Abstract: A system and method are provided for operating an autonomous or semi-autonomous host vehicle. The method includes receiving data measured from a plurality of sensors, wherein the measured data relates to one or more target vehicles in the host vehicle's field of view, calculating a desired speed command based on a driver-selected set-speed and the measured data, detecting initiation of a host vehicle lane change to a desired adjacent lane, and in response to initiation of the lane change, selecting an acceleration profile based on at least one set of operating conditions, calculating a modified speed command by adjusting the desired speed command according to the selected acceleration profile; and controlling a host vehicle speed based on the modified speed command.

Abstract: The methods and system described herein may be used to assist an automated driving system of a host vehicle. The methods and system may, in an exemplary embodiment, be used to determine whether a host vehicle or a target vehicle is cutting out and, accordingly, control the acceleration and/or other driving features of the host vehicle. Generally, the methods described herein contain the steps of determining that a vehicle is cutting out, determining which vehicle is cutting out, and then controlling the acceleration of the host vehicle based on the previous determinations. The determination of which vehicle is cutting out is made based on readings gathered by the host vehicle from one or more automated driving sensors. By using target vehicle sensor data in conjunction with lane marking sensor data, the host vehicle can determine, not only that a vehicle is cutting out, but which vehicle(s) are cutting out.
