1. A crash detection system comprising:

  • a plurality of sensors located at different points of a vehicle, at least two of said plurality of sensors making measurements relating to velocity at a first point and at a second point in a forward direction of travel and at least two of said plurality of sensors making measurements relating to velocity along a direction of travel transverse to forward travel at a third point and at a fourth point; and

    an evaluation unit for reading and comparing the measurements of said plurality of sensors to determine a severity of a vehicle crash by examining a difference in the measurements from said plurality of sensors wherein the difference comprises a comparison of a first rate of movement of the first point of the vehicle compared with a second rate of movement of the second point of the vehicle along the forward direction and a comparison of a third rate of movement of the third point of the vehicle with a fourth rate of movement of the fourth point of the vehicle along the direction transverse to the forward direction.
