イン圧制御装置。[Claim for Utility Model Registration] Various friction elements of a transmission gear mechanism are selectively hydraulically activated by line pressure to select a predetermined gear, and in response to a gear change command, the operating friction elements are changed to shift to other gears. An automatic transmission configured to change gears includes an input rotation sensor that detects the input rotation speed of the speed change gear mechanism, an output rotation sensor that detects the output rotation speed of the speed change gear mechanism, and the input rotation sensor that detects the input speed based on signals from these sensors. an inertia phase start detection means for detecting when a gear ratio expressed as a ratio between output rotational speeds has started to change toward a gear ratio after shifting; A line pressure control device for an automatic transmission, comprising: a line pressure adjusting means for increasing the line pressure during gear shifting after the set time has elapsed if the line pressure has not been started.
