Abstract

A vehicle safety system includes a motion detecting device, a control module, a positioning module, and a wireless transmitting module. The motion detecting device is configured for sensing the motion of a vehicle and recording corresponding motion data. The control module is configured for analyzing the motion data and judging whether an accident has occurred to the vehicle based upon the analysis. The positioning module is configured for obtaining position coordinates of the vehicle. The wireless transmitting module is configured for automatically making contact with and reporting the position coordinates of the vehicle to a remote service station when an accident has occurred to the vehicle.

Claims

1. A vehicle safety system comprising:

a motion detecting device configured for sensing the motion of a vehicle and recording corresponding motion data;
