Description

The present disclosure relates to an emergency call device that makes an emergency call when an abnormal situation occurs.

As described in Patent Document 1, in an emergency notification device mounted on a vehicle, there is known a technique of making a call with a notification center when an emergency event occurs and transmitting an image around the vehicle to the notification center. ing. When an in-vehicle battery is abnormal when an emergency event occurs, this emergency notification device operates by a built-in backup battery to make a call with the notification center and send an image to the notification center. Then, when the remaining amount of the backup battery falls below a certain value, the transmission of the image to the notification center is prohibited.

Japanese Patent No. 6079705

However, in the emergency notification device of Patent Document 1, after the occurrence of the emergency event, both the call with the notification center and the transmission of the image are performed until the remaining amount of the backup battery falls below a certain value. As a result, the power consumption of the backup battery increases, and as a result, the time during which a call with the notification center is possible may be shortened.

The present disclosure provides technology that enables more appropriate handling of abnormal situations.

An emergency notification device (10) according to one aspect of the present disclosure is mounted on a vehicle (2), and includes a photographing unit (12), a communication control unit (11), a power supply unit (15), and a backup power supply (16). With. The photographing unit photographs the inside and/or the outside of the vehicle with the camera (13) and stores the photographed image in the storage unit (14). The communication control unit communicates with the center (3). The power supply unit supplies the electric power supplied from the vehicle-mounted battery (2a) mounted on the vehicle to the camera, the storage unit, the photographing unit, and the communication control unit. The backup power supply supplies power to at least the communication control unit when the power supply from the vehicle-mounted battery is abnormal, and at least a part of the camera, the storage unit, and the imaging unit. No power is supplied to the exclusion target. When an abnormal situation occurs in the vehicle, if the power supply is not abnormal, the communication control unit makes an emergency notification with the center to notify the abnormal situation, and reads the captured image stored in the storage unit. The information is transmitted to the center, and if the power source is abnormal, an emergency call is issued (S125 to S135).

According to the above configuration, the backup power supply used when the power supply abnormality of the vehicle-mounted battery occurs supplies power to the communication control unit, but at least a part of the camera, the storage unit, and the imaging unit. Does not supply power. Therefore, the power consumption of the backup power supply can be suppressed, and an emergency call between the center and the emergency call device can be made for a longer period when an abnormal situation occurs. Therefore, when an abnormal situation occurs, the electric power stored in the backup power supply can be more appropriately distributed, and the abnormal situation can be dealt with more appropriately.

It should be noted that the reference numerals in parentheses described in this column and the claims indicate the correspondence with the specific means described in the embodiments described below as one aspect, and limit the technical scope of the present disclosure. Not something to do.

The emergency operation device may be connected to the in-vehicle network 40, or the emergency notification device 10 or the like may be configured as an emergency operation device. When the emergency operation device receives the emergency operation, the emergency operation device transmits an emergency stop instruction of the vehicle 2 to the vehicle control device 30 via the in-vehicle network 40. By providing such an emergency operation device, the vehicle 2 can be brought to an emergency stop when a driver or an occupant notices the occurrence of an abnormal situation.

[2. Emergency call device]
Next, the emergency notification device 10 will be described in detail with reference to FIG. The emergency notification device 10 makes an emergency call to the center 3 when an abnormal situation occurs, and notifies that the abnormal situation has occurred. Further, the emergency notification device 10 periodically photographs the outside and/or the inside of the vehicle with at least one camera 13 mounted on the vehicle 2 and stores the photographed image. Then, at the time of an emergency call, the stored photographed image is transmitted to the center 3. Note that, in the first embodiment, as an example, a plurality of cameras 13 capture images.

The communication control unit 11 accesses the communication network 4 by wireless communication via the antenna 11 a and communicates with the center 3 via the communication network 4. As an example, the communication control unit 11 may access the communication network 4 for mobile phones. Further, the communication control unit 11 sends the photographed image to the center 3 while making the above-mentioned emergency notification to the center 3. Further, the communication control unit 11 receives a command for operating the emergency notification device 10 from the center 3. Further, the communication control unit 11 may provide a call function with the operator of the center 3 by using a microphone and a speaker (not shown) provided in the emergency notification device 10. Further, the communication control unit 11 may include, for example, a microcontroller including a CPU, a ROM, a RAM, etc., and a part of the function may be realized by the microcontroller.

