Title:
Control device for automatic transmission
Document Type and Number:
Japanese Patent JP6330194
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a controller of an automatic transmission enabling seamless shift while suppressing hitting sound.SOLUTION: When a controller of an automatic transmission performs seamless shift, an axial movement speed of a shift actuator at the time of moving a high-speed clutch ring to an axial engagement side in a state where a low-speed clutch ring dog and a dog of a low-speed side relative rotation body are engaged with each other, is accelerated as a relative rotational frequency of a high-speed side relative rotation body becomes larger.SELECTED DRAWING: Figure 4
