Abstract
A vehicle control system that makes it possible to ensure the safety and enhance the productivity at the same time is provided. An unmanned dumpreceives positional information about a manned vehicleby using infrastructure-to-vehicle communicationand infrastructure-to-infrastructure communication. In a case where an inter-vehicle distance X between the unmanned dumpand the manned vehicleis equal to or shorter than a reference distance Y, the unmanned dumpdecides whether or not vehicle-to-vehicle communicationis established between the unmanned dumpand the manned vehicle. In a case where it is decided that the vehicle-to-vehicle communicationis established, the upper limit of the travel speed of the unmanned dumpis set to a first speed V, and in a case where it is decided that the vehicle-to-vehicle communicationis not established, the upper limit of the travel speed of the unmanned dumpis set to a second speed V
