The present invention relates to a method for protecting a vehicle passenger, comprising the steps of: calculating an airbag control unit (ACU) speed, an ACU speed change, and an ACU displacement by using acceleration of the ACU; acquiring an ACU airbag speed change threshold and an ACU airbag speed threshold by using the ACU displacement and acceleration of first and second front impact sensors (FIS); and comparing the ACU speed with the ACU airbag speed threshold, and the ACU speed change with the ACU airbag speed change threshold, and inflating an airbag according to the comparison result. Accordingly, the present invention provides a method for protecting a vehicle passenger to classify a 40% offset/ 25% overlap crash type and a crash type of a National Highway Traffic Safety Administration (NHTSA) oblique test, and to simultaneously make a threshold divided into two, thereby satisfying a required time for inflating a pre-tensioner and an airbag.

    본 발명은 ACU(AIRBAG CONTROL UNIT)의 가속도를 이용하여 ACU 속도와 ACU 속도변화 및 ACU 변위를 계산하는 단계, ACU 변위, 제1 FIS의 가속도, 및 제2 FIS의 가속도를 이용하여 ACU 에어백 속도변화 임계값과 ACU 에어백 속도 임계값을 검출하는 단계, 및 ACU 속도를 ACU 에어백 속도 임계값과 비교하고 ACU 속도변화를 ACU 에어백 속도변화 임계값과 비교하여 비교 결과에 따라 에어백을 전개시키는 단계를 포함하는 것을 특징으로 한다.
