Abstract: PROBLEM TO BE SOLVED: To provide a hybrid vehicle which has a power distribution unit connected to an engine and a motor and miniaturizes an electric motor to realize higher output of the engine. SOLUTION: A first motor generator MG1 is connected to a power distribution unit (a second planetary gear device 14) via a reduction gear (a first planetary gear device 12), and the torque generated by the first motor generator MG1 is reduced compared with the power of an engine 6 connected to the power distribution unit in comparison with the case not provided with the reduction gear, and the first motor generator MG1 can be miniaturized. Therefore, even when the engine output is increased, the first motor generator MG1 can be relatively miniaturized. In other words, the first motor generator MG1 can be miniaturized to realize higher output of the engine 6, and favorably mounted on a vehicle. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To control to suppress a counterelectromotive force generated in a coil without causing an increase in the size of a device. SOLUTION: A motor driving device releases the fixing of a stator 12 in a state that a coil 22 of one of the stator 12 is substantially opposed to a permanent magnet 18 when the number of crossing magnetic fluxes to the stator 12 from the permanent magnet 18 is reduced. A current flowing to the coil 22 is controlled so that a magnetic force generated from the coil 22 of the stator 12 repels the magnetic force generated from the permanent magnet 18, and thereby the stator 12 in which the fixture is released is moved to the outside in the radial direction. When the coil 22 of the stator 12 in which the fixture is released is not opposed to the permanent magnet 18, the stator 12 is fixed. This operation is performed at all the stators 12, and all the stators 12 are moved to the outside in the radial direction. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To smoothly switch a torque transmission route from a power source to a drive shaft in a power output device outputting power to the drive shaft and an automobile loaded with the same and having wheels mechanically connected to a drive shaft. SOLUTION: An engine 22, a motor MG1 and the drive shaft 65 are connected to each rotating element of a power distribution integration mechanism 30 constructed to have the four rotating elements by two planetary gears P1, P2 respectively. A motor MG2 is connected to a fourth rotating element to which the engine 22, the motor MG1 and the drive shaft 65 are not connected via a clutch C1, and is connected to the drive shaft 65 via a clutch C2.

Abstract: PROBLEM TO BE SOLVED: To provide a power output device having a proper efficiency and to provide an automobile having the same. SOLUTION: An engine 22 is controlled to be operated so as to set a requested torque T* to be outputted to a drive shaft 64 based on the pressing distance of a driver accelerator pedal 83 and a vehicle speed to be sensed by a vehicle speed sensor 88 and to efficiently output the power to meet the requested torque T*. The speed change gear stage of a transmission 60 is selected so that the torque output from the engine 22 side to the drive shaft 64 becomes the value just near the requested torque T*, and motors MG1, MG2 are controlled to be driven. When the torque output from the engine 22 side to the drive shaft 64 becomes larger than the requested torque T* even when any speed change gear stage is selected, a brake 38 is operated to lock the motor MG1, and the engine 22 is controlled so that the requested torque T* is output by the power from the engine 22. As a result, since the circulation of the power is suppressed, the energy efficiency of the entire power output device can be improved. COPYRIGHT: (C)2004,JPO&NCIPI
