<P>PROBLEM TO BE SOLVED: To provide a hydraulic control device capable of quickly and stably achieving a target oil pressure value, avoiding repetition of an excessive overshoot and an excessive undershoot. <P>SOLUTION: In a hydraulic control system including the feedback control, when raising or lowering the oil pressure toward a target oil pressure value, a provisional target oil pressure value higher (or lower) than the target oil pressure value is temporarily given as a target. Before the real oil pressure value exceeds the target oil pressure value, the target is changed to the target oil pressure value so as to quickly converge the real oil pressure value to the target oil pressure value, restricting outbreaks of overshoot. <P>COPYRIGHT: (C)2012,JPO&INPIT |
