Abstract

A method for stabilizing a vehicle in particular to prevent overturning, in which a strategy is selected from at least two different strategies as a function of a quantity describing or corresponding to whether an overturn tendency about a vehicle axis oriented in the longitudinal direction of the vehicle exists, and which may be determined at least as a function of a quantity describing or corresponding to the wheel behavior of at least one wheel, and which may also be determined a function of a comparison which is carried out as a function of a quantity describing or corresponding to the lateral dynamics of the vehicle and of a characteristic value that is determined as a function of a quantity describing or corresponding to the instantaneous friction conditions.

Dependent claims

A method for stabilizing a vehicle, the stabilizing including preventing the vehicle from overturning about a vehicle axis oriented in a longitudinal direction of the vehicle, the method comprising the steps of:

(a) performing at least one of the steps of:
(i) determining if an overturn tendency exists for the vehicle;
and
(ii) making a comparison as a function of a quantity corresponding to lateral dynamics of the vehicle and of a characteristic value for the quantity corresponding to the lateral dynamics of the vehicle;
and
(b) selecting a strategy for stabilizing the vehicle to prevent overturning from at least two different strategies as a function of at least one of the steps of determining and making;
and
(c) performing at least one intervention for stabilizing the vehicle based on a selected one of the at least two different strategies, wherein one of the at least one intervention for one of the at least two different strategies is different than another of the at least one intervention for another of the at least two different strategies.
