Critical Scenario Creation framework for AV development

The introduction of the SOTIF (Safety of the Intended Functionality) standard has brought a fundamental shift in the safety case for higher autonomous vehicles (AVs). The main challenge for autonomous vehicle system development to meet the SOTIF standard is to have a robust and scalable way to automatically generate unknown-unsafe scenarios and evaluate the system under test in such scenarios. The more scenarios that can be evaluated, the lesser the impact of the unknown-unsafe scenarios on system safety.

Patented Critical Scenario Creation framework as a service

Our Critical Scenario Creation methodology is a proprietary and patented methodology that systematically and automatically generates unsafe-unknown scenarios for a specific operational design domain based on a map of that scene and recorded data. We've developed a severity indicator to measure criticality, combining a criticality KPI with a proprietary KPI for novelty. The combination of these two generates a normalized severity value which indicates how unsafe and unknown a scenario is for the vehicle under test.

Benefits of Critical Scenario Creation for AV development

By adopting and implementing the Critical Scenario Creation process, automotive OEMs and autonomous vehicle (AV) suppliers can have a methodology to generate unknown-unsafe scenarios derived from the Safety of the Intended Functionality (SOTIF) standards automatically.
