“…This section presents results for both injected faults on our VILAD testbed. For each fault, figures 11 and 12 show the longitudinal commands applied to the car's actuators (acceleration and brake) in three cases: (1) the nominal case, (2) with the specified injected fault and no Safety-Bag, (3) with the specified injected fault in presence of a Safety-Bag. The difference in the applied commands between (2) and (3) is due to safety actions taken by the Safety-Bag after a safety rule has been identified as violated.…”

This work presents a study to improve the safety of experimental autonomous vehicles in the Heudiasyc laboratory. This work presents risk analyses showing that the use of our vehicles involves significant risks during experiments, and that integrating an Independent Safety Component called Safety-Bag in the vehicle architecture can significantly reduce these risks. The Safety-Bag carries out the on-line verification of safety necessities by checking the vehicle's current state with safety rules and taking or disabling actions to ensure a safe behavior. In our work, we present and we apply two methods for risk analysis (FMEA and HazOp-UML) to design these safety necessities in the case of experimental autonomous vehicles. We also present the validation of two safety necessities through fault injection experiments with a robotized Fluence vehicle and a vehicle in the loop testbed.

An adaptive observer design for denial‐of‐service attack detection in platoon

Due to the increasing demand for autonomous driving, cyber-attacks detection nowadays receives significant attention. Among several different types of attacks, Denial-of-Service (DoS) attacks can consume resources and cause the system under attack to stop responding, which can be considered a time delay model affecting the response of the attacked system. To detect the possible DoS attacks in Cooperative Adaptive Cruise Control platoon model, an adaptive observer design is proposed in this paper, where the time delay caused by DoS attacks can be fast and accurately estimated. To highlight the performance of the proposed adaptive observer, numerical simulations are applied and the performance is compared against the sliding mode observer in terms of the DoS attack time delay estimation convergence and accuracy.
