Brake control apparatus with solenoid valve

摘要

In a brake control apparatus according to the present invention, a range of change in a hydraulic pressure with respect to an amount of current applied by a drive signal from a control circuit of an N/O valve provided in a hydraulic path that extends from a hydraulic pressure generation source to a wheel cylinder is set to be smaller than a range of change in a hydraulic pressure with respect to an amount of current applied to an N/C valve provided in a hydraulic path that extends from the wheel cylinder to a reservoir. Accordingly, it is possible to decrease the hydraulic pressure which is generated when the amount of current is minutely varied in the N/O valve, thereby enhancing controllability of the hydraulic pressure. This enables highly accurate hydraulic control.
