Abstract: A vehicle travel control device controls travel of a vehicle toward a target stop position. Travel state information indicates a travel state of the vehicle and includes vehicle position information indicating positions the vehicle and each wheel. Difference-in-level position information indicates a position of a difference-in-level on a travel path. The vehicle travel control device determines whether the vehicle goes beyond the target stop position when a subject wheel of the vehicle passes the difference-in-level, based on the difference-in-level position information and the vehicle position information. When determining that the vehicle goes beyond the target stop position, the vehicle travel control device changes the target stop position so as to prevent the subject wheel from passing the difference-in-level, or generates a braking force to stop the vehicle before the subject wheel passes the difference-in-level.
