ABSTRACT:
In an automatic braking force control apparatus for a vehicle employing a deceleration feedback control system and an anti-skid control system executing, irrespective of a desired braking force for deceleration feedback control, an anti-skid cycle for preventing a wheel lock-up condition, the feedback control system calculates a desired braking force as a sum of a proportional-control signal component proportional to an error signal corresponding to a deviation from a desired deceleration, and an integral-control signal component corresponding to the integral of the error signal. The feedback control system memorizes the desired braking force, calculated just before an anti-skid cycle start time, as a memorized value, and initializes the desired braking force of an anti-skid cycle termination time to a predetermined value substantially corresponding to the memorized value for preventing a change in the desired deceleration occurring during the anti-skid cycle from being reflected in a feedback control signal.
