摘要： In a method of controlling the brake pressure in an anti-lock vehicle brake system (ABS system), wherein the rotational behavior of a braked wheel is measured and the brake pressure is lowered in response to the slip and/or rotational retardation of the wheel if threshold values are exceeded, and is subsequently raised again and then kept constant during a phase of steady pressure, it is provided that the duration (t1H, t2H . . . t5H) of the pressure stability phase is adjusted in response to a comparison of the pressure reduction periods (t1DOWN, t2DOWN . . . ) and/or the pressure build-up periods (t1UP, t2UP . . . ) of the instantaneous control cycle (1,2 . . . 5) with those of at least one preceding control cycle in order to obtain shorter stopping distances.

摘要： An anti-skid brake system has a first brake circuit (I) terminating at two wheel brakes and connected to a dual-circuit master cylinder, a brake pressure modulation valve assembly and a recirculating pump. In an anti-skid situation, in order to reduce brake pressure, fluid is withdrawn from the two wheel brakes by the brake pressure modulation valve assembly and then returned to the master cylinder by the recirculating pump. Associated with a second brake circuit (I), which is likewise connected to the master cylinder and which terminates at two other wheel brakes, is a floating piston assembly connected to the first brake circuit (I). In an anti-skid situation, a pressure reduction, which is performed in the first brake circuit (I) by the brake pressure modulation valve assembly brings about a pressure reduction in the second brake circuit (II), via the floating piston assembly.

摘要： To permit operation of an anti-skid or anti brake-lock system with wheels having dual braking cylinders, controlled by separate braking valves, control signals to control separate brake valves (V.sub.11, V.sub.12) at respective sides of the vehicle are derived for a first braking system (I) in accordance with well known technology, based on wheel acceleration, deceleration and the like, processed in an anti-skid control unit (9), and a second braking system, controlled by a single valve (V.sub.2), is provided connected to the second braking cylinders in both wheels. The control signals for the second valve (V.sub.2) are generated as a function of the signals arising in the first system (I) by a logic circuit (15-25) including timing elements (15, 16, 19, 21) responsive to leading and trailing flanks, respectively, of opening and closing signals arising in the first braking system (I) under command of the wheel anti-lock or anti-skid control unit (9), to drop braking pressure in the second system (II) if unstable operation of the wheels, based on braking in the first system (I) occurs, and raising braking pressure only after a time delay (19; T.sub.2) if an increase in braking pressure in the first system occurred. As an override safety, response of the braking control unit (9) is indicated by a separate override signal, absence of which leaves the second braking system (II) unaffected, but presence thereof prevents raising of braking pressure in the second system during response of the anti-skid unit and controlling the first system.

摘要： The invention relates to an anti-locking wheel control system in which control signals for the variation of the brake pressure are derived from the rotary motion behavior of the vehicle wheels and in which a test circuit is provided, which initiates a test for at least one wheel brake when a signal appears which indicates a tendency toward locking, in which test the over-braked vehicle wheel enters a state of high slippage, whereby the test circuit determines how the wheel behaves at the given coefficient of friction between the road surfaces and the tire, and whereby on the basis of this determination, the test circuit either provides a state in which the brake pressure is regulated or else switches to a state in which the control is made ineffective for at least some of the wheel brakes.
