Vayyar has announced what the company claims to be the world’s first sensor solution capable of meeting industry dual-band needs.

Developed specifically to increase safety and passenger monitoring in the interior of a car, the solution provides manufacturers with sensors that meets country-specific frequency requirements, such as an 79GHz band in Japan, or a 60GHz band in Europe and the United States. Addressing these regulatory bands provides new flexibility to manufacturers and tier 1 suppliers by offering a choice between these frequencies.

By 2022, child presence detection will be a requirement through the HOT CARS Act legislation in the USA and the Euro NCAP. Vayyar’s universal sensor solutions create a new, holistic solution for manufacturers to maximize in-cabin safety and prevent hot car deaths. These sensors are able to detect if an infant has been left in a vehicle, even if they are covered by a blanket or in a car seat, and send a notification to a driver’s phone to alert them of the danger. The sensor’s point cloud capabilities are able to display the dimension, shape, location and movement of people and objects, and enable the complete identification of the car’s environment - regardless of environmental conditions like darkness.

In-cabin safety solutions include seat belt reminders (SBR), optimized airbag deployment, gesture control, driver drowsiness alerts and Child Occupancy and Detection (COPD) alarms. Vayyar’s RF sensor on a chip (ROC) has 48 transceivers at 60 GHz and 79 GHz wide-bands, allowing over thousands of virtual channels. The chip also consists of an internal DSP for real-time signal processing saving the need for an external ECU. This dual-band solution is easily integrated into existing automotive framework, and offers multi-function capabilities to reduce the overall cost and number of sensors needed for a vehicle.
