Audi AG, has recently completed an extensive field test of NXP and Cohda Wireless vehicle-to-vehicle (V2V) communications technology in Ingolstadt, Germany. In high speed challenges, V2V-enabled Audi vehicles equipped with the NXP RoadLINK™ chipset drove towards one another at relative speeds of up to 500 kilometers per hour, communicating across distances of more than two kilometers.
According to Audi, RoadLINK™ delivered excellent results in the reliability of wireless exchange of warnings, reception performance, and communication range in real traffic conditions and at high speeds. The RoadLINK™ chipset cut reaction time and communicated potential hazards and safety-critical scenarios significantly faster than conventional wireless technology.
The V2V tests represent another significant milestone in the strategic partnership between Audi and NXP. In 2012, NXP and Audi signed a strategic innovation partnership agreement designed to accelerate the speed of automotive innovation and time to market – including V2V communications.
Aurel Papp, head of development EMC / Antenna Components, Audi AG, explains: “The NXP RoadLINK™, chipset combined with the Delphi Automotive roof antenna, delivered the best results so far in our field tests. In challenging test environments, such as intersections in the forest (trees absorb wireless signals at 5.9 GHz), the range was better than the previously tested systems. The results demonstrate the benefit of combining NXP’s RoadLINK™ solutions with the circuit layout and design of the passive antenna emitters by Delphi.”
The field test featured the intelligent roof antenna developed by the automotive supplier, Delphi, based on the NXP and Cohda Wireless RoadLINK™ chipset. An NXP hardware secure element was also used to protect the communications from manipulation and unauthorized tracking or data access.
