Abstract

본 발명은 시트 벨트의 풀린 길이에 따라 에어백의 전개시간을 제어하여 최적의 안전을 도모하도록 한 에어백 전개시간 제어방법에 관한 것이다.The present invention relates to an airbag deployment time control method for achieving optimal safety by controlling the deployment time of the airbag according to the unwinding length of the seat belt.

종래의 에어백 전개방법은 충돌 세기가 기준 임계치보다 크면 운전자의 위치와는 무관하게 일정한 알고리즘에 의해 에어백이 전개 됨으로써 운전자의 안전을 최대로 확보하지 못하는 문제점이 있었다.In the conventional airbag deployment method, when the collision intensity is greater than the reference threshold, the airbag is deployed by a constant algorithm regardless of the driver's position, thereby preventing the driver's safety to the maximum.

본 발명은 시트벨트의 길이로 운전자의 위치를 판단하고 그 판단한 운전자의 위치에 따라 에어백의 전개시간을 콘트롤하여 에어백을 전개시킴으로써 충돌 사고시 운전자의 안전을 도모하게 되는 것이다.According to the present invention, the driver's position is determined by the length of the seat belt, and the airbag is deployed by controlling the deployment time of the airbag according to the determined driver's position to promote the driver's safety in a crash accident.

Claims (2)

자동차의 충돌로 인해 검출되는 충돌 세기와 에어백 전개를 위해 설정된 기준 임계치와를 비교하여 에어백 전개 유무를 판단하는 제1단계와, 상기 판단 결과 에어백 전개로 판단되면 시트벨트 길이 검출부를 통해 시트벨트의 풀린 길이를 측정하는 제2단계와, 상기 측정한 시트벨트의 풀린 길이로 에어백 전개시간을 산출하는 제3단계와, 상기 산출한 에어백 전개시간에 따라 에어백 전개 제어신호를 발생시켜 에어백 전개를 제어하는 제4단계로 이루어짐을 특징으로 하는 자동차의 에어백 전개시간 제어방법.A first step of determining whether the airbag is deployed by comparing the collision intensity detected due to the collision of the vehicle with a reference threshold set for deploying the airbag; and if it is determined that the airbag is deployed, the seatbelt is detected through the seat belt length detection unit. A second step of measuring a length, a third step of calculating an airbag deployment time based on the measured unwinding length of the seat belt, and an airbag deployment control signal generated according to the calculated airbag deployment time to control airbag deployment Airbag deployment time control method of a vehicle, characterized in that consisting of four steps. 제1항에 있어서, 상기 제3단계는 시트벨트의 풀린 길이가 길경우에는 에어백 전개시간이 최대로 빠르게 되도록 전개시간을 산출하고, 시트벨트의 풀린 길이가 짧은 경우에는 에어백 전개 시간이 상대적으로 느리게 되도록 전개시간을 산출하는 것을 특징으로 하는 자동차의 에어백 전개시간 제어방법.The method of claim 1, wherein the third step calculates the deployment time so that the airbag deployment time is maximized when the seatbelt length is long, and the airbag deployment time is relatively slow when the seatbelt length is short. An airbag deployment time control method for a vehicle, characterized in that the deployment time is calculated as possible. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
