1. A method for detecting a tendency of a vehicle to roll over about a vehicle axis, the vehicle axis being oriented in a longitudinal direction of the vehicle, the method comprising the steps of:

  • (a) determining, for at least one wheel, a variable describing a wheel rpm;

    (b) determining at least one variable representing transverse dynamics of the vehicle;

    (c) determining, for the at least one wheel, a variable describing quantitatively a wheel behavior, the variable describing quantitatively the wheel behavior being a function of (1) the variable describing the wheel rpm for a corresponding wheel of the at least one wheel and (2) the at least one variable representing the transverse dynamics of the vehicle; and

    (d) determining whether the vehicle has the tendency to roll over about the vehicle axis as a function of at least the variable describing quantitatively the wheel behavior of at least one of the at least one wheel.
