御装置。[Scope of 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 by changing the operating friction elements, the gear can be shifted to other gears. An input rotation sensor and an output rotation sensor detect the input rotation speed and output rotation speed of the speed change gear mechanism of the automatic transmission, respectively, and the inertia phase time measuring means detects the input rotation speed and the output rotation speed of the transmission gear mechanism based on the signals from these sensors. , the line pressure adjusting means measures the time during which the gear ratio represented by the ratio between the input and output rotational speeds is changing, and controls the line pressure during the shifting so that the inertia phase time becomes a target value. In the line pressure control device, the adjustment amount is corrected according to the magnitude of the deviation of the inertia phase time from the target value, and the line pressure adjustment means controls the line pressure during the shift based on the adjustment amount. What is claimed is: 1. A line pressure control device for an automatic transmission, characterized in that the line pressure control device is provided with an adjustment amount correction means for performing the adjustment.
