Abstract: A control system for a moving body that can improve the accuracy of determining that autonomous movement cannot be continued, and realize a smoother transition to remote control. For this reason, there is provided a moving body control system which includes a moving body control device that is mounted on a moving body capable of autonomous movement, and a control device that controls the moving body from a remote place. The moving body control device includes an external information acquisition unit to acquire external information of the moving body, a movement information acquisition unit to acquire movement information of the moving body, a control unit to predict a future state of the moving body based on the external information and the movement information, and a moving body-side communication unit to communicate with the control device. The control device includes a control device-side communication unit to communicate with the moving body control device, a control simulator to predict a future state of the moving body based on the external information and the movement information received from the moving body control device, and an autonomous mobility determination unit that compares the future states predicted by the control unit and the control simulator and determines whether the autonomous movement of the moving body can be continued.

Abstract: In the present invention, it is possible to accurately predict, at an earlier timing, that a pedestrian will perform constant speed movement or a route change that is more complex than the constant speed movement. Provided is a travel control device that can accurately determine a change in the route of the pedestrian according to a change in the pedestrian's posture and, in particular, a change in the orientation of the body or a change in an inverted angle, and that can appropriately control the travel of the vehicle.