The photographing unit 12 periodically photographs the outside and/or the inside of the vehicle with the camera 13 while the vehicle 2 is driving, and stores the photographed image data in the storage unit 14. In addition, the photographing unit 12 deletes, from the storage unit 14, the data of the photographed image after a fixed time (for example, 24 hours) has elapsed after the photographing.

The storage unit 14 is a rewritable nonvolatile storage medium. The storage unit 14 may be composed of, for example, a flash memory or the like.
The power supply unit 15 supplies the electric power supplied from the on-vehicle battery 2a mounted on the vehicle 2 to the camera 13 and each part of the emergency notification device 10, such as the communication control unit 11, the photographing unit 12, and the storage unit 14. To do.

The backup power supply 16 is a battery that supplies power in place of the vehicle-mounted battery 2a when an abnormality in power supply from the vehicle-mounted battery 2a to the emergency notification device 10 (hereinafter, power source abnormality) occurs. When the power supply from the vehicle-mounted battery 2a is normal and the power source is normal, the vehicle-mounted battery 2a may charge the backup power supply 16. The backup power supply 16 supplies power to each part of the emergency notification device 10 including the communication control unit 11 at the time of power failure, but at least a part of the camera 13, the storage unit 14, and the imaging unit 12 does not. No power is supplied.

Hereinafter, a part to which power is not supplied from the backup power supply 16 at the time of power supply abnormality is described as an exclusion target, and a part to which the power is supplied is described as a power supply target. As an example, at least the camera 13 may be excluded. More specifically, all the cameras 13 used for photographing by the photographing unit 12 may be excluded, or a part of the cameras 13 may be excluded. Further, for example, at least the storage unit 14 may be a power supply target.

[3. Configuration of power supply, etc.]
Regarding the power supply when the power supply is abnormal, for example, all of the camera 13, the storage unit 14, and the imaging unit 12 may be excluded from the power supply from the backup power supply 16. In this case, the power supply unit 15 and the like may be configured as shown in FIG.

That is, the power supply unit 15 has power supply circuits 15a to 15d, a backup power supply circuit 15e, a switch 15f, and first and second power supply lines 15g and 15h.
The power supply circuits 15a to 15d supply power to the communication control unit 11, the image capturing unit 12, the storage unit 14, and the camera 13, respectively.

Further, the first power supply line 15g supplies the power from the vehicle-mounted battery 2a to the communication control unit 11 via the power supply circuit 15a.
The second power supply line 15h is branched from the first power supply line 15g, and the power from the vehicle-mounted battery 2a is supplied to the photographing unit 12, the storage unit 14, and the camera 13 via the power supply circuits 15b to 15d. Supply to.

Further, the second power supply line 15h is provided with a switch 15f composed of a power MOSFET as an example. Then, when the switch 15f is in the ON state, power is supplied through the second power supply line 15h, and when the switch 15f is in the OFF state, power supply through the second power supply line 15h is cut off.

Further, the backup power supply circuit 15e controls the power supply from the backup power supply 16. The backup power supply circuit 15e is connected to the first power supply line 15g.
Then, when the power supply is normal, the switch 15d is turned on, and power is supplied to each part of the emergency notification device 10 including the communication control unit 11, the imaging unit 12, and the storage unit 14, and the camera 13. On the other hand, when the power supply is abnormal, the switch 15d is turned off to supply power from the backup power supply 16 to the communication control unit 11, and the image capturing unit 12, the storage unit 14, and the camera 13 have the backup power supply 16 Power is not supplied from.

On the other hand, when all or part of the camera 13, the storage unit 14, and the image capturing unit 12 are excluded from the power supply from the backup power supply 16, the power supply unit 15 and the like are configured as shown in FIG. It may be.

That is, the power supply unit 15 has power supply circuits 15a to 15d, a backup power supply circuit 15e, and a third power supply line 15i.
The power supply circuits 15a to 15d supply power to the communication control unit 11, the image capturing unit 12, the storage unit 14, and the camera 13, respectively. Further, the power supply circuits 15b to 15d are provided with an ON/OFF function, and the power supply circuits 15b to 15d are configured to supply power in the ON state and not supply power in the OFF state.

