摘要： A propulsion assembly includes a first torque source coupled with a first shaft and a second torque source coupled with a second shaft. A coupler selectively couples the first and second torque sources. When the first and second torque sources are coupled via the coupler, in response to a command to decouple the first torque source, an unloading operation is performed to decrease the torque output provided by the first torque source to a threshold, and when reached, the first shaft is decoupled from the coupler. When the first torque source is coupled with the coupler but the second torque source is not, in response to a command to couple the second torque source, a speed matching operation is performed to increase the speed of the second shaft to match a speed of the first shaft, and when the speeds are matched, the second shaft is coupled to the coupler.

摘要： 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.
