1. An anti-theft system of a vehicle comprising:

  • a plurality of detection units that detect an impact applied to the vehicle; and

    a control device that executes;

    a detection unit identification process for identifying a detection unit that detects the impact first on the basis of values of signals from the plurality of detection units;

    an impact location estimation process for estimating that the impact is applied to a window glass when a value of a signal from the identified detection unit is greater than or equal to a predetermined threshold value, and estimating that the impact is applied to a vehicle body when the value of the signal from the identified detection unit is less than the predetermined threshold value; and

    an impact location identification process for estimating a distance between the estimated detection unit and a generation source of the impact by a correction coefficient for a case that the estimated impact location is the window glass when the estimated impact location is the window glass, estimating the distance between the estimated detection unit and the generation source of the impact by a correction coefficient for a case that the estimated impact location is the vehicle body when the estimated impact location is the vehicle body, and identifying an impact location from the window glass, the vehicle body, and other locations on the basis of the estimated distance.
