ABSTRACT:
A vehicle crash sensing system for making omnidirectional acceleration measurements comprises 1) an assembly (26) of at least three preferably self-testable accelerometers (10, 12, 14) mounted in an array on a substantially common plane (16) with axes (18, 20, 22) both skewed relative to one another and intersecting a region near a point, and 2) an electronic control module (30). The accelerometer signals (A, B, C) provide a redundant measure of the associated acceleration vector (R). The magnitudes of components for associated acceleration basis vectors are calculated from the accelerometer signals (A, B, C) and used in the detection of crashes for associated safety restraint systems (801, 802, 803, 804). Algorithms (500, 600, 700) in the electronic control module remove accelerometer offset, determine if the acceleration measurements are self-consistent whereby the measurement of acceleration from one accelerometer is consistent with a corresponding estimate thereof based upon measurements of acceleration from the other accelerometers, control self-testing, detect crashes using only self-consistent acceleration measurements, and activate associated safety restraint systems (801, 802, 803, 804) as appropriate.
