NXP Semiconductors and Hitachi Solutions collaborate on secure DSRC-based V2X Solution for Japanese market
NXP Semiconductors N.V. and Hitachi Solutions, Ltd. announced a partnership to develop a new V2X solution targeted at the Japanese market [J-ITS]. The solution will employ an NXP developed V2X modem and processor and a full Hitachi Solutions V2X software stack, intending to provide automakers targeting the Japanese market with a head start in the development of their own V2X solutions, whether they are on board units (OBUs) or full Telematics Modules. The solution’s ability to address 5.9 GHz and 760 MHz V2X implementations means that other markets, such as those in Europe and the U.S., could be addressed with a single, reusable design that would offer savings in automotive development costs.
To address expensive pre-development challenges, Hitachi Solutions and NXP partnered to provide developers for the Japanese automotive market with a flexible DSRC-based V2X solution. The partnership will combine NXP’s V2X chipset and Hitachi Solutions’ V2X software stack in a solution that supports V2X implementations in the EU, U.S., and Korea (5.9 GHz) as well as Japan (760 MHz).
As part of the cooperation with Hitachi Solutions, NXP will implement the SAF5400, claimed to be the world's first automotive qualified, high-performance single-chip DSRC modem that also supports Japan (760 MHz). Its scalable architecture and features, such as fast startup time, long range, dual digital antenna diversity, and leading-edge software defined radio (SDR) technologies, offer car makers flexible options for global V2X adoption and field upgradeability.
The secure V2X single-chip modem incorporates NXP's SDR technology that supports different regional standards with a single hardware solution. This integration reduces development, qualification, and maintenance efforts and eases the challenges of global V2X rollouts. The modem includes a hardware engine for secure verification of incoming messages. The ultra-compact, single chip integration of analog RF with digital baseband processing provides a flexible architecture for different processor options.
The NXP and Hitachi Solutions V2X solution will be available in Japan by 2019 and additional markets of Europe and North America soon after. Hitachi Solutions says it will support all layers above the SAF5400 firmware including network, facilities, and application. NXP and Hitachi Solutions also say they will offer Japan-based technical support as well as corresponding support in North America and Europe after additional rollouts.
“We believe this solution will be the best choice for automakers targeting Japanese and global V2X market,” said Hideji Morita, Vice President and Executive Officer, Hitachi Solutions. “Hitachi Solutions is happy to partner with NXP to offer our mutual customers the V2X solution with our robust software stack and NXP’s ground breaking V2X technology.”
“We are pleased to collaborate with Hitachi Solutions on a solution that will enable developers in the Japanese auto market to develop the next generation of V2X for Japan and beyond,” said Patrick Morgan, VP & GM Product Line ADAS Modems, NXP.
