Method for stabilizing the driving behavior of a tractor-trailer combination and vehicle movement dynamics control device
First Claim
1. A method for stabilizing the driving behavior of a tractor-trailer combination (1) comprising a plurality of vehicles, the method comprising the steps ofobtaining a tilting inclination variable;
- anddetermining a tilting limit (16) on the basis of the tilting inclination variable;
prescribing the tilting limit to a vehicle movement dynamics control system acting on at least one of a drivetrain or brakes of the tractor-trailer combination (1) to prevent tilting inclination by selective control interventions into an engine management system or a drive of a tractor (2) or by selective actuation of brake cylinders (5),wherein a respective individual tilting inclination variable is determined at a plurality of vehicles of the tractor-trailer combination (1), and a value (18) of the tilting inclination variable which is decisive for the determination of the tilting limit (16) is selected from the respective individual tilting inclination variables.

Abstract
In a method for stabilizing the driving behavior of a tractor-trailer combination, a tilting inclination variable is obtained and a tilting limit is determined on the basis of the tilting inclination variable and is prescribed to a vehicle movement dynamics control system. A vehicle movement dynamics control device carries out the method. In order to improve the stabilization of the driving behavior of tractor-trailer combinations with different loads of the individual vehicles, the respective tilting inclination variable is determined at a plurality of vehicles of the tractor-trailer combination, and the value of the tilting inclination variable for the determination of the tilting limit which is decisive for the determination of the tilting limit is obtained from the tilting inclination variables.
