Abstract:
A method for continuous collision severity prediction, the method comprising:receiving vehicle acceleration data from a sensing and diagnostic module (SDM) accelerometer and at least one electronic front sensor (EFS) accelerometer; detecting a collision event in response to said receiving and to said acceleration data; calculating velocity and displacement for said EFS and said SDM in response to said detecting, said calculating velocity and displacement responsive to said acceleration data; determining a collision mode in response to said detecting, wherein input to said determining includes said EFS velocity, said EFS displacement, said SDM velocity and said SDM displacement; calculating a collision severity value responsive to said SDM velocity, to said SDM displacement and to said collision mode, wherein said collision severity value corresponds to a percentage inflation level of an airbag, said percentage inflation level along a continuum ranging from not deployed to fully deployed; and continuously monitoring said SDM velocity and said SDM displacement.
