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.

    Abstract: A travel controller executes travel control of a vehicle including collision avoidance control, based on environmental information including control information received from a control device and environmental data outputted from an environmental sensor mounted on the vehicle, each indicating conditions around the vehicle. The travel controller regulates the speed of the vehicle when a delay time in receiving the control information exceeds a delay threshold. The travel controller sets the delay threshold to a first threshold when an estimated avoidance difficulty from the environmental information is less than a difficulty threshold; and sets the delay threshold to a second threshold less than the first threshold when the estimated avoidance difficulty is greater than the difficulty threshold.
