PROBLEM TO BE SOLVED: To suppress unfairness that a vehicle driver permitted to change lanes may feel.SOLUTION: A lane change assist system 1 comprises: a detection unit 20 detecting other vehicles around an own vehicle; a communication unit 22 holding communication between the own vehicle and each of the other vehicles around the own vehicle; and a determination unit 16a determining whether to transmit a lane change permission signal to the second other vehicle running on an adjacent lane adjacent to a running lane of the own vehicle if receiving a lane change request signal from the second other vehicle via the communication unit 22. If determining on transmitting a lane change permission signal to the first other vehicle before receiving the lane change request signal from the second other vehicle on the basis of a history of determination on transmitting the lane change transmission signal, and determining that the first other vehicle is not completed with a lane change in response to the lane change permission signal on the basis of a communication result of the communication unit 22 or a detection result of the detection unit 20, the determination unit 16a determines on not transmitting the lane change permission signal to the second other vehicle.

    【課題】車線変更を許可する車両の運転者に与える不公平感を抑制する。【解決手段】車線変更支援装置1は、自車両の周囲の他車両を検出する検出部20と、自車両と自車両の周囲の他車両との間で通信を行う通信部22と、通信部22を介して、走行車線に隣接する隣接車線を走行する第2の他車両から車線変更要求信号を受信した場合に、車線変更許可信号を第2の他車両に送信するか否かを決定する決定部16aと、を備える。決定部16aは、車線変更許可信号の送信決定履歴に基づいて、第2の他車両から車線変更要求信号を受信する前に第1の他車両に対する車線変更許可信号の送信を決定しており、且つ、通信部22による通信結果又は検出部16aによる検出結果に基づいて、第1の他車両が当該車線変更許可信号に応じた車線変更を完了していないと判定した場合には、第2の他車両に対して車線変更許可信号を送信しないと決定する。【選択図】図1
