In the context of vehicle architecture, external elements can refer to extended systems outside the vehicle that can influence its function. It is crucial to take into account the necessary interfaces of the function(s) with backend solutions, cloud services, and other vehicles. This consideration guarantees the integrity of the function in a specific context. An Interface Control Document should be accessible. Furthermore, pertinent documentation for Functional Safety (ISO 26252-1-12, 2018), cybersecurity, and Safety of the Intended Functionality (ISO/SAE 21434, 2021) can bolster safety and cybersecurity analyses.
Main Question
Are the architectural aspects between function and other “external elements” considered?
Sub-Questions
- Is the interface to back-end, cloud services and other vehicles considered?
- Is security and integrity of the architectural interfaces considered?
