Summary: YFORE Technology has shown a UWB radar sensing portfolio that runs child presence detection, occupant counting, hands-free tailgate access, intrusion alerts and parking assistance from a single ultra-wideband hardware layer. The portfolio was demonstrated at the Tier 1 supplier’s new Suwanee, Georgia facility, which opened on 26 August 2026.
Key engineering takeaway: The in-cabin element of the UWB radar sensing system uses high-penetration pulse signals to pick up micro-breathing rather than an optical line of sight. YFORE puts the life-detection rate above 99%, with signal leakage through the glass held under 20 cm to suppress false triggers from outside the vehicle, and a response time inside the Euro NCAP 13-second limit. Kick-sensing activation is claimed above 98% with false triggers below 0.5% in rain, washes and animal movement, and the parking function sits behind bumper panels rather than in ultrasonic sensor cutouts.
Why it matters: Reusing one UWB radar sensing layer across cabin monitoring, entry and parking is a bill-of-materials and packaging argument rather than another sensor added to the vehicle. Removing ultrasonic cutouts from the bumper and apertures from the headliner takes out tooling, wiring and assembly steps, and the claimed 2 kWh nightly saving from waking cameras only on proximity is a parasitic-load figure worth checking against real sentry-mode duty cycles. For engineers working to the Euro NCAP child presence detection requirement, the comparison to make is against 60 GHz mmWave and vision-based systems already in production.
Global Tier-1 automotive supplier YFORE Technology showcased its advanced Ultra-Wideband (UWB) radar sensing portfolio and expanded multi-scenario applications at its Suwanee, Georgia facility. Powered by proprietary high-precision algorithms, YFORE enables versatile multi-functionality from vehicle UWB hardware across in-cabin safety, vehicle access, and automated parking.
Unaffected by optical line-of-sight limitations, YFORE’s UWB In-Cabin Monitoring System utilizes high-penetration pulse signals to detect subtle micro-breathing for Child Presence Detection (CPD). With a life-detection rate exceeding 99% and signal leakage through windows kept under 20 cm, the system reliably prevents false triggers while meeting Euro NCAP safety standards (<13s response time). In parallel, the UWB Occupant Detection System determines multi-target spatial coordinates to report exact passenger counts for emergency eCall response. YFORE also showcased its Occupant & Driver Monitoring System (ODMS), which fuses radar with smart vision mirrors to eliminate visual blind spots behind seats.
UWB Radar Sensing Moves Outside The Cabin
The portfolio expands UWB radar capabilities to vehicle exterior scenarios:
- Kick-Sensing Access: Delivers hands-free liftgate access with an activation rate >98% and false triggers <0.5% during rain, washes, or animal movement.
- Intrusion Detection: Monitors side windows and liftgates for instant alerts upon unauthorized physical entry.
- Low-Power Sentry Mode: Uses proximity radar to awaken power-intensive cameras strictly on demand, saving up to 2 kWh nightly.
Parking Detection Behind The Bumper Panel
The UWB Parking Assistance System accurately identifies parallel, perpendicular, and angled parking spaces while detecting low-profile obstacles and filtering ground clutter. Operating invisibly behind bumper panels, it enables a clean, sensor-cutout-free vehicle exterior without relying on conventional ultrasonic sensors.
Frequently Asked Questions
What is UWB radar sensing in a vehicle?
UWB radar sensing uses short ultra-wideband impulses, typically in the 6 GHz to 8.5 GHz band, to measure the distance and movement of objects around and inside a car. Because the same radio hardware already used for digital key ranging can be reused for detection, one UWB layer can serve cabin monitoring, keyless entry and parking rather than requiring a separate sensor set for each function.
How does UWB radar detect a child left in a car?
The system looks for the very small chest and abdomen movements produced by breathing. UWB impulses penetrate soft materials such as blankets, clothing and seat backs, so a sleeping child in a rear-facing seat or under a cover can still be detected where a camera has no line of sight. YFORE states a life-detection rate above 99% for its implementation.
What is the Euro NCAP child presence detection requirement?
Euro NCAP awards points under its safety assessment for systems that detect an unattended child in the vehicle and escalate an alert to the driver and beyond the vehicle. Direct sensing systems, which physically detect the occupant rather than inferring presence from door and seat logic, score higher. YFORE reports a response time under 13 seconds for its UWB system against that assessment.
How does UWB parking assistance differ from ultrasonic parking sensors?
Ultrasonic sensors need holes cut in the bumper and a visible sensor face, which adds tooling, sealing and paint operations. YFORE says its UWB parking system works through the bumper panel itself, so the cutouts disappear. The company also claims the system filters ground clutter and picks up low-profile obstacles that sit near the noise floor for ultrasonics.
What is the difference between UWB radar and 60 GHz mmWave for in-cabin sensing?
Both detect breathing motion without a camera. 60 GHz mmWave offers finer range resolution in a very small module and is the more common choice for dedicated child presence detection. UWB operates at a much lower frequency, penetrates materials more readily and shares hardware with digital key and access functions, which is the integration argument YFORE is making. The trade-off is resolution against reuse.
