Audi: Determining the effect of signal errors on the complete vehicle level

The number of different control unit functions and their interactions is continuously increasing. The large number of sources and possibilities of errors makes it more difficult to determine the effect of faulty input signals on the complete vehicle level.

Simulation is one way of managing the increasing degree of connectivity of functions. What is more, simulation can also be used to perform automated parameter studies that identify critical fault and driving conditions more quickly, and it helps to obtain a better understanding of the overall system. In a joint project with AUDI AG, the DYNA4 simulation framework was adapted to this application case.

Benefits and results

  • Investment protection
    Common use of different, already existing vehicle and driver models which are seamlessly integrated in DYNA4.
  • Secure and efficient
    Automated parameter studies ensure extremely efficient testing of the effect of faulty input signals on the behavior of software components in different driving situations.
  • Wide range of applications
    Integration into the database offers extensive opportunities for simulation control and evaluation of results. Thousands of simulations are automatically performed, saved, and subsequently evaluated every day.
  • Very easy to use
    An adapted user interface makes it easier for users to control complex processes.
