Legacy AD/ADAS development from OEMs centers around developing functions on
ECUs using services provided by AUTOSAR Classic Platform (CP) to meet
automotive-grade and mass-production requirements. The AUTOSAR CP couples
hardware and software components statically and encounters challenges to
provide sufficient capacities for the processing of high-level intelligent
driving functions, whereas the new platform, AUTOSAR Adaptive Platform (AP) is
designed to support dynamically communication and provide richer services and
function abstractions for those resource-intensive (memory, CPU) applications.
Yet for both platforms, application development and the supporting system
software are still closely coupled together, and this makes application
development and the enhancement less scalable and flexible, resulting in longer
development cycles and slower time-to-market. This paper presents a
multi-layered, service-oriented intelligent driving operating system foundation
(we named it as Digital Foundation Platform) that provides abstractions for
easier adoption of heterogeneous computing hardware. It features a multi-layer
SOA software architecture with each layer providing adaptive service API at
north-bound for application developers. The proposed Digital Foundation
Platform (DFP) has significant advantages of decoupling hardware, operating
system core, middle-ware, functional software and application software
development. It provides SOA at multiple layers and enables application
developers from OEMs, to customize and develop new applications or enhance
existing applications with new features, either in autonomous domain or
intelligent cockpit domain, with great agility, and less code through
re-usability, and thus reduce the time-to-market.Comment: WCX SAE World Congress Experience 202
