The invention discloses an automobile safety belt with a reliable positioning function. The automobile safety belt with the reliable positioning function comprises a ribbon, a winder and a locking tongue, wherein one end of the ribbon is connected with the winder; the locking tongue sleeves the ribbon in a sliding way; magnetic induction strips extending in an axial direction of the ribbon are respectively arranged at the two ends of the ribbon; a first Hall element and a second Hall element, which are used for sensing the magnetic induction strips, are respectively arranged on the winder and the locking tongue; the first Hall element and the second Hall element outputs first electric signals when sensing the magnetic induction strips and outputs second electric signals when not sensing the magnetic induction strips. According to the invention, the first Hall element and the second Hall element can output two groups of signal through working together; the winder-wound positions of the ribbon and the locking tongue can be obtained according to the two groups of signals; the wearing state of the safety belt can be accurately judged by means of the two groups of position information so as to exert a good safety prompting effect.
