication unit 6 uses the vibration information processed by the signal processing unit 4, the position information of the vehicle detected by the position detection unit 1, the vehicle type of the own vehicle, the vehicle-specific ID, and the like as vehicle information, as an earthquake detection device for other vehicles. And send it to the server. Moreover, the communication part 6 receives vehicle information etc. from the earthquake detection apparatus of another vehicle, or a server. As a communication method of the communication unit 6, for example, a method of communicating with a server via a base station like a communication method of a mobile phone, or a vehicle located around the host vehicle like a vehicle-to-vehicle communication A method or the like can be applied. Note that it is only necessary to establish communication with an earthquake detection device or a server of another vehicle, and any communication method is not particularly limited.

  The notification unit 7 includes a display having a display function, a speaker having a sound output function, and the like, and notifies the driver of the occurrence of an earthquake by text, video, or sound. Although the configuration provided outside the earthquake detection device 10 is shown in FIG. 1, it may be built in the earthquake detection device 10. The same applies to other embodiments described below.

  The security control unit 8 is configured by a door lock of the host vehicle, an immobilizer that does not start the engine other than normal unlocking, and controls the security of the host vehicle. When the host vehicle is parked, it is detected whether or not the locking or unlocking has been normally performed, and the signal processing unit 4 is notified. In the signal processing unit 4, when detection information indicating that the unlocking has been performed illegally is input, if vibration is detected because the risk of theft is high, the vibration is different from normal unlocking or vibration caused by the occupant's boarding. Vibration information indicating vibration is generated and transmitted via the communication unit 6. On the other hand, when detection information indicating that the unlocking has been normally performed is input, the signal processing unit 4 determines that the vibration is generated when the occupant gets on, and generates or transmits vibration information for a certain period of time after unlocking. do not do.

FIG. 2 is a diagram showing the configuration of a vehicle-to-vehicle earthquake detection system using the earthquake detection device according to Embodiment 1 of the present invention.
As shown in FIG. 2, in this Embodiment 1, the earthquake detection system which communicates information directly between vehicles without going through a server is constructed | assembled. In order to construct an earthquake detection system that does not use a server, the signal processing unit 4 of the earthquake detection device 10 mounted on each vehicle needs to include a theft / earthquake determination processing unit 4d.
Vehicles 100a, 100b, and 100c are parked vehicles, and are equipped with earthquake detection devices 10a, 10b, and 10c, respectively. Further, the vehicle 100d is a traveling vehicle, and similarly, the earthquake detection device 10d is mounted. It is assumed that the earthquake detection device 10d is located at a distance that allows direct communication with each of the earthquake detection devices 10a, 10b, and 10c.

  When an earthquake occurs, the earthquake detection devices 10a, 10b, 10c of the vehicles 100a, 100b, 100c are activated and transmit vehicle information including vibration information. The transmitted vehicle information is received by the earthquake detection device 10d of the vehicle 100d. When the earthquake detection device 10d receives vehicle information from the vehicles 100a, 100b, 100c at the same time or within a predetermined time, the theft / earthquake determination processing unit 4d determines that an earthquake has occurred, and the driver of the vehicle 10d Is notified of the occurrence of an earthquake. On the other hand, when the earthquake detection device 10d receives vehicle information from only one vehicle, the theft / earthquake determination processing unit 4d determines that the vehicle vibrates due to a factor other than the earthquake such as theft or hit-and-run. Thus, the driver of the vehicle 10d is not notified.

Next, operation | movement of the earthquake detection apparatus 10 is demonstrated in detail, referring the flowchart of FIG. 3 and FIG. The description will be divided into a process for generating vehicle information including vibration information when the host vehicle is parked, and a process for receiving vehicle information including vibration information while the host vehicle is traveling. .
First, the processing operation for generating vehicle information will be described with reference to FIG.
(1) Generation processing of vehicle information including vibration information In this vehicle information generation processing, the description will be made assuming that the host vehicle on which the map detection device 10 is mounted is parked in a place where vibration due to an earthquake can be measured.
When parking of the host vehicle is detected, the timer processing unit 4c starts measuring time from the start of parking (step ST1), and the position detecting unit 1 acquires position information indicating the parking spot of the host vehicle by latitude and longitude. Then, it is recorded in the memory unit 3 via the signal processing unit 4 (step ST2). The acceleration sensor unit 2 determines whether or not a change in acceleration with respect to the host vehicle is detected (step ST3). If no change in acceleration is detected (step ST3; NO), the determination process of step ST3 is continued. On the other hand, when a change in acceleration is detected (step ST3; YES), the acceleration sensor unit 2 shifts the signal processing unit 4 from the standby state to the normal state by the wake-up function (step ST4), and is detected in step ST3. Acceleration information indicating the change in acceleration is recorded in the memory unit 3 via the signal processing unit 4 (step ST5).