In addition, the third power supply line 15i supplies the power from the vehicle-mounted battery 2a to the communication control unit 11, the photographing unit 12, the storage unit 14, and the camera 13 via the power supply circuits 15a to 15d.

Further, the power supply from the backup power supply 16 is controlled. The backup power supply circuit 15e is connected to the third power supply line 15i.
Then, when the power supply is normal, all the power supply circuits 15b to 15d are turned on, and power is supplied to each part of the emergency notification device 10 including the communication control unit 11, the imaging unit 12, and the storage unit 14, and the camera 13. To do. On the other hand, when the power supply is abnormal, the power supply circuit that supplies the power to the exclusion target is turned off to stop the power supply from the backup power supply 16 to the exclusion target.

[4. About emergency calls]
As described above, when an abnormal situation occurs, the communication controller 11 of the emergency call device 10 makes an emergency call to the center 3. However, the processing performed when an abnormal situation occurs differs between when the power supply is normal and when the power supply is abnormal.

That is, when an abnormal situation occurs, if the power supply is normal, the communication control unit 11 makes an emergency notification to the center 3 and reads a photographed image immediately before the abnormal situation occurs from the storage unit 14 to the center 3. Send. On the other hand, when an abnormal situation occurs, the communication control unit 11 makes an emergency notification to the center 3 and does not transmit the captured image if the power supply is abnormal.

The center 3 is a device that can communicate with the emergency notification device 10 via the communication network 4, and stores the captured image received from the emergency notification device 10 in a storage device such as an HDD. The stored captured image is used for analysis of the cause of occurrence of an abnormal situation and the like. Further, the center 3 may have a microphone and a speaker (not shown), and the driver and the occupant of the vehicle 2 and the operator of the center 3 may be able to talk with each other by the microphone and the speaker.

In the following, an emergency call process for making an emergency call will be described with reference to the flowchart of FIG. The emergency call processing is periodically executed by the emergency call device 10 while the vehicle 2 is driving.
In S100, the image capturing unit 12 captures an image with the camera 13, and stores the captured image data in the storage unit 14 together with the image capturing time.

In S105, the communication control unit 11 determines whether a power supply abnormality has occurred. Specifically, for example, the determination may be performed based on the voltage of the power supply line used to supply the power from the vehicle-mounted battery 2a. Then, when an affirmative determination is obtained (S110: Yes), the process proceeds to S110, and when a negative determination is obtained (S110: No), the process proceeds to S115.

In S110, the communication control unit 11 starts power supply from the backup power supply 16 instead of the vehicle-mounted battery 2a. At this time, the backup power supply 16 supplies power to the power supply target, but does not supply power to the exclusion target, as described above.

In subsequent S115, the communication control unit 11 determines whether or not an abnormal situation has occurred. Specifically, for example, when a command indicating occurrence of an abnormal situation such as the above-mentioned emergency stop instruction is received from the in-vehicle network 40, it may be considered that the abnormal situation has occurred. Further, for example, when a vehicle collision is detected by an acceleration sensor (not shown) provided in the emergency notification device 10, it may be considered that an abnormal situation has occurred. Then, when an affirmative determination is obtained (S115: Yes), the process proceeds to S120, and when a negative determination is obtained (S115: No), this processing is ended.

In S120, the communication control unit 11 determines whether or not the power source is normal. If the power source is normal (S120: Yes), the process proceeds to S125, and if the power source is abnormal (S120: No), the process proceeds to S135. To do.

In S125, the communication control unit 11 makes an emergency call to the center 3. Specifically, the communication control unit 11 communicates with the center 3 via the communication network 4 and notifies that an abnormal situation has occurred. At this time, the communication control unit 11 may enable a call between the driver or the occupant of the vehicle 2 and the operator of the center 3 by using a speaker and a microphone (not shown).

In subsequent S130, the communication control unit 11 reads out the captured image stored in the storage unit 14 and transmits it to the center 3. Specifically, the communication control unit 11 transmits to the center 3 the captured image in the preceding period, which is the period before the occurrence of the abnormal situation and including the period immediately before the occurrence of the abnormal situation. Then, the process proceeds to S140.

