Method and apparatus are disclosed for controlling window tint levels to protect the interior cabin of an autonomous vehicle. An example vehicle includes photochromic windows and a processor. The processor determines a sun profile based on images of an area external to the vehicle captured by a camera. The processor also determines a protection mode to reduce a current sun projection on an interior of the vehicle based on the sun profile. The processor also individually sets tint levels on the photochromic windows based on the determined protection mode.
