Problems solved by technology
For example, when the lead vehicle is too close to the host vehicle, due to traffic jams or other traffic conditions, the camera may not detect lane markings because the signs are obscured by the lead vehicle, and lane marking detection for the lane will thus fail
Likewise, other techniques such as following the lead vehicle that have proven useful will fail if there is no lead vehicle to follow on an empty road, or if the lead vehicle is making a lane change

Embodiment Construction
[0047] The following discussion of embodiments of the present invention, directed to systems and methods for detecting vehicle road lanes on which a vehicle is traveling, is exemplary only and in no way intended to limit the invention or its application or use.
[0048] The present invention proposes a system and method for accurately detecting a vehicle's driving lane, wherein the vehicle includes sensors that provide sensor data including lane information to a lane detection subsystem. The lane detection subsystem provides estimated lanes and corresponding confidence information. For example, the estimated lane processor may detect lanes based on lane markings, leading vehicles, or lane level accuracy GPS / maps. The estimated lane and corresponding confidence information are combined to give a detected lane, and are used to tune the vehicle to improve the accuracy of the next estimated lane and confidence information.

The invention relates to a lane sensing enhancement through object vehicle information for lane centering / keeping. A system and method for accurately estimating a lane in which a vehicle is traveling. A sensor mounted on the vehicle generates sensor data including lane information that is processed by several lane detection sub-systems to generate two or more estimated lanes with corresponding lane confidence information. A combining processor combines the estimated lanes based upon the confidence information to determine a combined estimated lane.
Description
technical field [0001] The present invention relates generally to a system and method for detecting a road lane in which a vehicle is traveling, and more particularly to a method that includes processing sensor data in various ways to estimate lanes and identify corresponding confidence information and then use the confidence information to combine Systems and methods for detecting road lanes on which a vehicle is traveling, each estimating lanes to detect road lanes. Background technique [0002] Modern vehicles are becoming more and more autonomous, ie, the vehicle is able to provide driving control with less driver intervention. Cruise control systems have existed on vehicles for many years, wherein the vehicle operator is able to set a specific speed of the vehicle and the vehicle will maintain that speed without the driver manipulating the throttle. Adaptive cruise control systems have been developed more recently in the art, wherein the system not only maintains a set...
