The global leader in 4D imaging radar Vayyar has announced the multi-range XRR chip, the latest addition to their automotive safety sensors. It is claimed to be the world’s first single RFIC (Radio Frequency Integrated Circuit) with an immense range of up to 300 meters. The MIMO (Multiple-In Multiple-Out) single-chip comes with an array of 48 transceivers with on-chip processing. With unprecedented resolution provided by its 4D point-cloud imaging, Vayyar’s XRR chip is perfect for use in passenger cars, trucks and motorcycles.
“Vayyar’s XRR chip delivers unparalleled multi-range capability, reducing complexity and costs, so that high-end safety is accessible and affordable for all vehicle models,” said Ian Podkamien, VP and Head of Automotive at Vayyar. “To achieve this, we integrated 48 transceivers into a single chip, along with the computing power necessary for optimal performance, while maintaining cost-efficiency and a compact form factor.”
Vayyar’s XRR chip makes use of radio frequency technology to map an environment. The 79 GHz single-chip 4D imaging radar sensor covers large areas to reduce the number of sensors in vehicles.
Talking about the competitors, there are several other companies that are also in the race of developing such 4D radar modules. SteradianSemi, a company based in India, offers E-band 256 channel MIMO Radar Module. Another one is RFISee, an Israel based company that is developing a 4D imaging radar chip that generates real-time 3D location and velocity and maps the cars’ surrounding objects.
A Look at Some Capabilities of Vayyar’s XRR Chip
The XRR chip features an ultra-wide Field of View which enables full coverage of vehicle surroundings.. The multi-range RFIC supports dozens of Advanced Driver Assistance Systems (ADAS), Advanced Rider Assistance Systems (ARAS), and autonomy capabilities on a single-chip platform, providing unmatched multifunctionality. It offers an immense advantage over alternatives. Conventional Lidar systems make use of optics, which are severely disadvantaged by rain, snow, fog or dust. On the other side, conventional 2D Radars are robust but provide a poor resolution and narrow Field of View. Vayyar’s XRR chip takes the best of both these worlds and puts it in a single, affordable package with a small form factor package.
“We believe our sensors will create a shift in the way the automotive industry will use radar in the future. We look forward to working with our partners to increase passenger safety worldwide,” Podkamien adds.
Safety Features Provided by the Multi-range Chip
Vayyar’s high-performance XRR chip boasts a range of up to 300m. It can identify obstacles such as dividers, curbs, parked vehicles, moving vehicles and other hazards. In low-speed environments like parking lots, the chip can detect pedestrians and provide parking assistance using its uSRR (ultra Short Range Radar) and SRR (Short Range Radar) sensing. When in an open and speedy environment like the highway, Vayyar’s XRR chip facilitates applications such as Lane Change Assist (LCA), Adaptive Cruise Control (ACC), Blind Spot Detection (BSD), Collision Warnings (fCW/rCW), Cross Traffic Alerting (CTA) and Autonomous Emergency Braking (AEB).
Two XRR chips, one in front of the car and one at the back, can cover almost 360 degrees around the car. So, just two sensors do more work than the 20+ conventional sensors like infrared, Lidar, camera, ultrasonic and more. This makes the Vayyar’s XRR chip a low cost and comprehensive all-in-one solution. The company also claims that just two XRR chips can earn any vehicle 33 Euro NCAP safety points. Vayyar’s platform supports nine different Euro NCAP ADAS requirements for 2023, protecting pedestrians, cyclists and motorcyclists while maximizing safety ratings.
