ABSTRACT:
Anticipatory crash sensors mounted on the front of a vehicle or optionally on the sides sense the speed of approach to an obstacle. A signal processing algorithm determines the ratio of the speed to a threshold and multiplies the output of an accelerometer with the ratio. This enhanced acceleration signal is input to a single point crash sensor algorithm to reduce the time to generate a trigger signal.
