Abstract: An operator offset request for automatic lane following system of an automobile vehicle includes an operator offset request defining a lateral offset distance away from a first travel-line of an automobile vehicle in a displacement path moved until a second travel-line of the automobile is achieved. An operator input setting system when actuated generates an initiation signal forwarded to a controller to input the operator offset request. An achievement signal is generated to signify a selected offset position selected by a vehicle operator for the offset distance is achieved. A vehicle return travel path is elected by the vehicle operator to return the automobile vehicle to the first travel-line from the second travel-line by a return displacement path which is opposite to the displacement path.

Abstract: In various embodiments, methods, systems, and vehicle apparatuses are provided. A method for implementing a lane-keeping assist unit of a vehicle by receiving information of a plurality of road geometries, and driving scenarios wherein at least one driving scenario is combined with a target path that is parallel and biased from a lane center by a desired path offset, and a reference path for guiding the vehicle to merge with the target path; adapting the reference path with control based on a selected road geometry and driving scenario; adjusting the desired path offset by considering lane markings during an intervention for an inner curve, an outer curve and a straight road; controlling the vehicle trajectory for enabling the vehicle to track the reference path; exiting the intervention once a trajectory tracking performance by the vehicle is confirmed; and aborting once an instability of the trajectory tracking performance is confirmed.

Abstract: In an exemplary embodiment, a vehicle system is provided that includes a sensor array and a processor. The sensor array is configured to generate vehicle sensor data pertaining to a target vehicle in proximity to the vehicle. The processor is coupled to the sensor array, and is configured to at least facilitate: beginning an overtake maneuver for the vehicle, via instructions provided to the drive system, when conditions for an overtake of the target vehicle by the vehicle are initially determined by the processor to be valid; subsequent to the beginning of the overtake maneuver, determining via the processor whether the conditions for the overtake of the target vehicle are still valid, based on updated sensor data reflecting variant traffic conditions; and further controlling the overtake maneuver based on the determining as to whether the conditions for the overtake of the target vehicle are still valid.

Abstract: A method is provided for autonomously operating a vehicle. The method includes receiving vehicle state and vehicle environment data; determining that a vehicle position is not in a position for autonomous mode based on vehicle state and vehicle environment data, wherein the position is associated with a center of one lane of a roadway; enabling a steering assistance torque for a lane-centering operation concurrently within a pre-determined period of time of engagement of the autonomous mode for a vehicular operation; blending the steering assistance torque for assisting in vehicle guidance with a torque applied by the operator for the lane-centering operation with the autonomous mode of vehicular operation engaged; and executing enablement of the autonomous vehicular operation mode with the vehicle positioned within the center of one lane of the roadway as the operator is transitioned from a hands-on to a hands-off control of the vehicle.

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.

Abstract: A method of providing a collision warning within a vehicle comprises detecting an object and determining the distance to the object, identifying when a driver is distracted and measuring the time that the driver has been distracted, calculating an actual time to collision, modifying first and second pre-determined time to collision thresholds based on information from the driver monitoring system and creating first and second modified time to collision thresholds, comparing the actual time to collision to the first and second modified time to collision thresholds, sending a signal to a driver interface to provide an initial warning to the driver when the actual time to collision is less than the first modified time to collision threshold, and sending a signal to the driver interface to provide an imminent collision warning to the driver when the actual time to collision is less than the second modified time to collision threshold.
