<P>PROBLEM TO BE SOLVED: To provide a brake control device capable of suppressing vibrations which may be generated in a solenoid valve. <P>SOLUTION: The brake control device includes: a wheel cylinder into which brake fluid is supplied to add braking force to wheels; a solenoid valve connected to the wheel cylinder through a flow passage, and adjusted by energizing control in an opening; and a control portion controlling to energize an pulse signal which is pulse width modulation controlled to the solenoid valve. The control portion makes the frequency of the pulse signal energized to the solenoid vale higher than a predetermined normal frequency when the generation of self-excited vibrations in the solenoid vale is estimated. <P>COPYRIGHT: (C)2011,JPO&INPIT |