  The vibration correction processing unit 4a of the signal processing unit 4 that has shifted to the normal state in step ST4 acquires acceleration information recorded in the memory unit 3, and corrects attenuation of vibrations in the front-rear direction, the left-right direction, and the vertical direction of the vehicle. (Step ST6). The waveform compression processing unit 4b performs waveform compression of the vibration corrected in step ST6, and generates vibration information (step ST7). The signal processor 4 refers to the elapsed time at which measurement was started in step ST1 and determines whether or not a certain time has elapsed (step ST8). If the predetermined time has not elapsed (step ST8; NO), the signal processing unit 4 determines that the vibration information generated in step ST7 is not due to earthquake vibration, returns to the process of step ST3, and performs the process described above. repeat.

  On the other hand, when the predetermined time has elapsed (step ST8; YES), the signal processing unit 4 determines that the vibration information generated in step ST7 is due to earthquake vibration, and outputs the information to the communication unit 6 (step). ST9). The communication unit 6 transmits the vibration information input in step ST9, the position information acquired in step ST2, and the vehicle type and vehicle unique ID of the host vehicle as vehicle information to the earthquake detection device of the other vehicle ( Step ST10). Thereafter, the flow returns to the process of step ST3 and repeats the above-described process.

Next, processing operations when vehicle information including vibration information is received will be described with reference to FIG.
(2) Reception processing of vehicle information including vibration information When the theft / earthquake determination processing unit 4d of the signal processing unit 4 receives the vehicle information via the communication unit 6 (step ST11), a plurality of receptions are performed at the same time or within a predetermined time. It is determined whether or not vehicle information including information that vibration has occurred in another vehicle has been received (step ST12). When vehicle information including information that vibrations have occurred in a plurality of other vehicles at the same time or within a predetermined time is received (step ST12; YES), it is determined that an earthquake has occurred (step ST13), and the notification unit 7 is used. The occurrence of an earthquake is notified to the passenger of the own vehicle (step ST14).

  On the other hand, when vehicle information including information that vibration has occurred in only one other vehicle is received (step ST12; NO), it is determined that there is a risk of theft (step ST15), and notification to the passenger of the own vehicle is Not performed. After step ST14 and step ST15, the flow returns to the process of step ST11 and repeats the process described above.

  As described above, according to the first embodiment, when vibration caused by an earthquake is detected in the earthquake detection device 10 mounted on a parked vehicle, the earthquake detection device 10 mounted on another traveling vehicle is detected. Because it is configured to transmit vehicle information including vibration information, it is possible to detect the vibrations caused by earthquakes and the intensity of earthquake shaking at many points, and immediately notify the driver of the vehicle that is running can do. Thereby, it is possible to appropriately notify the driver of the occurrence of an earthquake even in a region where a direct earthquake occurs or in a place where shaking is locally large due to the ground. In addition, since detailed seismic intensity information can be obtained over a wide area, it can be used for quick estimation of damage after an earthquake occurs.

  In addition, according to the first embodiment, the acceleration sensor unit 2 having a wake-up function is provided, and when the acceleration sensor unit 2 detects a change in acceleration, the signal processing unit 4 is activated to obtain acceleration information and vibration information. Since the earthquake detection device 10 suppresses the power consumption of the earthquake detection device 10 mounted on the parked vehicle to the minimum, the vehicle information including the vibration information is generated by appropriately detecting the vibration. can do.

  In addition, according to the first embodiment, the vibration correction processing unit 4a for correcting the vibration is provided in consideration of the damping force generated by the suspension different for each vehicle type. Even in a vehicle in which vibration is not directly transmitted to the vehicle body, it is possible to appropriately detect earthquake vibration.

The vibration correction processing unit 31 uses the vibration information transmitted from each of the earthquake detection devices 10a ′, 10b ′, and 10c ′ to perform a process of correcting the vibration according to the damping force generated by the suspension that is different for each vehicle type. The theft / earthquake determination processing unit 32 determines based on the vibration information corrected by the vibration correction processing unit 31 whether an earthquake has occurred or whether the vehicle alone may be stolen. If vehicle information including information on the occurrence of vibration in a plurality of vehicles located in the same area within a predetermined position range is transmitted at approximately the same time or within a predetermined time, it is determined that an earthquake has occurred, and one When vehicle information including information that vibration has occurred only in the vehicle is transmitted, and when a normal unlocking operation is not performed, it is determined that there is a risk of theft.

