Automotive systems are safety-critical cyber-physical \ systems. In particular, undesired feature interaction can \ lead to safety-critical behavior. In order to address this \ problem, we investigate physical feature interaction in this \ context using simulation (with more than one physical variable). \ This allows us to visualize both the behavior of features \ in isolation and their interaction. Our major result is \ a new insight about feature coordination. In such a cyber-physical \ context, it can be insufficient to coordinate as usual \ by giving one feature priority over another one. Instead, \ coordinating based on a physical variable involved in the \ feature interaction appears to be both necessary and sufficient. \ In summary, we present our investigation of safety-critical \ feature interactions and their coordination in automotive \ systems using simulation, and its results.
