Abstract: A method of controlling an autonomous vehicle, which is movable on a surface, includes obtaining a model (world model) of the surface, by which each area of the surface is associated with a probabilistic occupancy score; determining, on the basis of the area's position, an occupancy threshold to be applied to an area of the surface; enabling movement of the AV into the area if the associated occupancy score is less than the determined occupancy threshold; and otherwise disabling movement into the area. In one embodiment, where the model is obtained or updated based on measurement data from one or more sensors carried by the autonomous vehicle, the occupancy threshold is determined to be relatively lower if the area is outside a field of view of the sensors carried by the AV and relatively higher if the area is inside the field of view.
