Abstract: In exemplary embodiments, methods and systems are provided for controlling an auto high beam functionality for headlights of a vehicle. In an exemplary embodiment, a method includes: obtaining camera data pertaining to an object in front of the vehicle; identifying, via a processor, a radial gradient of pixels in a region of interest from the camera data; and automatically controlling, via the processor, the auto high beam functionality for the headlights based on the radial gradient.

Abstract: Systems and methods of detecting and validating a turn light indicator in a vehicle include receiving optical perception data from an optical perception system. The optical perception data includes data describing a detected turn indicator light of another vehicle perceived by the optical perception system including a status of the detected turn indicator light. A turn indicator light signal is generated in the form of a time varying waveform based on the status of the detected turn indicator light. A duty cycle and frequency of the turn indicator light signal is obtained. An assessment is made whether the detected turn indicator light is a valid detection by comparing the duty cycle and frequency with predetermined bounds. When the detected turn indicator light is assessed to be a valid detection, then an automated feature of the vehicle is controlled based on the data describing the detected turn indicator light.
