Abstract:
1. An apparatus for detecting a rollover of a vehicle, comprising: a roll angular velocity detector periodically detecting a roll angular velocity of the vehicle at intervals; a memory unit memorizing values of the roll angular velocity periodically detected by the roll angular velocity detector; a predictive angular velocity calculator calculating a predictive value of the roll angular velocity to be expected after an elapse of a predetermined period of time on the basis of a present value and a past value of the roll angular velocity memorized in the memory unit; and a rollover prediction unit predicting whether or not there is a possibility that the vehicle will make a rollover, on the basis of the predictive value of the roll angular velocity, and one of: a value of the roll angle of the vehicle and a predictive value of the roll angle to be expected after the elapse of the predetermined period of time.
