A vehicle anti-collision system comprises a vehicle speed sensing unit, a distance measuring sensing unit, an electronic parking brake unit and a control unit. The vehicle speed sensing unit is used for sensing the speed of a vehicle; the distance measuring sensing unit is used for sensing the relevant distance from an obstacle around the vehicle to the vehicle; the control unit is used for calculating a period of time in which the vehicle will collide with the obstacle according to the speed of the vehicle, and the relevant distance from the obstacle to the vehicle, and controlling the electronic parking brake unit to provide brake assistance for the vehicle when the collision duration is not longer than a period of brake time. The electronic parking brake unit is arranged and matched with the vehicle speed sensing unit and the distance measuring sensing unit, brake assistance can be executed to avoid the vehicle collision situation at the condition of low-speed reversing or parking, and the arrangement cost of the system can be reduced.
