[Object] To provide a brake fluid pressure control device for a vehicle that can accurately determine, with a simple method, whether the coefficient of friction of the travelling road surface to tires has suddenly changed from a low coefficient of friction to a high coefficient of friction. [Solution] Provided is a brake fluid pressure control device for a vehicle that can perform fluid pressure control on the brake fluid pressure applied to wheel brakes. It is determined whether the pressure increasing time in the current pressure increasing control exceeds determination time which is set on the basis of the pressure increasing time in past pressure increasing control. If the pressure increasing time in the current pressure increasing control exceeds the determination time, it is determined that the road surface on which the vehicle is travelling has changed from the road surface with a low coefficient of friction to the road surface with a high coefficient of friction. [Effect] It is possible to accurately determine, with a simple method, whether the road surface on which the vehicle is traveling has suddenly changed from a road surface with a low coefficient of friction to a road surface with a high coefficient of friction.
