PROBLEM TO BE SOLVED: To provide a movable body control system capable of predicting the occurrence of a communication failure due to the lowering of the receiving capability of a radio communication device.SOLUTION: A movable body comprises a driving position detection means for detecting the travel position thereof, and a travel controller for controlling travel actuation based on operation information received by a radio communication device and travel position information detected by the travel position detection means. An operation controller includes a receiving capability evaluation means for comparing reception strength corresponding to the travel position of the movable body obtained based on the travel position information Pp that the movable body sends using the radio communication unit and on reception strength information Pr indicating the reception strength of a radio signal that the radio communication device receives from a communication relay device and reference reception strengths Ls1, Ls2 for the travel position, so as to determine whether or not the radio communication device is in a lowered state of reception capability in which its reception capability is lowered. |
