Abstract
System, methods, and other embodiments described herein relate to detecting a lane change of a target vehicle ahead of an ego vehicle. In one approach, a method includes receiving communications from a target vehicle specifying state information about the target vehicle. The method includes determining a location of a first decision point at a first distance ahead of an ego vehicle and acquiring sensor data about the target vehicle. The method includes determining motion information about the target vehicle based on the sensor data. The motion information includes positions that the target vehicle occupied relative to the ego vehicle. The method includes storing the state information and motion information for a first amount of time, and determining whether the target vehicle has changed lanes based on the state information and the motion information that has been stored once the ego vehicle has reached the first decision position.
