The Impact of SOMEIP in Modern Automotive Networks

Originating from BMW, SOME/IP addresses the need to configure complex modern vehicle networks with a scalable and flexible approach. SOME/IP stands for Scalable Service-Oriented Middleware over IP. It is a layer 3 command and control API designed to facilitate communication between various electronic control units (ECUs) within a vehicle.


By operating over TCP, SOME/IP ensures reliable data transmission, distinguishing it from other protocols like AVB/TSN, which operate at layer 2.

Key Features of SOME/IP

Device Discovery and Configuration

SOME/IP simplifies the discovery and configuration of devices over automotive Ethernet. This capability is important for managing the increasing number of ECUs in modern vehicles.

Integration with AUTOSAR

SOME/IP is a published specification within the AUTOSAR (Automotive Open System Architecture) domain. This standardization allows for compatibility and interoperability across different manufacturers and suppliers. SOME/IP is generally available in all OS implementations.

Excelfore’s Approach to SOME/IP

Excelfore has developed an efficient, low-footprint, and portable “C only” implementation of SOME/IP tailored to meet the specific needs of automotive manufacturers and suppliers. It supports several automotive OSs, e.g., Linux, QNX, Integrity, and FreeRTOS. Excelfore’s SOME/IP solution is highly suitable for microcontrollers (MCUs) and lower-class devices. Customers are provided with sample applications, complete API documentation, and a library for their integration.

In contrast, V-SOME/IP, the open-source implementation for Linux, is bulkier, which can impact performance and response times. This efficiency is crucial for modern automotive systems where resources are often constrained.

Deployment and Usage

Excelfore’s SOME/IP solutions have been deployed with several original equipment manufacturers (OEMs) worldwide. Our API and SOME/IP library have been in use for over four years, demonstrating performance and reliability in real-world applications.

By leveraging our efficient SOME/IP implementation, automotive manufacturers can ensure seamless communication and control across their vehicle networks, driving innovation and enhancing overall vehicle performance.

The Evolution of In Vehicle Networks: From CAN to Automotive Ethernet

Image
As vehicles become increasingly complex and connected, the evolution of in vehicle networks has become a critical factor in enabling advanced automotive technologies. From the early days of the Controller Area Network (CAN) to the emergence of Automotive Ethernet, the journey of in vehicle network development reflects the growing demand for higher data rates, real-time communication, and integration of sophisticated systems like Ethernet TSN and IP camera software. The Foundation: Controller Area Network (CAN) Introduced in the 1980s, the Controller Area Network (CAN) was a groundbreaking innovation that revolutionized in-vehicle communication. CAN allows different systems—such as engine management, transmission, and safety systems—to communicate without needing a central computer, enabling reliable communication among various electronic control units (ECUs) in a vehicle. This network protocol provided the reliability and efficiency required for the first generation of digital veh...
