The invention relates to a method for improving the control behavior of
motor vehicle control systems such as ABS, ESP, etc. comprising
electrically driven hydraulic pumps, inlet and outlet valves and
low-pressure accumulators, wherein the low-pressure accumulators
accommodate, at least in part, pressure fluid that is discharged from
wheel brakes in a control operation, wherein the hydraulic pumps are used
to return the pressure fluid into a master cylinder, in particular tandem
master cylinder, wherein the delivery behavior of the hydraulic pumps is
controlled in dependence on pressure values, and wherein the actuation of
the hydraulic pumps takes place in conformity with demand, i.e. by
evaluating slip variation, wherein in a pressure increase phase, the
pressure fluid is intermediately stored in the low-pressure accumulators
and there is no return delivery of the pressure fluid into the master
cylinder until either a pressure increase phase or pressure buildup
commences, or a critical filling level of the low-pressure accumulator
necessitates actuation of the hydraulic pumps for safety reasons, with
the result of balancing the volume flow demand and the delivery volume
flow and thus achieving a reduction of vibrations of the brake pedal.
Further, the invention relates to a computer program product defining an
algorithm that comprises a method for improving the control behavior of
motor vehicle control systems.
