MOVING BODY CONTROL SYSTEM AND MOVING BODY CONTROL METHOD

A moving body control system executes a localization process that estimates a position of a moving body based on sensor-detected information and feature object map information indicating a position of a feature object. The moving body control system executes driving assist control based on the estimated position of the moving body. A first range includes the estimated position of the moving body and becomes larger as reliability of the localization process becomes lower. A first future range is at least a part of an expected passing range of the first range. When an obstacle is present in the first range or the first future range, the moving body control system makes the moving body decelerate or stop. When no obstacle is present in the first range or the first future range, the moving body control system continues the driving assist control.
