A driveline assembly for a vehicle including at least one primary shaft rotatable about an axis. At least one reducer assembly is coupled with the at least one primary shaft. The reducer assembly includes a sun gear rotatable with the primary shaft. A plurality of planet gears are rotatable about the sun gear. A ring is positioned about the planet gears. A planet carrier is rotatably connected to a center of each of the planet gears. An output shaft is fixed to the planet carrier. A sliding clutch fixes the ring to a ground in a high torque position to provide a gear reduction, and fixes the ring to the planet carrier in a low torque position to provide a 1:1 gear ratio. A method for operating such a driveline assembly is also provided.

This invention discloses a method and system for detecting pavement structure damage based on radar full-profile map features, comprising: Step 1, acquiring high-density three-dimensional electromagnetic wave data and preprocessing it; Step 2, converting the preprocessed data into a 3D point cloud profile and segmenting it into B-Scan and C-Scan maps, and labeling the structural damage types; Step 3, constructing a dual-input YOLO target detection model including an input terminal, a feature extraction module, a feature fusion module, a multi-scale discrimination module, and a regressor. The input terminal receives the B-Scan and C-Scan maps and transmits them to the feature extraction module to obtain the structural damage feature information corresponding to the B-Scan and C-Scan maps. The feature fusion module stitches the data together to generate fused feature information, which is then transmitted to the multi-scale discrimination module for multi-scale feature fusion and enhancement processing, and finally outputs the prediction result box through the regressor; Step 4, calculating the actual location and size information of the structural damage and a pavement structure damage detail table through a coordinate transformation algorithm.
