  • Patent number: 10997431
    Abstract: Examples of techniques for controlling a vehicle using an anchor line are disclosed. In one example implementation, a computer-implemented method includes receiving a lane line quality indicator from a camera associated with a vehicle. The method further includes determining a lane line weight. The method further includes comparing the lane line quality indicator to a quality threshold to determine whether the lane line is of sufficient quality to use as an anchor line. The method further includes comparing the lane line weight to a confidence threshold to determine whether the lane line is of sufficient confidence to use as the anchor line. The method further includes, responsive to determining that at least one of the lane line is not of sufficient quality and the lane line is not of sufficient weight, generating an alternate anchor line. The method further includes controlling the vehicle using the alternate anchor line.

  • Publication number: 20210122379
    Abstract: A control system for a vehicle using a forward-facing camera includes a look ahead module configured to determine a distance to a look ahead point. A lane center module determines a location of a lane center line. A vehicle center line module determines a location of a vehicle center line. A first lateral offset module determines a first lateral offset based on the look ahead point and the determined lane center line. A second lateral offset module determines a second lateral offset based on the determined lane center line and the vehicle center line. A yaw angle offset calculating module receives the first lateral offset, the second lateral offset and the distance to the look ahead point, calculates a yaw angle offset, and compensates a yaw angle error based on the yaw angle offset.

  • Publication number: 20210061270
    Abstract: The present application relates to a method and apparatus for real time lateral control and steering actuation assessment for a motor vehicle by determining a desired host vehicle path, establishing a control point along the host vehicle path, generating a motion path between a host vehicle location and the control point, estimating a theoretical acceleration of the host vehicle along the motion path, controlling the host vehicle along the motion path, receiving a measured acceleration from an inertial measurement unit within the host vehicle, generating an error term in response to a comparison of the motion path and the measured lateral travel, and adjusting the performance limits of the sub-features in response to the error term.

  • Publication number: 20200391746
    Abstract: A vehicle, system and method for operating the vehicle is disclose. The system includes a radar system and a processor. The radar system locates a gap between targets in a second lane adjoining a first lane, with the host vehicle residing in the first lane. The processor is configured to determine a viability value of the gap for a lane change, select the gap based on the viability value, align the host vehicle with the selected gap, and merge the host vehicle from the first lane into the selected gap in the second lane.

  • Publication number: 20200361471
    Abstract: A host vehicle that includes an autonomous control system that is capable of executing an automatic lane change (ALC) maneuver is described. The ALC maneuver may be executed when the host vehicle is seeking to merge into a lane of travel. This includes operating under conditions that include moderate to heavy levels of traffic. The host vehicle is capable of soliciting a desired gap in a target lane by using a lane centering offset maneuver to influence and observe proximal vehicles operating in the target lane before executing the ALC maneuver.

  • Patent number: 10678263
    Abstract: A method and apparatus for determining a route of a vehicle are provided. The method includes activating fail operative steering in response to detecting an electronic power steering (EPS) failure, determining a length of a lane map fusion ring, calculating a desired route based on a line of the lane map fusion ring if the determined length is greater than a first predetermined distance, and calculating desired route based on offset information and heading information of the lane map fusion ring and curvature information and curvature derivative information calculated from map data if the determined length is less than the first predetermined distance.

  • Publication number: 20200062252
    Abstract: The present application generally relates to vehicle control systems and an apparatus and methods to detect diagonal lane markers. In particular, the method detects a first and second lane marker, compares those lane markers against expected lane marker values. If one of the detected lane markers deviates from an expected value by an amount greater than a threshold, the method is operative to determine if a previous lane marker detection was within the threshold and to generate a vehicle trajectory in response to the non-deviating marker and an expected marker.
