Abstract:
1. An airbag control system, comprising: a sensor unit monitoring status of a vehicle being driven and an object located in front of the vehicle; an interior airbag deployed to an interior of the vehicle being driven; an exterior airbag deployed to an exterior of the vehicle being driven; and a control unit measuring a relative speed between the vehicle being driven and the object located in front of the vehicle from the sensor unit; wherein the control unit deploys the exterior airbag when an expected time period until collision of the vehicle against the object located in front of the vehicle is equal to or less than a first critical value, the relative speed of the vehicle relative to the object located in front of the vehicle is equal to or exceeds a first exterior critical speed, and an overlapping value of a width of the object located in front of the vehicle that is overlapped with respect to a width of the vehicle being driven in the event of a collision is equal to or larger than a predetermined overlap value; and wherein the control unit, only when the exterior airbag has been deployed, compares the relative speed to a second interior critical speed and subsequently deploys the interior airbag if the relative speed exceeds the second interior critical speed.
