Hardware Meets Software: From Classic Mechanical Systems to a Fully Interlinked High-End Control Unit

  • Electronic Chassis Platform interlinks mechanical chassis components
  • Brake energy recuperation turns efficiency into a new chassis dimension
  • Future fusion of chassis and powertrain control in an integrated vehicle dynamics computer
  • New high-end control unit clearly more powerful and about ten times as fast as current systems

Exactly 40 years ago, Audi revolutionized the automotive world. With its permanent quattro all-wheel drive the company, in 1980, presented a new approach to chassis technology that still decisively underpins the slogan “Vorsprung durch Technik.” Today, thanks to smart interlinking by the Electronic Chassis Platform (ECP), innovative chassis systems such as electromechanical Active Roll Stabilization (eAWS), the predictive active suspension and Dynamic All-wheel Steering (DAS) are able to unfold their full potential. In the Audi e-tron, the integrated Brake Control System (iBRS) emphasizes the fact that efficiency will become the third variable in chassis development alongside ride comfort and sportiness. As a high-tech control unit, the future vehicle dynamics computer can simultaneously actuate up to 90 components.
