In a hybrid vehicle, in order to stop an engine while a clutch is kept engaged and to transmit power from a motor to a drive shaft by changing a change speed state of a transmission when the power from a second motor is being transmitted to the drive shaft by the transmission, for example, a rotation speed of the first motor is adjusted so that the first motor can be connected to the drive shaft with the clutch disengaged while torque commands for both motors are set so that the power based on torque demand is outputted to the drive shaft, the power is transferred from the second motor to the first motor while both motors are connected to the drive shaft by the transmission, and the connection between the second motor and the drive shaft by the transmission is disconnected.
A power output apparatus for outputting power to a drive shaft, the power output apparatus comprising:
A hybrid vehicle including a drive wheel driven by power from a drive shaft, the hybrid vehicle comprising:
A control method of a power output apparatus including a drive shaft, an internal combustion engine, first and second motors respectively capable of inputting and outputting power, an accumulator unit capable of exchanging electric power with each of the first and second motors, a power distribution and integration mechanism having a first element connected to a rotating shaft of the first motor, a second element connected to a rotating shaft of the second motor, and a third element connected to an engine shaft of the internal combustion engine and constituted so that these three elements are capable of mutually differential rotation, a connecting/disconnecting unit capable of a driving source-element connection and a disconnection of the driving source-element connection, the driving source-element connection being any one of a connection between the first motor and the first element, a connection between the second motor and the second element, and connection between the internal combustion engine and the third element, a transmission mechanism capable of selectively connecting either one or both of the rotating shaft of the first motor and the rotating shaft of the second motor to the drive shaft and of transmitting the power from the first motor and the power from the second motor to the drive shaft at respective predetermined speed ratios, the control method comprising steps of:
