Abstract
Provided are a vehicle steering device and the like, which are capable of converging a lateral displacement at a forward gazing-point distance to a target travel line with simple control. A target travel line for a vehicle to travel by following a travel path recognized from an image taken by a camera or the like is set. A lateral speed, which is a change amount of the lateral displacement that is a difference between a position of the target travel line at the forward gazing-point distance and a position of the vehicle, is controlled so that the lateral displacement is reduced. A target steering angle is calculated based on the lateral speed, and a steering angle of the vehicle is controlled based on the calculated target steering angle.
