A vehicle crash sensing arrangement includes an accelerometer (12). A crash velocity value (26) is determined in response to sensed crash acceleration. A crash displacement value (32) is determined from the sensed crash acceleration. A velocity varying displacement threshold value (36) determined. The crash displacement value (32) is compared (38) against the variable displacement threshold value (36). The comparator (38) provides a signal indicative of a vehicle crash condition when the crash displacement value is greater than the displacement threshold value. |
