  • Patent number: 11618297
    Abstract: A method of operating an adjustable roll stabilizer for a motor vehicle. The stabilizer has an actuator which can be rotated through a system angle about a rotational axis to apply a system torque and rotate two stabilizer sections relative to one another about the axis. The stabilizer sections are coupled at a radial distance from the axis to a respective wheel suspension, and depending on the system angle and under the external influence of movements of the wheel suspensions, twist relative to one another through a stabilizer angle. In the context of a perturbation magnitude regulation, the actuator is controlled based on the stabilizer angle determined from height levels of the wheels, by virtue of a stored relationship for the roll stabilizer and/or motor vehicle. The plausibility of the stored relationship between the wheel height levels and the stabilizer angle is checked by a model calculation.

  • Patent number: 11560035
    Abstract: 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.

  • Patent number: 11518208
    Abstract: A method of operating an adjustable roll stabilizer (1) of a motor vehicle. The adjustable roll stabilizer (1) has an actuator (2) which can be rotated through a system angle (?) relative to a rotational axis (3) in order to twist two stabilizer sections (6a, 6b), connected thereto, relative to one another. The stabilizer sections (6a, 6b) are each a radial spaced away from the rotational axis (3) and each is coupled to a wheel suspension (7a, 7b, 8a, 8b, 9a, 9b). The method includes controlling the actuator with a field-orientated regulator (20) as a function of input signals which include at least a target motor torque (21), and checking the control of the actuator (2), brought about by the field-orientated regulator (20), for plausibility independently of the field-orientated regulator (20).

  • Patent number: 11511593
    Abstract: A method of operating an adjustable roll stabilizer (1) of a motor vehicle. The adjustable roll stabilizer (1) includes an actuator (2) which can rotate relative to a rotational axis (3) in order to twist two stabilizer sections (6a, 6b) connected thereto relative to one another about the rotational axis (3). The stabilizer sections (6a, 6b) are radially spaced away from the rotational axis (3) and each is coupled to a wheel suspension (7a, 7b, 8a, 8b, 9a, 9b). The actuator (2) 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 (?) that is acceptable for the motor vehicle.
