Abstract: The inventive vehicle braking control device performs a brake assist control of increasing a braking force for avoiding a collision of a vehicle at a more appropriate time. The device comprises a portion which acquires an estimated time until a vehicle reaches to an obstacle; a portion which judges based on a braking operation amount and a braking operation speed value if the driver performed an urgent braking operation; and a portion which determines the start of a braking force assist control when an urgent braking operation is judged in a case that the estimated time is less than a first predetermined time, wherein, if the estimated time is less than a second predetermined time shorter than the first predetermined time, the urgent braking operation is judged when the braking operation amount exceeds a threshold value irrespective of the braking operation speed value.
