  "textContent": "A brake fluid pressure control device for a vehicle includes a wheel speed acquisition device that acquires a wheel speed, an estimated vehicle body speed calculation device that calculates an estimated vehicle body speed on the basis of the wheel speed, and a bad road determination device that determines whether a road surface of travel is a bad road. The brake fluid pressure control device for a vehicle can provide hydraulic control of a brake fluid that is used in wheel brakes, and the bad road determination device determines whether the road surface of travel is a bad road on the basis of the deviation between the estimated vehicle body speed and the wheel speed. The present invention can detect phenomena particular to bad roads, and can more accurately perform bad road determination, and allows for the improvement of control such as ABS control.",
