Key Features & Performance
-
Ultra-High Resolution: Features 128 channels of genuine e-scanning, providing an “image-like” point cloud. This level of detail allows the perception system to distinguish between small objects (like traffic cones or debris) and pedestrians at significant distances.
-
Superior Ranging: It can detect objects with 10% reflectivity (like dark clothing or tires) at a distance of 210 meters, giving the vehicle more time to react at highway speeds.
-
High Data Throughput: Generates over 1.53 million points per second (single return), ensuring no gaps in the horizontal or vertical field of view.
-
Automotive-Grade Reliability: Designed for mass production, it meets strict AEC-Q standards and has passed over 50 design validation tests, including extreme temperature cycles and high-pressure water resistance (IP6K7 & IP6K9K).

Why It Stands Out
Unlike traditional mechanical LiDARs that use bulky spinning assemblies, the AT128P utilizes a compact hybrid design that is easier to integrate into a vehicle’s roofline or grille. It also features proprietary interference rejection, which prevents the sensor from being “blinded” by the LiDAR signals of other nearby vehicles.
Note: The AT128P is widely used by major automotive OEMs (such as Li Auto and Lotus) because it balances high-end performance with a form factor that doesn’t compromise vehicle aesthetics.
