Abstract: A vehicle system equipped with an apparatus for detecting a vehicle buckle may include: a buckle switch device which is turned on or off depending on whether a vehicle seat belt buckle is fastened; and a buckle detection apparatus that determines whether the vehicle seat belt buckle is fastened based on an on or off operation of the buckle switch device and diagnoses a failure of the buckle detection apparatus.

Abstract: A method of determining whether to deploy airbags includes measuring the distance between a vehicle and a forward obstacle; selecting a deceleration threshold value depending on the distance; and if the deceleration of the vehicle is greater than the deceleration threshold value, determining that the airbags should be deployed. The distance may be measured using a radar sensor of an adaptive cruise control system. The deceleration threshold value may be a small value if the distance is small, and a larger value if the distance is larger. Selecting the deceleration threshold value may include comparing the distance with at least one preset distance, selecting a small deceleration threshold value if the distance is smaller than the preset distance, and selecting a large deceleration threshold value if the distance is greater than or equal to the preset distance.
