Tata Elxsi develops electronic control unit for Subaru hybrid

Tata Elxsi announced that its Automotive Electronics development division has completed the development of an AUTOSAR 3.0-compliant Gateway ECU (Electronic Control Unit) for Subaru, the automobile manufacturing division of Fuji Heavy Industries Ltd. This ECU has now gone into production for Subaru’s new XV Crosstek Hybrid (earlier post) from June 2013.

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 CAN (Controller Area Network) and LIN (Local Interconnect Network) channels and one of the application cores runs Tata Elxsi developed AUTOSAR 3.0 BSW. Tata Elxsi’s Safety Engineers have also ensured that the Gateway ECU is ISO26262 ASIL-C compliant.

Tata Elxsi’s strong experience in AUTOSAR based ECU development coupled with offshore engineering and hardware prototyping to international standards, has enabled Fuji Heavy Industries to achieve a more than 30% reduction in overall development costs.

Tata Elxsi provided the OEM 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. In an on-going relationship, Tata Elxsi continues to support Subaru with software maintenance of the ECU and development of multiple variants of the Gateway ECU.

A part of the $100-billion Tata group, Tata Elxsi addresses the communications, consumer products, healthcare, media and entertainment, semiconductor and transportation sectors.
