Abstract
A vehicular brake control device makes it possible to detect a failure or malfunction in closing an electromagnetic valve which is placed between a master cylinder and each of wheel cylinders. The vehicular brake control device includes a pressure application device which is capable of applying a hydraulic pressure automatically, i.e., regardless of a brake pedal depression, to each of wheel cylinders by way of a hydraulic pressure control device from a master cylinder and an ECU which drives the pressure application unit and the hydraulic pressure control device to adjust a braking force of each of wheels. The hydraulic pressure control device includes a set of pressure-maintaining and pressure-reducing valves for each wheel. The ECU has a pressure application check division which begins to check the pressure application at a predetermining timing.
