ABSTRACT:
A control circuit determines that a vehicle is in a turning mode. A roll rate sensor then detects the roll rate (RR) and determines whether or not the roll rate exceeds a threshold value. If it is determined that the roll rate does exceed the threshold value, then it is determined that the vehicle is in a roll over state if the relationship between the sideways acceleration (Gy) and the roll angle (RA) falls inside the roll over determining area of a determining map stored in advance in the control circuit. Accordingly, the roll over state of the vehicle is detected early.
