Abstract: A method for storing shard data and data formats for storing shard data are proposed. Shard data entries are generated and stored, wherein each shard data entry comprises a definition of one or more semantic objects covered by the shard data entry. Shard metadata is generated and stored, wherein the metadata comprises references to the shard data entries and, for each of the shard data entries, data representative of a bounding box indicative of an area in a geographical area that is covered by the shard data entry.
Abstract: Presented are torque converters (TC) with hydraulic systems for converter feed and clutch control, methods for making/operating such TC assemblies, and vehicles equipped with such TC assemblies. A TC assembly includes a housing that drivingly connects to an electric motor, and an output member that drivingly connects to a multi-gear transmission. Rotatable within the TC housing are a turbine attached to the TC output member and an impeller juxtaposed with the turbine. A lockup clutch disposed inside the TC housing, between the turbine and housing, is operable to lock the housing to the output member. A disconnect clutch disposed inside the housing, between the impeller and housing, is operable to lock the housing to the impeller. A pump is attached to the TC housing and drivingly connected to the motor for feeding fluid into the housing to increase pressure within the TC chamber and activate the lockup and disconnect clutches.

Abstract: The present disclosure provides a method including determining an operational mode of a vehicle based on data accumulated from at least one vehicle information system associated with the vehicle; selecting one of a plurality of power consumption profiles for the vehicle based on the determined operational mode; and applying the selected one of the power consumption profiles to the vehicle.
Abstract: A method includes determining that an object has fallen to a surface of interest in an interior cabin of a vehicle during a transportation service provided using the vehicle; tracking a location of the object on the surface of interest using at least one interior sensor; updating tracking information for the object, the tracking information including the tracked location of the object and a time at which the location was tracked; inferring a continued existence of the object after the object has moved out of a view of the at least one interior sensor and tagging the object as obscured from view in the tracking information for the object; identifying a user associated with the transportation service; and alerting the identified user to retrieve the object.

Abstract: Systems, methods, and devices are disclosed for synchronizing map updates for a navigating autonomous vehicle. A management service on a managing node can receive an update to a portion of a first map, where a limited visibility map, which is a subset of the first map, can be determined based on a geographical area around an autonomous vehicle navigating a route. The limited visibility map can be synchronized among all the nodes while the autonomous vehicle is using the limited visibility map by the management service delivering, to a plurality of downstream nodes, the update to the limited visibility map when the update does not modify a portion of the limited visibility map, and by bypassing, to the plurality of downstream nodes, the update to the limited visibility map when the update modifies a portion of the limited visibility map.

Abstract: A system for quantitively determining quality for pavement markings disposed along pavement on a roadway includes one or more controllers in wireless communication with a plurality of vehicles. The one or more controllers receive image data represents the pavement markings disposed along the pavement collected by the plurality of vehicles. The one or more controllers execute instructions to determine at least one of a color distance measurement between a mean color space value of the pavement markings and an ideal marking color space value and a marking intensity contrast ratio between the pavement markings and the pavement.

Abstract: Presented are lithium-metal electrodes for electrochemical devices, systems and methods for manufacturing lithium-metal foils, and vehicle battery packs containing battery cells with lithium-metal anodes. A method of melt spinning lithium-metal foils includes melting lithium (Li) metal stock in an actively heated vessel to form molten Li metal. Using pressurized gas, the molten Li metal is ejected through a slotted nozzle at the base of the vessel. The ejected molten Li metal is directly impinged onto an actively cooled and spinning quench wheel or a carrier sheet that is fed across a support roller underneath the vessel. The molten Li metal is cooled and solidified on the spinning wheel/carrier sheet to form a Li-metal foil. The carrier sheet may be a polymeric carrier film or a copper current collector foil. An optional protective film may be applied onto an exposed surface of the Li-metal foil opposite the carrier sheet.

Abstract: A system for on-vehicle camera alignment monitoring includes an on-vehicle camera in communication with a controller. The controller monitors vehicle operating parameters and camera signal parameters, and captures an image file from the on-vehicle camera. A first level analysis of the image file, the vehicle operating parameters, and the camera signal parameters is executed to detect dynamic conditions and image feature parameters that affect camera alignment. An error with one of the dynamic conditions or the image feature parameters that affects the camera alignment is detected. A second level analysis of the camera signal parameters is executed to identify a root cause indicating one of the dynamic conditions or the image feature parameters that affects the camera alignment based upon the error. A camera alignment-related fault is detected based upon the root cause, and vehicle operation is controlled based upon the camera alignment-related fault.
