Provided is a vehicle management system with which the safety of a guided vehicle can be ensured while suppressing a decrease in productivity by improving the setting of an entry-prohibited region of an unmanned vehicle when an abnormal state of position information on the guided vehicle is detected. This vehicle management system is configured such that an unmanned vehicle, a guided vehicle, a guiding vehicle, and a management station for managing and controlling the unmanned vehicle on the basis of position information on the guiding vehicle and position information on the guided vehicle are able to communicate with each other. When an abnormal state of the position information on the guided vehicle is detected, a management control device of the management station calculates an inter-vehicle distance between the guiding vehicle and the guided vehicle before the detection of the abnormal state, and sets an entry-prohibited region of the unmanned vehicle on the basis of current position information on the guiding vehicle and the inter-vehicle distance. An output device of the guiding vehicle outputs a warning for prompting maintenance of the inter-vehicle distance when the abnormal state of the position information on the guided vehicle is detected.
