CEVA, In , the leading licensor of wireless connectivity and smart sensing technologies and co-creation solutions, announced that its RivieraWaves ultra-wideband (UWB) IP has been extended to support UWB-Radar for Child Presence Detection (CPD) as specified by Euro-NCAP and similar specifications in other regions.
CEVA technical experts will be available to discuss its UWB Radar solution at embedded world 2023, March 14-16, in Nuremburg, Germany. Visit CEVA’s booth #3A-611 at the show to meet the CEVA team and interact with the latest wireless connectivity and smart sensing technology demos on display.

Child Presence Detection is a safety system designed to detect and alert if a child or pet is accidently left behind in the vehicle. In Europe, Euro NCAP is actively promoting CPD through its safety rating metrics. In China, CNCAP is similarly promoting CPD and in the U.S. the Hot Cars Act has passed, and the NHTSA is reviewing CPD guidance. In-cabin radar based on UWB is proving to be an excellent technology solution for presence sensing, capable of detecting even micro movements right down to breathing rate. Using UWB radar sensors rather than alternative camera-based sensors also addresses the privacy concerns of in-cabin sensing systems, as well as supports low-light operation. Furthermore, by reusing the Secure Digital Key UWB anchor points which are increasingly common in automobiles, UWB-based CPD can be economically deployed across the automotive market spectrum, from premium to budget.
The CEVA UWB Radar solution is an add-on software package to the CEVA RivieraWaves UWB PHY and MAC IP. The solution delivers robust Breath Per Minute (bpm) detection for CPD with less than 1bpm resolution, exceeding the Euro NCAP requirements. Leveraging a coherent demodulation architecture and advanced ranging algorithms, the CEVA RivieraWaves UWB with Radar delivers excellent distance and angle measurements in the complex in-cabin environment, enabling gesture recognition and intruder alarm features. The solution can be optimized for different environments, including a configurable number of antennas. Designed for coexistence with the Car Connectivity Consortium® (CCC) Digital Key, the solution permits reuse of Digital Key UWB anchor hardware.
