A method for stabilizing a vehicle () in which the vehicle () has a roll stabilizer (), which is designed to stabilize a first axle () and a second axle () as a function of a roll torque distribution between the first axle () and the second axle (). The method comprises a step of determining a sideslip angle index from a difference between a transverse acceleration calculated from a yaw rate of the vehicle () and a speed of the vehicle (), and a detected transverse acceleration of the vehicle (). The sideslip angle index is related to a sideslip angle of the vehicle (). The method also comprises a step of generating a control signal () using the sideslip angle index. The control signal () is suitable for adjusting the roll torque distribution of the roll stabilizer () as a function of the determined sideslip angle index.

Method, control device and system for stabilizing a vehicle

A method for the active roll stabilization of a vehicle () by way of a roll stabilizer (). The roll stabilizer () includes a stabilizer rod (), a stabilizer housing () and a stabilizer motor (), arranged inside the stabilizer housing (), so that a first end of the stabilizer rod () is connected at to a wheel () of the vehicle and at a second end thereof is mounted to be rotated by way of the stabilizer motor (). The method including the steps of obtaining a first set-point value of a rod torque of the stabilizer rod (); obtaining a second set-point value of a motor rotation angle of the stabilizer motor (); limiting the second set-point value based on an absolute value and/or a gradient of the first set-point value; and inputting the second set-point value into a control sequence () as a guide magnitude.

Active roll stabilization with improved control by means of a set point limitation

A method for operating an adjustable roll stabilizer for a motor vehicle. The adjustable roll stabilizer has an actuator which relative to a rotational axis can be rotated through a system angle in order to twist two stabilizer sections connected to it about the rotational axis relative to one another. The stabilizer sections are each coupled to a respective wheel suspension at a radial distance away from the rotational axis, and, starting from a target angle to be set at the actuator and having regard to the actual system angle and other parameters of the adjustable roll stabilizer and/or the motor vehicle equipped with it, a position-rotational speed regulator determines a target motor torque on the basis of which a motor of the actuator is controlled, so that having regard to the target angle and the actual system angle, the target motor torque is checked for plausibility.
