Abstract: A virtual driving system for efficiently testing an interlock operation is provided. The virtual driving system comprises an optical cable installed on a rail; a transport cart for driving in place on the rail and communicating with the optical cable; a first collision avoidance control unit set to correspond to a first virtual path of the transport cart; a second collision avoidance control unit set to correspond to a second virtual path different from the first virtual path of the transport cart; a signal line distribution unit for selectively connecting any one of the first collision avoidance control unit and the second collision avoidance control unit to the optical cable; and a simulator for controlling the first collision avoidance control unit, the second collision avoidance control unit, and the signal line distribution unit according to an operation scenario of the transport cart.

Abstract: A transport vehicle management method includes self-testing a transport vehicle to determine whether there is an abnormality in the transport vehicle, checking whether the transport vehicle is capable of self-correcting the abnormality when the abnormality is detected in the transport vehicle, and self-correcting the abnormality when the transport vehicle is capable of self-correcting the abnormality.
