To reliably deploy a lateral airbag with no malfunction not only in the case of a side collision of a vehicle but also in the case of a diagonal collision thereof.SOLUTION: An airbag deployment method includes: a step B2 of detecting longitudinal acceleration that is acceleration in a longitudinal direction of a vehicle and lateral acceleration that is acceleration in a lateral direction of the vehicle; steps B3, B4 and B7 of calculating a deployment threshold of a lateral airbag on the basis of the longitudinal acceleration; and steps B5, B6 and B8 of deploying the lateral airbag when the lateral acceleration is the deployment threshold or above. The steps of calculating the deployment threshold have a process B5 in which the deployment threshold is set lower when the longitudinal acceleration becomes higher.SELECTED DRAWING: Figure 6

    【課題】車両の側突に限らず、斜突の場合でも、側面エアバッグを誤作動なく確実に展開させる。【解決手段】車両の前後方向の加速度である縦加速度と車両の横方向の加速度である横加速度を検出するステップB2と、縦加速度に基づいて側面エアバッグの展開閾値を算出するステップB3,B4,B7と、横加速度が展開閾値以上であるときに側面エアバッグを展開させるステップB5,B6,B8とを備え、上記展開閾値を算出するステップは、縦加速度が大きくなるほど上記展開閾値が小さくなるようにするプロセスB5を有する。【選択図】図6
