Abstract:
A system and method for controlling brake pressure is described wherein desired brake pressures are determined. From these pressures, valve activation control times are calculated and thus the pressure is directed into the wheel brake cylinders. The wheel brake cylinder pressures are determined from the activation times of the valves and the brake circuit pressure. They are also used for determining the desired pressure. In addition a pump is provided which makes it possible to generate higher pressures in the wheel brake cylinders than those actuated by the driver. The brake circuit pressures required for the above-described determination of the desired pressure are determined by calculating a model and using the measured inlet pressure.
