PROBLEM TO BE SOLVED: To provide a control device for an automatic transmission, which can improve fuel economy by quickly determining whether a road is up-hill road or not, immediately performing neutral control upon making stop on a flat road or a downhill road, and appropriately adjusting the joining pressure of a clutch on an up-hill road according to a braking force.SOLUTION: Up-hill road determination means 24 determines whether a road is up-hill road or not based on immediate detection angle information detected by road surface gradient angle detection means 21, 34, and 35 until smoothing processing of a processing part 23 is completed after control conditions have been established, and determines whether the road is up-hill road or not based on processing angle information subjected to smoothing processing after the completion of the smoothing processing. Control means 20 executes, when the control conditions are established and a traveling road is up-hill road, joining pressure control of a clutch 43 based on the detection angle information or the processing angle information used for the up-hill road determination of the up-hill road determination means 24, and a braking force Bf. |
