PROBLEM TO BE SOLVED: To provide a lane change assist system capable of more suitably performing the assistance regarding a lane change, particularly in a vicinity of a fork road.SOLUTION: A lane change assist system 10 obtains branch point information that is information regarding branch points along the travel route to the own vehicle's destination, then determines the driver's will to a lane change as well as the direction of the lane change in the driver's intention. Also, in response to the direction indicator, an assistance command is outputted to a steering system 50 to assist the steering. When the driver's will to change the lane is determined, and if it is presumed, on the basis of the branch point information, that the own vehicle is going to enter a fork road in a different direction from the direction of the lane change in the driver's intension, the difficulty level to enter the fork road caused by the lane change is determined. If the determined difficulty level is a level at which an entrance to the fork road becomes difficult, the steering assistance is restrained.
【課題】特に分岐路近辺での車線変更に関する支援をより適切に行うことの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は、自車両の目的地までの走行経路における分岐点に関する情報である分岐点情報を取得し、運転者の車線変更の意思を判断するとともに、運転者の意図する車線の変更方向を判断する。また方向指示に応じてステアリングシステム50に支援指令を出力して操舵支援を行う。そして運転者の車線変更の意思が判断され、且つ分岐点情報に基づき、運転者の意図する車線の変更方向と異なる方向の分岐路に自車両が進入すると推定されるとき、車線変更による当該分岐路への進入の難易度を判定し、当該判定された難易度が、分岐路への進入が困難となるレベルであるときには、操舵支援を抑制する。【選択図】図1
