Abstract
A vehicle braking force control device includes a braking force control unit. The braking force control unit is configured to shift to a drive state so as to use an auxiliary power source when a main power source fails, and to limit current outputted to an electric actuator of a braking device for producing braking hydraulic pressure when a transition is made to the drive state using the auxiliary power source. The braking force control unit has two current limit values used during actuation of the electric actuator by the auxiliary power source, the current limit values being a first current limit value for ensuring increased-braking-hydraulic-pressure characteristics, and a second current limit value for ensuring a necessary minimum braking hydraulic pressure, the second current limit value being less than the first current limit value.
