Patent number: 7878282Abstract: A control device for hybrid vehicle is provided with property alter means 88 that is operative based on whether or not an EV running mode is set and alters a given property used for determining demanded output torque TOUTt of a transmission mechanism by referring to an accelerator opening Acc. This suppresses occurrence of engine startup to meet a requirement for the EV running mode to be initiated. The property alter means alters the given property such that during an EV running mode turn-on state, demanded output torque TOUTt determined based on the accelerator opening Acc has a lower value than that set for an EV running mode turn-off state. That is, this causes a drop in sensitivity of demanded output torque TOUTt determined based on the accelerator opening Acc. Thus, the occurrence of engine startup induced upon depressive operation of an accelerator pedal during the EV running mode is suppressed.Type: GrantFiled: January 15, 2008Date of Patent: February 1, 2011Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kenta Kumazaki, Tooru Matsubara, Atsushi Tabata

Patent number: 7865287Abstract: There is described hybrid powertrain operation and control. Preferred power flows from an engine to an electro-mechanical transmission and from an energy storage system to an electric machine are determined based upon an operator torque request. Operation of the engine, the electric machine, and the electro-mechanical transmission are controlled to substantially meet the operator torque request. Actual power flow from the energy storage device is monitored. The power flow from the engine is adjusted based upon a difference between the actual and preferred power flows from the energy storage device.Type: GrantFiled: March 29, 2007Date of Patent: January 4, 2011Assignee: GM Global Technology Operations, Inc.Inventor: Steven C.

Patent number: 7857081Abstract: A control system for a hybrid vehicle in which, even if during traveling of the hybrid vehicle, a battery defect arises in a high-voltage power source, battery-less emergency traveling can be achieved over a sufficiently long distance, and the steering assist force can be effectively prevented from changing rapidly during traveling. The control section includes high-voltage power source defect processing unit. During execution of a mode in which the high-voltage power source, is reduced so that the reduced voltage is supplied to an electric power steering device (EPS), when a defect occurs in the high-voltage power source, the high-voltage power source defect processing unit shifts to a mode in which the low voltage of a low-voltage power source is increased so that the increased voltage is supplied to the EPS. The high-voltage power source defect processing unit then disconnects the high-voltage power source and the driving circuit from each other.Type: GrantFiled: July 10, 2009Date of Patent: December 28, 2010Assignee: Toyota Jidosha Kabushiki KaishaInventor: Takeshi Kishimoto

Publication number: 20100320018Abstract: A system and method are disclosed for preventing driveaway or roll away of a plug-in electric vehicle when it is being charged or is coupled to an external power supply cord. When it is detected based on at least one of the following conditions: a current is flowing to the battery charger, a voltage source is coupled to the battery charger, an access door allowing access to the receptacle on board the vehicle is open and/or a plug detect switch indicates that a plug is coupled with the receptacle, a mechanical restraint on the driveline is prevented from being released. The mechanical restraint may be a parking brake. Alternatively, the mechanical restraint may include preventing the gear shift selector from being moved out of the park position.Type: ApplicationFiled: June 18, 2009Publication date: December 23, 2010Applicant: Ford Global Technologies, LLCInventors: Thomas M.

Publication number: 20100320019Abstract: In hybrid electric vehicles having increased battery storage capacity and plug-in capability, electric-only operation of significant duration is available. To supplement lubrication for the electric and mechanical component provided by an engine-driven mechanical pump, an electric pump is provided in parallel to the mechanical pump. A method to control the electric pump is also disclosed in which a first desired quantity of a first component and a second desired quantity of a second component are determined. The electric pump is commanded to provide the greater of the first and second quantities. The desired quantity can be based on preventing temperature in the component from exceeding a maximum design temperature and/or providing sufficient lubrication to rotating parts of the component.Type: ApplicationFiled: June 22, 2009Publication date: December 23, 2010Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventors: Allan Roy Gale, Michael W.
