CONTROL DEVICE

A control device for performing a travel control of a vehicle includes: a lane change intention detection unit configured to detect an intention of a driver to change a lane based on a predetermined operation on an operation device by the driver; and a travel control unit configured to determine whether a lane change of the vehicle is possible based on a surrounding situation, and to control the lane change based on a detection result of the lane change intention detection unit and a determination result of whether the lane change is possible. The travel control unit is configured to determine a start timing of a lateral movement in the lane change based on an operation on the operation device when the lane change is possible after the intention of the driver to change the lane is detected.
