The controller is further configured for causing the generator/motor to convert rotary motion of the auxiliary wheel into a different form of energy and to cause the energy so converted to be stored in the energy storage device as a vehicle decelerates. Methods are also provided.Type: ApplicationFiled: November 20, 2007Publication date: May 21, 2009Inventor: Scott Daniel Batdorf

Publication number: 20090125172Abstract: In an OFF condition of an ECO switch, a stop decision reference value Wstop is set to a value W1 (step S420). In an ON condition of the ECO switch, the stop decision reference value Wstop is set to a value W2 (step S430). When an output limit Wout of a battery set according to a battery temperature and a state of charge of the battery is not less than the set stop decision reference value Wstop, the engine is permitted to stop (step S450). When the output limit Wout is less than the set stop decision reference value Wstop, the engine is prohibited from stopping (step S460). The value W1 is specified as a value of electric power required for a smooth restart of the engine after its stop during a drive of the vehicle. The value W2 is specified to be close to a value of minimum electric power required for a restart of the engine after its stop during a drive of the vehicle and is set to be smaller than the value W1.Type: ApplicationFiled: November 6, 2008Publication date: May 14, 2009Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Tatsuyuki MATSUBARA

Patent number: 7510036Abstract: A cover accommodates a power converter receiving high voltage. A connector assembling portion to which a connector of an external power line is assembled is arranged external to the cover and secured by a securing member to a vehicle's main body. A support member is arranged at a lower surface of the cover and connector assembling portion, rather than that portion of casing connecting the connector assembling portion and the power converter's main body, between the cover and the connector assembling portion and thus binds them together.Type: GrantFiled: March 8, 2006Date of Patent: March 31, 2009Assignee: Toyota Jidosha Kabushiki KaishaInventors: Takaji Kikuchi, Takeshi Menjo

Patent number: 7509802Abstract: An apparatus for supporting an electric power source in a transmission includes a transmission housing, and an electric machine including a rotor and a stator secured to the housing. A first member is secured to the rotor, extends radially toward an axis of rotation, and is formed with a first pilot surface. A second member, secured to the rotor and the housing, extends from the housing toward the axis and is formed with a second pilot surface that is aligned axially with the first pilot surface. An anti-friction bearing, located at an axial rearward side or axially frontward side of a torque converter, is engaged with the first pilot surface and the second pilot surface. A second balanced bearing is located either in the driving engine or the driven transmission.Type: GrantFiled: September 26, 2006Date of Patent: March 31, 2009Assignee: Ford Global Technologies, LLCInventors: Matthew D. Hammond, Michael T. Berhan, Jeffrey E. Maurer, Steve G. Thomas, Julie A. Sunstein

Patent number: 7503865Abstract: An infinitely-variable power-branching transmission with two operating modes. The transmission components are distributed between two power paths connecting in parallel a heat engine to vehicle wheels, including at least first planetary trains, two electrical machines, and a reduction stage. A third planetary train co-operates with control members to establish the two transmission operating modes and to switch there between.Type: GrantFiled: September 10, 2004Date of Patent: March 17, 2009Assignee: Renault S.A.S.Inventor: Yves Pichon

Publication number: 20080125926Abstract: A plurality of electric devices constituting an electric vehicle control device (6) are arranged as a unitary block of a frame and a case. A fixed unit (6a) is arranged at several positions on a horizontal plane between the upper end and the lower end of the electric control device mounted on an electric vehicle (1). The electric devices are arranged so that the center of gravity of the electric vehicle control device (6) is substantially on the horizontal plane of the fixed unit (6a). Since it is possible to suppress vibration during travel of the electric vehicle, it is possible to reduce the strength of the electric vehicle and reduce its weight.Type: ApplicationFiled: October 27, 2005Publication date: May 29, 2008Applicant: Mitsubishi Electric CorporationInventors: Yasuaki Mamoto, Hidetoshi Sumita
