Frequently Asked Questions
What is the HESAI ETX LiDAR used for?
The HESAI ETX is an automotive grade 120° ultra long range LiDAR designed for L3 autonomous driving, advanced ADAS, robotaxi, and high speed vehicle perception. It is built for front facing long distance detection where vehicles need more time to identify road hazards and react safely.
Why is it important for L3 autonomous driving?
It provides ultra long range perception, high resolution point clouds, and a slim low profile form factor that supports roof or behind windshield integration — engineered for L3 and L4 autonomous driving applications.
What is the detection range of the HESAI ETX?
Listed ranging capability is up to 400 m at 10 percent reflectivity — suitable for long distance highway perception, early object detection, and an expanded safety margin in higher level autonomous driving systems.
What makes it different from AT128?
It reaches up to 400 m at 10 percent reflectivity, approximately twice the ranging capability of the AT128, while its 0.05° x 0.05° angular resolution provides significantly higher detail for object detection.
Why does small object detection matter?
L3 and L4 vehicles must identify distant road hazards early, not only large vehicles. The sensor can detect small objects, such as wooden blocks measuring 15 x 25 cm, at distances of up to 150 m, supporting safer high speed driving decisions.
Can it be installed behind the windshield?
Yes. It can be mounted behind the cabin windshield and features a reduced window height compared with earlier models, supporting more efficient in cabin LiDAR integration without large external sensor housings.
What is Photon Vector Technology?
A proprietary technology that extends ranging capability while maintaining Class 1 eye safety and reducing size and power consumption — improving ranging performance while keeping the sensor compact and efficient.
How powerful is the point cloud output?
Up to 5,600,000 points per second in single return mode — dense 3D perception for long range ADAS and autonomous driving scenarios where distant vehicles, pedestrians, and road objects need to be detected clearly.
Is it suitable for automotive safety and compliance requirements?
Yes. Listed items include Class 1 Eye Safety, ISO 26262 ASIL B Functional Safety Product Certification, ISO 21434 Cybersecurity Product Certification, and an ISO 21448 compliant development process.
When should a team choose the HESAI ETX?
Choose the ETX when you need an automotive grade ultra long range LiDAR for L3 autonomous driving, L4 fleet development, robotaxi perception, highway ADAS, or behind windshield front sensing — most relevant when 400 m class detection, small object recognition, high point density, and compact low profile vehicle integration are key requirements.
