Automotive Industry Forms Bus Standard Consortium

September 10, 2009

Led by Denso, Freescale, and TRW, the new organization will drive development and deployment of the Distributed System Interface standard. With its establishment, the consortium unveils the next-generation DSI 2.5 standard.

TOKYO /PRNewswire-FirstCall/ -- Denso Corp., Freescale Semiconductor, and TRW Automotive Holdings Corp. have established an industry consortium on September 8 to drive further development and deployment of the Distributed Systems Interface (DSI) standard.

The consortium will actively seek broader industry participation to enhance the capability of bus systems while also expanding the range of applications beyond automotive and into industrial control and networking. Consortium members will be free to use the DSI standard and will be able to influence the development of future generations of the DSI standard.

With the establishment of this consortium, the members expect acceleration in the development of advanced, competitive DSI standards that have higher performances and lower costs, as well as help expand the DSI standard in the market.

With this announcement, the DSI Consortium unveils DSI 2.5, the next-generation standard. The consortium will also work to develop the DSI 3.0, which will aim to increase bus performance, such as electromagnetic compatibility signature and transmission speed.

The DSI protocol has been adopted by the world's leading supplemental restraint system airbag manufacturers. Currently, more than a dozen automotive OEMs have included DSI-based systems in their vehicles. DSI-compliant products have been in production for many years. Demand for airbag-related systems is driven by legislation, consumer influences, and automotive growth in emerging markets.

As automotive airbag systems continue to become more sophisticated and require more collision detection sensors, car manufacturers face pressures to reduce cost while enhancing safety. The consortium will enable implementers of the DSI safety bus to participate in the evolution of the standard and to continue providing robust, high-speed communications for the growing number of collision sensors planned to be used in new vehicles.
