VEHICLE CONTROL METHOD AND VEHICLE CONTROL DEVICE

A vehicle control device includes: a steering angle calculating unit (103) configured to calculate a target steering angle of a steering wheel of a subject vehicle such that the subject vehicle follows a travel trajectory for a lane change; a steering angle correcting unit (104) configured to correct the target steering angle based on a subject-lane slope representing a slope of a road surface in a width direction of a subject lane in which the subject vehicle is traveling and an adjacent-lane slope representing a slope of a road surface in a width direction of an adjacent lane being a lane change destination of the subject vehicle; and a steering control unit (105) configured to perform steering control such that a steering angle of the steering wheel follows the corrected target steering angle.
