Abstract: A motor drive device includes a stator, a rotor, a first output shaft being provided in the rotor shaft and integrally rotating with a first drive gear, a second output shaft being provided in the first output shaft and integrally rotating with a second drive gear, a first one-way clutch being provided between an inner periphery of the rotor shaft and an outer periphery of the first output shaft, the first one-way clutch transmitting only a driving force that operates in a first direction, a second one-way clutch being provided between the inner periphery of the rotor shaft and an outer periphery of the second output shaft, the second one-way clutch transmitting only a driving force that operates in a second direction that is opposite to the first direction, and a decelerator.

Abstract: A hybrid vehicle drive device includes a first motor/generator, a second motor/generator, an input shaft to which an engine is rotatably connected, an output shaft which is rotatably connected to a drive wheel and the second motor/generator, a rotational member which is rotatably connected to the first motor/generator and the output shaft, and a first one-way clutch which connects the input shaft and the rotational member with each other when a rotation speed of the input shaft is faster than a rotation speed of the rotational member and disconnects the input shaft and the rotational member from each other when the rotation speed of the input shaft is slower than the rotation speed of the rotational member.

Abstract: A hybrid vehicle driving device includes: a first motor generator; a second motor generator; an input shaft; an output shaft; a rotating member rotatably linked to the output shaft; a connection member to which the first motor generator is connected; a connection mechanism which connects and disconnects the connection member and the rotating member; a one-way clutch connecting the input shaft and the connection member; a synchronization control portion synchronizing the rotational speed of the first motor generator with the rotational speed of the rotating member; a first engine control portion maintaining the rotational speed of an engine; a connection portion connecting the connection member and the rotating member to each other; and a second engine control portion controlling the engine such that the rotational speed of the input shaft is synchronized with the rotational speed of the connection member.
