Abstract
A powertrain control system is provided for a vertical take-off and landing aerial vehicle for urban air mobility. A powertrain of the vertical take-off and landing aerial vehicle is a hybrid type powertrain, in which the output shaft of a rotor driving motor is directly connected to a rotor, a battery is connected to the rotor driving motor to supply power thereto, and an engine and a generator are connected to a battery to charge and discharge the battery. The driving of the engine and the generator is controlled based on required power of the motor and the SOC of the battery in each flight step of the vertical take-off and landing aerial vehicle, and the SOC of the battery is constantly maintained at a predetermined level or higher.
Claims11
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.
