[Object] To provide a brake fluid pressure control device for a vehicle that can improve brake responsiveness when a brake is re-operated by a driver during ABS control, thereby reducing a driver's feeling of wrongness and strangeness. [Solution] Provided is a brake fluid pressure control device for a vehicle that includes a wheel speed obtaining device to obtain wheel speed, and a vehicle body deceleration calculating means to calculate a vehicle body deceleration on the basis of the wheel speed. If a condition is satisfied in which the vehicle body deceleration continues to stay at a low rate of less than or equal to a predetermined threshold value for a predetermined period of time, the pressure increasing rate in pressure increasing control is altered to a higher value than before the condition is satisfied. [Effect] The brake fluid pressure of a brake caliper (CAL pressure) can quickly be brought close to the fluid pressure of a master cylinder (M/C pressure). Therefore, it is possible to improve the brake responsiveness when the brake is re-operated by the driver during the ABS control, thereby reducing the driver's feeling of wrongness and strangeness.
