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.
