Method of operating an adjustable roll stabilizer

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.
