Abstract: A vehicle braking force control device for executing a follow-up (or servo) control of braking force for individual wheels is improved for canceling the difference of braking force between left and right wheels especially during transient condition of braking force variation due to the difference of input-output response characteristics in braking force generating apparatuses and components associated therewith in a braking system. In the inventive control device, a relation between actual values of braking force on left and right wheels, such as the difference between braking force or pressure values on the left and right wheels, is fed back to these braking force generating apparatuses through the modification of target barking force or pressure values. The modification amounts of the target values may be determined so as to keep appropriate braking force distribution among front and rear wheels.
