XPENG: when a lidar checks its own alignment
A sensor may collect millions of points yet still be misaligned. This patent addresses the orientation of the sensor relative to the vehicle.
Canvas of Knowledge · 14 November 2026 · Illustrated explainerThe problem
Installation changes or service work can introduce angular offsets. Those offsets distort the relationship between the lidar’s point cloud and the vehicle’s coordinate system.
The proposal
The disclosed system uses reference objects in lidar data to estimate tilt components and compensate offsets. The granted claims include particular road-slope measurements and consistency conditions.
The evidence
US12523751B2 was granted and published on 13 January 2026 to Guangzhou Xiaopeng Autopilot Technology Co., Ltd. This is a calibration invention, not proof of unsupervised-driving capability.
THE IDEA TO KEEPA patent about a sensor subsystem does not certify the safety of an entire driving system.
