Title:
AUTOMATIC TRANSMISSION
Document Type and Number:
Japanese Patent JP2022115428
Kind Code:
A
Abstract:
To provide an automatic transmission that rises regenerative power generation amount obtained from a motor while suppressing a rapid rise in braking force.SOLUTION: An automatic transmission is equipped with a first gear shift portion into which driving force outputted from an engine is input, a sub shaft connected between the first gear shift portion and an output shaft, a second gear shift portion disposed on a downstream side of the first gear shift portion in a power transmission path transmitting driving force toward the output shaft, a motor that is connected to an intermediate part from a sub shaft to the second gear shift portion in a power transmission path, and performs regenerative power generation, and a gear shift control portion that controls the regenerative power generation amount of the motor so as to change braking force according to the gear shift of the first gear shift portion within a range of a predetermined engine braking force when a vehicle decelerates.SELECTED DRAWING: Figure 2
