Overview

The Sonatus Zonal Architecture Solution is a transformative in-vehicle networking platform designed to accelerate the transition towards Software-Defined Vehicles (SDVs). It replaces traditional domain-based architectures with a centralized, zonal network framework, allowing automakers to manage vehicle communication more efficiently, reduce cabling complexity, and optimize resource allocation. Leveraging Software-Defined Networking (SDN) principles, it delivers dynamic configuration, enhanced reliability, and scalability while supporting mixed-critical systems and advanced in-vehicle applications. This architecture simplifies integration, improves system maintainability, and accelerates feature deployment across the entire vehicle lifecycle.

Features and Capabilities

• **Dynamic Configuration: **Utilizes the 802.1DG TSN Profile for Automotive to enable real-time adjustments, ensuring optimal network performance, seamless integration of new applications, and minimal downtime during system updates.
• **Network Monitoring: **Provides comprehensive visualization and diagnostic tools for traffic flows, latency, and error detection. Supports proactive maintenance, performance optimization, and early identification of potential network bottlenecks.
• **Service-Oriented Architecture (SOA) Management: **Integrates applications across vehicle zones, enabling service discovery, fine-grained access control, and monitoring. Streamlines communication between ECUs and software services, enhancing security and system coordination.
• **Over-the-Air (OTA) Update Framework: **Supports reliable, secure software distribution across all in-vehicle networks, including Ethernet and CAN ECUs. Facilitates continuous feature updates, bug fixes, and security patches without physical intervention.
• **Scalability and Flexibility: **Designed to adapt to growing vehicle complexity, supporting increasing numbers of ECUs and software applications while reducing overall hardware dependencies and cabling requirements.
• **Reliability and Safety: **Incorporates redundancy, fault tolerance, and safety-critical interlocks to maintain operational integrity of essential systems, ensuring compliance with automotive safety standards.
• **Lifecycle Support: **Enables manufacturers to efficiently manage the full lifecycle of vehicle networks—from initial design and testing to deployment, updates, and end-of-life decommissioning—while reducing engineering effort and time-to-market.
