VEHICLE PREVENTION AIRBAG SYSTEM

A vehicle prevention airbag system includes an airbag prevention device and a threat detection device including a collision assessment unit and a sensor module for detecting threat objects or obstacles approaching the vehicle and to assess the collision probability between the threat object or obstacle and the vehicle. The airbag prevention device includes an airbag expansion controller and an external airbag module. When collision probability between the threat object and the vehicle is equal to or greater than a safety threshold, the threat detection device establishes a first collision determination message. The airbag prevention device expands at least one prevention airbag in the direction corresponding to the impact based on the first collision determination message. When the vehicle is impacted and may collide with an obstacle, a second collision determination message is established. The external airbag is expanded in the direction corresponding to the second collision determination message.
