Abstract

In one embodiment, autonomous driving control is provided for an autonomous vehicle changing from a source lane to a target lane. Using a topological map, a reference node is selected in the source lane. With respect to the reference node, an earliest node is determined in the source lane at which it is first possible for the vehicle to change lanes and a last node is determined in the source lane after which it is no longer possible to change lanes. A range of the source lane is determined for which the vehicle can change lanes.
