Abstract: A driver assistance apparatus includes an environment information acquisition unit and an overtaking control processor. The environment information acquisition unit acquires a traveling environment information of an own vehicle. The overtaking control processor executes overtaking control based on relative vehicle speeds and positional relations of the own vehicle with a preceding vehicle and an adjacent-lane vehicle that are detected based on the traveling environment information. The overtaking control processor includes an overtaking schedule generator and an overtaking control execution unit. The overtaking control processor generates, in advance before the overtaking control, an overtaking schedule regarding first automatic lane change control adapted to move the own vehicle to an adjacent lane and second automatic lane change control adapted to cause the own vehicle to overtake the preceding vehicle and return to an original lane.
