wherein the driving manipulation pattern for performing steering includes a mismatch of a manipulation direction of the steering wheel and a direction of a route displayed on a map of a navigation system in the vehicle.
2. The method of claim 1 ,
wherein a collision avoidance intent of the driver is determined from the pattern of the driver manipulating the vehicle; and
wherein the possibility of collision of the vehicle is determined from a result of the determination of the collision avoidance intent.
3. The method of claim 2 , wherein the driving manipulation pattern of the vehicle includes a driving manipulation pattern for performing at least one of decelerating, braking, or steering of the vehicle.

5. The method of claim 3 , wherein the driving manipulation pattern for performing decelerating includes at least one of a revolution per minute (rpm) of an engine of the vehicle being reduced by manipulation of an accelerator pedal or an opening degree of a throttle valve of the engine of the vehicle being reduced by manipulation of the accelerator pedal.
6. The method of claim 1 , wherein when a possibility of collision of the vehicle is determined to be present, the threshold value for deployment of the airbag is adjusted to be lowered such that a possibility of deployment of the airbag is increased.
7. The method of claim 6 , wherein the adjusting of the threshold value for deployment of the airbag includes a plurality of different threshold values.

wherein the driving manipulation pattern of the vehicle includes manipulating a steering wheel of the vehicle, and
wherein the driving manipulation pattern for performing steering includes a mismatch of a manipulation direction of the steering wheel and a direction of a route displayed on a map of a navigation system in the vehicle.
9. The vehicle of claim 8 ,
wherein the controller is configured to:
determine a collision avoidance intent of the driver from the pattern of the driver manipulating the vehicle; and
determine the possibility of collision of the vehicle from a result of the determination of the collision avoidance intent.
10. The vehicle of claim 8 , wherein the driving manipulation pattern of the vehicle includes a driving manipulation pattern for performing at least one of decelerating, braking, or steering of the vehicle.
11. The vehicle of claim 10 , wherein the driving manipulation pattern for performing braking includes at least one of: a speed of the vehicle being reduced by manipulation of a brake pedal; a pressure of a brake of the vehicle being increased by manipulation of the brake pedal; or an anti-lock brake system (ABS) of the vehicle being activated by manipulation of the brake pedal.
12. The vehicle of claim 10 , wherein the driving manipulation pattern for performing decelerating includes at least one of a revolution per minute (rpm) of an engine of the vehicle being reduced by manipulation of an accelerator pedal or an opening degree of a throttle valve of the engine of the vehicle being reduced by manipulation of the accelerator pedal.
13. The vehicle of claim 8 , wherein the adjusting of the threshold value for deployment of the airbag includes a plurality of different threshold values.
14. A method of controlling an airbag of a vehicle, the method comprising:
determining a collision avoidance intent of a driver of the vehicle from a driving manipulation pattern of the driver of the vehicle;
detecting a value of at least one sensor of the vehicle;
determining a possibility of collision of the vehicle from a result of the determination of the collision avoidance intent of the driver and the value of the at least one sensor of the vehicle; and
variably adjusting a threshold value for deployment of the airbag on the basis of a result of the determination of the possibility of collision, wherein in response to a possibility of collision determined to be present, the threshold value for deployment of the airbag is adjusted to be lowered such that a possibility of deployment of the airbag is increased,
wherein the driving manipulation pattern of the vehicle includes manipulating a steering wheel of the vehicle, and
wherein the driving manipulation pattern for performing steering includes a mismatch of a manipulation direction of the steering wheel and a direction of a route displayed on a map of a navigation system in the vehicle.
