Patent number: 7650973Abstract: A hydraulic power transmission device includes a toroid portion, a turbine hub, and a lock-up device. The toroid portion includes a pump impeller and a turbine runner. The turbine hub is engaged with an input shaft of a transmission and holds the turbine runner. The lock-up device is installed so that it engages and disengages freely and it mechanically transmits to the turbine hub rotation that is transmitted from a drive power source. The toroid portion and the lock-up device overlap in the axial direction.

Patent number: 7276007Abstract: A hybrid drive unit includes a three-element planetary gear coupled to two motors, and a reduction planetary gear which is drivingly connected to the three-element planetary gear and switches modes by controlling a clutch and a brake. A three-element direct drive mode is able to be achieved by providing another clutch which couples together any two elements of the reduction planetary gear, and locking up the reduction planetary gear. As a result, motor output is reduced compared with a four-element direct drive mode of related art during high-speed running, and energy recovery efficiency during regeneration can also be improved.Type: GrantFiled: March 25, 2005Date of Patent: October 2, 2007Assignee: Aisin AW Co., Ltd.Inventors: Shigeki Takami, Kozo Yamaguchi, Takeshi Inuzuka, Tomohiko Ito

Patent number: 7255186Abstract: An output of an internal combustion engine is transmitted to an output shaft by controlling a control motor to change a rotation speed output from the engine without speed steps via power distribution planetary gear. An output of a drive motor is input to the output shaft by changing the speed into two-step decelerated rotation by means of an automatic transmission. The transmission produces a desired torque by decelerating the speed by a large degree when a vehicle speed is low, and produces a desired number of revolutions by decelerating the speed by a small degree when the vehicle speed is high.Type: GrantFiled: July 30, 2003Date of Patent: August 14, 2007Assignees: Aisin AW Co., Ltd., Toyota Jidosha Kabushiki KaishaInventors: Satoru Wakuta, Kenji Omote, Takeshi Inuzuka, Kazuhisa Ozaki, Kazumasa Tsukamoto, Kozo Yamaguchi, Masatoshi Adachi, Kazutoshi Motoike, Masahiro Kojima

Patent number: 7089095Abstract: A control unit for a hybrid vehicle includes a take-off detection unit that detects a start of movement of the hybrid vehicle from a stopped state; and a torque control unit that limits a engine torque input to an automatic transmission from becoming excessive by generating negative torque using a regeneration operation of a motor on occasions when the start of running of the hybrid vehicle is detected by the take-off detection unit. Accordingly, it is possible to reliably inhibit problems, such as an occupant of the hybrid vehicle being caused to feel an unpleasant jolt due to torque transmitted to a driven wheel side increasing instantaneously as a result of change in an application state of a clutch during the start of movement.Type: GrantFiled: December 22, 2003Date of Patent: August 8, 2006Assignee: Aisin AW Co., LtdInventors: Shigeki Takami, Takeshi Inuzuka, Yasuhiko Kobayashi, Yoshitaka Murase, Yoichi Tajima, Takayuki Kubo, Takahiro Kido
