Abstract
A rollover determining apparatus and methods for determining whether a vehicle is about to roll over distinguishes a type of rollover that is likely to occur to the vehicle based on the lateral acceleration of the vehicle and the roll angle of the vehicle. Moreover, a determination is made whether the state of the vehicle indicated by a first quantity corresponding to the distinguished type of rollover is in a rollover region determined by a predetermined threshold line. The apparatus and methods can also change the threshold line in accordance with the magnitude of second quantity that is different from the first quantity and that corresponds to the distinguished type of rollover.
