1. A method for performing shift characterization, comprising:
determining whether an ego vehicle is decelerating based on one or more vehicle control and motion status measurements;
monitoring, using a sensor unit, driver input and one or more driving situations for the ego vehicle;
when the ego vehicle is decelerating, determining, using a processor and based on the driver input and the one or more driving situations for the ego vehicle from the sensor unit, whether the ego vehicle is entering into a passing maneuver; and
when it is determined that the ego vehicle is entering into the passing maneuver, performing a shift control modification of the ego vehicle,
wherein the determining whether the ego vehicle is entering into the passing maneuver comprises:
determining whether a preceding vehicle is present,
when the preceding vehicle is not present, determining that the ego vehicle is not entering into the passing maneuver;
when the preceding vehicle is present, determining whether a right or left turn signal has an on value; and
when the right or left turn signal does not have an on value:
determining whether an input steering angle turn rate of the ego vehicle is greater than or equal to a steering angle turn rate for a time duration greater than or equal to a time duration for a steering rate check, wherein, when the input steering angle turn rate of the ego vehicle is not greater than or equal to a steering angle turn rate for a time duration greater than or equal to a time duration for a steering rate check, determining that the ego vehicle is not entering into the passing maneuver; or
determining whether a camera of the sensor unit detects that the ego vehicle is changing lanes, wherein, when the camera of the sensor unit does not detect that the ego vehicle is changing lanes, determining that the ego vehicle is not entering into the passing maneuver.
