    摘要: 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).

    摘要: The present invention relates to a method of detecting the roll angle of a cornering vehicle which comprises at least one axle and at least two wheels, the vehicle being equipped with a transverse acceleration sensor means which senses the transverse acceleration that acts on the center of gravity of the automotive vehicle generally in the horizontal plane of the vehicle. To provide a method which does not require an additional sensor means and is virtually independent of given vehicle characteristics or dimensions, the component of the transverse acceleration which essentially acts in the horizontal plane of the vehicle is detected by the transverse acceleration sensor means during cornering. In addition, a condition variable which is correlated to the centrifugal acceleration acting on the center of gravity is detected, and the roll angle of the vehicle is calculated from the difference between the detected component of the transverse acceleration and the determined centrifugal acceleration, the said difference being weighted with a factor.

    摘要: 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.