In the following, the same or corresponding parts as those of the earthquake detection apparatus 10 shown in FIG. 1 are denoted by the same reference numerals as those used in FIG. 1 and the description thereof is omitted or simplified. Moreover, the earthquake detection apparatus 10 ′ ″ ″ having the mobile terminal function shown in FIG. 10 shows a configuration assuming a case where information is directly communicated between vehicles without using a server.

  The position detection unit 1 ′ is configured by a GPS or the like, and acquires own vehicle position information necessary for generating navigation information. Moreover, the positional information which showed the position where the own vehicle parked with the latitude and the longitude is acquired from the acquired own vehicle position information. The position information is acquired when the earthquake detection device 10 ″ ″ ″ receives power supply from the vehicle side and the navigation processing unit 4 e configured by the navigation application is activated, and is recorded in the memory unit 3. . The acceleration sensor unit 2 ′ detects acceleration applied to the own vehicle and also detects acceleration applied to the earthquake detection device 10 ″ ″ ′ having a mobile terminal function.

  The navigation processing unit 4e of the signal processing unit 4 ′ ″ is a configuration that realizes an existing navigation function, and operates as a navigation application in the mobile terminal. The use location determination processing unit 4f refers to the acceleration applied to the own vehicle detected by the acceleration sensor unit 2 ′ and the acceleration applied to the earthquake detection device having the mobile terminal function, and the earthquake detection device 10 having the mobile terminal function. ″ ″ ″ Is in a state where it is mounted on the vehicle, is in a state where the owner is carrying it in a pocket or back, or is placed at a predetermined position such as a table at home. A process of determining whether the state is present is performed.

  Whether the vehicle is mounted on the vehicle is determined by the acceleration / deceleration of the vehicle being connected to a device on the vehicle side or being subject to acceleration caused by vibration in the vertical direction with respect to the vehicle as vibration during traveling of the vehicle. This can be determined from the situation in which longitudinal acceleration is applied to the vehicle due to deceleration. In this case, the use place is assumed to be mounted on the vehicle. In the case where the vehicle is connected to a device on the vehicle side, the determination that the vehicle is mounted is held even when the generation of vibration is stopped because the vehicle is parked.

  On the other hand, whether the owner is carrying or not is determined if the owner of the earthquake detection device 10 ′ ″ ″ having a mobile terminal function is accelerated in the rotational direction. It is determined that the mobile phone is being carried and the place of use is carried. Also, if there is no change in acceleration from the state of carrying and the time when there is almost no change in acceleration continues for a long time, it is in a state of being charged with the AC adapter or being placed in a predetermined place Judgment is made and the place of use is charging / leaving.

  The signal processing unit 4 ″ ″ performs different processes depending on the usage location determined by the usage location determination processing unit 4 f. In addition, when the earthquake detection apparatus 10 ′ ″ ″ having the mobile terminal function determines that the mobile terminal function is being carried, vibration information for earthquake detection is not acquired. First, the vibration correction processing unit 4a vibrates according to the damping force generated by the suspension different for each vehicle type only when the earthquake detection device 10 ′ ″ ″ having the mobile terminal function is determined to be mounted on the vehicle. Perform correction processing. If it is determined that charging / leaving is being performed, vibration correction is not performed. The waveform compression processing unit 4b compresses the amount of information by performing waveform compression on the vibration detected while the earthquake detection device 10 ′ ″ ″ having the mobile terminal function is mounted on the vehicle and charging / leaving, and transmits the information. Various methods can be applied to reduce the data.

  When it is determined that the earthquake detection device 10 ″ ″ ″ having the mobile terminal function is being mounted on the vehicle, the timer processing unit 4 c measures a certain time after the host vehicle starts parking. By referring to the measurement time of the timer processing unit 4c, the signal processing unit 4 '' 'is a parking pallet when the occupant gets out of the vehicle immediately after parking the own vehicle or when parking in a mechanical parking lot. Can be prevented from being erroneously recognized as vibration caused by an earthquake. The theft / earthquake determination processing unit 4d receives vehicle information transmitted from the earthquake detection device 10 mounted on another vehicle via the communication unit 6, and is a vibration due to an earthquake or a vibration due to theft based on the reception status. It is judged whether it is.

  The power supply control unit 5 controls and manages the power supply from the vehicle and the power supply of the battery 14. When the power supply from the vehicle is stopped, it is determined as IG-OFF, and each internal configuration is energized for a predetermined period of time according to the measurement time of the timer processing unit 4c of the signal processing unit 4 ′ ″. The detection unit 1 acquires position information, and the acceleration sensor unit 2 ′ executes acceleration measurement. After a certain period of time has elapsed, a transition is made to a standby power mode that suppresses energization of each internal configuration, thereby reducing power consumption.

