Methods and systems for generating a horizon for use in advanced driver assistance system (ADAS)
First Claim
1. A method of generating a horizon for use in an advanced driver assistance system (ADAS) of a vehicle, comprising:
- obtaining data representing a pre-calculated route to be traveled by the vehicle;
determining a most probable outgoing path that the vehicle is expected to travel in the immediate future at a decision point, wherein the most probable outgoing path is an outgoing path corresponding to a portion of the pre-calculated route;
using one or more of stored digital location-based data, vehicle data and driver data to determine data indicative of a relative probability that each of one or more other outgoing paths at the decision point will be taken by the vehicle;
determining at least one alternative outgoing path that the vehicle will be expected to travel in the immediate future at the decision point based on the data indicative of the relative probability;
generating the horizon using the determined most probable outgoing path and the at least one alternative outgoing path; and
providing data associated with the generated horizon to one or more applications, the data associated with the generated horizon configured to be used by the one or more applications when controlling corresponding vehicle subsystems.

Abstract
A method of generating a horizon for use by an ADAS of a vehicle involves using digital location-based data, driver data and/or vehicle data to determine the likelihood that different outgoing paths are taken at a decision point along a currently traversed road segment, and deriving a probability that each path may be taken. The probability may be based on one or more of: an angle of the path relative to the incoming path, the road class of the path, a speed profile of the path, historical paths taken by vehicles at the decision point, and historical paths taken at the decision point by the individual driver or vehicle.

21. A system for generating a horizon for use in an advanced driver assistance system (ADAS) of a vehicle, the system comprising:
-
a processor; a memory coupled to the processor; and the processor configured to; obtain data representing a pre-calculated route to be traveled by the vehicle; determine a most probable outgoing path that the vehicle is expected to travel in the immediate future at a decision point, wherein the most probable outgoing path is an outgoing path corresponding to a portion of the pre-calculated route; use one or more of stored digital location-based data, vehicle data and driver data to determine data indicative of a relative probability that each of one or more other outgoing paths at the decision point will be taken by the vehicle; determine at least one alternative outgoing path that the vehicle will be expected to travel in the immediate future at the decision point based on the data indicative of the relative probability; generate the horizon using the determined most probable outgoing path and the at least one alternative outgoing path; and provide data associated with the generated horizon to one or more applications, the data associated with the generated horizon configured to be used by the one or more applications when controlling corresponding vehicle subsystems. - View Dependent Claims (22)
