Vehicle control device

A vehicle control device that automatically controls a speed of an own vehicle, the vehicle control device comprising:

• a preceding vehicle relationship value detection unit that detects a preceding vehicle relationship value that is a relative relationship value in an advancing direction between a preceding vehicle traveling immediately in front of the own vehicle in an own vehicle lane in which the own vehicle is traveling and the own vehicle;
• an acceleration/deceleration control unit that controls acceleration/deceleration of the own vehicle on the basis of the preceding vehicle relationship value;
• an adjacent vehicle relationship value detection unit that detects an adjacent vehicle relationship value that is a relative relationship value in the advancing direction between an adjacent vehicle traveling in an adjacent lane adjacent to the own vehicle lane in the same direction as the own vehicle and the own vehicle;
• and
• a lane change detection unit that detects cut-in of the adjacent vehicle to the own vehicle lane,
• wherein the lane change detection unit determines a possibility of cut-in of the adjacent vehicle immediately in front of the own vehicle on the basis of the adjacent vehicle relationship value in the advancing direction, and
• the acceleration/deceleration control unit corrects acceleration/deceleration of the own vehicle on the basis of the possibility of the cut-in that is determined on the basis of the adjacent vehicle relationship value in the advancing direction.
