Abstract

An on-vehicle emergency notification device that performs notification processing when an emergency event of a vehicle occurs, using a power accumulated in a battery mounted on the vehicle, includes: a voice communication unit that performs voice communication with a notification center via a voice call when the emergency event occurs; and an image sending unit that wirelessly sends images around the vehicle to the notification center when the emergency event occurs. After the emergency event occurs, a wireless sending of images by the image sending unit is inhibited if a battery power level of the battery becomes lower than a predetermined value.

Claims

1. An on-vehicle emergency notification device that performs notification processing when an emergency event of a vehicle occurs, using a power accumulated in a battery mounted on the vehicle, the device comprising:

a voice communication unit configured to perform voice communication with a notification center via a voice call at the timing the emergency event occurs; and

an image sending unit configured to wirelessly send automatically images around the vehicle to the notification center at the timing the emergency event occurs, wherein

after the emergency event occurs, a wireless sending of images by the image sending unit is inhibited when a battery power level of the battery becomes lower than a predetermined value required for performing the voice communication with the notification center via the voice call, and

the image sending unit preferentially sends images captured immediately before the emergency event for verifying cause of the emergency event.

2. The on-vehicle emergency notification device according to claim 1 wherein

when the emergency event occurs, the image sending unit gives priority to images around the vehicle according to content of the emergency event and preferentially sends highly prioritized images wirelessly.

3. The on-vehicle emergency notification device according to claim 2 wherein

the image sending unit gives a high priority to images captured a predetermined time before a time when the emergency event occurred.

4. The on-vehicle emergency notification device according to claim 2 wherein

the image sending unit gives a high priority to images captured a predetermined distance before a position where the emergency event occurred.

5. The on-vehicle emergency notification device according to claim 2 wherein

the image sending unit gives a high priority to images captured in a direction of an impact force when the emergency event occurred.

6. The on-vehicle emergency notification device according to claim 1 wherein

the battery power level of the battery is determined each time an image is wirelessly sent via the image sending unit.

7. The on-vehicle emergency notification device according to claim 1 wherein

the battery power level of the battery is determined by a remaining amount of battery power calculated by subtracting an amount of power required for sending the images to be wirelessly sent from an amount of power accumulated in the battery.

8. The on-vehicle emergency notification device according to claim 1 wherein

occurrence detection sensitivity to the emergency event is increased when a pedestrian is detected as an images around the vehicle.

9. The on-vehicle emergency notification device according to claim 1 wherein

the battery is a backup battery that is an emergency battery and the backup battery is a secondary battery.
