Abstract

Provided is a system capable of reducing production costs. The system (on-board device) comprises an acquisition unit provided in a vehicle and comprising a camera unit that captures images and/or a microphone unit that captures sound; and an error detection unit that detects vehicle errors. The system sends the acquisition results from the acquisition unit, such as images and sound, to outside the vehicle in conjunction with a mobile information terminal provided in the vehicle, when the error detection unit has detected an error. Ideally, the mobile information terminal has a rechargeable battery unit and the acquisition unit and/or the error detection unit have power supplied thereto from the battery unit in the mobile information terminal, and can operate thereby. Also, the error detection unit ideally changes the error detection mode in accordance with the state of the battery unit in the mobile information terminal.

Claims

1. A vehicle monitoring system comprising:

an acquisition unit provided in a vehicle, said acquisition unit configured to acquire at least one of images or sounds; and

an error detection unit provided in the vehicle, said error detection unit configured to detect errors in the vehicle,

when the error detection unit has detected an error, acquisition results output from the acquisition unit are sent outside the vehicle via a mobile information terminal provided in the vehicle,

the mobile information terminal comprises a rechargeable battery unit, and the acquisition unit, of an on-board device, is powered by the rechargeable battery unit of the mobile information terminal,

the mobile information terminal is configured to change an error detection mode of the error detection unit in accordance with a state of the rechargeable battery unit in the mobile information terminal,

a power source unit of the on-board device is configured to recharge the rechargeable battery unit by using power from an on-board battery, and

the power source unit of the on-board device is also powered by the on-board battery in accordance with a state of the on-board battery.

2. The system of claim 1, the error detection unit is powered by the rechargeable battery unit of the mobile information terminal, and the acquisition unit and the error detection unit are allowed to operate.

3. The system of claim 2, the error detection unit is powered by the on-board battery in accordance with the state of the on-board battery, and the acquisition unit and the error detection unit are allowed to operate.

4. The system of claim 1, the error detection unit is configured to synchronize a sensor unit of the mobile information terminal with a sensor unit of the on-board device to detect the errors.

5. The system of claim 1, further comprising the mobile information terminal.

6. The system of claim 1, further comprising a mobile information terminal for receiving the acquisition results sent from the mobile information terminal.

7. The system of claim 1, the rechargeable battery unit can be recharged by using power from the on-board battery.

8. The system of claim 2, the error detection unit is configured to synchronize a sensor unit of the mobile information terminal with a sensor unit of the on-board device to detect the errors.

9. The system of claim 3, the error detection unit is configured to synchronize a sensor unit of the mobile information terminal with a sensor unit of the on-board device to detect the errors.

10. The system of claim 2, further comprising the mobile information terminal.

11. The system of claim 3, further comprising the mobile information terminal.

12. The system of claim 4, further comprising the mobile information terminal.

13. The system of claim 2, further comprising a mobile information terminal for receiving the acquisition results sent from the mobile information terminal.

14. The system of claim 1, when a remaining life of the battery unit is equal to or less than a predetermined value, the error detection unit is configured to stop a supply of power to the acquisition units and at least one of a camera unit or a microphone unit, and can implement a sleep mode.

15. The system of claim 14, when the remaining life of the battery unit is equal to or less than the predetermined value, the error detection unit is configured to supply power to a vibration sensor unit of the acquisition unit,

and when, a predetermined value or greater is detected by the vibration sensor unit, the error detection unit is configured to restart the supply of power to the sleeping acquisition units and the camera unit and is configured to wake up at least one of the camera unit and the microphone unit at the detection of vibration by the vibration sensor unit.

16. The system of claim 1, after a connection between the mobile information terminal and the error detection unit is established, the error detection unit is configured to detect the errors in the vehicle.

17. The system of claim 16, after the connection between the mobile information terminal and the error detection unit is terminated, the error detection unit is configured to stop detecting the errors in the vehicle.
