How ethernet will save the connected car

Mobility is a given in today’s hyper-connected world. This is especially true in cars where, at least in the U.S. – the second largest automobile market – workers average 200 hours annually driving to and from work. In China, the largest automobile market globally, the comparable figure is roughly double that of the U.S.

However, there’s a problem – the “digital backbone” in the connected car is struggling to keep up. And the automotive industry is looking to Ethernet to make that happen.

According to Frost & Sullivan, cars will have anywhere between 10 to100 Ethernet ports by 2020. The lower end will be typical of entry-level cars and luxury cars at the high end of the spectrum. Automakers are adopting Ethernet for two reason. One, the economies of scale to be gained by adopting a standardized communications backbone, and, two, to accommodate the continually increasing connectivity and bandwidth needs in the connected car.

The New Face of Automotive Buses
Automotive buses were originally developed for engine control. Today, they struggle to support the capacity and performance requirements of a growing number of drivetrain, safety, communication and infotainment systems within the car. To address these constraints and support future developments, most of the leading automotive manufacturers already look to Ethernet as the basis for their next-gen automotive buses.
