Abstract
This braking control device 35 controls a braking device 80 of a vehicle 90. The braking device 80 has: a pressure-regulating reservoir 306 into which a brake fluid released from wheel cylinders 11L, 11R, 12L, 12R flows; and an electric pump 304 that suctions and discharges the brake liquid from the pressure-regulating reservoir 306. When deceleration slip occurs in a wheel of the vehicle 90, the braking control device 35 starts a pressure-reducing process to release the brake fluid from the wheel cylinder corresponding to said wheel and to drive the electric pump 304 at a first discharge speed. The braking control device 35 drives the electric pump 304 at a second discharge speed lower than the first discharge speed when the pressure-reducing process is started for at least one of the front wheels in a state in which the required braking force for the vehicle 90 has not increased.
