Benchmark-Grade CPD (Child Presence Detection) Surrogates for Next-Generation In-Cabin Safety
Created on 07.24
Child Presence Detection (CPD) is becoming a mandatory safety feature in intelligent vehicles worldwide. As regulatory frameworks (Euro NCAP, ISO, C-NCAP, i-VISTA) move rapidly toward standardization, the demand for accurate, repeatable, and efficient CPD system validation is accelerating.
To meet this critical need, we present an industry-leading CPD test target solution, purpose-built to overcome the key limitations of traditional testing and support multi-modal sensor development across radar, UWB, Wi-Fi, and vision systems.
🔧 Key Performance Highlights
✅ Realistic Vital Sign Simulation
- Simulates child-like breathing and heartbeat with high temporal accuracy and micro-Doppler fidelity.
- Supports programmable patterns such as:
- Rapid breathing (awake/emotional state)
- Slow breathing (deep sleep)
- Apnea and abnormal sequences (false-alarm testing)
- Multi-pattern variability to enhance algorithm robustness

✅ Radar Cross Section (RCS) Matching
- Precisely engineered RCS profiles based on real child scattering data
- Accurate reflectivity across 360° and multiple frequency bands

✅ 14 DOF Behavioral Simulation
- High-torque, modular actuators enable 14 degrees of freedom
- Programmable to mimic natural body movements like limb motion, posture shifts, and spontaneous reactions
- Enables dynamic testing under realistic in-cabin conditions
✅ Full Multi-Sensor Compatibility
- Natively supports:
- 60GHz / 140GHz mmWave radar
- 4D imaging radar
- UWB (Ultra-Wideband)
- 5.8GHz Wi-Fi sensing
- Camera-based vision and AI fusion algorithms
- Seamless integration into test benches or full vehicle validation workflows
✅ Age-Specific Target Library
- Covers high-risk age groups: 0, 1, 3, and 6 years old
- Match child anthropometry
- Provides full coverage for CPD algorithm tuning across all use cases
