Automotive supplier TRW unveiled 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 offers better performance than the previous generation and will play a key role in TRWs semi-automated driving and car2car strategy.

Automotive supplier TRW unveiled 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 offers better performance than the previous generation and will play a key role in TRWs semi-automated driving and car2car strategy.

TRW's SDE 2 features 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 is powered by a multicore microprocessor (which type was not disclosed), which, in addition to interfacing on CAN or Flexray data bus systems, also supports Ethernet communication for high speed, high volume data transfer.

In order to achieve the necessary high level of performance, the TRW design facilitates integrating microprocessors 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, TRW Automotive CEO explained at the Fraunkfurt Motor Show.
