摘要： A vehicle braking device performs a following control which makes an actual value of a physical quantity follow a first target value when the actual value of the physical quantity is a value outside a dead zone and a suppression control which suppresses a change of the actual value when the actual value is a value within the dead zone in order to control the physical quantity associated with the braking force to be the first target value. The vehicle braking device comprises a setting portion which sets a second target value which follows the first target value and which is smaller than the first target value, when the first target value is increasing and a control portion which performs a control to make the actual value approximate the second target value.

摘要： 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.
