Abstract
The hydraulic pressure control device has an idle region, and is provided with a control portion, and a correcting portion which, in cases when the reaction time of the actual pressure to pressure increasing control or pressure decreasing control exceeds a predetermined threshold time, corrects a control current towards the side in which the flow-rate is increased. In cases when a judging portion has judged that the pressure increasing control is in the idle area, the correcting portion applies, as the threshold time, an idle threshold time set to a value different from the threshold time that in cases when the judging portion has not judged that the pressure increasing control is in the idle area. Furthermore, in cases when the reaction time of the actual pressure to the pressure increasing control exceeds the idle threshold time, the correcting portion corrects the control current.
