Problems solved by technology

Furthermore, some components influencing the system stiffness are subject to aging phenomena which affect the system stiffness during the operational service life of the adjustable roll stabilizer
In methods such as those described above for roll stabilization, assumed values ​​for the system stiffness are incorporated into the actuation of the actuators, so that deviations from the actual system stiffness lead to erroneous adjustments to the actuators. or at least non-ideal manipulation

Embodiment Construction

[0023] To demonstrate the field of application of the invention, figure 1 First, the adjustable roll stabilizer 1 is shown in a schematic illustration. The adjustable roll stabilizer 1 is part of a not completely shown chassis of a (not shown) motor vehicle. The reference numerals designate only the vehicle structure 10 of the motor vehicle. The roll stabilizer 1 is also part of an axle of a motor vehicle, for example the front and / or rear axle of a motor vehicle may be equipped with an adjustable roll stabilizer 1 .

[0024] Such as figure 1As shown, the left wheel 7 a and the right wheel 7 b arranged on the opposite vehicle side are each connected to the vehicle structure 10 via a steering mechanism 8 a or 8 b , not explained in detail. Thus, the wheel 7a and the steering mechanism 8a or the wheel 7b and the steering mechanism 8b each constitute a unit and are each coupled to the associated stabilizer section 7a or 7b of the adjustable roll stabilizer 1 by means of a pivo...

Abstract

A method for roll stabilization of a motor vehicle by means of an adjustable roll stabilizer (1), in which the adjustable roll stabilizer (1) has an actuator (2) which is operable to rotate two stabilizer sections (6a, 6b) connected to the actuator relative to each other about an axis of rotation (3). According to the invention, the actuator (2) is actuated depending on at least one system setpoint moment, taking into account the system stiffness of the roll stabilizer (1), and a comparison between the current system moment and the system setpoint moment is carried out in order to check and / oradapt the correctness of the stored system stiffness.

Description

technical field [0001] The invention relates to a method and a system for roll stabilization of a motor vehicle by means of an adjustable roll stabilizer. Background technique [0002] It is known from motor vehicle technology, in particular chassis technology, to influence the rollover or rolling behavior of a motor vehicle by means of so-called roll stabilizers. In the basic structure, the roll stabilizer is here a substantially C-shaped torsion bar spring, which is rotatably mounted in the central region relative to the vehicle structure and whose opposite outer ends are connected by means of coupling elements (so-called swing struts) and are correspondingly coupled to the wheel suspension. With this construction, the roll stabilizer ensures that the body of the vehicle not only presses down on the outside side of the bend (due to centrifugal force) when cornering, but also ensures that the wheels on the inside of the bend are slightly lowered. Roll stabilizers increase...
