Self Study Program 402 – Dynamic Steering in the Audi A4 2008
Self Study Program 402 – Dynamic Steering in the Audi A4 2008 PDF. In the Audi A4’08, dynamic steering is featured for the first time in an Audi vehicle. This steering system eliminates the compromise of having a constant steering ratio. An optimal steering ratio is obtained as a function of driving speed and steering wheel angle. The dynamic steering system provides a suitable steering ratio for every situation – whether parking, driving on windy country roads or at high speed on a motorway.
Over and above this, the dynamic steering system assists the ESP system in specific driving situations by implementing corrective steering inputs which serve to maintain dynamic stability. This intelligent new system, therefore, not only enhances driving and steering comfort, but also provides a marked improvement in active motoring safety.
