Abstract: Technologies are provided for detecting anomalous data at runtime in an autonomous vehicle component that is indicative of a byzantine fault, and providing real-time remediation. Input and output data streams of the vehicle component can be analyzed to generate a normal operational model for the vehicle component. Using the model, deviations from a known steady state of operation of the vehicle component can be detected and flagged as potential faults. The vehicle component can then be isolated and/or restarted. Additionally or alternatively, a specification can be defined that specifies allowed component interactions in the autonomous vehicle system. The specification can be used to generate tests that can be used to validate the functional correctness of the vehicle components. The specification can be used at run-time to detect component interactions that are not allowed. Such a disallowed component interaction can be detected using the specification and flagged as a potential fault.

Abstract: In a memory diagnostic method, a fixed domain stores data that are not changed during process execution. A variable domain stores data that are subject to writing during process execution. A fixed domain diagnostic part adds an error-detecting code to data to be stored in the fixed domain. The fixed domain diagnostic part compares an error-detecting code calculated from data read from the fixed domain with the added error-detecting code to determine whether there is any data error. A variable domain diagnostic part temporarily stores data stored in the variable domain in a memory region different from the memory storing the data, and writes known data in the variable domain where the temporarily stored data were stored. The variable domain diagnostic part reads data from the region where the known data were written and determines whether the data is the same as the written known data.
