Abstract

A braking force control apparatus is provided which has an upstream braking actuator for generating an upstream pressure common to four wheels, a downstream braking actuator individually controlling braking pressure supplied to braking force generating devices of the wheels using the upstream pressure, and a control unit. When the downstream braking actuator is abnormal and the upstream pressure can be supplied to the braking force generating devices, but a braking pressure of any one of the wheels cannot be normally controlled, the control unit selects a control mode on the pressure increasing side out of the front wheel control modes, selects a control mode on the pressure increasing side out of the rear wheel control modes, selects a control mode on the pressure decreasing side out of the two selected control modes as a prescribed control mode, and controls the upstream pressure in the prescribed control mode.
