Abstract
An object of the present invention is to provide a steering control device and a steering control method that can reduce a driving burden imposed on a driver during low velocity driving. The present invention is provided with an arithmetic logic unit that changes a steering angle of a wheelby driving a wheel steering actuatorbased on a manipulated variable of a steering, and calculates a controlled variable of the wheel steering actuator. In turning the steering, the arithmetic logic unit controls the wheel steering actuatorbased on a first gain at which a ratio of an actual steering angle of the wheelchanges with respect to a steering angle δ, and in returning the steering, the arithmetic logic unit controls the wheel steering actuatorbased on a second gain that differs from the first gain.
