Abstract

The present invention relates to a system and a method of steering override end detection for automated lane centering. A method and system may measure one or more vehicle steering measurements or quantities and calculate one or more expected vehicle steering measurements. The method and system may deactivate an automatic vehicle control system based on the one or more measured vehicle steering measurements and the one or more expected vehicle steering measurements. The vehicle steering measurements may include a vehicle steering angle measurement, vehicle steering torque measurement, or other vehicle dynamics measurements. The automatic vehicle control system may include an automated lane centering system, lane keeping assist, or other autonomous vehicle steering control system.

Description

technical field [0001] The present invention relates to methods and systems for determining override events for an automated steering system or method, using a combination of, for example, steering angle, steering torque, and other data. Background technique [0002] Many vehicles are equipped with automatic and / or semi-autonomous driving systems, applications, and / or features. Automatic and / or semi-autonomous driving systems may provide automated driving controls that reduce the amount of driver action required to operate the vehicle. Automatic lane centering methods, features and applications, for example, can be initiated by the driver while the vehicle is in motion and can maintain the vehicle's position in the center of the lane. Adaptive lane centering systems that maintain a fixed lane offset, or position of the vehicle relative to the lane on the road the vehicle is traveling on. Adaptive lane centering systems maintain the vehicle's position relative to the road w...
