Method and system for providing an electronic horizon in an advanced driver assistance system architecture

A software program installed in a motor vehicle that provides data about a road network around the motor vehicle comprising:

• a programming routine that accesses data that represent roads located around a current vehicle position;
• a programming routine that determines which roads located around the current vehicle position are paths along which the motor vehicle can travel from said current position out to an extent associated with a threshold;
• and
• a programming routine that stores data defining said paths in a temporary data repository from which other applications can obtain said data defining said paths.

A method performed by a software program installed in a motor vehicle to provide data about a road network around a motor vehicle comprising the steps of:

• determining a plurality of paths that the motor vehicle can travel from a current location out to an extent associated with a threshold,
• wherein each path is comprised of a different sequence of one or more road segments,
• and wherein each sequence begins with the road segment upon which the motor vehicle is located,
• and wherein the roads segments in each sequence form a continuous path along which the motor vehicle can travel from the current location out to said extent, and
• providing data defining the sequence of road segments in each of said plurality of paths for use by other applications in said motor vehicle.
