4activeOD-3YO
solutions for Child Presence Detection (CPD)

The 4activeOD-3YO is Euro NCAP-certified for child presence detection testing – validated under Euro NCAP Test and Assessment Protocol – Child Presence Detection  v1.3. With 17 degrees of freedom and the ability to simulate simple speech sequences, it is the most biomechanically complex CPD dummy available for three-year-old occupants.
A three-year-old child moves spontaneously and unpredictably – less constrained than an infant, more erratic than an older child. Validating CPD systems against that behavior demands a test tool that replicates it accurately, not a simplified approximation.
The 4activeOD-3YO simulates age-appropriate head, arm, and leg movements across four behavioral states: Deep Sleep, Sleep, Wake Up, and Awake – including spontaneous active motion and simple speech sequences. All movement patterns are selectable and reproducible, independent of external variables. A proprietary skin material matches the radar properties of real human tissue: electromagnetic waves penetrate only a few millimeters depending on frequency, just as with real skin, while all internal mechatronic components remain fully shielded and invisible to sensors. Compatible with radar, camera, infrared, UWB and LiDAR.
Developed within the international Child Presence Detection (CPD) Consortium Project – more than 35 OEMs, Tier-1 suppliers, research institutions, and regulatory bodies – and confirmed as part of the only fully certified CPD dummy family covering all relevant child age groups.
