Device and Method for Stabilizing a Motor Vehicle
First Claim
1. A device for stabilizing a vehicle, having a detection device (10) which is provided for determining an actual value (xact) of a lateral dynamics variable which describes the lateral dynamics of the vehicle, and having an evaluation unit (11) which determines a setpoint value (xset) for the lateral dynamics variable and limits said setpoint value to a limit value (xlimit) which is determined as a function of a prescribed stability condition if it is found that the magnitude of the setpoint value (xset) of the lateral dynamics variable exceeds the magnitude of the determined limit value (xlimit), with the evaluation unit (11) actuating vehicle assemblies (12), which are provided for influencing the longitudinal and/or lateral dynamics of the vehicle, as a function of a comparison of the determined actual value (xact) and the determined and possibly limited setpoint value (xset) of the lateral dynamics variable in such a way that the driving stability of the vehicle is increased, characterized in that the lateral dynamics variable comprises a tilting angle variable (φ
- ) which describes a tilting angle (φ
) of the vehicle, and/or a slip angle variable (α
) which describes a slip angle (α
) which occurs on a vehicle wheel.

Abstract
The invention relates to a device and a method for stabilizing a vehicle, having a detection device (10) which is provided for determining an actual value of a lateral dynamics variable which describes the lateral dynamics of the vehicle, and having an evaluation unit (11) which determines a setpoint value for the lateral dynamics variable and limits said setpoint value to a limit value which is determined as a function of a prescribed stability condition if it is found that the magnitude of the setpoint value of the lateral dynamics variable exceeds the magnitude of the determined limit value, with the evaluation unit (11) actuating vehicle assemblies (12), which are provided for influencing the longitudinal and/or lateral dynamics of the vehicle, as a function of a comparison of the determined actual value and the determined and possibly limited setpoint value of the lateral dynamics variable in such a way that the driving stability of the vehicle is increased. In this case, the lateral dynamics variable comprises a tilting angle variable which describes a tilting angle of the vehicle, and/or a slip angle variable which describes a slip angle which occurs on a vehicle wheel.

12. A method for stabilizing a vehicle, in which an actual value (xact) of a lateral dynamics variable which describes the lateral dynamics of the vehicle is determined, and in which a setpoint value (xset) for the lateral dynamics variable is determined and limited to a limit value (xlimit) which is determined as a function of a prescribed stability condition if it is established that the magnitude of the setpoint value (xset) of the lateral dynamics variable exceeds the magnitude of the determined limit value (xlimit), with the longitudinal and/or lateral dynamics of the vehicle being influenced as a function of a comparison of the determined actual value (xact) and the determined and possibly limited setpoint value (xset) of the lateral dynamics variable in such a way that the driving stability of the vehicle is increased, characterized in that the lateral dynamics variable comprises a tilting angle variable (φ
