Automotive Technology Evolution: Probing the Future of Next Generation In-Vehicle Networking

What factors drive the advancement in in-vehicle networking?

The major catalyst behind the revolution in the automotive technology is increasing consumer demand for enhanced in-car experience, which includes optimised driver-assistance systems, infotainment, and robust connectivity. These demands compel car manufacturers to integrate comprehensive networking systems. The rise of autonomous vehicles also signifies a shift towards greater interconnectivity, requiring high-speed, reliable data transmission within vehicles.

What is the technological transformation in in-vehicle networking?

Over time, the in-vehicle network, primarily based on controller area network (CAN) bus, has evolved to include Local Interconnect Network (LIN), FlexRay, and recently, Ethernet. These enhancements have produced robust, fault-tolerant, high-speed data dissemination capacities, paving the way for innovative applications like telematics, advanced driver-assistance systems (ADAS), infotainment, etc.

What are the expectations for the future of in-vehicle networking?

In keeping pace with technology advancements and consumer needs, the automotive industry is now trailing towards secure, intelligent, and connected vehicles. We can anticipate the introduction of 5G and vehicle-to-everything (V2X) technology, paving the way for enhanced vehicle safety, improved traffic management, and autonomous driving. The growing trend of electric vehicles will also necessitate refined in-car networks, as their complex ecosystems need superior intra-vehicle data cascading.
