1. A vehicular braking force control system comprising:
a plurality of actuators capable of generating a braking force for a vehicle;
a coasting state detection unit configured to detect that a coasting state, which is a state where an accelerator operation is not performed and a brake operation is not performed during running of the vehicle, has been established;
a target braking force calculation unit configured to calculate a target braking force on the basis of a state of the vehicle when the coasting state detection unit detects that the coasting state has been established; and
a braking force distribution control unit configured to determine a distribution braking force that is a braking force to be caused to be generated by each actuator, such that the distribution braking force is equal to or less than a braking force generable by the actuator and a sum of the distribution braking forces is equal to the target braking force, and to perform control of causing each actuator to generate the distribution braking force.
