Abstract:
A rollover detection apparatus for detecting an anticipated overturn condition for a vehicle, said rollover detection apparatus comprising:an angular rate sensor for sensing attitude rate of change of a vehicle and producing an angular rate signal indicative thereof; a controller comprising an integrator for integrating the sensed angular rate signal and producing an attitude angle, said controller further comprising deployment logic for comparing the attitude angle and sensed angular rate with a variable threshold defining a region of deployment and a region of no deployment, wherein the deployment logic further detects the presence of a driving event which causes at least one of a large attitude rate and a large attitude angle and adjusts the variable threshold based on detecting the driving event so as to prevent deployment of a vehicle overturn condition signal; and an output for providing a vehicle overturn condition signal based on said comparison.
