Tata Elxsi develops ECU for Subaru HEV

Tata Elxsi has announced that its automotive electronics development division has completed the development of an Autosar 3.0 compliant gateway electronic control unit (ECU) for Subaru, the automobile manufacturing division of Fuji Heavy Industries.
This ECU has now gone into production for Subaru’s new hybrid electric vehicle from June 2013. Fuji Heavy Industries said it awarded the electronic product development contract to Tata Elxsi based on its track record and work experience for Autosar-compliant electronics development.
The scope of work involved development of an ECU on a dual-core microcontroller, which helps control the inter-bus communication necessary to pass information between multiple communication networks within the vehicle. This included complete hardware & software development, hardware-software integration and system level testing. This gateway ECU has multiple controller area network (CAN) and local interconnect network (LIN) channels and one of the application cores runs Tata Elxsi developed Autosar 3.0 BSW. The gateway ECU is also ISO26262 ASIL-C compliant.
Tata Elxsi’s experience in Autosar-based ECU development, coupled with offshore engineering and hardware prototyping to international standards, has enabled Fuji Heavy Industries to achieve more than a 30% reduction in overall development costs. Tata Elxsi provided the OEM with the flexibility to add/modify the requirements during the program and also designed the hardware, which was provided to the EMS vendor for mass production. Tata Elxsi will continue to support Subaru with software maintenance of the ECU and development of multiple variants of the gateway ECU.
Masaru Kurihara, Fuji Heavy Industries, said “This ECU is not a simple gateway. One core is almost Autosar indeed, but another core is filled with our sophisticated model-based software which manages the whole hybrid powertrain. Without Tata Elxsi's technology and excellent cooperation, this brain unit could not have been realized.”
