Claim 10:
11. A vehicle, comprising:
an optical perception system; and
at least one processor in operable communication with the optical perception system, wherein the at least one processor is configured to execute program instructions, wherein the program instructions are configured to cause the at least one processor to:
receive optical perception data from the optical perception system of the vehicle, wherein the optical perception data includes data describing at least one detected turn indicator light of another vehicle perceived by the optical perception system including a status of the at least one detected turn indicator light;
generate a turn indicator light signal in the form of a time varying waveform based on the status of the at least one detected turn indicator light;
obtain a duty cycle and frequency of the turn indicator light signal;
assess whether the at least one detected turn indicator light is a valid detection by comparing the duty cycle and frequency with predetermined bounds; and
when the at least one detected turn indicator light is assessed to be a valid detection, then control at least one automated feature of the vehicle based on the data describing the at least one detected turn indicator light.
