Abstract

A method of wear-dependent braking force distribution prevents adhesion problems without being limited to lowest brake pressures as is the case with conventional methods. Wear control is dispensed with only in the case of operationally very rare braking actions, for example, those above 0.3 g or a learned adhesion threshold. These rare braking actions are limited, in practice, to genuinely critical braking situations. Otherwise, the control interventions are carried out with to produce balanced wear only in the long term; an attempt is made to achieve wear at the same rate rather than simply balanced wear.
