Volkswagen announced the rollout of its new Golf equipped with NXP’s life-saving RoadLINK® V2X communication solution. The already-popular Golf is lauded as Europe’s biggest selling car. The new model aspires to bring even more smart, connected features that should make its fans even more happy – and safe and connected.
Using V2X that’s Wi-Fi-p based (also called DSRC or 802.11p), cars can “talk” to other cars, motorcycles, emergency vehicles, traffic lights, digital road signs, and pedestrians –independent of car brands and without the support of cellular infrastructure.
You’ll start seeing the VW Golfs on Europe’s roads as early as December. Already 1,000 km of European roads are equipped with V2X technology based on Wi-Fi – and that’s set to more than quadruple with 5,000 km planned through the end of 2019.
V2X extends what your car can “see” – up to a mile away and around obstacles
Many new cars on the road today are loaded with advanced safety systems that can “see” what’s around you, exposing blind spots and nearby hazards. Featuring radar, LiDAR and camera technology, these cars automatically steer and brake you to safety if you’re slow or unable to react.
V2X complements other existing ADAS technology, allowing your car to “see” even further than what’s nearby, around curves, around other vehicles, through the dense urban environment, and even up to a mile away.
With V2X, your car is alerted to what’s hidden from sight far ahead, around corners and over hills, detecting and warning you in real-time of other vehicles, road works, traffic congestion and even people – long before radar sensors or vision systems would have detected the hazards.
How Wi-Fi-p V2X works
As two or more things enabled with V2X come into range, they form an ad-hoc wireless network based on the DSRC (dedicated short-range communications) 802.11p standard. Unlike cellular-based V2X that requires assistance of a cellular network, the DSRC communications allow them to automatically transmit and send real-time short, dedicated safety-critical messages to each other. Furthermore, Wi-Fi is only safe and secure V2X technology that has been tested for more than 10 years and is ready for immediate volume rollout.
V2X communication is set to become a critical part of advanced driving assistance systems and the migration to autonomous cars that communicate with each other and with traffic infrastructure. The unique benefit of Wi-Fi-based V2X is its robust, low latency, real-time communication – regardless of any car brands.
C-ITS support for Wi-Fi-based V2X technology
Just last week, a growing ecosystem of supporters for Cooperative Intelligent Transport Systems (C-ITS) signed a statement of support for WiFi-based V2X with the primary goal: increase road safety and decrease congestion. C-ITS includes wireless technology for connected vehicles, road infrastructure, pedestrians, bicyclists, motorcyclists, agriculture machinery and railway equipment that share and use information for coordinating their actions in public spaces.
