The invention aims at realizing an automobile anti-collision system capable of greatly improving the medium-low speed safety of an automobile. The system consists of two parts, namely a control system and an anti-collision buffer system. Data is acquired by a distance measuring sensor and a speed measuring sensor of the control system and is transmitted to a data acquisition and processing circuit; and the processing circuit firstly judges whether a control circuit is started. When the control circuit is needed to be started, the control circuit opens an electric valve; and an airbag is charged by a gas storage bottle of a brake system. The airbag ejects out after pushing away a baffle so as to exert the buffering action. When the collision occurs, an air escape valve is opened to discharge the air; the air bag is put back into the baffle manually; and the gas bottle charges the airbag again and the automobile is restored to a next working status. The automobile anti-collision system can be installed before a novel automobile leaves a factory or be installed through the repacking of the prior automobile so as to prevent and reduce the damage to the automobile caused by collision. The automobile anti-collision system is simple, feasible, economical and practical without affecting the appearance of the automobile.
