Claim 14:
15. A method of controlling an autonomous vehicle, comprising:
generating an initial route for the autonomous vehicle, wherein the initial route comprises potential stopping points for each traffic light along the initial route;
for each of the potential stopping points along the initial route:
identifying a location of a sensor system of the autonomous vehicle within an environment of the autonomous vehicle;
identifying a maneuver to control an orientation of the sensor sytem at the location based on perception degradation to the sensor system; and
determining the perception degradation to the sensor system caused by the sun when the sensor system generates a sensor signal indicative of a traffic light at the location, wherein the determination is based on a date, a time of day, the location of the sensor system, and the orientation of the sensor system at the location of the sensor system within the environment of the autonomous vehicle;

generating an updated route for the autonomous vehicle and data specifying movements of the sensor system to be effectuated by an electro-mechanical device to modify a field of view of the sensor system along the updated route such that the updated route and the movements of the sensor system to modify the field of view of the sensor system along the updated route causes the sensor system to avoid the potential stopping points having perception degradation to the sensor system exceeding a threshold level of perception degradation;
controlling a mechanical system of the autonomous vehicle to cause the autonomous vehicle to traverse along the updated route; and
controlling the electro-mechanical device to move the sensor system with respect to the autonomous vehicle to modify the field of view of the sensor system based on the data specifying the movements of the sensor system as the autonomous vehicle traverses along the updated route.
