Introduction to Automated Vehicle Safety: Multi-Agent, Functional Safety, and SOTIF

Fatal accidents involving automated vehicles have made it clear that safety is paramount to their acceptance, testing, verification, validation, and deployment. In fact, safety has been ranked as the number one concern for the acceptance and adoption of automated vehicles, and understandably so, since safety has some of the most complex requirements in the development of such vehicles. However, there are many misconceptions involving safety and the concept of safety as applied to automated vehicles.

This 12-hour course will help characterize the nature of safety and the fundamental technology needed by most people involved in the design, development, testing, operation, and deployment of automated vehicles. The course will enable participants to envision a future where the safety of automated vehicles is well understood and will guide all stakeholders in the development and use of safe automated vehicles. You'll learn the main attributes of safety as applied to automated vehicles, including the three types of safety: Functional Safety, Safety of the Intended Functionality (SOTIF), and Multi-agent Safety. The discussion will enable participants to conceive of the various applicable design aspects of safety, clarify the role of SOTIF and multi-agent safety for automated vehicles, and address the development of multi-agent safety using a probabilistic and stochastic framework.

Five practice exercises are incorporated into the course requirements to ensure application and retention. Learners will complete the exercises between live sessions, and each assignment should take an average of one hour outside of scheduled class time.
