Abstract

A brake control apparatus obtains a required braking force using a hydraulic braking force in combination with a regenerative braking force. The brake control apparatus includes a hydraulic brake unit that controls the hydraulic braking force. When the deviation of an actual hydraulic pressure from a target pressure falls outside a permissible range (d), the hydraulic brake unit controls the actual hydraulic pressure in such a manner that the deviation falls within the permissible range. On the other hand, when the deviation is within the permissible range (d), the hydraulic brake unit maintains the actual hydraulic pressure. The hydraulic brake unit includes a control unit that detects timing (Ta) at which usage of the hydraulic braking force needs to be started to compensate for a deficiency from the required braking force, and that raises (r) the target pressure at the detected timing (ta).
