The invention discloses an automobile safety belt with a positioning function. The automobile safety belt comprises a ribbon and a spring bolt, wherein the spring bolt is sheathed on the ribbon to slip; a first bar code is arranged on one side surface of the ribbon, and a second bar code is arranged on the side surface of the ribbon; a first scanner used for scanning the first bar code and a second scanner used for scanning the second bar code are arranged on the spring bolt; the densities of the first bar code and the second bar code are gradually increased from one end to the other end, and the density increasing speed of the first bar code is higher than that of the second bar code. The signal variation speeds output by the first scanner and the second scanner have difference, the position of the spring bolt can be accurately judged by comparing and calculating the variation difference of the difference for the signal variation speeds, and whether the safety belt is worn or not can be accurately judged based on the position of the spring bolt.
