Apparatus and method of complementing braking force of commercial vehicle

An apparatus comprising:

• a driving unit configured to drive an autonomous drone;
• a braking system connected with the driving unit and configured to complement a braking force, the braking system comprising:
• a compressor configured to discharge compressed air, wherein the driving unit is configured to apply an electric driving force to the compressor;
• an air tank configured to store the compressed air;
• and
• a braking complement unit connected with a discharge end of the air tank;
• a bypass valve disposed at a discharge end of the compressor;
• and
• a controller configured to determine a braking complement condition of a vehicle and to drive the braking system based on the braking complement condition,
• wherein the driving unit comprises:
• a fuel cell system configured to provide a driving force to the autonomous drone,
• a regenerative braking system configured to convert a braking force of the autonomous drone into electric energy, and
• a high-voltage battery configured to be charged from the fuel cell system or the regenerative braking system, and
• wherein the fuel cell system comprises:
• an exhaust system,
• a regulator disposed at a discharge end of the bypass valve,
• a cooler connected to a discharge end of the regulator, and
• a fuel cell stack connected between a discharge end of the cooler and the exhaust system.

An apparatus comprising:
