Abstract: When determining that, with an adjacent preceding vehicle selected as a tracking-control target, (i) an operated acceleration request for an own vehicle has been inputted to a vehicle control apparatus and (ii) the adjacent preceding vehicle is likely to be changed as an own-lane preceding vehicle, the vehicle control apparatus performs tracking control of the own vehicle with respect to the adjacent preceding vehicle. When determining that, with the adjacent preceding vehicle selected as the tracking-control target, (i) the operated acceleration request for the own vehicle has been inputted to the vehicle control apparatus and (ii) the adjacent preceding vehicle is unlikely to be changed as an own-lane preceding vehicle, the vehicle control apparatus terminates the tracking control of the own vehicle.
