Abstract
Latest generations of automobiles are gradually being equipped with technologies that have increasing automation, a trend which had led to increase in the system complexity as well as increased human-automation interactions. Failures in such complex human-automation interactions increasingly occur due to the mismatch between what operators know about the system and what the designers expect operators to know. Causes of road accidents also change due to role shift of drivers from controlling the vehicle to monitoring the in-vehicle controllers. Failures in such complex systems involving human-automation interactions increasingly occur due to the emergent behaviours from the interactions, and are less likely due to reliability of individual components. Traditional safety analysis methods fall short in identifying such emergent failures. This paper focuses on using a systems thinking inspired safety analysis method called System Theoretic Process Analysis (STPA) to identify potential failures. The analysis focuses on a SAE Level-4 Vehicle that is in the development phase, and is controlled partially by a safety driver and its built-in Autonomous Driving System (ADS). The analysis yields that while increase in complexity does increase system functionality, it also brings a challenge to evaluate the safety of the system and potentially causes incorrect human-automation interactions, leading to an accident. After the possible inadequate driver-vehicle interactions are identified by STPA, corresponding requirements were then proposed in order to avoid the unsafe behaviour and thus preventing the hazards.
