Control device of automatic transmission

摘要

Provided is a control device of an automatic transmission (2000) in which motive power of a power source (1000) is transmitted via a fluid coupling (3200) and a plurality of gears are implemented based on combination of engagement and disengagement of a plurality of frictional engagement elements (3610, 3620, 3630, 3640, 3650, 3660). The control device comprises a detection unit (8000) detecting a difference in a revolution speed calculated by subtracting an input shaft revolution speed (NT) of the automatic transmission (2000) from a revolution speed (NE) of the power source (1000), and a control unit (8000) modifying a manner of control of the frictional engagement element in correspondence with the difference in the revolution speed detected by the detection unit (8000). The control unit (8000) modifies engagement start timing of the frictional engagement element.
