A revolution is expected on the automotive computing systems, driven by the demand of complex functionalities, high performance, and efficient resource utilisation towards automated driving. This poses significant challenges on timing predictability and reliability, which are critical to ensure safety of the vehicles. The standard dominating the automotive industry for two decades, AUTOSAR Classic, which emphasises guarantee on the worst-case timing behaviour and deploys conservative methodologies of static task configuration, resource isolation, as well as memory protection, is evolving to AUTOSAR Adaptive, whose core is dynamic resource sharing on multiprocessor systems. This talk presents the safety challenges for futuristic automotive computing systems and reports the pioneer works along this direction, which bridge the gap between resource sharing and reliability.
