High definition map and route storage management system for autonomous vehicles

One or more non-transitory computer-readable storage media having instructions stored thereon that, in response to being executed by one or more processors, cause a system to perform operations comprising:

• storing, by a vehicle, a plurality of map tiles, each map tile representing a portion of Hight Definition (HD) map data;
• determining a location of the vehicle based on sensor data;
• predicting movement of the vehicle within a threshold time interval from the location;
• determining a subset of map tiles based on the location and the predicted movement, each map tile of the subset of map tiles corresponding to a portion of a route that the vehicle is likely to drive through within the threshold time interval;
• loading the subset of map tiles in the RAM;
• and
• providing access to the subset of map tiles loaded in the RAM during navigation of the vehicle along the route.
