Abstract

An embodiment apparatus for recording a video in a parked vehicle includes an impact detection module configured to detect an impact applied to the parked vehicle parked in a neutral state (N-state) parking mode, wherein, in the N-state parking mode, an engine is in an ignition-off state and a gear shift lever is in a neutral state, a control module configured to determine, based on an air pressure of a tire or a wavelength of a radar reception signal, whether the parked vehicle is moving, in response to detection of the impact, and a camera module configured to record a video of surroundings of the parked vehicle, in response to a determination that the parked vehicle is moving.

First claim

What is claimed is:

1. An apparatus for recording a video in a parked vehicle, the apparatus comprising:
a processor; and
a memory with instructions stored thereon, wherein the instructions, when executed by the processor, enable the apparatus to:
detect an impact applied to the parked vehicle parked in a neutral state (N-state) parking mode, wherein, in the N-state parking mode, an engine is in an ignition-off state and a gear shift lever is in a neutral state,

determine, based on an air pressure of a tire or a wavelength of a radar reception signal, whether the parked vehicle is moving, in response to detection of the impact, and
record a video of surroundings of the parked vehicle, in response to a determination that the parked vehicle is moving, wherein when the parked vehicle moves forward or backward by an external force, shaking of the parked vehicle changes each of the air pressure of the tire and the wavelength of the radar reception signal.

2. The apparatus of claim 1 , wherein the instructions, when executed by the processor, further enable the apparatus to, in response to detection of the impact, transmit a wake-up signal to a tire pressure monitor and to a radar configured to detect a passenger in the parked vehicle.

3. The apparatus of claim 2 , wherein the instructions, when executed by the processor, further enable the apparatus to:
periodically receive, from the tire pressure monitor, an amount of change in the air pressure based on the air pressure of the tire; and
periodically receive, from the radar, an amount of change in the wavelength of the radar reception signal reflected and received from an inside of the parked vehicle.

4. The apparatus of claim 3 , wherein the instructions, when executed by the processor, further enable the apparatus to:
determine that the parked vehicle is moving when the amount of change in the air pressure of the tire received from the tire pressure monitor is greater than or equal to a preset first reference value or when the amount of change in the wavelength of the radar reception signal received from the radar module is greater than or equal to a preset second reference value.

5. The apparatus of claim 2 , wherein:
the tire pressure monitor is configured to measure the air pressure of the tire and to periodically transmit a first movement flag to the apparatus when an amount of change in the air pressure based on the air pressure of the tire is greater than or equal to a preset first reference value; and
the radar is configured to transmit a radar transmission signal to an inside of the parked vehicle and to periodically transmit a second movement flag to the apparatus when an amount of change in the wavelength of the radar reception signal reflected and received from the inside of the parked vehicle is greater than or equal to a preset second reference value.

6. The apparatus of claim 5 , wherein the instructions, when executed by the processor, further enable the apparatus to determine that the parked vehicle is moving in response to receiving the first movement flag or the second movement flag.

7. The apparatus of claim 1 , wherein the instructions, when executed by the processor, further enable the apparatus to detect that the impact is applied to the parked vehicle, when an amount of the impact of the parked vehicle is greater than or equal to a preset value.

8. The apparatus of claim 1 , wherein the instructions, when executed by the processor, further enable the apparatus to transmit, to an outside component, the video of the surroundings of the parked vehicle or a warning alarm.

9. A method for recording a video in a parked vehicle, the method comprising:
detecting an impact applied to the parked vehicle parked in a neutral state (N-state) parking mode, wherein, in the N-state parking mode, an engine is in an ignition-off state and a gear shift lever is in a neutral state;
determining, based on an air pressure of a tire or a wavelength of a radar reception signal, whether the parked vehicle is moving, in response to detection of the impact; and
recording a video of surroundings of the parked vehicle, in response to a determination that the parked vehicle is moving, wherein the air pressure of the tire and the wavelength of the radar reception signal are changed by shaking of the parked vehicle, when the parked vehicle is moved forward or backward by an external force.

10. The method of claim 9 , further comprising transmitting a wake-up signal to an air pressure measurement module for measuring the air pressure of the tire and to a radar module for detecting a passenger, in response to detecting the impact.

11. The method of claim 10 , further comprising:
measuring the air pressure of the tire and periodically transmitting an amount of change in the air pressure based on the air pressure of the tire; and
transmitting a radar transmission signal to an inside of the parked vehicle and periodically transmitting an amount of change in the wavelength of the radar reception signal reflected and received from the inside of the parked vehicle.

12. The method of claim 11 , wherein determining whether the parked vehicle is moving comprises determining that the parked vehicle is moving based on the amount of change in the air pressure of the tire being greater than or equal to a preset first reference value or the amount of change in the wavelength of the radar reception signal being greater than or equal to a preset second reference value.

13. The method of claim 10 , further comprising:
measuring the air pressure of the tire and periodically transmitting a first movement flag, when an amount of change in the air pressure based on the air pressure of the tire is greater than or equal to a preset first reference value; and
transmitting a radar transmission signal to an inside of the parked vehicle and periodically transmitting a second movement flag, when an amount of change in the wavelength of the radar reception signal reflected and received from the inside of the parked vehicle is greater than or equal to a preset second reference value.

14. The method of claim 13 , wherein determining whether the parked vehicle is moving comprises determining that the parked vehicle is moving in response to receiving the first movement flag or the second movement flag.

15. The method of claim 9 , wherein detecting the impact comprises detecting that the impact is applied to the parked vehicle based on an amount of the impact being greater than or equal to a preset value.

16. The method of claim 9 , further comprising transmitting, to an outside component, the video of the surroundings of the parked vehicle or a warning alarm.

17. A non-transitory computer-readable storage medium recording a program for causing a computer to perform the method of claim 9 .

18. The apparatus of claim 2 , further comprising the tire pressure monitor and the radar.

19. A system comprising:
a radar sensor;
a tire pressure monitor; and
a processor configured to:
detect an impact applied to a parked vehicle parked in a neutral state (N-state) parking mode, wherein, in the N-state parking mode, an engine is in an ignition-off state and a gear shift lever is in a neutral state,
determine, based on an air pressure of a tire measured by the tire pressure monitor or a wavelength of a radar reception signal measured by the radar sensor, whether the parked vehicle is moving, in response to detection of the impact, and
record a video of surroundings of the parked vehicle, in response to a determination that th
