  • Publication number: 20200257299
    Abstract: An autonomous vehicle that automatically responds to an emergency service vehicle. Perception data is captured or received by the autonomous vehicle (AV) cameras, sensors, and microphones. The perception data is used to detect lanes in a road, generate a list of objects, classify one or more of the objects, and determine a state for the classified objects. In response to detecting an emergency service vehicle such as a law enforcement vehicle, a responsive action may be planned by the AV. The responsive action may include sending an acknowledgement signal, notifying passengers of the AV, generating a planned trajectory based on the emergency service vehicle location, an emergency service vehicle detected intention, and other information. A safety check may be performed, and commands may be generated by a control module to navigate the AV along the planned trajectory. The commands may then be executed by a DBW module.

  • Publication number: 20200241066
    Abstract: Disclosed is an intelligent on-line diagnosis method for winding deformation of power transformer. When a transformer is subjected to short-circuit shock or transportation collision, transformer windings may undergo local twisting, swelling or the like under the action of an electric power or mechanical force, which is called winding deformation and will cause a huge hidden danger to the safe operation of the power network. Commonly used diagnosis methods for winding deformation are all off-line diagnosis methods, which have the disadvantages that transformers need to be shut down and highly skilled operators are required. The present invention provide an intelligent on-line diagnosis method for winding deformation on the basis of combination of information entropy and support vector machine.

  • Publication number: 20200212684
    Abstract: An automatically generated and customized fast charging process results in reduced degradation in the battery cell. An algorithm for a particular battery cell profile is automatically generated and customized to minimize degradation due to fast charging for that particular batch. To generate the custom algorithm, battery cell information is retrieved for a profile of a battery, wherein each battery profile may have a particular manufacturer, model, type, electrode batch, and potentially other specific identification information. Each battery cell is charged from a particular SOC level and at a selected C-rate, and then discharged. During discharge, the battery cell is monitored for detection of lithium plating or other undesirable effects. A lookup table is automatically generated from the battery cell information, and can be provided to devices and/or battery management systems. The BMS then uses the lookup table to apply a charging process that is customized to the on-board battery.

  • Publication number: 20200207353
    Abstract: An autonomous vehicle automatically implements an intention aware lane change with a safety guaranteed lane biased strategy. To make a lane change, the autonomous vehicle first navigates within the current lane to near the edge of the current lane, to a position offset by a bias. By navigating to the edge of the lane, the autonomous vehicle provides a physical and virtual notification, in addition to a turn signal, that it is the intention of the vehicle to change into the lane adjacent to the edge of the lane in which the vehicle has navigated to. After performing a safety check and waiting for a minimum period of time during which vehicles in the adjacent lane can be assumed to have been warned or been put on notice of the lane change, the autonomous vehicle navigates into the adjacent lane.

  • Publication number: 20200210541
    Abstract: A multiple particle reduced order model accurately predicts lithium plating potential in real time during the life of a lithium battery cell. In the current multi-particle reduced order modeling system, the current density and the potential distributions are solved iteratively. Once the current distribution is solved, lithium concentration distribution is solved without involving any iterative process. By solving the lithium concentration distribution as a separate step after the iteratively determined current density and potential distributions, the computation time required by the model to generate an output is dramatically reduced by avoiding solving multiple partial derivative equations iteratively. Based on the potential distribution information provided by the output of the model, lithium plating potential can be determined and actions can be taken, such as modified charging techniques and rates, to minimize future lithium plating.

  • Publication number: 20200209874
    Abstract: A combined virtual and real environment for autonomous vehicle planning and control testing. An autonomous vehicle is operated in a real environment where a planning module and control module operate to plan and execute vehicle navigation. Simulated environment elements, including simulated image and video detected objects, simulated radar detected objects, simulated lane lines, and other simulated elements detectable by radar, lidar, camera, and any other vehicle perception systems, are received along with real-world detected elements. The simulated and real-world elements are combined and processed to by the autonomous vehicle data processing system. Once processed, the autonomous vehicle plans and executes navigation based on mixed real-world and simulated data in the same way. By adding simulated data to real data, the autonomous vehicle systems may be tested in hypothetical situations in a real-world environment and conditions.

  • Publication number: 20200212429
    Abstract: External forces are applied to a slurry mixture to achieve a more organized slurry structure in the manufacturing of an electrode. A slurry is generated with paramagnetic materials that exhibit magnetic properties when a magnetic field is applied to the slurry. The slurry with the paramagnetic materials is applied to a current conductor, and then a magnetic field is applied to the slurry, for example during an electrode drying process. By applying a magnetic field, the paramagnetic material orientation can be aligned into a more organized structure. In some instances, the alignment creates a porous structure or gap between pillars that form within the dried slurry material. The dried, porous slurry structure allows for electrolyte wetting and ionic accessibility that is greatly improved over electrodes manufactured using typical techniques.
