PROBLEM TO BE SOLVED: To provide a lane change support device capable of notifying a user of existence of another vehicle on the diagonally rear side at an earlier timing.SOLUTION: A lane change support device 10 is configured so that, a vehicle information acquisition part 12 acquires vehicle information including information on vehicle speed of the vehicle equipped with the device. A diagonally-rear-side information acquisition part 13 acquires information on whether or not there is another vehicle on the diagonally rear side of the vehicle equipped with the device, and diagonally-rear-side information of a relative position and relative speed of the other vehicle existing on the diagonally rear side of the vehicle equipped with the device, to the vehicle. A current lane change cautionary degree determination part 14 determines a current lane change cautionary degree from the vehicle information and the diagonally-rear-side information. A future lane change cautionary degree estimation part 15 estimates a future lane change cautionary degree from the vehicle information and the diagonally-rear-side information. A notification processing part 16 notifies a driver of the current lane change cautionary degree and the future lane change cautionary degree using a notification device 20.SELECTED DRAWING: Figure 1
【課題】より早いタイミングで後側方の他車両の存在を通知できる車線変更支援装置を提供する。【解決手段】車線変更支援装置10において、自車両情報取得部12は、自車両の車速の情報を含む自車両情報を取得する。後側方情報取得部13は、自車両の後側方に他車両が存在するか否かの情報、ならびに、自車両の後側方に存在する他車両の自車両に対する相対位置および相対速度の情報を含む後側方情報を取得する。現在車線変更要注意度判定部14は、自車両情報および後側方情報から、現在の車線変更要注意度を判定する。将来車線変更要注意度推定部15は、自車両情報および後側方情報から、将来の車線変更要注意度を推定する。通知処理部16は、通知装置20を用いて、現在の車線変更要注意度および将来の車線変更要注意度を運転者に通知する。【選択図】図1
