<p>A booster (3) and a pressure amplifying device (10) are provided as devices performing a brake assist. Further a pressure sensor (27) which detects master-cylinder pressure is provided. While the braking is applied to the vehicle, the malfunction of the booster (3) can be detected based on master-cylinder pressure detected by the pressure sensor. If the malfunction of the booster (3) is detected, a pump (15) in the pressure amplifying device is driven as an substitute for the booster (3). As a result, a required brake assist can be performed to ensure high braking force. Accordingly, the brake control apparatus can enhance safety during the vehicle running. <IMAGE></p> |
