Abstract: A method and a device for controlling an OHT vehicle are proposed. The method and device presents a solution in which it is possible to minimize a repetition of start and stop of a vehicle, due to congestion on a track, by providing a buffer distance or a buffer waiting time, when the control target vehicle starts due to moving out of range of a proximity distance to a preceding vehicle, after stopping according to reaching of the proximity distance to the preceding vehicle, during driving the OHT control target vehicle.
