ABSTRACT:
A vehicle braking force controller for controlling braking force of a vehicle by changing brake fluid pressure effected by a fluid pressure controller has a deceleration detector and a computer. The computer calculates a vehicle deceleration, a target deceleration of the vehicle, and a pressure adjustment speed at which the brake fluid pressure increases or decreases using the target deceleration and the vehicle deceleration. The pressure adjustment speed calculator calculates the brake fluid pressure adjustment speed using a brake fluid pressure adjustment volume which is proportional to a difference between the detected vehicle deceleration and the calculated target deceleration, and a target tracking time representing a time required to adjust the brake fluid pressure with the pressure adjustment volume. The computer controls the brake fluid pressure according to the pressure adjustment speed. Thus, the vehicle braking force controller quickly starts the deceleration so that the actual vehicle deceleration does not overshoot the target deceleration.
