Introduction to SOME/IP in Automotive AUTOSAR using Raspberry Pi 4

July 25, 2023

In the rapidly evolving automotive industry, advancements in data and autonomy technologies have paved the way for high data transmission and complex communications. To address the limitations of traditional signal-based communications, service-oriented architectures have emerged as a promising solution. In this video, we will explore the world of SOME/IP (Scalable service-Oriented MiddlewarE over IP) and its role in enabling seamless communication within vehicles.

Introducing SOME/IP

SOME/IP, first introduced by BMW in 2011, is a middleware designed to facilitate transactions independent of underlying hardware layers. While not entirely new, it has gained significant traction in recent years, especially after AutoSAR specified it clearly in their November release. This inclusion brought about major changes and upgrades to the SOME/IP specifications, including the crucial aspect of Service Discovery.

The Significance of Service Discovery

One of the defining features of service-oriented architectures is Service Discovery. It empowers endpoints to discover what services are offered by other endpoints within the network. This dynamic process establishes a runtime contract between a service provider and a consumer Electronic Control Unit (ECU). By creating this seamless connection, ECUs can effectively communicate and utilize each other’s services, ensuring a smooth flow of data and information.

Empowering the Future: Zonal Architectures and Software Defined Vehicles

The need for service-oriented communication has been driven by advancements in zonal architectures and software-defined vehicles. These new paradigms require a flexible and scalable communication framework, making service-oriented architectures the preferred choice for automakers and OEMs. Embracing this approach opens up new possibilities, including Over-The-Air (OTA) updates for vehicles post-production. Thanks to technologies like SOME/IP, vehicles can receive timely updates, enhancing their capabilities and ensuring a future-ready automotive ecosystem.

Intrepid Control Systems: Enabling YOUR SOME/IP Journey

Intrepid Control Systems, a pioneer in the automotive communication solutions domain, offers cutting-edge products and solutions for SOME/IP. Two of their flagship products, Vehicle Spy X and neoVI, house their own SOME/IP service discovery stacks, making them invaluable assets for testing architectures reliant on SOME/IP.

  • neoVI Pi – Your Profiling and Running Platform: neoVI Pi is a remarkable device housing a Raspberry Pi and Intrepid’s CAN or CAN FD interface hardware. Running on Linux, this device, along with a media converter and a switch, forms an ideal platform for architecting SOME/IP within an Electronic Control Unit (ECU)
  • Vehicle Spy X – Unleashing the Potential: Vehicle Spy X is a cross-platform, modern, and feature-rich BUS analyzer. Its python interface provides easy access to Intrepid’s own service discovery stack. Notably, Vehicle Spy X also incorporates an AutoSAR stack, facilitating seamless communication network testing.

As automotive technology propels forward, service-oriented architectures and SOME/IP play a pivotal role in revolutionizing communication within vehicles. The ability to dynamically discover and utilize services between ECUs creates a future-ready, flexible ecosystem that aligns with the demands of zonal architectures and software-defined vehicles. Intrepid Control Systems, with its innovative products and unwavering commitment, continues to drive the evolution of automotive communication technology. Embrace the power of SOME/IP and service-oriented architectures today to shape the vehicles of tomorrow.
