Abstract

A method for stabilizing a vehicle to avoid at least one of a vehicle rolling over about a vehicle axis oriented in the longitudinal direction of the vehicle and the vehicle sliding in the transverse direction. The method determines at least one of a torsion variable that corresponds to how the vehicle behaves in reaction to a force acting on the vehicle about the vehicle axis oriented in the vehicle's longitudinal direction, and a load-shift variable that corresponds to how the vehicle load behaves in reaction to a force acting upon the vehicle. The method determines a vehicle speed and also determines at least one threshold value for the vehicle speed based on the torsion variable and the load-shift variable. The vehicle speed and the at least one threshold value are then compared, and interventions (or measures) are taken to stabilize the vehicle based on the comparison.
