METHOD AND SYSTEM FOR DETERMINING A PRIMARY DIRECTION OF FORCE RESULTING FROM A VEHICLE COLLISION

A vehicle comprises an acceleration sensing module and a crash direction-computing module. The acceleration-sensing module is configured for generating acceleration information resulting from a vehicle collision event. The acceleration information includes a first direction acceleration value and a second direction acceleration value. The crash direction-computing module is coupled to the acceleration-sensing module for receiving the acceleration information therefrom and is configured for determining impact direction information resulting from the vehicle collision event. Generating the impact direction information includes deriving a first direction delta velocity value from the first direction acceleration value, deriving a second direction delta velocity value from the second direction acceleration value, determining a first delta velocity threshold value based on a delta velocity threshold angle and the first direction delta velocity value, and determining an impact zone based on the first delta velocity threshold value and the second direction delta velocity value.
