The invention discloses an automobile external airbag system for changing a collision expansion position according to a member in an automobile. The system is provided with explosion starting units, an external airbag, a collision sensing unit for sensing a distance between the automobile and a barrier, an automobile speed acquisition unit which is in communication connection with an automobile bus and used for acquiring the current automobile speed, a pressure sensor arranged below a chair in the automobile, and a processing unit, wherein the explosion starting units and the external airbag are at least fixed on a front bumper, an automobile door and a rear bumper; the pressure sensor senses whether a person rides on the corresponding chair; the processing unit receives a collision object distance transmitted by the collision sensing unit and an automobile speed signal uploaded by the automobile speed acquisition unit, computes the collision occurrence time, and emits a starting signal when a certain time threshold is reached; the explosion starting units receive the starting signal emitted by the processing unit, inflate the external airbag and open the external airbag; and the processing unit controls starting of the external airbag nearby the person according to reported person riding information.
