Method of representing road lanes
First Claim
Patent Images
1. A method comprising:
- storing, in a navigation database, at least one data representation of a road lane including a boundary for the road lane and an adjacency attribute for the at least one data representation of the road lane, wherein the adjacency attribute for the road lane describes at least one feature adjacent to the road lane and outside of the boundary for the road lane;
receiving, at a driving assistance system, data from one or more sensors of a vehicle;
accessing, from the navigation database, the adjacency attribute for the at least one data representation of the road lane; and
generating data indicative of an action for the driving assistance system in response to the adjacency attribute accessed from the navigation database.

Abstract
A method is disclosed for representing road lanes as data in a database that can be used by a system in a vehicle to provide a safety-related function. Each data representation of a physical road lane includes data indicating start and end points of the represented lane and other data attributes pertaining to the represented lane, including data indicating what physical features are adjacent to the represented lane on right and left sides thereof and data indicating a geometry of the represented lane. The database is compatible with navigation-related applications that use a different data model to provide navigation-related functions.
