Abstract:
1. An external airbag deployment method comprising: setting, by a controller, a detection area located in front of a vehicle based on a full deployment time of an external airbag and a relative velocity upon colliding with another object; selecting, by the controller, a target object from objects detected in the detection area by comparing a relative velocity, an overlap, and a Time To External Airbag (EAB) (TTE), which is a remaining time until an airbag cushion collides with each object when the external airbag is predicted to be deployed; and deploying, by the controller, the external airbag when a relative velocity and an overlap, predicted when a collision with the target object occurs, are greater than predetermined levels, wherein the setting the detection area includes: wherein the detection area includes a minimum value corresponding to a position closest to the vehicle and a maximum value corresponding to a position farther from the vehicle, wherein the minimum value is calculated by multiplying a minimum relative velocity by a TTE, which is the remaining time until the airbag cushion collides with the object when the external airbag is predicted to be deployed, and assign a thickness of the external airbag to the multiplied value, and wherein the minimum value is calculated by multiplying a minimum relative velocity by a TTE, which is the remaining time until the airbag cushion collides with the object when the external airbag is predicted to be deployed, and assign a thickness of the external airbag to the multiplied value.
