To perform speed control of an own vehicle when other vehicle makes a lane change.SOLUTION: A control device 100 comprises: an acquisition part 111 which acquires vehicle information concerning an own vehicle 10, M0 and other vehicles M1, M2, M3; a first calculation part 112 which calculates a first target acceleration a1 for so travelling as to follow a first vehicle which is a current preceding vehicle; a second calculation part 114 which calculates target accelerations a2, a3 in order that the own vehicle so travels as to follow other vehicles M2, M3; a determination part 113 which determines whether there is possibility that the preceding vehicle is changed from the first vehicle M1 to other vehicles M2, M3 or not in the state that the own vehicle travels on a first runway; a selection part which selects a smaller acceleration from the first target acceleration and target accelerations for so travelling as to follow other vehicles as a target acceleration of the own vehicle until the preceding vehicle is changed; and a speed control part 116 which controls a speed of the own vehicle by use of the selected target acceleration of the own vehicle.SELECTED DRAWING: Figure 1 【課題】他の車両がレーンチェンジをする場合において、自車両の速度制御を行う。【解決手段】制御装置１００は、自車両１０、Ｍ０及び他車両Ｍ１、Ｍ２、Ｍ３の車両情報を取得する取得部１１１と、現在の先行車両である第１車両に追従走行するための第１目標加速度ａ１を算出する第１算出部１１２と、自車両が他車両Ｍ２、Ｍ３に追従走行するための目標加速度ａ２，ａ３を算出する第２算出部１１４と、自車両が第１走路を走行している状態において、先行車両が第１車両Ｍ１から他車両Ｍ２、Ｍ３に切り替わる可能性があるかを判定する判定部１１３と、先行車両が切り替わるまでの自車両の目標加速度として、第１目標加速度と、他車両に追従走行するための目標加速度とのうち、小さい方の目標加速度を選択する選択部と、選択された自車両の目標加速度を用いて自車両の速度を制御する速度制御部１１６と、を備える。【選択図】図１
