The stringent legislative mandates, which considers consumer safety as the top priority forces OEMs to comply with these requirements. For instance, the U.S. Infrastructure Investment and Jobs Act mandates that all new passenger vehicles sold after 2025 must include a CPD solution, making child safety systems non-negotiable.
The potential benefits these mandates can bring to adjacent and associated markets and supply chains make them pivotal. For instance, Euro NCAP’s 2023 inclusion of child presence detection testing in its safety ratings has led large European OEMs such as Renault and Stellantis to reconsider radar-based cabin monitoring solutions as standard features. This regulatory domino effect is encouraging tier-1 suppliers to develop compact, low-power mmWave radar sensors, such as Texas Instruments’ AWRL1432, which enables child detection with sub-5cm accuracy at under 500mW power consumption. Policy enforcement is reshaping product development, R&D, and in-cabin safety system design.
The adoption of automotive CPDS has struggled to gain sufficient traction, as OEMs grapple with the cost-performance trade-off inherent in sensor integration, particularly in price-sensitive vehicle segments. While advanced radar-based CPD modules offer superior accuracy in detecting micro-movements such as the breathing patterns of infants in the car, their high bill-of-materials (BOM) cost, complex calibration requirements, and the need for dedicated electronic control units (ECUs) deter their incorporation into compact and entry-level vehicles. For instance, while premium OEMs such as Mercedes-Benz use in-cabin radar for CPDS in high-end models, budget automakers often rely on cheaper pressure or ultrasonic systems, which are prone to false positives and limited in range.
This technology gap is especially critical in emerging markets, where even a slight increase in CPDS production costs can significantly affect consumer adoption and OEM pricing strategies. Compliance with evolving regulatory benchmarks further complicates the engineering process that low-cost CPDS solutions struggle to meet. The market must confront a dual challenge of achieving regulatory-grade precision without inflating system costs, especially in regions where child presence systems are not yet legally mandated but are increasingly expected due to rising consumer awareness of safety.
Auto OEMs are tapping into opportunities that lie at the convergence of CPDS with next-generation cabin intelligence platforms. With a large portion of automakers moving toward software-defined vehicles, CPDS are graduating from basic safety add-ons into multi-modal, sensor-fused occupant monitoring systems (OMS) that also enable wider human-machine interaction (HMI). Tier-1 suppliers such as Bosch and Valeo are already prototyping radar-camera hybrid modules that detect unattended children and are also capable of detecting of driver drowsiness, gesture controls, and health tracking.
The convergence of CPDS and cabin premiumization is opening up new monetization avenues, particularly in the premium and electric vehicle segments, where over-the-air (OTA) upgrades and subscription-based services have gained firm ground in the auto industry. For example, Tesla’s internal heat detection logic could be enhanced with CPD-linked alerts as part of a paid safety suite. What is evident is that vehicles today have become data-rich environments. CPDS that support multi-function capabilities can command higher average selling prices (ASPs), drive platform-level integration contracts, and generate downstream revenue through AI-driven safety analytics.
Radar sensors are expected to be the largest sub-segment in the sensor segment in 2025, holding a market share close to 48%. It is also estimated to register the highest CAGR through 2032. Radar-based CPDS modules exhibit superior accuracy in detecting micro-movements, such as infant breathing or minor shifts in seating positions, which pressure or ultrasonic sensors often fail to detect. Automakers across North America and Europe, responding to the U.S. CPD legislation and Euro NCAP’s evolving safety protocols, are integrating 60 GHz and mmWave radar sensors as OEM-installed safety technology, bypassing aftermarket alternatives. Radar sensors have become essential across both mass-market and luxury vehicle lines.
The other reason for the high-velocity growth of this sub-segment is the innovation in sensor fusion, AI-enhanced signal processing, and edge computing, which empower radar systems to deliver both safety compliance and enhanced occupant monitoring. Recent industry deployments, such as the integration of ultra-wideband radar capable of detecting chest micro-motion by Continental, strongly illustrate how radar-based modules are evolving into multiplatform interior sensing hubs, ensuring compliance while also premiumizing in-cabin sensing architecture.
