The invention discloses an external airbag system for automobiles. The external airbag system comprises a collision sensing unit sensing the distance between a vehicle and an obstacle; a vehicle speed acquiring unit which is connected with a vehicle bus in a communication manner, a processing unit, an explosion start unit and an external airbag, wherein the vehicle speed acquiring unit acquires the current vehicle speed; the processing unit receives an obstacle distance transmitted by the collision sensing unit and vehicle speed signals uploaded by the vehicle speed acquiring unit, and calculates collision occurring time, and when a certain time threshold is reached, start signals are sent out; the explosion start unit receives the start signals sent by the processing unit, and the external airbag is inflated to be started. An external all-direction radar and a corresponding calculation unit are arranged, so that it is guaranteed that the external airbag can be started before external vehicle collision occurs. Therefore, damage to the vehicle is reduced and hurt to passersby can be reduced. The technique adopted by the external airbag system is mature and reliable and is very suitable for a wide range of popularization and use.
