180650270 | Control of external device in conjunction with specific hybrid function | 7 |
20100230193 | PLUG-IN VEHICLE FUNCTION INDICATION - A vehicle having a vehicle body has an interior portion with a plurality of trim components. A plurality of windows are supported on the body and positioned next to the interior portion. An electrical charging system having a rechargeable battery is attached to the vehicle body and configured to receive an electrical charge from at least one of an on-board charger, an external charger or a charging station. A display panel is connected to the electrical charging system and mounted on one of the trim components. The display panel is configured to display information indicative of a status of the electrical charging system. The display panel is disposed in a position such that the information is visible from a position exterior to the vehicle body. | 09-16-2010 |
20100320018 | Method And System To Prevent Vehicle Driveaway During Battery Charging - 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. | 12-23-2010 |
20100320019 | SYSTEM AND METHOD TO PROVIDE LUBRICATION FOR A PLUG-IN HYBRID - 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. | 12-23-2010 |
20110174559 | CONTROL APPARATUS AND METHOD FOR CONTROLLING A HYBRID VEHICLE - A hybrid vehicle is taught herein in which a clutch is disposed between an engine and a motor/generator and disengagement of the clutch is controlled in a coasting drive while dragging the engine. A drive controller engages the clutch so that the vehicle coasts while dragging the engine at a time of coasting deceleration. While coasting, when the stepped transmission of the hybrid vehicle downshifts, the clutch is disengaged during the downshift. | 07-21-2011 |
20110240385 | Hybrid module for a vehicle - An apparatus for a hybrid vehicle is disclosed. The apparatus has a detachable module including an energy storage device and a module drive device connected to the energy storage device, the module drive device configured to convert between electrical energy and mechanical energy. The apparatus also has an energy recovery device electrically connected to the energy storage device. The apparatus additionally has a mechanical connector selectively connecting the module drive device to a vehicle powertrain, wherein the module drive device drives the powertrain via the mechanical connector. | 10-06-2011 |
20110315462 | DRIVE-TRAIN WITH AN AUTOMATED GROUP-TRANSMISSION - A drivetrain of a motor vehicle, with a hybrid drive, comprising an internal combustion engine and an electric machine and a semi-automatic group transmission. The semi-automatic group transmission comprises at least a main transmission and a downstream group in drive connection downstream with the main transmission. An input shaft of the semi-automatic group transmission is connected, via a controllable starting clutch, to the internal combustion engine of the hybrid drive and an output shaft of the semi-automatic group transmission is connected to an axle drive. Depending on the shift position of at least one shifting element, the electric machine can be coupled to the force flow or the torque flow of the drivetrain between the main transmission and the downstream group of countershaft design and/or between the downstream group of a countershaft design and the axle drive. | 12-29-2011 |
20120168238 | METHOD AND APPARATUS FOR HYDRAULICALLY DEACTIVATING A TORQUE TRANSFER CLUTCH - A torque transfer apparatus for a transmission includes a rotatable friction clutch pack including a first friction plate that is contiguous to a second friction plate, with the first friction plate coupled to a first transmission element and the second friction plate coupled to a second transmission element. A Belleville spring device is configured to urge the first friction plate to engage the second friction plate to effect torque transfer therebetween when a hydraulically-activated piston is deactivated. The hydraulically-activated piston is configured to urge the second periphery of the Belleville spring device away from mechanical contact of the first friction plate when the hydraulically-activated piston is activated. | 07-05-2012 |
