(57) [Abstract] [Purpose] Slip the clutch when racing range shifts from N range to D range or R range, or when the accelerator is depressed immediately after shifting from N range to D range or R range. Provided is a control device for an automatic transmission that can be effectively prevented. In a power plant including an engine CE and an automatic transmission AT, when shifting from an N range to a D range or an R range, the control unit C reduces the output torque of the engine CE for a predetermined time, As a result, the amount of torque supplied from the engine side to the automatic transmission side is reduced, and even if the line pressure is low, such as during racing select, slippage or seizure of the clutch engaged in the shift is prevented, and the clutch Increased durability. |
