The invention discloses an initiative anti-collision buffering device for an automobile. The initiative anti-collision buffering device mainly comprises a collision bumper, a buffering air cylinder, a high-pressure gas storage cylinder, an electromagnetic valve, a gas input pipe, a microprocessor and a radar sensor. When the microprocessor calculates that a collision is inevitable, the microprocessor opens the electromagnetic valve immediately, the buffering air cylinder is communicated with the high-pressure gas storage cylinder instantly, high-pressure gas in the high-pressure gas storage cylinder is immediately charged into the buffering air cylinder, and the buffering air cylinder is spread to push the collision bumper. When the collision happens, the buffering absorption of collision energy is also increased section by section along with compression of sections of the air cylinder until the air cylinder retracts completely. According to the initiative anti-collision buffering device for the automobile, the impact force of the collision has a smooth increasing process, a buffering effect is achieved on the collision, in addition, due to the fact that the measure of controlling the buffering force of the collision is added, the initiative anti-collision buffering device for the automobile can reduce the damage degree of automobiles of two colliding parts to the maximum in different-speed collision processes and can protect personnel which encounter the collision directly to the maximum; after the collision which can be controlled is completed, the buffering air cylinder is communicated with external air through the electromagnetic valve, the buffering air cylinder withdraws, and preparation is made for a next collision, and therefore the initiative anti-collision buffering device for the automobile can be repeatedly used.
