Abstract: A vehicle control apparatus for controlling a vehicle based on peripheral information of the vehicle, the apparatus comprising: a control unit configured to control steering and acceleration/deceleration of the vehicle in a first state in which holding of a steering apparatus of the vehicle by a driver is required or a second state in which holding of the steering apparatus is not required, wherein the control unit transitions a state of the vehicle from the second state to the first state, if input of an intervention operation for acceleration/deceleration by the driver is detected in a case of executing course change of the vehicle, when the vehicle is traveling in the second state.

Abstract: A vehicle control device includes an external environment recognition unit that recognizes a situation of a surrounding periphery of a user's own vehicle, and a lane change control unit that executes an automatic lane change by controlling a travel speed and steering of the user's own vehicle based on a recognition result of the external environment recognition unit. The automatic lane change includes a first lane change (third mode) which is executed regardless of an intention of a driver, and a second lane change (first mode) which is executed in accordance with the intention of the driver. In the case that a request to make the second lane change is detected during execution of the first lane change, the lane change control unit switches the automatic lane change to be executed from the first lane change to the second lane change.
