Vehicle Management System

Provided is a vehicle management system capable of securing safety of an escorted vehicle while suppressing a decrease in productivity by improving setting of an entry prohibited area of an unmanned vehicle at the time when an abnormal state of position information on the escorted vehicle has been detected. The vehicle management system is configured such that an unmanned vehicle, an escorted vehicle, an escorting vehicle, and a control station that controls the unmanned vehicle on the basis of position information on the escorting vehicle and position information on the escorted vehicle are capable of communicating with each other. A controller of the control station computes, when an abnormal state of the position information on the escorted vehicle has been detected, an inter-vehicle distance between the escorting vehicle and the escorted vehicle before the detection of the abnormal state, to thereby set an entry prohibited area of the unmanned vehicle on the basis of the current position information on the escorting vehicle and the inter-vehicle distance. An output device of the escorting vehicle outputs an alarm that prompts maintenance of the inter-vehicle distance when the abnormal state of the position information on the escorted vehicle has been detected.
