According to the National Safety Council, even if it's just 57 degrees outside, the temperature inside a car can quickly hit 110 degrees. A child's body temperature rises up to five times faster than an adult’s and heatstroke can set in at 104 degrees. In many cases, a core temperature of 107 degrees is lethal.
How memory lapses destroy lives
26% of hot car deaths occur from children gaining access to vehicles and becoming trapped inside. Another 15% of hot car deaths are a result of children intentionally being left in cars. But the leading cause of car deaths – accounting for over half of all incidents -- is attributed to “Forgotten Baby Syndrome.” It’s a little-known psychological phenomenon whereby the human memory system is thrown out of kilter by a disruption to an individual’s routine. The brain’s “prospective memory” is its intent to remember an unusual task. If it fails, “habit” memory kicks in, effectively putting the person on autopilot. This cerebral short-circuit is the leading contributor to the horrific death toll from hot car incidents.
The beginnings of Child Presence Detection
Initial industry efforts to prevent hot-car incidents were based on simple door sequencing Child Presence Detection (CPD). They were designed to trigger an alert if the driver opened or closed a rear door at the start of their journey and didn’t do so at the end. These low-tech solutions often created false alarms and failed to safeguard children because they were not supported by reliable occupant data. Nor were they able to monitor the whole cabin, footwells or the trunk, or distinguish between adults and children.
4D imaging radar receives FCC approval
Since then, automakers have shifted their focus to one sensor category that can collect high-resolution data throughout the entire vehicle cabin. 4D imaging radar, an affordable and versatile System-on-Chip (Soc) technology, is already used across industries as diverse as senior care, medical diagnostics, retail and smart buildings, delivering real-time environmental intelligence and robust performance while maintaining privacy.
Safety on a global scale
The company's highly affordable platform supports next-generation CPD for all passenger vehicles, from luxury cars to economy models. It ensures complete in-cabin coverage and classification of children and adults, as well as their posture and position. Thanks to its ultra-wide field of view, just one RFIC covers up to three complete seating rows and all footwells, as well as the open trunk. It operates in all lighting conditions and regardless of line-of-sight, enabling it to detect an infant under a blanket in a child seat or a toddler crouching on the floor.
Since it’s based on high-resolution direct sensing, Vayyar’s globally approved warning system meets Euro NCAP’s 2023 CPD standards, one of the few solutions on the market that enables a vehicle to earn the full 4 safety points for this requirement. It also supports enhanced Seat Belt Reminders (SBR) as part of an application-ready feature combo, the foundation of a mold-breaking multifunctional offering.
