A process and an apparatus for pressure control, in particular, to adjust braking pressures in a utility vehicle, are proposed. Two individual controllers (10, 11) are assigned respectively to an inlet valve (2) and to a discharge valve (3). A pilot control value consisting of a fixed value yv and of a memorized value DELTA yv is additively input to the output values of these controllers. The memorized components DELTA yv are the integration result of the I (integration) components of the individual controllers (10, 11) for the duration of a pressure increase (inlet valve) or pressure decrease (discharge valve). The memorizing process is ended after approximately five to ten brake applications and the value of DELTA yv which is then reached is used as an individual pilot control value.
