Patent number: 8914179Abstract: During an inertial energy storage operation, electric power conversion at an inverter is controlled such that a direct current electric power from an electric power storage device is converted into an alternating current by the inverter so as to be supplied to stator windings, such that torque in the direction of engine rotation is applied to an output side rotor from a stator to rotatively drive the output side rotor in a state where power transmission from the output side rotor to a drive axle is stopped. During a cranking operation after the inertial energy storage operation, the electric power conversion at an inverter is controlled to permit application of the alternating current to rotor windings, such that a torque in the direction of engine rotation is applied to an input side rotor from the output side rotor, thereby rotatively driving an input side rotor to crank the engine.Type: GrantFiled: March 27, 2012Date of Patent: December 16, 2014Assignees: Kabushiki Kaisha Toyota Chuo Kenkyusho, Toyota Jidosha Kabushiki Kaisha, Aisin Seiki Kabushiki KaishaInventors: Eiji Tsuchiya, Takao Watanabe, Shu Asami, Tatsuya Miyano, Akira Murakami, Hiroyuki Ogawa, Tomoyuki Toyama

Publication number: 20140315675Abstract: When a first drive shaft and a second drive shaft rotate at equal rotational speeds, a first rotor and a second rotor rotate at equal rotational speeds. On the other hand, a rotational difference is generated between the first drive shaft and the second shaft by generating a torque between the first rotor and the second rotor and consequently, a rotational difference between the first rotor and the second rotor, so that a torque distribution between the first drive shaft and the second drive shaft is adjusted according to the torque generated between the first rotor and the second rotor. With this process, the torque distribution between the first drive shaft and the second drive shaft is adjusted without complicating the structure, and a loss when the first drive shaft and the second drive shaft rotate at equal rotational speeds is reduced.Type: ApplicationFiled: April 9, 2014Publication date: October 23, 2014Applicant: KABUSHIKI KAISHA TOYOTA CHUO KENKYUSHOInventor: Takao WATANABE

Publication number: 20140232228Abstract: A rotational difference is generated between a first and a second rotor and a third rotor, which causes an induced current to flow in a first rotor winding. This causes a torque to act between the first rotor and the third rotor. The rotary magnetic field generated by the induced current flowing through a second rotor winding interacts with a second stator, which in turn generates an induced electromotive force in a second stator winding. The induced electromotive force is applied via a phase adjustment circuit to a first stator winding, which generates a rotary magnetic field and causes a torque to act between the first stator and the third rotor. The rotary magnetic field generated by the second rotor winding and the induced current flowing in the second stator winding causes a torque to act between the second stator and the second rotor.Type: ApplicationFiled: April 29, 2014Publication date: August 21, 2014Applicants: KABUSHIKI KAISHA TOYOTA CHUO KENKYUSHO, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takao WATANABE, Eiji TSUCHIYA, Hiroyuki NISHIZAWA, Takeshi KITAHATA
