NXP Semiconductors N.V one of the largest supplier of automotive semiconductors and Hitachi Solutions, a leader in V2X software platforms for the Japanese automotive market, have 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, providing automakers that target 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 5.9GHz and 760MHz V2X implementations means that other markets, such as those in Europe and the United States, could be addressed with a single, reusable design, offering savings in automotive development costs.

V2X technology allows vehicles to “see” around corners and communicate with other cars and infrastructure. It is instrumental in safety critical applications such as platooning and emergency braking and delivers low latency for real-time communication. The technology also operates in a range that exceeds one mile, even in areas where cellular network connections are not available. Providing vehicles with V2X capability requires extensive and costly electronic pre-development work. To meet this need, carmakers have a choice between developing the foundation for these technologies in-house or working with innovative companies to source pre-made solutions.

To address these expensive pre-development challenges, Hitachi Solutions and NXP have 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 is capable of supporting V2X implementations in the EU, US and Korea (5.9GHz) as well as Japan (760MHz).

As part of the cooperation with Hitachi Solutions, NXP will implement the SAF5400, the world’s first automotive qualified, high-performance single-chip DSRC modem that also supports Japan (760MHz). Its unique scalable architecture, industry leading 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. SAF5400 is the 2nd generation of the only global V2X solution and has been proven on the road since 2017.

The secure V2X single-chip modem incorporates NXP’s Software Defined Radio technology, which provides customers with a platform that supports different regional standards with a single hardware solution. This integration reduces development, qualification and maintenance efforts significantly 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, dependent on the need of the customer.

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 will support all layers above the SAF5400 firmware including network, facilities and application. NXP and Hitachi Solutions will offer strong Japan-based technical support as well as corresponding support in North America and Europe after additional rollouts.
