1. A method for use with an automated driving system installed on a host vehicle, the automated driving system comprises one or more automated driving sensor(s) and an automated driving control unit, and the method comprises the steps of:

  • gathering target vehicle readings and lane marking readings from the one or more automated driving sensor(s);

    determining a relative lateral position (xlat) of the host vehicle with respect to a leading target vehicle in the same lane as the host vehicle based, at least in part, on the target vehicle readings;

    predicting a lane cutout maneuver by the host vehicle or the leading target vehicle using the target vehicle readings, the lane cutout maneuver is a maneuver where the host vehicle or the leading target vehicle intentionally initiates or at least partially begins a lane change or lane departure from a current lane, the lane cutout maneuver prediction is at least partially based on the relative lateral position (xlat) of the host vehicle with respect to the leading target vehicle;

    determining whether the lane cutout maneuver is being performed by the host vehicle, by the leading target vehicle, or by both the host and the leading target vehicles, the lane cutout maneuver determination is at least partially based on a lateral distance between the host vehicle and a lane marking (xright, xleft) and the target vehicle readings; and

    controlling acceleration of the host vehicle with the automated driving system during the lane cutout maneuver, wherein the acceleration control is at least partially based on the lane cutout maneuver prediction and the lane cutout maneuver determination.
