Abstract
There is provide a brake control technology according to which a target hydraulic pressure is reliably achieved when a hydraulic pressure is decreased during hydraulic control and brake drag does not occur even when the target hydraulic pressure is zero. In a brake apparatus, a dead-band region is set for the target hydraulic pressure that is used in the hydraulic control. When braking control is switched from the hydraulic control to regenerative control in cooperative braking control, residual pressure reduction control is executed. In the residual pressure reduction control, the target hydraulic pressure is set to a value that is lower than zero to which the hydraulic pressure should be brought.
