AVFI: Fault Injection for Autonomous Vehicles
Autonomous vehicle (AV) technology is rapidly becoming a reality on U.S.
roads, offering the promise of improvements in traffic management, safety, and
the comfort and efficiency of vehicular travel. With this increasing popularity
and ubiquitous deployment, resilience has become a critical requirement for
public acceptance and adoption. Recent studies into the resilience of AVs have
shown that though the AV systems are improving over time, they have not reached
human levels of automation. Prior work in this area has studied the safety and
resilience of individual components of the AV system (e.g., testing of neural
networks powering the perception function). However, methods for holistic
end-to-end resilience assessment of AV systems are still non-existent.Comment: Published in: 2018 48th Annual IEEE/IFIP International Conference on

ML-based Fault Injection for Autonomous Vehicles: A Case for Bayesian Fault Injection
The safety and resilience of fully autonomous vehicles (AVs) are of
significant concern, as exemplified by several headline-making accidents. While
AV development today involves verification, validation, and testing, end-to-end
assessment of AV systems under accidental faults in realistic driving scenarios
has been largely unexplored. This paper presents DriveFI, a machine
learning-based fault injection engine, which can mine situations and faults
that maximally impact AV safety, as demonstrated on two industry-grade AV
technology stacks (from NVIDIA and Baidu). For example, DriveFI found 561
safety-critical faults in less than 4 hours. In comparison, random injection
experiments executed over several weeks could not find any safety-critical
faultsComment: Accepted at 2019 49th Annual IEEE/IFIP International Conference on
