Abstract
An apparatus for determining a pitch-over condition of a vehicle comprises a first accelerometer for sensing acceleration in a Z-axis direction substantially perpendicular to both a front-to-rear axis of the vehicle and a side-to-side axis of the vehicle and for providing a first acceleration signal indicative thereof. A second accelerometer for senses acceleration in an X-axis direction substantially parallel to said front-to-rear axis of the vehicle and provides a second acceleration signal indicative thereof. A controller determines a Z-axis velocity value from the first acceleration signal and a pitch-over condition of the vehicle in response to both the determined Z-axis velocity value and the second acceleration signal.
