V2X Connectivity with ROS for AD Applications

2021-04-06
2021-01-0060
Sensors like camera, Lidar and Radar will help to perceive the surroundings, exposing nearby objects and blind spots within the line of sight. With V2X connectivity, vehicles communicate to other vehicles and infrastructure using wireless communications even in non-line of sight conditions. ...This paper presents an approach to utilize a V2X system to develop Automated Driving (AD) features in a Robot Operating System (ROS) environment. ...This was achieved by developing ROS drivers and creating custom messages to enable the communication between the V2X system and vehicle sensors. The developed algorithms were tested on FEV’s Smart Vehicle Demonstrator.

Early adopters of the V2X technology can experience the benefits of enhanced V2X market penetration. The outcome of adopting this concept will result in an inflated V2X market penetration rate leading to earlier safety, mobility, and situational awareness improvements. ...This paper presents the computer vision-based V2X collaborative perception. Our system uses a forward-looking camera in the host vehicle. The camera detects road users such as pedestrians, vehicles, and motorcycles. ...The outcome of adopting this concept will result in an inflated V2X market penetration rate leading to earlier safety, mobility, and situational awareness improvements.

Physics-Based Misbehavior Detection System for V2X Communications

2022-03-04
Abstract Vehicle to Everything (V2X) allows vehicles, pedestrians, and infrastructure to share information for the purpose of preventing accidents, enhancing road safety, and improving the efficiency and energy consumption of transportation. ...Although V2X messages are authenticated, their content is not validated. Sensor errors or adversarial attacks can cause messages to be perturbed and, therefore, increase the likelihood of traffic jams, compromise the decision process of other vehicles, or provoke fatal crashes. ...In this article, we introduce V2X Core Anomaly Detection System (VCADS), a system based on the theory presented in [1] and built for the fields provided in the periodic messages shared across vehicles (i.e., Basic Safety Messages, BSMs).

Pseudonym Issuing Strategies for Privacy-Preserving V2X Communication

2020-08-18
Abstract Connected vehicle technology consisting of Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communication falls under the umbrella of V2X, or Vehicle-to-Everything, communication. This enables vehicles and infrastructure to exchange safety-related information to enable smarter, safer roads. ...To this end, the Security Credential Management System (SCMS) and Cooperative Intelligent Transportation Systems (C-ITS) Credential Management System (CCMS) have been proposed to enable authentication and authorization of V2X messages without compromising individual user privacy. This is accomplished by issuing each vehicle a large set of “pseudonyms,” unrelated to any real-world identity.
