Abstract: This braking control device pumps a brake fluid from a reservoir to each wheel cylinder by one fluid pump and includes an electric motor which drives the fluid pump; and a controller which controls the electric motor. The controller calculates a target fluid pressure on the basis of at least one among the vehicle wheel speed, the vehicle deceleration state, and the turning state of the vehicle, calculates a target discharge amount for the fluid pump on the basis of the target fluid pressure, and controls the electric motor on the basis of the target discharge amount. The controller has a front wheel calculation map of the relationship between the fluid pressure and the inflow volume of the brake fluid corresponding to a front wheel cylinder, and a rear wheel calculation map corresponding to a rear wheel cylinder, and calculates the target discharge amount on the basis of the maps.
