NXP Semiconductors announced its secure connected car V2X RoadLINK chips will be available for the first time from Delphi RoadLink for Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communication using autograde Wi-Fi (IEEE 802.11p). This would enable connected cars to have V2V and V2I features in use on roads in two years.
NXP chips with software from Cohda Wireless allows alerts to cars from cars and infrastructure. Infrastructure includes traffic lights, signage and municipal systems. Data is protected and hacker threats are thwarted by NXP’s V2X hardware security module.
NXP reports that V2X can compliment Advanced Driver Assistance Systems (ADAS) like radar. NXP notes that cellular or other networks can be slow or unreliable therefore the chips use Wi-FI on IEEE 802.11p, (automotive standard). The network “directly connects surrounding infrastructure and vehicles to each other to achieve immediate transmission and ensure reliable road safety communications. ”
The NXP RoadLINK product range for the connected car enables cars to communicate wirelessly with each other and with traffic infrastructure, exchanging data such as location, speed and direction. Therefore the RoadLINK offers 360-degree driver awareness. The chip models are TEF510x and SAF5100. They are available to OEMs and Tier1s manufacturers through Delphi.
The chips meet Japanese 760Mz C2X requirements, US and European (5.9GHz) as well as Wi-Fi and DSRC (5.8GHz) specifications.
NXP also offers hardware security modules (HSM) and verification acceleration to protect the connected car against hacking or data theft.
