An algorithm for evaluating information from sensors (36; 36a, 36b, 36c, 36d) interacting with strips (34; 34a, 34b, 34c, 34d) that are extended during activation of the airbag (24) determines whether the airbag has contacted an out-of-position vehicle occupant. In one embodiment, each strip includes an alternating pattern that generates a frequency in a sensor through which the strip (34; 34a, 34b, 34c, 34d) passes during deployment. The frequency generated is based upon the speed with which the strip passes by a sensor (36; 36a, 36b, 36c, 36d) and, in turn, the speed of deployment of the airbag (24). A controller (30) evaluates the frequency and the changes in frequency from the sensor during deployment. Depending upon the specific configuration of the system and the specific vehicle, a decrease in the speed of deployment of the airbag may be indicated by a decrease in the frequency of the signal. A decrease in speed of deployment may indicate that the airbag (24) is in contact with a vehicle occupant. |