Sedans are forecast to hold the largest revenue share of approximately 43% in 2025. The primary reason is that they are the backbone of global automotive fleets in both mature and emerging markets. These vehicles are typically offered with mid-to-high trim safety packages, and OEMs prefer to integrate CPDS into sedans to meet legal requirements and boost customer confidence. The consistent volume of sedan sales in North America, Europe, and Asia, most notably among families, comprehensively explains this leadership. For example, the top-selling models for Toyota throughout 2024 were the Yaris and Corolla ranges, the brand’s most popular sedans.
SUVs are expected to display the highest growth rate during the forecast period 2025-2032. The strong performance of the SUV sub-segment is due to the shift among car buyers toward larger, family-sized vehicles with premium upgrades. Consumers are increasingly favoring SUVs for style, platform versatility, enhanced interior space, and robust in-cabin safety infrastructure. OEMs are leveraging this trend by standardizing CPDS with advanced sensor suites in SUV variants, especially electric and luxury models. This has created opportunities for sensor suppliers and tier-1 integrators to develop recurring revenue streams by bundling advanced safety features.

North America is forecast to lead with 37% of the market share in 2025. In the U.S. and Canada, robust policies specifically designed to enhance vehicular safety, such as the U.S. Hot Cars Act and rear-seat reminder mandates by the Alliance for Automotive Innovation (AAI), require OEMs to include CPDS across their fleet by 2025. Consumer groups and insurers are also actively undertaking awareness campaigns, highlighting the possibility of children succumbing to heatstroke in as little as 10 minutes. These regulatory and societal forces have erected high-entry barriers for OEMs, which have accelerated the integration of CPDS technologies, especially radar-based or multi-sensor suites, in sedans, SUVs, and luxury EVs.
For auto CPDS market players, North America offers immense opportunities for the supply of advanced CPDS hardware (radar and ultrasonic sensors), AI-based processing platforms, and integrated occupant monitoring systems. OEMs can capitalize on early regulatory alignment and a broadening customer base willing to pay premium prices for vehicle safety features.
Asia Pacific is projected to showcase the highest CAGR through 2032, with its phenomenal expansion marked by voluminous vehicle sales in China, India, and South Korea. Improving spending capacity in India and China has fueled consumer expectations for vehicle safety, favoring this market. OEMs such as VinFast have started integrating radar-AI-based child presence systems into EV models such as the VF6.
Regulatory support from governments across the region is also mandating strict CPDS standards for school buses and new vehicle safety features. The fast-changing economic and regulatory landscape drives strong demand across OEM and aftermarket channels, allowing suppliers to quickly scale radar and ultrasonic CPD modules and tap into retrofit markets for older vehicles. The region’s broader growth trajectory has stimulated the development of cost-optimized sensor technologies and retrofit CPDS kits, while also strengthening regional OEM alliances. Companies that combine low-cost radar sensors with edge-AI detection are well-positioned to capture significant market share, particularly in high-volume SUV and electric sedan segments.
The Europe automotive CPDS market is driven by comprehensive EU vehicle safety mandates and increased demand for in-vehicle child safety features. The EU’s General Safety Regulation (GSR) 2019/2144, which came into force in July 2022, mandates the incorporation of a suite of advanced driver assistance systems (ADAS) in new vehicles, including provisions around driver attention warning systems and indirect occupant monitoring systems. Although CPDS does not find an explicit mention in the regulation, the Euro NCAP's 2023-2025 roadmap lays strong emphasis on child presence detection as a scoring criterion, forcing automakers to include it in future models.
These mandates have already led large automakers such as Mercedes-Benz and Volvo to integrate radar-based occupant detection into premium models. As is evident, Europe presents a high profit-making opportunity for CPDS providers offering advanced in-cabin radar, sensor fusion platforms, and AI-powered occupant analytics that align with Euro NCAP test protocols. Tech firms can also tap into these regional trends by developing solutions that are compliance-ready and scalable for Euro 7, laying the groundwork for long-term partnerships with European auto OEMs.