On the other hand, in S135, the communication control unit 11 makes an emergency notification to the center 3 similarly to S125, and shifts the processing to S140. When the storage unit 14 is the power supply target, the communication control unit 11 may transmit the captured image stored in the storage unit 14 as in S130.

Here, after the emergency call, when a call becomes possible between the center 3 and the emergency call device 10, it is assumed that the driver or the passenger does not respond to the call from the operator. In such a case, if the captured image is not transmitted to the center 3 due to the power supply abnormality, the center 3 may transmit a transmission instruction, which is a command requesting the transmission of the captured image, to the emergency notification device 10. There is a nature.

In S140, the communication control unit 11 determines whether or not a transmission instruction has been received from the center 3. Then, when an affirmative determination is obtained (S140: Yes), the process proceeds to S145, and when a negative determination is obtained (S140: No), this processing is ended.

In S145, the communication control unit 11 reads and reads the captured image of the preceding period from the storage unit 14. At this time, if the storage unit 14 is an exclusion target and power is not being supplied to the storage unit 14 due to a power supply abnormality, the communication control unit 11 instructs the power supply unit 15 from the backup power supply 16 to the storage unit. After the power supply to 14 is started, the captured image is read out. On the other hand, when the storage unit 14 is the power supply target, the communication control unit 11 reads the captured image from the storage unit 14 without restarting the power supply.

Further, it is assumed that the center 3 receives a transmission instruction requesting the transmission of a newly photographed image after an abnormal situation occurs. In this case, the communication control unit 11 takes an image with the imaging unit 12 and the camera 13. At this time, when power is not supplied to the exclusion target due to power supply abnormality, the communication control unit 11 causes the power supply unit 15 to start supplying power from the backup power supply 16 to the exclusion target, and causes the image capturing unit 12 to capture an image. Instruct. In response to this, the photographing unit 12 newly photographs with the camera 13 and stores the photographed image in the storage unit 14. Then, the communication control unit 11 reads a new captured image from the storage unit 14.

In subsequent S150, the communication control unit 11 transmits the captured image read from the storage unit 14 to the center 3 and ends this processing.
[5. effect]
According to the first embodiment, the following effects are obtained.

(1) The backup power supply 16 used when the power supply abnormality of the vehicle-mounted battery 2a occurs supplies power to the communication control unit 11, but at least the camera 13, the storage unit 14, and the photographing unit 12 are provided. Part of the power is not supplied. Therefore, the power consumption of the backup power supply 16 can be suppressed, and an emergency call between the center 3 and the emergency call device 10 can be made for a longer period when an abnormal situation occurs. Therefore, when an abnormal situation occurs, the electric power stored in the backup power supply 16 can be more appropriately distributed, and the abnormal situation can be dealt with more appropriately.

(2) Further, the emergency notification device 10 is configured as an integrated device. Therefore, the emergency notification device 10 can be downsized, and the emergency notification and the captured image can be transmitted to the center 3 without being affected by the external device.

(4) Moreover, it is considered that the power consumption of the storage unit 14 is not so large. Therefore, when the storage unit 14 is used as the power supply target from the backup power supply 16 at the time of power supply abnormality, it is possible to suppress an increase in power consumption and to read a captured image from the storage unit 14 when an abnormal situation occurs. Meanwhile, it is possible to make an emergency call for a longer period.

(5) Further, when an abnormal situation occurs, the communication control unit 11 transmits the captured image stored in the storage unit 14 to the center 3 in response to an instruction from the center 3. Therefore, even when the captured image is not transmitted to the center 3 together with the emergency notification due to the power supply abnormality, the center 3 can collect the captured image when the abnormal situation occurs.

(6) Further, when an abnormal situation occurs, the communication control unit 11 newly takes a picture in accordance with an instruction from the center 3 and transmits the taken image to the center 3. Therefore, even when the operator of the center 3 cannot communicate with the driver or the occupant of the vehicle 2 when an abnormal situation occurs, the center 3 can grasp the inside or outside of the vehicle 2 and the like.
