Method of and system for controlling operation of self-driving car

Abstract

Method and device for controlling operation of a Self-Driving Car. The method includes determining route-level and lane-level information for generating a graph-structure, applying a first model for assigning costs to respective edges, determining scores for vertices based on the costs, storing the edges with the costs and the vertices with the scores. The method also includes at a given moment in time during operation: acquiring a lane path indicative of a lane segment extending from the current location without a lane-changing manoeuvre. The method includes, for the lane path: identifying a series of vertices covered by the lane segment, applying a second model for assigning additional costs to lane-path-departing edges of the series of vertices thereby determining locally-increased costs, determining a locally-adjusted scores for vertices in the series of vertices based on the locally-increased costs, and identifying a lane path score for the lane path based on the locally-adjusted scores.
