Patent number: 8914173Abstract: A method and system for conditioning an energy storage system (ESS) for a vehicle, like a high-voltage battery or a fuel cell used for vehicle propulsion. It may be detrimental for a high-voltage battery in a parked vehicle to be exposed to extreme temperatures for an extended period of time. Thus, the method and system may be used to condition such a battery—for example, by heating it up if it is too cold or by cooling it down if it is too hot—so that the performance, durability, lifespan and/or other aspects of the battery are improved. In an exemplary embodiment, the method predicts if the battery will need conditioning the next time the vehicle is parked and, if such conditioning is needed, then the method predicts if the battery has sufficient charge to perform this conditioning. If the charge appears insufficient, then the method operates an energy generator that provides additional charge to the battery in anticipation of the needed conditioning.Type: GrantFiled: December 21, 2010Date of Patent: December 16, 2014Assignee: GM Global Technology Operations LLCInventors: William A.

Publication number: 20140257618Abstract: A hybrid vehicle includes a clutch on a power transmission path between a motor generator and a driving wheel. If the vehicle moves backward when the vehicle starts forward acceleration from standstill on an ascending slope, the charging level of the battery that is attributable to power generation by the motor generator due to the backward travel is compared with a current maximum charging power of the battery.

The first valve is opened to increase the level of fluid in the main sump to at least a predetermined height so that transmission rotating components contact the fluid and generate splash lubrication. When the transmission is transmitting torque and the fluid is above the predetermined temperature, the level of fluid in the main sump is maintained below a predetermined height with closed first valve, such that the rotating components do not contact the fluid inside the main sump. A fluid pump alone is sufficient to lubricate the rotating components above the predetermined temperature and sufficient to lubricate the rotating components at or below the predetermined temperature only with splash lubrication.Type: ApplicationFiled: February 15, 2013Publication date: June 19, 2014Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Goro Tamai, Norman Schoenek, Anthony J.

Publication number: 20140162840Abstract: A method and system for controlling anti-jerk of a hybrid vehicle reduce shift vibration and shock by reverse phase controlling a drive motor during gear-shifting of a hybrid vehicle without a torque converter. The method includes determining whether a gear-shifting command is outputted from a transmission control unit of the hybrid vehicle; when it is determined that the gear-shifting command is outputted, confirming a gear-shifting range divided into at least three phases in accordance with the gear-shifting command; determining whether the corresponding divided gear-shifting range is an anti-jerk allowed gear-shifting range; and when it is determined that the corresponding gear-shifting range is the anti-jerk allowed gear-shifting range, reverse phase controlling a drive motor of the hybrid vehicle by a predetermined value in order to reduce or attenuate vibration and shock generated in the corresponding gear-shifting range.Type: ApplicationFiled: October 29, 2013Publication date: June 12, 2014Applicants: Kia Motors Corporation, Hyundai Motor CompanyInventors: Joung Chul Kim, Tai Jin Jugn

Publication number: 20140162839Abstract: In a case of engagement when a clutch K0 disposed between an engine 12 and a motor generator MG is engaged during EV running while a release instruction for the clutch K0 is output, drive of the engine 12 is changed such that a rotation speed NE of the engine 12 approaches a rotation speed NMG of the motor generator MG and, therefore, a drag torque of the engine 12 can be suppressed regardless of an engagement state of the clutch K0, and generation of longitudinal acceleration can be suppressed by reducing a slip time of the clutch K0. Therefore, a control device of a hybrid vehicle 10 can be provided that reduces a driver's uncomfortable feeling in a simplified manner in a case of wrong engagement of the clutch K0.Type: ApplicationFiled: December 24, 2010Publication date: June 12, 2014Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Terufumi Miyazaki, Yukihiko Ideshio, Toshihiko Kamiya, Shingo Eto, Hironori Asaoka, Yasuyuki Kato

Patent number: 8751081Abstract: A hybrid vehicle that runs in an electric running priority mode after the engine reaches a driving condition appropriate for heating the catalyst (S130-S150) if the system has been started up and the following conditions are met: the vehicle is running in an electric running priority mode in which electric power is used preferentially to drive the vehicle; the temperature (Tc) at which the catalyst becomes activated to purify the engine exhaust falls below a threshold value (Tref); and a battery storage rate (SOC) falls below a threshold value (Scd) which reaches a threshold value (Shv). Then the system switches to a hybrid running priority mode after running on electric power for the length of time necessary to heat the catalyst.Type: GrantFiled: May 19, 2009Date of Patent: June 10, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventors: Norihiko Kato, Masaya Yamamoto

Patent number: 8733480Abstract: 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: GrantFiled: August 25, 2008Date of Patent: May 27, 2014Assignees: Kabushiki Kaisha Toyota Chuo Kenkyusho, Toyota Jidosha Kabushiki KaishaInventors: Takao Watanabe, Eiji Tsuchiya, Hiroyuki Nishizawa, Takeshi Kitahata
