Audi has announced that they are now offering a new feature on their Audi A8 luxury sedan models, predictive active suspension.
This new predictive active suspension is designed to offer supreme ride comfort of a chauffeur-driven limousine or the firm handling of a sports car, and you can choose what settings you want.
Predictive active suspension in the Audi A8 is a fully active suspension system. Its electromechanical actuators adjust the suspension. They can lift up or force down each of the luxury sedan’s wheels individually, to actively manage the body’s ride height in every situation. The active suspension can lift or lower the body by up to 85 millimeters (3.3 in) from its central position at all four corners within five-tenths of a second.
There are compact electric motors located close to each of the Audi A8’s wheels, running off the car’s 48-volt primary electrical system and governed by power electronics. A belt drive and a compact harmonic drive step up the electric motor’s torque almost 200-fold to 1,100 Nm (811.3 lb-ft) and apply it to a steel rotary tube. The latter is permanently attached to a preloaded titanium rod located inside it and capable of turning through more than 20 degrees. From the end of the rotary tube, the force is transmitted to the suspension via a lever and coupling rod – at the front suspension it acts on the spring strut, and at the rear suspension on the transverse link.
