PURPOSE: A device for controlling power supply in the case of engine stop of a vehicle is provided to prevent CAN communication errors by cutting off battery power supplied to an engine ECU and an ABS ECU even if engine starting is stopped by turning off engine stop switches. CONSTITUTION: Engine stop switches(240) are electrically connected between an ignition switch(230) and an engine ECU(Electronic Control Unit)(210), and between the ignition switch and an ABS(Antilock Brake System), ECU(220). If the ignition switch is turned on and the engine stop switches are turned on, the engine ECU and the ABS ECU receive battery power for executing CAN(Control Area Network) communication. If the ignition switch is turned on and the engine stop switches become off, the battery power supplied to the engine ECU and the ABS ECU is cut off. If the ignition switch is turned off, the battery power supplied to the engine ECU and the ABS ECU is cut off.
