  • Patent number: 11390285
    Abstract: An automated lane change system for a motor vehicle includes one or more environmental sensors for generating an input signal indicative of a position of an object relative to the motor vehicle, with the object being disposed at a distance from the motor vehicle. The input signal is further indicative of a velocity of the object relative to the motor vehicle. The system further includes a steering wheel sensor generating a gripped signal, in response to a driver gripping a steering wheel. A controller generates an activation signal, in response to the controller receiving the input signal from the environmental sensor and the gripped signal from the steering wheel sensor. An actuator controls the steering wheel, a propulsion mechanism, and a braking mechanism for maneuvering the motor vehicle from a current driving lane to a target driving lane, in response to the actuator receiving the activation signal from the controller.

  • 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: 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.
