1. A method for controlling gas pressure for inflating a passenger-side frontal airbag in a vehicle, comprising:
- determining whether at least one passenger is resident in the passenger seat;
determining a number of passengers and a current passenger type corresponding to the at least one passenger when at least one passenger is resident in the passenger seat, the current passenger type being selected from a plurality of predetermined passenger types;
determining whether the number of the at least one passenger is not one;
determining, in the case that the number of the at least one passenger is not one, whether a collision occurs;
determining, in the case of a vehicle collision, whether the vehicle collision is a frontal collision;
detecting, in the case of the frontal collision, a frontal impact generated from the vehicle collision; and
adjusting the gas pressure for inflating the passenger-side frontal airbag on the basis of the current passenger type and the frontal impact generated from the collision;
wherein when the current passenger type is a child only type, the adjusting the gas pressure comprises;
determining whether the detected frontal impact is larger than a first predetermined impact (Im_1); and
determining whether the detected frontal impact is larger than a second predetermined impact (Im_2 wherein Im_2>
Im_1),wherein when the detected frontal impact is not larger than the first predetermined impact the passenger-side airbag is not operated,wherein when the detected impact is larger than the first predetermined impact (Im_1) and is not larger than the second predetermined impact (Im_2) the gas pressure is formed to be 25% of a normal pressure (P_normal), andwherein when the detected impact is larger than the second predetermined impact (Im_2) the gas pressure is formed to be 50% of the normal pressure (P_normal).

Abstract
A method for controlling gas pressure for inflating a passenger-side frontal airbag in a vehicle comprises a determination of the type and number of passengers in the passenger seat and a determination of the nature and severity of the impact. When at least one passenger is resident in the passenger seat, the current passenger type is selected from a plurality of predetermined passenger types. The gas pressure for inflating the passenger-side frontal airbag is adjusted on the basis of the current passenger type and number, and the frontal impact generated from the collision.
