Tata Elxsi develops ECU for hybrid electric vehicle

Tata Elxsi 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 Hybrid Electric Vehicle 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.

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.

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 power-train. Without Tata Elxsi's technology and excellent cooperation, this 'Brain' unit could not have been realized.”

Speaking on the development, Anil Sondur, Vice President, Tata Elxsi commented, We are happy that we have been able to support Fuji Heavy Industries, who is our esteemed customer in a successful production programme. For Tata Elxsi, this is a moment of great pride to see our end-to-end technical and engineering capability being utilized and deployed in the market by a reputed car company like Subaru. We look forward to a greater relationship in the coming years with Fuji Heavy Industires.”
