VEHICLE CONTROL DEVICE

A steering control unit performs lane keeping control to cause a steering system to operate to reduce a distance between a width-direction center position of a lane and a position where the vehicle is traveling in the lane on the basis of a recognized state of the lane obtained by a lane recognizing unit. A road condition determining unit determines whether the road on which the vehicle is traveling is a straight road. A lane keeping responsivity setting unit sets, when it is determined by the road condition determining unit that the road on which the vehicle is traveling is a straight road, responsivity of the lane keeping control to the distance to be lower than responsivity set when it is determined that the road on which the vehicle is traveling is not a straight road.
