When you hear people refer to cars as “data centers on wheels,” they’re usually thinking about how an individual experiences enhanced digital capabilities in a car, such as streaming media on-demand or new software-defined services for enhancing the driving experience.
But there’s an important implication lurking behind the statement. For cars to take on tasks that require data center-like versatility, they need to be built like data centers. Automakers in conjunction with hardware makers and software developers are going to have to develop a portfolio of highly specialized technologies that work together, based around similar architectural concepts, to deliver the capabilities needed for the software-defined vehicle while at the same time keeping power and cost to a minimum. It’s not an easy balancing act.
Which brings us to the emergence of a new category of products for the zonal architecture, specifically zonal and the associated automotive central Ethernet switches. Today’s car networks are built around domain localized networks: speakers, video screens and other infotainment devices link to the infotainment ECU, while powertrain and brakes are part of the body domain, and ADAS domain is based on the sensors and high-performance processors. Bandwidth and security can be form-fitted to the application.
