Abstract
A vehicle rollover sensor is provided for detecting an anticipated overturn condition of a vehicle. The rollover sensor includes a first angular rate sensor sensing attitude rate of change of a vehicle about a first axis and producing a first attitude rate of change signal. Also included is a second angular rate sensor sensing attitude rate of change of the vehicle about a second axis and producing a second attitude rate of change signal. The first and second angular rate sensors are located on a vehicle and arranged so that the first axis is different from the second axis. The rollover sensor further includes a rollover discrimination controller for determining a vehicle overturn condition based on the first and second sensed attitude rate of change signals. In addition, roll arming logic generates a roll arming signal based on the first and second sensed attitude rate of change signals.
