Provided are a communication module and a data segmentation transmission method using the same. The communication module includes a communication unit configured to support a wireless connection with a communication terminal, a control unit configured to segment data, which is received from the communication terminal supported in connection thereof, based on a first scale, and to transmit the segmented data to a driver information system (DIS), and a signal generation unit configured to, upon receiving an interrupt signal from the communication terminal, generate a connection signal to the DIS, wherein the control unit segments data, which is received from the communication terminal during an interval in which the connection signal is generated, based on a second scale, and transmits the segmented data to the DIS.
