V2X chipset improves road safety

To alert drivers about potentially hazardous traffic situations even beyond the line of sight, Delphi’s platform uses NXP’s technology combined with application software from Cohda Wireless. This complements advanced driver assistance systems, allowing alerts to be delivered to vehicles from other cars and surrounding infrastructure, such as traffic lights and signage. Alongside traffic signals or signage indicators, messages could include blind-intersection collision, road condition hazards, road works, presence of emergency vehicles, stationary or slow moving vehicles, traffic jams and accident warnings. Operating on IEEE 802.11p, the platform avoids cellular or other networks that can be slow or unreliable. To achieve immediate transmission and ensure reliable road safety communications, the platform directly connects surrounding infrastructure and vehicles to each other. NXP’s V2X hardware security module protects the V2X communication against illegal attacks or data theft. 

The RoadLINK chipset includes the EF510x and SAF5100, which are available to OEMs and Tier1s and meet Japanese 760Mz C2X requirements, as well as US and European (5.9GHz), WiFi and DSRC (5.8GHz) specifications.

Torsten Lehmann, Senior Vice President and General Manager, NXP Semiconductors, commented: “The fact that Delphi has selected NXP as semiconductor supplier for its V2X communication technology makes us very proud. It underpins our strong commitment to make this life-saving technology a reality and proves our technology leadership in semiconductors for the secure connected car. It is also yet another milestone in our long-lasting close collaboration with Delphi.”

"The ability to detect and warn drivers of danger ahead is a significant leap toward improving car safety and traffic management,” added Jeff Owens, Chief Technology Officer, Delphi Automotive.
