Abstract

A system and method to distinguish between a lane change and a turn of a vehicle as an intended movement of the vehicle based on a driver-initiated motion toward an adjacent lane that is adjacent to a lane occupied by the vehicle include obtaining input from one or more sources. The one or more sources include a sensor system or a communication system. The method also includes processing the input from the one or more sources to obtain indirect information that indicates a direction of travel in the lane adjacent or to obtain direct information specific to a location of the vehicle, determining whether the lane change or the turn is more likely to be the intended movement based on the indirect information or the direct information, and modifying an action of a vehicle system based on the determining whether the lane change or the turn is more likely.

First claim

What is claimed is:

1. A method of distinguishing between a lane change and a turn of a vehicle as an intended movement of the vehicle based on a driver-initiated motion by a driver of the vehicle toward an adjacent lane that is adjacent to a lane occupied by the vehicle, the method comprising:
obtaining input from one or more sources, the one or more sources including a sensor system or a communication system;
processing the input from the one or more sources to obtain indirect information that indicates a direction of travel in the adjacent lane or to obtain direct information specific to a location of the vehicle;
determining whether the lane change or the turn is more likely to be the intended movement of the driver of the vehicle based on the indirect information or the direct information; and
modifying an action of a vehicle system based on the determining whether the lane change or the turn is more likely, wherein obtaining the indirect information includes determining whether a distance between the vehicle and a double line or double-dashed line is more than a lane width such that another lane separates the vehicle from the double line or the double-dashed line.

2. The method according to claim 1 , wherein the modifying the action of the vehicle system includes modifying a warning provided through an infotainment system.

3. A system to distinguish between a lane change and a turn of a vehicle as an intended movement of the vehicle based on a driver-initiated motion of a driver of the vehicle toward an adjacent lane that is adjacent to a lane occupied by the vehicle, the system comprising:
one or more sources configured to provide input, wherein the one or more sources include a sensor system or a communication system;
a controller configured to process the input from the one or more sources to obtain indirect information that indicates a direction of travel in the adjacent lane or to obtain direct information specific to a location of the vehicle and determine whether the lane change or the turn is more likely to be the intended movement of the driver of the vehicle based on the indirect information or the direct information, wherein the controller modifies an action of a vehicle system based on determining whether the lane change or the turn is more likely, wherein the controller is configured to obtain the indirect information based on determining whether a distance between the vehicle and a double line or double-dashed line is more than a lane width such that another lane separates the vehicle from the double line or the double-dashed line.

4. The system according to claim 3 , wherein the controller is configured to modify the action of the vehicle system by modifying a warning provided through an infotainment system.
