Patent number: 11914367Abstract: Sun-aware routing and controls of an autonomous vehicle is described herein. A location and an orientation of a sensor system is identified within an environment of the autonomous vehicle to determine whether the sun causes a threshold level of perception degradation to the sensor system incident to generating a sensor signal indicative of a traffic light. The determination is based upon perception degradation data that can be precomputed for locations and orientations within the environment for dates and times of day. The perception degradation data is based upon the location of at least one traffic light and positions of the sun relative to the locations and the orientations within the environment. A mechanical system of the autonomous vehicle is controlled to execute a maneuver that reduces perception degradation to the sensor system when the perception degradation is determined to exceed the threshold level of perception degradation.Type: GrantFiled: December 11, 2018Date of Patent: February 27, 2024Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventor: Clement Creusot
