摘要： PROBLEM TO BE SOLVED: To provide an automatic transmission capable of realizing smooth and efficient transmission control without using a clutch by incorporating a motor in the transmission and controlling torque and the number of revolutions. SOLUTION: A first gear row input shaft of the parallel shaft type transmission having two sets of gear shift gear rows is connected with an engine, a second gear row input shaft is connected with the engine through a motor, and torque of the first gear row is temporarily moved to the second gear row by the motor to switch a gear of the first gear row during that time. Gear ratio of the second gear row is used as an intermediate step of gear ratio of the first gear row to reduce motor capacity and battery capacity and dispense with the clutch in order to provide the economical transmission device. Torque transition gear shift for up-shift and down-shift becomes possible by performing active gear shift by the motor. Moreover, jumping-over gear shift so far impossible conventionally becomes possible to obtain continuous ratio in order to improve driving property. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide an active speed changing and controlling system which can reduce a capacity of a motor, and is low-priced. SOLUTION: In the active speed changing system, the engine power is reduced such that the driving force before the speed-changing is approximately equal to the driving force after the speed-changing estimated on the assumption that the transmission has been shifted to the next stage gear keeping the engine power constant. While the engine power is being reduced, the engine power is switched over to the next stage gear by controlling the torque and rotational speed of the motor. After the switching-over is completed, the engine power is returned to the original value. COPYRIGHT: (C)2005,JPO&NCIPI
