Abstract

A vehicle includes a safety device, a camera sensor configured to detect an obstacle around the vehicle, a radar sensor configured to detect the obstacle around the vehicle, and a controller configured to predict a collision state and a collision position of the vehicle through the camera sensor and the radar sensor, determine whether to control the safety device based on at least one of a vehicle type, a collision speed, a seat position of an occupant, whether the occupant wears a seat belt, a gender of the occupant, whether the occupant is an infant, or a size of the occupant, in response to a prediction result, and control the safety device depending on device determination result.

First claim

What is claimed is:

1. A vehicle comprising:
a safety device;
a camera sensor to detect an obstacle around the vehicle;
a radar sensor to detect the obstacle around the vehicle; and
a controller configured to:
predict a collision state and a collision position of the vehicle through the camera sensor and the radar sensor;
determine whether to control the safety device based on at least one of a vehicle type, a collision speed, a seat position of an occupant, whether the occupant wears a seat belt, a gender of the occupant, whether the occupant is an infant, or a size of the occupant, in response to a prediction result; and
control the safety device depending on a determination result.

2. The vehicle according to claim 1 , wherein the controller is configured to:
determine an unfolding speed of the safety device.

3. The vehicle according to claim 1 , wherein the controller is configured to:
predict that the collision position of the vehicle is in a direction of a driver seat when:
an overlap ratio detected by the camera sensor is greater than or equal to 0% and less than 50%,
a difference between an absolute value of acceleration detected by a front collision detection sensor mounted in the direction of the driver seat and an absolute value of acceleration detected by a front collision detection sensor mounted in a direction of a passenger seat is greater than a first value, and
an acceleration detected by an air bag control unit (ACU) is greater than a second value.

4. The vehicle according to claim 1 , wherein the controller is configured to:
predict that the collision position of the vehicle is in a direction of a passenger seat when:
an overlap ratio detected by the camera sensor is greater than or equal to 50% and equal to or less than 100%,
a difference between an absolute value of acceleration detected by a front collision detection sensor mounted in a direction of a driver seat and an absolute value of acceleration detected by a front collision detection sensor mounted in the direction of the passenger seat is less than a third value, and
an acceleration detected by an air bag control unit (ACU) is less than a fourth value.

5. The vehicle according to claim 1 , wherein the safety device comprises at least one of a driver air bag (DAB), a passenger air bag (PAB), or a pretensioner (PT).

6. The vehicle according to claim 1 , wherein the controller is configured to:
control at least one of a driver air bag (DAB) or a passenger air bag (PAB) to operate based on the seat position of the occupant when the collision speed of the vehicle is greater than or equal to 9 mph and less than or equal to 14 mph, and the occupant does not wear a seat belt.

7. The vehicle according to claim 1 , wherein the controller is configured to:
control a pretensioner (PT) to operate based on the seat position of the occupant when the collision speed of the vehicle is 11 mph and the occupant wears a seat belt.

8. The vehicle according to claim 1 , wherein the controller is configured to:
control a pretensioner (PT) and at least one of a driver air bag (DAB) or a passenger air bag (PAB) to operate based on the seat position of the occupant when the collision speed of the vehicle is greater than or equal to 14 mph and the occupant wears a seat belt.

9. The vehicle according to claim 1 , wherein the collision position of the vehicle is at least one of a direction of a driver seat or a direction of a passenger seat.

10. A control method of a vehicle comprising:
predicting, by a camera sensor and a radar sensor, a collision state and a collision position of the vehicle;
determining whether to control a safety device based on at least one of a vehicle type, a collision speed, a seat position of an occupant, whether the occupant wears a seat belt, a gender of the occupant, whether the occupant is an infant or a size of the occupant, in response to a prediction result; and
controlling the safety device depending on a determination result.

11. The control method according to claim 10 , further comprising:
determining an unfolding speed of the safety device.

12. The control method according to claim 10 , further comprising:
predicting that the collision position of the vehicle is in a direction of a driver seat when:
an overlap ratio detected by the camera sensor is greater than or equal to 0% and less than 50%,
a difference between an absolute value of acceleration detected by a front collision detection sensor mounted in the direction of the driver seat and an absolute value of acceleration detected by a front collision detection sensor mounted in a direction of a passenger seat is greater than a first value, and
an acceleration detected by an air bag control unit (ACU) is greater than a second value.

13. The control method according to claim 10 , further comprising:
predicting that the collision position of the vehicle is in a direction of a passenger seat when:
an overlap ratio detected by the camera sensor is greater than or equal to 50% and less than or equal to 100%,
a difference between an absolute value of acceleration detected by a front collision detection sensor mounted in a direction of a driver seat and an absolute value of acceleration detected by a front collision detection sensor mounted in the direction of the passenger seat is less than a third value, and
an acceleration detected by an air bag control unit (ACU) is less than a fourth value.

14. The control method according to claim 10 , wherein the safety device comprises at least one of a driver air bag (DAB), a passenger air bag (PAB), or a pretensioner (PT).

15. The control method according to claim 10 , further comprising:
controlling at least one of a driver air bag (DAB) or a passenger air bag (PAB) to operate based on the seat position of the occupant when the collision speed of the vehicle is greater than or equal to 9 mph and less than or equal to 14 mph and the occupant does not wear a seat belt.

16. The control method according to claim 10 , further comprising:
controlling a pretensioner (PT) to operate based on the seat position of the occupant when the collision speed of the vehicle is 11 mph and the occupant wears a seat belt.

17. The control method according to claim 10 , further comprising:
controlling a pretensioner (PT) and at least one of a driver air bag (DAB) or a passenger air bag (PAB) to operate based on the seat position of the occupant when the collision speed of the vehicle is greater than or equal to 14 mph and the occupant wears a seat belt.
