An intermediate car electric coupler control circuit for a subway vehicle includes a coupling state relay, a power supply circuit for a decoupling electromagnetic valve, a first power supply circuit for an electric coupler control relay, a second power supply circuit for an air path and electric coupler module control electromagnetic valve, and a third power supply circuit for a bus control contactor. A coupler coupling operation is performed exactly according to a sequence of a mechanical coupling, an air path conduction, an electric coupler extension, and a medium- and low-voltage bus closing, wherein contacts of electric couplers are prevented from being damaged. A coupler decoupling operation is performed exactly according to a sequence of a contact heavy-current removal, an electric coupler withdrawal, an air path disconnection and a mechanical decoupling, wherein the contacts are prevented from being damaged by a heavy current arcing and a discharge.
