    Abstract: In an exemplary embodiment, a system is provided that includes one or more first sensors, one or more second sensors, and a processor disposed onboard a vehicle. The first sensors are configured to at least facilitate obtaining first sensor data with regard to an external environment outside the vehicle. The second sensors are configured to at least facilitate obtaining second sensor data with regard to one or more eyes of a driver of the vehicle. The processor is configured to at least facilitate: determining a predicted gaze angle of the one or more eyes of the driver based on the external environment outside the vehicle, using the first sensor data; determining a measured gaze angle of the one or more eyes of the driver, using the second sensor data, and controlling one or more vehicle actions based on a comparison of the predicted and measured gaze angles.

    Abstract: Operation of a vehicle that includes an autonomous operating system including an on-board map database includes operating in a travel lane employing a lane keeping control system and an adaptive cruise control system and monitoring a plurality of lane reference markers. Periodically, parameters are determined, including a first lateral offset for the vehicle based upon a forward-monitoring sensor and one of the lane reference markers, and a second lateral offset for the vehicle based upon a GPS sensor and the map database. A difference and an associated variance are determined, and an error in the map database is determined when the variance is greater than a threshold variance. The vehicle operator is alerted to actively control the vehicle based upon the detected error in the map database.

    Abstract: Methods and apparatus provided for determining a current position of a vehicle are disclosed. The apparatus includes an autonomous driving system for a vehicle with a positioning system configured to determine a current position of the vehicle between an original point of the vehicle and a horizon point ahead the vehicle. The positioning system is configured to receive map data containing at least one road attribute, receive multiple trajectory points which are located between the original point and the horizon point and determine a trajectory which interconnects the multiple trajectory points, determine an absolute position of the vehicle, determine a projection point from the at least one road attribute onto the trajectory, and determine the current position of the vehicle and compare the current position of the vehicle with a position of the projection point of the road attribute between the original point and the horizon point.

    Abstract: A lane detection method includes: identifying locations of a lane line included in a first image captured using a first camera capturing images beside the vehicle, the first camera being mounted to a mirror that is movable; based on the locations of the lane line, determining a first linear equation corresponding to the lane line; determining a distance to the lane line based on the first linear equation; identifying locations of the lane line included in a second image captured using a second camera capturing images in front of the vehicle; based on the locations of the lane line, determining a second linear equation corresponding to the lane line; based on the first and second linear equations, determining an angle between first and second lines corresponding to the first and second linear equations, respectively; and determining a corrected distance to the lane line based on the distance and the angle.
