Audi has developed the Audi drive select, an innovative system that is used on the new A4 available as an option. It enables the driver to influence operation of the engine, automatic transmission, steering and suspension damping electronically. The main components of Audi drive select are the dynamic steering system, which uses a new type of superposition gear and electronic control of the dampers. In order to put the Audi drive select concept into practice, an infrastructure has been created that permits communication between the participating systems and the coordinating units. Audi drive select is coordinated by a software-module in the car's central body computer control unit. The dynamic steering system is described. Functions are outlined: 1. variable steering ratio, 2. active vehicle stabilisation (operating principle in the event of over steer, operating principle in the event of under steer, braking on road surfaces with different amounts of tyre grip). System layout and components are described: construction of superimposition, hydraulics, electronics. The safety concept is outlined. A description of the new damping control systems is given. In conjunction with Audi drive select, it adds to the car's individual character. The development target was to use sports suspension as a basis for settings with the emphasis on comfort, but with no sacrifices as far as the A4's road dynamics were concerned.
