    • In a method for the adaptive control of the hydraulic pump of a brake system containing low pressure accumulator (NDS1,2) which take up the pressure fluid discharged in the case of control from the wheel brakes and which are evacuated by the hydraulic pump (HP), first the brake pressure pattern (pR) is determined for each individual wheel with the aid of a wheel pressure model. Then a volume model (VM1,2) is formed on the basis of the wheel pressure model for each individual brake circuit, which volume model indicates, by way of approximation, the filling level of the low pressure accumulators (NDS1,2). The maximum filling level (MaxV) and the control frequency or the time interval (T) between two successive brake pressure decreasing phases (Ph2) are determined. The delivery capacity of the hydraulic pump (HP) is so dimensioned that the time interval (T) between two successive brake pressure decreasing phases (Ph2) is just adequate for completely evacuating the low pressure accumulators (NDS1,2).
    • 在用于对包含低压蓄能器(NDS1,2)的制动系统的液压泵的自适应控制的方法中,该低压蓄能器(NDS1,2)在从车轮制动器控制的情况下吸收压力流体并且由液压泵(HP ),首先借助于车轮压力模型为每个单独的车轮确定制动压力模式(pR)。 然后,基于每个单独制动电路的车轮压力模型形成体积模型(VM1,2),该体积模型通过近似表示低压蓄能器(NDS1,2)的填充水平。 确定两个连续的制动压力降低阶段(Ph2)之间的最大填充水平(MaxV)和控制频率或时间间隔(T)。 液压泵(HP)的输送能力的尺寸使得两个连续的制动压力降低阶段(Ph2)之间的时间间隔(T)仅仅足以完全排空低压蓄能器(NDS1,2)。

    • Disclosed is a method for identifying a critical braking operation of a two-track vehicle during cornering, which features the steps of detecting the running behaviour of a left-hand side wheel and of a right-hand side wheel, of comparing the running behaviour and/or of evaluating the time variation of at least one left-hand side wheel or right-hand side wheel, and of identifying a critical braking operation on the basis of the result of the comparison and/or of the result of the evaluation. As a reaction, there may ensue the reduction of the braking pressure of a wheel on the inside of the corner in response to identification. A device for identifying a critical braking operation of a two-track vehicle during cornering includes a detecting device (403a, b, 408a, b) for detecting the running behaviour of a left-hand side wheel and of a right-hand side wheel (301a-d), a first comparing device (409-412) for comparing the running behaviour and/or an evaluating device (404-407) for evaluating the time variation of at least one left-hand side wheel or one right-hand side wheel, and an identifying device (413) for identifying a critical braking operation on the basis of the output of the comparing device and/or of the output of the evaluating device. Moreover, a modifying device (315) can be provided for reducing the braking pressure of a wheel on the inside of the corner in response to identification.
