With the rapid development of intelligent cabins, active safety and in-cabin vital sign sensing technologies, Child Presence Detection, CPD, is becoming a key focus in global vehicle safety assessment and intelligent cabin innovation. Reliable CPD validation under realistic, complex and repeatable conditions has become an important challenge for OEMs, sensor suppliers, testing organizations and standardization bodies.

To address this industry need, PRIAUTO has developed a high-fidelity CPD child target that provides a standardized, repeatable and quantifiable test object for the development, calibration, evaluation and validation of in-cabin child presence detection systems. Designed for realistic cabin environments and multiple sensing technologies, the PRIAUTO CPD target can systematically reproduce various child presence conditions and key detectable characteristics, providing a professional, reliable and future-oriented solution for intelligent cabin safety validation.

The PRIAUTO CPD target is more than a child-shaped test surrogate. It is an integrated test platform for intelligent cabin safety evaluation. By combining child-like body dimensions, physiological micro-motion, thermal characteristics, visual features, multi-posture adaptability and multi-sensor response characteristics, it helps the industry move beyond the basic question of whether a child can be detected, toward a higher-level evaluation of whether the system can detect a child reliably, consistently and repeatably in complex real-world scenarios.

Real vehicle cabin environments are far more complex than simplified laboratory conditions. Children may appear in different ages, postures, seating positions, occlusion conditions and cabin areas. Conventional static dummies or low-fidelity test objects are not sufficient to fully validate the detection capability, interference resistance and robustness of CPD systems in complex cabin environments.

The PRIAUTO CPD target is designed for realistic in-cabin use scenarios and can support a wide range of typical and challenging test conditions, including:

With its adaptability to multiple postures, positions and occlusion conditions, the PRIAUTO CPD target helps users evaluate CPD system performance more comprehensively in real vehicle environments. From standard seated postures to challenging edge cases such as occlusion, low reflection, abnormal posture and marginal cabin positions, the target provides a stable and consistent test foundation for system development and evaluation.

CPD systems are developing along multiple technical routes, including millimeter-wave radar, UWB, Wi-Fi, vision, thermal imaging and multi-sensor fusion. Different sensors rely on different detectable characteristics of a child target, which requires the test object to provide more comprehensive sensor response features.

The PRIAUTO CPD target is developed to support a wide range of in-cabin sensing technologies, including:

In addition to geometric shape and body dimensions, the PRIAUTO CPD target can reproduce multiple key characteristics closely related to child presence detection, including respiratory motion, heartbeat-related micro-motion, human body thermal radiation, eye blinking, child-like visual appearance and posture variation.

These capabilities enable the target to go beyond simple shape representation and more closely approximate the sensor response of a real child across radar, vision, thermal sensing and wireless sensing domains. For CPD system development and algorithm validation, this means more realistic test inputs, more reliable validation results and stronger benchmarking capability across different technical approaches.

Children of different ages vary significantly in body dimensions, breathing characteristics, posture behavior and sensor response. To meet the needs of different test protocols, product development programs and research validation tasks, the PRIAUTO CPD target series covers typical child age groups, including 0-year-old, 1-year-old, 3-year-old and 6-year-old children.

Targets for different age groups can be configured according to specific test requirements, supporting combinations of respiration frequency, respiration amplitude, posture movement, body temperature simulation, eye movement and heartbeat-related micro-motion. By covering different ages, postures and sensing characteristics, the PRIAUTO CPD target series helps users build a more complete test matrix for child presence detection validation.

The series can be used not only for basic detection capability verification, but also for advanced sensor algorithm development, multi-sensor fusion testing, vehicle-level cabin safety assessment and forward-looking test protocol research. It provides full-process support for intelligent cabin safety systems from R&D to validation.

As global attention to in-vehicle child safety continues to increase, CPD validation is moving from simple functional testing toward standardized, protocol-based and quantitative evaluation. Future CPD systems must be able to detect children not only under ideal conditions, but also under complex cabin layouts, different child postures, occlusion conditions, environmental disturbances and multi-sensor configurations.

The PRIAUTO CPD target can be widely used for:

Through standardized test targets and controllable test conditions, the PRIAUTO CPD target helps R&D and testing organizations improve test consistency, reduce validation uncertainty, enhance comparability among different technical approaches and accelerate the transition of CPD technology from concept validation to engineering application and assessment implementation.

The PRIAUTO CPD target integrates realistic child body characteristics, controllable physiological micro-motion, multi-posture adaptability, multi-age coverage and multi-sensor compatible design. It provides a high-fidelity, system-level and scalable test platform for intelligent cabin safety validation.

The product not only supports the development and validation of current in-cabin child presence detection systems, but also provides a foundation for future intelligent cabin technologies, including occupant sensing, vital sign monitoring, cabin safety warning, abnormal state recognition and multi-modal sensing fusion. As intelligent vehicles evolve from transportation tools into intelligent mobile spaces, in-cabin life safety sensing will become an important dimension of intelligent cabin competitiveness, and high-confidence test targets will become indispensable infrastructure for system validation.

For safer intelligent vehicles and intelligent cabins, PRIAUTO will continue to advance the development of high-fidelity test targets, standardized test methods and systematic validation tools. The company is committed to providing more professional and forward-looking testing support for active safety, intelligent driving and in-cabin monitoring systems, contributing to a higher level of safety development in the global intelligent vehicle industry.
