  • Publication number: 20220410901
    Abstract: A method of initializing an automatic lane change in a moving primary automobile, including categorizing, via a controller within the primary automobile, a moving automobile that is in front of the primary automobile as a target automobile, categorizing, via the controller within the primary automobile, an object in front of both the primary automobile and the target automobile as one of a low confidence object and a high confidence object, initializing, via the controller within the primary automobile, the automatic lane change for the primary automobile when the object is categorized as a high confidence object, and initializing, via the controller within the primary automobile, the automatic lane change for the primary automobile when the object is categorized as a low confidence object and a lane change of the target automobile is detected by at least one of a plurality of sensors within the automobile.

  • Publication number: 20220306199
    Abstract: Systems and methods for smoothing automated lane change (ALC) operations. A mission planner, upon receipt of an ALC request, sends a ALC heads up signal to a lateral control. The mission planner then begins confidence building operations, for a preprogrammed duration of time, and awaits an ALC ready signal from the lateral control. The lateral control, upon receipt of the ALC heads up, calculates an index of readiness, RALC, as a function of the requested ALC, a current trajectory, and a lane centering control path. When RALC is less than or equal to a readiness threshold, Rt, the lateral control sends the ALC ready signal. When RALC is greater than Rt, the lateral control generates a steering correction and applies the steering correction to reduce the RALC and thereby stabilize the vehicle and send the ALC ready signal. Upon receiving the ALC ready signal, the ALC operation is executed.

  • Publication number: 20220144276
    Abstract: In accordance with an exemplary embodiment, methods and systems are provided for controlling automatic overtake functionality for a host vehicle. In on such exemplary embodiment, a disclosed method includes: (i) obtaining, via a plurality of sensors, sensor data pertaining to the host vehicle and a roadway on which the host vehicle is traveling; (ii) determining, via a processor, when an automatic overtake is recommended, using the sensor data in conjunction with one or more threshold values; (iii) receiving driver inputs pertaining to the automatic overtake; and (iv) adjusting, via the processor, the one or more threshold values for the automatic overtake based on the driver inputs.

  • Publication number: 20220111848
    Abstract: An autonomous vehicle and a system and method of operating the autonomous vehicle. The system includes a sensor and a processor. The processor determines an effective observation area of the sensor, the effective observation area being affected by an extrinsic condition. The processor determines an available time for performing a lane change based on the effective observation area and performs the lane change based on the available time.

  • Publication number: 20210380131
    Abstract: One general aspect includes a system to prevent a boxed-in driving situation, the system including: a memory configured to include one or more executable instructions and a processor configured to execute the executable instructions, where the executable instructions enable the processor to detect a preventable box-in driving situation; and, based on the detection of the preventable box-in driving situation, adjust a location of a trigger threshold along a vehicle path.

  • Publication number: 20200379465
    Abstract: A method and apparatus that adjust a field of view of a sensor are provided. The method includes detecting at least one target object in an effective field of view of the sensor, determining an area corresponding to the effective field of view of the sensor, determining whether a critical zone is within the effective field of view based on the determined area of the effective field of view, parameters corresponding to the at least one target object, and parameters corresponding to the host vehicle, and moving the host vehicle within its lane of travel to adjust the effective field of view to capture the critical zone in response to determining that the critical zone is not within the effective field of view.
