摘要： A brake pressure regulating device, in particular an autoblocking device for hydraulic brake systems for motor vehicles, comprises a master cylinder and a pressure modulator for changing the hydraulic pressure in the wheel brake cylinders during the brake pressure regulating mode. The device is fitted with a motor-driven pump (8) for producing a hydraulic pressure and with an electronic regulator (5) for controlling the valves of the pressure modulator (2). During the regulating mode, the working chambers (10, 15) of the master cylinder (16) are under pump pressure. In prior art devices, the pump pressure in the working chamber (10) forces the push-rod pistons (11) and hence the brake pedal (1) back into their normal position. This is regarded as disadvantageous. According to the invention, the switching positions of the regulating valve lodged in the pressure rod piston are displaced into the cylinder during the brake pressure regulating mode. In this way, the brake pedal is not fully restored to its normal position during the regulating mode. Brake pedal operator comfort is thereby enhanced.

摘要： In an antilock hydraulic braking system, a throttle is inserted in the throttle valve (8) in the brake line during brake slip control. The pumps (12, 13) pump the hydraulic fluid through the throttle to the wheel brake. The pressure in the wheel brake is controlled only by an outlet valve (11) the open cross-section of which is chosen so that the quantity of hydraulic fluid discharged through the outlet valve (11) is greater than the quantity of hydraulic fluid delivered by the pumps (12, 13) to the wheel brake via the throttle. Hence, when the outlet valve is open, the pressure in the brake decreases, whereas when the valve (11) is closed, the pressure in the brake increases. The invention relates to different ways of controlling the throttle valve (8).

摘要： The invention concerns a slip-controlled brake system with a particularly reliable switching concept designed to prevent complete failure or overbraking of the rear brakes in the event of an electrical or electronic fault occurring. To this end, a control valve (3) (functional block F), which in its normal position is closed with no electromagnetic current, is connected into the main pressure line (2) in series with the rear-brake inlet valve (1) which in its normal position is open with no electromagnetic current, the control valve (3) having a bypass line (4) which is controlled in dependence on the brake pressure.

摘要： Described is a device designed to hold a vehicle fitted with an electronic anti-blocking system on a slope. The device has electrically operated multi-way valves (6, 7, 22, 23, 28, 29) fitted in at least one hydraulic-fluid line leading from a brake-pressure source (1) to the inlet valves (12, 13, 14, 15). The multi-way valves are open in the normal position and can be switched over to a closed position. Fitted parallel to the multi-way valves are pressure-relief valves (20, 21, 24, 25, 20, 31). The multi-way valves act as vehicle-holding valves. When the brake-pressure source (1) is in the released position, electronic circuits (not shown) control the vehicle-holding valves (6, 7, 22, 23, 28, 29) in response to hold commands or hold signals and/or start up the hydraulic pump (8, 27) of an auxiliary pressure source (5, 26)

摘要： A hydraulic, antilock braking system has a pump (8) and a master cylinder (1). The valve for regulating the pump pressure is integrated in the master cylinder (1) and is composed of a combined seal (30, 34) that cooperates with a compensating bore (36). The seal (30, 34) is composed of an inner elastic ring (37) and an outer sliding ring (38). The communication required between the reservoir (7) and the brake circuits in order to fill up the brake circuits through a nonreturn valve is established through the nonreturn valves (10, 11) of the pump (9). A packing (41) may be added to the double seal (30, 34) in order to reliably seal the working chamber (39, 40) even when small leakage currents occur through the double seal (30, 34).

摘要： In a circuit arrangement for a brake system with antilock or anti drive slip system and with switching circuits for detecting bends, side reference speeds (13, 14) are derived by means of selection circuits (8, 9) each of which selects a controlling wheel speed in accordance with given criteria and by means of filter stages (10, 11) with variable time constants (12). A difference signal (DVS) (15) whose amplitude can be varied by counter coupling is derived from the side reference speeds (SRGL, SRGR). An adaptation circuit (18) triggered by this difference signal (DVS) in function of the vehicle reference speed (VREF) influences the control thresholds of the antilock and anti drive slip system (7) in order to adapt the control to the specific characteristics of a bend being negotiated.

摘要： Proposed is equipment for vehicles fitted with anti-slip control by braking action, the equipment including a hydraulic pump (21, 22) but no hydraulic accumulator. The equipment comprises a sensor (SD) and/or a circuit for the determination of driving situations in which there is a tendency for the drive wheels to spin. For instance, the angular speed of the engine throttle-valve flap (28) is measured and analysed. Auxiliary-pressure generation is started up as soon as the signal representing the spin tendency exceeds a certain limit.

摘要： A circuit arrangement for a brake system with anti-lock control generates pulse-shaped brake pressure control signals. In order to increase the pressure again after a pressure drop, the brake pressure is first controlled with a steep gradient and then with a flatter gradient. This is achieved by means of a variable pulse (P1) and by means of short constant pulses (P2) in rapid succession. Switch circuits determine the pulse and pulse pause times (T1, T2, Tk) which determine the pressure increase - from the duration of the presure build-up (T1) during the build-up with steep increase in the preceding cycle - from the duration (T1 + nT2) of the total pressure build-up in the preceding cycle - from the duration (T0) of the preceding pressure build-up. The pulse times are chosen so that at constant coefficient of friction and uniform preliminary pressure the locking limit of the wheel is attained again after a predetermined time interval or after a predetermined number of pulses. The duration of the variable and constant pressure build-up pulses is computed from the pressure build-up of the preceding pressure or read from a stored table.
摘要翻译：具有防抱死控制的制动系统的电路装置产生脉冲形制动压力控制信号。为了在压降之后再次增加压力，制动压力首先用陡峭的梯度控制，然后用较平坦的梯度来控制。这通过可变脉冲（P1）和快速连续的短暂恒定脉冲（P2）来实现。开关电路确定脉冲和脉冲暂停时间（T1，T2，Tk），其决定压力增加 - 从累积期间的累积持续时间（T1）到前一周期的急剧增长 - 从持续时间（T1 + nT2），从前一个压力累积的持续时间（T0）开始。选择脉冲时间使得在恒定的摩擦系数和均匀的预备压力下，在预定时间间隔之后或在预定数量的脉冲之后再次获得车轮的锁定极限。可变和恒定压力累积脉冲的持续时间是从先前压力的压力建立或从存储的表中读取来计算的。

摘要： To control a brake system with anti-blocking and/or anti-skid device, the quantities ( DELTA tEV, DELTA tAV) which determine the pressure in the wheel brakes (10, 11) are measured and evaluated. These measured values are integrated in order to build a wheel pressure model (p(t)) which reproduces approximately the variation of pressure in the wheel brakes (10, 11). The output signal from the integrator (20) is returned to the logical control circuit (16) and evaluated for the purposes of skid control or brake pressure control. Allowance is made during integration for the brake pressure build-up and reduction characteristic curves (pA, pE) and the initial conditions (21), which reproduce the initial pressure at the onset of control.
