1. A roll over determining method comprising:
- a turning mode determining step for determining whether or not a vehicle is turning;
a roll rate determining step for determining whether or not the roll rate of the vehicle exceeds a predetermined value; and
a roll over determining step for determining whether or not the vehicle is in a roll over state,wherein if it is determined in said turning mode determining step that the vehicle is turning and it is determined in said roll rate determining step that the roll rate exceeds the predetermined value, the determining of said roll over determining step is executed on the basis of the relationship between a sideways acceleration of the vehicle and a roll angle of the vehicle.

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.

12. A roll over determining method comprising:
-
a roll rate detecting step for detecting a roll rate of a vehicle; a roll angle detecting step for detecting a roll angle of the vehicle; a sideways acceleration detecting step for detecting a sideways acceleration of the vehicle; a roll rate determining step for determining whether or not the roll rate exceeds a predetermined value; a turning mode determining step for determining whether or not the vehicle is turning; and a roll over determining step for determining whether or not the vehicle is in a roll over state, wherein, if it is determined in said turning mode determining step that the vehicle is turning, and it is determined in said roll rate determining step that the roll rate exceeds the predetermined value, the determining of said roll over determining step is executed on the basis of the relationship between the sideways acceleration of the vehicle and the roll angle of the vehicle, and wherein, if it is determined in said turning mode determining step that the vehicle is not turning, then the determining of said roll over determining step is executed on the basis of the relationship between the roll rate and the roll angle. - View Dependent Claims (13)
