PROBLEM TO BE SOLVED: To provide a break fluid pressure control device for a vehicle, capable of determining that emergency brake operation is executed without using signals from a master cylinder pressure sensor or a brake pedal sensor.SOLUTION: The break fluid pressure control device for a vehicle includes: calculation means (S2) for calculating the amount of wheel speed change of front wheels and the amount of a wheel speed change of rear wheels; first determination means (S4) for, on the basis of the amount of wheel speed change of the front wheels and the amount of wheel speed change of the rear wheels, determining whether or not a first condition in which the front wheels are decelerated preceding the rear wheels is satisfied; second determination means (S10, S11 and S12) for determining whether or not a second condition in which each of the amounts of wheel speed change has been larger than a first threshold value continuously for a predetermined period of time T3 is satisfied; and brake assist control means (S15) for, when the first condition and the second condition are satisfied, determining that emergency brake operation is executed and executing brake assist control. |
