摘要： At pre-shift of a shift control, a line pressure control section determines a pressure raising amount ΔPL of a line pressure PL on the basis of a pressure raising amount map stored in a memory, and controls a line pressure controlling linear solenoid valve so that the line pressure PL regulated by a regulator valve is raised by this pressure raising amount ΔPL. For example, a control hydraulic pressure corresponding to the pressure raising amount ΔPL is applied to the regulator valve from the line pressure controlling linear solenoid valve. Thus, hydraulic oil supplied from an oil pump is mostly discharged from an output port for the line pressure PL. Therefore, although there is a possibility that the line pressure PL regulated within a line pressure circuit somewhat varies when stroke of a hydraulic piston starts, a decrease of the line pressure PL is suppressed sufficiently compared with the case where the line pressure PL is not raised as a conventional manner.
