The invention relates to a method and an apparatus for regulating brake pressure based on the inlet pressure set by the driver.
A method and an apparatus for controlling the brake system of a vehicle is disclosed in the unpublished German Patent Application 1 95 01 760.1 of Jan. 21, 1995. In it the braking force at the wheel brakes is controlled, at least in certain operating conditions, by an active braking force increase or decrease according to the driver's wish. The derivation of the driver's wish from the force applied at the brake pedal would be desirable. In the prior-art system the force applied is determined by measuring the inlet pressure (pressure in the main brake cylinder). This does not coincide in every operating situation with the force actually applied by the foot.
It is the object of the invention to improve the detection of the driver's brake demand by measuring the inlet pressure.
