Abstract: A system for automatedly changing a first road lane of a vehicle to a second road lane to maintain engagement of an automated driving unit. The system comprises an ECU to check a location of the vehicle, defining a map segment of the first and second road lanes. The first road lane is a host lane that the vehicle occupies and the second road lane is an available lane. The ECU detects whether the first road lane has poor availability. The system further comprises a sensor to monitor availability of the first road lane. The system further comprises a backoffice to flag the first road lane if the first road lane is detected to have poor availability, to log the first road lane in an instance counter (IC), and to designate the first road lane as non-preferred if an occurrence threshold of the IC is reached. The system further comprises an automated lane change (ALC) unit to move the vehicle to the second road lane.

Abstract: Vehicles and related systems and methods are provided for controlling a vehicle in an autonomous operating mode. One method involves identifying a stationary object outside a current lane of travel based at least in part on sensor data captured onboard the vehicle, determining an estimated location for the stationary object based at least in part on the sensor data and a location of the vehicle and providing the estimated location to a remote system. The remote system updates lane preference information corresponding to the estimated location for the stationary object when the stationary object satisfies one or more avoidance criteria. The method continues by determining a trajectory for a vehicle to change lanes based at least in part on the updated lane preference information and autonomously operating one or more actuators onboard the vehicle in accordance with the trajectory.
