Abstract: A system for an attention-based perception includes a camera device configured to provide an image of an operating environment of a vehicle. The system further includes a computerized device monitoring the image, analyzing sensor data to identify a feature in the image as corresponding to an object in the operating environment and assign a score for the feature based upon an identification, a location, or a behavior of the object. The computerized device is further operable to define candidate regions of interest upon the image, correlate the score for the feature to the candidate regions of interest to accrue a total region score, select some of the candidate regions for analysis based upon the total region scores, and analyze the portion of the candidate regions to generate a path of travel output. The system further includes a device controlling the vehicle based upon the output.

Abstract: An electric powertrain includes a sensor-controller interface, an inverter-controller electrically connected to the battery pack, and an electric machine connected to the inverter-controller and having a rotor with an angular position. The rotor powers a driven load at a torque and/or speed level controlled by the inverter-controller in response to position signals indicative of the angular position. A rotary position sensor is operatively connected to the rotor to generate and output the position signals. The sensor derives the position signals from unmodulated sine and cosine signals, and communicates the position signals and a binary sensor state of health (SOH) to the inverter-controller over the interface. The inverter-controller also decodes the position signals and the binary sensor SOH to generate decoded control data, and controls the torque and/or speed level using the decoded control data.

Abstract: A vehicle communication and control system includes a servicing host capable of exchanging data with a vehicle. The servicing host provides a vehicle service and includes a service identifier (ID) that indicates the vehicle service. The vehicle is configured to actively detect the service ID and to determine the vehicle service in response to detecting the service ID. The vehicle and the servicing host establish a wireless connection to exchange data and automatically initiate the vehicle service in response to detecting the service ID.

Abstract: In various embodiments, cameras and mobile platforms are provided. In one exemplary embodiment, a mobile platform is provided that includes a body and a camera disposed on the body. The camera includes one or more image sensors, and one or more lens assemblies. The one or more lens assemblies are configured with respect to the one or more image sensors, that at least one image plane from the one or more image sensors is tilted to form a non-zero angle with at least one equivalent lens plane from the one or more lens assemblies, transferring the image focal plane to be parallel to the movement direction of the mobile platform in which the camera is installed. The use of multiple image sensors or lens assemblies in certain embodiments increases camera angle of view.

Abstract: A system and method for obtaining an overall image that is constructed from multiple sub-images. The method includes: capturing a first sub-image having a first sub-image field of view using an image sensor of an electronically-steerable optical sensor; after capturing the first sub-image, steering light received at the electronically-steerable optical sensor using an electronically-controllable light-steering mechanism of the electronically-steerable optical sensor so as to obtain a second sub-image field of view; capturing a second sub-image having the second sub-image field of view using the image sensor of the electronically-steerable optical sensor; and combining the first sub-image and the second sub-image so as to obtain the overall image.
