Abstract: An apparatus for determining a rollover condition of a vehicle may include: a rate sensing unit configured to sense one or more rates of a pitch rate PitchRate and a yaw rate YawRate of a vehicle and a roll rate RollRate_IN; an acceleration sensing unit configured to sense horizontal acceleration and vertical acceleration of the vehicle; a conversion unit configured to convert the horizontal acceleration and vertical acceleration into a pitch rate PitchRate_ACC and a yaw rate YawRate_ACC; a combination unit configured to calculate a pitch rate PitchRate_IN and a yaw rate YawRate_IN by combining the one or more rates with the pitch rate PitchRate_ACC and the yaw rate YawRate_ACC; and a determination unit configured to calculate a roll angle RollAngle, and determine whether the vehicle has rolled over, based on the roll rate RollRate_IN and the roll angle RollAngle.
