1. A method for stabilizing a vehicle, wherein the vehicle comprises a roll stabilizer which is configured to stabilize a first axle and a second axle of the vehicle as a function of a roll torque distribution between the first axle and the second axle, and the method comprising:
a determination step of determining a sideslip angle index from a difference between a calculated transverse acceleration, which is calculated from a measured yaw rate of the vehicle and a measured speed of the vehicle, and a detected transverse acceleration of the vehicle, and the sideslip angle index is related to a sideslip angle of the vehicle, and
a generating step of generating a control signal using the sideslip angle index, and the roll torque distribution of the roll stabilizer is adjusted, by the control signal, directly as a function of the determined sideslip angle index.
