Abstract

A vehicle includes a door sensor configured to detect opening and closing of a door; a radar provided in the vehicle and configured to acquire radar data regarding an object in the vehicle; a seatbelt sensor configured to detect a state of a seat belt provided on each seat of the vehicle; a seatbelt indicator configured to provide a notification regarding fastening of the seat belt; and a controller configured to control the radar in response to the opening and the closing of the door, perform a first check regarding the state of the seatbelt, check an occupancy and an occupied position of the object based on the radar data, identify a type of the object in the vehicle based on the radar data, and determine an operating state of the seatbelt indicator based on the type of the object and the occupied position of the object.

First claim

What is claimed is:

1. A vehicle comprising:
a door sensor configured to detect opening and closing of a door;
a radar provided in the vehicle and configured to acquire radar data regarding an object in the vehicle;
a seatbelt sensor configured to detect a state of a seat belt provided on each seat of the vehicle;
a seatbelt indicator configured to provide a notification regarding fastening of the seat belt; and
a controller configured to:
control the radar in response to the opening and the closing of the door;
perform a first check of confirming whether the seatbelt is fastened before the vehicle is occupied by the object;
check an occupancy and an occupied position of the object based on the radar data;
identify a type of the object in the vehicle based on the radar data;
determine an operating state of the seatbelt indicator based on the type of the object and the occupied position of the object; and
turn off the seatbelt indicator when the type of the object is not a human.

2. The vehicle of claim 1 , wherein the controller is further configured to:
perform a second check regarding the state of the seatbelt when the type of the object is a human; and
turn on the seatbelt indicator or turn off the seatbelt indicator based on a result of the second check.

3. The vehicle of claim 2 , wherein the controller is configured to:
turn on the seatbelt indicator after the first check; and
maintain the seatbelt indicator turned on or turn off the seatbelt indicator based on the result of the second check.

4. The vehicle of claim 2 , wherein the controller is configured to:
turn off the seat belt indicator when the state of the seat belt is determined to be in an unfasten state by the first check and the state of the seat belt is determined to be in a fastened state by the second check.

5. The vehicle of claim 2 , wherein the controller is configured to:
turn on the seatbelt indicator when the state of the seat belt is determined to be in an unfasten state by the first check and the state of the seat belt is determined to be in an unfastened state by the second check.

6. The vehicle of claim 2 , wherein the controller is configured to:
turn on the seat belt indicator when the state of the seat belt is determined to be in a fasten state by the first check and the state of the seat belt is determined to be switched to an unfastened state and then to a fastened state during the second check.

7. The vehicle of claim 2 , wherein the controller is configured to:
turn on the seat belt indicator when the state of the seat belt is determined to be in a fasten state by the first check and the state of the seat belt is determined to be unchanged during the second check.

8. The vehicle of claim 1 , wherein the seatbelt indicator comprises at least one of an indicator light provided in a cluster, a graphic user interface output through an audio, video, navigation (AVN) device, or a warning sound output through a speaker.

9. A method of controlling a vehicle comprising:
detecting, by a door sensor, opening and closing of a door;
when the opening and closing of the door is detected, acquiring, by a radar provided in the vehicle, radar data regarding an object in the vehicle;
performing, by a controller, a first check of confirming whether a seatbelt is fastened before the vehicle is occupied by the object;
checking, by the controller, an occupancy and an occupied position of the object based on the radar data;
identifying, by the controller, a type of the object in the vehicle based on the radar data;
determining, by the controller, an operating state of the seatbelt indicator based on the type of the object and the occupied position of the object; and
turning off the seatbelt indicator when the type of the object is not a human.

10. The method of claim 9 , wherein determining the operating state of the seatbelt indicator further comprises:
when the type of the object is a human, performing a second check regarding the state of the seatbelt; and
turning on the seatbelt indicator or turning off the seatbelt indicator based on a result of the second check.

11. The method of claim 10 , wherein the method further comprises:
turning on the seatbelt indicator after the first check;
maintaining the seatbelt indicator turned on or turn off the seatbelt indicator based on the result of the second check.

12. The method of claim 10 , wherein determining the operating state of the seatbelt indicator further comprises:
turning off the seat belt indicator based on the state of the seat belt is determined to be in an unfasten state by the first check and the state of the seat belt is determined to be in a fastened state by the second check.

13. The method of claim 10 , wherein determining the operating state of the seatbelt indicator further comprises:
turning on the seat belt indicator based on the state of the seat belt is determined to be in an unfasten state by the first check and the state of the seat belt is determined to be in an unfastened state by the second check.

14. The method of claim 10 , wherein determining the operating state of the seatbelt indicator further comprises:
turning off the seat belt indicator based on the state of the seat belt is determined to be in a fasten state by the first check and the state of the seat belt is determined to be switched to an unfastened state and then to a fastened state during the second check.

15. The method of claim 10 , wherein determining the operating state of the seatbelt indicator further comprises:
turning off the seat belt indicator based on the state of the seat belt is determined to be in a fasten state by the first check and the state of the seat belt is determined to be unchanged during the second check.

16. The method of claim 9 , wherein the seatbelt indicator comprises at least one of an indicator light provided in a cluster, a graphic user interface output through an audio, video, navigation (AVN) device, or a warning sound output through a speaker.
