Abstract
A vehicle braking apparatus is capable of suppressing time lag at the time of activating an ABS, reliably detecting wheel slippage at a wheel even on a low μ road surface, and performing a brake operation to stop the vehicle without causing stroke variations in a brake actuating unit. A vehicle braking apparatus includes a hydraulic modulator for generating hydraulic pressure applied to a brake caliper which is connected to a master cylinder via a main brake path, and a pressure sensor for detecting hydraulic pressure applied to the brake caliper. When the ABS is activated, the hydraulic pressure applied to the brake caliper is reduced to a pressure reduction target value based on the detected pressure. A normally-open electromagnetic valve lies in the main brake path. The brake path pressure on each side of the valve is equalized by means of the hydraulic modulator before opening the electromagnetic valve.
