PROBLEM TO BE SOLVED: To prevent erroneous determination that a road is a split road even if there is a difference in frictional force between tires of right and left wheels and a road surface, in a brake liquid pressure control device for a vehicle controlled so that differential pressure between brake liquid pressures of right and left wheel brakes becomes allowable differential pressure or less in the split road of an anti-lock brake control state.SOLUTION: Wheel deceleration calculating means 25A, 25B, 25C and 25D individually calculate wheel deceleration of front wheels and rear wheels in a value of attaching a minus sign. A split road determining means 28 determines the road as the split road when a maximum value of the wheel deceleration calculated by the wheel deceleration calculating means 25A-25D is a first predetermined value or more and a difference in the wheel deceleration between right and left front wheels or right and left rear wheels existing in an anti-lock brake control state is a second predetermined value or more, when starting anti-lock brake control of at least one of the right and left front wheels, or at least one of the right and left rear wheels. |
