Abstract
Methods and systems for detecting lane changes using vehicle path data. In some implementations, one or more environmental sensors, such as RADAR modules, may be used to generate a first data set associated with a trajectory of a host vehicle. The first data set may be representative of a curve on a graph. Points of inflection may be sought in the curve. An identification of a point of inflection in the curve may then be used to confirm a lane change of the host vehicle.
