Product Introduction

The ASEAN NCAP 1-Year-Old Child Presence Detection Surrogate is a high-fidelity in-cabin test device developed for Child Presence Detection system validation and assessment under ASEAN NCAP-related test requirements. Representing the body size, respiration characteristics, posture features, thermal signature, limited motion behavior, and multi-sensor perception properties of a typical 1-year-old child, the surrogate provides a repeatable and controllable platform for evaluating CPD system performance in realistic vehicle cabin scenarios.

This surrogate is designed for typical infant and young-child CPD use cases, including rear-facing child seats, forward-facing child seats, rear-seat occupancy, sleeping postures, partially covered conditions, and low-motion or weak-signal states. It integrates programmable abdominal respiration, controlled 5-DoF motion, and mandatory body temperature simulation, enabling reliable evaluation of radar-, Wi-Fi-, UWB-, vision-, thermal-, and multi-sensor-fusion-based CPD technologies.

The surrogate can generate respiration-related radar micro-Doppler signatures and representative radar cross-section characteristics comparable to those of real young children. With integrated thermal simulation, it also supports thermal camera and infrared sensing validation under different cabin temperature and child-seat conditions.

Key Capabilities

The surrogate is designed to support comprehensive CPD validation for ASEAN NCAP-oriented 1-year-old child occupant scenarios.

It supports 5 GHz Wi-Fi sensing, UWB, 24 GHz radar, 60 GHz millimeter-wave radar, 140 GHz millimeter-wave radar, 4D imaging radar, thermal sensing, vision-based sensing, and multi-sensor fusion systems. Through programmable respiration, body temperature simulation, and controlled body motion, the surrogate enables repeatable simulation of typical child states, including sleeping, resting, shallow breathing, irregular breathing, intermittent movement, partially covered presence, and low-motion conditions.

The product provides:

• Anthropometric representation of a 1-year-old child
• Programmable abdominal respiration simulation
• Mandatory body temperature simulation
• Respiration-related radar micro-Doppler response generation
• Representative radar cross-section characteristics of real young children
• 5-DoF child motion configuration
• Multi-sensor compatibility for radar, Wi-Fi, UWB, vision, thermal, and fusion-based systems
• Support for ASEAN NCAP-related CPD test requirements and customized CPD protocols
• Repeatable validation for rear-facing child seat, forward-facing child seat, rear-seat, partially covered, and low-motion scenarios

The ASEAN NCAP 1-year-old configuration does not include heartbeat simulation or eye-blink control, and these functions are not provided as optional modules for this version.

Physiological and Thermal Simulation

The surrogate provides adjustable respiration parameters and mandatory thermal simulation to reproduce key detectable features of a 1-year-old child inside the vehicle cabin.

• Respiratory rate: 10–50 bpm, adjustable
• Respiratory amplitude: 1–20 mm, adjustable
• Respiratory mode: abdominal breathing
• Breathing pattern: fixed, programmable, random, periodic, or event-triggered
• Body temperature simulation: included as standard configuration
• Heartbeat simulation: not included and not optional
• Eye-blink control: not included and not optional

These functions allow the surrogate to simulate quiet sleep, shallow breathing, irregular breathing, weak breathing, temporary breathing pauses, partially covered presence, and other low-motion child presence conditions. The mandatory body temperature simulation supports evaluation of thermal and infrared sensing systems, as well as multi-sensor fusion algorithms that combine thermal, radar, UWB, Wi-Fi, or vision inputs.

Programmable Motion Simulation

The ASEAN NCAP 1-Year-Old Child Presence Detection Surrogate adopts a 5-DoF motion configuration to reproduce limited but representative motion behavior of a young child during CPD testing.

Motion Configuration: 5 DoF

• Head rotation: 1 DoF
• Left arm forward swing: 1 DoF
• Right arm forward swing: 1 DoF
• Left leg forward swing: 1 DoF
• Right leg forward swing: 1 DoF

The motion system supports predefined, programmable, and random motion sequences, enabling the simulation of slight child movement, intermittent limb motion, posture adjustment, and low-amplitude body activity in realistic in-cabin scenarios.

Advanced Breathing Simulation

9 Intelligent Control Modes

The surrogate incorporates a nine-mode intelligent breathing control system to reproduce dynamic respiratory variation under different 1-year-old child states. Compared with conventional fixed-pattern respiration devices, this system provides more realistic and challenging test conditions for CPD sensors and algorithms.

The breathing control modes include:

1. Fixed breathing rate with increasing amplitude
2. Fixed amplitude with increasing breathing rate
3. Fixed breathing rate with amplitude increasing and then decreasing
4. Fixed amplitude with breathing rate increasing and then decreasing
5. Fixed breathing rate with randomly fluctuating amplitude
6. Fixed amplitude with randomly fluctuating breathing rate
7. Random variation of both breathing rate and amplitude within defined limits
8. Occasional random breaths inserted during normal breathing
9. Occasional breathing pauses inserted during normal breathing, with adjustable pause frequency

These modes support the simulation of regular breathing, shallow breathing, deep sleep, irregular respiration, weak respiration, restlessness, and apnea-like pauses. They are especially valuable for evaluating CPD systems under weak-signal, low-motion, or highly variable respiration conditions.

Standard Thermal Function

For the ASEAN NCAP 1-year-old configuration, body temperature simulation is included as a standard function. The thermal module provides a controllable thermal signature similar to that of a real young child and supports thermal camera and infrared sensor validation under different vehicle cabin conditions.

The thermal function is suitable for:

• Thermal-based CPD system validation
• Infrared sensor performance evaluation
• Partially covered child detection scenarios
• Child-seat thermal detection scenarios
• Multi-sensor fusion testing with radar, Wi-Fi, UWB, vision, and thermal inputs
• Low-motion child presence detection under cabin temperature variation
