Abstract: A method of planning a path for a vehicle. The method includes receiving perception images of an area surrounding the vehicle with at least one sensor and detecting at least one perception task from the perception images with the at least one perception task identifying at least one neighboring vehicle. The method calculates a risk factor for the at least one neighboring vehicle by recognizing a behavior of the at least one neighboring vehicle from the perception images and plans the path for the vehicle based on the at least one perception task and the risk factor. The path is then executed for the vehicle.

Abstract: A detection system for a host vehicle includes a camera, global positioning system (“GPS”) receiver, compass, and electronic control unit (“ECU”). The camera collects polarimetric image data forming an imaged drive scene inclusive of a road surface illuminated by the Sun. The GPS receiver outputs a present location of the vehicle as a date-and-time-stamped coordinate set. The compass provides a directional heading of the vehicle. The ECU determines the Sun's location relative to the vehicle and camera using an input data set, including the present location and directional heading. The ECU also detects a specular reflecting area or areas on the road surface using the polarimetric image data and Sun's location, with the specular reflecting area(s) forming an output data set. The ECU then executes a control action aboard the host vehicle in response to the output data set.

Abstract: An optical system, and method related thereto, includes a camera configured to capture images. The camera has an adaptive aperture plane configured to change both an aperture size and an aperture shape in response to an aperture signal. The camera also includes a first polarized surface and second polarized surface positioned relative to the adaptive aperture plane, such that light strikes the first polarized surface, the adaptive aperture plane, then the second polarized surface. First and second lenses may be located on opposite sides of the adaptive aperture plane. An image sensor is beyond the second polarized surface and configured to output image signals, and a processor is configured to execute image perception algorithms based on the image signals. The image perception algorithms alter the aperture size and the aperture shape by sending an aperture signal from the processor to the camera for subsequent captured images.

Abstract: A visual perception system includes a scanning camera, color sensor with color filter array (CFA), and a classifier node. The camera captures full color pixel images of a target object, e.g., a traffic light, and processes the pixel images through a narrow band pass filter (BPF), such that the narrow BPF outputs monochromatic images of the target object. The color sensor and CFA receive the monochromatic images. The color sensor has at least three color channels each corresponding to different colors of spectral data in the monochromatic images. The classifier node uses a predetermined classification decision tree to classify constituent pixels of the monochromatic images into different color bins as a corresponding color of interest. The color of interest may be used to perform a control action, e.g., via an automated driver assist system (ADAS) control unit or an indicator device.

Abstract: Systems and methods in a vehicle involve transmitting light with an initial polarization from a lidar system, and controlling an external compensator, external to the lidar system, or an internal compensator within the lidar system to change the initial polarization of the light to a new polarization of the light. The method also includes receiving reflected light resulting from reflection of the light from one or more objects, and obtaining information about the one or more objects based on the reflected light.

Abstract: System and method of controlling operation of an optical sensor in a device. The optical sensor is configured to employ a scan pattern to scan respective portions of a full field of view. A navigation sensor is configured to obtain location coordinates of the device. An inertial sensor is configured to obtain an acceleration data of the device in a plurality of directions. A controller is configured to determine a position of the device at the present time based in part on the location coordinates and the acceleration data. The controller is configured to determine a sun striking zone based in part on a relative position of the sun and the device. When a sun overlap region between the respective portions of the full field of view and sun striking zone exceeds a first overlap threshold, operation of the optical sensor is modified.

Abstract: An automobile includes an electronic control unit (ECU), at least one fiber optical cable, and a sensor unit. The ECU is operational to generate an optical power signal and a first optical communications signal. The fiber optical cable transports the optical power signal and the first optical communications signal. The sensor unit is operational to convert the optical power signal into an electrical power, convert the first optical communications signal into an electrical control signal, measure a first parameter related to the automobile, and generate a second optical communications signal that conveys the first parameter as measured. The fiber optical transports the second optical communications signal to the electronic control unit. The ECU is further operational to convert the second optical communications signal into a first electrical sensed signal that conveys the first parameter, and take an action based on the first parameter in the first electrical sensed signal.

Abstract: A system for a host vehicle operating on a road surface includes a polarimetric camera, a global positioning system (“GPS”) receiver, a compass, and an electronic control unit (“ECU”). The camera collects polarimetric image data of a drive scene, including a potential driving path on the road surface. The ECU receives the polarimetric image data, estimates the Sun location using the GPS receiver and compass, and computes an ideal representation of the road surface using the Sun location. The ECU normalizes the polarimetric image data such that the road surface has a normalized representation in the drive scene, i.e., an angle of linear polarization (“AoLP”) and degree of linear polarization (“DoLP”) equal predetermined fixed values. The ECU executes a control action using the normalized representation.
