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: Vehicles and related systems and methods are provided for controlling a vehicle in an autonomous operating mode. One method involves obtaining navigation information for a route for the vehicle from a navigation system, transforming the navigation information into data points defining an upcoming trajectory of the route, mapping the data points to a corresponding mapped set of lane segments encompassing one or more of the data points, assigning lane preference indicia to the mapped set of lane segments, and autonomously operating one or more actuators onboard the vehicle to laterally maneuver the vehicle into one or more lanes at respective longitudinal positions along the route corresponding to one or more lane segments of the mapped set of lane segments in a manner that is influenced by the lane preference indicia assigned to the lane segments.

Abstract: A system and method for locating a traffic light at a host vehicle. A probe vehicle obtains image data on an intersection that includes the traffic light when the probe vehicle is at the intersection and identifies the traffic light in the intersection from the data. A remote processor creates an observed node in a digital map corresponding to the traffic light and updates a mapped position of a mapped node within the digital map based on an observed position of the observed node. The host vehicle uses the mapped node of the digital map to locate the traffic light when the host vehicle is at the intersection.
