<p><P>PROBLEM TO BE SOLVED: To provide a brake control device that controls the decrease of hydraulic oil by leakage and secures a braking force. <P>SOLUTION: The brake control device is provided with a hydraulic actuator, which controls the hydraulic pressure in a wheel cylinder; a control means, which calculates target hydraulic pressure in the wheel cylinder and controls the hydraulic actuator based on the target hydraulic pressure; a hydraulic pressure source provided in the hydraulic actuator; a diaphragm provided with a predetermined flow passage area; and a hydraulic pressure detection means, which detects the actual hydraulic pressure in the wheel cylinder. The control means calculates deviation between the target hydraulic pressure and the actual hydraulic pressure in the wheel cylinder for each of a plurality of wheels and when the deviation is more than a predetermined value, the deviation is judged abnormal. When the hydraulic pressure deviation is judged abnormal, the supply of the hydraulic oil from the hydraulic pressure source to the wheel cylinder, in which the hydraulic pressure deviation is judged abnormal, is interrupted. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