  When a certain amount of vibration is detected in the acceleration sensor unit 2 ′ in the standby power mode after a certain time has elapsed, the mobile terminal function includes the signal processing unit 4 ″ by the wake-up function of the acceleration sensor unit 2 ′ Start supplying power to the entire system. This minimizes the power consumption of the battery 14 when the host vehicle is parked, and promptly transmits vehicle information including the vibration information to other vehicles when vibration is detected. Control so that you can.

  The notification unit 7 ′ includes a display having a display function, a speaker having a sound output function, and the like. During normal driving of the vehicle, a display related to the navigation application by the operation of the navigation processing unit 4e is performed. Notify the driver.

  The in-vehicle audio / display 60, which is an external device, is an audio device mounted on a vehicle, and is connected to an earthquake detection device 10 ′ ″ ″ having a mobile terminal function, so that music and voice by the mobile terminal function can be obtained.

In this case, measurement of time from the start of parking is started (step ST31). The position detection unit 1 acquires position information indicating the location of use of the earthquake detection device 10 ″ ″ ″ equipped with the mobile terminal function in latitude and longitude, and records it in the memory unit 3 through the signal processing unit 4 ″ ″. (Step ST32).

  The acceleration sensor unit 2 ′ determines whether or not a change in acceleration with respect to the host vehicle is detected and whether or not a change in acceleration with respect to the earthquake detection device 10 ′ ″ ″ having the mobile terminal function is detected (step ST33). . If no change in acceleration is detected (step ST33; NO), the determination process of step ST33 is continued. On the other hand, when a change in acceleration is detected (step ST33; YES), the acceleration sensor unit 2 ′ causes the signal processing unit 4 ″ to shift from the standby state to the normal state by the wakeup function (step ST34). Acceleration information indicating the change in acceleration detected in ST33 is recorded in the memory unit 3 via the signal processing unit 4 '' '' (step ST35).

  The vibration correction processing unit 4a of the signal processing unit 4 ″ ″ transitioned to the normal state in step ST34 refers to the use location determined by the use location determination processing unit 4f, and the earthquake detection device 10 ″ having a mobile terminal function. It is determined whether or not “″ is mounted on the vehicle (step ST36). When the vehicle is being mounted (step ST36; YES), the vibration correction processing unit 4a acquires the acceleration information recorded in the memory unit 3, and corrects the vibration attenuation in the front-rear direction, the left-right direction, and the up-down direction of the vehicle ( Step ST37). The waveform compression processing unit 4b performs waveform compression of the vibration corrected in step ST37, and generates vibration information (step ST38). The signal processing unit 4 ′ ″ refers to the elapsed time when measurement was started in step ST31 and determines whether or not a certain time has elapsed (step ST39).

  When the predetermined time has not elapsed (step ST39; NO), the signal processing unit 4 ′ ″ determines that the vibration information generated in step ST38 is not due to earthquake vibration, and returns to the process of step ST33. The above processing is repeated. On the other hand, when the predetermined time has elapsed (step ST39; YES), the signal processing unit 4 ′ ″ determines that the vibration information generated in step ST38 is due to earthquake vibration and outputs it to the communication unit 6. (Step ST40).

  On the other hand, when the vehicle is not being mounted (step ST36; NO), the waveform compression processing unit 4b performs vibration waveform compression included in the acceleration information recorded in the memory unit 3 to generate vibration information (step ST41), and communication. It outputs to the part 6 (step ST42). Thereafter, the communication unit 6 uses the vibration information input in step ST40 or step ST42, the position information acquired in step ST32, the vehicle type of the host vehicle, the vehicle unique ID, and the like as vehicle information, and the earthquake detection device 10 of another vehicle. It transmits with respect to "" "" (step ST43). Thereafter, the flow returns to the process of step ST33 and repeats the above-described process.

  The earthquake detection device 10 ′ ″ ″ having a portable terminal function can be detached from the vehicle and is charged on a charger installed in a building or left on the charger. It is possible to detect vibrations caused by earthquakes and transmit them as vibration information. On the other hand, when the earthquake detection device 10 ″ ″ ″ having the mobile terminal function is left in a sofa or a bag in a state where the vibration is attenuated, it may be detected as vibration smaller than actual. In this case, if there is an earthquake detection device 10 ″ ″ ″ fixed in a state where the vibration is not attenuated in a surrounding building or the like, the vibration due to the earthquake can be accurately detected. Accurate seismic intensity can be estimated by counting information with a large vibration value or information indicating an average vibration value in the processing unit 4d.
