Xiaomi SU7 Ultra Reveals ADAS Sensor Suite: Features LiDAR and 4D Millimeter-Wave Radar

On April 9, Xiaomi Auto unveiled the advanced driver-assistance sensor hardware configuration for the top-trim variant of its SU7 series. The system comprises one LiDAR unit, one 4D millimeter-wave radar, eleven cameras, and twelve ultrasonic sensors, all working together to support road data collection and decision-making under Xiaomi’s XLA architecture. The LiDAR is mounted on the roof and provides precise measurements of forward spatial geometry, capable of detecting obstacles up to 200 meters away even in nighttime or low-light conditions. The 4D millimeter-wave radar is integrated into the center of the front bumper and can identify obstacle height, enhancing dynamic perception accuracy in scenarios such as high-speed vehicle following. The eleven high-definition cameras are divided into surround-view and ring-view categories, handling long-range, full-angle road monitoring and close-range blind-spot imaging, respectively. The twelve ultrasonic sensors assist with near-field obstacle detection during parking and low-speed maneuvering. Together, these sensors enable comprehensive environmental awareness around the vehicle, significantly improving the safety and reliability of the advanced driver-assistance system.
