Abstract: Powerflow is managed using a method, e.g., in a powertrain system having a multi-pack rechargeable energy storage system (RESS) with parallel battery packs. Each pack has a corresponding maximum electrical (current or voltage) limit. The method includes predicting a corresponding terminal voltage for each pack using the corresponding maximum electrical limit. The method includes selecting a terminal voltage as a selected voltage based on a requested operating mode, including selecting a maximum of the terminal voltages when the requested operating mode is a discharging mode and a minimum of the same when the requested operating mode is a charging mode. A pack current through each pack is predicted using the selected voltage and a corresponding battery state space model. A total power capability of the RESS is predicted over a predetermined prediction horizon using the selected voltage, with the operating mode controlled over the prediction horizon via the controller.

Abstract: Methods and systems for enhanced object tracking by receiving sensor fusion data related to target objects and object tracks; determining splines representing trajectories of each target object; filtering the sensor fusion data about each target object based on a first, second and third filtering model wherein each filtering model corresponds to one or more of a set of hypotheses used for processing vectors related to trajectories of a track object wherein the set of hypotheses comprise: a path constraint, a path unconstrained, and a stationary hypothesis; and generating a hypothesis probability for determining whether to use a particular hypothesis based wherein the hypothesis probability is determined based on results from the first, second and third filtering models and from results from classifying, by at least one classification model, one or more features related to the object track for the target object.
Abstract: A fluid management system, or flow control system, for an automotive propulsion system is provided. The system includes a housing defining a sump configured to collect a volume of liquid and gaseous fluid and a pump configured to pump fluid from the sump. The pump defines a pump inlet and a pump outlet. A conduit is in fluid communication with the pump outlet. A passive valve is disposed within the conduit, the conduit defining a conduit outlet downstream of the passive valve, and the conduit further defining an orifice between the pump and the passive valve. The passive valve allows hydraulic fluid to flow past the valve, while substantially preventing air from flowing past the passive valve. The air is instead bled out through the orifice, along with some of the hydraulic fluid.

Abstract: The vehicle mounted perception sensor gathers environment perception data from a scene using first and second heterogeneous (different modality) sensors, at least one of the heterogeneous sensors is directable to a predetermined region of interest. A perception processor receives the environment percpetion data and performs object recognition to identify objects each with a computed confidence score. The processor assesses the confidence score vis-à-vis a predetermined threshold, and based on that assessment, generates an attention signal to redirect the one of the heterogeneous sensors to a region of interest identified by the other heterogeneous sensor. In this way information from one sensor primes the other sensor to increase accuracy and provide deeper knowledge about the scene and thus do a better job of object tracking in vehicular applications.

Abstract: A method of forming a self-cleaning film system includes depositing a photocatalytic material onto a substrate to form a first layer. The method also includes disposing a photoresist onto the first layer and then exposing the photoresist to light so that the photoresist has a developed portion and an undeveloped portion. The method includes removing the undeveloped portion so that the developed portion protrudes from the first layer. After removing, the method includes depositing a perfluorocarbon siloxane polymer onto the first layer to surround and contact the developed portion. After depositing the perfluorocarbon siloxane polymer, the method includes removing the developed portion to thereby form the self-cleaning film system.

Abstract: A vehicle radar system and calibration method that provide for system calibration so that target object parameters can be calculated with improved accuracy. Generally speaking, the calibration method uses a number of hypothesized calibration matrices, which represent educated guesses for possible system or array calibrations, to obtain a number of beamforming images. A blurring metric is then derived for each beamforming image, where the blurring metric is generally representative of the quality or resolution of the beamforming image. The method then selects hypothesized calibration matrices based on their blurring metrics, where the selected matrices are associated with the blurring metrics having the best beamforming image resolution (e.g., the least amount of image blurriness). The selected hypothesized calibration matrices are then used to generate new calibration matrices, which in turn can be used to calibrate the vehicle radar system so that more accurate target object parameters can be obtained.
