Abstract:
1. A method of detecting disconnection of an input fuse connected to an input terminal of a low-voltage DC-DC converter (LDC), the method comprising: comparing, by a controller, an input voltage value through the input terminal of the LDC with a setting voltage in an ignition on-state and an on-state of a main relay for connection of a high-voltage battery; verifying, by the controller, whether the main relay is in the on-state; verifying, by the controller, whether the voltage of an input capacitor in an inverter is in a normal voltage range; and diagnosing, by the controller, that a disconnection of the input fuse connected to the input terminal of the LDC has occurred in a low-voltage state in which the input voltage value is no more than the setting voltage, the main relay is in the on-state, and the voltage of the input capacitor in the inverter is in the normal voltage range, wherein the input fuse is connected to the input terminal of the LDC to which a voltage of the high-voltage battery is input.
