    Abstract: A method for validating an autonomous vehicle performance using nearby traffic patterns includes receiving remote vehicle data. The remote vehicle data includes at least one remote-vehicle motion parameter about a movement of a plurality of remote vehicles during a predetermined time interval. The method further includes determining a traffic pattern of the plurality of remote vehicles using the at least one remote-vehicle motion parameter. The method includes determining a similarity between the traffic pattern of the plurality of remote vehicles and movements of the host vehicle. Further, the method includes determining whether the similarity between the traffic pattern of the plurality of remote vehicles and movements of the host vehicle is less than a predetermined threshold. Also, the method includes commanding the host vehicle to adjust the movements thereof to match the traffic pattern of the plurality of remote vehicles.

    Abstract: A vehicle system and method that can determine object sensor misalignment while a host vehicle is being driven, and can do so within a single sensor cycle through the use of stationary and moving target objects and does not require multiple sensors with overlapping fields of view. In an exemplary embodiment where the host vehicle is traveling in a generally straight line, one or more object misalignment angle(s) αo between an object axis and a sensor axis are calculated and used to determine the actual sensor misalignment angle α.
