Abstract: The circuit configuration for a brake system having an anti-locking control generates pulse-type brake pressure control signals. For pressure rebuild-up after a pressure decrease, brake pressure is applied first at a steep and subsequently at a flatter gradient, this being achieved by a variable pulse (P1) and by short fixed pulses (P2) succeeding one another at a large interval. Circuits are provided rendering dependent the pulse and pulse break times (T.sub.1, T.sub.2, T.sub.k) determining the pressure build-upon the duration of the pressure build-up (T.sub.1) during the steep-rise build-up in the preceding cycle,on the duration (T.sub.1 +nT.sub.2) of the entire pressure build-up in the preceding cycle, andon the duration (T.sub.o) of the preceding pressure decrease, with the pulse times being so dimensionedthat, at a constant coefficient of friction and at a constant static pressure, the locking limit of the wheel is rereached after a predetermined period of time or after a predetermined pulse number. The duration of the variable and of the fixed pressure build-up pulses is computed from the pressure build-up of the preceding pressure or determined from a stored Table.

Abstract: A brake system with anti-lock and/or traction slip control, wherein quantities (.DELTA.t.sub.EV, .DELTA.t.sub.AV) determining the pressure in the wheel brakes (10, 11) are measured and assessed. A wheel pressure pattern (p(t)) is formed from these quantities by integration which, by approximation, represents the pressure variation in the wheel brakes (10, 11). The output signal of the integrator (20) is fed back to the control logic (16) and assessed for slip control and/or braking pressure control. For the integration, taken into account are the braking-pressure-increase and braking-pressure-decrease characteristic curves (P.sub.A, P.sub.E) and the initial conditions (21) which represent the initial pressure upon commencement of the control.

Abstract: A braking pressure regulating device, in particular an anti-lock control device for hydraulic brake systems of automotive vehicles, comprising a master cylinder and a pressure modulator for the variation of the hydraulic pressure in the wheel cylinders during the braking pressure control mode. The device is equipped with a motor-driven pump (8) for generating a hydraulic pressure and with an electronic control unit (5) for controlling the valves of the pressure modulator (2). During the braking pressure control mode, the working chambers (10, 15) of the master cylinder (16) are exposed to pump pressure. Caused by the pump pressure in the working chamber (10), the push rod piston (11) and thus the brake pedal (1) disadvantageously are returned into their basic position in prior-art devices. The present arrangement provides that the switching positions of the regulating valve incorporated in the push rod piston are shifted into the cylinder during the braking pressure control mode. Therefore the brake pedal is not fully reset during the control mode. The operating comfort of the brake pedal is thereby augmented.

Abstract: A hydraulic servo brake system with slip control. Brake circuits (18, 22, 25) with supply valves (28, 32, 35) and discharge valves (29, 33, 36) for the control of the wheel cylinder pressures during slip control are provided. Throttle points (38) are arranged within the supply valves. Each supply valve is bridged by an auxiliary valve (31, 34, 37) which is switchable into the closed position when the slip control action sets in. In this manner, the pressure gradient for the brake pressure build-up in the wheel cylinders is high before the slip control and low during the slip control.

Abstract: A slip-controlled brake system for automotive vehicles contains a braking pressure modulator (5) operated as a function of the deceleration and having an inert mass (10) which rotates with the vehicle wheel and which, upon a deceleration of the wheel, against resetting forces, is axially displaceable on a shaft (9) rotating with the wheel velocity. A wheel deceleration threshold value being exceeded, a valve member (21) will be actuated and thus the braking pressure will be prevented from increasing further or there even will be a reduction of the braking pressure. The deceleration threshold value is not constant but variable dependence on the braking pressure in the wheel brake (4) of the controlled vehicle wheel. Thereby an adaption of control to the road conditions or rather to the momentary friction coefficient is achieved.

Abstract: A control circuit for adapting slip control of an anti-skid brake system of an automotive vehicle comprising a friction coefficient identification circuit (31, 31'). Upon the instabilization of a wheel the braking pressure control signals controlling the slip by actuating solenoid valves (36-41) are varied by the output signal of the circuit (31, 31') as a function of the momentary deceleration (v.sub.R) of the fastest wheel and/or on the momentary pressure in the hydraulic brake circuits (52, 53, 54) and thus are adapted to the momentary friction coefficient, which in particular depends on the road condition. In one instance, the gradient of the vehicular reference velocity is varied in dependence on the friction coefficient.

Abstract: A circuit configuration for a slip-controlled vehicle brake system is equipped with sensors (10-13) for the determination of the rotational behavior of the front and the rear wheels and with electronic circuits (18, 30) for the processing, logic combining and monitoring of the sensor signals and for the generation of control signals. The control signals allow control of the braking pressure variation at the wheels. Upon failure or malfunction of a sensor (10-13) or in the event of an interference in the signal path, the brake slip control is switched over to being responsive to the rotational behavior of another wheel according to a predetermined selection criterion.
