20090029824 | Drive apparatus for vehicle - A drive apparatus for vehicle, available to be minimized, is provided. A first planetary gear set (differential device) | 01-29-2009 |
20090076694 | CONTROLLER OF DRIVER FOR VEHICLE - A control apparatus for a vehicular drive system arranged to electrically transmit a portion of an output force of an engine through an electric path, which control apparatus is configured to reduce loads of components associated with the electric path and to restrict a temperature rise of the components associated with the electric path, making it possible to reduce the required size of a cooling system. | 03-19-2009 |
20090082151 | DRIVE DEVICE FOR VEHICLE AND METHOD OF ASSEMBLING THE SAME - A vehicular drive system including a first electric motor, a power distributing mechanism, and a second electric motor disposed on a first axis, and an automatic transmission portion disposed on a second axis parallel to the first axis, and a power transmitting member at an end of the first axis remote from an input rotary member and a rotary member at an end of the second axis remote from the input rotary member are connected to each other through a drive linkage, thereby a total axial dimension of the first electric motor, power distributing mechanism, and second electric motor and an axial dimension of the automatic transmission portion are substantially equal to each other, whereby the axial dimension of the drive system is reduced. A housing of the vehicular drive system includes mutually separate first, second, third, and fourth casing portions, so the drive system can be easily assembled. | 03-26-2009 |
20090098969 | DRIVE DEVICE FOR VEHICLE - A miniaturized vehicular drive apparatus is provided with a reduced size in an axial direction without increasing the number of parallel shafts. A first electric motor M | 04-16-2009 |
20090318261 | VEHICLE DRIVE DEVICE CONTROLLER - In a vehicle driving apparatus including a differential mechanism capable of executing a differential action, a control device can make the driving apparatus small-size, improve fuel consumption, and increase output torque. A transmission mechanism can be switched to a continuously variable shifting state and a step variable shifting state, by a switching clutch or a switching brake. Also, with a switch control bringing the switching clutch into a half-engaged state, during an engine startup/running, while the differential portion is allowed to operate as the electrically controlled continuously variable transmission, a reaction force against an engine torque is generated by the half-engaged switching clutch. Thus, the engine torque not less than the torque bearable by a first electric motor can be inputted into the differential portion, thereby increasing the output torque. | 12-24-2009 |
20100222171 | VEHICULAR DRIVE SYSTEM - A vehicular drive system accommodated in a housing and including a first input shaft that receives a vehicle drive force generated by a vehicle drive power source, and a differential mechanism operable to distribute the vehicle drive force received from the first input shaft to a first electric motor and a second input shaft. The first and second input shafts are disposed coaxially with a first axis such that the second input shaft is disposed downstream of the first input shaft. The first input shaft is rotatably supported by a first support portion provided on the housing and an axial end portion of the second input shaft, and the second input shaft is rotatably supported by a third support portion and a fourth support portion that are provided on the housing. | 09-02-2010 |

20080254935 | Hybrid driving apparatus with multistage transmission provided in power transmission path and control method thereof - When a sub transmission mechanism is switched to the LO-side gear stage, a hybrid control unit executes a control operation such that vehicle speed does not exceed limit vehicle speed determined in advance in accordance with the transmission gear ratio of LO-side gear stage. Specifically, the hybrid control unit reduces at least one of the driving torque generated by the engine and the second motor generator, so that rotation speed of the second motor generator does not exceed tolerable rotation speed. Further, the hybrid control unit reduces at least one of the driving torque generated by the engine and the second motor generator when any of temperatures respectively detected by temperature sensors exceed corresponding upper limit temperatures. | 10-16-2008 |
