Abstract
Method and apparatus for sensing a crash of a vehicle in which acceleration and angular motion of the vehicle are measured and analyzed by a processor to determine whether a crash is occurring. A deployable occupant protection device is deployed by a processor when deployment criteria are satisfied. The processor may embody a pattern recognition technique for analyzing the measured acceleration and angular motion of the vehicle and determine whether deployment of the occupant protection device is beneficial. For example, the pattern recognition technique may be a neural network trained to determine whether the vehicle is experiencing a crash such as a rollover based on the measured acceleration and angular motion of the vehicle.
