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.

Abstract: A method of controlling a color display screen aboard a motor vehicle includes performing, via a host computer, a color calibration test of a user of the motor vehicle in which the user is subjected to a calibrated set of color-coded test information. The method includes receiving a color perception response of the user to the calibrated set of color-coded test information via the host computer. Additionally, the method includes mapping a reduced visual gamut of the user via the host computer using the color perception response, and then commanding adjustment of user-specific color settings of the motor vehicle using the reduced visual gamut to thereby accommodate a color perception deficiency of the user.

Abstract: A windshield corrective optical system includes a motor vehicle having a windshield. A camera is positioned within an occupant compartment of the motor vehicle directed toward the windshield and receiving light rays passing through the windshield. A sensor is configured to receive the light rays. A corrective element is configured to allow passage of the light rays through the corrective element to the sensor. The corrective element corrects aberrations of the light rays induced by passing through the windshield prior to the light rays reaching the sensor.

Abstract: A perception system for a motor vehicle includes a camera with a lens having a field of view and configured to focus incident light from the field of view. The field of view includes a road having a road surface. The perception system also includes an imaging sensor arranged in the camera. The imaging sensor has a photosensitive surface defined by an imaging surface area configured to capture the incident light focused from the field of view. A first portion of the imaging surface area is configured to capture an image of the road. The perception system further includes a first polarizer array arranged across the first portion of the imaging surface area and configured to reduce glare from the road surface.

Abstract: A multi-directional viewing camera system for a motor vehicle including a vehicle body defining an interior compartment and a body panel having an exterior surface and an interior surface facing the interior compartment. The camera system includes a mirror module for mounting to the body panel exterior surface. The mirror module is configured to capture and transmit incident light from at least one field of view (FOV) and has a polarizing beam splitter configured to reflect an s-polarized component and transmit a p-polarized component of the incident light in a visible spectral range. The camera system also includes a camera module having a video camera for mounting to the body panel interior surface. The camera module is configured to receive from the mirror module the s-polarized or the p-polarized component of the incident light and selectively display at least one FOV within the interior compartment.

Abstract: A system to localize debris on an optical surface of a vehicle includes a first array along a first side of a perimeter of the optical surface and including a light source to emit light into a thickness of the optical surface. A second array is along a second side of the perimeter, opposite the first side, and includes a light detector to detect light scatter in the thickness and provide a corresponding output. A third array is along a third side of the perimeter and includes a light source to emit light. A fourth array is along a fourth side of the perimeter, opposite the third side, and includes a light detector to detect light scatter and provide a corresponding output. A controller identifies a presence of the debris, determines a position of the debris based on the output from the light detectors, and remediates the debris.

Abstract: A system and method of classifying an object. The system includes a polarizing beam splitter, a first detector, a second detector and a processor. The polarizing beam splitter generates a first source signal having a first polarization direction and a second source signal having a second polarization. The first detector transmits the first source signal at the object and receives a first reflected signal generated at the object in response to the first source signal. The second detector transmits the second source signal at the object and receives a second reflected signal generated at the object in response to the second source signal. The processor is configured to compare the first reflected signal to the second reflected signal to classify the object.
