Abstract
In a method for the adaptive control of the hydraulic pump of a brake system containing low pressure accumulator (NDS ) 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 (p ) 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 (NDS ). 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 (NDS ).
