At this time, the server 110 constructs a vehicle-specific database including the vehicle, and obtains an electronic control unit (ECU) number of the vehicle received from the control device 120 or a vehicle body control corresponding to the vehicle- Module (Body Control Module: BCM) setting information to the control device. At this time, the setting information is set according to the time interval at which the power supply of the vehicle body control module (BCM) is cut off in the database for each vehicle type, and the set time may vary depending on the type of vehicle.

The external device means the control device 120, and the control device 120 can control the body control module (BCM) of the vehicle through the OBD connection terminal of the vehicle.

The control device 120 may read the vehicle characteristic information via the OBD connection terminal of the vehicle or may transmit the vehicle information to the server 110 via a general smart device as well as a direct connection with the server 110. [ Vehicle characteristics information may vary depending on the type of vehicle and means information that can control the vehicle door opening / closing, a lid opening / closing, a turn signal light, an emergency light, a beep sound, a rearview mirror, a rearview mirror polling, a headlight, a rain sensor air conditioner, do.

The control device 120 and the smart device may communicate with each other via Bluetooth, Wi-Fi, 3G communication, And can transmit and receive data in real time by being connected through communication.

When the vehicle body control module (BCM) is continuously activated through the control device 120, the control device 120 may also detect the voltage of the vehicle itself because it may affect the battery of the vehicle.

Accordingly, the control device 120 compares the detected vehicle voltage with a preset first reference voltage, and when the voltage of the vehicle is equal to or higher than the first reference voltage, the communication state between the vehicle body control module BCM and the control device 120 And can stop the communication between the vehicle body control module BCM and the control device 120 when the voltage of the vehicle is less than the first reference voltage and equal to or higher than the second reference voltage set in advance.

At this time, if the voltage of the vehicle is less than a preset second reference voltage, the controller 120 may be turned off.

The server 110 may accumulate an electronic control unit (ECU) number or vehicle characteristic information of the vehicle transmitted from the control device in a database.

In another embodiment of the present invention, the smart device transmits vehicle characteristic information received from the control device 120 to the server 110 while acting as an intermediary, and transmits a vehicle body control module (Body Control Module: BCM) setting information.

OBD also means a legally defined subdiagnosis / surveillance system integrated in an institutional control system. The OBD monitors all systems associated with exhaust and evaporative gases throughout the entire operating range. If the monitoring systems fail, the fault history is stored in the ECU and can be queried via the standardized interface - 16-pin diagnostic connector. In addition, a malfunction indicator message (MIL: Malfunction Indicator Lamp) or message is sent to the driver.

A method of controlling a vehicle body control module using an external device (control device) may detect a voltage of the vehicle, and when the voltage of the vehicle is equal to or greater than a predetermined first reference voltage using the detected voltage, (BCM) and the control device, and controls the communication between the body control module (BCM) and the control device to be interrupted when the first reference voltage is lower than the first reference voltage and is equal to or higher than a preset second reference voltage can do.

When the communication state between the engine control module (ECM) and the OBD is interrupted, the control signal is not received from the engine control module (ECM) for a predetermined time in the OBD, and the power of the vehicle body control module (BCM) is cut off.

The controller 120 checks the communication state between the engine control module ECM and the OBD so that the engine control module ECM is turned on for a preset time (for example, 30 seconds) And interrupts communication with the engine control module (ECM) when communication is not established for a preset time (for example, 30 seconds).

At this time, the vehicle body control module BCM maintains the existing set value and also maintains the set value of the controller 120. [

If the voltage of the vehicle is less than the first reference voltage, it is determined whether the voltage of the vehicle is equal to or higher than the second reference voltage (S330). If the voltage of the vehicle is equal to or higher than the second reference voltage, communication with the vehicle body control module (S340). Thereafter, when the vehicle is started or the voltage of the vehicle rises above the first reference voltage, it can operate with the set value of "1.1.15. Set BCM Init Type. (Sub ID $ 0D)".

Further, when the voltage of the vehicle is less than the second reference voltage, when the detected voltage of the vehicle is maintained for a predetermined time (for example, one minute) or is lower than the second reference voltage, Mode (S350) so that the power of the control device 120 can be shut off or changed to the standby mode. Thereafter, when detecting the start of the vehicle, the control device 120 can be activated by operating with a set value of " 1.1.15 Set BCM Init Type. (Sub ID $ 0D) ".
