Abstract: One general aspect includes a system to commence host vehicle movement upon being stopped behind a target vehicle, the system includes a memory configured to include one or more executable instructions and a processor configured to execute the executable instructions, where the executable instructions enable the processor to: detect the target vehicle as being stopped along a route; cause the host vehicle to stop at a first distance from the target vehicle; detect a transition of one or more brake lights of the target vehicle from an ON state to an OFF state; and after the one or more brake lights are detected to transition from the ON state to the OFF state, cause the host vehicle to move at a slow speed in the direction of the target vehicle.

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.
