ABSTRACT:
The invention relates to a method for redundantly estimating, i.e. by various sub-methods, the risk of lateral overturn of a vehicle. One sub-method involves estimating the risk of overturn according to the actual braking state of the vehicle—braking or strong braking, or not braking or slight braking—by monitoring the rotational speed behavior of the wheels on the inside of the turn. Another sub-method involves pre-calculating the rolling motion of the vehicle about the longitudinal axis thereof over a short time span of, for example, 0.5 s to 1.5 s on the basis of instantaneous movement parameters and assessing the risk of overturn on the basis of the anticipated rolling motion.
