Global regulatory mandates for automatic emergency braking (AEB) in passenger vehicles are accelerating the development of advanced sensor fusion architectures. Raytron, a specialist in infrared thermal imaging technology, has partnered with Geely-owned Zeekr to deploy the world’s first thermal-enabled AEB system in the Zeekr 9X flagship SUV. The integration of Raytron’s Horus 640D thermal camera into Zeekr’s G-Pilot H9 platform marks a functional evolution from passive thermal perception to active intervention capability in Level 2+ driver assistance systems.
Highlights
- First Commercial Deployment: Zeekr 9X integrates Raytron’s thermal camera as a core sensor for AEB decision-making, not just auxiliary perception
- Enhanced Detection Range: Thermal imaging extends nighttime object detection to 300 meters, double the effective range of standard low-beam headlights
- All-Weather Reliability: Unlike LiDAR and visible-light cameras, thermal sensors maintain performance in fog, dust, and glare conditions
- Living Object Accuracy: Heat signature detection enables precise identification of pedestrians, cyclists, and animals in low-visibility scenarios
Thermal AEB vs Traditional AEB: Technical Differentiation
Conventional AEB architectures rely on visible-spectrum cameras and millimeter-wave radar to measure time-to-collision and execute emergency braking. Thermal AEB adds an uncooled infrared detector that addresses critical sensor limitations across four operational domains.
Nighttime and Low-Light Conditions
Standard automotive headlights provide 100–150 meters of forward illumination. Raytron’s thermal camera extends detection capability to 300 meters in complete darkness, increasing reaction time on unlit highways and rural roads where animal strikes and pedestrian accidents are statistically elevated.
High-Glare Environments
Visible-light cameras and human vision experience temporary blindness from oncoming headlight glare. Thermal imaging operates in the long-wave infrared spectrum (8–14 μm), rendering it immune to visible light saturation and maintaining uninterrupted object detection during night driving.
Degraded Weather Performance
LiDAR systems experience significant signal attenuation in fog and particulate-dense environments due to optical scattering. Thermal imaging’s longer wavelength penetrates atmospheric obscurants more effectively, preserving image quality when traditional sensors fail to meet minimum detection thresholds.
Biological Target Recognition
Infrared sensors detect thermal radiation emitted by living organisms, enabling differentiation between animate and inanimate objects. This capability is critical for identifying dark-clothed pedestrians, unlit cyclists, and wildlife (deer, wild boars) that pose collision risks in rural and semi-urban environments.
Horus 640D Technical Architecture
The Horus 640D module deployed in the Zeekr 9X integrates three proprietary components: Raytron’s uncooled vanadium oxide microbolometer array, the Falcon-series infrared image processor, and thermal-optimized enhancement algorithms. The 640×512 resolution detector operates without cryogenic cooling, reducing system complexity and power consumption.
Key Specifications:
- Form Factor: 32.5×60.5×43mm compact profile enables grille-mounted installation
- Detection Range: 300+ meters for human-sized targets in zero-lux conditions
- Operating Temperature: -40°C to +85°C ambient range for global deployment
- Power Consumption: Optimized for continuous operation without thermal management overhead
The module’s compact dimensions address a critical OEM constraint: front-grille integration without aerodynamic or aesthetic compromise. This packaging advantage has enabled Raytron’s deployment across 20+ vehicle models with 15 automotive manufacturers, spanning passenger cars, commercial trucks, and autonomous shuttle platforms.
Raytron’s automotive-grade thermal imaging solutions support both Level 2+ ADAS and higher-autonomy architectures requiring redundant perception modalities. Technical documentation and integration specifications are available at https://en.raytrontek.com.
