The invention discloses an automobile outside airbag system capable of changing the expansion degree along with the automobile speed. The automobile outside airbag system comprises a collision sensing unit, an automobile speed acquisition unit, a processing unit, an explosion starting unit and an outside airbag, wherein the collision sensing unit senses the distance between an automobile and an obstacle; the automobile speed acquisition unit is in communication connection with the automobile through a bus, and acquires the current automobile speed; 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 time, and sends a starting signal when a certain time threshold value is reached; the explosion starting unit receives the starting signal sent by the processing unit, inflates the outside airbag, and opens the outside airbag; through arrangement of an external omnibearing radar and a corresponding computing unit, the outside airbag can be ensured to be opened before external collision of the automobile, so that damage to the automobile can be reduced; through adoption of a modularized explosion starting unit, the outside airbag can be opened completely or partially according to the current automobile speed. The automobile outside airbag system is mature in technology and is very suitable for wide-range popularization and application.
