Abstract
A controller for an automatic transmission hydraulic clutch includes a hydraulic clutch engaged by hydraulic pressure, a hydraulic pressure control valve for regulating the hydraulic pressure, and a detector for detecting a condition immediately before engagement of the hydraulic clutch based upon a change in the hydraulic pressure. A timing controller adjusts timing to change a control force in the hydraulic pressure control valve in response to detection of a condition immediately before engagement of the clutch.
