ABSTRACT:
A slip-controlled brake system for automotive vehicles equipped with a deceleration-sensitively actuated brake pressure modulator (1) comprising a shaft (7) rotating together with the wheel (6) and an inert mass (8) arranged on said shaft. If a critical wheel deceleration is exceeded, the inert mass (8) is axially displaced on the shaft (7) by an arrangement comprising a ball (10) and an inclined ramp (9), and the brake pressure in the wheel brake (5) of the associated wheel (6) is, by way of a lever (16) actuating a brake pressure control valve (17), thus controlled, that is maintained and/or reduced. The rotating inert mass (8) which, due to its inertia, at first continues to run at unreduced speed when the control action sets in, is slowed down to the rotational speed of the shaft (7) by a force depending on the instantaneous brake pressure in the wheel brake (5). During the control phase, the reference quantity (v.sub.REF) relevant to the control action is, thereby, adapted to the instantaneous brake pressure and thus to the instantaneous friction coefficient existing between the road surface and the controlled wheel (6).
