In-Vehicle Infrastructure

Building a dynamic and secure foundation for software-defined vehicles

Creating software-defined vehicles requires evolving the vehicle technology stack. At the network level, Ethernet and IP have emerged as the foundation of next-generation in-vehicle networks—though CAN networks will co-exist for many years. 5G will not only accelerate vehicle connectivity but also spur rapid growth in real-time hybrid vehicle-cloud applications. And Service Oriented Architectures (SOA) and containerization will usher in a new generation of vehicle software that is flexible and updatable, while in-vehicle automation will enable new features without requiring new software. These technologies are among the key foundational elements of software-defined vehicles that will drive a surge of innovation in the automobile and beyond.

However, the dynamic vehicle environments enabled by these advances also bring new requirements and challenges. In-vehicle networks and cloud connectivity need to be actively managed to ensure optimal performance. Dynamic software updates need to be orchestrated to install easily, quickly, and reliably—without impacting user experience or vehicle safety. And holistic cybersecurity is required to protect against expanding attack surfaces and bad actors. Sonatus has automakers covered with our comprehensive suite of dynamic in-vehicle infrastructure products.
