    • 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.

    • 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.
    • 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。

    • A circuit arrangement for a drive slip control system assesses the speed (vER) measured at a driven spare wheel with a correction factor K(t) in order to maintain or improve the control function even when a smaller spare wheel is fitted. This correction factor (K(t)) is found with the drive slip control inoperative by the comparison between axles of the rotation speeds (vna1, vna2, va, vER) of the wheels on one axle and the comparison of the rotation speed differences measured on the driven and undriven axles. On the transition from very slippery road surfaces (νlowuniform) to dry ones (νhighuniform) without the prior calculation of the correction factor, the slip threshold (S) is temporarily raised. When running on different friction factors on the right and left (ν-split), a raised slip threshold (SER) becomes effective on the spare wheel if it is fitted on the high-friction factor side.
