Detecting and resolving disparities between map data and environments perceived by sensor systems

This invention describes a system that helps keep digital maps accurate for vehicles. It works by having a vehicle's sensors observe the real world and compare what they see with existing map data. If there's a difference, like a new road sign or construction, the system figures out why and then updates the map or adjusts how other vehicles' sensors interpret the environment. The claims specifically describe a system for vehicles that can also lock portions of map data to prevent unauthorized changes.
