1. A braking control device applied to a vehicle including a braking device that adjusts a braking force applied to a front wheel and a braking force applied to a rear wheel, in which when the braking force is applied to a first wheel located on a front side in a vehicle advancing direction among the front wheel and the rear wheel, an anti-dive force that is a force that displaces a front portion of a vehicle body in the vehicle advancing direction upward is generated, and when the braking force is applied to a second wheel located on a rear side in the vehicle advancing direction, an anti-lift force that is a force that displaces a rear portion of the vehicle body in the vehicle advancing direction downward is generated; the braking control device comprising:
a load reduction amount derivation unit configured to derive a load reduction amount, which is a reduction amount of an input load from a reference input load due to application of the braking force to the vehicle, such that the load reduction amount increases as a reduction amount of a vehicle braking force increases, wherein the vehicle braking force is the braking force applied to the vehicle, the input load is a load input from the vehicle body to a suspension interposed between the vehicle body and the second wheel, and the reference input load is the input load when the braking force is not applied to the vehicle;
an anti-force derivation unit configured to derive the anti-lift force such that the anti-lift force increases as a second braking force, which is a braking force applied to the second wheel, increases; and
a braking control unit configured to perform a posture braking process of adjusting the second braking force such that a difference between the load reduction amount and the anti-lift force is less than or equal to a difference determination value, and adjusting a first braking force, which is a braking force applied to the first wheel so that the vehicle braking force becomes a required value of the vehicle braking force when the vehicle braking force is reduced under a situation where the vehicle is decelerated by application of the braking force.
