In-vehicle device, control method, and recording medium
An in-vehicle device to be mounted on a vehicle including an audio output device configured to output audio and an image output device configured to output an image supplies power to the audio output device during a first period from when a trigger of a passenger getting on the vehicle is detected until when first operation of powering on a power supply of the vehicle is performed, and supplies power to the audio output device and the image output device during a second period from when second operation of shutting down the power supply of the vehicle is performed until when the passenger getting off the vehicle is detected.
1. An in-vehicle device to be mounted on a vehicle including an audio output device configured to output audio, an image output device configured to output an image, and a controller, wherein
the controller is configured to
supply power to the audio output device during a first period from when a trigger of a passenger getting on the vehicle is detected until when first operation of powering on a power supply of the vehicle is performed,
supply power to the audio output device and the image output device during a second period from when second operation of shutting down the power supply of the vehicle is performed until when the passenger getting off the vehicle is detected, and
sense a first vehicle that approaches from behind the vehicle during the second period.
2. The in-vehicle device according to claim 1 , wherein the first period is started at a timing at which a door of the vehicle is unlocked.
3. The in-vehicle device according to claim 1 , wherein in a case where time-out occurs without the first operation being performed after the trigger is detected, a power supply of the audio output device is shut down.
4. The in-vehicle device according to claim 1 , wherein the second period is finished at a timing at which a door of the vehicle is open.
5. The in-vehicle device according to claim 1 , wherein the second period is finished at a timing at which operation of locking a door of the vehicle is performed.
6. The in-vehicle device according to claim 1 , wherein in a case where time-out occurs without getting-off of the passenger being detected after the second operation is performed, power supplies of the audio output device and the image output device are shut down.
7. The in-vehicle device according to claim 1 , wherein power is not supplied to the image output device during the first period.
8. The in-vehicle device according to claim 1 , wherein the audio output device includes an amplifier.
9. The in-vehicle device according to claim 1 , wherein the controller is configured to output an alarm via the audio output device or the image output device on a basis of a result of the sensing.
10. A control method for controlling a vehicle including an audio output device configured to output audio and an image output device configured to output an image, the control method comprising:
supplying power to the audio output device during a first period from when a trigger of a passenger getting on the vehicle is detected until when first operation of powering on a power supply of the vehicle is performed;
supplying power to the audio output device and the image output device during a second period from when second operation of shutting down the power supply of the vehicle is performed until when the passenger getting off the vehicle is detected; and
sensing a vehicle that approaches from behind the vehicle during the second period.
11. The control method according to claim 10 , wherein the first period is started at a timing at which a door of the vehicle is unlocked.
12. The control method according to claim 10 , wherein in a case where time-out occurs without the first operation being performed after the trigger is detected, a power supply of the audio output device is shut down.
13. The control method according to claim 10 , wherein the second period is finished at a timing at which a door of the vehicle is open or a timing at which operation of locking the door of the vehicle is performed.
14. The control method according to claim 10 , wherein in a case where time-out occurs without getting-off of the passenger being detected after the second operation is performed, power supplies of the audio output device and the image output device are shut down.
15. The control method according to claim 10 , wherein power is not supplied to the image output device during the first period.
16. The control method according to claim 10 , wherein the audio output device includes an amplifier.
17. The control method according to claim 10 , further comprising outputting an alarm via the audio output device or the image output device on a basis of a result of the sensing.
18. A non-transitory computer-readable recording medium recorded with a program for causing a computer to execute a control method for controlling a vehicle including an audio output device configured to output audio and an image output device configured to output an image, the control method comprising:
supplying power to the audio output device during a first period from when a trigger of a passenger getting on the vehicle is detected until when first operation of powering on a power supply of the vehicle is performed;
supplying power to the audio output device and the image output device during a second period from when second operation of shutting down the power supply of the vehicle is performed until when the passenger getting off the vehicle is detected; and
sensing a vehicle that approaches from behind the vehicle during the second period.
