The future for connected cars and autonomous vehicles received a boost at the Geneva International Motor Show 2016 with the announcement by Harman and NXP of their technology collaboration regarding V2X communication.
At the show, Harman demonstrated its LIVS Connected Car Compute Platform for advanced vehicle intelligence with vehicle-to-x capability (V2X) based on RoadLINK technology from NXP Semiconductors. This radio wave-based wireless technology could improve road safety by alerting drivers of critical traffic situations beyond the range of current production sensors, as well as working independently of mobile data networks. V2X can allow drivers to “see” around corners and beyond traffic obstacles ahead, such as large trucks.
The V2X solution demonstrated by Harman and NXP as part of Harman’s Life-Enhancing Intelligent Vehicle Solution (LIVS) automotive compute platform operates on IEEE 802.11p, a wireless communication standard designed for the needs of the automotive industry. The radio-wave bandwidth for this communication protocol has already been reserved for V2X use in both the US and Europe.
V2X directly connects vehicles and the surrounding infrastructure to each other in ad-hoc networks based on proximity to achieve immediate transmission and ensure reliable road safety communications.
With the Harman-NXP collaboration, V2X communication is protected against illegal attacks by NXP's V2X hardware security module and Harman’s comprehensive 5+1 safety architecture with hypervisor and firewall as an indispensable basis for all technologies and services, including OTA (over the air) update capabilities. The V2X application software runs on the i.MX 6Solo applications processor from NXP – a feature and performance-scalable platform.
V2X technology is crucial for autonomous vehicles, enabling hazard detection and car-to-car communication beyond the line of sight, even in difficult weather conditions, thus complementing advanced driver assistance systems (ADAs) like radar or cameras. Messages sent from vehicle to vehicle and from street furniture to vehicle can include blind-intersection collisions, road condition hazards, road works, presence of emergency vehicles, stationary or slow moving vehicles, traffic jams and accident warnings, as well as traffic signals or signage indicators.
“Harman leads the industry as an end-to-end system integrator for automakers and technology suppliers to provide drivers intelligent, adaptable and predictive solutions in the car. We are proud to collaborate with NXP for a flexible and secure V2X solution as part of our leading compute platform to dramatically improve not only safety, but comfort and convenience,” said Phil Eyler, president of Harman’s Connected Car Division.
“From easing traffic congestion to improving fuel efficiency, Harman is seamlessly integrating V2X capabilities into our connected car solutions for the benefit of automakers and drivers alike”.
“We are very pleased that Harman has selected NXP RoadLINK for their connected car compute platform, recognizing the reliability, performance and long range of our communications technology,” said Torsten Lehmann, senior vice president for car infotainment and driver assistance at NXP.
“This is another major milestone in NXP’s strategy to make traffic safer, smoother and cleaner, avoiding accidents and saving lives. NXP V2X chipsets will be on the road later this year in first OEM series cars.”
Harman demonstrated its range of connected car technology on the Rinspeed stand at the Geneva show, using a fully equipped technology concept car centred around a remodeled BMW i8.
