The notification control unit issues, to the occupant of the moving object, notification that the lane change control is to be started in response to the determination. The travel control unit starts the lane change control after a predetermined time elapses from when the notification is started. The predetermined time differs depending on a lane change direction of the moving object under the lane change control. ## Claims ### Claim 1 A control device configured to execute lane change control of changing a lane in which a moving object travels, the control device comprising: a hardware processor configured to recognize a surrounding situation of the moving object; determine, based on the surrounding situation recognized by the hardware processor, whether the lane change control is executable; execute the lane change control in response to the hardware processor determining that the lane change control is executable; and issue predetermined notification to an occupant of the moving object via a notification device mounted on the moving object, wherein the hardware processor issues, to the occupant of the moving object, notification that the lane change control is to be started in response to the hardware processor determining that the lane change control is executable, the hardware processor starts the lane change control in response to the hardware processor determining that the lane change control is executable again after a predetermined time elapses from when the hardware processor starts the notification that the lane change control is to be started, and the predetermined time differs depending on a lane change direction of the moving object under the lane change control. ### Claim 2 (depends on 1) The control device according to claim 1, wherein the predetermined time when the lane of the moving object is changed to a first direction under the lane change control is longer than the predetermined time when the lane of the moving object is changed to a second direction under the lane change control, the first direction being one direction in a left-right direction and the second direction being another direction in the left-right direction. ### Claim 3 (depends on 2) The control device according to claim 2, wherein visibility in the first direction when the occupant confirms surroundings of the moving object is worse than visibility in the second direction when the occupant confirms surroundings of the moving object. ### Claim 4 (depends on 3) The control device according to claim 3, wherein the first direction is a direction which is opposite to a side on which the occupant who is able to operate movement of the moving object gets in the left-right direction. ### Claim 5 (depends on 4) The control device according to claim 4, wherein the first direction is a direction which is opposite to a driver seat of the moving object in the left-right direction. ### Claim 6 (depends on 1) The control device according to claim 1, wherein the predetermined time changes based on at least one of the surrounding situation, a state of the occupant or a baggage in the moving object, or specifications of the moving object. ### Claim 7 (depends on 1) The control device according to claim 1, wherein the hardware processor starts the lane change control in response to determination that the occupant is in a state of being able to confirm surroundings of the moving object within the predetermined time. ### Claim 8 (depends on 1) The control device according to claim 1, wherein the predetermined time is a time from when the hardware processor starts the notification to when the lane change control is started, or a time from when the hardware processor starts the notification that the lane change control is to be started to when notification of executing the lane change control to an outside of the moving object is started. ### Claim 9 (depends on 1) The control device according to claim 1, wherein the predetermined notification issued by the hardware processor includes at least one of display using a display device mounted on the moving object and sound guidance using a sound output device mounted on the moving object.
