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 realize a driving torque estimation controller and a method capable of estimating drive torque at high accuracy even if the device is applied to a drive system of a four-wheel drive vehicle system. SOLUTION: An estimated torque switching unit 48 switches estimated torque of a pump torque estimating unit 40 and an engine torque estimating unit 41 by a judging signal of a judging unit 47, and an estimated torque type judging unit 49 inputs engine torque Te from the estimating unit 41 into a block 50. The block 50 reads accessory torque Tacc stored in an accessory torque storing unit 46 and calculates pump torque Tp. The estimated torque type judging unit 49 inputs torque Tp estimated by the estimating unit 40 into a block 52. A block 56 outputs a correction factor (k) through a block 57 by finding a transmitting efficiency correction factor K' by using a four-wheel drive distributing command signal X and the transmission efficiency correcting factor k'. The direction factor (k) is multiplied by To in a block 54, correction output shaft torque Tk is found, the final gear ratio rf is multiplied in a block 55, and drive wheel torque TD is calculated.
