COMMUNICATION SYSTEM BETWEEN SAFETY TRIANGLE AND BCM AND METHOD THEREOF

A communication system between a safety triangle and a BCM in a vehicle and a communication method thereof are provided to prevent an accident by informing a driver, when the safety triangle is fallen down due to strong wind or rain. A switch(13) turns on and off a safety triangle. When the switch is turned on, a transceiver(16) transmits a switch-on signal to a BCM(21) and wirelessly communicates with the BCM(Body Control Module). An MCU(Motor Control Unit)(19) enables the transceiver to communicate with the BCM, so that a distance between the BCM and the safety triangle is displayed. When the measured distance is maintained and varied within a predetermined reference radius for a predetermined interval, the MCU turns off the switch. A display unit(17) displays a distance between the safety triangle and a vehicle under the control of the MCU. The BCM measures the distance between the vehicle and the safety triangle. When the switch-on signal is received from the switch, the BCM flashes an emergency lamp of the vehicle.
