How They Did It - An Analysis of Emission Defeat Devices in Modern Automobiles

Explore an in-depth analysis of emission defeat devices in modern automobiles in this 21-minute IEEE conference talk. Delve into the technical aspects of software defeat devices used by Volkswagen Group and Fiat Chrysler Automobiles to pass emissions tests in the US and Europe. Learn about the development of new static analysis firmware forensics techniques for automatically identifying and confirming the function of known defeat devices. Discover the precise conditions used by firmware to detect test cycles and their impact on engine behavior. Gain insights into the testing of approximately 900 firmware images, with potential defeat devices detected in over 400 spanning eight years. Examine the technical challenges faced by regulators and the important research agenda for providing focused software assurance in the presence of adversarial manufacturers. Cover topics including Dieselgate, tradeoffs in testing and driving, emission limits, acoustic functions, white areas, acceptance profiles, thermal imagers, parallel logics, NSC, emissions testing, portable emissions measurement, and compliance testing.
