Abstract: A method of controlling lane change of an autonomous vehicle is provided. The method includes determining a type of a command for lane change by an autonomous driving logic of an electronic control unit (ECU) in response to the command for lane change being generated. When the command for lane change is not a specific command for lane change, attributes of each of at least one region included in a change target region is determined using information regarding the change target region. The attributes of each of the at least one region are corrected using information regarding a lane in which the autonomous vehicle is driven and a lane change region is determined from the at least one region based on the corrected attributes of each of the at least one region.

In particular, objects present in a detection area of a front impact sensor provided on a vehicle are detected. A movement path vector of a first moving object that is moving in a direction identical to that of the vehicle, among the objects present in the detection area, is generated. When the movement path vector of the first moving object falls within an error range of a movement vector of the vehicle, the first moving object is designated as belonging to a group of laser warning target candidates, and thereafter an emission angle of a laser beam is generated. The laser beam is emitted through a laser light based on the emission angle of the laser beam.
