Abstract: A system and method for determining a frequency response of a power steering system is disclosed including a steering assist motor configured to generate an assist torque about an axis of a steering shaft when activated. The method includes monitoring, by a controller, a torque transducer that measures a steering output torque of the steering shaft experienced during a first frequency sweep and a second frequency sweep. The method also includes determining, by the controller, a transfer function based on the steering output torque monitored during the first frequency sweep and the second frequency sweep, where the transfer function indicates the response by the power steering system.
Abstract: A hydrocarbon injector deflector for a diesel exhaust system includes a base plate having a first end linearly extending to a second end to define a first side and a second side. The base plate is arcuately formed such that the first side extends arcuately to the second side. The first end is disposed upstream of the exhaust system relative to the second end. The hydrocarbon deflector further includes a frame connected to the second end of the base plate and extends therefrom at a first angle. The frame has an opening formed through the frame.

Abstract: A number of variations may include a product that may include a linking member that may have links arranged in rows that have multiple pitch lengths. Each of the rows may have at least one link. Each of the multiple pitch lengths may be a discrete length that may be different from others of the multiple pitch lengths. The rows may be arranged along the linking member in a repeating sequence of the multiple pitch lengths.
Abstract: A user interface device is described herein that executes a chat application to transmit and/or receive text on a character-by-character basis as a message is being typed. The user interface device establishes a communication link to a remote computing device, wherein one or more outputs each defining a character of the text are transmitted and/or received by the user interface device through the communication link. The characters of the text are displayed in real-time as the one or more outputs are generated. The communication link between the user interface device and the remote computing device can be further established through an autonomous vehicle.

Abstract: Autonomous vehicles and techniques that can be utilized to compress point cloud data and operate on compressed point cloud data are provided. An autonomous vehicle can include a data compression system can configure point cloud data according to a collection of three-dimensional (3D) tiles representative of the region. Each 3D tile can include a portion of the cloud point data, where each point vector in the portion of the cloud point data can be configured relative to a position vector of the 3D tile defined in a coordinate system of the collection of 3D tiles. The data compression system can utilize a fixed-point Q-format representation based on a defined number of bits to compress at least a portion of the point cloud data. The autonomous vehicle also can include a control system that can operate mathematically on compressed point cloud data, without reliance on prior decompression.
Abstract: Processor-implemented methods and systems that perform target verification on a spectral response map to remove false alarm detections at the beamforming stage for sensing radars (i.e., prior to performing peak response identification) using a convolutional neural network (CNN) are provided. The processor-implemented methods include: generating a spectral response map from the radar data; and, executing the CNN to determine whether the response map represents a valid target detection and to classify the response map as a false alarm when the response map does not represent a valid target detection. Subsequent to the execution of the CNN, only response maps with valid targets are processed to generated therefrom a direction of arrival (DOA) command.
Abstract: Systems and methods are provided for controlling a lateral position of a vehicle through an intersection. The method includes receiving, by a processor, intersection data transmitted by an infrastructure associated with the intersection, the intersection data including at least a position of a plurality of lanes associated with the intersection. The method includes receiving, by the processor, a position of the vehicle, and determining, by the processor, a current lane of travel of the vehicle and a future lane of travel of the vehicle based on the intersection data and the position of the vehicle. The method includes determining, by the processor, a virtual lane through the intersection, the virtual lane providing a path of travel for the vehicle from the current lane of travel to the future lane of travel. The method includes controlling, by the processor, the vehicle based on the virtual lane.

Abstract: Methods for monitoring and/or regenerating a selective catalytic reduction particulate filter (SCRF) are provided. The SCRF comprises a porous filter substrate and a catalytic composition capable of reducing NOx applied thereto. Methods include determining a SCRF pressure differential (dP) and determining the SCRF soot loading using a 1st SCRF dP map if the SCRF has not been degreened, or a 2nd SCRF dP map if the SCRF has been degreened. The SCRF has been degreened if one or more of a degreening cumulative time and temperature threshold has been achieved and a filter regeneration count threshold has been achieved. The 1st and 2nd SCRF dP maps correlate SCRF dP and one or more of SCRF temperature, exhaust mass flow, and exhaust volumetric flow to a SCRF soot loading. The method can optionally further include initiating a filter regeneration if the determined SCRF soot loading is above a soot loading threshold.
