Integration Interworking Control Method and System

The purpose of the present invention is to provide an integrated interworking control method and a system using the same, which can share the operation state information of an idle stop and go (ISG) system and a smart cruise control (SCC) system of a vehicle and can control each system by interworking with the ISG system and the SCC system using the shared operation state information in order to solve the above problems. According to a preferred embodiment of the present invention, an integrated interworking control method controls a vehicle by interworking with an ISG system and an SCC system. The method comprises: an ISG control step of receiving the operation information of the SCC system and controlling the ISG system, based on the received operation information of the SCC system; and an SCC control step of receiving the operation information of the ISG system and controlling the SCC system, based on the received operation information of the ISG system.
