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.
Device Discovery and Configuration
SOME/IP simplifies the discovery and configuration of devices over 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.
