Abstract: A step assembly for a tailgate of a vehicle, which includes a retractable rail secured to a housing located within the tailgate. The retractable rail is configured to extend from the housing and the tailgate when in a deployed state, and be entirely received within the housing and the tailgate when in a non-deployed state. A sliding stop device is positioned within the housing and connected to an end of the retractable rail. The stop device includes a tubular member having an aperture formed therein, and a movable arm located in the tubular member that is biased to extend outward from the aperture such that as the retractable rail is moved to the deployed state, the aperture of the sliding stop device is aligned with the opening of the housing, and the movable arm is engaged with the opening.
Abstract: Park control systems and methods operate such that, in response to a request to engage or disengage a park pawl of a vehicle park pawl system, a controller commands a hydraulic brake system to maintain a hydraulic brake pressure therein generated in response to depression of a brake pedal by a driver of the vehicle, when vehicle movement is detected after maintaining the hydraulic brake pressure, commands a vacuum-independent electric brake booster to generate and provide additional hydraulic brake pressure to the hydraulic brake system, commands the park pawl system to engage or disengage the park pawl to/from a transmission output shaft, and after the park pawl is engaged or disengaged to/from the transmission output shaft, commands the hydraulic brake system to release its hydraulic pressure at a defined rate.
Abstract: Powertrain propulsive torque monitoring and remedial action techniques for a cruise control mode of an electrified vehicle comprise obtaining a set of inputs indicative of a driver torque request and a state/grade of a road along which the vehicle is traveling, operating in a cruise control mode including determining a total torque request for an electrified powertrain, determining and commanding a distribution of the total torque request to the electrified powertrain, and determining the road state/grade based on at least some of the set of inputs, and monitoring the operating in the cruise control mode including determining an actual torque being generated by the electrified powertrain, determining upper and lower acceptable torque limits for the cruise control mode based on the road state/grade, and taking remedial action regarding the cruise control mode when the actual torque is outside of the upper and lower acceptable torque limits.

Abstract: A laser beam is scanned along spaced apart side-by-side laser tracks to form corresponding spaced apart side-by-side hardened metal tracks across a binder surface of the forming die. Each hardened metal track is oriented to extend longitudinally in a direction that is normal to the metal flow direction across the binder surface during a sheet metal forming operation. The scanning forms the corresponding hardened metal tracks across the binder surface without needing to perform a post-hardening machining operation on the sheet metal forming die to remove distortion caused by the laser hardening process.

Abstract: Systems and methods of detecting and tracking a pole-shaped object proximate to a vehicle comprise down-sampling three-dimensional (3D) light detection and ranging (LIDAR) point cloud data for each of a plurality of frames according to a user-configurable voxel size, filtering the down-sampled 3D LIDAR point cloud data to remove data points corresponding to ground surface reflections, dividing the 3D LIDAR point cloud data into a plurality of clusters that are parallel to the vehicle's moving direction, projecting the plurality of clusters to a plane that is parallel to sides of the vehicle to generate an image, detecting a pole-shaped object in the image, and tracking the pole-shaped object by deep sorting across multiple frames of the plurality of frames.
