FRANKFURT, Germany – TRW Automotive Holdings Corp. has announced its second generation Safety Domain ECU (SDE 2) which can integrate data from multiple driver assist system, chassis and suspension functions in one unit. The second generation SDE will offer greater performance when compared to its previous generation and will be a key technology in supporting semi-automated driving and car2car communication.

Dr. Hans-Gerd Krekels, portfolio and engineering director, TRW Global Integrated Electronics commented: “In previous years we have seen exponential growth in electronic systems in cars – a trend that is set to continue with the further penetration in active safety systems and increasingly automated driving functions. As the number of sensors increases in a vehicle, having a central safety ‘domain’ helps to deal with the increase in complexity and to simplify the electronic architecture.”

TRW’s SDE 2 has a flexible, open architecture structure to integrate software control algorithms from both suppliers and third parties including vehicle manufacturers, using AUTOSAR 4.0 and beyond as a basis. As a scalable technology, it can integrate and process data from multiple functions including vehicle dynamics arbitration and driver assist data (radar, video camera and digital map information), to enable 360 degree environmental sensing. It has a high performance multi-core microprocessor that in addition to interfacing on CAN or FLEXRAY, can support Ethernet communication for high speed, high volume data transfer.

Krekels continued: “TRW’s SDE 2 uses leading edge electronics technology to support next generation vehicle requirements. We are continuously looking at how we can integrate a wider range of features into this single unit and enable a higher degree of functionality and actuator control.

“In order to achieve the necessary high level of performance, we can integrate performance micros originally designed for automotive graphics applications as well as the Mobileye chip from our video camera sensors, directly embedded within the SDE.”

TRW anticipates that its SDE 2 will be ready for production by 2017. The first generation technology started production this month with a major European vehicle manufacturer.
