Abstract
A vehicle impact detection system (10) for controlling the actuation of an occupant safety restraint device (24) includes a sensor array (12) affixed to an outer surface (16) of the vehicle for continuously generating a two dimensional output (14) representative of the condition of the outer surface, and a processor/evaluation circuit (20) for performing advanced array signal processing on the sensor array output. The system (10) can reliably predict severe impacts within a few milliseconds of initial impact, and therefore is particularly suited for controlling the actuation of a safety restraint device in response to side impacts.
