Samsung invests in safety-critical Ethernet networks for cars and satellites

The aim of this investment and technology partnership with the Austrian firm is to develop safety-critical networking to in-car systems using the real-time Ethernet implementation.

It is hoped this will lead to open autonomous and ADAS technologies needed for autonomous vehicle systems.

Stefan Poledna, Member of the Board at TTTech, writes:

“The company’s collaborative and flexible technology allows OEMs and Tier-1 suppliers to accelerate the development, integration, and validation of new capabilities in their vehicles.”

TTTech has been working for sometime with Audi developing automated piloted driving systems as used in the zFAS piloted control platform in the 2017 Audi A8.

Deterministic Ethernet refers to a networked communication technology that uses time scheduling to bring deterministic real-time communication to standard IEEE 802 Ethernet. It has the concepts of deterministic and reliable operation using standard components.

From the original development of Time-Triggered Ethernet in 2006 for the NASA Orion spaceship (launched in 2014), time scheduling of Ethernet has been used in a range of aerospace, automotive and industrial applications.

Since 2012, the IEEE Time-Sensitive Networking task group has been standardising the core mechanisms of time scheduling in IEEE 802.1.

Young Sohn, president and chief strategy officer of Samsung Electronics described this as a “seminal moment for Samsung’s automotive business” working with leading OEMs like Audi and TTTech on automotive-safety technology.

“Automotive advances like autonomous controls and advanced driver assistance systems will have a profound impact on society—from transforming urban spaces to bringing mobility to ageing populations,” said Sohn.

But TTTech’s high reliability computer networking systems can also be used in the aerospace sectors, such as in the Boeing 787 Dreamliner and NASA’s Orion spacecraft.

The strategic investment in TTTech is the first investment from Samsung’s recently-announced Samsung Automotive Innovation Fund (SAIF). Samsung has also acquired Harman for $8bn as part of its automotive strategy.

As a Tier 1 supplier Harman will market TTTech’s open safety systems to automotive OEMs.
