Abstract

A method for controlling a braking force in a regenerative braking joint control system, comprising: Distributing, by means of a control device, braking forces to the front wheels (213) and to the rear wheels (214) by generating a regenerative braking force on at least one of the front wheels (213) and the rear wheels (214) up to a reference deceleration during braking, wherein a regenerative front wheel braking force and a regenerative rear wheel braking force, which are distributed based on a reference brake distribution ratio, are generated and then only the regenerative rear wheel braking force is generated up to a regenerative rear wheel braking force limit (D), characterized by the fact that After the regenerative rear brake force has been increased up to the regenerative rear brake force limit (D), the level of a front brake force is increased only by generating a hydraulic front brake force.
