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, R, as a function of the requested ALC, a current trajectory, and a lane centering control path. When Ris less than or equal to a readiness threshold, Rt, the lateral control sends the ALC ready signal. When Ris greater than Rt, the lateral control generates a steering correction and applies the steering correction to reduce the Rand thereby stabilize the vehicle and send the ALC ready signal. Upon receiving the ALC ready signal, the ALC operation is executed.
