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.

Method of operating an adjustable roll stabilizer

A method of operating an adjustable roll stabilizer () of a motor vehicle. The adjustable roll stabilizer () includes an actuator () which can rotate relative to a rotational axis () in order to twist two stabilizer sections () connected thereto relative to one another about the rotational axis (). The stabilizer sections () are radially spaced away from the rotational axis () and each is coupled to a wheel suspension (). The actuator () is controlled on the basis of a system target torque specified for the vehicle, and the specified system target torque is tested for acceptability in relation to a roll torque distribution (&#x3b2;) that is acceptable for the motor vehicle.
