Claim 0:
1. A powertrain control system of a vertical take-off and landing aerial vehicle, comprising:
a rotor driving motor directly connected to a rotor of the vertical take-off and landing aerial vehicle;
a battery connected to the rotor driving motor to supply power to the rotor driving motor motor;
a generator connected to the battery to charge and discharge the battery;
an engine connected to the generator to transmit power to the generator; and
a control device configured to control driving of the engine and the generator to charge the battery and to determine take-off and landing standby of the vertical take-off and landing aerial vehicle,
wherein the control device includes a main controller configured to:
control driving of the engine and the generator based on the information provided by a flight controller, a battery controller, the engine controller, and a generator controller; and
determine take-off approval or take-off standby of the vertical take-of and landing aerial vehicle or determine landing permit or landing standby of the vertical take-off and landing aerial vehicle; and

wherein the main controller includes:
an engine driving mode determination unit configured to determine an engine driving mode to be one of engine stop, engine passive run, engine idle, engine part load, and engine full load;
an engine driving amount calculation unit configured to calculate target torque of the engine and target revolutions per minute (RPM) of the engine for charging the battery;
a required engine torque determination unit configured to determine approval of injection of fuel to the engine, an engine torque command, approval of catalyst heating, and approval of engine self-diagnosis;
a required generator torque determination unit configured to determine a generator torque command; and
a take-off and landing standby request unit configured to determine the take-off and landing standby of the vertical take-off and landing aerial vehicle.
