    摘要: A circuit configuration for a brake system with anti-lock control and/or traction slip control composed of circuits for conditioning wheel sensor signals, controller circuits for analyzing and processing the conditioned sensor signals and for generating braking pressure control signals, monitoring circuits which process the sensor signals irrespective of the controller circuits, and circuits for exchanging and comparing signals of the controller circuits with corresponding signals of the monitoring circuits. The monitoring circuits have a simpler structure than the controller circuits. The control philosophy is reproduced in the monitoring circuits. In particular, the control phases are determined by the reproduction on the basis of the same control criteria and control parameters which the controller circuits use. The signals of the reproduction circuits are united with the valve-excitation signals in correlation circuits for the detection of errors.

    摘要: To control a brake slip control apparatus, the rotational behavior of the wheels or of the axles is sensed with the aid of sensors, and the sensor signals for the generation of valve control signals, by which the braking pressure at the wheels is controlled dependent upon the wheel rotational behavior, will be processed electronically. On the basis of these sensor signals, valve control signals will be produced in at least two independently acting, synchronously driven logical circuit units, which may be integrated circuit configurations or complete "microcontrollers" or single-chip-microcomputers, and the signals' waveforms of each of the two circuit units can be compared and checked for agreement externally and internally at corresponding locations within the two circuit units. Upon the occurrence of variations in the external and/or the internal signals or in the signals' waveform, there will be caused, initiated or prepared a complete or partial disconnection of the brake slip control. A circuit configuration for implementing this method comprises a synchronizable astable multivibrator to process the sensor signals, a valve driver circuit including a level adjusting circuit as well as monitoring circuits for disconnecting the current supply for the regulator and for blocking the valve drivers in the event of interferences or variations in the signals' waveform occurring within the two circuit units. The monitoring circuits, one for each of the two circuit units, act on at least one transistor connected in series in the exciter circuit of a relay, by which the current supply is established or interrupted.

    摘要: Method and circuit configuration for controlling the flow rate of an electromotively driven hydraulic pump which is activated by a variable pulse/pulse-break train for controlling the auxiliary pressure supply of a brake system including anti-lock control (ABS) and traction slip control by brake management (BASR). The generator voltage produced by the pump motor during times of pulse break is evaluated as a standard of the rotational speed of the pump. The nominal value of the pump speed is compared with the actual value of the pump speed in a control circuit, and the new correcting variable for the pump activation is derived from the difference.

    摘要: For the generation of a vehicle reference speed to serve as the reference value for the control of brake slip and/or traction slip in automotive vehicles, the rotational behavior of the controlled wheels is measured. The vehicle reference speed is defined by virtue of the rotational behavior of the individual wheels by way of logic combining, selection according to predetermined criteria and/or comparison with predetermined limit values. The wheel rotational behavior of each wheel is evaluated in comparison to the wheel-related vehicle reference speed (V.sub.Ref) according to several predefined criteria is then classified into reference-defining periods. As a function of ascertained reference-defining period, a vehicle reference value (b.sub.fzg) related to the individual wheel is determined which, together with the wheel-related vehicle reference values of the other wheels, determines the vehicle reference speed.

    摘要: A slip-controlled brake system for road vehicles in which one front wheel (VR, VL) and one rear wheel (HR, HL) at a time are connected to a common braking pressure control channel wherein the braking pressure variation in the two braking pressure control channels is influenced in dependence on predetermined selection criteria such as "select-low" and "select-high" criteria. A cornering identification circuit (20') is provided which adds up the slip values (S.sub.VL, S.sub.HL, S.sub.VR, S.sub.HR) of the two wheels of one side of the vehicle and compares them with the slip value sum (S.sub.L, S.sub.R) of the wheels of the other side of the vehicle. When the difference of the slip value sums of the two sides of the vehicle exceeds a limit value, the selection criteria and, hence, the braking pressure variations are temporarily changed. Because of the cornering identification circuit, it is possible to generate information about the driving direction, i.e. about straight-onward driving or cornering, and to logically process it within the scope of brake slip control or traction slip control and irrespective of the number of existing braking pressure control channels.

    摘要: A slip-controlled brake system for automotive vehicles with a driven axle and a non-driven one has a braking pressure generator (10) connected to an auxiliary pressure source (9), to the braking pressure generator (10) the wheel brakes of a front wheel (VR, VL) and of a rear wheel (HR, HL) are connected by way of two separate pressure medium circuits. The braking pressure in the two circuits (I, II) at first is jointly controlled by means of an inlet valve and an outlet valve each (5, 13 and 7, 14 respectively). However, a far-reaching decoupling of the pressure variation in the two wheel brakes connected to one circuit (I or II, respectively) is achieved by means of additional 2/2-way valves (6, 15) in the pressure medium line towards the wheel brakes of the non-driven wheels (HR, HL).
