ABSTRACT:
A hydraulic control system for an automatic transmission detects the rotating speed of the parts whose rotating speed varies due to shifting, and controls the transitional oil pressure applied to the frictionally engaging device in the automatic transmission so that the detected rotating speed matches the locus of the target rotating speed that said parts should follow after the shift command is outputted. Thus, the optimum shifting transitional characteristics can be obtained regardless of the inherent differences among otherwise identical vehicles which differences are created at the time of manufacturing or vary with time and vehicle use.
