Vayyar 4D Imaging Radar Sensor Set to Revolutionise Automotive Safety

  • Vayyar 4D imaging radar sensor platform addresses multiple challenging safety requirements, providing unprecedented life-saving functionality for all car models.
  • Overcrowded with sensors – average cars forecast to have over 200 by 2030 
  • Single multifunctional radar-on-chip (ROC) able to replace numerous traditional one-function sensors, reducing complexity for both in-cabin and ADAS applications.
  • Leading-edge technology minimizes risk and integration costs, and is set to save car manufacturers and suppliers hundreds of millions of dollars each year.
  • Vayyar’s in-cabin 4D imaging radar sensor provides exceptional resolution and an ultra-wide field of view for precise classification of complete vehicle environment.
  • Production-ready, affordable and scalable solution, proven to automotive grade, supports addition of future safety features via over-the-air (OTA) software upgrades. 

TEL AVIV, Israel – [December 15, 2020] – Vayyar, the global leader in 4D imaging radar sensor technology, is transforming automotive safety with its production-ready Radar-on-Chip (RoC) platform, which enables OEMs to achieve leading-edge vehicle safety while achieving unprecedented cost efficiencies. 

Vayyar’s automotive-grade, AEC-Q100 qualified RoC is a game-changing solution. The chip features up to 48 transceivers, an internal digital signal processor (DSP) and microcontroller unit (MCU) for real-time signal processing. Capable of seeing through objects and able to operate effectively in all weather conditions, Vayyar’s single-chip 4D imaging radar sensor solution can replace over a dozen other sensors and negates the need for expensive LIDAR and cameras.

Multifunctional imaging radar sensor technology

Within the cabin, one multifunctional Vayyar chip can support a multitude of systems, including intruder alerts, Child Presence Detection, enhanced Seat Belt Reminders and eCall to alert emergency services in the event of a crash. It delivers a revolutionary level of safety, utterly unobtainable with traditional single-function sensors.

This breakthrough solution fulfils the functions of multiple chips by sensing, computing, processing, mapping and imaging targets with just a single radio-frequency integrated circuit (RFIC). The platform supports Vayyar’s mission to ensure that safety is available and affordable for all car manufacturers and their key suppliers, at a time when modern cars are becoming increasingly crowded with sensors. 

Today, there are more than 100 sensors in a typical car, with analysts predicting that this will double by 2030. However, Vayyar’s new production-ready RoC offers unprecedented potential and a unique opportunity to cut cost and complexity while improving safety. 

“By replacing multiple sensors with our multifunctional, scalable platform, the possibilities for simplicity and savings are substantial. In addition, regulations and standards are rising and to achieve five-star ratings, automakers are moving away from traditional solutions,” explains Ian Podkamien, Head of Automotive at Vayyar. “Our multi-award winning technology, recognised by organisations such as CLEPA, equips vehicles with the instincts to save lives, providing uncompromising and affordable safety. What’s more, its price point is similar to a single-function 3×4 2D/3D radar solution, but with substantial added value.” 

The platform provides exceptionally high resolution and an extremely wide field of view to deliver unsurpassed precision and detail. The robust sensor is also engineered for scalability, seamlessly facilitating the deployment of emerging features via over-the-air (OTA) software updates. This effectively future-proofs vehicles as new safety requirements and standards emerge.

Central to the platform’s potential is its ability to reduce complexity, in order to cut direct and indirect costs. Vayyar has the in-house expertise to deliver a full end-to-end solution, including hardware, software, development and testing resources, streamlining the integration process for Tier 1 suppliers and OEMs to minimise effort, costs and risk.  

By providing a high-performance, cost-effective and multifunctional sensor, Vayyar’s technology closes the gap between rising safety demands and feasible tech adoption, ensuring that affordable, uncompromising safety is available to all.

About Vayyar Imaging (Automotive)

Vayyar’s intelligent sensors create holistic safety opportunities for in-cabin and ADAS, using automotive-grade 4D imaging radar sensor technology. At the core of these sensors is a high-performance Radar-on-Chip that supports up to 48 transceivers for exceptional resolution. With an ultra-wide field of view, Vayyar’s 60GHz and 79GHz single-chip radar modules cover large areas to reduce the number of sensors in vehicles. They provide comprehensive detection in and around the vehicle, while simultaneously tracking multiple targets and objects. Vayyar technology is multi-functional, affordable and available for mass production. The radar-based platform is robust in all road conditions, while protecting user privacy. Vayyar plans to continue developing the next generation of sensor technology that is miniature, affordable and versatile enough to enable a safer world.

Editor’s notes 

Unlike traditional radar solutions that are based around 2 to 3 transmitting antennas and 3 to 4 receiving antennas, 4D imaging radar leverages a Multiple Input Multiple Output 48-antenna array for high-resolution mapping of its surroundings. The rich point cloud data output combined with an ultra-wide azimuth-elevation field of view, delivers detection and tracking with pinpoint accuracy, making it the ultimate safety sensor for the road ahead.
