Siemens is at ADAS & Autonomous Vehicle Technology Expo explaining how the SOTIF standard brings a shift in the safety case for the introduction of ADAS and autonomous vehicles. It says the standard requires suppliers to have methods in place to reduce the number of unknown unsafe scenarios by applying sufficient exploration and testing. The challenge is to have an objective, robust and scalable process to generate as many of these scenarios as possible, considering the variability of static and dynamic components. Simply put: the more scenarios that can be evaluated up front, the safer the system becomes.
In response, Siemens has developed the Critical Scenario Creation proprietary methodology. It systematically and automatically generates a pool of scenarios for a specific operational domain based on a map of the scene and recorded data. Critical Scenario Creation gives an objective indication of the severity of the risk, with a severity indicator that combines a KPI for criticality with a proprietary KPI for novelty. This normalized severity value essentially provides an objective indication of exactly how unsafe and unknown a scenario is.
“Where the SOTIF standard requires developers to explore unsafe unknown scenarios, Siemens is currently the only company to provide a patented solution that is a methodological approach to identify scenarios that haven’t been recorded,” explained Martijn Schut, product manager, Siemens. “It deviates from common practice where the behavior of actors in a known safe scenario is changed to create a known unsafe scenario (an actor-focused approach), by focusing on the scene and all possible routes of all possible actors in time. The unique approach allows for discovering unknown unsafe scenarios more easily and thus at lower costs.”
The new CSC tool can also be used by cities and traffic planners to identify problem areas and consequently design and implement infrastructure that minimizes risk and maximizes safe operations.
“Visitors can also see our leading sensor validation solution, Simcenter Prescan, which features the industry-best physics-based sensors, and our recording solution featuring smart triggering, Simcenter Scaptor,” added Schut.
