Abstract
A method and system of activating a safety device of a vehicle having x, y and z-axes. The method includes generating a y-acceleration signal representative of the acceleration of the vehicle in the y-axis, generating an angular-rate signal representative of the angular velocity of the vehicle with respect to the x-axis, calculating a vehicle angle having a relationship to the angular-rate signal and being representative of the angle of the vehicle about the x-axis, determining an angular-rate threshold having a relationship to the vehicle angle and the y-acceleration signal, comparing the angular-rate signal to the angular-rate threshold, and activating a safety device when the magnitude of the angular-rate signal is greater than the angular-rate threshold.
