Active roll compensation

Active roll compensation with electromechanical anti-roll bars. The adaptive roll compensation is a new development. It is referred to as “electromechanical active roll stabilisation” (“eAWS”) on the basis of its structural design. The most important components of eAWS are the anti-roll bars at the front and rear axle. Conventional running gear set-ups are equipped with a steel anti-roll bar at the front and rear that stretches from one side of the axle to the other. The two sides of the anti-roll bar twist against each other when cornering (or when driving over larger bumps on only one side of the vehicle). The kinematics cause the roll angle of the car to be reduced when cornering. This works even more efficiently with “eAWS” active roll stabilisation. To extend the limits of driving physics, the Touareg is equipped with eAWS and has electromechanical anti-roll bars at the front and rear axle. A central control unit coordinates its use. In this case, the two sides of the relevant anti-roll bar are connected via a control motor. Depending on the driving situation, the two halves of the anti-roll bar are either twisted against each other (stiffened) or decoupled using an electric motor. The high voltage (48-V) required to activate the powerful electric motors is briefly established using so-called “Super Cabs” (capacity accumulators). The lean of the Touareg is significantly reduced due to the active anti-roll bars. Directional stability is also increased significantly on roads where one side is uneven. On rougher terrain, the interlacing of the axles and therefore the traction can be improved thanks to the electromechanical decoupling of the anti-roll bars.
