BRAKING CONTROL DEVICE FOR VEHICLE

摘要

A vehicle braking control device includes: an indicated-value-setting unit for setting an indicated current value, which relates to a differential pressure valve provided to a channel between a master cylinder and a wheel cylinder, to a value corresponding to a required differential pressure; and a depressurization-starting differential pressure acquisition unit for acquiring, as a depressurization-starting differential pressure, the differential pressure at the point in time when a pressurizing state for increasing the differential pressure caused by the differential pressure valve transitions to a depressurizing state for reducing the differential pressure caused by the differential pressure valve. The area between the depressurization-starting differential pressure and a boundary differential pressure is set as a depressurization-starting differential pressure area. When the depressurizing state is in effect and the required differential pressure is included in the depressurization-starting differential pressure area, the indicated-value-setting unit sets the slope of decrease of the indicated current value.

1. A braking control device for vehicle comprising:
an indicated-value-setting unit configured to set an indicated current value to a differential pressure valve provided at a channel between a master cylinder and a wheel cylinder corresponding to a wheel, to a value according to a required differential pressure having a requirement value of a differential pressure by the differential pressure valve; and a depressurization-starting differential pressure acquisition unit configured to acquire, as a depressurization-starting differential pressure, a differential pressure at transition from a pressurizing state of increasing the differential pressure by the differential pressure valve to a depressurizing state of decreasing the differential pressure by the differential pressure valve; wherein when a depressurizing differential pressure area is set as an area between the depressurization-starting differential pressure acquired by the depressurization-starting differential pressure acquisition unit and a boundary differential pressure having a value obtained by subtracting a predetermined differential pressure according to the depressurization-starting differential pressure from the depressurization-starting differential pressure, the indicated-value-setting unit sets a slope of decrease of the indicated current value, as an amount of decrease of the indicated current value relative to an amount of decrease of the required differential pressure, to be gentler as the depressurization-starting differential pressure is smaller, when the required differential pressure is included in the depressurizing differential pressure area in the depressurizing state.
