EXTERNAL AIRBAG DEPLOYMENT METHOD AND SYSTEM

摘要

Disclosed herein is an external airbag deployment system and method of determining whether to deploy an external airbag. The method includes setting, by a controller, a detection area that has a predetermined range and selecting an object that has a shortest Time To External Airbag (EAB) (TTE), from objects detected in the detection area, as a dangerous object, the TTE being a remaining time until the object collides with an airbag cushion when the external airbag is predicted to be deployed. When the dangerous object has a relative velocity greater than a first reference, an overlap greater than a second reference, and a TTE less than a third reference, the dangerous object may be selected as a target object, to cause the external airbag to be deployed.

1. An external airbag deployment method comprising:
setting, by a controller, a detection area located in front of a vehicle; selecting, by the controller, an object having a shortest Time to External Airbag (EAB)(TTE), from a plurality of objects detected in the detection area, as a dangerous object, wherein the TTE is a remaining time until the object collides with an airbag cushion when an external airbag is predicted to be deployed; selecting, by the controller, the dangerous object as a target object, when the dangerous object has a relative velocity greater than a first reference, an overlap greater than a second reference, and a TTE less than a third reference; and deploying, by the controller, the external airbag after the dangerous object has been selected as the target object.
