Patent ID: 8303046

Claim:
A brake apparatus comprising: a regenerative brake unit that generates a regenerative braking force by executing regenerative control over an electric motor; a hydraulic brake unit that generates a hydraulic braking force by executing hydraulic control over a hydraulic fluid; and a control unit that controls the regenerative brake unit and the hydraulic brake unit in such a manner that a required braking force, which is calculated based on a brake operation performed by a driver, is achieved, wherein the control unit sets a dead-band region for a target hydraulic pressure that is used in the hydraulic control, and controls a hydraulic pressure of the hydraulic fluid using the dead-band region, and wherein when a predetermined residual pressure reduction condition for adjusting an actual hydraulic pressure to the target hydraulic pressure is satisfied while the hydraulic pressure is decreased, the control unit executes residual pressure reduction control in which the target hydraulic pressure is set to a temporary value that is lower than an actual target value to which the hydraulic pressure needs to be adjusted, and the control unit maintains the set target hydraulic pressure at the temporary value during a predetermined period, wherein the temporary value, to which the control unit sets the target hydraulic pressure, is lower than the actual target value by an amount corresponding to a dead-band width of the dead-band region in the residual pressure reduction control such that the dead-band region shifts.
